NEW QUESTION # 35
When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power.
What does -20 dBm correspond to?

• A. .01 mw
• B. .-1 mW
• C. 1mW
• D. 10 mW

Answer: A

Explanation:
Explanation
dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) =
1mW * 10^(-20/10) = 0.01 mW References:https://www.rapidtables.com/convert/power/dBm_to_mW.html

NEW QUESTION # 37
Match each AAA service with its correct definition (Matches may be used more than once or not at all)

Answer:

Explanation:

Explanation
AAA Authentication, Authorization, and Accounting (AAA) Authentication, Authorization, and Accounting (AAA) is a framework that provides security services for network access control . AAA consists of three components:
Authentication: The process of verifying the identity of a user or device that wants to access the network based on credentials such as username and password , certificates , tokens , etc . Authentication can use different protocols such as PAP , CHAP , EAP , RADIUS , TACACS+ , etc .
Authorization: The process of granting or denying access to network resources based on the identity and privileges of a user or device . Authorization can use different methods such as ACLs , RBAC , MAC , DAC , etc .
Accounting: The process of recording and reporting the activities and usage of network resources by users or devices . Accounting can use different formats such as syslog , SNMP , NetFlow , etc .
service. Here is my answer:
The correct match for each AAA service with its definition is:
Accounting: C. Tracking user activity on the network
Authentication: D. Who can access the network based on credentials/certificates Authorization: B. Control users access on the network The other options are not correct matches because:
A list of rules that specifies which entities are permitted or denied access: This option is a definition of an access control list (ACL) Access Control List (ACL) Access Control List (ACL) is a list of rules that specifies which entities are permitted or denied access to a network resource such as a router , switch , firewall , server , etc . ACLs can be based on different criteria such as source and destination IP addresses , port numbers , protocol types , time of day , etc . ACLs can be applied to different interfaces or directions such as inbound or outbound . ACLs can be verified by using commands such as show access-lists , show ip access-lists , debug ip packet , etc . , not an AAA service.
Who can access the network based on credentials/certificates: This option is a definition of authentication, not authorization. Authorization is the process of granting or denying access to network resources based on the identity and privileges of a user or device, not based on credentials/certificates.

NEW QUESTION # 38
Which statement is correct when comparing 5 GHz and 6 GHz channels with identical channel widths?

• A. 5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels
• B. 5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels
• C. 5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels
• D. 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels

Answer: D

Explanation:
Explanation
The correct statement when comparing 5 GHz and 6 GHz channels with identical channel widths is that 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels.
This statement reflects the fact that higher frequency signals tend to have higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Higher attenuation means that higher frequency signals have shorter range and lower throughput than lower frequency signals. Some facts about this statement are:
5 GHz channels have lower frequency than 6 GHz channels, which means they have lower attenuation than 6 GHz channels.
Lower attenuation means that 5 GHz channels can travel longer distances and provide higher throughputs to clients than 6 GHz channels with identical channel widths.
However, the difference in distance and throughput between 5 GHz and 6 GHz channels may not be significant in indoor environments where there are many obstacles and reflections that affect signal propagation.
The advantage of using 6 GHz channels over 5 GHz channels is that they offer more spectrum availability, less interference, and more non-overlapping channels than 5 GHz channels.
The other options are not correct because:
5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances or provide the same throughputs as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not provide the same throughputs as
6 GHz channels due to higher attenuation of higher frequency signals.

Technology
Use case
1) 802.1Q
802.1Q is a standard that defines how to create and manage virtual LANs (VLANs) on a network. VLANs allow network administrators to logically segment a network into different broadcast domains, improving security, performance, and manageability. 802.1Q tags Ethernet frames with an additional VLAN header that contains a VLAN identifier (VID), which indicates which VLAN the frame belongs to1.
2) 802.1X
802.1X is a standard that defines how to provide port-based network access control (PNAC) on a network.
PNAC allows network administrators to authenticate and authorize devices before granting them access to network resources. 802.1X uses the Extensible Authentication Protocol (EAP) to exchange authentication messages between a supplicant (a device that wants to access the network), an authenticator (a device that controls access to the network, such as a switch), and an authentication server (a device that verifies the credentials of the supplicant, such as a RADIUS server)
3) LACP
LACP stands for Link Aggregation Control Protocol, which is part of the IEEE 802.3ad standard that defines how to bundle multiple physical links into a single logical link, also known as a link aggregation group (LAG) or an EtherChannel. LAGs provide increased bandwidth, load balancing, and redundancy for network connections. LACP controls the dynamic addition and removal of ports to groups, ensuring that only ports with compatible configurations can form a LAG3.
4) LLDP
LLDP stands for Link Layer Discovery Protocol, which is part of the IEEE 802.1AB standard that defines how to discover and advertise information about neighboring devices on a network. LLDP operates at Layer 2 of the OSI model and uses TLVs (type-length-value) to exchange information such as device name, port number, VLAN ID, capabilities, and power requirements. LLDP can be used to identify a voice VLAN to an IP phone by sending a TLV that contains the voice VLAN ID and priority.

NEW QUESTION # 41
You are configuring a network with a stacked pair of 6300M switches used for distribution and layer 3 services. You create a new VLAN for users that will be used on multiple access stacks of CX6200 switches connected downstream of the distribution stack You will be creating multiple VLANs/subnets similar to this will be utilized in multiple access stacks What is the correct way to configure the routable interface for the subnet to be associated with this VLAN?

• A. Create a physically routed interface in the subnet on the 6300M stack for each downstream switch.
• B. Create an SVl in the subnet on the 6300M stack.
• C. Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet
• D. Create an SVl in the subnet on each downstream switch

Answer: B

Explanation:
Explanation
The correct way to configure the routable interface for the subnet to be associated with this VLAN is to create an SVI Switched Virtual Interface (SVI) Switched Virtual Interface (SVI) is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN . SVIs are used to enable inter-VLAN routing , provide gateway addresses for hosts in VLANs , apply ACLs or QoS policies to VLANs
, etc . SVIs have some advantages over physical routed interfaces such as saving interface ports , reducing cable costs , simplifying network design , etc . SVIs are usually numbered according to their VLAN IDs (e.g., vlan 10) and assigned IP addresses within the subnet of their VLANs . SVIs can be created and configured by using commands such as interface vlan , ip address , no shutdown , etc . SVIs can be verified by using commands such as show ip interface brief , show vlan , show ip route , etc . in the subnet on the 6300M stack.
An SVI is a virtual interface on a switch that represents a VLAN and provides Layer 3 routing functions for that VLAN. Creating an SVI in the subnet on the 6300M stack allows the switch to act as a gateway for the users in that VLAN and enable inter-VLAN routing between different subnets. Creating an SVI in the subnet on the 6300M stack also simplifies network design and management by reducing the number of physical interfaces and cables required for routing.
The other options are not correct ways to configure the routable interface for the subnet to be associated with this VLAN because:
Create a physically routed interface in the subnet on the 6300M stack for each downstream switch: This option is incorrect because creating a physically routedinterface in the subnet on the 6300M stack for each downstream switch would require using one physical port and cable per downstream switch, which would consume interface resources and increase cable costs. Creating a physically routed interface in the subnet on the 6300M stack for each downstream switch would also complicate network design and management by requiring separate routing configurations and policies for each interface.
Create an SVl in the subnet on each downstream switch: This option is incorrect because creating an SVI in the subnet on each downstream switch would not enable inter-VLAN routing between different subnets, as each downstream switch would act as a gateway for its own VLAN only. Creating an SVI in the subnet on each downstream switch would also create duplicate IP addresses in the same subnet, which would cause IP conflicts and routing errors.
Create an SVl in the subnet on the 6300M stack, and assign the management address of each downstream switch stack to a different IP address in the same subnet: This option is incorrect because creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would not enable inter-VLAN routing between different subnets, as each downstream switch would still act as a gateway for its own VLAN only. Creating an SVI in the subnet on the 6300M stack, and assigning the management address of each downstream switch stack to a different IP address in the same subnet would also create unnecessary IP addresses in the same subnet, which would waste IP space and complicate network management.

NEW QUESTION # 43
You need to drop excessive broadcast traffic on ingress to an ArubaOS-CX switch What is the best technology to use for this task?

• A. DWRR queuing
• B. Strict queuing
• C. QoS shaping
• D. Rate limiting

Answer: D

Explanation:
Explanation
The best technology to use for dropping excessive broadcast traffic on ingress to an ArubaOS-CX switch is rate limiting. Rate limiting is a feature that allows network administrators to control the amount of traffic that enters or leaves a port or a VLAN on a switch by setting bandwidth thresholds or limits. Rate limiting can be used to prevent network congestion, improve network performance, enforce service level agreements(SLAs), or mitigate denial-of-service (DoS) attacks. Rate limiting can be applied to broadcast traffic on ingress to an ArubaOS-CX switch by using the storm-control command in interface configuration mode. This command allows network administrators to specify the percentage of bandwidth or packets per second that can be used by broadcast traffic on an ingress port. If the broadcast traffic exceeds the specified threshold, the switch will drop the excess packets.
The other options are not technologies for dropping excessive broadcast traffic on ingress because:
DWRR queuing: DWRR stands for Deficit Weighted Round Robin, which is a queuing algorithm that assigns different weights or priorities to different traffic classes or queues on an egress port. DWRR ensures that each queue gets its fair share of bandwidth based on its weight while avoiding starvation of lower priority queues. DWRR does not drop excessive broadcast traffic on ingress, but rather schedules outgoing traffic on egress.
QoS shaping: QoS stands for Quality of Service, which is a set of techniques that manage network resources and provide different levels of service to different types of traffic based on their requirements.
QoS shaping is a technique that delays or buffers outgoing traffic on an egress port to match the available bandwidth or rate limit. QoS shaping does not drop excessive broadcast traffic on ingress, but rather smooths outgoing traffic on egress.
Strict queuing: Strict queuing is another queuing algorithm that assigns different priorities to different traffic classes or queues on an egress port. Strict queuing ensures that higher priority queues are always served before lower priority queues regardless of their bandwidth requirements or weights. Strict queuing does not drop excessive broadcast traffic on ingress, but rather schedules outgoing traffic on egress.

NEW QUESTION # 44
What happens when the signal from an AP weakens by being absorbed as it moves through an object?

• A. Aruba Central dynamically moves clients to neighboring APs
• B. Signal to Noise Ratio (SNR) decreases
• C. Signal to Noise Ratio (SNR) increases
• D. APs will use bonded channels to decrease latency to clients

Answer: B

Explanation:
Explanation
Signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover1. When the signal from an AP Access Point. AP is a device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. weakens by being absorbed as it moves through an object, such as a wall or a furniture, the signal power decreases. This reduces the SNR and affects the quality of the wireless connection. The noise power may also increase due to interference from other sources, such as other APs or devices operating in the same frequency band2. Therefore, the correct answer is that SNR decreases when the signal from an AP weakens by being absorbed as it moves through an object. References: 1

NEW QUESTION # 45
You need to troubleshoot an Aruba CX 6200 4-node VSF stack switch that fails to boot correctly Select the option that allows you to access the switch and see the boot options available for OS images and ServiceOS.

• A. Conductor USB-C console port
• B. Conductor mgmt port using SSH
• C. Member 2 switch mgmt port
• D. Member 2 RJ-45 console port

Answer: A

Explanation:
Explanation
The option that allows you to access the switch and see the boot options available for OS images and ServiceOS is Conductor USB-C console port. This option provides direct access to ServiceOS, which is an operating system that runs on Aruba CX switches independently of AOS-CX Aruba Operating System CX (AOS-CX) is an operating system that runs on Aruba CX switches . ServiceOS provides low-level functions such as booting, firmware upgrades, password recovery, hardware diagnostics, switch stacking, and system recovery. ServiceOS can be accessed through one of two methods:
Conductor USB-C console port: This method allows you to connect your PC or laptop to the USB-C console port on any member switch in a VSF stack using a USB-C cable. This method provides direct access to ServiceOS without requiring any configuration or authentication on AOS-CX.
AOS-CX CLI: This method allows you to access ServiceOS through AOS-CX CLI using SSH or Telnet protocols. This method requires you to configure an IP address on AOS-CX and authenticate with your username and password.
To see the boot options available for OS images and ServiceOS, you need to access ServiceOS through Conductor USB-C console port and enter boot menu command at ServiceOS prompt.
The other options do not allow you to access the switch and see the boot options available for OS images and ServiceOS because:
Member 2 RJ-45 console port: This option allows you to connect your PC or laptop to the RJ-45 console port on any member switch in a VSF stack using an RJ-45 cable. This option provides direct access to AOS-CX CLI, not ServiceOS.
Member 2 switch mgmt port: This option allows you to connect your PC or laptop to the switch mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH or Telnet protocols, not ServiceOS.
Conductor mgmt port using SSH: This option allows you to connect your PC or laptop to the mgmt port on any member switch in a VSF stack using an Ethernet cable. This option provides indirect access to AOS-CX CLI through SSH protocol, not ServiceOS.

NEW QUESTION # 47
A network technician has successfully connected to the employee SSID via 802 1X Which RADIUS message should you look for to ensure a successful connection?

• A. Access-Accept
• B. Success
• C. Authenticated
• D. Authorized

Answer: A

Explanation:
Explanation
The RADIUS message that you should look for to ensure a successful connection via 802.1X is Access-Accept. This message indicates that the RADIUS server has authenticated and authorized the supplicant (the device that wants to access thenetwork) and has granted it access to the network resources. The Access-Accept message may also contain additional attributes such as VLAN ID, session timeout, or filter ID that specify how the authenticator (the device that controls access to the network, such as a switch) should treat the supplicant's traffic.
The other options are not RADIUS messages because:
Authorized: This is not a RADIUS message, but a state that indicates that a port on an authenticator is allowed to pass traffic from a supplicant after successful authentication and authorization.
Success: This is not a RADIUS message, but a status that indicates that an EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). exchange has completed successfully between a supplicant and an authentication server.
Authenticated: This is not a RADIUS message, but a state that indicates that a port on an authenticator has received an EAP-Success message from an authentication server after successful authentication of a supplicant.

NEW QUESTION # 48
Review the configuration below.

Why would you configure OSPF to use the IP address 10.1.200.1 as the router ID?

• A. The loopback interface state is dependent on the management interface state and reduces routing updates.
• B. The IP address associated with the loopback interface is routable and prevents loops
• C. The loopback interface state Is independent of any physical interface and reduces routing updates.
• D. The IP address associated with the loopback interface is non-routable and prevents loops

Answer: C

Explanation:
Explanation
The reason why you would configure OSPF Open Shortest Path First (OSPF) is a link-state routing protocol that dynamically calculates the best routes for data transmission within an IP network. OSPF uses a hierarchical structure that divides a network into areas and assigns each router an identifier called router ID (RID). OSPF uses hello packets to discover neighbors and exchange routing information. OSPF uses Dijkstra's algorithm to compute the shortest path tree (SPT) based on link costs and build a routing table based on SPT. OSPF supports multiple equal-cost paths, load balancing, authentication, and various network types such as broadcast, point-to-point, point-to-multipoint, non-broadcast multi-access (NBMA), etc. OSPF is defined in RFC 2328 for IPv4 and RFC 5340 for IPv6. to use the IP address IP address Internet Protocol (IP) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. There are two versions of IP addresses: IPv4 and IPv6. IPv4 addresses are 32 bits long and written in dotted-decimal notation, such as 192.168.1.1. IPv6 addresses are 128 bits long and written in hexadecimal notation, such as 2001:db8::1. IP addresses can be either static (fixed) or dynamic (assigned by a DHCP server). 10.1.200.1 as the router ID Router ID (RID) Router ID (RID) is a unique identifier assigned to each router in a routing domain or protocol. RIDs are used by routing protocols such as OSPF, IS-IS, EIGRP, BGP, etc., to identify neighbors, exchange routing information, elect designated routers (DRs), etc.
RIDs are usually derived from one of the IP addresses configured on the router's interfaces or loopbacks, or manually specified by network administrators. RIDs must be unique within a routing domain or protocol instance. is that the loopback interface state Loopback interface Loopback interface is a virtual interface on a router that does not correspond to any physical port or connection. Loopback interfaces are used for various purposes such as testing network connectivity, providing stable router IDs for routing protocols, providing management access to routers, etc. Loopback interfaces have some advantages over physical interfaces such as being always up unless administratively shut down, being independent of any hardware failures or link failures, being able to assign any IP address regardless of subnetting constraints, etc. Loopback interfaces are usually numbered from zero (e.g., loopback0) upwards on routers. Loopback interfaces can also be created on PCs or servers for testing or configuration purposes using special IP addresses reserved for loopback testing (e.g., 127.x.x.x for IPv4 or ::1 for IPv6). Loopback interfaces are also known as virtual interfaces or dummy interfaces . Loopback interface state Loopback interface state refers to whether a loopback interface is up or down on a router . A loopback interface state can be either administratively controlled (by using commands such as no shutdown or shutdown ) or automatically determined by routing protocols (by using commands such as passive-interface or ip ospf network point-to-point ). A loopback interface state affects how routing protocols use the IP address assigned to the loopback interface for neighbor discovery , router ID selection , route advertisement , etc . A loopback interface state can also affect how other devices can access or ping the loopback interface . A loopback interface state can be checked by using commands such as show ip interfacebrief or show ip ospf neighbor . is independent of any physical interface and reduces routing updates.
The loopback interface state is independent of any physical interface because it does not depend on any hardware or link status. This means that the loopback interface state will always be up unless it is manually shut down by an administrator. This also means that the loopback interface state will not change due to any physical failures or link failures that may affect other interfaces on the router.
The loopback interface state reduces routing updates because it provides a stable router ID for OSPF that does not change due to any physical failures or link failures that may affect other interfaces on the router. This means that OSPF will not have to re-elect DRs Designated Routers (DRs) Designated Routers (DRs) are routers that are elected by OSPF routers in a broadcast or non-broadcast multi-access (NBMA) network to act as leaders and coordinators of OSPF operations in that network. DRs are responsible for generating link-state advertisements (LSAs) for the entire network segment, maintaining adjacencies with all other routers in the segment, and exchanging routing information with other DRs in different segments through backup designated routers (BDRs). DRs are elected based on their router priority values and router IDs . The highest priority router becomes the DR and the second highest priority router becomes the BDR . If there is a tie in priority values , then the highest router ID wins . DRs can be manually configured by setting the router priority value to 0 (which means ineligible) or 255 (which means always eligible) on specific interfaces . DRs can also be influenced by using commands such as ip ospf priority , ip ospf dr-delay , ip ospf network point-to-multipoint , etc . DRs can be verified by using commands such as show ip ospf neighbor , show ip ospf interface , show ip ospf database , etc . , recalculate SPT Shortest Path Tree (SPT) Shortest Path Tree (SPT) is a data structure that represents the shortest paths from a source node to all other nodes in a graph or network . SPT is used by link-state routing protocols such as OSPF and IS-IS to compute optimal routes based on link costs . SPT is built using Dijkstra's algorithm , which starts from the source node and iteratively adds nodes with the lowest cost paths to the tree until all nodes are included . SPT can be represented by a set of pointers from each node to its parent node in the tree , or by a set of next-hop addresses from each node to its destination node in the network . SPT can be updated by adding or removing nodes or links , or by changing link costs . SPT can be verified by using commands such as show ip route , show ip ospf database , show clns route , show clns database , etc . , or send LSAs Link-State Advertisements (LSAs) Link-State Advertisements (LSAs) are packets that contain information about the state and cost of links in a network segment . LSAs are generated and flooded by link-state routing protocols such as OSPF and IS-IS to exchange routing information with other routers in the same area or level . LSAs are used to build link-state databases (LSDBs) on each router , which store the complete topology of the network segment . LSAs are also used to compute shortest path trees (SPTs) on each router , which determine the optimal routes to all destinations in the network . LSAs have different types depending on their origin and scope , such as router LSAs , network LSAs , summary LSAs , external LSAs , etc . LSAs have different formats depending ontheir type and protocol version , but they usually contain fields such as LSA header , LSA type , LSA length , LSA age , LSA sequence number , LSA checksum , LSA body , etc . LSAs can be verified by using commands such as show ip ospf database , show clns database , debug ip ospf hello , debug clns hello , etc . due to changes in router IDs.
The other options are not reasons because:
The IP address associated with the loopback interface is non-routable and prevents loops: This option is false because the IP address associated with the loopback interface is routable and does not prevent loops. The IP address associated with the loopback interface can be any valid IP address that belongs to an existing subnet or a new subnet created specifically for loopbacks. The IP address associated with the loopback interface does not prevent loops because loops are caused by misconfigurations or failures in routing protocols or devices, not by IP addresses.
The loopback interface state is dependent on the management interface state and reduces routing updates: This option is false because the loopback interface state is independent of any physical interface state, including the management interface state Management interface Management interface is an interface on a device that provides access to management functions such as configuration, monitoring, troubleshooting, etc . Management interfaces can be physical ports such as console ports, Ethernet ports, USB ports, etc., or virtual ports such as Telnet sessions, SSH sessions, web sessions, etc . Management interfaces can use different protocols such as CLI Command-Line Interface (CLI) Command-Line Interface (CLI) is an interactive text-based user interface that allows users to communicate with devices using commands typed on a keyboard . CLI is one of the methods for accessing management functions on devices such as routers, switches, firewalls, servers, etc . CLI can use different protocols such as console port serial communication protocol Serial communication protocol Serial communication protocol is a method of transmitting data between devices using serial ports and cables . Serial communication protocol uses binary signals that represent bits (0s and 1s) and sends them one after another over a single wire . Serial communication protocol has advantages such as simplicity, low cost, long
