NEW QUESTION 81
In what mode does an LWAPP-enabled access point operate?
- A. ad hoc mode
- B. autonomous mode
- C. lightweight mode
- D. WGB
Answer: C
Explanation:
Lightweight access point protocol (LWAPP)-enabled access points operate in lightweight mode. LWAPP is a protocol used to allow centralized management of APs. The management components are removed from the APs, and a WLAN controller provides a single point of management. This controller coordinates WLAN access, managing the load on the APs and user movement between APs. Upon starting, an LWAPP-enabled access point must obtain an IP address. It can then discover the controller using DHCP, DNS, or a subnet broadcast. When multiple wireless controllers are detected by an AP, it chooses to associate with the controller that has the fewest existing associated APs.
Individually configured APs that operate without central management are operating in autonomous mode. This would be the opposite of lightweight mode, which is made possible by LWAPP. Autonomous access points can be upgraded to lightweight. If they are upgraded, they will only function in conjunction with a WLAN controller.
Moreover, when an autonomous access point is upgraded to lightweight, the console port only provides read access to the unit.
Characteristics that autonomous and lightweight access points have in common:
Both support Power over Ethernet (PoE)
Both can use a Cisco Secure Access Control server (ACS) for security
A wireless gateway bridge (WGB) is used to connect a computer without a wireless network card to a wireless network, but not separate WLANs. The WGB can connect up to eight computers to a WLAN. The WGB connects to the root AP through a wireless interface.
Ad hoc is a WLAN mode used for peer-to-peer connectivity. Ad hoc mode allows wireless-enabled computers to communicate with each other without having an AP involved.

NEW QUESTION 82
Which of the following features does GLBP provide, but not HSRP and VRRP? (Choose all that apply.)
- A. Support for automatic load balancing
- B. Support for single active router
- C. Support for interface tracking
- D. Support for multiple gateways
Answer: A,D
Explanation:
Support for automatic load balancing and support for multiple gateways are two features that are provided by Gateway Load Balancing Protocol (GLBP) but not by Hot Standby Routing Protocol (HSRP) or Virtual Router Redundancy Protocol (VRRP).
GLBP, HSRP, and VRRP provide a redundant and fault-tolerant solution in case of first-hop router failure in a network. The basic operation of these three protocols is the same. In all three protocols, a group of routers on the same LAN is formed. One of the routers is selected as the active router and another as the standby router.
The router with the highest priority is automatically selected as the active router. If the active router fails, the standby router assumes the responsibilities of the active router. The role of the active router is to forward the packets from the hosts to the virtual router (default gateway).
GLBP provides automatic load balancing between multiple routers by configuring multiple MAC addresses but a single virtual IP address. Every active virtual forwarder (AVF) in the group is configured with the virtual IP address but with different MAC addresses. All such AVFs can then participate in the packet-forwarding process. Multiple gateways then can share the load. On the contrary, HSRP and VRRP do not support automatic load balancing. Both these protocols require additional configuration on all the routers that need to load balance. The additional configuration involves using multiple groups on the routers or assignment of different default gateways for the hosts.
Note that GLBP and VRRP are supported by both Cisco and non-Cisco routers, whereas, HSRP is supported only by Cisco routers.
Single active router and interface tracking both are supported by GLBP, HSRP, and VRRP.

NEW QUESTION 88
You have executed the following commands on switchA:
What is the result of executing the given commands? (Choose two.)
- A. AAA is not enabled on the switch
- B. Only the listed RADIUS server is used for authentication
- C. The key for the RADIUS server is firstKey111
- D. 802.1X authentication is enabled on the Fa0/1 interface only
Answer: B,C
Explanation:
A default list is used for the RADIUS server for authentication and the key for the RADIUS server is firstKey111. A RADIUS server combines the authentication and authorization processes. Before you configure the RADIUS server, you should enable AAA by using the aaa new-model command in the global configuration mode. Then, you can specify the location of the RADIUS server and the key using the radius-server host command. In this case, the RADIUS server is located at the IP address 192.168.105.67 and requires the key firstKey111 as the encryption key. This key must be mutually agreed upon by the server and the clients.
The aaa authentication dot1x default group radius command creates a method list for 802.1X authentication.
The default group radius keywords specify that the default method will be to use all listed RADIUS servers to authenticate clients. Since only one is listed, it will be the only one used.
It is incorrect to state that 802.1X authentication is enabled on the Fa0/1 interface only. The interface range Fa
0/1 - 11 and the dot1x port-control auto commands specify that 802.1X authentication is enabled on the interfaces Fa0/1 to Fa0/11.
It is incorrect to stat that AAA is not enabled on the switch. The aaa new-model command enables AAA globally on the switch.
