Huawei HCSP-Presales-Data Center Network Planning and Design V1.0 Sample Questions:
1. (During data center network design, if the number of TOR switches is less than 100, which of the following protocols is recommended for underlay routing?)
A) BGP
B) RIP
C) OSPF
D) IS-IS
2. (What are the application scenarios of the overlay network?)
A) Network NFV cloud (network cloud and SDN + NFV)
B) Private cloud (converged resource pool deployment and data center integration)
C) Public cloud service (IaaS/PaaS/SaaS)
D) Hosting services in traditional IDCs
3. (Reliability design is important for the physical network design of a data center. Which of the following are true about reliability design principles?)
A) When modular switches are deployed on the network, the inter-card connection is recommended for uplinks and downlinks, stack link, and peer-link of modular switches to implement card-level reliability.
B) Server link reliability: One server is dual-homed to two server leaf nodes, and NICs on a server work in load balancing or active/standby mode. If one server link fails, services are switched to the redundant or standby link.
C) Uplink reliability of leaf nodes: ECMP is implemented between leaf and spine nodes through multiple links.
D) Peer-link fault: When the peer-link in an M-LAG fails, the DAD mechanism prevents dual master devices on the network and improves reliability.
4. Which of the following is not a characteristic of high-performance networks?
A) High throughput
B) Higher GPU computing power
C) Zero packet loss
D) Low latency
5. Which of the following is not an advantage of the spine-leaf networking over the traditional networking?
A) The flattened network features redundancy, reliability, and high throughput, facilitating east-west network capacity expansion.
B) Each leaf node is connected to one or two spine nodes to enable communication between all types of nodes connected to the network.
C) Resources are pooled between zones to avoid uneven resource distribution.
D) The logical two-layer architecture has a high oversubscription ratio.
