Huawei H19-402_V1.0 Exam Syllabus Topics:

Huawei HCSP-Presales-Data Center Network Planning and Design V1.0 Sample Questions:

1. Incast traffic in distributed AI computing and in the distributed storage architecture are prone to cause network congestion.

A) FALSE
B) TRUE

2. RoCEv2 is implemented based on TCP.

A) FALSE
B) TRUE

3. (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) OSPF
B) IS-IS
C) RIP
D) BGP

4. Which of the following are characteristics of distributed VXLAN gateways?

A) A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.
B) The number of ARP entries supported is a bottleneck. A single Layer 3 gateway is used. For tenants whose traffic is forwarded by the Layer 3 gateway, ARP entries must be generated for the tenants on the Layer 3 gateway, but only a limited number of ARP entries are allowed by the Layer 3 gateway, which impedes data center network expansion.
C) A distributed VXLAN gateway (leaf node) only needs to learn the ARP entries of servers connected to it, whereas a centralized Layer 3 VXLAN gateway needs to learn the ARP entries of all servers on a network. Therefore, the number of ARP entries supported is no longer a bottleneck on distributed VXLAN gateways, and the network scalability is improved.
D) Forwarding paths are not optimal. Inter-subnet Layer 3 traffic between devices connected to the same gateway in a data center must be transmitted to a unified Layer 3 gateway for forwarding.

5. Tenants apply for data center network, storage, and compute resources. One department can be regarded as one tenant, so an enterprise has multiple tenants, and the enterprise ' s data center can be managed by one tenant administrator.

A) FALSE
B) TRUE
