Huawei HCIE-Data Center Network (Written) V1.0 Sample Questions:

1. In the Multi-Site scenario of a CloudFabric solution, what are the correct items in the following description of Layer 2 interoperability?

A) In local VNI mode, the local VNI of the local Fabric GW is used as the outbound VXLAN packet to encapsulate VXLAN packets to the VNI
B) In practice, different sites have their own independent VNI space, so VXLAN tunnels inside different sites are likely to use different VNI C. Layer 2 interconnection is supported in two modes: local VNI and mapped VNI
C) In the mapped VNI mode, the Fabric GW at both ends uses BGP EVPN to negotiate a mapped VNI, and all packets sent to the peer end are routed using the mapped VNI VXLAN packing

2. Which of the following descriptions of underlay routing is wrong when deploying a data center network?

A) Compared with OSPF, EBGP has lower computational consumption and better scalability
B) OSPF is recommended for small and medium-sized data center networks, and EBGP is recommended for large and medium-sized networks
C) When EBGP is used for underlay routing, each group of active-active leaves is deployed on an AS
D) When OSPF is used for underlay routing, only single-region OSPF can be deployed

3. In which of the following scenarios would a physical hard disk be converted into a block device?

A) Virtual machines access remote centralized storage devices via FC-SCSI

A) The HPC cluster network adopts a planar design that considers the business plane, management plane, and computing plane separately
B) Both the high-performance computing network and the storage front-end network must be deployed independently to ensure high network performance and prevent mutual interference
C) The service management network is used for cluster management, resource monitoring, and other related business operations, and is usually deployed as a TCP/IP lossy network
D) High-performance computing networks are used for communication between computing nodes, requiring networks with low latency and high throughput, and are generally deployed as lossless networks
