Question 1

Based on the multiple computing scenarios of Huawei' s CloudFabric intelligent lossless network solution, what are the correct descriptions of HPC cluster network design?

A : The HPC cluster network adopts a planar design that considers the business plane, management plane, and computing plane separately

B : 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

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 : 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

Answer: A,B,C

Question 2

Which of the following is wrong in the description of communication between VMs in a DVS distributed virtual switch environment in server virtualization?

A : VMs in the same port group, if they are on different hosts, can reach DVS on the destination host through the uplink of DVS and finally complete communication with the remote VM

B : VMs in different port groups (belonging to different VLANs) need to go through the uplink of the DVS to the physical switch, through which the VLAN is implemented Communications

C : VMs in the same port group, if they are in the same host, can communicate directly via DVS

D : VMs that are in different DVSs but belong to the same VLAN port group can communicate directly over DVS

Answer: D

VM;(2) iMaster NCE-Fabric obtains VM on-line information through VMM (3) The network administrator creates the corresponding virtual network through iMaster NCE-Fabric (4) iMaster NCE-Fabric senses the location of the VM and automatically delivers the mapping of VLAN and VNI

A : 1234

B : 3142

C : 4132

D : 3124

Answer: D

Question 4

B : Spine

C : Service Leaf

D : ServerLeaf

Answer: C

Question 5

What are the correct terms of the following description of the logical concepts of the CloudFabric solution iMasterNCEFabric?

A : Tenant: The basic unit of enterprise business management, and a tenant can only create one VPC

B : Logic Router: Used to connect VMs located on different networks, ensuring that VMs can communicate with other VMs across a three-layer network

C : Logic Switch: Used to connect different VMs to ensure that VMs can communicate with other VMs within the Layer 2 network

D : LoadPortVM is an access point into the network, and a physical port of a network device can be virtualized as multiple LoaicPorts

Answer: B,C,D
