Question 4

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

Options :

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 5

Which of the following descriptions of firewalls is wrong when deploying a data center network?

Options :

A :

After different security zones are divided on the firewall, the different security zones are isolated by default

B :

Firewalls can be deployed alongside Border Leaf to control secure access to incoming and outgoing traffic

C : The firewall can be managed through SecoManager, but the service needs to be configured manually

D : Firewalls can be deployed in active and standby image mode to enhance reliability

Answer: C
