Question # 1

After a CloudFabric data center network changes its services, which of the following functions can be used to compare the change results with user intent with the help of iMaster NCE-FabricInsight?

Data plane intent verification

Network health

Device snapshot comparison

Network snapshot comparison

Question # 2

Which of the following options is a software platform in the HPC scenario of Huawei ' s CloudFabric solution ?

Compiler

Scheduler

Math Library

Operating System

Question # 3

There are different scenarios for the service orchestration of the data center overlay network, which of the following scenarios needs to be unified through the cloud platform to realize the virtualization and resource pooling of computing, storage, and network resources in the DC?

Cloud-network integration scenario

Container network scenario

Rack rental scenario

Calculate the linkage scenario

Question # 4

In the process of open and programmable evolution of CloudFabric network services, APIs evolve from atomic APIs to network service APIs and then to intent APIs Which of the following is a web service API?

RESTful API

RESFCONF API

NETCONF API

Service Chain API

Question # 5

Which of the following RDMA networks can implement RDMA across network segments over Ethernet

InfiniBand

RoCE v1

RoCE v2

iWARP

Question # 6

In Huawei ' s CloudFabric solution, tenants are performing VPC interconnection service orchestration

When the virtual firewalls of two VPCs are distributed on two different physical firewalls, and traffic passes through the firewalls on both sides, and the two physical firewalls are connected to different service leaves, you need to create two different VRFs

When two VPCs have their own virtual firewalls and traffic crosses the firewalls, and the service leaves of the two WCs are the same, and if they share a physical firewall, you need to create two different VRFs

In all VPC interworking scenarios, if a meso-VRF is used, the VPC inter-communication will share a single interworking VRF, and the controller will not create two different interworking VRFs

When the virtual firewalls of two VPCs are distributed on two different physical firewalls, and traffic passes through the firewalls on both sides, and two physical firewalls are connected to the same service leaf, two different VRFs need to be created

Question # 7

In Huawei ' s CloudFabric solution, in the scenario where the Border Leaf and Service Leaf are separated, what are the correct descriptions of the following principles for traffic orchestration between internal and external networks?

The controller creates the corresponding tenant VRF and egress VRF on the Border Leaf based on the tenant network and the external network

The route to the external network on the border leaf is delivered by the iMaster NCE-Fabric controller, and only static routes can be delivered to connect with the external network

The controller creates the corresponding tenant VRF and egress VRF on the Service Leaf based on the tenant network and the external network

The backhaul route from the external network to the tenant network needs to be configured by the external network and cannot be delivered by the iMaster NCE-Fabric controller

Question # 8

As shown in the diagram, when DCs are interconnected via VLAN Hand-off, which of the following describes the error?

DCI-GW requires VXLAN support

DCI-GW does not learn the routes between the service host and the network

Transmission of common VLAN packets between the Fabric-GW and the DCI-GW

The DCI network only passes the underlay route for the DCI-GW

Question # 9

What is correct about the following description of Docker?

Image in Docker can be regarded as a special file system, which only provides the programs required by the container runtime, and the libraries, resources, configurations, and other files required by the container runtime are hosted by the host Machine OS provides

The Docker engine obtains the image from the repository and runs the container on the corresponding host

Image files are stored centrally in a repository and can be public or private

Docker containers are created based on images, and a running container is a process running on a Docker host
