Questions # 61:

Which of the following descriptions of multivariate computation is wrong?

Options:

Multivariate computing can provide basic general-purpose computing, artificial intelligence computing, and high-performance computing, all of which need to be carried over lossless networks

The basic computing power corresponding to the basic general technology mainly refers to the computing power provided by the server based on the CPU chip

The intelligent AI computing power corresponding to AI computing mainly refers to the computing power provided by accelerated computing platforms based on chips such as CPUs, NPUs, and FPGA ASICs to provide AI training and inference

The supercomputing power corresponding to high-performance computing mainly refers to the computing power provided by high-performance computing clusters such as supercomputers

Answer

Questions # 62:

When iMaster NCE-Fabric performs a multipath probe and the result is "Timeout", which of the following is the meaning of the representation?

Options:

Indicates that the network between the source node and the destination node is unreachable, resulting in the failure to execute the detection task

The probe cannot be executed because the source node cannot be found

Indicates that the probe is successful and the path is normal

Indicates that the probe task has been executed, but the packet forwarding fails due to incomplete or interrupted routes

Answer

Questions # 63:

How many queues does PFC support in total?

Options:

Answer

Questions # 64:

In the computing linkage scenario of the CloudFabric solution, when the VM is wired, iMasterNCEFabric senses the port on which of the host connects to the leaf point through which of the following protocols? ?

Options:

LLDP

NETCONF

HTTP

gRPC

Answer

Questions # 65:

Which of the following describes the error in the CloudFabric network virtualization scenario?

Options:

Network administrators control the network through iMaster NCE-Fabric

When the compute administrator creates the VM, select the PortGroup for the corresponding network

Compute administrators manage compute resources through VMM

iMaster NCE-Fabric obtains the connection between the host and the TOR port through VMM

Answer

Questions # 66:

Which of the following is the role of SI in the NSH service chain?

Options:

The path number of the service chain

Used to indicate the next-hop IP address

Used to prevent loops

The SI value can be used to calculate the number of business function points that are currently eclips

Answer

Explanation

Analysis: SI:service index, the service function index, which can be used to calculate the current number of business function points through the SI value

Questions # 67:

There are three main ways to achieve I virtualization: full virtualization, paravirtualization, and hardware-assisted virtualization. The following description of 1/O anthropomorphism, what are the correct terms?

Options:

Full virtualization: Completely use software to emulate real hardware, such as a keyboard and mouse

Paravirtualization: Introduce a privileged virtual machine (Doman0) to run the hardware driver, and the rest of the GuestOS is accessed by 1/0 devices through the privileged virtual machine

Hardware-Assisted Virtualization: The 1/O device driver is installed directly in the virtual machine operating system and can be used without any modification to the operating system

Compared with para-virtualization and hardware-assisted virtualization, full virtualization has the lowest latency and the best performance

Answer

A, B, C

Questions # 68:

In a data center network, which of the following technologies is required to enable virtual machine traffic to access the VAS services provided by FW and LB in turn according to a specific path?

Options:

Security group

EIP

Microsegmentation

Business chain

Answer

Explanation

Analysis: A business chain is a technology that provides orderly services to the application layer. By defining the service chain path, you can make the matching traffic pass through the specified VAS devices (such as firewall, load balancer, in-depth inspection, intrusion prevention, etc.) in turn, so as to obtain the corresponding value-added services in turn. The use of service chains helps to use the same network to provide differentiated value-added services for different services, and the orchestration of service chains through the controller can quickly set the traffic path when customer services are delivered to meet the network function requirements of customer services.

Questions # 69:

Which of the following data center deployment scenarios is typically used to achieve business continuity and ensure uninterrupted service to users in the event of a failure?

Options:

Intra-city active-active

Two places and three centers

Edge DC

Hybrid cloud

Answer

A, B, D

Questions # 70:

Which of the following is NOT a core component of Kubernetes?

Options:

LoadBalancer

kubelet

etcd

API Server

Answer

Explanation

Analysis: API Server: The Kubernetes cluster management portal is the only entry for adding, deleting, modifying, and querying all Kubernetes resources, and is the central hub for data interaction and communication between various functional modules in the cluster. Northbound can provide Kubernetes cluster management through REST API, Kubernetes UI, and Kubectl CLI . etcD.A distributed key-value database used to store the metadata of Kubernetes clusters, such as the names and addresses of Kubernetes nodes, and pods IP, service IP, and Layer 4 ports, among others. kubelet: The kubelet is deployed on each node and dynamically creates and deletes pods on the node by listening to the Kubernetes API Server and periodically report the resource usage of the node to the API server.
