A. MPI_Gather B. MPI_Scatter C. MPI_AllReduce D. P2P

Correct Answer: A,B,C

Question 3

Which of the following is not supported by iMaster NCE-FabricInsight MDA in a multi-cloud and multi-DC scenario?

A. Cross-DC network health assessments B. Visibility of cross-DC application access traffic C. Visibility of traffic to and from each other across DC networks D. Unified configuration across DC underlay networks

Correct Answer: D

Question 4

When a Huawei switch enables any of the following functions, it can quickly manage and control access hosts?

A. NPCC B. AI ECN C. IQCN D. INOF

Correct Answer: D

Question 5

Which of the following components does not typically include in the control node of open source OpenStack?

A. Keystone B. Cinder C. Nova D. Horizon

Correct Answer: B

Question 6

What are the correct descriptions of VAS service provisioning in the network virtualization scenario of Huawei CloudFabric Solution?

A. IMaster NCE-Fabric supports the delivery of route configuration from the Fabric network to the VAS side, regardless of whether the VAS is managed by the controller or not B. IMaster NCE-Fabric supports route configuration and VAS service delivery from Huawei VAS to Fabric network C. IMaster NCE-Fabric supports business automation orchestration of third-party VAS, as long as the VAS is within the scope of the controller D.

Question 7

What are the correct items in the following description of lossless network architecture design in multivariate computing scenarios?

A. In the case of a two-level network, the Spine switch does not have an uplink interface, and all ports are used to connect to the Leaf switch B. First, the total number of network access interfaces is determined according to the number of computing nodes in the cluster and the number of service interfaces of each node C. When designing a network architecture, a bottom-up approach is generally used to determine how many layers of architecture to use based on the size of the network D. In two-tier networking, the number of Spine switches is equal to the total number of upstream interfaces of all leaf switches divided by the number of interfaces per Spine switch and rounded up by D

Question 8

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?

A. Microsegmentation B. EIP C. Business chain D. Security group

Question 9

In the container network scenario of the CloudFabric solution, when the container L3 is connected, the calico CNI plug-in does not need to configure which parameters of the container NIC?

A. MAC B. routing C. VLAN D. IP

Correct Answer: C

Question 10

Which of the following descriptions of VNI in a VXLAN network is correct?

A. L3 VNI is associated with a VPN instance to forward VXLAN packets across subnets, and VPIN instances associated with different L3 VNIs only need to be RT Values can be matched to achieve interoperability B. A tenant can have one or more VNIs with a VNI length of 16 bits, supporting millions of tenants C. L2 VNI is used to forward VXLAN packets on the same subnet, and different BDs can also use the same L2 VNI to achieve Layer 2 communication on VXLAN networks. All VXLAN packets carry both L2 VNI and L3 VNI

Correct Answer: C

Question 11

Which of the following components of open-source OpenStack provides a Dashboard for users to use?

A. Keystone B. Cinder C. Heat D. Horizon

Correct Answer: D

Question 12

Which of the following descriptions of data center interconnection solutions is wrong?

A. After a VXLAN is established in the local mode in the segment VXLAN mode, packets are encapsulated with the local DCILeaf when they arrive at the local DCI Leat and are sent to the peer DCI Leat VNI, not the VNI of the peer DCI Leaf B. The VLAN hand-off mode enables L2 communication between data centers C. The E2E EVPNVXLAN mode directly establishes a VXLAN tunnel between the VTEPs in two data centers D. In SegmentVXLAN mode, EVPN routes are transmitted in a three-stage mode to implement L3 communication between data centers

Correct Answer: A

Question 13

Device configuration parameters can be adjusted when using the edge intelligence function of iMaster NCE-FabricInsight for specified stream analysis. Which of the following device configurations cannot be automatically delivered during UDP specified stream analysis?

A. Whether to match TAG packets with a layer 1 VLAN B. Whether the VXLAN packet is matched C. Active aging time D. ACL Number

Correct Answer: C
