NEW QUESTION 12
Which of the following statements is false about the overlay technology and VXLAN protocol?

A VXLAN tunnel endpoint that performs encapsulation is called a VNI.

VXLAN uses ECMP of the underlay network to improve network forwarding performance.

A VXLAN network is built based on UDP.

VXLAN expands the number of subnets to 16 million and supports multi-tenancy.

NEW QUESTION 13
Which of the following issues can be identified by the health function of iMaster NCE-FabricInsight? (Select All that Apply)

Switch ARP entry threshold exceeded

OSPF router ID conflict

Switch CPU usage threshold exceeded

Routing loop on the network

NEW QUESTION 14
Which of the following O&M functions are supported in Huawei CloudFabric Solution? (Select All that Apply)

Multi-path detection

Network connectivity detection, such as IP ping and MAC ping

Single-path detection

Visualization of entries (MAC/IP) on logical routers and switches

NEW QUESTION 15
iMaster NCE-Fabric is Huawei’s DC controller. Tenants can use it to create VPCs and deploy logical networks as required. After logical NEs are deployed, the corresponding network configurations are delivered to underlying network devices. Which of the following statements is false about the delivered network configurations?

Logical switches are mainly used for Layer 3 communication between hosts on a VXLAN network. These switches correspond to Layer 3 gateway configurations such as VBDIF interface and VPN instance configurations on physical devices.

An end port represents an online host. It corresponds to the traffic encapsulation type (whether a VLAN tag is carried) configured on a Layer 2 sub-interface of a physical device.

A logical port is equivalent to an independent physical port that is used by a host to connect to a VXLAN network. It corresponds to the Layer 2 sub-interface configuration on a physical device.

Logical switches are mainly used for Layer 2 communication between hosts on a VXLAN network. These switches correspond to BD and Layer 2 VNI configurations on physical devices.

NEW QUESTION 16
Which of the following technologies are open-source virtualization technologies? (Select All that Apply)

Hyper-V

Xen

FusionSphere

KVM

NEW QUESTION 17
Which of the following statements are false about heartbeat link faults in an M-LAG? (Select All that Apply)

The fault that two master devices exist cannot be detected in the case of a peer-link fault.

An alarm is triggered.

The fault protection mechanism is triggered.

Services are affected.

NEW QUESTION 18
Which of the following are advantages of iMaster NCE-FabricInsight’s telemetry-based performance metric collection? (Select All that Apply)

Efficient transmission

Quasi-real-time data collection

Intelligent data analysis and automated troubleshooting

One-off subscription and continuous data push

NEW QUESTION 19
Linux consists of the user space and kernel space. Which of the following functions are included in the kernel space? (Select All that Apply)

The NIC driver sends data frames.

Data encapsulation

Bit stream transmission

Data encryption

NEW QUESTION 20
An enterprise builds a DC and deploys iMaster NCE-Fabric to automatically deliver network configurations. After the engineer manually deploys the underlay network and delivers overlay network configurations through iMaster NCE-Fabric, it is found that tenant hosts cannot access external networks. Which of the following is not a possible cause of this fault?

No return route is configured on the PE.

The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model.

No firewall security policy is configured when host traffic passes through the firewall.

The MAC address of the NVE interface on the VXLAN network is not manually specified.

NEW QUESTION 21
In the spine-leaf DCN architecture, the border leaf node and service leaf node can be deployed on the same device.

TRUE

FALSE

NEW QUESTION 22
Which of the following statements is false about VM service traffic in the computing scenario?

Traffic inside a fabric is VXLAN encapsulated.

Inter-VPC traffic must pass through the firewall.

Traffic between VAS devices and service leaf nodes is VLAN encapsulated.

Traffic between vSwitches on virtual servers and server leaf nodes is VLAN encapsulated.

NEW QUESTION 23
Which of the following statements is false about the routing design for the underlay network during DCN deployment?

OSPF is recommended for small and midsize DCNs, and EBGP is recommended for large and midsize networks.

When OSPF is used on the underlay network, only single-area OSPF can be deployed.

Compared with OSPF, EBGP involves fewer calculations and offers better scalability.

When EBGP is used on the underlay network, each group of active-active leaf nodes is deployed in an AS.

NEW QUESTION 24
In Huawei CloudFabric Solution, OSPF or BGP can be used on the underlay network of a DC.

TRUE

FALSE

NEW QUESTION 25
When an SDN controller cluster is deployed in Huawei CloudFabric Solution, which of the following network planes are divided based on carried services? (Select All that Apply)
