4788

Question 9 of 20

10. Which of the following statements is false about centralized gateway deployment using BGP EVPN?

When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD.

A VXLAN tunnel is identified by a pair of VTEP IP addresses and can be established if the local and remote VTEP IP addresses are reachable to each other at Layer 3.

When BGP EVPN is used to dynamically establish a VXLAN tunnel, the local and remote VTEPs first establish a BGP EVPN peer relationship and then exchange BGP EVPN routes to transmit VNI and VTEP IP address information. A VXLAN tunnel is then dynamically established between them.

When configuring a VTEP, you need to create an EVPN Instance in the Layer 2 BD and configure an RD for the local EVPN instance. You do not need to configure an RT.

Question 10 of 20

11. 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.

Question 11 of 20

12. Which of the following statements is false about VXLAN tunnel establishment?

A VXLAN tunnel is identified by a pair of VTEPs.

After a tunnel is established, if one end of the tunnel goes Down, the other end may not go Down.

For a static tunnel, you need to manually configure the local and remote VNIs.

Dynamic tunnels depend on EVPN Type 5 routes to transmit information.

Question 12 of 20

13. Assume that a VXLAN tunnel is monitored on a Huawei CE series switch and that the tunnel status is Down or the tunnel fails to be dynamically established.
In this scenario, which of the following statements are true about how to check the cause of the fault? (Select All that Apply)

Run the display vxlan statistics command to check the cause of the fault.

Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel.

Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel.

Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down.

Question 13 of 20

14. Which of the following statements is false about M-LAG deployment?

Multi-level M-LAG is mainly used to construct a large Layer 2 network in a DCN or directly connect DCNs at Layer 2.

In multi-level M-LAG networking, you can manually configure the root bridge to prevent STP loops.

Multi-level M-LAG must be configured based on V-STP.

M-LAG networking can be classified into single-level M-LAG networking and multi-level M-LAG networking.

Question 14 of 20

15. After an M-LAG works properly, the two member devices synchronize information with each other in real time.
Which of the following pieces of information are synchronized between devices? (Select All that Apply)

ACL information

STP status

Device name

LACP information

Question 15 of 20

16. M-LAG configuration consistency check classifies device configurations into key configurations (Type 1) and common configurations (Type 2). This check can be performed in strict or loose mode based on the processing mode when key configurations are inconsistent.
Which of the following statements is false about M-LAG configuration consistency check?

In loose mode, if Type 1 configurations of the two M-LAG member devices are inconsistent, the member interface on the M-LAG backup device is in Error-Down state and an alarm is generated, indicating that Type 1 configurations on the two devices are inconsistent.

If Type 1 configurations of the two M-LAG member devices are inconsistent, certain problems may occur, such as loops and long-period packet loss when the status is normal.

If Type 2 configurations of the two M-LAG member devices are inconsistent, the M-LAG running status may be abnormal. Compared with Type 1 configuration problems, Type 2 configuration problems are more likely to be detected and have less impact on the network.

If Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated.

Question 16 of 20

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.

Question 17 of 20

18. Which of the following statements are true about the tenant service model? (Select All that Apply)

A tenant can apply for independent compute, storage, and network resources.

One logical router is mapped to one VRF.

An EPG can have only one subnet.

A subnet supports the access of only one VM.

Question 18 of 20

19. How many rollback levels does Huawei's iMaster NCE-Fabric support?

Question 19 of 20

20. Which of the following protocols is used to back up session tables between the active and standby firewalls in the hot standby scenario?

VRRP

BFD

HRP
