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?

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

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.

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

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.

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.

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.

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

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

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.

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.

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 at most the latest five reasons why a VXLAN tunnel goes Down.

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

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

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.

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

Inter-VPC traffic must pass through the firewall.

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.

Which of the following statements are true about a routing design that employs OSPF on the underlay network of a DC? (Select All that Apply)

Typically, the IP address of Loopback0 is configured as the VTEP IP address and the same IP address is planned for active-active leaf nodes in the same group.

The network type of spine and leaf nodes can be set to P2P in order to accelerate convergence.

Typically, the IP address of Loopback0 is configured as the VTEP IP address and the same IP address is planned for active-active leaf nodes in the same group.

The network type of spine and leaf nodes can be set to P2P in order to accelerate convergence.

This routing design is recommended when the DC has more than 300 switches.

It is recommended that all devices be planned in Area 0.

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

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

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.
