Which of the following statements is false about VXLAN gateways?

A. A Layer 2 VXLAN gateway forwards traffic to a VXLAN network or is used a for intra-subnet communication on the same VXLAN network.
B. A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.
C. Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
D. A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and allows access to external networks (non-VXLAN networks).

QUESTION 25
Which of the following modes can be configured for Eth-Trunk interfaces on Huawei data center switches?

A. LLDP mode
B. M-LAG mode
C. LACP mode
D. Manual mode

Correct Answer: CD
QUESTION 26
In an M-LAG, the default priority of a device for DFS group master/backup negotiation is .(Enter only digits.)
Correct Answer: 32768
QUESTION 27
Both M-LAG and stacking technologies can overcome the disadvantages of traditional DCNs. However, M-LAG is a better choice to ensure 24/7 service continuity.

A. TRUE
B. FALSE

Correct Answer: A
QUESTION 28
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?

A. If Type 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.
B. If Type 2 configurations of the two M-LAG member devices are inconsistent, an alarm that indicates key and common configuration inconsistencies is generated.
C. If Type 2 configurations of the two M-LAG member devices are inconsistent, the M-LAG running status may be abnormal. Compared with Type configuration problems, Type 2 configuration problems are more likely to be detected and have less impact on the network.
D. 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 configurations on the two devices are inconsistent.

Correct Answer: B
QUESTION 29
WWhich of the following statements is false about M-LAG application scenarios on CE series switches?

A. Multi-level M-LAG can be configured in root bridge mode, simplifying networking and allowing more servers to be dual-homed to a network.
B. M-LAG mainly applies to scenarios where a server or switch is dual-homed to an Ethernet, VXLAN, or IP network.
C. The link utilization is low when a switch is connected to a network and a loop prevention protocol (such as MSTP) is deployed. In contrast, a switch can be dual homed to a network through M-LAG, implementing load balancing.
D. The configuration for dual-homing a server to switches is the same as that for common link aggregation. Ensure that the server and switches use the same link aggregation mode. It is recommended that the LACP mode be configured on both ends.

Correct Answer: A
QUESTION 30
Which of the following statements are true about deploying a loop-free M-LAG network in root bridge mode?

A. You need to disable STP on peer-link interfaces.
B. You need to manually configure the two M-LAG member devices as root bridges and configure the same bridge ID for them.
C. This network is applicable to single-level M-LAG deployment
D. Only MSTP is supported.

Correct Answer: ABC
