Question 1

Which of the following statements about static VXLAN channel configuration are correct? (Multiple choice)

A. One NVE interface can be associated with multiple VNIs, so when there are multiple BDs, only one NVE interface can be created B. In the NVE interface, the destination address of the VXLAN tunnel can be specified by the address in the head-end copy list. Multiple VXLAN tunnels can only create one NVE interface C. A BD needs to create an NVE interface, when there are multiple BDs, multiple NVE interfaces must be created D. For a VXLAN tunnel, a one-to-one corresponding NVE interface needs to be created, in which the source IP address and destination IP address are clearly specified. Therefore, there are multiple VXLAN tunnels on VTEP. The corresponding number of NVE interfaces must be configured

Question 4

The following are the statements about LDP reliability, which one is wrong?

A. The association between the LDP and the IGP requires the IGP to suppress the advertisement of the route and ensure that the LDP path is consistent with the IGP path. B. LDP FRR can also be used to generate an LSP for the label mapping from the non-optimal next hop. And it can be as a backup of the primary LSP to establish the transfer entries. C. LDP GR Graceful Restart uses the feature that the MPLS forwarding plane is separated from the control plane. The device does not interrupt when the protocol is restarted or the active/standby switchover is performed. D. The manually configured LDP FRR policy defaults to a 32-bit backup route that triggers LDP to establish a backup LSP.

R2 specifies that the peer R1 sets the MED attribute to 150 in the export direction. D. R1 specifies that the peer R2 sets the local priority to 150 in the import direction.
