Question 563

The following statement about static VXLAN tunnel configuration is correct?

A BD needs to create an NVE country, and when there are multiple BDs, multiple NVE interfaces must be created

An NVE interface can be associated with multiple VNls, so you can create only one NVE interface when there are multiple BDs

For a VXLAN tunnel, you need to create a corresponding NVE interface, in which you explicitly specify the source IP address and the destination IP address , so there are multiple VXLAN tunnels on the VTEP that must be vE interfacesThe destination address of the VXLAN tunnel is specified in the

NVE interface, and multiple VXLAN tunnels can create only one NVE interface

Question 564

How do IGMPv2 routers maintain cinderband group membership? Multi-select

The router queries a specific group

The router maintains a timeout timer for each group membership, refreshes the timer if the receiver host is received, and deletes the group membership if the timer times out

The router periodically sends a Query message, and after the receiver host receives the Query message, it reports a Report message

As soon as the leave message is received, the router immediately deletes the group membership

Question 566

The following statement about IPSec VPN is correct ?qo

Two routers establish an IPSec VPN in brutal mode, so that the two devices can interact with a minimum of 4 messages to establish a tunnel.

Brutal mode can support NAT traversal, while main mode does not support NAT traversal.

The two routers can establish OSPF neighbor relations and exchange intranet routes through the IPSec VPN tunnel

The two routers establish IPSecVPN in main mode, and from the 5th packet (included), the payload's data will be encrypted.

Question 567

During isis ' broadcast network database synchronization, is the following statement correct?

R2, as DIS, sends CSNP periodically.

R2 As DIS, Hello time is 3 times that of a normal router . C. R2 as DIS does not receive PSNP nouns for other routes.

RI and R3 maintain database consistency by periodically sending PSNP requests.
