Question 1

The correct statement about the IGMP proxy is ? Multi-select

AThe downstream interface of the IGMP proxy device generates multicast relay table items

BIGMP proxy can detect the link status with the linkage through the information of the member host joining/leaving the multicast group, and realize the rapid switching of the primary and standby device links

CIGMP proxy is typically deployed on devices between hosts that are members of the access device
The

DIGMP proxy device cannot send query messages to downstream member hosts in place of the IGMP queryer to maintain group membership

Answer : A, B, C

Question 4

As shown in the figure, as shown, as the AS10 has two paths to access THEA1, the optimal route passed from the 4S23 by default is now sprinkled with S00 to ass4O The odds belt wins even more worrying. Therefore, in the R2 configuration as follows, after the completion of the coordination, it is found that the most worrying route has not changed, and some operations can be adjusted to make the configuration

Question 5

If a DR needs to be elected between multicast routers running PIM-SM to be responsible for the sending and receiving of source or member multicast data, which one is described correctly below for the DR election rule?

APIM routers with long interface masks are elected dr.

BCompare the DR priority first; With the same priority, you need to compare the interface IP addresses of the PIM routers to elect dr

CPIM routers with small IP addresses are elected DR. PIM routers with low D. DR priority values are elected DR.

Answer : B
