Question #1

Which of the following statements about the intercommunication between Sub VLANs in Super VLAN technology is correct?

A. The host IP addresses in different Sub VLANs belong to the same network segment, but due to the isolation of Sub VLAN, the Sub VLANs cannot communicate with each other.

B. Hosts in different Sub VLANs are isolated at Layer 2, and can communicate at Layer 3 through the local proxy ARP technology of the Super VLAN interface.

C. Hosts in different Sub VLANs are isolated at Layer 2, and can communicate at Layer 3 through the common proxy ARP technology of the Super VLAN interface.

D. The host IP addresses in different Sub VLANs belong to the same network segment, and they can communicate directly with each other through Layer 2 forwarding.

Question #5

Which of the following statements about the PIM SM joining process is correct? (Multiple choice)

A. When there are no receivers of multicast group G locally in the DR, the DR will send a prune message to the upstream router.

B. Both PIMSM and PIM DM have pruning veto processes

Question #8

Which of the following about IGMP Snooping is correct? (Multiple choice)

A. You can configure both IGMP and IGMP Snooping in the same VLAN.

B. Port fast leave means that when the switch receives an IGMP Leave message, it directly deletes the port from the corresponding forwarding table entry's outbound port list

C. Enabling IGMP Snooping on a Layer 2 device will allow you to create and maintain multicast forwarding entries at the data link layer, thereby forwarding multicast data normally at the data link layer.

D. You can enable the unknown multicast group discard function on the switch. When the switch receives an unknown multicast data packet, it only forwards it to its router port and does not broadcast it within the VLAN.
