Which statements regarding the PVID on the access interface are true? (Choose three.)

If a packet without VLAN tag is received, the interface adds a VLAN tag to the packets and sets the VID as the default VLAN ID.

If a packet with VLAN tag is received, the interface compares the VLAN ID in the tag with the default VLAN ID. If they are the same, the interface forwards the packets; otherwise, the interface discards the packets.

When the interface sends a packet with a VLAN tag that contains the default VLAN ID, the system removes the VLAN tag of the packet, and then forwards the packet.

How does an IGMP router maintain group memberships on the network? (Choose two.)

The router maintains a timer for each group membership. If the router receives a Report message from a receiver host, it refreshes the timer of the group membership of this host; if the router does not receive any Report message from areceiver host before the timer expires, it deletes the group membership of this host.

The router periodically sends Query messages. After a receiver host receives the Query message, the receiver host sends a Report message.
