Question 522

What are the functions of an IGMPv2 Query message? (Choose three.)

A router sends IGMPv2 Query messages to collect group memberships of receiver hosts.

A router sends IGMPv2 Query messages to elect a querier.

If a router can periodically send IGMPv2 Query messages, it indicates that the router runs properly.

Based on IGMPv2 Query messages, receiver hosts can obtain the address of a querier and unicast Report messages to the querier.

Question 523

What are the differences between the IGMP versions? (Choose two.)

IGMPv1/v2 cannot elect queriers but IGMPv3 can.

In IGMPv2/v3, members can actively leave groups, whereas in IGMPv1 members cannot actively leave groups.

IGMPv1/v2 do not support the SSM model but IGMPv3 supports.

IGMPv1/v2 do not support group-specific Query messages but IGMPv3 supports.

Question 526

Which of the following statements about multicast MAC addresses are true? (Choose three.)

The high-order 24 bits of a multicast MAC address are 0x01005e and the low-order 23 bits of a multicast MAC address are the same as the low-order 23 bits of a multicast IP address.

One multicast MAC address maps 32 IP multicast addresses.

Multicast MAC addresses are used at the link layer to identify receivers that are in the same multicast group.

One multicast MAC address maps only one IP multicast address.

Question 527

IGMP interface group report information Ethernet6/1/1(40.1.1.1):

The preceding information shows the entry status of an IGMP interface on Ethernet 6/1/1 on a router.

Assume IGMP sends the group-and-source-specific Query message. Which of the following statements is true?

IGMP respectively sends two messages: The source carried in one of the messages is 20.1.1.56 with the S flag bit not set; the source carried in the other message is 20.1.1.57, with the S flag bit set to 1.

IGMP respectively sends two messages: The source carried in one of the messages is 20.1.1.56 with the S flag bit set to 1; the source carried in the other message is 20.1.1.57, with the S flag bit not set.

IGMP sends one message carrying two sources 20.1.1.56 and 20.1.1.57, with the S flag bit set to 1.

IGMP sends one message carrying two sources 20.1.1.56 and 20.1.1.57, with the S flag bit not set.
