Question 645

The first four bits of a multicast IP address are fixed as 1110 and are mapped to the most significant 25 bits of a multicast MAC address.

Among the last 28 bits of a multicast IP address, only 23 bits are mapped to a multicast MAC address, and information about the other 5 bits is lost. As a result, 32 multicast IP addresses are mapped to the same MAC address.

Question 648

Which of the following statements regarding routing policy and policy-based routing are true? (Choose all that apply.)

Policy-based routing is used to control packet forwarding without following routes in the routing table.

A routing policy is used to control import, advertisement, and receiving of routing information.

A routing policy is used to control packet forwarding without following routes in the routing table.

Policy-based routing is used to control import, advertisement, and receiving of routing information.

Question 649

Which of the following statements regarding LACP are true? (Choose all that apply.)

LACP is based on IEEE802.3au.

The local device sends LACPDUs to exchange information with the remote end.

Devices at both ends determine the Active side based on the LACP system priority and system ID.

Devices at both ends determine active interfaces based on the LACP priority and ID of the interface on the passive side.

Question 650

Which of the following statements regarding preemption in static LACP mode are true? (Choose all that apply.)

Preemption in static LACP mode is enabled by default.

When a high-priority interface switches to the inactive interface due to a fault and then is restored, if preemption is enabled, the restored high-priority interface becomes the active interface after a delay. If preemption is disabled, theinterface cannot become the active interface.

To prevent unstable transmission due to frequent link status changes, can set a preemption delay.

If the preemption delays at both ends are different, the larger preemption delay is used.
