QUESTION 359
Which of the following descriptions about DIS in IS-IS is wrong?

In the IS-IS broadcast network, the election of DIS is preemptive mode

In the IS-IS broadcast network, routers with a priority of 0 also participate in the election of DIS

QUESTION 360
The first 4 bits of the IP multicast address are fixed 1110, corresponding to the upper 25 bits of the multicast MAC address. Of the last 28 bits of the IP multicast address, only 23 bits are mapped to the MAC address, so 5 bits of address information are lost. The direct result is that 32 IP multicast addresses are mapped to the same MAC address.

True

False

QUESTION 361
About the description of Network Address Port Translation (NAPT) and the Translate only network addresses (No-PAT), which of the following statement is true?

No-PAT supports protocol address translation at the network layer

No-PAT only supports protocol port conversion at the transport layer

After NATP translation, for external users, all messages will only come from the same 1P address

NAPT only supports protocol address translation at the network layer

QUESTION 362
Which of the following description about OSPF routing aggregation is wrong?

Any router in OSPF can perform route aggregation operations

Inter-area route aggregation refers to the aggregation of routing information of the same prefix, and only one route is advertised to other areas

OSPF has two route aggregation methods: ABR aggregation and ASBR aggregation

Through route aggregation, routing information can be reduced, thereby reducing the size of the routing table and improving the performance of the router

QUESTION 363
Which of the following descriptions about BGP Atonic_Aggregate and Aggregator are correct?
(Multiple choice)
