Which of the following statements are true about NSAP addresses

A. Area address and SystemID are fixed length, NSEL is variable length B. NSAP address and SystemID and NSEL three parts C. NSAP is equivalent to the IP address and protocol number in the IP network.

QUESTION NO: 3
Running the command on the router and its display information is as follows:
<RTA>displaisis peer
Peer information for ISIS(1)
----------------------------
Stem Id: 2222.2222.2222
Interface: Eth0/0 Circuit Id:
State: Up HoldTime: 27s Tpe: L1 PRI: 16
Stem Id: 3333.3333.3333
Interface: Tun3 Circuit Id:
State: Up HoldTime: 25s Tpe: L2 PRI: --
From the above information, we can know that RTA______.

A. is a Level-1-2 router B. The port type connected to the neighbor whose Stem-ID is 2222.2222.2222 is LAN C. is a Level-2 router D. The ports connected to both neighbors are not of type LAN

Correct Answer: A,B

QUESTION NO: 5
K As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; RTA, RTB, and RTD run OSPF process 200. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 to 190 on RTA and RTB, and import an external route 172.16.1.0/24 to OSPF100 on RTC. Both RTA and RTB are set to re-import the routes of OSPF100 to OSPF200.
According to the above scenario analysis, the following description about RTD learning external route 172.16.1.0/24 is correct ______.

A. There are two equal-cost routes to 172.16.10.0/24 on RTD, and the next hop points to RTA and RTB respectively B. There is a route to 172.16.10.0/24 on RTD, the next hop must point to RTA C. Route 172.16.10.0/24 could not be learned on RTD D. There is a route to 172.16.10.0/24 on RTD, the next hop may point to RTA or RTB

Correct Answer: D

QUESTION NO: 6
The disadvantage of Z routers using the Ethernet MAC address to generate the NET address of the IS-IS process is ________.

A. MAC addresses are not necessarily related to network planning, and MAC addresses are not easy to remember B. MAC addresses are not global, and management is inconvenient C. The MAC address and the Stem-ID in the NET have the same length, which is easy to confuse

Correct Answer: A,B

QUESTION NO: 7

The router ID of the neighbor router in OSPF process 1 of RTA is 3.3.3.3 D. RTA is elected as DR on the interconnected network

Correct Answer: B,C

QUESTION NO: 9
