Question 1

The correct description of the extended features of ISIS is?

A. When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information. B. ISIS can choose whether to authenticate incoming SNP and LSP packets C. After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process. D. If there are other vendors' devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors' devices.

Correct Answer: A,B,D

Question 5

To implement the traffic filtering function, you can use trapp-filter or MQC, which can be called in more views than traffic-filter

A. FALSE B. TRUE

Correct Answer: B

Question 6

There is an As-path-filter.ip as-path-filter 1 permit*(100l400) $, which As-path-filter can match which of the following AS_PATH Attribute? (Confirmed).

A. 300 4200 B. 1234 1400 C. 3100 D. 100

Correct Answer: B,C,D

Question 7

Router HW1 exists in the carrier HW's network as an MPLSLSR router. The router receives a packet carrying a label, but the label entry does not exist in its LFIB.
So how does the router handle that message?

A. Router HW1 will forward the message with the default label B. Router HW1 drops the message C. Router HW1 uses LDP to create an LSP and creates a new path in LFIB for the label carried in the message D. Router HW1 strips off the label and looks for the FIB using the P destination address

Correct Answer: B

Question 8

Router RL runs the OSPF protocol and uses the display ip routing-tabe command to view the router RL's routing table, the following information about OSPF in the routing table is described correctly as?

A. In the routing table, the routing table entries identified by the OSPF identifier can only be learned through the 3 types of LSAs to B. In the routing table, Route table entries identified with the "O_ASE identifier can only be learned through routing introduction C. In the routing table, used. The 'OSPF' identifier identifies a route table entry that can only pass a Type 1 LSA D. In the routing table, the routing table entries identified with the 'OSPF identifier' can be learned through the 1/2/3/5 LSA to

Correct Answer: B

Question 9

Without dividing the zone, is the following description of the link state routing protocol correct?

A. Each router establishes a topology for the entire floodplain B. Each router learns route entries directly from the route update and adds them to the routing table C. The router will send all the mis-routing status information from one neighbor to all other neighbors to ensure the synchronization of the database D. Routers in the flood domain may receive the same link state information repeatedly E. Routers throughout the flood domain have the same database of wrong-state states

Correct Answer: A,D,E

Question 10

CORRECT TEXT
When the BFD detection intervals on both ends are 30ms and 40ms, are the following options described correctly? An

A. BFD sessions cannot be established B. BFD sessions can be established, each occurring at its own interval C. BFD session can be established, which takes 40ms after negotiation D. BFD session can be established, which takes 30ms after negotiation

Correct Answer: B

Question 11

The following statement about OSPF route filtering is incorrect.( Single choice questions).

A. Interface-based filtering of LSAs allows all LSAs in the inbound and outbound directions except grace LSAs B. Filtering for the three types of LSAs needs to be configured on the ABR across OSPF regions C. In the NSSA area, filtering for external route ingestion and advertisement can be configured on ASBR or ABR D. Based on the link state database, when calculating routes, the fiter-policy import command is used, which only affects the route addition in the route table, and has no effect on the OSPF link state database

Correct Answer: A

Question 12

A switch joins a running stacking system after powering up, a behavior known as heap overlay.

A. FALSE B. TRUE

Correct Answer: B
