Question 1

The Origin attribute of the BGP route that is imported by using the network command is IGP.

Accepted Answer

The BGP Origin attribute for routes injected using the network command is set to IGP, indicating the route originated from within the local autonomous system.

Question 2

In the BGP routing table, if there are two BGP routes with the same destination address but different next hops, which statement about the two BGP routes is true?

Accepted Answer

Only the optimal route selected from the two BGP routes is advertised to other BGP peers. BGP selects the best path based on its path selection criteria and only advertises that path to its peers.

Question 3

In OSPF protocol, which of the following elements are used to describe one link? (Choose three.)

Accepted Answer

The answer of In OSPF protocol, which of the following...

Question 4

If the hold timers in the Open messages sent from BGP Peer A and Peer B are 180s and 90s respectively, what is the interval at which Keepalive messages are sent after Peer A and Peer B have established a BGP peer relationship?

Accepted Answer

The Keepalive message interval is set to one-third of the negotiated hold timer. The negotiated hold timer is the lower of the two hold timers, which is 90s. Therefore, the Keepalive interval is 90s / 3 = 30s.

Question 5

In OSPF protocol, which of the following statements are incorrect regarding Link ID of Router LSA? (Choose two.)

Accepted Answer

The answer of In OSPF protocol, which of the following...

Question 6

Which of the following statements is false?

Accepted Answer

The metric of an external route is not the sum of the AS external metric and the AS internal metric; this description is incorrect for both Type-1 and Type-2 external routes in OSPF.

Question 7

Which attributes are well-known community attributes? (Choose three.)

Accepted Answer

NO_EXPORT, NO_ADVERTISE, and NO_EXPORT_SUBCONFED are well-known community attributes.

Question 8

What is the Origin attribute of the BGP route that is imported by using the import-route command?

Accepted Answer

The Origin attribute of a BGP route imported using the import-route command is set to "Incomplete" because the route's origin is not known to be from an IGP or EGP.

Question 9

In OSPF area, RTA and RTB interconnect through FE interface. which of the following commands can be used to configure the link cost between RTA and RTB as 10? (Choose two.)

Accepted Answer

The answer of In OSPF area, RTA and RTB interconnect...

Question 10

Which statement is true if MD5 authentication is configured during the configuration of a BGP peer?

Accepted Answer

A pair of BGP peers must use the same MD5 password to authenticate each other, ensuring secure communication between them.

Question 11

Which of the BGP attributes are Well-known mandatory attributes? (Choose three.)

Accepted Answer

ORIGIN, AS_PATH, and NEXT_HOP are Well-known mandatory attributes in BGP.

Question 12

Which TCP port is used by BGP?

Accepted Answer

BGP (Border Gateway Protocol) uses TCP port 179 for establishing connections between routers to exchange routing information.

Question 13

What is private AS number?

Accepted Answer

Private AS numbers range from 64512 to 65535, which are reserved for private use in BGP routing.

Question 14

A failure in establishing a BGP peer relationship can be addressed by checking the TCP connectivity and BGP peer configurations.

Accepted Answer

Checking TCP connectivity ensures that the underlying network connection is functioning, and verifying BGP peer configurations ensures that the settings for establishing the BGP session are correct.

Question 15

Which of the following conditions must be met for importing routes to BGP by using the network command? (Choose two.)

Accepted Answer

The network command in BGP requires that the routes are present and optimal in the IP routing table (A) and that they match the specified mask length (C) to be advertised by BGP.

Question 16

The router ID configured in the system view takes precedence over the router ID configured in the BGP view.

Accepted Answer

The answer of The router ID configured in the system...

Question 17

In which state have BGP peers not established any connection and not initiated a connection request?

Accepted Answer

In the Idle state, BGP peers have not established any connection and have not initiated a connection request.

Question 18

Which of the BGP attributes is Optional transitive attribute?

Accepted Answer

The answer of Which of the BGP attributes is Optional...

Question 19

Which of the following statements belong to BGP COMMUNITY attribute? (Choose three.)

Accepted Answer

The answer of Which of the following statements belong to...

Question 20

BGP is an inter-AS routing protocol. Which statements about BGP are true? (Choose three.)

Accepted Answer

BGP uses TCP for reliable transmission, supports incremental updates to minimize bandwidth usage, and allows for complex routing policies to be implemented.
