Question 1

The router connects two EBGP neighbors through two parallel Serial cables, what do you do to achieve

bidirectional negative sharing between two EBGP neighbors connected by these two parallel Serial cables? (

Single choice questions).

Options :

A :

Without any method, BGP automatically implements load sharing of traffic across different autonomous

systems on the available links

B :

Use the Loopback interface to establish an EBGP neighbor relationship, configure EBGP Muti-hop,

configure the Loopback interface as the update source, and then use IGP to implement Equivalent path

load sharing between Loopback addresses

C :

Configure the EBGP neighbor relationship with the Loopback interface as the update source, and the

IGP in each AS needs to introduce two equivalent paths to the loopback address of the EBGP neighbor;

And you need to use the command "next-hop?local"

D : Use the command "ebgp-load-balance" at both ends

E :

To configure an EBGP neighbor relationship with the Loopback interface as the update source, the IGP

in each AS needs to introduce two equivalent paths to the EBGP neighbor loopback address ; And the

commands "ebgp maxhop" and "next-hop-local" are used

Answer: B

Question 2

The RSTP protocol provides a variety of protection functions, such as when the edge port is configured as a protection state, the edge port receives the BPDU packet processing method;

Options :

A : Directly discard the BPDU packet

B : Close the port

C : After parsing the BPDU message, the relevant information is obtained

D : Forward BPDU packets as required

Answer: B

Question 3

The Option field in OSPFv3 appears in all LSAs

Options :

A : True

B : False

Answer: B

Question 4

Regarding the FTP protocol, which of the descriptions below is correct?

Options :

A : In FTP Passive mode, the client completes the initialization of the TCP session for control and data

B : In FTP Active mode, the server tells the client which port it expects to send data on by commanding "PORT"

C : FTP always uses a TCP session to transmit control information and data information

D : FTP always uses TCP port 20 to establish a data session, and ICP port 21 to establish control will always use

E : FTP TCP port 21 to establish a data session, TCP port 20 to establish a control session

Answer: A

Question 5

A routing tool can define multiple entries. Which tool will automatically add a deni-any entry at the end of the

configuration?

Options :

A : Route policy

B : Community-tilter

C : IP-prefix

D : AS-path-filter
