Question 1

The HTTP protocol is based on TCP, so http Flood attacks can be defended against HTTP Flood attacks using

the TCP Flood attack prevention method.

Options :

A : True

B : False

Answer: B

Question 2

Regarding the BGP alliance, the following description is wrong? Radio

Options :

A : The consortium divides an AS into sub-AS, and the alliance external AS still considers the consortium to be an AS

B : Subsystems within a consortium can use private AS numbers. Huawei NE/AR routers, a consortium can be configured with up to 32 subsystems.

C : Consortium can easily detect the routing loop within the AS because EBGP is running between the subAS

D : The subas number of the federation, which by default is advertised to the BGP peer outside the federation

Answer: D

Question 3

Which of the following is incorrect about HTTPS?( Multiple Choice)

Options :

A : HTTPS secures access to data by using SSLVPN.

B : If the HTTPS traffic contains a virus, the router cannot detect the virus directly using IPS technology

C : When using HTTPS to access a website, the website cannot be accessed if the user-s browser does not recognize the website-s digital certificate.

D : HTTPS protocol uses TCP port 443 by default

Answer: C

Question 4

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

Answer: A,B,C,D

Question 5

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
