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

When the ABR is a Type 5/7 LSA Switch router in the NSSA zone, then the ABR can be used against the

Type 7 LSA The converted type 5 LSA is aggregated.

Options :

A : True

B : False

Answer: A

Question 3

When deploying BGP/MPLS IPVPN, OSPF's VPN route tag is not present

The extended properties of MP-BGP are passed only locally, only locally, and only meaningful on routers that

receive MP-BGP routes and generate OSPF LSAs.

Options :

A : TRUE

B : FALSE

Answer: A

Question 4

The address resolution feature for NDP in the following description is incorrect?

Options :

A : When sending a neighbor request packet, the source address—is set as the link-local address

B : of the local interface Two types of ICMPv6 messages,

C : are used in the address resolution process, neighbor request and neighbor advertisement Address resolution implements the ability to resolve from IPv6 addresses to link-layer addresses

D : When sending a neighbor request packet, the destination address must be the multicast address of the neighbor-s requested node

Answer: A

Question 5

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
