Question 6
A device receives two BGP routes with the same prefix from two peers (one route from each of the two peers). The next hop of one of the routes is NH1, and that of the other route is NH2. Other attributes of the two routes are the same. NH1 recurses to two direct next hops (A and B), and NH2 also recurses to two direct next hops (C and D). If the maximum load-balancing 2 command is configured for BGP and the device supports a maximum of six load-balancing routes, how many load-balancing routes with the relevant prefix exist in the FIB?

Question 7
On the transport network shown in the figure, two-level RRs are deployed, and RTA has a directly connected network segment 10.1.1.0/30. Which of the following statements are incorrect about the BGP deployment solution?
To enable level-2 RRs to learn the route to network segment 10.1.1.0/30, the level-2 RRs must be configured as clients of level-1 RRs.
It is recommended that RRs of the same level be configured with the same cluster ID.
RRs of the same level must be configured as clients of each other.
RTA and RTB can establish IBGP peer relationships with two level-1 RRs. RTA and RTB do not need to establish an IBGP peer relationship.
Question 8
Which of the following statements is incorrect about BGP RRs?
Fully meshed IBGP connections need to be established between non-clients.
A maximum of three levels of RRs can be deployed.
The routes learned from EBGP peers are advertised to all clients and non-clients.
RRs in different clusters need to establish fully meshed IBGP connections to learn routes from each other.
Question 9
On the network shown in the figure, RTA belongs to AS 100 and establishes an EBGP peer relationship with RTB. RTB, RTC, RTD, RTE, and RTF belong to AS 200. RTB, RTD, and RTE also belong to sub-AS 65001, RTC also belongs to sub-AS 65002, and RTF also belongs to sub-AS 65003.1. RTA imports a route 1.1.1.1/32. What is the AS_Path of the route after RTF receives the route?2. RTC imports a route 3.3.3.3/32. What is the AS_Path of the route after RTA receives the route?3. RTC imports a route 3.3.3.3/32. What is the AS_Path of the route after RTE receives the route?
100; 200; empty
(65003) (65001) 200 100; 200; 200
(65001) 100; 200; (65002)
(65001) 200 100; (65002) (65001) 200; (65002)
Question 10
During path calculation, if there are several paths with the same metric, CSPF selects one of them based on tie-breaking policies. Which of the following is not an available tie-breaking policy?
Select the link with the highest proportion of the used bandwidth to the maximum reservable bandwidth.
Select the link with the smallest proportion of the used bandwidth to the maximum reservable bandwidth.
Select the link with the smallest proportion of a single link cost to the total link cost.
