On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2 and R5. In AS 65000, R1, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and R1, R4, R3, and R6 are clients. The IBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import- route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

A. The route 192.168.2.0/24 in the routing table of R4 has two different outbound interfaces.

B. The routing table of R4 contains two equal-cost default routes.

C. The routing table of R1 contains two equal-cost default routes.

D. The routing table of R1 contains the route 192.168.2.0/24.

In the figure, the company wants to ensure secure communication between the headquarters and branch, and isolate the R&D areas from non-R&D areas, without changing the current network deployment.
To meet this requirement, an administrator deploys BGP/MPLS IP VPN on the network.

Which of the following statements are true?

A. To implement communication between the headquarters and branch R&D areas, the RDs of VPN1 and VPN2 need to be set to the same value.

B. R&D areas and non-R&D areas have overlapping address spaces. Therefore, services in the two areas cannot be isolated.

C. To enable communication between the headquarters and branch R&D areas, both the ERT and IRT of VPN1 and VPN2 can be set to 100:100.

D. To isolate R&D areas from non-R&D areas at the headquarters, the RTs of VPN1 can all be set to 100:100 and the RTs of VPN3 can all be set to 200:200.

On the network shown in the figure, EBGP peer relationships are established between ASs through directly connected interfaces.
* OSPF is deployed in AS 65456 (with OSPF disabled on interconnected interfaces between ASs).
* R4 and R5 use Loopback0 to establish iBGP peer relationships with R6.
* The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router.
* R1, R2, and R3 import the external route 192.168.1.0/24 into BGP through the import-route command.

Which of the following statements are true?

A. For 192.168.1.0/24, R5 preferentially selects the route received from R2.

B. For 192.168.1.0/24, R4 preferentially selects the route received from R1.

C. For 192.168.1.0/24, if the default local-preference 150 command is configured on R3, R5 preferentially selects the route received from R3.

D. For 192.168.1.0/24, R6 preferentially selects the route received from R4.
