質問 3：
OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is____. (Note: Please fill in the IP address without mask)

正解：
(10.1.23.2)

質問 4：
As shown in the figure, in a medium-sized network, BGP generally deploys dual RRs to improve R reliability. When deploying dual RRs, the Cluster IDs of the two RRs are generally set to be the same. The reason for this is

B. Prevent RR from receiving too many routes and causing insufficient memory
C. Prevent the client from receiving too many routes and causing it to run out of memory
D. prevent suboptimal
正解：B

質問 5：
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
Label, a description of the two-layer label in the following options. What is wrong is:
A. MPLS VPNThe outer label is made byLDPprotocol or statically assigneD. the inner label is assigned by the correct end MP-BGPassigned by neighbors
B. By default, the outer label is popped before the packet is forwarded to the last hop device
C. M PLS VPNThe outer layer is labeled as a private network label, and the inner layer label is called a public network label.
D. Layer labels are used inPEThe device sends the packet correctly to the correspondingVPNmiddle
