NO.57 To protect a device against the attacks of forged BGP messages, you can configure GTSM to check whether the TTL value in the IP message header is within the specified range. If the peer x.x.x.x valid-ttl-hops 100 command is configured on a device, the valid TTL value range of the detected message is [155, 255].

NO.58 On the IS-IS IPv6 network shown in the figure:
* Multi-topology is enabled on all routers.
* The IPv6 address of Loopback0 on R4 is 2000::4/128.
* The command ipv6 summary 2000::/64 level-2 is configured in the IS-IS processes of R2 and R1.
* The command ipv6 import-route isis level-2 into level-1 is configured in the IS-IS processes of R1, R2, and R3.

Which of the following routers have the route 2000::/64 in their routing tables?

NO.59 As shown in the figure, the network has a loop because STP is not enabled. Which of the following phenomena may be bowed?

NO.60 As shown in the figure, OSPF is enabled on all interfaces of the router. Which of the following statements is correct?

NO.61 There is the concept of forwarding equivalence class FEC in MPLS, which of the following description is wrong? (Multiple choice)

NO.62 Which of the following options is incorrect:

NO.63 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?

NO.64 Which of the following will not cause the VRRP backup group to oscillate?

NO.65 If the display current-configuration can reach the IS-IS configuration, but there is no IS-IS configuration in the display saved-configuration, what does it mean?

NO.66 esigth uses different colors to distinguish different alarm levels, red represents emergency, orange represents important, and yellow represents The table is secondary, and blue represents the prompt. Which of the following statements about different alarm levels is correct: (multiple choice)

NO.67 The figure shows the Router-LSA generated by a router. Which of the following statements are true based on the LSA?

NO.68 In the network shown in the figure below, to implement a remote LDP session between SWA and SWC. the following The law is correct

NO.69 As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to implement network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to implement network interoperability. Now the engineer wants to implement R1 to access the loopback interface address of R4. Which of the following operations can meet this requirement?

NO.70 On the IS-IS network shown in the figure, R1 imports a default route using the default-route-advertise always level-1 command. Which of the following routers have the default route in their routing tables?

NO.71 After configuring the VLAN-based MAC address drift detection function, if the MAC address drifts, you can configure the actions of the interface according to your needs.
Which of the following is not a configurable action?

NO.72 Regarding the site in the BGPIMPLS IP VPN network architecture. Which of the following descriptions is correct?

NO.73 As shown in the figure, Client1 and Client2 act as clients of RR1 and RR2 at the same time, and RR1 and RR2 are in the same In a Cluster, R introduces 10 routes. It is assumed that the configuration of B, CP is correct. Neighbor relations have been established Now, how many routing entries exist in the BGP routing table of Client2?

NO.74 (Drag and drop) Network administrator A needs to permit or deny some specific routes, but administrator A is not proficient in configuration. Please help administrator A to sort the configuration reasonably so that the device can permit or deny specific routes according to the requirements in the figure.

NO.75 On the network shown in the figure, the DHCP server function is enabled on GEO/0/0 of R2, and the address pool is an interface address pool. When GEO/0/0 and GEO/0/1 of R1 function as DHCP clients, only one interface can obtain an IP address by default.
