Q121. Display interface GE0/0/0 once, and find that the Total Eror count (the total number of error packets on the physical layer of the interface) is not 0. At this point, it can be concluded that the current fault has not disappeared.

Q122. 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

Q123. Please match 0SPFv3LSA with its transmission range.

AS-external-LSA Autonomous system-wide intra-regional propagation
Network-1SA intra-regional spread

Q124. As shown in the figure, all interfaces of the router enable OSPF. The ip address identified in the figure is the IP address of the device’s Loopback 0 port. R1, R2, R3EJLoopbacD are advertised in area 1, and Loopbacfk D of R4 is advertised in area D, the Loopback D of R5 is advertised in area 2. Which of the following addresses can ping each other?

Q125. By executing the () command, users on different ports of the same VLAN can be completely isolated at Layer 2 and Layer 3 and cannot communicate. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)

Q126. As shown in the figure:

Q127. 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?

Q128. When deploying MPLS/BGP IP VPN, which of the following descriptions is wrong about using BGP to exchange routing information between PEs and CEs?

Q129. According to this picture, what can we judge? (Multiple choice)

Q130. When troubleshooting a network, if you need to confirm the business traffic path, which of the following may need to be done ()

Q131. The RR rules for advertising routes violate the IBGP split horizon rules, which may cause loops in the AS. Which routing attributes does RR use to prevent loops?

Q132. The network administrator A wants to use ACL to match only the four routing entries 1, 3.5, and 7 in the figure. How many ACL rules does the network administrator A need to configure at least?

Q133. . OSPFv2 is an IGP running on an IIPv4 network. OSPFV3 is an IGP running on an IPv6 network. Compared with OSPFv2, OSFv3 has similar LSA, but the function is slightly different. The following is the description of the LSA function of OSPFv3. Please drag the LSA to the correct LSA function column.

Q134. As shown in the figure, configure a backhaul summary route 10.0.0.0/24 on the border route RT1. next hop to RT2. At the same time, the default route to the external network is configured. At this point, a routing black hole will appear. The following is about routing Is the black hole statement correct? (multiple choice)

Q135. Which of the following reasons may cause the hosts in the same VLAN of the LAN to fail to communicate with each other?

Q136. As shown in the figure, R1, R2, R3, and R4 are in the same MPLS domain, and LDP is used to allocate MPLS labels between devices. R4 is the FEC Egress LSR of 4.4.4.0/24. If you want to realize that when R1 accesses 4.4.4.0/24, R4 does not need to query the label table but can understand the forwarding priority of the data, then R3’s outgoing label for the FEC should be (). (Please fill in the Arabic numerals directly, without symbols)
