NO.34 A network engineer outputs the following information when troubleshooting OSPF. Based on this, determine which reason causes the adjacency relationship to fail to be established normally?

NO.35 MPLS is called multi-protocol label switching. Which description is correct about the label in MPLS? (Multiple choice)

NO.36 Which of the following are not included in the security protection actions that a secure MAC address can perform?

NO.37 As shown in the figure, network administrator A on the R1 router, after modifying the MED value of the routing entry sent to R2 through the routing policy, can control the path of traffic entering AS100.

NO.38 The routing attributes of the three routing entries are shown in the figure. Assuming that the next hop of the three routing entries are all reachable, when the three routing entries arrive at the BP router in sequence, by default, BGP will finally select one route entry?

NO.39 The routing policy tools that can be used by BGP mainly include Filterpolicy and oRoute-policy.
Fiterpolicy can only filter routes, Rote – policy can only modify routes

NO.40 The link status information between different S.4S processes of the routers around the Taiwan and Taiwan is considered to be sound insulation.

NO.41 Which of the following reasons may cause the hosts in the same–VLAN LAN to fail to communicate with each other

NO.42 Which statements are wrong about OSPF Router LSA and Network LSA? (Multiple choice)

NO.43 Ethernet is a broadcast-enabled network, and once there are loops in the network, this simple factory broadcast mechanism can have disastrous consequences. Which of the following phenomena may be caused by loops?

NO.44 As shown in the figure, all interfaces of the router enable OSPF, among which R4 and R5 can establish OSPF virtual connections.

NO.45 Which of the following description of the configuration on this switch is correct? (Multiple choice)

NO.46 Which of the following sequences can be matched by the regular expression 100.S

NO.47 The rollback operation of project cutover can be temporarily determined according to the situation during cutover, and no advance plan is required.

NO.48 The Router ID of OSPFv3 needs to be configured in dotted decimal notation with a length of 128bits.

NO.49 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)

NO.51 According to this picture, what can we judge? (Multiple choice)

NO.52 Engineer Guan used two routers to test IPv6 services. By running the BGP4+ module to communicate with the branch, as shown in Juxin, an engineer captured packets to view the Updte packets sent by R1. Which of the following statements is true about the description of the message information?

NO.53 What is the meaning of display current-configuration I include vlan command?

NO.54 [According to this picture, Peimen can judge?
cR3>display ipv6 routing-table protocol isis

NO.55 In the multi-level RR scenario, a large number of secondary RRs will be connected to the primary RR, which may lead to BGP of the primary RR. The routing table overflows, what method can be used to reduce the risk of overflowing the routing table of the advanced RR BGP?
