NO.23 According to this figure, what can we judge? (Multiple choice)

NO.24 As shown in the figure, OSPF is enabled on all interfaces of the router, and the cost value of the link is marked in the figure. The Loopback0 interface of R2 is advertised in area 1, then the Cost value of R1 reaching 10.0.2.2/32 is:

NO.25 After a fault occurs, it is necessary to collect and backup various types of fault information in time as a reference for handling faults.

NO.26 To speed up the detection of link failures in IS-IS networks, you can associate IS-IS with BFD.

NO.27 In OSPF, ABR converts all Type 7 LSAs in the NSSA area to Type 5 LSAs.

NO.28 Assume that for the packets marked as AF21, the WRED discard policy is set to set the lower limit to 35, the upper limit to 40, and the discard probability is 50%. Then when the packet of AF21 arrives, which description is wrong about the processing result of the packet by WRED? (Multiple choice)

NO.29 As shown in the figure, Client1, Client2, and client3 act as clients of RR1 at the same time, and R1 introduces 10 routes.

Assuming that the BGP configuration is correct and all neighbor relationships have been established, how many routing entries exist in the BGP routing table of Client3?

NO.30 According to this picture, what can we judge? (Multiple choice)

NO.31 Different virtual machines can use the VTEP tunnel established by vswitchi to communicate with VXLAN. Then the communication process of VXLAN is: 1 The source VTEP encapsulates the ARP broadcast sent by the source VM into a multicast packet and sends it to the L3 network. 2 After receiving the multicast packet, the destination VTEP learns the mapping relationship between the source VM and VTEP, and forwards the multicast packet to the local VM. 3 Local unicast response. 4 The destination VTEP encapsulates the Vxlan tunnel, establishes a mapping table and encapsulates it, and then unicasts it to the source VTEP. 5 The source VTEP receives the response and establishes the mapping relationship between the target VM and the target VEP, removes the tunnel and forwards it to the source VM. 6 The source VM and the target VM communicate unicast packets through the tunnel.

NO.32 Configure IS-IS IPv6 enable on the interface. What is the meaning of this command?

NO.33 Configure ipv6 preference in IS-IS protocol view. The function of this command is to configure the priority of IPv6 routes generated by IS-IS protocol.

NO.34 According to this figure, what can we judge?

NO.35 Through the VLAN aggregation technology, one Sub-VLAN can correspond to multiple broadcast domains, which improves the flexibility of addressing.

NO.36 What information can be used for complex traffic classification in packets? (Multiple choice)

NO.37 Between different IS-IS processes of the same router, the link state information is isolated by default.

NO.38 The security protection actions that can be performed by a secure MAC address do not include which of the following?

NO.39 Which of the following statements about IS-IS (IPv4 6) is correct? (Multiple choice)

NO.40 Which of the following description of TTL in MPLS Header is correct?

NO.41 When MPLS is deployed in the network and the network layer protocol is IP, the route corresponding to the FEC must exist in the IP routing table of the LSR, otherwise the label forwarding entry of the FEC will not take effect.

NO.42 Part of the configuration of R1 is as follows. Which statement about OSPF on R1 is correct?

NO.43 Which statement is true about ASPF and Server-map? (Multiple choice)
