  D. Location of key risk points
  A. loss from risk

• Question 362:

  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
  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

• Question 363:

  As shown in the figure, on the R1 router, network administrator A sends the routing entry to R2 through the routing policy After modifying the MED value, you can control the path of traffic entering the AS100

  

  A. True
  B. False
  A. True

• Question 364:

  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. In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are RRs (Route Reflectors), and R1, R4, R3, and R6 are clients. The iBGP peer relationships are established using Loopback0 on each router, and the router ID is 10.0.0.X/32, 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?

  

  A. The routing table of R4 contains two equal-cost default routes.
  B. The route 192.168.1.0/24 in the routing table of R3 has two next hops.
  C. The routing table of R1 does not contain the route 192.168.2.0/24.
  D. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.
  D. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.

• Question 365:

  Large and midsize enterprise networks can be divided into the access layer, aggregation layer, and core layer. Network engineers need to work out a migration solution for the operations to be performed at any layer, as long as the operations affect services on the live network.

  Options:

  A. TRUE
  B. FALSE
  A. TRUE

• Question 366:

  ping -a Xc Ys z -vpn-instance M 10.5.16.2, the meaning of this command is:

  A. ShouldpingsendYindivualICMPask
  B. ShouldpingofICMPThe request packet size isZ(excludingIPandICMPhead)
  C. Shouldpingpackage sourceIFPaddress isX
  D. Shouldpingpackage belongs toVPNexampleM
  A. ShouldpingsendYindivualICMPask
  B. ShouldpingofICMPThe request packet size isZ(excludingIPandICMPhead)
  C. Shouldpingpackage sourceIFPaddress isX
  D. Shouldpingpackage belongs toVPNexampleM

• Question 367:

  To speed up the detection of link failures in an IS-IS network, you can associate IS-IS with BFD.

  A. True
  B. False
  A. True

• Question 368:

  OSPF requires that routers in the same area have the same link state database (LSDB). As the number of routes on the network increases, some routers cannot carry so much routing information due to limited system resources. This state is called database overflow. If the Isdb-overflow-limit number 7 command is run on all routers on an OSPF network, which of the following conditions are likely to cause routers to enter the overflow state?

  A. The number of Type 4 LSAs exceeds 7.
  B. The number of Type 5 LSAs exceeds 7.
  C. The number of Type 7 LSAs exceeds 7.
  D. The number of Type 3 LSAs exceeds 7.
  B. The number of Type 5 LSAs exceeds 7.

• Question 369:

  A network engineer entered the following information when troubleshooting OSPF faults. Based on this, you can judge what causes the adjacency relationship to fail to be established normally?

  

  A. Authentication passwords do not match
  B. Inconsistent area type
  C. Hell. Inconsistent message sending interval
  D. interfaceIPInconsistent address masks
  D. interfaceIPInconsistent address masks

• Question 370:

  On the OSPF network shown in the figure:

  Area 1 is a common area.

  Area 2 is a totally NSSA (Not-So-Stubby Area).

  Area 3 is an NSSA.

  R5 imports the external route 10.0.5.5/32 into OSPF. Which of the following routers have the route 10.0.5.5/32 in their routing tables?

  

  A. R4
  B. R2
  C. R6
  D. R3
  B. R2
  C. R6
  D. R3
