• Question 351:

  On a PIM-SM multicast network, a network engineer finds that multicast clients cannot receive multicast data. Which of the following is not a possible cause of this problem?

  A. The unicast routes from multicast devices to the RP are unavailable.
  B. The downstream interfaces of multicast devices do not receive any (*, G) Join messages.
  C. Downstream interfaces of multicast devices are disabled from forwarding State-Refresh messages.
  D. The RP addresses of multicast devices are different.
  C. Downstream interfaces of multicast devices are disabled from forwarding State-Refresh messages.

• Question 352:

  The figure shows the logical network architecture of a migration project. The purpose of the migration is to add network device R4 between R2 and R3.

  OSPF runs between network devices.

  After the physical network is connected, a network engineer incorrectly imports the backup configuration of R3 to R4 during the migration. Given this, which of the following statements are true?

  

  Options:

  A. The OSPF neighbor relationship between R1 and R2 is not affected.
  B. An OSPF neighbor relationship can be established between R2 and R4.
  C. An OSPF neighbor relationship can be established between R3 and R4.
  D. An OSPF neighbor relationship can be established between R1 and R3.
  A. The OSPF neighbor relationship between R1 and R2 is not affected.
  C. An OSPF neighbor relationship can be established between R3 and R4.

• Question 353:

  The security protection actions that a secure MAC address can perform does not include which of the following?

  A. Protect
  B. Restrict
  C. Shutdown
  D. Remark
  D. Remark

• Question 354:

  As shown in the figure, MPLS/BGP IPVPN is deployed on the network. The MP-BGP neighbor relationship is established between PE1 and PE2 through the LoopbackD interface. After the configuration is complete, it is found that CE1 and CE2 cannot learn routes from each other. Run the command to check the error on PE2. The neighbor information is shown in the figure, what is the most likely cause of the problem?

  

  A. PE1orPE2fVPNInstance parameter configuration error
  B. PE1andPE2not presentBGP-VPN4Enabling neighbors in unicast address family view
  C. PE1andPE2betweenLSPTunnel not established
  D. PE1orPE2with each otherCEMisconfigured routing protocol between
  B. PE1andPE2not presentBGP-VPN4Enabling neighbors in unicast address family view

• Question 355:

  An OSPFv3 NSSA LSA is generated by an ASBR, describes routes to a destination outside the AS, and is advertised in an NSSA. Options:

  A. TRUE
  B. FALSE
  A. TRUE

• Question 356:

  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?

  A. R4
  B. R5
  C. R3
  D. R2
  C. R3
  D. R2

• Question 357:

  BGP allows you to use the filter-policy acl-number import command to filter received routes. The value of ad-number ranges from 2000 to 3999.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 358:

  In an MPLS domain, LSR can be divided into Ingress LSR, Transit LSR and Egress LSR according to the different processing methods of LSRs for data. For the same FEC. a certain LSR can be the Ingress LSR of the FEC or the Transit LSR of the FEC. LSRO

  A. True
  B. False
  B. False

• Question 359:

  In an operator's MPLSVPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route on PE1 and assigns a label of 1027 Released to PE2. The outgoing label of the MPLS LSR-ID of PE2 reaching PE1 is 1025o When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be a combination of the following 6 options?

  A. outer layer label:1025:inner label:1027
  B. outer layer label:1027:inner label:1027
  C. Layer Label:1027:inner label:1025
  D. Layer Label,1025:inner label:1025
  A. outer layer label:1025:inner label:1027

• Question 360:

  On the OSPFv3 network shown in the figure:

  Area 1 is a stub area, Area 2 is a common area, and Area 3 is an NSSA (Not-So- Stubby Area).

  The IPv6 address of Loopback0 on R6 is 2000::6/128. The router ID of each router is 10.0.X.X, where X is the router number. The stub no-summary command is configured in Area 1 on R2.

  Which of the following statements is true?

  

  A. The LSDB of R4 contains the Inter-Area-Prefix-LSA that is generated by R1 and describes 2000::6/128.
  B. The path for data packets from R4 to 2000::6 is R4 -> R1 -> R5 -> R3 -> R6.
  C. The routing table of R4 does not contain the route 2000::6/128.
  D. The path for data packets from R4 to 2000::6 is R4 -> R2 -> R6.
  C. The routing table of R4 does not contain the route 2000::6/128.
