正解：B、C、D
質問 # 154
Which of the following options is incorrect:
- A. dynamicLSPDynamically established through the label publishing protocol, such asMP-BGP, RSVP-TE, LDP
- B. The principle to be followed when manually assigning labels is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node

質問 # 155
An engineer uses two routers to test IPv6 services, and simulates the interconnection between the headquarters and branches by running BGP4+. As shown in the figure, an engineer captures the packet to view the update message sent by R1.
Regarding the description of the message information, which of the following statements is correct?
- A. The message describes the currently revoked IPv6 route
- B. The route described in the message may be imported through import
- C. The next-hop address of the route described in this message is: 2001:db8::2345:1.:1
- D. The routing address prefix and its prefix length described in this message are: 2001:db8:2345:1::1/128/
正解：D
質問 # 156
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. PE1orPE2± of VPN Instance parameter configuration error
- B. PE1andPE2 between LSPTunnel not established
- C. PE1andPE2 not present BGP-VPN4 Enabling neighbors in unicast address family view
- D. PE1orPE2 with each other CEMisconfigu red routing protocol between
正解：C

ping -a Xc Ys z -vpn-instance M 10.5.16.2, the meaning of this command is:
- A. ShouldpingofICMPThe request packet size isZ(excludingIPandICMPhead)
- B. Shouldpingpackage sourceIFPaddress isX

正解：A、B、C、D
質問 # 158
If the display current-configuration can reach the IS-IS configuration, but there is no IS-IS configuration in the display saved-configuration, what does it mean?
- A. The running IS-IS configuration in the memory has been saved to the Flash
- B. The IS-IS configuration that the Flash is running is not saved to the memory
- C. No IS-IS command is entered
- D. The running IS-IS configuration of the memory is not saved to the Flash
正解：D
質問 # 159
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculation. As shown in the figure, a campus deploys both IPv4 and IPv6 and runs IS-IS to achieve network interconnection. R2 only supports IPv4. Which of the following statements is true about the topology calculation of this network?
- A. By default, in the shortest path tree formed by IPv6 network calculation, the path from R1 to R4 is: R1-R2-R4. Since R2 does not support IPv6, R2 will directly discard IPv6 packets after receiving them, causing traffic loss.
- B. By default, since R2 does not support IPv6, in the shortest path tree formed by IPv6 network calculation, the path from R1 to R4 is: R1-R3-R4
- C. By default, IPv4 and IPv6 networks will be calculated separately to form different shortest path trees
- D. If you want IPv4 and IPv6 network computation to form the same shortest path tree, you need to run the ipv6 enable topology ipv6 command to enable the IPv6 capability in the IS-IS process.
正解：B
質問 # 160
A park deployed IPv6 for business testing. There are 4 routers in the network, running OSPFV3 to realize the interconnection and intercommunication of IPv6 networks. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Regarding the description of the LSA, which of the following statements are correct? (Multiple choice)
- A. The IPv6 address prefix of the R2 interface GE0/0/0 is 2001:2343: 23: :/64
- B. The LSA shows that R2 does not support external routing, but participates in IPv6 routing calculations
- C. The router that generated the LSA is R2
- D. The link-local address of the R2 interface GE0/0/0 is FE80::2E0; FCFF:FECD:4F79
正解：A、C、D
質問 # 161
IEIF expands the functions of OSPF by taking advantage of the strong expansibility of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3. OSPFv3 is compatible with OSPFv2.
- A. False
- B. True
正解：A
質問 # 162
As shown in the figure, all routers run OSPF, because R3 is in the backbone area, so in the LSDB of R3 There are no three types of LSAO
- A. False
- B. True
正解：A
質問 # 163
When deploying BGPIMPLS IPVPN, when two VPNs have a common site, the common site must not use overlapping address space with other sites of the two VPNs.
- A. False
- B. True
正解：A
