The configuration is correct

No need to enable MPLS globally

No need to enable MPLS on the port

Two devices mpls lsr-id cannot be configured as the same

6. 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?

9. Regarding BGP/MPLS IPVPN routing interaction, which of the following descriptions is wrong?

The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routing

After the egress PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route

The exchange between PE and CE is IPv4 routing information

The ingress PE changes the IPv4 route received from CE to VPNv4 route, and saves it according to different VPN instances

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

The VPN instance parameters on PE1 or PE2 are incorrectly configured

PE1 and PE2 are not enabled with neighbors in the BGP-VPN4 unicast address family view

dir sdl:

dir sd0:

display patch-information

dir flash:

16. As shown in the figure, a certain park has deployed IPv6 for service testing, and there are 4 routers in the network. Run OSPFv3 to realize network interconnection.

Regarding the LSA generated by the OSPFv3 network, which of the following statements is wrong?

R1 itself will generate Router-LSA to describe device interface information, and will receive Router-LSA generated by R2 and R3 at the same time

There is a Network LSA generated by R3 in the LSDB of R1, indicating that R3 may be the DR of this link

R1 will receive the two Link-LSAs generated by R2, describing the two links information connected to R2 respectively

As an ABR, R2 will generate Inter-Area-Prefix-LSA describing the IPv6 address prefix of Area 1, and advertise it to R1 and R3

17. As shown in the figure, all interfaces of the router enable OSPF, among which R4 and R5 can establish OSPF virtual connections.

TRUE

FALSE

18. Which of the following is not part of the preliminary preparations for the cutover plan?

On-site defense

Cutover target

19. 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.

TRUE

FALSE

20. R1 executes the operation ping -a 10.1.1.1 10.5.16.2, what does this command mean?

The source IP address of the ping packet is any directly connected port address of R1

The source IFP address of the ping packet is the outgoing interface address of the optimal IP route that R1 points to 10.5.16.2, and is not 10.1.1.1

The source IP address of the ping packet is 10.1.1.1

The destination IP address of the ping packet is 10.1.1.1 and 10.5.16.2

Cable connectivity test

22. An engineer used two routers to test IPv6 services, and simulated the interconnection between headquarters and branches by running BGP4+.

The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between two devices, which of the following statements is wrong?

When routing, the Next_Hop attribute must be an IPv6 global unicast address

BGP4+ transmits routing information between peers through Update messages

If the Update message carries the MP_REACH_NLRI attribute, it means that the advertised route is reachable

When routing, it will carry AS_Path and other recognized mandatory attributes

23. An enterprise purchased the leased lines of two operators. In order to optimize the route, the enterprise used the 6GP protocol to learn routing entries of the two operators. However, the company found that after such a configuration, the traffic of the export routing increased greatly. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the company's export router.

Therefore, the company intends to use routing strategies to prevent the traffic between different operators from passing each other. Is the configuration in the figure correct?

TRUE

FALSE

24. Which of the following descriptions is wrong?

The LSP established by statically assigning labels can also be dynamically adjusted according to network topology changes without the intervention of the administrator

The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node

LSP is divided into static LSP and dynamic LS

The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol

Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE, LDP

25. What is the flooding scope in OSPFv3 for the LSA in the entire autonomous system?

Link-LSA

As-external-LSA

Inter-Area-Prefix-LSA

Intra-Area-Prefix-LSA

26. When there are multiple redundant links in the IS-S network, multiple equal-cost routes may appear.

Regarding equal-cost routes in an IS-IS network, which of the following descriptions is wrong?

When the number of equal-cost routes in the networking is greater than the number configured through commands, and the priorities of these routes are the same, the route with the higher System ID of the next hop device is preferred for load sharing

If negative arbitration sharing is configured, the traffic will be evenly distributed to each link

After the equal-cost routing priority is configured, when the IS-IS device forwards the traffic that reaches the destination network segment, it will not adopt the load sharing method, but will forward the traffic to the next-hop with the highest priority.

For each route in the equal-cost route, the priority can be specified, and the route with the higher priority will be preferred. The rest are used as backup routes

27. Which of the following regarding the configuration description is wrong?

If the DHCP request message received by the GigabitEthemnet0/0/1 interface does not contain the SutOption information of Option82, the device will generate Option82 and insert it into the message

Enabling the DHCP Snooping configuration can be used to prevent DHCP Server counterfeiters from attacking

Configure GigabitEthernet0/0/1 as a trusted interface

Enabling the DHCP Snooping configuration can be used to prevent ARP spoofing attacks

28. According to this figure, it can be known that in VLAN300, 0 MAC drift occurred by 00e0-fc3d-3bdb from 17:22:38 to 17:22.44 on 2020-06-04.
