NO.40 the configuration file of the device. Is the following statement D wrong?

Regardless of whether the device is configured with apricotBPDU Tunnel,neither will be correctMSTPmake an impact

Port connected to user terminal equipmentMSTPWhether it is disabled or configured as an edge port

Check port configuration to confirm enableMSTPWhether the port is enabled with the protocol packet sending command. Such as:bpdu enable

Check if the port is added to the correct oneWLAN

NO.41 During an attempt to log in to a NetEngine AR6120 through the console port, the network engineer finds that the password is incorrect and the login fails. If a Telnet account can be used to log in to the device and the account has the permission to change the console port password, the network engineer can log in to the device through Telnet to change the console port password.

TRUE

FALSE

NO.42 Regarding the difference between NSR and NSF, which one is correct?

NSF does not need neighbor routers to complete

NSR must rely on neighboring routers to complete

NSF must rely on neighbor routers to complete

Both NSR and NSF need neighbor routers to complete

NO.43 On a stable network that requires fast route convergence, you can change the value of the interval at which OSPF LSAs are updated to 0 so that topology or route changes can be immediately advertised on the network through LSAs, which speeds up route convergence.

TRUE

FALSE

NO.44 (Multiple Choice) Which LSAs in OSPFv3 can be flooded in an area?

Link-LSA

Inter-Area-Router-LSA

Inter-Area-Prefix-LSA

Intra-Area-Prefix-LSA

NO.45 On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?

If the link between R1 and SI is disconnected, Rl recalculates the optimal path to R3 and performs path switching instantly.

If the link between R2 and SI is disconnected, R1 recalculates the optimal path to R3 and performs path switching instantly.

If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3 because FRR is enabled on R1.

If the link between R1 and SI is disconnected and you check neighbor information on R1, the neighbor relationship between R1 and R2 will instantly display Down.

NO.46 As shown in the figure, the cost value of the link that all interfaces of the router enable DSPF is identified in the figure.

The Loopback D interface of R2 is advertised in area 1. Then the cost value of R1 to 10.2/32 is:

200

150

100

NO.47 In the MPLS network, there are different operation types for labels, among which the meaning of the “pop” action is:

Replace the top label with another value

existMPLSAdd the top label to the label stack

Replace the top label with another set of labels

existMPLSRemove the top label from the label stack

NO.48 To speed up the detection of link failures in an IS-IS network, you can associate IS-IS with BFD.

True

False

NO.49 Network administrator A wants to use A, CL to match only the four routing entries 1 and 3.57 in the figure. Ask the network administrator A at least how many A, CL rules do you need to configure?

NO.50 Please match the command with the function implemented.

display device-® Display version-® Display memory-usage-® Display cpu-usage-?

NO.51 Which of the following statements about the OSPFV3 packet format is correct?

HelloPackets no longer carry address informationInterface ID

OSPFversion number from2became3

removedAuthentication,AuthTypefield

HellotelegramoptionNo changes to the field

NO.52 As shown in the figure, MPLS LSP is set up in the network, and the goal is to establish an LDP session between SWA and SWB.

Configured correctly

No global enable requiredMPLS

No need to enable on the portMPLS

two devicesmpls Isr-idcannot be configured the same

NO.53 As shown in the figure, MPLS LSP is configured in the network, and the goal is to establish an LDP session between SWA and SWB, then which of the following statement is correct?

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

NO.54 In OSPF, the A, BR will convert all type 7 L SAs in the NSSA area to type 5 L SAs.

True

False

NO.55 The engineer used two routers to test the IPv6 service and simulated the interconnection between the headquarters and the branch by running BGP4+. As shown in the figure, an engineer captured the packet to check the Updte message sent by R1. Regarding the description of the message information, which of the following statements are correct? (Multiple choice)

The message describes only one BGP attribute, and the multi-protocol unreachable NLRI attribute

This message describes the currently revoked IPv6 route

The length of the top and top strength of the routing address described in the message is: 2001:db8:2345:1::1/128

The next hop address of the route described in this message is: 2001:db8:2345:1::1

NO.56 Which of the following is not included in OSPF Hello packets?
Options:

Network Mask

Process ID

Area ID

Router ID

Comprehensive and Detailed In-Depth Explanation:
* OSPF Hello packets are used to establish and maintain neighbor relationships between routers.
* Hello packets contain:# Router ID – Unique identifier for the OSPF router.# Area ID – Defines the OSPF area to which the router belongs.# Network Mask – Helps ensure routers are on the same subnet.
* Process ID is NOT included because the OSPF Process ID is a local parameter used only within the router itself and is not exchanged between routers.

NO.57 The OSPF protocol runs between CE and PE, when CE1 advertises the route of the site to CE2. Which of the following description is wrong?

When PE2 receives a BGP route from PE1 that carries a different Domain ID from the local one, it is correct for all LSAs, and PE2 will generate Type5 LSA or Type7 LSA

When PE2 receives the same Domain ID as the local BGP route sent by PE1, PE2 will generate Type3 LSA for Type1 LSA and Type2 LSA

When PE2 receives the same Domain ID as the local BGP route sent by PE1, for Type3 LSA, PE2 will generate Type5 LSA

The Domain ID configured by PE1 can be used as an extended community attribute of BGP and sent along with the route to PE2.
