A. The PIM router with a long interface mask is elected as the DR. B. A router with a small IP address is elected as a DR. C.

A PIM router with a low DR priority value is elected as the DR.

Correct Answer: C

You need to configure policy routing on the router to specify that specific traffic is forwarded through an interface. When using policy-based routing, which two types of most typical information can be used to forward traffic along a particular path?

A. Source IP address and Layer 2 source address B. Source IP address and specific protocols (such as FTP, HTTP, etc.) C. TTL and source IP address of the data packet D. Service type header and packet length

Correct Answer: B

Question 4

A. Private network IP routing FRR between the PE and CE B. Configure CE dual-homing networking on the access layer. C. VPN FRR D. VPN GR

Correct Answer: A,B,C,D

Question 5

In RSTP, which port can provide the backup path that has reached to the root node of the spanning tree? What state is the port?

A. Alternate port and Learning state B. Alternate port and Forwarding state C. Designate port and Listening state D. Root port and Listening state E. Alternate port and Discarding state

Correct Answer: E

Question 6

About the domain-authentication-mode md5 hello command in the ISIS process, which of the following is the correct explanation?

A. The routing domain authentication is used to enable SNPs and LSPs of Level-1 and Level-2 to carry authentication information during the delivery process. B. ISIS certification cannot be applied in IPv6 environment. C. The domain authentication mode of all routers in the same routing domain is MD5, the password is hello, and the ISIS SNP and LSP spread normally. D. This command is mainly used to enable ISIS Hello packets to carry authentication information during the delivery process.

Correct Answer: C

Question 7

As shown in the following figure, enterprises hope to achieve successful access VPN between headquarters and branches through MPLS.

Branch office VPN traffic must be forwarded through the headquarters for traffic monitoring.
Which of the following statement about this solution is wrong?

A. BGP can be used to exchange VPN routing information between the CE and the PE. B. You can establish an MP-IBGP peer relationship between the Spoke-PEs and exchange VPN routing information. C. When Hub-CE and Hub-PE use EBGP to transmit routing information, the Hub-PE must be able to accept routes that are repeated by the AS number to receive routes advertised by the Hu-CE. D. OSPF can be used to exchange routing information between the Hub-CE and the Hub-PE and between the Spoke-PE and the Spoke-CE.

Correct Answer: B

Question 8

Which of the following is the correct description of the Register message in PMSM? (Multiple choice)

A. Register message is sent to the RP by unicast instead of multicast. B. Register message is sent by the receiver router C. Register message enables the RP to learn multicast source information. D. Register message is sent by the source DR

Correct Answer: A,C,D

Question 9

In the command aggregate ipv4-address {mask | mask-length} [ as-set | attribute-policy route-policy-name1 | detail-suppressed | origin-policy route-policy-name2 | suppress-policy route-policy-name3], multiple parameters can be used to influence the summary route and its results. What is the correct description about this command?

A. If As-set is configured, AS_ATH of the summary route contains AS path information of all specific routes to prevent routing loops. B. If the Suppress policy is configured, the aggregated route is generated. The if-match clause of the route-policy is used to select the detailed route to be suppressed. The detailed route matching the route-policy is still advertised to other BGP neighbors. C. If the Origin-policy is configured, only the detailed routes matching the Route-policy can participate in the aggregation. D. If Attribute-policy is configured, you can change the attributes of the aggregated route.

Correct Answer: A,C,D

Question 10

Regarding the cross-domain VPN-OptionB scheme, which of the following description is wrong?

A. During the packet forwarding process, exchange the private network LSPs of the VPN on the two ASBRs. B. An IP-EBGP neighbor relationship needs to be established between the two ASBRs. C. The cross-domain VPN-Option B scheme is not limited by the number of interconnected links between ASBRs. D. Exchange the outer label of the VPNv4 route between the two ASBRs.

Correct Answer: D

Question 11

Which of the following technologies use tunneling technology to communicate between IPv6 addresses? (Multiple Choice)

A. NAT64 B. Dual Stack C. 6to4 D. ISATAP

Correct Answer: C,D

Question 12

In Huawei devices, when ISIS imports external routes and sets external route tags for routing information, ISIS's metric types do not need to be modified, keep the default.

A. False B. True

Correct Answer: A

Question 13

Which statements regarding IBGP or EBGP neighbors are true? (Multiple Choice)

A. IBGP neighbor peering can be established using the loopback interface address. B. EBGP neighbor peering must use the physical interface address to establish peering. C. EBGP peers must be directly connected; otherwise, the EBGP-multihop option must be configured. D. BGP updates from an EBGP peer are propagated to other IBGP and EBGP peers. E. BGP updates from an IBGP peer are propagated to other IBGP and EBGP peers. F. IBGP peers must be directly connected; otherwise, the IBGP-multihop option must be configured.

Correct Answer: A,C,D

Question 14

Which of the following options may affect the establishment of IBGP neighbors? (Multiple Choice)

A. IGP routing is unreachable B. The BGP protocol version is inconsistent C. Authentication is unsuccessful D. IBGP - Multi-hop not configured
