Question 42

RTA is a leaf router that directly connects to host A through interface GigabitEthernet 1/0/0. The interface is configured as follows:
interface GigabitEthernet1/0/0
undo shutdown
ip address 192.168.4.2 255.255.255.0
pim sm
igmp enable
igmp version 3igmp ssm-mapping enable
igmp static-group 232.1.1.1
Configurations in the IGMP view are as follows:
igmp
ssm-mapping 232.1.1.0 255.255.255.0 10.10.1.1
ssm-mapping 232.1.2.0 255.255.255.0 10.10.1.1
Host A sends an IGMPv2 Report message to group 232.1.2.2. Which entry can be displayed by the display igmp ssm-mapping group command?

A.(10.10.1.1, 232.1.1.1) and (10.10.1.1, 232.1.2.2)

B.(10.10.1.1, 232.1.1.1)

C.No entry

D.(10.10.1.1, 232.1.2.2)

Question 43

When the RSVP LSP FRR protection is enables, which of the following statements about the original RSVP LSP are true?

A.The RESV message is sent by the MP to an upstream node through a bypass LSP after modified.

B.The point of local repair (PLR) and the merge point (MP) can perceive the application of FRR but other nodes on the original RSVP LSP

C.The PATH message is sent by the PLR to the MP through a bypass LSP after modified.

D.The MP sends the ResvTear message to the upstream node of the original RSVP LSP.

Question 44

Which of the following statements about the working principle f LDAP FRR are true?

A.After LDP FRR enable, a backup can degenerated for a primary LSP to prevent serious packet loss during fats flapping of the primary LSP.

B.Multiple LSPs can be up on the ingress node, that is entries about multiple backup LSPs are generated in the forwarding table according to the priority of the FRR, implementing multi-layer protection.

C.After LDP FRR is enabled, a backup LSP is generated both the primary and backup LSPs are stored in the forwarding table.

D.LDP TFRR can be deployed on the ingress node and the intermediate node. The primary and backup LSPas are recorded in the ILM table on the intermediate node and on the FIB table on the ingress node.

Question 45

Which statement about the OSPF VPN is true? (B)

A.A VPN instance can include multiple OSPF processes. An OSPF process can be bound to multiple VPN instances.

B.An OSPF process can be configured with one or multiple primary domain IDs.

C.When a PE is an OSPF ABR, the PE is connected to a CE only in a non-backbone OSPF area.

D.OSPF ASs are differentiated by domain ID. Therefore, devices within one AS must be configured with the same domain ID.
