  A. Level 1 and level 2 IS-IS BFD sessions are set up among RTA, RTC, and RTD.
  B. Level 2 IS-IS BFD sessions are set up among RTA, RTC, and RTD, and a level 1 IS-IS BFD session is set up between RTC and RTD.
  C. Level 2 IS-IS BFD sessions are set up between RTD and RTA as well as between RTD and RTC, and a level 1 IS-IS BFD session is set up between RTC and RTD.
  D. Level 1 and level 2 IS-IS BFD sessions are set up only between RTC and RTD
  C. Level 2 IS-IS BFD sessions are set up between RTD and RTA as well as between RTD and RTC, and a level 1 IS-IS BFD session is set up between RTC and RTD.

• Question 3:

  # interface Ethernet6/1/1 ip address 40.1.1.4 255.255.255.0 igmp prompt-leaveigmp enable pim sm # IGMP interface group report information of VPN-Instance: public net Ethernet6/1/1(40.1.1.4): Total 1 IGMP Group reported Group: 224.1.2.3 Uptime: 00:00:32 Expires: 00:04:38 Last reporter: 30.1.1.30 Last-member-query-counter: 0 Last-member-query-timer-expiry: off Version1-host-present-timer-expiry: off The preceding information shows the configurations of Ethernet 6/1/1 and entries created based on received IGMPv2 Report messages. Which action does Ethernet 6/1/1 perform after receiving Leave messages for group 224.1.2.3?

• Question 4:

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

  A. After LDP FRR is enabled, a backup LSP is generated both the primary and backup LSPs are stored in the forwarding table.
  B. 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.
  C. After LDP FRR enable, a backup can degenerated for a primary LSP to prevent serious packet loss during fats flapping of the primary LSP.
  D. 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 enable, a backup can degenerated for a primary LSP to prevent serious packet loss during fats flapping of the primary LSP.
