• A.  Efficient TI-LFA FRR protection is provided for fast path fault recovery.
• B.  Only the controller can compute paths based on explicit paths.
• C.  SR-MPLS supports smooth network evolution by extending existing protocols, such as IGPs.
• D.  Such networks can quickly interact with upper-layer applications through the source routing technology.

Which of the following statements is incorrect about MP-BGP?

• A.  When PEs and CEs exchange routes through BGP, you need to create a BGP process for each VPN instance in the CE.
• B.  The packet types and VPNv4 route advertisement policies of MP-BGP are the same as those of BGP-4.
• C.  MP-BGP needs to allocate private network labels for VPNv4 routes.
• D.  MP-BGP uses the MP_REACH_NLRI and MP_UNREACH_NLRI attributes to advertise VPNv4 routes.

A network administrator runs the display telemetry subscription command on a device to check telemetry subscription information. The command output is as follows. Which of the following statements is incorrect?
[~CE] display telemetry subscription
Sub name : Sub1
Sensor group:
Sensor-name Sample-interval(ms) State
Sensor1 1000 RESOLVED
Destination group:
Dest-name Dest-IP Dest-port State Vpn-name Protocol
Dest1 192.168.56.1 20030 RESOLVED - GRPC
Sub state : PASSIVE
Total subscription number is : 1

On the campus network shown, IPv6 is deployed for service tests. Four routers are deployed on the network, and these routers use OSPFv3 for network connectivity. Which of the following statements about LSAs generated by the OSPFv3 network is incorrect?

• A.  The LSDB of R1 contains Network-LSAs generated by R3, indicating that R3 may be the DR on the local link.
• B.  R2 functions as an area border router (ABR), generates Inter-Area-Prefix-LSAs that describe the IPv6 address prefix of area 1, and advertises these Inter-Area-Prefix-LSAs to R1 and R3.
• C.  R1 receives two Link-LSAs generated by R2. The two Link-LSAs describe information about the two links connected to R2.
• D.  R1 generates Router-LSAs describing interface information and receives Router-LSAs generated by R2 and R3.
