NEW QUESTION # 151
Refer to the exhibit:

NEW QUESTION # 152
Refer to the exhibit:
A network engineer is implementing an OSPF configuration Based on the output, which statement is true?
- A. OSPFv3 cannot be configured for IPv4; OSPFv3 works only for IPv6.
- B. In the ospfv3 1 area 1 ipv4 command, area 0 must be configured instead of area 1.
- C. OSPFv3 does not run for IPv4 on FastEthemet0/0 until IPv6 routing is enabled on the router and IPv6 is enabled on interface Fastfc.thernet0/0
- D. IPv6 routing not enabled" is just an informational message and OSPFv3 runs for IPv4 on interface FastEthernet0/0 anyway
Answer: D
Explanation:
OSPFv3 is designed to support both IPv4 and IPv6. The message "IPv6 routing not enabled" indicates that IPv6 has not been configured on the router, but this does not prevent OSPFv3 from running for IPv4. The OSPFv3 configuration for IPv4 will still function on the interface FastEthernet0/0 as intended.

NEW QUESTION # 157
What are two factors to consider when implementing NSR High Availability on an MPLS PE router? (Choose two.)
- A. It requires routing protocol extensions
- B. It cannot sync state information across redundant RPs
- C. It requires all PE-CE sessions to support NSR
- D. It operates normally without NSR support on the PE peers.
- E. It consumes more memory and CPU resources than NSF
Answer: A,E
Explanation:
When implementing Nonstop Routing (NSR) High Availability on an MPLS Provider Edge (PE) router, it's important to consider that NSR generally consumes more memory and CPU resources than Nonstop Forwarding (NSF) because it needs to maintain a stateful switchover capability. Additionally, NSR requires routing protocol extensions to ensure that the state information is correctly synchronized between the active and standby routers, allowing for seamless failover without session loss. This ensures continuous packet forwarding even during a switchover event.

NEW QUESTION # 160
Refer to the exhibit.
An engineer is trying to implement BGP configuration on a router Which configuration error prevents the ASBR from establishing a BGP neighborship to a directly connected BGP speaker?
- A. The TCP session parameters are not specified.
- B. The routing policy is absent for this Cisco IOS XR eBGP instance.
- C. The IPv4 address family configuration under neighbor configuration-mode must be removed.
- D. The VPNv4 address family interferes with the 8GP IPv4 address family negotiations.
Answer: C
Explanation:
The IPv4 address family configuration under neighbor configuration-mode must be removed. The exhibit shows the configuration of a BGP neighborship between an ASBR and a directly connected BGP speaker.
The ASBR is running Cisco IOS XR. The neighbor is configured with the IPv4 address family, which is not supported on Cisco IOS XR. To establish the BGP neighborship, the IPv4 address family configuration must be removed.
