Answer: A
NEW QUESTION # 100
Refer to the exhibit.
An engineer is designing a routing solution for a customer. The design must ensure that a failure of network
10.1.0.0/24, 10.1.2.0/24, 10.2.1.0/24, or 10.2.3.0/24 does not impact the core. It also requires fast convergence time during any link failover in the core or access networks. Which solution must the engineer select?
- A. Enable summarization on routers A and C.
- B. Add aggregation layer between core and access networks.
- C. Enable graceful restart on routers A and C.
- D. Enable FRR for the connected networks of routers A and C.
Answer: D
NEW QUESTION # 101
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
- A. Empty data subscriptions do not generate empty update notifications.
- B. The primary push update is sent immediately and cannot be delayed.
- C. Updates that contain changes within the data are sent only when changes occur.
- D. Periodic updates include a full copy of the data that is subscribed to.
Answer: D

NEW QUESTION # 102
Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?
- A. Configure a higher mac-refresh interval on both HSRP devices
- B. Increase the hello timers on both HSRP devices
- C. Use the preempt delay feature on the backup HSRP device
- D. Use the preempt delay feature on the primary HSRP device.

NEW QUESTION # 104
A network engineer must design an MSDP multicast solution to provide RP resilience in a network with two separate domains. Also, multicast sources and receivers must register with the local RP. Which solution must the engineer choose?
- A. Configure the RP priority with the same value, and traffic will route to the closest RP
- B. Configure the RP group ranges to split the multicast traffic, and traffic will route to the longest match
- C. Configure the RP loopback interface with the same IP address/32, and traffic will route to the closest RP
- D. Configure the RP has value to 0, and traffic will route to the closest RP
