NEW QUESTION 72
An engineer is designing a Layer 3 campus network running EIGRP between the core, aggregation, and access layers. The access layer switches will be connected to the aggregation layer using Layer 3 copper connections.
The engineer wants to improve convergence time for access layer switch failures. Which technique must the design include?
- A. EIGRP summarization from access to aggregation layer
- B. enabling BFD for EIGRP on the access layer uplinks
- C. reducing the EIGRP Hello / Hold timer values
- D. EIGRP summarization from core to aggregation layer
Answer: B
NEW QUESTION 73
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.

- A. BPDU Skew Detection
- B. root guard
- C. loop guard
- D. BPDU guard

Answer: D
NEW QUESTION 82
An engineer is designing an EIGRP network for a small branch site where there is only one Layer 3 router.
The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?
- A. Use a static default route for this site instead of EIGRP
- B. Advertise the local LAN using the network command and the passive-interface feature
- C. Redistribute the local LAN network using the redistribute connected command
- D. Advertise the local LAN subnet as a stub network
Answer: B
NEW QUESTION 83
A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1.

The new branch office is assigned to area 2. Which OSPF configuration enables all three locations to exchange routes?
- A. A sham link must be configured between the new branch office and HQ
- B. The new branch office must be configured as a stub area
- C. A virtual link must be configured between the new branch office and HQ
- D. The existing branch office must be configured as a stub area
