Exam 300-420 topic 1 question 61 discussion

Actual exam question from Cisco's 300-420

Question #: 61
Topic #: 1

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 the convergence time for access layer switch failures.
Which technique must the design include?

A. enabling BFD for EIGRP on the access layer uplinks
B. reducing the EIGRP Hello / Hold timer values
C. EIGRP summarization from core to aggregation layer
D. EIGRP summarization from access to aggregation layer

Selected Answer: A

The correct answer is A. enabling BFD for EIGRP on the access layer uplinks. Bidirectional Forwarding Detection (BFD) is a protocol used to quickly detect failures in the forwarding path between two adjacent devices. By enabling BFD for EIGRP on the access layer uplinks, the engineer can significantly improve the convergence time for access layer switch failures. BFD works independently of the routing protocol and can provide faster failure detection than relying on routing protocol timers alone.
