350-401 Question #851: Real Exam Question with Answer & Explanation

The correct arrangement maps EIGRP characteristics to their proper descriptions: OSPF 'quickly computes new path upon link failure' using the SPF (Dijkstra) algorithm, EIGRP 'maintains alternative loop-free backup path if available' via its Feasible Successor concept, and EIGRP '

Question

Drag and Drop Question Drag and drop the characteristics from the left onto the routing protocols they describe on the right. Answer:

Explanation

The correct arrangement maps EIGRP characteristics to their proper descriptions: OSPF 'quickly computes new path upon link failure' using the SPF (Dijkstra) algorithm, EIGRP 'maintains alternative loop-free backup path if available' via its Feasible Successor concept, and EIGRP 'selects routes using the DUAL algorithm' - the Diffusing Update Algorithm that is the cornerstone of EIGRP's route computation and loop-prevention mechanism. The DUAL algorithm is exclusive to EIGRP and enables both the successor and feasible successor selection, making all three characteristics interconnected with EIGRP's design while SPF-based rapid reconvergence is associated with link-state protocols like OSPF.
