Designing Cisco Network Service Architectures (ARCH, legacy) — Question 54

EIGRP uses which algorithm to build a routing table?

Answer options

• A. Dijkstra's algorithm
• B. Floyd-Warshall algorithm
• C. Diffusing Update Algorithm
• D. Johnson's algorithm

Correct answer: C

Explanation

EIGRP employs the Diffusing Update Algorithm (DUAL) to efficiently manage its routing table, allowing for rapid convergence. The other algorithms listed, such as Dijkstra's and Floyd-Warshall, are used in different routing protocols but are not applicable to EIGRP.
