Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 511

How does EIGRP differ from OSPF?

Answer options

• A. EIGRP is more prone to routing loops than OSPF.
• B. EIGRP uses more CPU and memory than OSPF.
• C. EIGRP has a full map of the topology, and OSPF only knows directly connected neighbors.
• D. EIGRP supports equal or unequal path cost, and OSPF supports only equal path cost.

Correct answer: D

Explanation

The correct answer is D because EIGRP can utilize both equal and unequal path costs for routing decisions, which provides more flexibility in load balancing. In contrast, OSPF only supports equal cost multipath routing. Options A, B, and C are incorrect because EIGRP is generally less prone to routing loops, uses less CPU and memory compared to OSPF, and both protocols maintain a view of the network topology, albeit in different ways.
