Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 542

In which way are EIGRP and OSPF similar?

Answer options

• A. They both support unequal-cost load balancing.
• B. They both support MD5 authentication for routing updates.
• C. They both support autosummarization.
• D. They have similar CPU usage, scalability, and network convergence times.

Correct answer: B

Explanation

The correct answer is B because both EIGRP and OSPF utilize MD5 authentication to secure routing updates, enhancing the integrity and security of the routing information exchanged. Options A, C, and D are incorrect as EIGRP supports unequal-cost load balancing, while OSPF does not; autosummarization is not supported by OSPF; and the CPU usage, scalability, and convergence times can vary significantly between the two protocols.
