Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 750

In which way are EIGRP and OSPF similar?

Answer options

• A. Both protocols support autosummarization.
• B. Both protocols use hello packets to discover neighbors.
• C. Both protocols support unequal-cost load balancing.
• D. Both protocols send updates using unicast addresses.

Correct answer: B

Explanation

The correct answer is B, as both EIGRP and OSPF employ hello packets to establish and maintain neighbor relationships. Option A is incorrect because EIGRP supports autosummarization while OSPF does not. Option C is wrong because while EIGRP does support unequal-cost load balancing, OSPF does not. Option D is also incorrect; OSPF typically uses multicast addresses for its updates, not unicast.
