Question 59/132
Which of the following are features of the OSPF protocol?
Correct Answer: B,D
Detailed Explanation:
* Option B: OSPF supports triggered updates, allowing routing tables to be updated only when changes occur, conserving bandwidth.
* Option D: OSPF supports area division, which is essential for optimizing large networks and limiting the scope of link-state advertisements.
* Option A is incorrect because OSPF calculates the shortest path based on cost, not hop count.
* Option C is incorrect; OSPF prevents routing loops by maintaining a loop-free topology through its link-state database.
