CCDE: Cisco Certified Design Expert (Practical) — Question 179

Which two statements describe the functionality of OSPF packet-pacing timers? (Choose two.)

Answer options

• A. The group-pacing timer controls the interval that is used for group and individual LSA refreshment.
• B. OSPF flood-pacing timers allow dynamic control of the OSPF transmission queue size.
• C. OSPF retransmission-pacing timers allow control of packet interleaving between nonconsecutive link-state update packets in the OSPF retransmission queue.
• D. OSPF flood-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF transmission queue.
• E. OSPF retransmission-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF retransmission queue.

Correct answer: D, E

Explanation

The correct answers, D and E, accurately describe the functions of OSPF flood-pacing and retransmission-pacing timers regarding packet spacing in their respective queues. Options A, B, and C do not correctly represent the specific functionalities of OSPF packet-pacing timers, as they either misinterpret the timer roles or mix up the queue management aspects.
