CCDE: Cisco Certified Design Expert (Written) — Question 27

Which two OSPF design considerations should you implement to support the eventual growth of a network, so that CPU and memory are unaffected by the size and complexity of the link-state database in a large service provider network? (Choose two.)

Answer options

• A. Turn on route dampening.
• B. Create network summaries.
• C. Turn on the Incremental SPF feature.
• D. Add more memory.
• E. Turn on packet pacing.
• F. Add redundancy between critical locations.

Correct answer: C, E

Explanation

The correct answers are C and E because enabling the Incremental SPF feature allows for more efficient recalculations of the OSPF topology, reducing CPU load, while packet pacing helps manage the flow of OSPF updates, preventing memory overload. The other options, while useful in different contexts, do not directly address the specific concerns of CPU and memory efficiency related to link-state database size and complexity.
