ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 57
What are two drawbacks of implementing a link-state routing protocol? (Choose two.)
Answer options
- A. the sequencing and acknowledgment of link-state packets
- B. the high volume of link-state advertisements in a converged network
- C. the requirement for a hierarchical IP addressing scheme for optimal functionality
- D. the high demand on router resources to run the link-state routing algorithm
- E. the large size of the topology table listing all advertised routes in the converged network
Correct answer: C, D
Explanation
The correct answers are C and D because a link-state routing protocol often requires a hierarchical IP addressing scheme to function efficiently, and it places a significant load on router resources to run the complex algorithms involved. Options A and B do not represent primary drawbacks of link-state protocols, as sequencing and acknowledgment are common to many protocols, and while link-state advertisements can be numerous, they are not inherently a drawback relative to the benefits they provide.
