CCDE: Cisco Certified Design Expert (Practical) — Question 43

In an OSPF network with routers connected together with Ethernet cabling, which topology typically takes the longest to converge?

Answer options

• A. squared
• B. ring
• C. partial mesh
• D. triangulated
• E. full mesh

Correct answer: B

Explanation

The correct answer is B, as a ring topology can lead to longer convergence times due to the circular nature of connections, which can create delays in recognizing link failures. In contrast, topologies like full mesh and partial mesh allow for multiple paths and quicker failure recovery, leading to faster convergence.
