In an OSPF network with routers connected together with Ethernet cabling, which topology typically takes...

In OSPF, a ring topology typically converges more slowly because:

Link failures can create longer SPF recalculations as alternate paths are fewer.

Only one alternate path usually exists for each link failure, extending the time needed for failure detection and SPF recalculation.

CCDE v3.1 stresses that designs like full mesh or triangulated topologies provide faster convergence due to multiple available alternate paths, which reduce SPF computation complexity.

Why other options are incorrect:

A, D, E: These topologies provide multiple paths.

B: Full mesh offers immediate redundancy for any failure.
