A switch runs Open Shortest Path First (OSPF) on an interface and needs to establish an OSPF
adjacency or adjacencies on that interface. In which situation should the architect pay particular
attention to the OSPF hello timer and possibly tune it to a lower value?
A.
when spanning tree is disabled on the switch
B.
when the interface is a VLAN interface that does not implement Virtual Router Redundancy
Protocol (VRRP)
C.
when the interface is a VLAN interface associated with an indirect connection to a single OSPF
peer router
D.
when the interface is a direct physical link to a single OSPF peer router
Answer is C – confirmed with study guide:
Section “Minimize Convergenve Time”
“If a link is indirect and also might have multiple neighbors… consider the need for Bidirectional Forwarding Detection (BFD). When you cannot use BFD, you can still obtain relatively fast converge by setting the hello timer as low as possible.”
