Q: 11
A network architect must redesign a data center network based on OSPFv2. The network must perform fast
reconvergence between directly connected switches. Which two actions must be taken to meet the requirements?
(Choose two.)

C and E tbh. BFD (C) is what Cisco wants for fast, subsecond detection, and OSPF point-to-point (E) reduces convergence time since the topology's simpler. Pretty confident but open to other takes.
Option C and E make sense here. BFD is known for fast failure detection, and point-to-point links speed up OSPF convergence. Not totally certain, but saw similar on practice exams. Agree?
Would labbing this with BFD and point-to-point configs help clarify? I’ve seen similar reconvergence Qs pop up in official Cisco practice exams lately.
Had something like this in a mock and picked C and E. BFD (C) is used for subsecond failure detection with OSPF, while point-to-point links (E) simplify the topology, both speeding up convergence. If anyone disagrees let me know, but pretty sure that's Cisco's expected answer.
C vs B but I’m picking C and E here. B is tempting since lowering hello/dead timers does help, but Cisco exam style favors BFD (C) for subsecond detection and E’s point-to-point links cut down on convergence complexity. Don’t think A or D get you any faster reconvergence directly.
Its C and E. BFD (C) is designed for rapid failure detection, much quicker than OSPF timers alone, and point-to-point links (E) let OSPF converge faster because there’s less ambiguity in the topology. Low hello/dead timers (B) help too, but BFD’s even faster and less intensive on resources. I think C/E aligns best with how Cisco wants you to answer this.
C and E tbh. BFD gives you really quick failure detection with OSPF and point-to-point links help with faster convergence too. I’ve seen similar in practice exams, so pretty sure this is right.
Be respectful. No spam.
