Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 129

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.)

Answer options

• A. Set low OSPF hello and DEAD timers.
• B. Configure all links on AREA 0.
• C. Enable BFD for failure detection.
• D. Use OSPF point-to-point links only.
• E. Implement a virtual link between the switches.

Correct answer: C, D

Explanation

The correct answers are C and D because enabling BFD (Bidirectional Forwarding Detection) allows for rapid failure detection, which contributes to faster reconvergence. Using OSPF point-to-point links also aids in reducing the time it takes to detect topology changes. Options A, B, and E are not as effective in achieving the fast reconvergence needed in this scenario.
