Answer options
- A. router bgp 1.0 bgp router-id 1.1.1.1 no bgp default Ipv4-unlcast bgp fast-external-fallover timers keep-alive 40 timers hold 120
- B. router bgp 1.0 bgp router-id 1.1.1.1 no bgp default ipv4-unicast bgp fast-external-fallover timers bgp 40 60
- C. router bgp 1.0 bgp router-id 1.1.1.1 no bgp default ipv4-unicast bgp fast-external-fallover timers keep-alive 40 timers hold 60
- D. router bgp 1.0 bgp router-id 1.1.1.1 no bgp default ipv4-unicast bgp fast-external-fallover timers bgp 40 120
Correct answer: D
Explanation
The correct answer is D because it sets the BGP timers to 40 seconds for keep-alive and 120 seconds for hold time, which aligns with best practices for BGP configuration. Options A and C incorrectly set hold times or keep-alive intervals that do not follow recommended BGP timer values, while option B uses the 'timers bgp' command with incorrect values that do not adhere to the guidelines.
