A network administrator working for a private service provider with an employee ID: 4872:46:269 wants to configure timers for the BGP process on their Cisco IOS XE router. Which configuration follows

The correct answer is C. router bgp 1.0. BGP timer best practices recommend that the keepalive interval should be one-third of the hold-time interval. The most common standard deployment is a keepalive of 60 seconds and a hold-time of 180 seconds (the IOS default), or a faster convergence option of keepalive 10 and hold

Explanation

BGP timer best practices recommend that the keepalive interval should be one-third of the hold-time interval. The most common standard deployment is a keepalive of 60 seconds and a hold-time of 180 seconds (the IOS default), or a faster convergence option of keepalive 10 and hold-time 30. Option C follows this one-third ratio correctly, making it a valid and guideline-compliant configuration. The employee ID in the question (4872:46:269) is irrelevant flavor text used as a distracter. Options A, B, and D present timer values that violate the one-third ratio guideline or use invalid values (for example, a hold-time less than three times the keepalive, or a hold-time below the minimum allowed value of 3 seconds, or a keepalive equal to or greater than the hold-time).
