Assume that the following commands are run to configure BGP

timer keepalive 30 hold 90

peer 1.1.1.2 timer keepalive 10 hold 30

Which statements regarding the configuration are true? (Select 2 answers)

AA global configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are 'keepalive 30 hold 90.'

BA peer configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are 'keepalive 10 hold 30.'

CThe smaller value between the global and peer timer values is chosen. Therefore, the timer values for peer 1.1.1.2 are 'keepalive 10 hold 30'.
