Refer to the exhibits.
The network administrator enters the commands shown in Exhibit 2, and Switch-1 and Switch-2 exchange keepalive messages. What is the expected behavior if Switch-1 later fails to receive keepalive messages from Switch-2?
A. Switch-1 disables interface 1 for 10 seconds, and then re-enables it. The same process repeats twice. If the issue persists, the switch disables the interface permanently.
B. After two consecutive missed keep-alive packets, Switch-1 disables interface 1, and the interface stays disabled until the issue is fixed.
C. After two consecutive missed keep-alive packets, Switch-1 sends SNMP traps, and Link 1 stays up until the issue is fixed.
D. Switch-1 disables interface 1 for 10 seconds and then re-enables it. The interface continues to be re-enabled and disabled every 10 seconds until the issue is fixed.
