1 2373What is "keepalive"? a. A keepalive is a small, layer-1 bit message that is transmitted by a network device to let directly-connected network devices know of its presence. b. A keepalive is a small, layer-2 message that is transmitted by a network device to let directly-connected network devices know of its presence. c. A keepalive is a small, layer-2 message that is transmitted by a network device to let it neighbors know of congestion d. A keepalive is a small, layer-3 message that is transmitted by a network device to let directly-connected network devices know of its presence. e. A keepalive is a small, layer-3 message that is transmitted by a network device to let it neighbors know of congestion
