Which connection uses the default encapsulation for serial interfaces on Cisco routers?
Correct Answer: B
Explanation/Reference:
Explanation:
Cisco default encapsulation is HDLC which is by default enabled on all cisco router. If we want to enable
other encapsulation protocol (PPP,X.25 etc) we need to define in interface setting. But here except s1/1 all
interface defined by other encapsulation protocol so we will assume default encapsulation running on s1/1
interface and s1/1 interface connected with North.
