Answer: A
Explanation: The proper syntax for configuring a second subinterface is interface 0.2 point-to-point. Option A
is the closest to this command. The syntax after the command interface is serial interface number (0 in this
case).subinterface number (2 in this case) and this followed by the either multipoint or point-to-point.
Incorrect Answers:
B is incorrect; remember that the syntax is suppose to be number.subinterface number and that there is suppose
to be two hyphens in point -to-point.
C is incorrect; the command is interface not subinterface.
D is incorrect; the two numbers are broken by a period and not the word sub.
E is incorrect; this is not the proper syntax. Remember the interface and subinterface are identified by
number.subintreface number.
