What is the default HSRP priority?
A . 50
B . 100
C . 120
D . 1024

Answer: B

Explanation:

standby [group-num- Set a priority value used in choosing the active router. The ber] priority priority range is 1 to 255; the default priority is 100. The highest [preempt [delay delay]] number represents the highest priority. (Optional) group-number–The group number to which the command applies. (Optional) preempt–Select so that when the local router has a higher priority than the active router, it assumes control as the active router. (Optional) delay–Set to cause the local router to post- pone taking over the active role for the shown number of seconds. The range is 0 to 36000 (1 hour); the default is 0 (no de- lay before taking over). Use the no form of the command to restore the default values.
