A.
The tracking return code fails after the SLA operation results in an ICMP echo failure
three times.

B.
The tracking return code fails after the SLA operation results in an ICMP echo failure one
time.

C.
After the tracking object fails, the tracking object moves back to an up state
45 seconds later in all cases.

D.
After moving to a down state, the tracking object moves back to an OK state 45 seconds
after the SLA operation moves to an OK state.

Explanation:
The up timers on the tracking object defines how long to wait, when in a down state, after
seeing the IP SLA object transition to an OK state. Similarly, the down timer defines how
long to wait, when in an OK state, after seeing the IP SLA object move to a down state,
before moving the tracking object to a down state.
