CV0-004 Operations and Support Practice Question
A cloud administrator notices that an Auto Scaling group is launching and terminating instances too frequently, causing instability. What should the administrator adjust to reduce this flapping behavior?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the cooldown period
Increasing the cooldown period gives instances time to stabilize before additional scaling actions, reducing flapping.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable the cooldown period
Why it's wrong here
Removing the cooldown period lets the Auto Scaling group evaluate and act on alarms continuously, so instances launch and terminate on every brief metric fluctuation — the exact flapping cause. Cooldown exists to pause scaling after an action; disabling it suits environments needing immediate, aggressive response, not stability.
- ✗
Decrease the cooldown period
Why it's wrong here
Shortening the cooldown period reduces the pause between scaling actions, so the group reacts to transient metric spikes and terminates instances it just launched, worsening flapping. A longer cooldown is what damps this oscillation. Short cooldowns suit workloads needing rapid capacity response to genuine, sustained demand shifts.
- ✗
Increase the scale-out threshold
Why it's wrong here
Raising the scale-out threshold delays adding capacity, so the group still terminates instances on the low-side breach that actually drives flapping; it addresses the wrong trigger. Threshold tuning suits steady demand shaping, not oscillation damping. The cooldown period is the mechanism that suppresses repeated scaling actions.
- ✓
Increase the cooldown period
Why this is correct
The cooldown period prevents the Auto Scaling group from launching or terminating additional instances immediately after a scaling activity, damping rapid oscillation. Increasing it forces the group to wait longer between actions, directly reducing the flapping instability described.
