CV0-004 Operations and Support Practice Question
A cloud operations team wants to implement automated patching for their fleet of virtual machines. They need to minimize disruption during business hours and ensure that critical security patches are applied within 48 hours of release. The team also requires a rollback plan in case a patch causes issues. Which THREE actions should the team take? (Choose three.)
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
✓
Define maintenance windows that occur during off-peak hours.
Automated patching requires defining maintenance windows to avoid disruption, enabling automated patching tools like AWS Systems Manager Patch Manager, and having a rollback procedure in place. Testing patches in a staging environment first is wise but not a direct action for the described requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Define maintenance windows that occur during off-peak hours.
Why this is correct
Maintenance windows minimize disruption by scheduling patching during low-usage periods.
- ✓
Document rollback procedures to revert patches if necessary.
Why this is correct
Rollback procedures are essential for recovering from problematic patches.
- ✗
Disable automatic updates to maintain control over patch deployment.
Why it's wrong here
Disabling updates would delay critical patches and is contrary to automation.
- ✓
Enable automated patching using a tool such as AWS Systems Manager Patch Manager.
Why this is correct
Automated patching tools manage patch deployment across the fleet.
- ✗
Apply all patches immediately upon release regardless of maintenance windows.
Why it's wrong here
This would cause disruption; patches should be applied during maintenance windows.
