CV0-004 Practice Question: A cloud administrator is tasked with reducing…
A cloud administrator is tasked with reducing costs for a development environment that runs 24/7. The environment consists of several virtual machines and a load balancer. Which action would most effectively reduce costs without affecting developer access during business hours?
⚠ Common exam trap
A common mix-up: candidates choose auto-scaling or burstable instances because they focus on reducing per-unit cost rather than eliminating runtime, missing the fact that shutting down VMs entirely during off-hours yields the greatest savings for a development environment with predictable idle periods.
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
✓
Schedule the VMs to shut down during nights and weekends.
Scheduling VMs to shut down during nights and weekends directly reduces compute costs by eliminating runtime charges when the development environment is not needed. This approach preserves full availability during business hours without requiring architectural changes, and it is the most straightforward way to cut costs for a 24/7-running environment that only needs daytime access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Implement auto-scaling to run only one instance during off-hours.
Why it's wrong here
Auto-scaling to one instance still incurs compute costs 24/7, though reduced.
- ✓
Schedule the VMs to shut down during nights and weekends.
Why this is correct
Correct. Shutting down VMs eliminates compute costs during idle periods, directly reducing expenses.
- ✗
Use reserved instances for all VMs.
Why it's wrong here
Reserved instances require upfront commitment and may not be cost-effective for a dev environment that can be turned off.
- ✗
Change all VMs to burstable instance types.
Why it's wrong here
Burstable instances may not suit all workloads and might not provide sufficient cost savings.
