The correct answer is that Azure Auto-Shutdown provides automatic daily power-off of VMs at a configured time to reduce costs. This feature directly addresses the search intent of Azure auto-shutdown virtual machines cost saving by allowing you to schedule a specific time, such as 7 PM each evening, when non-essential VMs are automatically turned off, stopping compute billing while leaving the VM’s configuration and disks intact. On the AZ-900 exam, this tests your understanding of cost management tools within Azure, often appearing in questions about reducing operational expenses without deleting resources. A common trap is confusing auto-shutdown with auto-deletion or deallocation of storage—remember, auto-shutdown only powers off the VM, preserving all settings and data. For a memory tip, think of it as a “smart timer” for your wallet: it stops the meter, not the machine.

Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
What does Azure Auto-Shutdown for virtual machines provide?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Automatic daily power-off of VMs at a configured time to reduce costs
Azure Auto-Shutdown is a cost-saving feature that automatically powers off virtual machines at a user-defined schedule (e.g., nightly at 7 PM). It helps reduce compute costs by ensuring VMs are not running when not needed, but does not delete or modify the VM's configuration or resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Automatic deletion of VMs that haven't been used for 30 days
Why it's wrong here
Auto-Shutdown schedules daily power-off; it doesn't delete VMs based on inactivity.
✓
Automatic daily power-off of VMs at a configured time to reduce costs
Why this is correct
VM Auto-Shutdown powers off VMs at a scheduled time daily, stopping compute billing for dev/test savings.
Related concept
Read the scenario before looking for a memorised answer.
✗
Automatic scaling down of VM CPU when under low utilization
Why it's wrong here
CPU scaling is handled by Autoscale or resizing; Auto-Shutdown turns the VM completely off.
✗
Automatic failover of VMs to another region during outages
Why it's wrong here
Failover is handled by Azure Site Recovery; Auto-Shutdown is simply a daily power-off schedule.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'shutting down' with 'deleting' or 'scaling'—Azure Auto-Shutdown only powers off the VM, it does not remove the VM or adjust its performance characteristics.
Detailed technical explanation
How to think about this question
Auto-Shutdown works by sending a shutdown signal to the VM's operating system via the Azure fabric controller, which triggers a graceful OS-level shutdown (ACPI power-off). The VM remains in a 'Stopped (Deallocated)' state, meaning compute resources are released and no longer billed, but attached disks and IP addresses are preserved. This is distinct from 'Stopped (Allocated)' where compute resources are still reserved and incur charges.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
