CV0-004 Automatic recovery Practice Question
A cloud administrator is responsible for ensuring the availability of a critical application that runs on a virtual machine. The administrator needs to implement a solution that can automatically restart the virtual machine if it becomes unresponsive due to an operating system crash. Which of the following should the administrator configure?
⚠ Common exam trap
A common mix-up: candidates confuse a load balancer's health probe (which only reroutes traffic) with automatic VM recovery, or they assume a custom heartbeat script alone is sufficient without understanding that it lacks the built-in execution engine to perform the restart.
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
✓
A VM group configured with automatic recovery
Configuring automatic recovery for the VM (or a group of VMs) allows the cloud platform to detect a VM failure and automatically restart it. This is a feature provided by most cloud providers to ensure high availability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A snapshot-based backup policy
Why it's wrong here
Snapshots capture point-in-time disk state for recovery, but they do not detect an OS crash or trigger a restart. It is tempting because backups restore failed workloads, yet restoration is manual and data-focused, whereas the scenario requires automatic detection and restart of the unresponsive VM.
- ✗
A load balancer with a health probe
Why it's wrong here
A health probe detects an unresponsive application and removes the VM from rotation, but it cannot restart the guest OS; that requires an availability-set or VMSS health extension or Azure Site Recovery. Load balancers suit distributing traffic across healthy instances, not remediating a crashed operating system.
- ✓
A VM group configured with automatic recovery
Why this is correct
A VM group with automatic recovery monitors guest health and restarts the virtual machine when the operating system stops responding, satisfying the requirement to recover automatically from an OS crash. Unlike host-level HA, which only reacts to physical host failure, this detects in-guest unresponsiveness and triggers the restart.
- ✗
A custom script that sends a heartbeat to a monitoring service
Why it's wrong here
A heartbeat script only detects unresponsiveness; it cannot restart the VM, so it fails the automatic recovery requirement. It is tempting because heartbeats underpin health monitoring, and would suit alerting an operator, but the scenario demands an automated restart action the script never performs.
