Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SSH into the instance and run 'free -m' to check memory usage
Why this is correct
Running commands directly on the instance gives real-time memory usage.
- ✓
Check Cloud Logging for OOM (out-of-memory) kernel messages
Why this is correct
OOM messages are logged in Cloud Logging and can confirm memory exhaustion.
- ✗
Increase the instance's memory by changing the machine type
Why it's wrong here
Changing the machine type is a fix, not a diagnostic action.
- ✗
Create a snapshot of the boot disk
Why it's wrong here
Snapshot is for backup, not troubleshooting memory issues.
- ✓
View the instance's memory utilization metric in Cloud Monitoring
Why this is correct
Cloud Monitoring provides memory utilization metrics for Compute Engine.
