PCDOE Implementing service monitoring strategies Practice Question
You need to monitor the health of an external HTTP endpoint. Which resource should you create?
⚠ Common exam trap
Google Cloud often tests the distinction between internal health checks (for VMs/backends) and external uptime checks (for public endpoints), so the trap here is that candidates confuse a load balancer health probe (which checks backends) with a tool for monitoring an external HTTP endpoint.

Correct answer & explanation
✓
Uptime check in Cloud Monitoring
To monitor the health of an external HTTP endpoint, you need a service that can reach the endpoint from outside your VPC and provide alerting and visibility. Cloud Monitoring's Uptime Check is specifically designed for this purpose: it verifies that an external HTTP(S) endpoint is reachable and responsive, and can trigger alerting policies based on the results. This is the correct resource because it operates from Google's infrastructure, not from within your project, and directly supports external endpoint monitoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Load balancer with a health probe
Why it's wrong here
This is for internal traffic routing, not external monitoring.
- ✗
Internal health check in Compute Engine
Why it's wrong here
Internal health checks are for load-balanced backends, not external endpoints.
- ✓
Uptime check in Cloud Monitoring
Why this is correct
Uptime checks monitor external endpoints for availability.
- ✗
Cloud Logging log-based metric
Why it's wrong here
Log-based metrics count log entries, not endpoint health.
