This PCDOE practice question tests your understanding of optimizing service performance. This is a configuration task: choose the command set that satisfies every stated requirement. 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.
Which service should be used to monitor the health of HTTP endpoints from multiple locations?
Cloud Trace
Why wrong: Cloud Trace traces requests, not health checks.
Cloud Logging
Why wrong: Cloud Logging stores logs, not health checks.
Cloud Monitoring
Correct. Uptime checks in Cloud Monitoring monitor endpoint health.
Cloud Debugger
Why wrong: Cloud Debugger inspects code state, not health.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Cloud Monitoring
Cloud Monitoring (formerly Stackdriver Monitoring) includes uptime checks that can be configured to probe HTTP endpoints from multiple global locations, measuring latency, availability, and response content. This makes it the correct service for monitoring the health of HTTP endpoints from diverse geographic regions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Cloud Trace
Why it's wrong here
Cloud Trace traces requests, not health checks.
Cloud Logging
Why it's wrong here
Cloud Logging stores logs, not health checks.
Cloud Monitoring
Why this is correct
Correct. Uptime checks in Cloud Monitoring monitor endpoint health.

Cloud Debugger
Why it's wrong here
Cloud Debugger inspects code state, not health.
Common exam traps
Google Cloud often tests the distinction between passive monitoring (Cloud Logging) and active synthetic monitoring (Cloud Monitoring uptime checks), leading candidates to mistakenly choose Cloud Logging because they think 'health' implies analyzing logs rather than proactively probing endpoints.
Detailed technical explanation
Cloud Monitoring uptime checks use a configurable list of locations (e.g., us-west1, europe-west1, asia-east1) to send HTTP(S) requests at intervals as low as 1 minute, validating status codes (e.g., 200-299) and optional response content via regex. These checks generate metrics like `check_passed` and `latency`, which can trigger alerting policies based on conditions such as a 95% failure rate over 5 minutes. In a real-world scenario, a global e-commerce site might use uptime checks from 10+ locations to detect regional outages before they impact all users.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
