PCDOE Implementing service monitoring strategies Practice Question
This PCDOE practice question tests your understanding of implementing service monitoring strategies. 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.
A company needs to monitor custom application metrics from Compute Engine instances. Which TWO methods can be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Install Cloud Monitoring agent on instances
Option B is correct because the Cloud Monitoring agent is specifically designed to collect custom application metrics from Compute Engine instances and send them to Cloud Monitoring. It supports both third-party applications and custom metrics via its built-in integration with collectd and a configuration interface for defining custom metrics. This is the standard, supported method for monitoring custom metrics from VMs.
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.
✗
Use the deprecated Stackdriver Agent
Why it's wrong here
The Stackdriver Agent is deprecated and should not be used.
✓
Install Cloud Monitoring agent on instances
Why this is correct
The agent collects custom metrics and sends to Cloud Monitoring.

✗
Use Cloud Trace
Why it's wrong here
Cloud Trace is for distributed tracing, not custom metrics.
✓
Use OpenTelemetry to send metrics to Cloud Monitoring
Why this is correct
OpenTelemetry is a supported standard for custom metrics.

✗
Install Cloud Logging agent
Why it's wrong here
The Logging agent collects logs, not metrics.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between agents for logging versus monitoring, and candidates mistakenly think the Cloud Logging agent can also handle metrics, or they confuse Cloud Trace (tracing) with metric collection.
Detailed technical explanation
How to think about this question
The Cloud Monitoring agent uses an embedded collectd daemon to collect system and application metrics, and it can be configured via a YAML file to scrape custom metrics from applications (e.g., via a statsd endpoint or a custom plugin). Under the hood, the agent writes metrics to the Cloud Monitoring API using the `monitoring.googleapis.com` endpoint, which then stores them as custom metric descriptors. In a real-world scenario, you might deploy the agent on a Compute Engine instance running a web server and configure it to report request latency as a custom metric, which can then be used to create alerting policies.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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
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.
