- A
cloudsql.googleapis.com/database/network/received_bytes_count
Why wrong: Network bytes are not directly relevant.
- B
cloudsql.googleapis.com/database/disk/bytes_used
Why wrong: Disk usage is separate; not relevant for CPU alert.
- C
cloudsql.googleapis.com/database/replication/replica_lag
This metric measures replication lag in seconds.
- D
cloudsql.googleapis.com/database/cpu/utilization
This metric tracks CPU usage percentage.
- E
agent.googleapis.com/cpu_usage
Why wrong: This is a generic agent metric, not specific to Cloud SQL.

PCDOE Manage Database Solutions Practice Question
This PCDOE practice question tests your understanding of manage database solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 database administrator wants to set up monitoring and alerting for Cloud SQL instances. They need to be notified when CPU utilisation exceeds 80% for more than 5 minutes and when replication lag on a read replica exceeds 30 seconds. Which two metrics should they create alerting policies for? (Choose TWO.)
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
✓
cloudsql.googleapis.com/database/replication/replica_lag
Cloud SQL provides the metric 'cloudsql.googleapis.com/database/cpu/utilization' for CPU usage and 'cloudsql.googleapis.com/database/replication/replica_lag' for replication lag. Alerting policies can be set on these metrics in Cloud Monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
