Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
This PCA practice question tests your understanding of managing implementation and ensuring solution and operations reliability. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Your organization runs a production Cloud SQL for PostgreSQL instance. You need to ensure that if the primary zone fails, the database automatically fails over to a standby with no data loss. Which configuration should you use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy a regional Cloud SQL instance with high availability
Cloud SQL HA with regional instances uses synchronous replication to a standby in a different zone, ensuring zero data loss on automatic failover. Cross-region replication is for disaster recovery, not automatic failover. Point-in-time recovery is for restoration to a specific time, not failover. Read replicas are for read scaling, not automatic failover.
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.
✗
Enable point-in-time recovery (PITR)
Why it's wrong here
PITR enables recovery to a specific time, not automatic failover.
✗
Configure a cross-region replica
Why it's wrong here
Cross-region replicas are for disaster recovery, not automatic failover within the same region.
✓
Deploy a regional Cloud SQL instance with high availability
Why this is correct
Regional HA instances automatically fail over to a standby in another zone with synchronous replication, ensuring no data loss.
Clue confirmation
The clue word "primary" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create a read replica and promote it on failure
Why it's wrong here
Read replicas are asynchronous and promoting may cause data loss; not automatic.
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
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.
