ACE Practice Question: A financial application requires all database…
This ACE practice question tests your understanding of a financial application requires all database…. 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.
A financial application requires all database transactions to be durable even if the primary Cloud SQL instance fails mid-transaction. The RPO (Recovery Point Objective) must be near-zero. Which Cloud SQL feature achieves this?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Cloud Spanner — it automatically replicates synchronously across zones
Cloud Spanner is a valid option for strong consistency, but the question asks specifically about Cloud SQL features — HA is the Cloud SQL answer.
B
Best answer
Cloud SQL High Availability with synchronous standby replica in a different zone
Cloud SQL HA uses synchronous replication — each transaction is written to both primary and standby before commit acknowledgment. Primary failure results in zero data loss (near-zero RPO).
C
Distractor review
Cloud SQL with automated daily backups and point-in-time recovery
Automated backups allow recovery to a point in time, but the RPO equals the time since the last backup or log — not near-zero for mid-transaction failures.
D
Distractor review
Cloud SQL read replica with synchronous replication
Cloud SQL read replicas use asynchronous replication — there's a replication lag, so the RPO is not zero. They're for read scaling, not zero-RPO HA.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Cloud SQL High Availability with synchronous standby replica in a different zone — Cloud SQL High Availability uses synchronous replication to a standby replica in a different zone. Every transaction is committed to both the primary and standby before being acknowledged, ensuring zero data loss on primary failure. Read replicas use asynchronous replication and may have some data loss on failover.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
