- A
Place all resources in the same zone to simplify management
Why wrong: Same zone does not provide zone-level fault tolerance.
- B
Use a regional managed instance group for the web frontend
Regional MIG distributes instances across multiple zones.
- C
Use a Cloud SQL for PostgreSQL instance with cross-zone replication
Cloud SQL with cross-zone replication provides high availability.
- D
Configure the database as a single large instance with automatic backups
Why wrong: Single instance is not highly available; backups do not provide failover.
- E
Deploy the web frontend in a single zone to reduce network latency
Why wrong: Single zone introduces a single point of failure.

Cloud Digital Leader Fundamental Cloud Concepts Practice Question
This GCDL practice question tests your understanding of fundamental cloud concepts. 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 wants to deploy a multi-tier web application on Google Cloud that requires high availability across zones. The application consists of a stateless web frontend and a stateful database backend. Which TWO actions should the company take to meet the high availability requirement? (Select 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
✓
Use a regional managed instance group for the web frontend
To achieve high availability across zones, the frontend should be deployed in multiple zones behind a load balancer, and the database should be configured with replication across zones. Using a single large instance for the database creates a single point of failure. Regional managed instance groups distribute instances across zones.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
