- A
Cloud SQL for MySQL
Why wrong: MySQL is an option but may require significant code changes if the application uses Oracle-specific features.
- B
Cloud Spanner
Why wrong: Spanner is globally distributed and more expensive than necessary for a single-region migration.
- C
Bare Metal Solution for Oracle
Why wrong: Bare Metal Solution runs Oracle on dedicated hardware, which does not reduce licensing costs.
- D
Cloud SQL for PostgreSQL
PostgreSQL is a robust open-source database with many features similar to Oracle; Cloud SQL offers fully managed HA at lower cost.

Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Question
This GCDL practice question tests your understanding of why cloud technology can transform business. 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 company is migrating its on-premises Oracle database to Google Cloud. They want to minimize licensing costs and use a fully managed database service with high availability. Which database should they choose?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
✓
Cloud SQL for PostgreSQL
Cloud SQL for PostgreSQL is a fully managed, cost-effective alternative to Oracle, with built-in high availability (regional replicas) and no licensing fees.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud SQL for MySQL
Why it's wrong here
MySQL is an option but may require significant code changes if the application uses Oracle-specific features.
- ✗
Cloud Spanner
Why it's wrong here
Spanner is globally distributed and more expensive than necessary for a single-region migration.
- ✗
Bare Metal Solution for Oracle
Why it's wrong here

- ✓
Cloud SQL for PostgreSQL
Why this is correct
PostgreSQL is a robust open-source database with many features similar to Oracle; Cloud SQL offers fully managed HA at lower cost.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related GCDL ACL questions on filtering logic and placement.
