- A
Convert to Cloud SQL for PostgreSQL
PostgreSQL is open-source, eliminating Oracle license fees.
- B
Migrate to Firestore
Why wrong: Firestore is a NoSQL document database, not suitable for relational workloads.
- C
Use Database Migration Service (DMS) for homogenous migration
Why wrong: DMS only helps with migration, not reduction of licensing costs.
- D
Use Bare Metal Solution for Oracle
Bare Metal Solution allows running Oracle on dedicated hardware, reducing license costs compared to on-prem.
- E
Migrate to Cloud Spanner
Spanner is a fully managed relational database with no Oracle licensing.

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 a large on-premises Oracle database to Google Cloud. They want to reduce licensing costs and modernize the architecture. Which THREE strategies should they consider? (Choose 3)
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
✓
Convert to Cloud SQL for PostgreSQL
Migrating to Cloud Spanner avoids Oracle licensing and provides horizontal scaling. Bare Metal Solution is for lift-and-shift without modernization. Converting to Cloud SQL for PostgreSQL reduces license costs but may require schema changes. Option D is for migration tooling, not a long-term strategy; option E is a different database type.
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.

Related concept

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.
