PCDOE Migrate Database Solutions Practice Question
This PCDOE practice question tests your understanding of migrate database solutions. 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.
An organization is migrating an Oracle database to Cloud SQL for PostgreSQL. They have numerous stored procedures written in PL/SQL. Which tool should they use to automatically convert these procedures to PL/pgSQL?

Correct answer & explanation
✓
Ora2Pg
Ora2Pg is a schema conversion tool that translates Oracle PL/SQL code to PostgreSQL PL/pgSQL, handling data type mappings and object conversions.
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.

BigQuery Data Transfer Service
Why it's wrong here
This service is for loading data into BigQuery, not for Oracle to PostgreSQL migration.
- ✗
Database Migration Service (DMS)
Why it's wrong here
DMS handles data migration but does not automatically convert stored procedures.
- ✗
gcloud sql import
Why it's wrong here
This command imports data into Cloud SQL but does not perform schema conversion.
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.
Trap categories for this question
Command / output trap
This command imports data into Cloud SQL but does not perform schema conversion.
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 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.
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 PCDOE ACL questions on filtering logic and placement.
