- A
Take a full backup of the on-premises database and restore it to RDS during a maintenance window.
Why wrong: This causes significant downtime.
- B
Use AWS Direct Connect to establish a dedicated network connection for faster data transfer.
Why wrong: Direct Connect improves speed but does not minimize downtime by itself.
- C
Increase the allocated storage on the target RDS instance to improve write performance.
Why wrong: Storage increase does not directly minimize migration downtime.
- D
Use AWS Schema Conversion Tool (SCT) to convert the schema and optimize for RDS.
SCT helps convert schema and identify potential issues, reducing downtime.
- E
Use AWS Database Migration Service (DMS) with ongoing replication to keep the target in sync.
Ongoing replication allows near-zero downtime cutover.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 planning to migrate its on-premises Oracle database to Amazon RDS for Oracle. Which actions should the company take to minimize downtime during the migration? (Choose TWO.)
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
Use AWS Schema Conversion Tool (SCT) to convert the schema and optimize for RDS.
Option A (use AWS DMS with ongoing replication) and Option D (use AWS SCT for schema conversion) are correct. Option B (take a full backup and restore) causes downtime. Option C (use Direct Connect for faster transfer) is helpful but not specifically for minimizing downtime. Option E (increase instance size) is not directly related.
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.

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 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 SAP-C02 ACL questions on filtering logic and placement.
