This PAS-C01 practice question tests your understanding of migration. 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 moving their SAP Business One application from an on-premises data center to AWS. The application runs on Windows Server and uses Microsoft SQL Server. They want to use Amazon EC2 for the application and Amazon RDS for SQL Server for the database. They have already used AWS SCT to assess the database schema and found that it is compatible. What should they do next to migrate the database with minimal downtime?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS DMS to perform a full load and then enable ongoing replication
Option B is correct because AWS DMS can perform a full load and then continuously replicate changes to minimize downtime. Option A is wrong because copying the backup to S3 and restoring to RDS would require downtime during the restore. Option C is wrong because they already assessed compatibility with SCT. Option D is wrong because manual export/import requires downtime.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Export the database to flat files and upload to S3, then import into RDS
Why it's wrong here
This requires downtime.
✗
Use AWS SCT to convert the schema and then use AWS DMS
Why it's wrong here
SCT is already used; no conversion needed.
✓
Use AWS DMS to perform a full load and then enable ongoing replication
Why this is correct
DMS allows minimal downtime migration.
Related concept
Static NAT maps one inside address to one outside address.
✗
Take a full backup of the on-premises SQL Server, upload it to Amazon S3, and restore to RDS
Why it's wrong here
This requires downtime for backup and restore.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Use AWS DMS to perform a full load and then enable ongoing replication — Option B is correct because AWS DMS can perform a full load and then continuously replicate changes to minimize downtime. Option A is wrong because copying the backup to S3 and restoring to RDS would require downtime during the restore. Option C is wrong because they already assessed compatibility with SCT. Option D is wrong because manual export/import requires downtime.
