The correct answer is to use an SAP-certified backup/restore tool, such as Commvault, to restore the MSSQL database directly to Amazon EC2. This approach meets the strict 4-hour downtime requirement because backup/restore tools are optimized for large database transfers, leveraging compression and parallel streaming to move a 500 GB database quickly, whereas SAP SWPM export/import would take significantly longer due to its sequential processing. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to distinguish between database-specific migration tools and generic server replication methods; a common trap is choosing AWS DMS, which lacks full support for SAP-specific schemas, or CloudEndure, which is designed for server-level replication rather than database-optimized transfer. Remember that when migrating SAP ERP with MSSQL under tight downtime, always prioritize SAP-certified backup/restore tools over export/import or DMS. Memory tip: “Backup/restore beats export/import for speed—think B.R.E.A.D. (Backup Restore, Efficient, AWS, Direct).”
PAS-C01 Migration Practice Question
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 migrating an SAP ERP system to AWS. The SAP application runs on a Windows Server with an MSSQL database. The migration must be completed within a strict 4-hour downtime window. The current database is 500 GB. Which migration strategy should be used to meet the downtime requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL
Using SAP HANA System Replication is not applicable because the source is MSSQL. Option A is incorrect because SAP SWPM export/import is time-consuming and may exceed 4 hours. Option B is incorrect because AWS DMS may not fully support SAP-specific schemas and could have compatibility issues. Option D is incorrect because AWS CloudEndure Migration is for server migration, not database-specific optimized transfer.
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.
✗
Use SAP SWPM export/import to migrate the database
Why it's wrong here
Export/import for MSSQL can take longer than 4 hours for 500 GB.
✓
Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL
Why this is correct
Backup/restore can be faster and is supported for MSSQL on EC2.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use AWS DMS with ongoing replication, then cutover
Why it's wrong here
DMS may not fully support SAP-specific objects and could require schema conversion.
✗
Use AWS CloudEndure Migration to replicate the entire server
Why it's wrong here
CloudEndure replicates at block level but adds overhead; database consistency may be an issue.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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.
