The answer is network bandwidth available for data transfer and SAP HANA version compatibility. Network bandwidth is critical because backup and restore migration involves transferring large database volumes over the network, and insufficient bandwidth can extend the migration window beyond acceptable limits, making it a primary bottleneck. Version compatibility ensures that the HANA backup taken from the source system can be successfully restored on the target AWS instance, as incompatible versions will cause restore failures. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of offline migration constraints versus online replication; a common trap is confusing latency with bandwidth, but latency matters for real-time replication, not for bulk backup transfer. Remember the mnemonic “Bandwidth and Build” — bandwidth for the pipe, build for the version match.
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.
Which TWO considerations are critical when migrating an SAP HANA database to AWS using backup and restore? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Compatibility of SAP HANA version between source and target
Network bandwidth directly impacts transfer time, and the correct HANA version compatibility ensures the backup can be restored. Option A is irrelevant because latency is not a major factor for offline backup transfer. Option C is wrong because EBS encryption is optional. Option E is wrong because SAP HANA does not run on RDS.
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.
✓
Compatibility of SAP HANA version between source and target
Why this is correct
The target HANA version must support restoring backups from the source version.
Related concept
Static NAT maps one inside address to one outside address.
✓
Network bandwidth available for data transfer
Why this is correct
Bandwidth determines the speed of backup file transfer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon RDS for SAP HANA instance class
Why it's wrong here
SAP HANA is not available on Amazon RDS; it runs on EC2.
✗
Encryption settings for Amazon EBS volumes
Why it's wrong here
EBS encryption is optional and not a critical migration consideration.
✗
Network latency between on-premises and AWS
Why it's wrong here
Latency is less critical for offline backup transfer than bandwidth.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
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.
Migration — This question tests Migration — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Compatibility of SAP HANA version between source and target — Network bandwidth directly impacts transfer time, and the correct HANA version compatibility ensures the backup can be restored. Option A is irrelevant because latency is not a major factor for offline backup transfer. Option C is wrong because EBS encryption is optional. Option E is wrong because SAP HANA does not run on RDS.

What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
