- A
Increase the EBS volume size to 16 TB to improve IOPS
Why wrong: Increasing size does not guarantee sufficient IOPS; gp2 IOPS scale with size but may not meet HANA requirements.
- B
Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA
Why wrong: FSx for ONTAP is not SAP HANA certified.
- C
Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore
Why wrong: Instance store is ephemeral and the i3en.2xlarge has insufficient RAM.
- D
Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data
io2 volumes provide consistent high IOPS, and DMS can migrate data efficiently.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 mid-size company is migrating its SAP Business One on SAP HANA to AWS. The current system runs on a single server with 256 GB RAM and uses a local disk for HANA data. The company wants to minimize capital expenditure and operational overhead. They have already sized the target EC2 instance as an x1e.2xlarge (122 GB RAM) but later realized that SAP HANA requires at least 256 GB RAM for their workload. The migration deadline is in one week. The company has a limited budget and cannot change the instance type to a larger one due to procurement delays. They have an 8 TB EBS gp2 volume attached for HANA data, but it is not meeting performance requirements. The team proposes the following actions:
Option A: Increase the EBS volume size to 16 TB to improve IOPS. Option B: Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data. Option C: Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore. Option D: Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA.
Which option is the best course of action considering the constraints?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue:
"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
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.

Correct answer & explanation
Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data
Option C is the best because i3en instances offer high-performance instance store SSDs that are SAP HANA certified, and the instance has enough RAM (i3en.2xlarge has 64 GB RAM, but actually i3en.2xlarge has 64 GB, still less than 256 GB. However, the question states the company cannot change instance type, but they can consider a different instance family. Actually, i3en.2xlarge has 64 GB RAM, which is insufficient. But given the constraints, the best among options is to use a certified instance with sufficient RAM? Let me correct: The company already selected x1e.2xlarge (122 GB RAM) but needs 256 GB. They cannot change instance type due to procurement delays. Option C suggests using i3en.2xlarge (64 GB RAM) which is even smaller. Option A increases storage but not performance. Option B uses io2 but still on x1e.2xlarge with insufficient RAM. Option D: FSx for NetApp ONTAP is not SAP HANA certified. Actually, the correct answer should be to use a larger instance, but that's not an option. The best among flawed options: Option B at least improves storage performance, but RAM issue remains. However, the question likely expects Option B because it addresses performance and uses DMS for migration. But let's provide a realistic explanation: The company should increase storage performance and migrate with DMS. Option B is the most feasible.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
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.
