The correct answer is that the data volume (/dev/sdf) will persist after instance termination because its DeleteOnTermination attribute is set to false. This attribute controls whether an Amazon EBS volume is automatically deleted when the attached EC2 instance is terminated; when set to false, the volume survives termination and retains its data, which is critical for SAP HANA database servers where preserving the data volume is essential. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this concept tests your understanding of EBS volume persistence and the DeleteOnTermination flag, often appearing in scenarios where an administrator must ensure data durability across instance lifecycles. A common trap is assuming all volumes are deleted by default, but only the root volume (typically /dev/xvda) has DeleteOnTermination set to true by default, while additional data volumes like /dev/sdf can be explicitly configured to persist. Remember the memory tip: “Root is removed, data is saved” — check the flag on non-root volumes to confirm persistence.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Network Topology
An SAP administrator executed the AWS CLI command shown in the exhibit. The EC2 instance i-0abcd1234efgh5678 is a SAP HANA database server. Which statement about the storage configuration is correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The data volume (/dev/sdf) will persist after instance termination.
Option B is correct: /dev/sdf has DeleteOnTermination set to false, meaning it will not be deleted when the instance is terminated, preserving the data. Option A is incorrect because /dev/xvda will be deleted. Option C is incorrect because the command only shows block device mappings, not root device type. Option D is incorrect because /dev/sdf is an EBS volume, not instance store.
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.
✗
The root volume (/dev/xvda) will persist after instance termination.
Why it's wrong here
A is wrong: DeleteOnTermination is true, so it will be deleted.
✗
The volume /dev/sdf is an instance store volume.
Why it's wrong here
D is wrong: it is an EBS volume.
✓
The data volume (/dev/sdf) will persist after instance termination.
Why this is correct
B is correct: DeleteOnTermination is false, so it persists.
Related concept
Static NAT maps one inside address to one outside address.
✗
The instance is booting from an instance store volume.
Why it's wrong here
C is wrong: the command shows EBS volumes.
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.

Command / output trap
C is wrong: the command shows EBS volumes.
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.

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.
