This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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
Refer to the exhibit. An SAP administrator is reviewing the block device mappings of an EC2 instance. What is the impact of the DeleteOnTermination setting on /dev/sdf?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The volume will persist after the instance is terminated
Option B is correct because DeleteOnTermination is false for /dev/sdf, meaning the volume will persist after the instance is terminated. Option A is incorrect because the volume will not be deleted. Option C is incorrect because the volume is attached, not a snapshot. Option D is incorrect because the volume will not be automatically deleted.
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 volume will persist after the instance is terminated
Why this is correct
The volume will remain and can be attached to another instance.
Related concept
Static NAT maps one inside address to one outside address.
✗
The volume will be automatically deleted after 30 days
Why it's wrong here
No automatic deletion occurs; it persists until manually deleted.
✗
The volume will be deleted when the instance is terminated
Why it's wrong here
DeleteOnTermination is false, so it will not be deleted.
✗
The volume is a snapshot of the root volume
Why it's wrong here
The volume is an EBS volume, not a snapshot.
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.
Technology — This question tests Technology — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: The volume will persist after the instance is terminated — Option B is correct because DeleteOnTermination is false for /dev/sdf, meaning the volume will persist after the instance is terminated. Option A is incorrect because the volume will not be deleted. Option C is incorrect because the volume is attached, not a snapshot. Option D is incorrect because the volume will not be automatically deleted.
What should I do if I get this PAS-C01 question wrong?
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 key concept behind this question?
Static NAT maps one inside address to one outside address.
