The correct answer is that the root volume will persist after instance termination and can be attached to another instance. This behavior is governed by the EBS DeleteOnTermination attribute; when set to false, the root volume is not deleted upon instance termination, ensuring the data remains intact and reusable. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this concept tests your understanding of EBS lifecycle management and how to architect for instance failure recovery without data loss. A common trap is assuming that root volumes are always deleted by default—while true for most instance types, explicitly setting DeleteOnTermination=false decouples the volume’s lifecycle from the instance’s. Remember, snapshots are independent of this setting, so relying solely on snapshots for persistence is unnecessary when the volume itself persists. Memory tip: “False keeps the data alive—attach, don’t delete.”
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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.
Network Topology
A company is migrating a critical database server to Amazon EC2. The root volume (EBS) is configured with DeleteOnTermination=false. After migration, the company needs to ensure that if the EC2 instance fails, a new instance can be quickly launched using the same data. The company takes regular snapshots of the volume. Which statement is correct regarding the root volume's behavior?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The root volume will persist after instance termination and can be attached to another instance.
Option B is correct because with DeleteOnTermination=false, the root volume persists after instance termination. Option A is wrong because the volume persists. Option C is wrong because the snapshot schedule is independent of the DeleteOnTermination setting. Option D is wrong because the root volume can be reused by creating a new instance and attaching it.
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 cannot be used as a boot volume for a new instance.
Why it's wrong here
The root volume can be used as a boot volume for a new instance if attached as /dev/sda1.
✗
The root volume will be automatically deleted when the instance is terminated.
Why it's wrong here
DeleteOnTermination=false means the volume persists.
✓
The root volume will persist after instance termination and can be attached to another instance.
Why this is correct
The volume remains and can be attached to a new instance for recovery.
Related concept
Static NAT maps one inside address to one outside address.
✗
Snapshots of the volume will be automatically deleted when the instance is terminated.
Why it's wrong here
Snapshots are independent and are not deleted when the instance terminates.
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 SAP-C02 NAT questions on configuration and troubleshooting.
