SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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.
A SysOps administrator suspects that an Amazon Linux 2 EC2 instance has been compromised. The instance is part of an Auto Scaling group and is currently running. The administrator needs to preserve the root volume for forensic analysis while minimizing the impact to the application. Which action should the administrator take FIRST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Detach the root volume from the instance and create a snapshot of the volume for analysis.
Detaching the root volume and creating a snapshot preserves the evidence while the instance can be terminated and replaced by the Auto Scaling group. Option A (terminate) loses the volume. Option C (stop) leaves the volume attached to a stopped instance. Option D (AMI) creates a new image but does not preserve the exact state if the instance continues running.
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.
✗
Create an Amazon Machine Image (AMI) of the instance while it is running.
Why it's wrong here
Creating an AMI does not preserve the exact state of the root volume for forensic analysis.
✗
Stop the instance and create an Amazon EBS snapshot of the root volume.
Why it's wrong here
Stopping the instance leaves the volume attached; detaching first is more secure for forensic isolation.
✓
Detach the root volume from the instance and create a snapshot of the volume for analysis.
Why this is correct
Detaching preserves the volume and allows forensic snapshot; Auto Scaling will launch a replacement instance.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Terminate the instance immediately to stop any malicious activity.
Why it's wrong here
Termination destroys the root volume, losing forensic evidence.
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 SOA-C02 NAT questions on configuration and troubleshooting.
Monitoring, Logging, and Remediation — This question tests Monitoring, Logging, and Remediation — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Detach the root volume from the instance and create a snapshot of the volume for analysis. — Detaching the root volume and creating a snapshot preserves the evidence while the instance can be terminated and replaced by the Auto Scaling group. Option A (terminate) loses the volume. Option C (stop) leaves the volume attached to a stopped instance. Option D (AMI) creates a new image but does not preserve the exact state if the instance continues running.
What should I do if I get this SOA-C02 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 SOA-C02 NAT questions on configuration and troubleshooting.
Are there clue words in this question I should notice?
Yes — watch for: "first". Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
