The correct answer is to apply a Kubernetes NetworkPolicy to deny all ingress and egress traffic to the compromised pod, execute commands inside the pod for forensics, and terminate the pod to stop the compromise. A NetworkPolicy acts as a software-defined firewall, immediately isolating the pod from lateral movement within the cluster, while kubectl exec allows you to capture volatile data like running processes or network connections before the pod is killed. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your ability to balance containment speed with forensic preservation—a common trap is choosing to delete the entire namespace, which would wipe evidence and disrupt other workloads, or scaling down the deployment, which is slower and may not stop a malicious process already running. Remember the incident response triad for EKS: isolate, investigate, terminate. For a memory tip, think “Net, Exec, Kill” as the three rapid-response actions that preserve both security and evidence.
DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company is designing an incident response strategy for its Amazon EKS cluster. Which THREE steps should be taken to ensure rapid response to a compromised pod?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Delete the pod using kubectl delete pod.
Option A is correct because a network policy can isolate the pod. Option B is correct because executing commands helps gather forensics. Option C is correct because terminating the pod stops the compromise. Option D is wrong because deleting the namespace would affect other resources. Option E is wrong because scaling down the deployment might not be immediate enough.
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.
✗
Delete the entire namespace to ensure all resources are removed.
Why it's wrong here
Deleting namespace is too aggressive and affects other workloads.
✗
Scale down the deployment to 0 replicas.
Why it's wrong here
Scaling down will also terminate the pod but might be slower than direct deletion.
✓
Delete the pod using kubectl delete pod.
Why this is correct
Terminating the pod stops the compromise.
Related concept
Static NAT maps one inside address to one outside address.
✓
Use kubectl exec to gather forensic data from the pod before termination.
Why this is correct
Forensic data may be lost after termination.
Related concept
Static NAT maps one inside address to one outside address.
✓
Apply a Kubernetes NetworkPolicy to deny all ingress/egress traffic to the compromised pod.
Why this is correct
Network isolation prevents lateral movement.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
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 DOP-C02 NAT questions on configuration and troubleshooting.
