SDLC Automation →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is to add a manual approval action in the CodePipeline pipeline before the production deployment stage, configured to require a designated approver. This is correct because CodePipeline natively supports a manual approval stage that pauses the pipeline and sends a notification to specified approvers, who must explicitly approve or reject the transition before the deployment proceeds to production. By placing this approval action in a dedicated stage just before the production deploy stage, you ensure that only the production environment requires human sign-off, while development and testing stages can remain fully automated. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of pipeline stage-level controls versus service-level approvals—a common trap is confusing CodeDeploy’s deployment groups (which lack approval workflows) with CodePipeline’s built-in approval action. Remember the memory tip: “Approve in the pipeline, not in the deploy” to avoid selecting CodeDeploy or SNS-based solutions.

DOP-C02 SDLC Automation Practice Question

This DOP-C02 practice question tests your understanding of sdlc automation. 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 startup is using AWS CodeCommit to store their application code. They have set up a CI/CD pipeline with AWS CodePipeline and AWS CodeBuild. The pipeline consists of a source stage from CodeCommit, a build stage using CodeBuild, and a deploy stage using AWS CodeDeploy to deploy to an Auto Scaling group of EC2 instances. Recently, a developer committed code that introduced a critical bug, and the pipeline automatically deployed the bug to production, causing an outage. The team wants to implement a manual approval step before production deployment. They also want to ensure that the approval step is only required for deployments to the production environment, not for development or testing. Which solution should they implement?

A
Add a manual approval action in the CodePipeline pipeline before the production deployment stage. Configure the approval to require a designated approver.
Manual approval actions in CodePipeline allow a human to approve before deployment.
B
Configure the CodeDeploy deployment group to require approval before deploying to any instance.
Why wrong: CodeDeploy does not have built-in manual approval.
C
Use Amazon Simple Notification Service (SNS) to send a notification to the team and have them manually stop the pipeline if needed.
Why wrong: This does not enforce a mandatory approval step.
D
Use Amazon CloudWatch Events to trigger an AWS Lambda function that sends an approval request via email and pauses the pipeline until approved.
Why wrong: This is overly complex and not a native feature.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Add a manual approval action in the CodePipeline pipeline before the production deployment stage. Configure the approval to require a designated approver.

Option A is correct because CodePipeline supports manual approval actions that can be added as a stage before production deployment. By configuring separate pipelines or stages for different environments, the approval step can be limited to production. Option B is wrong because CodeDeploy does not have approval workflows. Option C is wrong because CloudWatch Events does not provide manual approval. Option D is wrong because SNS is for notifications, not approvals.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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 DOP-C02 NAT questions on configuration and troubleshooting.
