DOP-C02 Monitoring and Logging Practice Question

This DOP-C02 practice question tests your understanding of monitoring and logging. 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.

Drag and drop the steps to set up an AWS CodeBuild project to build a Docker image and push it to Amazon ECR.

A
Create ECR repository, then Write buildspec.yml, then Create CodeBuild project with privileged mode, then Start build
This is correct because you need the ECR repository first to store the image, then write the buildspec, then create the project with privileged mode to allow Docker, then start the build.
B
Create CodeBuild project, then Create ECR repository, then Write buildspec.yml, then Start build
Why wrong: This is incorrect because you must create the ECR repository before the build project, as the build will push to the repository. Also, writing buildspec after project creation may cause missing file errors.
C
Write buildspec.yml, then Create ECR repository, then Create CodeBuild project without privileged mode, then Start build
Why wrong: This is incorrect because the CodeBuild project must have privileged mode enabled to run Docker commands; without it, Docker cannot be used. Also, the ECR repository should be created before the build.
D
Create ECR repository, then Start build, then Create CodeBuild project, then Write buildspec.yml
Why wrong: This is incorrect because you cannot start a build before creating the CodeBuild project. The buildspec must be written before the project can reference it, and the project must exist before triggering a build.

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

✓

Create ECR repository, then Write buildspec.yml, then Create CodeBuild project with privileged mode, then Start build

The correct order to set up an AWS CodeBuild project for building a Docker image and pushing to Amazon ECR is: first create the ECR repository, then write the buildspec.yml file, then create the CodeBuild project with privileged mode enabled, and finally start the build. This sequence ensures the repository exists, the build specification is ready, and the project has the necessary permissions to build and push the Docker image.

Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

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 ECR repository, then Write buildspec.yml, then Create CodeBuild project with privileged mode, then Start build
Why this is correct
This is correct because you need the ECR repository first to store the image, then write the buildspec, then create the project with privileged mode to allow Docker, then start the build.
Related concept
Authentication checks who the user is.
✗
Create CodeBuild project, then Create ECR repository, then Write buildspec.yml, then Start build
Why it's wrong here
This is incorrect because you must create the ECR repository before the build project, as the build will push to the repository. Also, writing buildspec after project creation may cause missing file errors.
✗
Write buildspec.yml, then Create ECR repository, then Create CodeBuild project without privileged mode, then Start build
Why it's wrong here
This is incorrect because the CodeBuild project must have privileged mode enabled to run Docker commands; without it, Docker cannot be used. Also, the ECR repository should be created before the build.
✗
Create ECR repository, then Start build, then Create CodeBuild project, then Write buildspec.yml
Why it's wrong here
This is incorrect because you cannot start a build before creating the CodeBuild project. The buildspec must be written before the project can reference it, and the project must exist before triggering a build.

Common exam traps

Common exam trap: authentication is not authorization

Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.

Trap categories for this question

Command / output trap
This is incorrect because the CodeBuild project must have privileged mode enabled to run Docker commands; without it, Docker cannot be used. Also, the ECR repository should be created before the build.

Detailed technical explanation

How to think about this question

This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.

KKey Concepts to Remember

Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.

TExam Day Tips

Do not assume successful login means full administrative access.
Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
Separate login problems from permission problems before choosing the answer.

Key takeaway

Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Real-world example

How this comes up in practice

A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

What to study next

Got this wrong? Here's your next step.

Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related DOP-C02 questions on access control and AAA configuration.
