DVA-C02 Deployment Practice Question

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 build environment does not have enough memory.

  Why it's wrong here

  Insufficient memory in an AWS CodeBuild environment typically manifests as an OutOfMemoryError during the build process itself, particularly when compiling large projects or running memory-intensive tests. This error would occur *after* the build environment successfully provisions and attempts to execute build commands within the Docker container. A "pull image" error, however, indicates a failure at an earlier stage, specifically when CodeBuild tries to download the specified Docker image to even *start* the build environment, making memory capacity irrelevant at that point.

• ✓

  The Docker image specified in the build environment does not exist or the repository is not accessible.

  Why this is correct

  A "pull image" error in AWS CodeBuild directly signifies that the CodeBuild service was unable to retrieve the specified Docker image from its source repository. This can occur if the image name or tag is incorrect, leading to the image not being found, or if CodeBuild lacks the necessary IAM permissions to access a private repository like Amazon ECR. Network connectivity issues to the repository or misconfigured repository policies could also prevent a successful image pull, halting the build before any commands execute.

• ✗

  The build command has a syntax error.

  Why it's wrong here

  A syntax error within a build command defined in the `buildspec.yml` file would result in a build failure during the `BUILD` phase, specifically when the shell attempts to execute the malformed command. The error message would typically indicate a parsing issue or an unrecognized command, such as `command not found` or `syntax error near unexpected token`. This type of error occurs *after* the Docker image has been successfully pulled and the build environment initialized, which is distinct from an initial image pull failure.

• ✗

  The buildspec.yml file does not define artifacts.

  Why it's wrong here

  If the `buildspec.yml` file does not define any artifacts, or if the specified artifact paths do not exist at the end of the build, CodeBuild would complete the build process but might report a warning or an error related to artifact upload. The build itself would likely succeed in terms of command execution, but the output artifacts would be missing or incomplete. This issue occurs at the very end of the build lifecycle, long after the initial Docker image pull, and would not prevent the build environment from even starting.
