This solution will meet the requirements in the most operationally efficient manner because it will use CloudWatch Logs destination to aggregate the log groups from all the accounts to a single S3 bucket in the logging account. However, unlike option A, this solution will create a CloudWatch Logs destination for each region, instead of a single destination for all regions. This will improve the performance and reliability of the log delivery, as it will avoid cross-region data transfer and latency issues. Moreover, this solution will use an Amazon Kinesis data stream and an Amazon Kinesis Data Firehose delivery stream for each region, instead of a single stream for all regions. This will also improve the scalability and throughput of the log delivery, as it will avoid bottlenecks and throttling issues that may occur with a single stream.

To allow only creation/configuration of service-linked roles , you need a way to tightly scope what IAM actions the developer can perform. The most AWS-appropriate mechanism for “delegate limited IAM admin” is a role with a permissions boundary :

A permissions boundary sets the maximum permissions the role (and any roles it creates, depending on design) can ever have. This is a standard pattern to safely delegate IAM tasks without granting broad IAM administration.

You can define the role’s policy + boundary so the developer can call only the APIs required for service-linked roles (for example actions like creating service-linked roles and passing only allowed AWS service principals), while preventing general role/policy creation outside that scope.

Why the others don’t meet “service-linked roles only”:

A is vague (“common services”) and cross-account access doesn’t inherently restrict to only service-linked roles. It’s also more operational overhead than needed for a single dev account use case.

B PowerUserAccess is far too broad and does not restrict to service-linked roles.

C An SCP with Deny iam:* would block IAM entirely (including what the developer needs). Even if refined, SCPs set account-wide guardrails and are not the right tool to grant a single developer the precise ability to create only service-linked roles.

Deployment of config.txt file based on the appspec.yml:

The appspec.yml file specifies that config/config.txt should be copied to /usr/local/src/config.txt.

The source: / directive in the appspec.yml indicates that the entire directory structure starting from the root of the application source should be copied to the specified destination, which is /var/www/html.

Result of the Deployment:

The config.txt file will be specifically deployed to /usr/local/src/config.txt as per the explicit file mapping.

The entire directory structure including application/web will be copied to /var/www/html, but this does not include config/config.txt since it has a specific destination defined.

Thus, the config.txt file will be deployed only to /usr/local/src/config.txt.

Therefore, the correct answer is:

C. The config.txt file will be deployed to only /usr/local/src/config.txt.
