- A
The CloudWatch Logs agent configuration file does not specify the correct log file path or the log files do not exist.
Correct: If the path is wrong or files are missing, the agent will not send logs.
- B
The CloudWatch Logs agent does not have read permissions on the /var/log/app/ directory.
Why wrong: Incorrect: The agent runs as root, so permissions are not an issue.
- C
The .ebextensions configuration file is not executed because it is in the wrong directory.
Why wrong: Incorrect: .ebextensions files are processed by Elastic Beanstalk.
- D
The IAM instance profile does not have the necessary permissions to write to CloudWatch Logs.
Why wrong: Incorrect: This would prevent any logs from being sent, but the agent is running, so permissions are likely correct.
Fixing CloudWatch Logs Not Appearing from Elastic Beanstalk
This DVA-C02 practice question tests your understanding of development with aws services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: cloudWatch Logs agent configuration. 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 runs a Node.js application on AWS Elastic Beanstalk. The application writes log files to /var/log/app/. The operations team wants to stream these logs to Amazon CloudWatch Logs for monitoring and alerting. The developer configures the Elastic Beanstalk environment to include a .ebextensions configuration file that sets up the CloudWatch Logs agent. The configuration file specifies the log group and the log stream prefix. After deploying the updated environment, the logs are not appearing in CloudWatch Logs. The developer checks the EC2 instance and confirms that the CloudWatch Logs agent is running and the configuration file is present in /etc/awslogs/. What is the most likely reason the logs are not being sent?

Answer choices
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
The CloudWatch Logs agent configuration file does not specify the correct log file path or the log files do not exist.
The most likely reason logs are not appearing is that the CloudWatch Logs agent configuration file (usually at /etc/awslogs/awslogs.conf) does not specify the correct log file path or the log files do not exist. The agent runs as root, so permissions are typically not an issue. The .ebextensions configuration is valid and would be executed. While IAM permissions are necessary, the agent itself will not send logs if it cannot find the files to read, making incorrect path the primary suspect.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates often assume IAM permissions are the issue when logs are missing, but the agent must first be correctly configured to read the right files.

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
CloudWatch Logs agent configuration
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.
