SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company uses AWS CodePipeline to deploy a web application to an Elastic Beanstalk environment. The deployment pipeline includes a source stage, a build stage using CodeBuild, and a deploy stage. Recently, deployments have been failing in the deploy stage with the error: 'The environment is in an invalid state for this operation.' The developer confirms the build artifacts are correct. What is the MOST likely cause?
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
✓
Another deployment or configuration update is already in progress on the environment
If another deployment or configuration update is already in progress, Elastic Beanstalk prevents concurrent operations, resulting in the 'environment is in an invalid state for this operation' error. Option A is incorrect because load balancer unavailability would cause health check or routing issues, not this error. Option B is incorrect because insufficient Auto Scaling capacity would lead to scaling failures, not an invalid state error. Option C is incorrect because CodePipeline does not impose instance type restrictions on Elastic Beanstalk environments.
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 environment's load balancer is not available
Why it's wrong here
That would cause health check failures, not invalid state.
- ✗
The environment's Auto Scaling group has insufficient capacity
Why it's wrong here
This would cause scaling issues, not an invalid state error.
- ✗
The Elastic Beanstalk environment uses a t2.micro instance type which is not supported by CodePipeline
Why it's wrong here
t2.micro is supported.
- ✓
Another deployment or configuration update is already in progress on the environment
