Explanation: In a CloudBees CD/RO-based GitOps implementation, the "GitOps operator" is a built-in agent that continuously monitors the Git repository for changes. Whenever a change is detected in the Git repository, the GitOps operator triggers the necessary actions within CloudBees CD/RO to update the corresponding environments and ensure they match the desired state defined in the version-controlled configurations. This tight integration between the Git repository and the CloudBees CD/RO platform is a key enabler of the
GitOps approach, ensuring that the software delivery process remains in sync with the version-controlled definitions.

How can you ensure that the execution of parallel stages in a CloudBees CD/RO pipeline is fault-tolerant and resilient to failures?
1. Use the try-catch block to handle errors and failures in the overall parallel step
2. Implement custom error handling and retry logic within each parallel stage
3. Leverage the built-in failure handling mechanisms of the parallel step
4. There is no way to make the execution of parallel stages fault-tolerant in a CloudBees CD/RO pipeline
Answer: B
RO pipeline is fault-tolerant and resilient to failures, the recommende oach is to implement custom error handling and retry logic within eac lel stage. The parallel step itself does not have built-in mechanisms to matically handle stage failures, so you need to manage the fault tolera esilience at the individual stage level.
