Read the first 7 Continuous Delivery & Release Management flashcards as text

  1. Which strategy in Azure Pipelines deployments replaces instances in batches rather than all at once or one at a time?

    Answer: Rolling

    The rolling strategy updates a subset of instances at a time, reducing downtime while gradually replacing the old version across all targets.

  2. What is the primary benefit of using environment approvals in Azure Pipelines YAML over classic release approvals?

    Answer: They integrate natively with YAML pipelines and can be reused across multiple pipelines

    Environment approvals in YAML pipelines are defined on the environment resource, making them reusable across any pipeline that targets that environment.

  3. A team uses Azure Container Registry (ACR) as a release artifact source. Which trigger type should they configure to start a release when a new image is pushed?

    Answer: CD trigger on the ACR artifact

    Configuring a continuous deployment (CD) trigger on the ACR artifact source automatically creates a new release when a matching container image is pushed.

  4. In Azure Pipelines, which variable scope takes the highest precedence when the same variable is defined at multiple levels?

    Answer: Queue-time variables

    Queue-time (run-time) variables set when manually triggering a pipeline override all other variable scopes including stage and job definitions.

  5. Which Azure Pipelines feature allows a single pipeline to produce artifacts consumed by a downstream release pipeline automatically?

    Answer: Pipeline chaining via build completion trigger

    Build completion triggers let a release pipeline start automatically when an upstream CI pipeline produces new artifacts, chaining CI and CD pipelines together.

  6. What does the 'maxParallel' property control in a rolling deployment strategy within Azure Pipelines?

    Answer: The number of deployment targets updated concurrently per rolling batch

    maxParallel in a rolling strategy defines how many targets in the deployment group receive the update simultaneously in each batch.

  7. Which Azure DevOps feature provides a centralized view of all deployments across environments, including their current version and health status?

    Answer: Environments hub in Azure Pipelines

    The Environments hub in Azure Pipelines shows deployment history, resource health, and currently deployed versions across all tracked environments.
