AZ-400 Continuous Delivery & Release Management 3

Question 1

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

Accepted Answer

Rolling

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 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?

Accepted Answer

CD trigger on the ACR artifact

Answer

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

Question 4

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

Accepted Answer

Queue-time variables

Answer

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

Question 5

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

Accepted Answer

Pipeline chaining via build completion trigger

Answer

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