AWS DevOps CI/CD Pipelines 5

Question 1

A pipeline must build artifacts and then deploy them to multiple AWS regions simultaneously. Which CodePipeline feature supports cross-region actions?

Accepted Answer

Multi-Region Action Groups using cross-region artifact stores

Answer

CodePipeline supports cross-region actions by configuring region-specific artifact stores; actions in a stage can target different regions simultaneously.

Question 2

When using AWS CodeBuild with a cache configuration, which cache type stores cached files in an Amazon S3 bucket between builds?

Accepted Answer

S3 cache

Answer

The S3 cache type in CodeBuild uploads and downloads cached directories (like dependency folders) to/from a specified S3 bucket across builds.

Question 3

A development team wants to use feature flags to decouple code deployment from feature release in their CI/CD pipeline. Which AWS service directly supports this pattern?

Accepted Answer

AWS AppConfig

Answer

AWS AppConfig allows teams to deploy feature flags and configuration changes independently of code deployments, enabling safe progressive feature releases.

Question 4

In CodePipeline, what happens when two pipeline executions are triggered in quick succession and the pipeline is already running?

Accepted Answer

The second execution is queued and supersedes the first in pending stages once earlier stages complete

Answer

CodePipeline queues the newer execution; if the older one is still running when the newer one catches up, the newer one supersedes (replaces) it in pending stages.

Question 5

Which AWS CodeBuild feature allows you to run multiple build tasks in parallel within a single build project using the same buildspec?

Accepted Answer

Build batching with batch build configuration

Answer

CodeBuild batch builds allow a single buildspec to define multiple build tasks that run in parallel or in a dependency graph within a single batch execution.
