QuestionQ1

Deployment and Release Management

How should a DevOps engineer carry out an AEM upgrade while preserving version history and workflows?

Explanation

An in-place upgrade preserves the existing AEM repository, including its version history and workflow data. The supported procedure is to replace the Quickstart JAR outside the existing crx-quickstart directory, unpack the upgraded JAR, and start the instance so the repository is upgraded in place.

QuestionQ2

Deployment and Release Management

A DevOps engineer must deploy a branch to the Stage Environment so that UAT testing can start. The engineer initiates a Production Pipeline using a manual trigger.

The Code Scanning results provide this summary:

  • Security Rating: A -
  • Reliability Rating: A -
  • Maintainability Rating: A -
  • Code Coverage: 10%

Summary: Partial Pass -

Which two actions should the DevOps engineer take?

Choose two
Explanation

In Adobe Experience Manager Cloud Manager pipelines, code quality gating differentiates between critical failures, which halt the pipeline outright, and important (non-critical) threshold failures — such as insufficient Code Coverage — which produce a Partial Pass that pauses the pipeline for a manual decision rather than blocking it permanently. An authorized DevOps engineer can override this build step to allow the Stage deployment to proceed so UAT testing is not delayed, while in parallel the Code Coverage shortfall should be flagged back to the development team so the underlying test-coverage gap is addressed before the next release, rather than leaving code quality debt unaddressed. This combination — override to unblock the immediate deployment and route the coverage issue to the developer — directly matches how the quality-gate override mechanism is intended to be used.

QuestionQ3

Deployment and Release Management

A customer is using the Content Transfer Tool (CTT) to migrate to AEM as a Cloud Service. Only published content must be migrated to the target Production instance.

Which two actions should the DevOps engineer perform?

Choose two
Explanation

Content extracted from the source Publish instance represents the published content set. CTT can ingest that migration set into a target Author instance. After ingestion, a copied Publish Content Tree workflow on the target Author instance publishes the migrated content to the target Publish tier, so the Production environment receives only the source content that had been published.

QuestionQ4

Security, Access, and Permissions

A corporate AEM as a Cloud Service customer is preparing to launch a new website feature. The feature relies on an internal Java API available in the IT-managed artifact repository. Repository access is protected by Basic Authentication.

The DevOps engineer must make this dependency available to Cloud Manager.

What should the DevOps engineer do?

Explanation

Cloud Manager can retrieve artifacts from a password-protected Maven repository when the repository credentials are stored as secret pipeline variables and referenced from .cloudmanager/maven/settings.xml in the Git repository. The Adobe I/O CLI command aio cloudmanager:set-pipeline-variables configures those pipeline variables.

QuestionQ5

Performance Optimization and Troubleshooting

A DevOps engineer configures the statfile at level 2 in the Dispatcher configuration. The document root is set to /var/www.

Which level is protected from invalidation?

Explanation

With Dispatcher /statfileslevel set to 2, level-2 folders beneath the document root establish separate invalidation subtrees. /content/dam is a level-2 subtree and is therefore not invalidated by changes in a different level-2 subtree, such as /content/eu.
