4. A DevOps engineer is monitoring an Adobe Managed Services AEM Sites environment. AEM Sites is being run for the customer. During the performance tests conducted via Cloud Manager, the DevOps engineer notices high CPU utilization.

What should the DevOps engineer do?

5. After deploying a new version of an AEM site, users report slow page load times.

What should be checked first?

Dispatcher cache settings and invalidation rules

OSGi component logs for errors

The number of active workflows running in AEM

CRX repository size and index settings

6. A DevOps engineer generates two content packages (/content/my-site): one from Author and one from Publish server, respectfully. Both packages have the same content structure. The developer notices the Publish package is larger than the Author package.

8. Developers add a content package module named "ui.utils" to the Maven project. The module provides debugging servlets for use in testing features for a website hosted on AEM as a Cloud Service. These servlets are not secured and should not be deployed to the production Cloud Service environment.

What should the DevOps engineer add?

Add "<dependency>" element identifying the "ui.utils" artifact and a matching "<embedded>" element to the "all" package pom.xml with a target path of /apps/mysite-packages/application/install.

Add a "<profile>" element in the "ui.utils" pom.xml that adds the "<cloudManagerTarget>all</cloudManagerTarget>" to the ui.utils package properties, which is activated when an env variable is set to a particular value.

Add a pipeline to the team's CI service that builds the ui.utils content package and uploads it to the Author server's CRX Package Manager servlet after receiving a successful response from a Cloud Manager webhook.

Deploy the "ui.utils" package using the CRX Package Manager directly in production.
