Which two actions should the DevOps engineer take? (Choose two.)

A DevOps engineer is configuring the statfile to level 2 in the dispatcher configuration. The document root is configured to /var/www.
Which level will be protected from invalidation?

A DevOps engineer must analyze a performance issue on AEM as a Cloud Service. A page is running slowly and takes a long time to render. A query seems to be the cause.
What should the DevOps engineer do to analyze this issue?

A customer reports that publish instances are experiencing high CPU utilization.
What diagnostic data must the DevOps engineer collect?

A DevOps engineer is managing an AEM as a Cloud Service Sites environment for a customer. After development tested the Maven build locally, a new development pipeline is executed. The development pipeline fails in the build steps with the following errors:

What should the DevOps engineer do?

A DevOps engineer is supporting a client on Adobe Managed Services. The setup will be migrated to AEM as a Cloud Service.
Which two methods can be applied for scaling publish instances on the current platform? (Choose two.)

A DevOps engineer receives reports from two content authors that they are unable to activate pages via the Touch UI on a production AEM author instance. The authors need to publish their updates within 24 hours to correspond with a product launch scheduled by the business.
After inspecting the server's error log, the DevOps engineer is unable to identify the cause of the issue, and creates a Support Case via the Admin Console.
Which priority level should be assigned for this Support Case?

A DevOps engineer needs to set up a service-oriented integration with Adobe Target in Adobe I/O CLI.
Which authentication method should be used?

A DevOps engineer is onboarding new members onto Cloud Manager. One new team member, a developer who is granted the Developer role, logs in successfully. The new team member cannot trigger a Build on the non-production pipeline because the build button does not display. The new team member checks their role in the profile using the User Roles section and confirms that the Developer role is assigned.
How can this issue be resolved?

A DevOps engineer needs to store a separate API key per author and publish instance servers. The API key needs to be available to the service class com.my_company.core.APIService.

API Keys -

Author: KEY-001 -

Publish: KEY-002 -
Which option should the DevOps engineer use?

An AEM instance is updating and replicating pages at a very high rate. Monitoring alerts indicate a high number of requests to the publish instances.
How can the DevOps engineer throttle the number of cache invalidations?

A developer informs a DevOps engineer that a page they are working on renders as expected in the AEM Authoring environment but appears blank when viewed through the dispatchers.
No errors are present in the browser console.
Other instances of this page template render properly.
The page renders properly when accessing with the www URL but renders blank with the non-www URL.
What is causing this issue?

A DevOps engineer notices that a system occasionally gets slower.
No deployment has been recently performed.
After a restart of the instance, the performance degradation is mitigated.
If no action is taken, the JVM tends to crash in an unpredictable manner with Out Of Memory exceptions.
There is no clear correlation between visitor peaks and crashes of the instances.
The same symptoms affect author and publish instances.
What is causing this issue?

A customer of multiple Adobe Experience Cloud products, including Analytics, Tags, and AEM as a Cloud Service, recently onboarded a new team for their Technical Documentation site. This team is separate from the team that manages the Marketing site. The Marketing team was the first group to start using AEM, and they originally named their Admin Console group, "AEM Authors".
To enable independent permissions management for both teams, the Admin Console Administrator renames the "AEM Authors" group to "Marketing AEM Authors", and adds a separate group for the Technical Documentation authors.
The DevOps engineer receives a report from the Marketing team that a new team member is unable to access the Production environment after being added to the "Marketing AEM Authors" group in Admin Console.
What should the DevOps engineer do?

The project builds and deploys successfully on a local environment. A DevOps engineer deploys the same project source code on an AEM as a Cloud Service Non-Production pipeline. The pipeline fails at the Build & Unit Testing stage.
The end of the build_maven_build.log shows the following log messages:

The non-production pipeline was run once more, and the build failed at the same step with the same errors in the build log file.
How should the DevOps engineer resolve this issue?

The development team asks the DevOps engineer for help to set up Java remote debugging on a local AEM instance to debug an AEM application. The DevOps engineer needs to activate remote debugging on port 8000.
Which JVM parameter should the DevOps engineer add to perform this task?

A DevOps engineer notices that the Online Revision Garbage collection is not running as part of the daily maintenance tasks.
After inspecting the server's error log, the following shows up during the maintenance schedule:
"Revision GC will not run: Size delta is N% or N/N (N/N bytes), so skipping compaction for now"
The DevOps engineer needs to make sure that the revision garbage collection runs during the scheduled maintenance task.
Which additional step should the DevOps engineer take?
