Adobe Experience Manager DevOps Engineer Expert Sample Questions:

1. A customer's Sandbox environment is hibernated, and the customer wants it to stay in that state until they are ready for testing. While hibernated, the customer wants custom code deployed, and they should have the new code once the environment is de-hibernated.
What should the DevOps engineer do?

A) Use Cloud Manager to de-hibernate the environment and then deploy the code
B) Use a pipeline to deploy custom code to the hibernated environment
C) Create a hibernate branch in Git and perform an update from this branch
D) Use Developer Console to de-hibernate the environment and then deploy the code

2. The Non-Production Deployment Pipeline for an Adobe Experience Manager as a Cloud Service program terminates prematurely.
Upon initial investigation, the DevOps engineer notes the following:
The pipeline status is ERROR
The last pipeline step is Build Images
The previous execution of the pipeline completed successfully
The DevOps engineer scans the log file, which produces the following output:
INFO [Apache Sling Repository Startup Thread #1] org.apache.sling.jcr.repoinit.impl.GroupMembershipVisitor Adding members '[corp-comm-authors]' to group 'contributor' ERROR [Apache Sling Repository Startup Thread #1] com.adobe.granite.repository.impl.SlingRepositoryManager Exception in a SlingRepositoryInitializer, SlingRepository service registration aborted java.lang.RuntimeException: contributor is not a group com.google.javascript.jscomp.LoggerErrorManager println SEVERE: /libs/cq/gui/components/workflow/editor/clientlibs/workflow.js:8033: ERROR - This language feature is only supported for ECMASCRIPT6 mode or better: const declaration.

To avoid affecting other tasks, processing was stopped.
Which two steps should the DevOps engineer take next? (Choose two.)

A) Inspect the most recent git commits in the pipeline branch for changes to repoinit configs.
B) Manually trigger the pipeline to see if it terminates at the same step with similar log output.
C) Temporarily switch the Non-Production pipeline from the development branch to the stable branch and rebuild to restore functionality in the environment.
D) File a ticket named "SEVERE ECMASCRIPT ERROR" in the project issue tracker and assign it to a Frontend Developer for further investigation.
E) Add an oak:index definition for the sling:vanityPath property.

3. During the Non-Production pipeline, an issue occurs with a Security Rating of B.
Based on the Review Results, all critical and mandatory tests passed.
What should the DevOps engineer do to proceed with the build?

A) Reconfigure the pipeline to pull from another branch.
B) Bypass testing for security and proceed to performance.
C) Reject the deployment and restart it again.
D) Switch on Override failed results and submit.

4. A DevOps engineer is working on an on-premise AEM 6.5 setup on a virtual private cloud (VPC). The DevOps engineer needs to automate the creation of additional publish instances based on increased load to the current architecture. Events based on triggers are set up to monitor the load on the load balancer. When the threshold is reached, an automated script is required to add the publish instance to the architecture.
Which steps should the automated script perform?

A) Set up a replication agent on the load balancer
B) Take one of the publishers out of the load balancer and stop the virtual machine Clone the stopped virtual machine containing the publish instance and Dispatcher Start up the two publish instance and check for ready states Add a replication agent and configure it to point to the new publish instance Add the new publish instance to the load balancer
C) Add a replication agent to author
Clone an existing AEM publish instance with a Dispatcher to a new virtual machine Configure the replication agent to point to the new publish instance Check the health of the new publish instance and Dispatcher Add the publish instance and Dispatcher pair to the load balancer
D) Install AEM 6.5 on a new virtual machine
Add a replication agent and configure it to point to the new publish instance Tree activate the pages from author to the new publish instance Attach a Dispatcher Add the publish instance and Dispatcher pair to the load balancer

5. 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) Review the performance tests retrieved from the Cloud Manager pipeline.
B) Check the Code Quality gate for bad queries from the Cloud Manager pipeline.
C) Investigate query performance via Cloud Manager Developer Console.
