Question1: After which maintenance processes can a datastore garbage collection achieve the most regain of disk space?

Question2: A DevOps Engineer notices that the disk usage for an AEM author instance is constantly going up.
Upon further investigation, it is revealed:
- Online Compaction is unable to complete revision cleanup task during the daily maintenance window
- Segment Store Size has gone up from 8 GB to 13 GB
- The following message is logged in the error.log file
Canceling RevisionGC. The task was either stopped by the user or the Maintenance Window reached its end - Lucene Binaries Cleanup task completed successfully during the daily maintenance window What additional step can be performed during the weekly maintenance window to reduce the overall disk usage?

Question3: A DevOps Engineer notices that existing pages are not updated through a package installation. The updated pages are present after deleting the pages that are not updating, and reinstall the package.
What is the source of the problem?

Question4: A DevOps Engineer is configuring a non production deployment pipeline. The code quality is checked in the pipeline. A security check is configured in the deployment pipeline to identify any major security issues before a production deployment.
Which other check should be executed before deployment to production?

Question5: A DevOps Engineer finds that customers are experiencing long response times.
* It is unclear which responses are slow.
* It is cache hit ratio is low.
* Many requests are served from the publish instance
What should the DevOps Engineer use to analyze the issue?

Question6: An end user reports performance issues on the site. The AEM environment uses a CDM and a dispatcher as caching layers. The number of requests on the publish instance gas increased significantly.
Which metric can be monitored to see trends relate to the problem early enough to be able to react?

Question7: A DevOps Engineer receives notification from the monitoring system about a bundle being stuck in ''install'' state.
* A new version of an OSGi bundle was recently deployed.
* All author and publish instances are affected.
* Manually starting the bundle does not sole the issue.
What prevent OSGI bundle from the activated?

Question8: On which instance should a flush agent be configured to prevent invalidation timing issues after invalidation?

Question9: How can a DevOps engineer limit access to certain pages in the AEM Publish instance?

Question10: A DevOps Engineer is executing an online backup and wants to ensure consistency. This is a newer AWM version that uses Oak as a repository with multiple-version concurrent control.
What setting is no longer required to be set performing a backup to ensure consistency?

Question11: A company is launching a new multinational AEM site. The new site will has a large pool of authors all over the world. The company needs to be sure it can handle the load.
The load requirement for the new site are as follows:
* A daily load scaling from 100 to 1000 authors
* Create multiple pages and live copies (including ASM rollouts)
* Update 1000 tags to each new pages
What can the DevOps Engineer do to make sure the AEM instance can handle the load?

Question12: In what two ways can a DevOps engineer install a content package? (Choose two.)

Question13: Which transportUri should be used to configure a Flush Agent for a dispatcher listening on local host port
8000?

Question14: A DevOps Engineer is deploying an AEM environment in a private network.
How can the DevOps Engineer restrict other clients or applications from flushing the cache?

Question15: An AEM setup require custom error pages to be delivered by the webserver. The DevOps Engineer must configure the dispatcher so that the webserver deliver such error pages and not AEM. The webserver is configured with an error document directive for the specific error codes.
To what value should the dispatcher parameter be set?

Question16: According to Adobe best practices, how should a DevOps Engineer tailor OSGi Server configuration depending on the type of environment?

Question17: Why does the size of the repository double when running online compaction?

Question18: Which gate needs to be passed after the code is deployed?

Question19: New content is not visible on the website when accessing it via the dispatcher.
* Replication from author to publish works fine
* Dispatcher flush agent is present under/replication/agents. Author on the Publish instance and enabled
* The checkbox for Dispatcher flush agent confusion is ticked for enabled, when reviewed on the author instance Rules in the dispatcher flush agent is causing this issue?
