How can the DevOps Engineer prevent any user from logging in with the default admin credentials during startup of the AEM instance?

Change the default AEM admin password on initial setup

Update the default password in the OSGi configuration for the OSGi web console

Change the default AEM admin password on initial setup

Configure the dispatcher to prevent access to /system/console

Disable the OSGi web console login bundle by using the production ready runmode

When configuring replication agents, under which path of the repository are agents stored for the AEM author instance?

/etc/replication/agents.author D./etc/author/agents/replication

A DevOps Engineer receives notifications from the monitoring system about a bundle being stuck in “installed” state.A new version of an OSGi bundle was recently deployed.All author and publish instances are affected.Manually starting the bundle does not solve the issue.What prevents the OSGi bundle from being activated?

At least one OSGi component throws an exception during activation.

At least one OSGi component has ConfigurationPolicy set to “required” and no configuration is provided.

At least one OSGi bundle marked as a dependency is not available in the instances.

At least one OSGi component reference is unsatisfied.

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

rlog.jar to analyze request.log

rlog.jar to analyze dispatcher.log

rlog.jar to analyze request.log

jtail.jar to analyze access.log

AEM author instance has been unstable and unresponsive.Restarting the instance resolves the issue temporarilyServer disk space and CPU utilization seems fineTop and free command shows enough memoryThe following error appears in the logs: “java.lang.OutOfMemoryError: gc overhead limit exceeded” Which JVM parameter should the DevOps Engineer add to troubleshoot?

-XX:+HeapDumpOnOutOfMemoryError

-XX:OnOutOfMemoryError='kill -3 %p'

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

“Current cache hit ratio” in the dispatcher.log

Output from the request.log in measuring response time

“Current cache hit ratio” in the dispatcher.log

The DevOps Engineer sees many occurrences of org.apache.sling.api.resource.LoginException in the logs.Apache Sling Service User Mapper Service is configured with a default user.Service user mapping is configured for the OSGi bundle, causing the exception.What is the root cause of these exceptions?

Administrative resource resolvers have been disabled by configuration and the bundle deployed still relies on it.

There is no service user mapping configured for the Java class causing the exception.

The exceptions relate to failed login attempts with incorrect credentials.

The configured service user is not a system user or does not exist.

Administrative resource resolvers have been disabled by configuration and the bundle deployed still relies on it.

A company is launching a new multinational AEM site. The new site will have a large pool of authors all over the world. The company needs to be sure it can handle the load.The load requirements for the new site are as follows:A daily load scaling from 100 to 1000 authorsCreate multiple pages and live copies (including MSM rollouts)Upload multiple images into AssetsAssign 1000 tags to each new pagesWhat can the DevOps Engineer do to make sure the AEM instance can handle the load?

Use standard Cloud Manager tests

An AEM instance is restarted with the command: java -Dsling.run.modes=author -jar cq-publish.jar -r author. The sling.properties includes the line sling.run.modes=publish.In which runmode is AEM started?

Publish runmode because it is determined from the quickstart jar filename

Author runmode because the -r parameter has the highest priority

Publish runmode because it is determined from the quickstart jar filename

Author runmode because the system property sling.run.modes has the highest priority

Publish runmode because the sling.properties file has the highest priority

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?

Set up client certificate authentication in the dispatcher configuration

Set permissions on the publish instance by using Access Control Lists to allow the publish instance private IPs

The allowedClients section in the dispatcher configuration should only allow the publish instances private IPs

Configure the /filter section of the dispatcher configuration with an allow rule to make sure the correct client's private IPs are allowed to flush the cache

According to Adobe best practices, how should a DevOps Engineer tailor the OSGi service configurations depending on the type of environment?

Leverage configuration files in runmode dedicated folder

Leverage multiple content packages for each environment

Use environment variables to identify the instance and environment type, then load the appropriate configuration files accordingly

Provide default configuration in the content package, and apply the differences using the OSGi console
