In OSGi bundle Activator.java is registered through a service DevelopInfo.java DeveloperInfo.java

Activator.java

Maven install generates an error during deployment. Refer to the error information below:

Which action should the developer take to resolve the build error?

• A. @Service annotation is missing in DeveloperInfo.java.
• B. Interface DeveloperInfo does NOT have any method.
• C. Activator class is NOT implementing DeveloperInfo interface.
• D. The required Maven repository for OSGi is missing.

A developer determines that the dispatcher is NOT refreshing the cached page
/content/sampleproject/sample.html after it is updated.
The dispatcher.any contains the following entries:
/cache
{
/docroot "/opt/dispatcher/cache"
/statfile "/tmp/dispatcher-website.stat"
/statfileslevel "2"
/rules
{
/0000 { /glob "*" /type "allow" }
}
/invalidate
{
/0000 { /glob "*" /type "deny" }
}
}
Refer to the $DOCROOT directory below:
[user@group /opt/dispatcher/cache]$ ls -la
total 2
drwxr-xr-x. 5 apache apache 4096 Feb 11 11:41 .
drwxr-xr-x. 3 apache apache 4096 Nov 29 16:07 ..
drw-r--r--. 4 root root 4096 Feb 7 03:21 content
-rw-r--r--. 1 apache apache 0 Feb 7 03:19 .stat
The dispatcher needs to cache the page and refresh it after it gets updated.
What action should the developer take to meet these requirements?

• A. Remove /statfile or /statfileslevel
• B. Add the entry /0001 { /glob "*.html" /type "allow" } in the /invalidate section
• C. Change the value of the entry /statfileslevel to "3"
• D. Delete the contents of the DOCROOT directory

A developer creates a custom Client Library named foobar.
This Client Library embeds 5 other Client Libraries and contains 10 JavaScript source files. One of these files, called foo.js, has a bug on line 8 which causes an exception. The Client Library is throwing this exception on line 1350 when it is included on a webpage.
How should a developer find the exact line in foo.js where the exception has been thrown?

• A. 1. Enable JS/CSS minification in OSGi configuration console for HTML Library Manager.2. Check the JavaScript exception log in the OSGi web console.
• B. 1. Add the selector debugClientLibs to the page request.2. Check the JavaScript exception log in the OSGi web console.
• C. 1. Temporarily remove the embedded Client Libraries of the foobar Client Library.2. Use the browser JavaScript debugging tools.
• D. 1. Add the query parameter debugClientLibs=true to the request.2. Use the browser JavaScript debugging tools.

After adding new features, a developer's environment is experiencing slowness before ultimately running out of memory. The initial log analysis points towards a large number of open sessions.
Which action should the developer take to further monitor the overall session count on this AEM instance?

• A. Go to Tools > Operations > Monitoring. Create a new report based on Number of Active Sessions as metric.
• B. Go to Web Console > Status > Threads, verify the overall thread count.
• C. Go to <aem-install>/crx-qiuckstart/logs/strderr/log, use the following command grep -o
  'CRXSessionImpl' strderr.log| wc -l.
• D. Run the following command to generate thread dumps jstack -l <pid> >> threaddumps.log, analyze thread dumps to find long running sessions.
