AD0-E116: Adobe Experience Manager Sites Developer Expert

There are performance, stability, and security issues with an installed AEM instance. What should a developer do to fix these issues?

A developer has a component named foobar with the following file: foobar.html:

< div data-one="${'foo'}" data-two="${2}" data-three="${true}"></div >

< div data-one="${''}" data-two="${0}" data-three="${false}"></div >

What is the output when the component is rendered?

A developer needs to create a component with the following requirements:

* The component must be configurable

* The component should be editable, NOT removable

* An author should be unable to add the component to a page through design mode

Which mode structure should the developer use to meet these requirements?

A developer creates a custom component. The component dialog includes the following two fields:

he component should display the first ‘X’ characters of the text entered in the ‘text’ input where ‘X’ is the number entered in the ‘charLimit’ input. If zero, or no value, is entered in the ‘charLimit’ input then the text should be unaltered. The developer creates the following Sling Model to perform the trancation:

A Null Pointer Exception occurs if NO charLimit values is set in the component dialog. What should the developer do to resolve this issue?

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 custom AEM application is using the PageManager API.

What should a developer add to make the application compile and run correctly in AEM?

A developer is working with the following HTL expression in a component rendering script:

${'path/page.infinity.json' @extension = 'html',

removeSelectors = ['foo'],

selectors = ['foo', 'bar'],

prependSuffix = 'hello', suffix = 'world' }

What is the expected output of this expression?

A developer needs to create a banner component. This component shows an image across the full width of the page. A title is shown on top of the image. This text can be aligned to the left, middle, or right. The core components feature a teaser component which matches almost all requirements, but not all.

What is the most maintainable way for the developer to implement these requirements?

A developer needs to ensure that the path /content/<proj>/segments exists on all environments with the correct initial content that the developer provides in a package. Content that exists in that path should NOT be affected. Which import mode should the developer use in the filter definition?
