AEM service pack release notes typically include information that helps users understand the

changes that the service pack will bring to their AEM instance. These release notes commonly

include:

A) Deprecated features - This section informs users about the features that are being deprecated

with the current release and guides them on migrating away from deprecated features to the

recommended alternatives.

B) Known issues - This section provides information about any issues or bugs that are known at the

time of the release, which might not yet be fixed. It often includes workarounds for these issues if

they are available.

Option C, "Next service pack release date," is not typically included because release dates are subject

to change and are usually communicated through official channels closer to the actual release.

Option D, "Download link to AEM jar," is not included in the release notes but is typically available

through the Adobe Software Distribution site or Cloud Manager for AEM as a Cloud Service.

In HTL (HTML Template Language), data-sly-element is used to dynamically set the name of a DOM element. The provided option C correctly demonstrates the use of data-sly-element to replace the element name with the value of the titleLevel property of the model. The context 'unsafe' is specified because changing the element name can be a security risk if the value is not properly sanitized since it could lead to script injection vulnerabilities if used with user-provided data. Options A and B are incorrect because they don't use the data-sly-element attribute, which is necessary to dynamically change the tag name of the element in HTL.

In AEM, Lucene is often used for indexing due to its powerful full-text search capabilities, and it also

supports asynchronous indexing. Asynchronous indexing allows the system to handle other tasks

while indexing is being processed in the background, which can improve performance and scalability.

This is especially useful when multiple properties need to be indexed without impacting the

immediate response times of the system. Therefore, when a developer needs to enable the indexing

of multiple properties asynchronously, a Lucene index is the most suitable choice.

Given the dispatcher configuration snippet provided in the image, we can understand the URL

patterns that will be ignored (not cached) by the dispatcher. The configuration under

/ignoreUrlParams shows patterns to match query parameters in the URLs:

/0001 { /glob "*" /type "deny" } means that by default, all query parameters are ignored (not

cached).

/0002 { /glob "search" /type "allow" } specifically allows caching for URLs with the 'search'

parameter.

/0003 { /glob "order" /type "allow" } specifically allows caching for URLs with the 'order' parameter.

Based on this, let's evaluate the options:

A) /myproduct/myrecipe.html?search=searchparam — This URL will not be cached because the

'search' parameter is allowed, but the actual value 'searchparam' does not match any allow pattern.

B) /myproduct/myrecipe.html?search=s&order=asc&brand=ad — This URL will not be cached

because although 'search' and 'order' parameters are allowed, the 'brand' parameter is not allowed

according to the configuration. C. /myproduct/myrecipe.html?brand=mybrand — This URL will be

cached because there are no allowed parameters, so the default deny does not apply, and the page

can be cached without considering the 'brand' parameter.

Therefore, the page that will be cached on the dispatcher is the one in option C, as it does not

contain any of the explicitly allowed query parameters ('search' or 'order'), and all other parameters

are ignored by default.

The Discovery Service is an offloading-related service used by each AEM instance to connect to AEM

Topology Connector. The Discovery Service is part of the Sling Discovery framework, which is

responsible for detecting and managing the topology of AEM instances. It enables instances to

discover each other and establish a clustered topology, which is essential for load-balancing, failover,

and other distributed operations.

Option A, "Cluster Service," is not a standard term used in AEM for connecting to the Topology

Connector.

Option C, "Topology Connector Service," is a slightly misleading term; the correct term is Discovery

Service, which performs the role described.

When an AEM instance starts with specified run modes, it selects configurations from the repository

that match those run modes. Run modes allow for flexible management of settings and

configurations across different environments. For the instance started with 'author', 'dev', and 'emea'

run modes, it would apply configurations from paths that match these run modes.

Option B, /config/author.dev.emea.noldap, is correct. This path matches all three run modes

specified and would, therefore, be included.

Option D, /apps/mysite/config.author.emea.dev, is also correct. This path matches the run modes

and would be applied to the instance as well.

Options A and C do not match all three run modes and therefore would not be applied.

In a Maven project, the property is used to specify the version of the project itself. This version can include the version of the AEM project being built if that's the convention used in the project's versioning strategy. It's typically specified in the pom.xml file at the root of the project and is inherited by all the modules of the project unless they specify a different version locally in their respective pom.xml files.

In HTL, the format option in the data-sly-use or data-sly-test attribute can be used to format values

according to a pattern. The pattern '-#.##%' indicates that the number should be formatted as a

percentage with up to two decimal places. The piValue variable would be the number to format, and

in this example, it would convert -3.14 to -314%. The @ symbol is used to denote the use of an

option with the variable in HTL.

Options B and C are incorrect because they do not use the correct syntax for the format option in

HTL. The use of @ is to specify options and not part of the variable or pattern itself.

In HTL (HTML Template Language), the syntax to manipulate the URI path does not provide direct

methods for removing selectors. However, within Sling and HTL, the Link Handler can be extended to

support such operations. For out-of-the-box HTL, the proper approach to manipulate the link would

be done in the Java layer (e.g., a Sling Model or a Use-Class in HTL), and then passed to the template

for rendering. Nevertheless, if such a functionality were to be implemented within HTL, it would

require custom code and not use the indicated syntax options. It is important to note that options A

and B with 'removeSelectors' are not standard HTL syntax.

To create new content fragments programmatically in AEM, a developer would typically use an API

provided by AEM for content fragment operations. Among the options given,

FragmentTemplate.createFragment() seems to be the most fitting API method call, as it implies the

use of a template to create a fragment. In practice, the Content Fragment Java API provides methods

to create and manage content fragments in AEM by interacting with the underlying JCR (Java

Content Repository). However, without specific API documentation, I'm relying on provided patterns

that align with typical AEM Java API usage.
