Q. Explain the difference between CQ5.4 and CQ5.5.
Before version 5.5, CQ was built on a servlet container (CQSE by default, but others may be used) that ran multiple web applications: one for the CRX content repository and another for the OSGi container, which contained Sling and AEM. The majority of the request processing was handled by the Sling web app, which was connected to the root. The following are some points to remember for CQ5.5:
The OSGi container is at the root of CQ 5.5 and AEM, with the OSGi HTTP service, supported by Sling, acting as the only request handling endpoint.
Along with the many services that make up the rest of the AEM functionality, the CRX content repository is now just another OSGi service. These modifications have no impact on AEM or Sling-based apps.
Because of the new design, AEM’s quickstart jar installation can no longer enable the use of other web applications alongside AEM.
The war version of AEM, on the other hand, is designed to be installed in an application server alongside other web applications.
Three new connectors for Adobe products – Creative Suite, Scene7, and Search&Promote – have been added.
The authors will be able to work directly on mobile applications.
Hybrid software was partnered with to give some wonderful eCommerce functionality.
Undo(Ctrl+z) and Redo(Ctrl+y) functions have been added.
Q. What is AEM Testing?
Q. In AEM, what is a template?
A Template helps you to set a uniform style for your application’s pages. It also specifies which components (reusable modules) are permitted to be used within the scope chosen. It’s a tree of nodes with the same structure as the page you’re going to make. It is devoid of any actual content. AEM offers static as well as editable templates. Templates are used in AEM at several points:
When building a new page, you would first choose a template that will serve as the foundation for the new page. The template specifies the structure of the final page, as well as any starting content and possible components (design properties).
You would also choose a template when generating a Content Fragment. The structure, basic elements, and variants are all defined in this template.
Q. What are AEM Connectors?
The AEM Connector works with a wide range of search systems, from open-source like Elasticsearch and Solr to commercial solutions like Azure Search, SharePoint Search, Endeca, and others, similar to our search engine independent connectors. The AEM connector allows businesses to scan and publish their websites and digital assets from within an AEM server to their existing search engines. This allows all search tasks to be completed within the search engine, minimising the AEM server’s processing burden and offering a variety of search capabilities, from basic to advanced.
It has throttling tools and procedures to control the number of requests made in a given time period, allowing the connector to send many queries to the AEM server without affecting its performance or availability. It allows exclusive individuals and groups to securely view the documents meant for them.
Q. What is the definition of a content repository? What exactly is JCR (Java Content Repository)?
A content repository is essentially a storage location for digital content. The content repository’s structure is often hierarchical and represented as a tree structure, with each node of the tree serving as a storage location for content.
Java Content Repository is a Java community specification for accessing content repositories in a consistent manner (platform-independent and vendor-independent way). JSR-170(JCR 1.0) was the first version of the specification, and version 2 was released subsequently (JCR-283). The javax.JCR API gives access to a content repository through multiple classes and interfaces.
Q. What is the foundation of CQ5’s technology stack?
Three technologies make up the CQ5 technological stack. Apache Sling, OSGi (Apache Felix), and the Java Content Repository (JCR) are the technologies in the discussion. Apache Sling is a RESTful framework for interacting with a JCR via the HTTP protocol. The request URL will then be mapped to the JCR node. OSGi is a Java framework that allows for the construction of modular applications. During runtime, each module, referred to as a bundle, can be stopped and started individually. The JSR-170 API is used by the Java Content Repository to access the content repository using Java, regardless of the physical implementation. CQ5 uses CRX, which is its own JCR implementation.
Q. What is sightly in AEM?
In AEM 6.0, Sightly was introduced as an HTML templating language. It is intended to replace JSP files and is the primary HTML templating solution. The word “sightly” implies “pleasant to the eye,” and its goal is to make your markup look nice and tidy. The following benefits of using Sightly:
Lightweight — There are no dependencies, thus it is quick and lean.
Secure – Contextual XSS (Cross-site scripting) prevention and URL externalisation are both automatic.
Powerful – A simple logic API that allows you to perform almost anything.
Intuitive – A feature set that is clear, basic, and limited.
Q. What is the need for a Content Management System (CMS)?
A content management system (CMS) is a chunk of software for creating and managing files and Web sites. Since a lot of websites and web applications are dynamic, their content must be updated on a regular basis. It is advised that you use a content management system to effectively handle these modifications. Adobe Content Management System is one of the numerous CMS suppliers accessible.

Q. What is AEM Brackets Extension?
The AEM Brackets Extension provides a smooth workflow to edit AEM components and client libraries and leverages the power of the Brackets code editor, which gives access from within the code editor to Photoshop files and layers. The easy synchronization provided by the extension (no Maven or File Vault required) increases developer efficiency and also helps front-end developers with limited AEM knowledge to participate in projects. This extension also provides some support for the HTML Template Language (HTL), which takes away the complexity of JSP to make component development easier and more secure.
Q. What do you understand by extending a component?
Extending components means add complexity and verbosity to your code, and in some cases, additional performance overhead.
Q. What is FileVault Tool (VLT) in AEM?
The full form of VLT is the Jackrabbit FileVault tool. It is a tool developed by The Apache Foundation that maps the content of a Jackrabbit/AEM instance to your file system. It has similar functions as a source control system client such as a Subversion (SVN) client. It provides normal check-in, check-out, and management operations, as well as configuration options for flexible representation of the project content.
