AEM also makes asset management more accessible by allowing you to use all of your marketing assets across all digital channels. Several significant corporations use AEM as their content management system.

2. What design patterns are used in AEM?

Since  AEM is built with OSGL, many of the OSGI design patterns are applicable. These design patterns are Singleton (services), adapter service, resource adapter services, and whiteboard. You should also be able to utilize design patterns in your application because AEM is modular.

3. What is the role of AEM Architechs?

The AEM Architect will be a team member tasked with developing a world-class Adobe Experience Manager (AEM) implementation.

4. What is Adobe Marketing Cloud, and how does it work?

The Adobe Marketing Cloud is a one-stop solution for all customers, allowing them to use these services and ensure that their digital marketing side is fully covered by utilizing Adobe services.

5. Write out all the available interfaces in Adobe Experience Manager.

The list of all available in Adobe Experience Manager is as follows:

CRX Explorers

CRX Delite

Apache Felix

Site Admin

Etc/Tool

6. What is the procedure for starting AEM in debug mode?

We can enable the debugger mode by starting the AEM in debug mode.

Nofork -agentlib:jdwp=transport=dt socket,server=y,suspend=n,address=10123 needs to be included to the command line.

7. What is the tag library in AEM?

Custom tag libraries can be created utilizing AEM. This facilitates the calling or summoning of its activities from an AEM part. These activities can be summoned using XML code.

8. What is an overlay in AEM?

Overlay in AEM is the most well-known method of reevaluating the current convenience and modifying it. It might be making a custom part by differing the everyday foundation partly according to necessities.

9. What happens in AEM if replication fails?

If the AEM replication fails, the appropriate action must be performed based on the circumstances. It is possible to check if images are queued in the replication agent queues by going to /etc /replication/agents. Author. HTML. To investigate the situation, click replication agents.

10. What is CQ in Adobe CQ5 CMS?

CQ means communique in adobe CQ5 CMS.

11. What is the AEM Dispatcher’s role?

The dispatcher is an AEM caching and loads balancing utility. The dispatcher can also help keep your AEM server from assault because it will be retrieving cached pages. The dispatcher’s goal is to save as much content as possible so that the layout engine isn’t used. Load balancing is a method for distributing the computational load of a website across numerous instances of AEM.

12. State the benefits of using the AEM Dispatcher?

The benefits of employing the dispatcher as a load balancing tool include increased processing power and increased fail-safe coverage because the dispatcher shares document requests amongst multiple instances of AEM. This is performed by the dispatcher automatically relaying the request to another model if it does not receive responses from one example.

13. What is the need for a content management system (CMS)?

A content management system (CMS) is software for creating and managing documents and websites. Because many websites are active, their content must be updated regularly, and it is advised that you utilize a content management system to handle these modifications effectively. There are numerous CMS suppliers to choose from, and one of them is the Adobe Content Management System.

14. What is sightly?

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 keep your markup looking beautiful and sustainable.

15. Is it possible to make a page without using a template?

When you create a page in the website console, you usually choose a page template. Using the same options in the website interface to generate a page can be manually created in crude. Create a node in crxde with the type “CQ: page” and save it, for example, in the content folder. Then, add a child node in the tree with the class “CQ: Page content.” Following that, you can make the necessary adjustments to display any components you want on the website. Creating pages by hand is generally not a brilliant idea.

16. What is a replicant agent?

To post active material to the flush content, publish environment from the dispatcher cache, and restore user input to the author environment from the publish environment, the author environment uses a replicant agent. AEM makes extensive use of replicating agents.

17. What are xtypes, and how may they help you with AEM?

An xtype is a representational name for a class in the ExtJS language. These xtypes are appliances in AEM that are used to create the component. AEM has come up with several devices that are ready to use right now. You may also utilize AEM to develop and specify your xtype. An xtype is something like this: If you need the author to be allowed to register text in your component’s dialogue, use a “CQ: Widget” with the xtype option “text field” when creating the conversation.”.

18. State the difference between a dialog and a design dialog?

Dialogue is an essential part of the component since it gives authors a way to set up and input data. This information will be saved at the page grade in the JCR; a design dialogue appears only while you’re in the design mode of AEM. The information you provide here will be saved at the pattern level and accessible throughout the site.

19. What is meant by reverse replication?

Reverse replication is the method of replicating content from publish environment to the author environment. To achieve this, you need a reverse replication agent on your author instances. It is set up to receive content from the publish environment’s outbox.

20. Differentiate author and published environment?

AEM usually runs in two different instances in a production environment. The author’s example is one, and the published example is another. Usually, these two examples are kept in separate settings. You’ll register and administer material for your website in the author instance. This is also where you will manage your webpage. Typically, the author’s environment is kept after a firewall. You’ll create your content accessible to your selected audience in the publish instance. In most cases, the publishing environment is preserved in a demilitarised zone (DMZ).

21. Define resource mapping, and how does it work?

AEM uses resource mapping to determine vanity, URLs, redirects, and virtual hosts. You can custom resource mapping to attach all requests with “/content” to hide the AEM site’s internal structure from visitors. You may also utilize resource mapping to create a redirect that sends all applications to your site’s gateway page to another place.

22. What is the definition of a component?

Components are reusable modules that implement specific application logic to render your website’s content. A component can be viewed as a collection of scripts (for example, JSPs, Java servlets, and so on).

23. What’s the best way to get digital items into the dam?

You may add a digital bundle to your project by browsing the source folder under “apps” in crdx. After that, right-click the “source” folder and select “make a bundle.” This will launch the wizard, which will guide you through the process of generating your package. It is no longer advised to utilize crxde to produce OSGI bundles for AEM. Instead, Maven should be used.

24. What is a component’s extension?

Extending a component means creating a new feature that does not overwrite a base component but has the same characteristics as the original so you can update or build on it. You must “sling: resource supertype” the part you want to extend to the base component you wish to raise. You’ll get everything from the base component if you do it this way.

25. List out some of the benefits of adopting OSGI?

The key advantages of utilizing OSGI are:

It simplifies the system by putting everything in bundles.

Since the components can be installed, uninstalled, updated, launched, and terminated at runtime. They are loosely connected and straightforward to handle.

It improves system performance because elements of the application that aren’t in use don’t have to be loaded into memory.
