AEM is a content management tool that supports the creation of content, mobile apps, and websites. The system enables experts in web development and digital marketing to create their own marketing plans for attracting customers.
The various interface types in AEM include the Touch UI Console, MCM Console, DAM Console, Launches Console, and Classic UI Homepage.
To determine how the website’s elements function, components are used. They are reusable and can contain other configuration files. They can be edited and have a user interface. They can be launched into live sites and test environments.
We can use a dialogue grid-using component as an example. The steps to make the AEM component are:
All of the client-side code, as well as Javascript and CSS resources like fonts, sprites, and colors, are managed by the AEM client library. We can maintain, debug, merge, and use less code and resources thanks to it.
Custom tag libraries can be developed using AEM. This makes it easier for an AEM component to call or invoke its actions. These actions can be invoked using XML code.
Dispatcher is a tool used in AEM that helps with caching and load balancing. The device can be viewed as an option for the AEM server’s security enhancement against external attacks.
Publishing page content from an Author Instance to a Process Instance is known as replication in AEM. It is also used to filter content from Dispatcher cache. From the publish environment to the author environment, user data is transferred.
If the AEM replication fails, the appropriate course of action must be taken. You can check if replications are queued in the replication agent queues by going to the /etc/replication/agents directory. author. html. Click replication agents to analyse the situation.
The content is moved from the publisher environment to the author environment during reverse replication. It is used to replicate information about a user’s profile details and forum posts on the website.
We can activate the debugger mode by starting the AEM in debug mode. The command line needs to be updated with the following code:
Sling is used to develop web applications in AEM. Web apps with a focus on content can be created using the framework. It is built on top of JCR (Java Content Repository) and is based on REST principles. It is employed to handle and store content on the Java Repository.
In order to call a service from a sling model in AEM, a custom component with a TreePanel type object must be created.
Redefining and customizing the current functionality is known as overlay in AEM. Making a custom component may involve modifying the current foundation component in accordance with specifications. Recommended Posts:
AEM INTERVIEW QUESTIONS 2+ years to 6+ years
Multiple CQ Publisher instances in various environments (such as DEV, QA, PROD, etc.) are typical. ). You might want to move users and groups down to the lower DEV and QA environments when you make user administration and security changes to users and groups on the production server so they don’t become out of sync. In this case, you must copy both the permission definition and the user/group definition. This article demonstrates how to transfer permissions (resource-based ACLs) from one CQ instance (the source CQ) to the destination CQ, as well as how to copy users and groups you’ve created on the source CQ to the destination CQ.
The key takeaway is to treat your content as a Big Flat List if it’s hierarchical rather than trying to treat it that way, especially if you’ll be doing a lot of updates. (However, it doesn’t really matter if you’re doing mostly reads and few writes. ) Your content organization scheme will benefit greatly from some hierarchy, which will help to promote fast update performance.
Friends, this blog post might be somewhat tricky and thought-provoking . The following questions are essentially business scenarios that are asked in interviews, and you are expected to think about them and come up with the most workable solution. The answers to these questions might differ approach to approach. You might be able to come up with a better answer, or perhaps the solutions I have provided below will help you think more broadly. If you have a better solution for them, please let me know. I would be happy to add it here.
Thousands of sibling nodes, for example, under a single parent node, can cause write performance to suffer even though read performance is still good. This is because TarPM is an append-only store where objects are immutable and are only ever rewritten, never overwritten. In other words, the price of adding (or updating) Node No N-thousand-plus-one can be quite high.
Q3. You may be aware that a back-end workflow is started whenever I upload a DAM asset in AEM. I need to upload roughly 3000 dam assets of various sizes to my AEM instance, but I don’t want to overwhelm my instance with a large number of workflows at once. How shall I go about it?.
Q13. (Pretend you have two components, one with a dialog A and the other with a dialog B. How will you go about using a user input from dialog A into dialog B? You want to use that other dialogA’s tab into dialogB.
Q15. ) Assume your project includes NEWS Pages and Article Pages. Using the Related NEWS component, each article page can link to the NEWS pages. Additionally, every NEWS page ought to include a RELATED Articles component with a list of articles where it is present. How will the solution be created, taking Caching Strategies and Authoring Convenience into consideration?
Alternatively, you may use InheritanceValueMap to achieve this task. This interface is meant to make it much easier for developers to access properties inherited from parent pages. To do this, the interface provides two methods, getInherited(String, Class) and getInherited(String, Object), each of these methods will check for a value on the current resource and then check up the page hierarchy for another page with a value on the same content attribute. It will only attempt to retrieve values at the same page content path.
Q14. ) Consider there are 3 components: 1. Component A ———A. jsp ————-output T1 2. Component B ———B. You want to create a component C (sling:resourceType is B) and a component D (sling:resourceSuperType is B), and you only need an output of T3 for these components. jsp ————-output T2; sling:resourceSuperType is A Which jsps you may override in both the cases individually?.
The property might be present on any page in the hierarchy, so getting a property on that page is the first option you might consider. If the property isn’t there, iterate to the parent page, check the property there, iterate back to the original page, etc. But this is a Brute-force method. Not at all appreciated.

What is difference between AEM and CQ5?
The only difference I could find between the examples when I looked at them was the UI of WCM. e. Although it has a new appearance and feel, you can still use the classic mode. CQ5 still encourages coding in JSP i. e. it still uses scriplets. Is there any alternative to using Scriptlets in AEM 6. x?.
Is AEM good for Career?
Because of the increasing demand and need for AEM developers in a company, a career as an AEM developer is not only a good idea but also very rewarding and lucrative. Additionally, you will enjoy job security and a high salary in this industry.
What coding language is used in AEM?
Front End Development AEM uses HTML Template Language (HTMLTL) for front end custom development. HTL is similar to JSP in that it combines HTML and unique directives. It is safe to use, and you don’t need to know Java to program in it.
