20. How can you optimize the performance of an AEM application?
To optimize the performance of an AEM application, you can use techniques such as caching, asset optimization, image compression, and code optimization. Additionally, you can leverage the Dispatcher module and CDN (Content Delivery Network) for efficient content delivery.

1. What is Adobe Experience Manager (AEM)?
Adobe Experience Manager (AEM) is a content management system that allows organizations to create, manage, publish, and optimize digital experiences across various channels, such as websites, mobile apps, and social media.

2. What is the architecture of AEM?
AEM follows a modular architecture that consists of different layers, including presentation layer (user interface), service layer (business logic), and storage layer (content repository). The content repository is based on Apache Jackrabbit Oak.

3. What are the key components of AEM?
Some of the key components of AEM are:
– Authoring Environment
– Content Repository
– Dispatcher
– Search Engine
– DAM (Digital Asset Management)
