AEM administrators can prevent common security misconfigurations by implementing a combination of measures, including regularly updating AEM and its dependencies to patch vulnerabilities, implementing proper authentication and authorization mechanisms to control access to resources, and monitoring system logs for suspicious activities to detect and respond to security threats in a timely manner.

Common techniques for troubleshooting AEM caching issues include clearing Dispatcher cache, adjusting caching settings in AEM, and analyzing cache headers to ensure optimal performance.

In Sightly (HTL), the data-sly-list attribute is used for iterating over a list of items, enabling the dynamic generation of content based on the data.

AEM Content Fragments can be rendered as responsive designs, adapting to various channels and devices for a consistent and optimized user experience.

The "Error Handler" in an AEM workflow is responsible for handling exceptions that may occur during the execution of the workflow, ensuring smoother workflow processes.

AEM Core Components are reusable building blocks designed to accelerate website development in AEM, providing consistent and efficient components for common functionalities.

The Design dialog in AEM Component Libraries is employed to define component-specific design properties, contributing to the overall visual consistency.

The primary types of caching in AEM include Dispatcher Caching, Page Caching, and Component Caching, each serving specific purposes to optimize content delivery.

Having a robust backup strategy is crucial during AEM maintenance to revert to a stable state if any issues occur.

AEM's architecture allows for horizontal scalability, enabling the system to handle increased traffic by adding more instances in a distributed environment.
