How can Sling Models improve the performance of AEM components?
- By adding more annotations to the code
- By increasing the number of dependencies
- By reducing the number of resource resolution calls
- By using JavaScript instead of Java
Sling Models can improve the performance of AEM components by reducing the number of resource resolution calls, thus enhancing efficiency and response times. This is achieved by directly injecting resources into the Java code, avoiding multiple resource resolution operations.
Scenario: A company is concerned about the potential disruption caused by an AEM upgrade. What strategies can they adopt to minimize the impact on their existing AEM implementation?
- Conduct thorough testing, Implement a phased rollout, Provide training and support, Create backup and rollback plans
- Ignore the upgrade, Change company policies, Hire new employees, Reduce employee benefits
- Implement new HR policies, Expand business operations, Change employee work hours, Reduce employee salaries
- Increase advertising budget, Change office furniture, Update company website design, Conduct market research
Strategies such as conducting thorough testing, implementing a phased rollout, providing training and support, and creating backup and rollback plans can help minimize the impact of an AEM upgrade on an organization's existing implementation.
Sightly (HTL) templates are typically stored with a _______ extension in AEM.
- .html
- .jsp
- .sightly
- .template
Sightly (HTL) templates are stored with a .sightly extension in AEM, reflecting the template language used.
Scenario: You are tasked with optimizing an AEM component's performance. How can Sling Models assist in achieving this goal?
- By automating the deployment process
- By efficiently mapping Java objects to resource properties
- By enhancing the graphical user interface of the AEM component
- By managing user permissions within AEM
Sling Models help optimize performance by mapping Java objects to resource properties, reducing the need for boilerplate code and improving efficiency.

- Framework
- Language
- Platform
- Technology
AEM Core Components are designed to be framework-agnostic, allowing developers to use different front-end technologies based on their preferences and project requirements.
What is Cross-Site Scripting (XSS) in the context of AEM security, and how can it be mitigated?
- XSS is a content delivery network
- XSS is a database management tool
- XSS is a method to enhance website performance
- XSS is a type of security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users
Cross-Site Scripting (XSS) is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users, potentially compromising their data or hijacking their sessions. Mitigation involves input validation and output encoding to prevent script injection attacks.
