- Content fragmentation, distributed caching, static content generation, and synchronous replication
- Custom authentication, session management, dynamic component rendering, and server-side scripting
- Single server deployment, manual backups, regular updates, and load balancing
Achieving high availability and failover in AEM involves strategies like clustering, redundant servers, geographic distribution, and automated backups to ensure continuous operation and minimize downtime.
Scenario: An AEM application is frequently encountering errors in the logs related to database connections. What steps would you take to troubleshoot and resolve this issue?
- Check Network Connectivity
- Increase Server RAM
- Review Database Configuration
- Update AEM Version
Troubleshooting database connection errors involves reviewing the database configuration in AEM, ensuring proper credentials and connectivity settings are in place.
AEM best practices recommend regular _______ of the project's codebase to identify and address issues.
- Code Audits

Regular Code Audits are recommended in AEM projects to identify and address issues, ensuring the project's codebase remains robust and scalable.
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.
AEM Core Components are designed to be _______-agnostic, allowing flexibility in front-end development.
- 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.
AEM administrators should regularly review and update _______ policies to align with security best practices.
- Access Control
- Backup
- Versioning
- Workflow
AEM administrators should regularly review and update Access Control policies to align with security best practices, ensuring proper permissions and authorization.
