Right Answer:
Classical reports display data in a simple list format without user interaction, while interactive reports allow users to drill down into data, filter, and navigate through different levels of detail.

Right Answer:
Common integration KPIs or metrics to track include:

1. **Integration Success Rate** - Percentage of successful integrations versus total attempts.
2. **Error Rate** - Number of errors encountered during integration processes.
3. **Response Time** - Time taken for the integration to respond to requests.
4. **Throughput** - Number of transactions processed in a given time frame.
5. **Latency** - Delay between request and response in the integration.
6. **System Uptime** - Percentage of time the integration services are operational.
7. **Data Accuracy** - Percentage of data correctly integrated without discrepancies.
8. **Resource Utilization** - CPU, memory, and network usage during integration tasks.
9. **Time to Integrate** - Duration taken to complete the integration process.
10. **User Satisfaction** - Feedback from users regarding the integration performance.

Right Answer:
To upgrade from one version of AEM to another, follow these steps:

1. **Review Release Notes**: Check the release notes for the new version to understand new features, deprecated features, and breaking changes.
2. **Backup**: Create a complete backup of your current AEM instance, including the repository, configurations, and custom code.
3. **Set Up a Test Environment**: Clone your current environment to a test instance for the upgrade process.
4. **Upgrade Process**: Follow the official Adobe documentation for the upgrade process, which typically involves:
- Downloading the new AEM version.
- Stopping the current AEM instance.
- Replacing the AEM jar files with the new version.
- Running the upgrade scripts if necessary.
5. **Migrate Custom Code**: Review and update any custom code or configurations to ensure compatibility with the new version.
6. **Testing**: Thoroughly test the upgraded instance for functionality, performance, and any issues.
7. **Deploy**: Once testing is successful, plan and execute the upgrade on the production environment.
8. **Monitor**: After the upgrade, monitor the system for any unexpected behavior or issues.

Right Answer:
Common types of linking errors include:

1. **Undefined References**: Occurs when a function or variable is declared but not defined. Resolve by ensuring all referenced functions/variables are defined and linked correctly.

2. **Multiple Definitions**: Happens when the same function or variable is defined in multiple files. Resolve by using `extern` for declarations in header files and ensuring only one definition exists.

3. **Library Not Found**: Occurs when the linker cannot find a specified library. Resolve by checking the library path and ensuring the library is correctly installed and linked.

4. **Incompatible Object Files**: Happens when object files are compiled with different settings or incompatible versions. Resolve by recompiling all object files with consistent settings.

5. **Symbol Conflicts**: Occurs when two or more symbols have the same name. Resolve by renaming conflicting symbols or using namespaces.

6. **Incorrect Link Order**: Happens when libraries are linked in the wrong order, causing dependencies to be unresolved

Right Answer:
AEM (Adobe Experience Manager) architecture is based on three core components:

1. **Sling**: A web framework that maps HTTP requests to content resources. It allows developers to create dynamic web applications by using a resource-oriented approach, enabling easy access to content stored in the JCR.

2. **OSGi**: A modular system and service platform that allows for the dynamic loading and unloading of components (bundles). In AEM, OSGi manages the lifecycle of these components, enabling modular development and deployment.

3. **JCR (Java Content Repository)**: A specification for a content repository that stores and manages content in a hierarchical structure. AEM uses JCR to store all content, including pages, assets, and configurations, allowing for efficient content retrieval and management.

Together, these components enable AEM to deliver a flexible, scalable, and efficient content management solution.

Right Answer:
Flask is a lightweight web framework for Python that allows developers to build web applications quickly and easily. It is designed to be simple and flexible, providing the essential tools to create web services and applications.

Right Answer:
A pivot table is a data processing tool that summarizes and analyzes data in a spreadsheet, like Excel. You use it by selecting your data range, then inserting a pivot table, and dragging fields into rows, columns, values, and filters to organize and summarize the data as needed.

Right Answer:
The purpose of feature engineering in data analysis is to create, modify, or select variables (features) that improve the performance of machine learning models by making the data more relevant and informative for the analysis.

Right Answer:
SQL (Structured Query Language) is used in data analysis to query, manipulate, and manage data stored in relational databases. It allows analysts to retrieve specific data, perform calculations, filter results, and aggregate information to derive insights from large datasets.

Right Answer:
Clustering in data analysis is the process of grouping similar data points together based on their characteristics, without prior labels. It is an unsupervised learning technique. In contrast, classification involves assigning predefined labels to data points based on their features, using a supervised learning approach.

Right Answer:
1. Remove duplicates
2. Handle missing values
3. Correct inconsistencies
4. Standardize formats
5. Filter out irrelevant data
6. Validate data accuracy
7. Normalize data if necessary
