Right Answer:
I use the following debugging tools and techniques when troubleshooting issues in AEM:

1. **Sling Logging**: Adjust log levels and check logs in the Felix console for errors.
2. **AEM Error Logs**: Review error logs located in the `crx-quickstart/logs` directory.
3. **Sling Resource Resolver**: Use the resource resolver to inspect resource paths and properties.
4. **AEM Web Console**: Utilize the Web Console for OSGi services and configurations.
5. **Browser Developer Tools**: Inspect network requests and console errors in the browser.
6. **Debugging with Eclipse**: Set breakpoints and debug AEM code using an IDE like Eclipse.
7. **AEM Package Manager**: Check for package installation issues or conflicts.
8. **Replication Queue**: Monitor the replication queue for issues with content publishing.

Right Answer:
The RTE (Runtime Environment) manages inter-ECU communication by using a standardized communication mechanism that allows different ECUs (Electronic Control Units) to exchange data through defined interfaces. It utilizes the COM (Communication) module to handle message transmission and reception, ensuring that data is sent and received according to the AUTOSAR specifications, including support for different communication protocols like CAN, LIN, and Ethernet.

Right Answer:
Sender-receiver communication is a one-to-one communication model where a sender transmits messages directly to a receiver, typically used for periodic data exchange. Client-server communication, on the other hand, involves a client requesting services or data from a server, which processes the request and sends back a response, often used for more complex interactions and service-oriented architectures.

Right Answer:
An ALV (ABAP List Viewer) report is a tool in SAP that allows for the display of data in a structured and interactive format. To create an ALV report in ABAP, follow these steps:

1. Use the function module `REUSE_ALV_GRID_DISPLAY` or `REUSE_ALV_LIST_DISPLAY`.
2. Define the data structure and internal table to hold the data.
3. Populate the internal table with data from the database.
4. Define field catalog for column headers and attributes.
5. Call the ALV function module, passing the internal table and field catalog as parameters.

This will generate an interactive report with sorting, filtering, and layout options.

Right Answer:
Alfresco's key security features include:

* **Authentication:** Controls user login and identity verification.
* **Authorization:** Manages user permissions and access rights to content.
* **Encryption:** Protects data at rest and in transit.

* **Integration with External Security Systems:** Connects with LDAP, Kerberos, and other systems.

Right Answer:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."

Right Answer:
The Agile Manifesto values:

* **Individuals and interactions** over processes and tools.
* **Working software** over comprehensive documentation.
* **Customer collaboration** over contract negotiation.
* **Responding to change** over following a plan.

That is, while the items on the right have value, we value the items on the left more.

Right Answer:
Agile ceremonies are recurring meetings within a sprint to facilitate communication, planning, and continuous improvement.

* **Sprint Planning:** The team decides what work to complete in the upcoming sprint. They discuss user stories, estimate effort, and define the sprint goal.

* **Daily Stand-up:** A brief daily meeting where the team shares progress, identifies roadblocks, and coordinates efforts. Each member typically answers: What did I do yesterday? What will I do today? Are there any impediments?

* **Sprint Review:** The team demonstrates the completed work to stakeholders, gathering feedback and ensuring alignment with expectations.

* **Sprint Retrospective:** The team reflects on the past sprint, identifying what went well, what could be improved, and defining action items to enhance future performance.

Right Answer:
A sprint backlog is a detailed plan of work for a specific sprint, derived from the product backlog. It's created during sprint planning by the development team, who select items from the product backlog they commit to complete, then break down those items into tasks and estimate the effort required for each.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.
