Ques:- How does RTE manage inter-ECU communication
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.
Ques:- How do you define and manage document workflows in Alfresco
Right Answer:
In Alfresco, document workflows are defined using BPMN 2.0 process definitions. These definitions are managed and deployed via the Alfresco Process Services (APS) engine, often integrated with Alfresco Content Services (ACS). You can use tools like Activiti Designer to create the BPMN definitions, then deploy them to APS. In ACS, users can then initiate these workflows on documents, and tasks are managed through the Alfresco Share interface or custom applications using the Alfresco APIs.
Ques:- How do you manage permissions and roles in Alfresco
Right Answer:
Alfresco manages permissions and roles through a hierarchical model using Access Control Lists (ACLs). Permissions are granted to users or groups on specific nodes (folders/documents). Roles are predefined sets of permissions. Users inherit permissions based on their roles and group memberships. Administrators can manage these through the Alfresco Share interface or using the Alfresco API.
Ques:- What are client libraries (clientlibs) in AEM and how do you use them for front-end resource management
Right Answer:
Client libraries (clientlibs) in AEM are collections of front-end resources, such as CSS and JavaScript files, that are organized for efficient loading and management. They allow developers to group related assets, define dependencies, and optimize resource delivery. To use clientlibs, you create a folder structure under `/apps` or `/libs`, define a `clientlib` node with properties like `categories` and `js`/`css` arrays, and include them in your AEM components or pages using the `cq:includeClientLib` or `data-sly-include` methods.
Ques:- What are the key components of the Alfresco architecture
Right Answer:
The key components of the Alfresco architecture are:

* **Alfresco Content Repository:** The core content store.
* **Alfresco Share:** The web-based user interface.
* **Alfresco Process Services (Activiti):** The workflow engine.
* **Search Subsystem (Solr or Elasticsearch):** Provides search capabilities.
* **Transformation Framework:** Enables content transformations.

Ques:- What is the difference between a user story, a task, and an epic in Agile
Right Answer:
* **Epic:** A large, high-level user story that is too big to complete in a single iteration. It's usually broken down into smaller user stories.
* **User Story:** A small, self-contained requirement that represents a valuable piece of functionality for the end-user. It follows the format: "As a [user type], I want [goal] so that [benefit]".
* **Task:** A small, actionable item that needs to be done to complete a user story. It's a technical breakdown of the work required by the development team.
Ques:- Can you explain the key principles of the Agile Manifesto
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.
Ques:- Can you describe a time when an Agile project didn’t go as planned and how you handled it
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."
Ques:- What is Scrum, and how do you implement it in software development projects
Right Answer:
Scrum is an Agile framework for managing and completing complex projects.

Implementation involves:

1. **Roles:** Defining roles like Product Owner, Scrum Master, and Development Team.
2. **Sprints:** Working in short, time-boxed iterations (Sprints), typically 2-4 weeks.
3. **Artifacts:** Using artifacts like Product Backlog, Sprint Backlog, and Increment.
4. **Events:** Conducting events such as Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
5. **Continuous Improvement:** Regularly inspecting and adapting the process based on feedback.
Ques:- How do you facilitate and ensure effective sprint retrospectives
Right Answer:
To facilitate effective sprint retrospectives, I would:

1. **Set the Stage:** Create a safe and open environment where the team feels comfortable sharing.
2. **Gather Data:** Collect information about what went well, what didn't, and any challenges faced during the sprint.
3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.
Ques:- What is difference insert() and database .insert() ?
Right Answer:
`insert()` is a method used in Apex to insert records into the database, while `database.insert()` is a more flexible method that allows for additional options, such as handling errors and specifying whether to allow partial success.
Comments
Admin Feb 8, 2020

Using insert method we can insert the records but if any error occurs in any record system will throw an error insertion fail and none of the records are inserted.

If we want to execute partially success of bulk insert operation we will use database .insert.

Ques:- List things that can be customized on page layouts?
Right Answer:
1. Fields (add, remove, reorder)
2. Sections (create, rename, reorder)
3. Buttons (add, remove)
4. Related lists (add, remove, reorder)
5. Visualforce pages (embed)
6. Quick actions (add, remove)
7. Record types (assign)
8. Help text (add, modify)

Ques:- How to call java script using Static Resource in Visual Force page?
Right Answer:
To call JavaScript using a Static Resource in a Visualforce page, use the following syntax:

```html
<apex:includeScript value="{!$Resource.YourStaticResourceName}" />
```

Replace `YourStaticResourceName` with the name of your static resource.

Add javascript file in Static Resource setup -> develop -> Static Resources -> Click on ‘New’ -> Name: filename and add file from local desktop and save.

We can use that file as follows in VisualForce page

Ques:- What is App in Salesforce?
Right Answer:
An App in Salesforce is a collection of tabs, objects, and other components that work together to provide specific functionality or features for users, allowing them to perform tasks related to a particular business process or function.
Comments
Admin Feb 8, 2020

An app is a group of tabs that work as a unit to provide functionality. Users can switch between apps using the Force app drop-down menu at the top-right corner of every page.

You can customize existing apps to match the way you work, or build new apps by grouping standard and custom tabs.

Navigation to create app in Sales force: Setup ->Build ->Create->App-> Click on new and create your application according to your requirements.

Ques:- What is a Visualforce Page?
Right Answer:
A Visualforce Page is a custom user interface component in Salesforce that allows developers to create dynamic web pages using a markup language similar to HTML, along with Apex code for server-side logic.
Comments
Admin Feb 8, 2020

Visualforce is the new markup language from salesforce, by using which, we can render the standard styles of salesforce. We can still use HTML here in Visualforce. Each visualforce tag always begins with apex namespace. All the design part can be determined by using Visualforce Markup Language and the business logic can be written in custom controllers associated with the Page.

Ques:- What is rate limiting in APIs and how is it implemented
Right Answer:
Rate limiting in APIs is a technique used to control the number of requests a user can make to an API within a specific time period. It is implemented by setting thresholds (e.g., requests per minute) and using mechanisms like tokens, counters, or IP address tracking to monitor and restrict access when the limit is exceeded.
Ques:- What is the difference between synchronous and asynchronous API calls
Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.
Ques:- What are HTTP methods and how are they used in APIs
Right Answer:
HTTP methods are standardized request types used in APIs to perform actions on resources. The main methods are:

1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.

These methods define the action to be performed on the specified resource in the API.
Ques:- What is CORS and how does it affect API development
Right Answer:
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.
Ques:- What are the different types of APIs
Right Answer:
The different types of APIs are:

1. **Open APIs (Public APIs)** - Available to developers and third parties.
2. **Internal APIs (Private APIs)** - Used within an organization.
3. **Partner APIs** - Shared with specific business partners.
4. **Composite APIs** - Combine multiple endpoints into a single call.
5. **Web APIs** - Accessible over the internet using HTTP/HTTPS.
