Right Answer:
A milestone is a significant point or event in a project that marks the completion of a key phase or deliverable.

Right Answer:
**Difference between PLC and SCADA:**
- **PLC (Programmable Logic Controller):** A hardware device used for automation of industrial processes, controlling machinery on factory floors.
- **SCADA (Supervisory Control and Data Acquisition):** A software system that monitors and controls industrial processes at a higher level, providing data visualization and management.

**Merits of PLCs:**
- High reliability and durability.
- Real-time control and fast response times.
- Easy to program and modify.
- Suitable for complex control tasks.

**De-merits of PLCs:**
- Limited data handling and visualization capabilities.
- Higher initial cost for complex systems.
- Requires specialized knowledge for programming.

**Merits of SCADAs:**
- Centralized monitoring and control of multiple PLCs.
- Advanced data visualization and reporting capabilities.
- Remote access and control.
- Scalability for large systems.

**De-merits of SCADAs:**
- Higher complexity and cost.
- Vulnerability to cybersecurity

Right Answer:
Scope management involves defining, controlling, and managing all the work required to complete a project successfully. This includes identifying project requirements, documenting them, and ensuring that all necessary tasks are included while preventing scope creep.

Right Answer:
The critical path in a schedule network diagram is the longest sequence of dependent tasks that determines the shortest time to complete a project. Any delay in the tasks on the critical path will directly impact the project's overall completion time.

Right Answer:
A procurement administrator is responsible for managing the purchasing process, which includes sourcing suppliers, negotiating contracts, processing purchase orders, maintaining inventory levels, and ensuring compliance with procurement policies.

3. Improves product quality through collaborative review.
4. Encourages knowledge sharing and team learning.
5. Provides a structured approach to feedback.
6. Increases accountability among team members.
7. Helps in maintaining project timelines and budgets.
8. Facilitates better understanding of requirements.
9. Supports continuous improvement in processes.
10. Builds team cohesion and morale.

Right Answer:
Quality Assurance (QA) is a systematic process to ensure that products and services meet specified requirements and standards, focusing on preventing defects and improving processes to enhance overall quality.

Right Answer:
The most important allies of Software Quality Assurance (SQA) within an organization are developers, project managers, product owners, and business analysts.

Right Answer:
Alfresco Process Services (APS), formerly Activiti, is a Business Process Management (BPM) engine. It allows you to design, automate, and manage business processes using BPMN 2.0. APS is used to model workflows, execute them, and monitor their progress, enabling organizations to streamline operations and improve efficiency.

Right Answer:
A lookup file is a static reference file used to retrieve additional information based on a key value during data processing. It is typically smaller and used for quick lookups. A join, on the other hand, combines two or more datasets based on a common key, merging their records into a single output. The key difference is that a lookup file is used for referencing data, while a join is used for combining datasets.

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.

Right Answer:
To debug ARM compiled code using tools like Keil or GDB, follow these steps:

1. **Compile with Debug Information**: Ensure your code is compiled with debug symbols enabled (use the `-g` flag for GCC or the appropriate setting in Keil).

2. **Load the Program**: Use Keil's uVision or GDB to load the compiled binary onto the target device or simulator.

3. **Set Breakpoints**: In Keil, set breakpoints using the GUI. In GDB, use the command `break <function_name>` or `break <line_number>`.

4. **Run the Program**: Start the execution of your program. In Keil, click the "Run" button; in GDB, use the command `run`.

5. **Step Through Code**: Use step commands to execute your code line by line (`step` or `next` in GDB).

6. **Inspect Variables**: Check variable values and memory

Right Answer:
The AEM Dispatcher is a caching and load balancing tool for Adobe Experience Manager (AEM) that helps improve performance and scalability. To configure it for caching and load balancing, you need to:

1. **Install the Dispatcher module** on your web server (e.g., Apache or IIS).
2. **Set up the dispatcher configuration file** (dispatcher.any) to define caching rules, such as which content to cache and for how long.
3. **Configure the cache** by specifying the paths to cache and the rules for invalidation.
4. **Set up load balancing** by defining multiple AEM instances in the configuration, allowing the dispatcher to distribute requests among them.
5. **Enable and configure the filters** to control which requests are cached and which are forwarded to AEM.

After making these configurations, restart the web server to apply the changes.

Right Answer:
Telecommunications is the transmission of information over distances using electronic means, such as phones, internet, and satellite systems. It is important because it enables communication, facilitates business operations, connects people globally, and supports the exchange of information in various sectors like education, healthcare, and emergency services.

Right Answer:
Circuit-switched networks establish a dedicated communication path between two endpoints for the duration of the call, while packet-switched networks divide data into packets that are sent independently over shared networks, allowing multiple communications to occur simultaneously without a dedicated path.
