Right Answer: The different phases in the Solaris boot process are:
1. **Firmware Phase**: Initializes hardware and performs POST (Power-On Self Test).
2. **Boot Loader Phase**: Loads the boot loader (GRUB) from the boot device.
3. **Kernel Phase**: Loads the Solaris kernel into memory and initializes it.
4. **Init Phase**: The init process starts, which sets up system processes and services.
5. **Run Level Phase**: The system enters the default run level, starting user services and login prompts.

Right Answer: Coverage refers to the measurement of how much of the software or system is tested by a set of test cases. Different types of coverage techniques include:
1. **Code Coverage**: Measures the percentage of code executed during testing.
- **Statement Coverage**: Ensures each statement in the code is executed.
- **Branch Coverage**: Ensures each branch (true/false) in control structures is executed.
- **Function Coverage**: Ensures each function or method is called.
2. **Requirement Coverage**: Ensures all specified requirements are tested.
3. **Test Case Coverage**: Measures the extent to which test cases cover the requirements or code.
4. **Path Coverage**: Ensures all possible paths through the code are tested.
5. **Condition Coverage**: Ensures all boolean expressions evaluate to both true and false.
Right Answer: Black box testing is a software testing method where the tester evaluates the functionality of an application without knowing its internal code or structure. The focus is on input and output, ensuring the software behaves as expected based on requirements.
Right Answer: Data-driven testing is a testing methodology where test scripts are executed multiple times with different sets of input data. This approach allows testers to validate the application's behavior under various conditions by using external data sources, such as spreadsheets or databases, to supply the input values.
Right Answer: Functional testing is a type of software testing that verifies if the software functions according to specified requirements. It focuses on testing the application's features and functionalities by providing appropriate input and checking the output against the expected results.
Right Answer: Neutral protection in a transformer refers to the safety measures implemented to protect the transformer from faults that occur in the neutral point of the system. It typically involves using protective relays to detect ground faults or imbalances in the system, ensuring that any issues are quickly isolated to prevent damage to the transformer and maintain system stability.
Right Answer: XHTML Modularization is a framework that allows for the creation of custom XHTML document types by combining different modules, enabling flexibility and reusability in web development.
Right Answer: Check if the CSS file is linked correctly in the HTML, ensure there are no syntax errors in the CSS, verify that the styles are not being overridden by other styles, and make sure the elements have the correct class names applied.
Right Answer: XHTML stands for Extensible Hypertext Markup Language. It is stricter than HTML in terms of syntax and follows XML rules. XHTML was developed by the World Wide Web Consortium (W3C).
Right Answer: In CSS, a class is defined with a dot (.) and can be applied to multiple elements, while an ID is defined with a hash (#) and should be unique to a single element on a page.
Right Answer: The box model in CSS describes the rectangular boxes generated for elements in a document tree and consists of four areas: content, padding, border, and margin. The content is the innermost area, surrounded by padding, then the border, and finally the margin, which is the outermost area.
Right Answer: Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.
Right Answer: `var` is function-scoped or globally-scoped and can be re-declared and updated. `let` is block-scoped, can be updated but not re-declared in the same scope. `const` is also block-scoped, cannot be updated or re-declared, and must be initialized at the time of declaration.
