• It allows for creativity because of its ad-hoc approach to software development.
• It gives development teams a process to follow to improve efficiency and reduce risks.
• It defines all the roles of the development team.
• It helps technical writers develop accurate documentation.

Explanation: The SDLC provides a framework for streamlining development and minimizing risks.

Question 3)
Which of the following best describes an activity that happens in the maintenance phase of the SDLC?

• The coding process begins.
• Code is thoroughly tested.
• Fixing minor user interface issues.
• The system requirements specification is written.

Explanation: Maintenance involves refining and fixing issues post-deployment.

Question 4)
Which of the following best describes a beta release?

• It is the first functioning version of a system released to a select group of stakeholders.
• It is the most stable release.
• It is intended for all users.
• It meets all functional requirements.

Explanation: A beta release is an early version of software given to a limited audience for testing.

Question 5)
Which statement best describes the Software Requirements Specification (SRS)?

• It can be combined with the System Requirements Specification (SysRS) to form the User Requirements Specification (URS).
• It is combined with the User Requirements Specification (URS) to form the System Requirements Specification (SysRS).
• It primarily contains use cases.
• It contains functional, external interface, and non-functional requirements.

Explanation: The SRS outlines detailed requirements for the system, including functional and non-functional aspects.

Question 6)
Which of the following is an iterative approach to the software development lifecycle (SDLC)?

• Agile
• Verification
• Waterfall
• V-shape

Explanation: Agile is an iterative methodology, focusing on continuous development and feedback.

Question 7)
Which of the following best describes functional testing?

• It is concerned with confirming that a recent change to the application is not adversely affecting existing functionality.
• It tests application attributes like performance and security.
• Its goal is to make sure the application is usable and accessible.
• It tests application attributes like scalability and availability.

Explanation: Functional testing checks if the software meets the specified functional requirements.

Question 8)
Which best describes black-box testing?

• It is used to verify internal structure, design, and coding.
• It is equivalent to regression testing.
• It is equivalent to non-functional testing.
• It is used to test inputs and outputs.

Explanation: Black-box testing focuses on checking the output based on the given input, without knowing the internal code.

Question 9)
