• Question 131:

  A company is moving forward with a new product. Product scope has been determined, teams have formed, and backlogs have been created. Developers are actively writing code for the new product, with one team concentrating on delivering data via REST services, one Team working on the mobile apps, and a third team writing the web application. Which phase of the software development lifecycle (SDLC) is being described?

  A. Deployment
  B. Design
  C. Implementation
  D. Requirements
  C. Implementation

  ---

  The phase being described is the.Implementation.phase of the SDLC. During this phase, the actual development starts, and the product begins to be built. The teams are actively writing code, which is a key activity of the Implementation phase. This phase involves translating the design and specifications into executable code, developing the software's features, and then integrating the various components into a full-fledged system.

• Question 132:

  What refers to the review of software source code by developers other than the original coders to try to identify oversights, mistakes, assumptions, a lack of knowledge, or even experience?

  A. User acceptance testing
  B. Manual peer review
  C. Fault injection
  D. Dynamic code review
  B. Manual peer review

  ---

  Manual peer review refers to the systematic examination of software source code by developers other than the original author. This practice is recognized as a valuable tool for reducing software defects and improving the quality of software projects. It involves developers inspecting the code to find and fix mistakes overlooked in the initial development phase, which enhances both the overall quality of software and the developers' skills.

  Peer code review is less formal and more "lightweight" than the code inspections performed in the past, and it provides benefits such as knowledge transfer, increased team awareness, and creation of alternative solutions to problems.

• Question 133:

  During threat modeling, the team assigns numerical values based on damage potential and exploitability. Which step of threat modeling is this?

  A. Identify assets
  B. Rate threats
  C. Define scope
  D. Document mitigations
  B. Rate threats

  ---

  Rating threats involves assigning scores based on factors such as impact and likelihood. This step helps prioritize risks so mitigation efforts focus on the most serious threats.
