Federal IT Security Professional (FITSP) Operator Practice Test

Understanding how this SDLC is described helps you see what counts as a distinct stage. In this description, the stages listed are Initiation, Acquisition/Development, and Disposition. Testing, while essential, isn’t treated as its own separate phase here; it’s typically carried out as part of development or QA activities within the acquisition/development work, rather than as a standalone phase. Therefore, Testing is not listed as a separate phase in this SDLC description, making it the correct choice. The other options fit as clearly named phases: Initiation marks the project start, Acquisition/Development covers building or procuring the system, and Disposition handles decommissioning at the end of the lifecycle.
