  2. budget of the project

  3. business scope

  4. All of the above

  5. Only (1) and (2)

Show answer
Correct Option: D
Explanation:

Yes , all determine the feasibility factors.

Which of the following is not a type of feasibility in SDLC (System Development Life Cycle)?

  1. Operational Feasibility

  2. Economic Feasibility

  3. Schedule Feasibility

  4. Legal Feasibility

  5. None of the above

Show answer

Which of the following statement(s) is/are false?

  1. Data Flow Diagram shows the data transfer between the entities in the system.

  2. A DFD shows a lower level view of the system.

  3. DFD is made by a software analyst of designer.

  4. DFD shows the functionality of the system.

  5. None of the above

Show answer
Correct Option: B
Explanation:

This is a false statement as a DFD shows a higher level view of a system as it shows the actual transfer of the data in the system whereas a flow chart shows a lower level view of the system as it shows only the data transfer activities in the system and not the transfer of the data.
