Explanation:
Certification and accreditation (C&A) processes are performed before a system can be formally installed in the production environment. Certification is the technical testing and evaluation of a system while accreditation is the formal authorization given by management to allow a system to operate in a specific environment. The accreditation decision is based upon the results of the certification process. This occurs during the acceptance phase.
Incorrect Answers:
A: The project initiation and planning phase is the initial phase that establishes the need for a system.
Nothing has been developed yet to be evaluated, tested, accredited, etc.
B: System requirement specifications are gathered in the system design and specifications phase. This phase determines how the system will accomplish design goals and could cover required functionality, compatibility, fault tolerance, extensibility, security, usability, and maintainability.
C: During the development & documentation phase programmers are assigned tasks to meet the specifications laid out in the design phase. This is where the system is developed.

When using packet switching, messages are broken down into packets. Source and destination address are added to each packet so that when passing through a network node, they can be examined and eventually rerouted through different paths as conditions change. All message packets may travel different paths and not arrive in the same order as sent. Packets need to be collected and reassembled into the original message at destination.
