X.25 is a standard protocol suite developed by the Consultative Committee for International Telephone and Telegraph (CCITT), now known as ITU-T. It is one of the earliest protocols used for WAN communications, enabling reliable data transfer across public networks using packet switching.
XA.10 (B), CXA 1.23 (C), and X.20 (D) are not recognized standards for WAN protocols.

Insurance should be viewed as a complementary component of a security program, not a replacement. It provides financial recovery after a loss has occurred but does not prevent the loss itself. Security operations- including physical barriers, surveillance, policies, and personnel-serve as the primary defense against threats. Insurance mitigates the financial impact only after an incident.

Preliminary cost estimates are developed during the feasibility phase of a project. These early estimates help determine whether a project is viable and worth pursuing, guiding initial decision-making and budgeting discussions.
A (Design) and B (Development) phases involve more detailed cost estimates.
C (Execution) is when implementation begins, after funding is approved.

Strict liability applies when a manufacturer or service provider is held legally responsible for damages or injuries caused by a defective product or service, regardless of fault or intent. This type of liability is often associated with consumer protection laws, where the focus is on the danger posed to the user rather than negligence on the part of the provider.
Plaintiff (B) is the party bringing the suit.
Defendant (C) is the party being sued.
"None of the above" (D) is incorrect since "Strict liability" is the correct legal principle.
