Unintentional access to software code is referred to as:
Correct Answer: B
A trapdoor (also known as a backdoor) is a hidden method used by developers or attackers to bypass normal authentication or access controls in software. However, in technical distinction, a "trapdoor" refers more to unintentional or overlooked access, while "backdoor" is often intentional. For this question, since it emphasizes "unintentional access," trapdoor is the best fit. Bomb (A): Refers to logic bombs-malicious code triggered by specific conditions. Backdoor (C): Usually intentionally left in place by developers or attackers. Trojan Horse (D): Malware disguised as legitimate software.

Question 17
A change review board generally consists of:
Correct Answer: B
A Change Review Board (CRB) is typically composed of key stakeholders representing the major interests involved in a project-engineering, operations, security, IT, procurement, and other relevant departments. This cross-functional group ensures that proposed changes are reviewed, justified, and approved collaboratively. A, C, and D list some roles, but they don't fully represent the project's key partners in a typical governance model.

Question 18
A guiding principle of business continuity planning is that the plan:
Correct Answer: B
A guiding principle of business continuity planning is flexibility. While the plan provides structure and direction, every crisis is unique and may require adjustments. A rigid plan may fail if it doesn't account for variables in real-time conditions, making adaptability a critical success factor. A (remote site capability) may be included, but it is not a universal requirement. C is unrealistic-it's not feasible to have complete instructions for every possible scenario. D (outline format) is too minimalistic and reactive rather than proactive.

Question 19
LANs and WANs can communicate with each other using a communications rule called:
Correct Answer: A
Question 20
Who developed Ethernet?
Correct Answer: A
Ethernet was developed in the early 1970s by Robert Metcalfe and his team at Xerox Corporation's Palo Alto Research Center (PARC). It became the foundational technology for local area networks (LANs) and remains widely used in networking today. IBM (B) developed other networking technologies but not Ethernet. Microsoft (C) is a software company and did not develop Ethernet. References: PSP Study Guide - Network Communication Protocols Historical Overview of Ethernet - IEEE Standard
