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.

An auxiliary alarm system uses a direct connection (usually via leased lines) to a public emergency service center, such as police, fire, or 911. This provides rapid response but limits control to only the responding agencies, unlike proprietary or central station systems.

Comprehensive Detailed Explanation:
The American Bus Association's Action Plan for enhancing bus security primarily focuses on:
Increasing vigilance and training among operators (A),
Protecting transportation infrastructure (D),
Preserving the industry as a national transportation asset (C).
While infrastructure is an important topic, assisting in its development is not explicitly a stated goal of the ABA security action plan. The main thrust is operational safety and emergency preparedness, not structural development.

Metal halide lamps emit a bright, white light with a bluish cast. This makes them ideal for applications requiring good color rendering and visibility, such as CCTV surveillance or high-intensity outdoor lighting.
A (Sodium vapor) emits yellow/orange light.
C (Mercury vapor) also has a bluish tint but less desirable color rendering.
D (Incandescent) gives off a warm, yellowish light.

After a risk assessment is completed, the first step for a project manager is to create a concept design. This outlines the proposed system and supports budget justification and strategic alignment with management's objectives. Gaining senior management buy-in is essential before progressing to detailed design or procurement.
A (RFI) may follow concept approval.
C (Construction documents) are created much later.
D (Implementation planning) is dependent on approved design and funding.
