For wireless access points that are authorized, which element must be documented?

• A. The model number
• B. The vendor contact
• C. The last maintenance date
• D. The business justification

Answer: (D)

The essential idea is that every authorized wireless device needs a clear, documented reason for its existence. Documenting the business justification shows why the access point is needed, what business problem it solves, and how the risk is being accepted or mitigated by management. This keeps deployments accountable, supports change control, and helps prevent unmanaged or rogue devices from being added later.

While details like the model number, vendor contact, or last maintenance date are useful for inventory and maintenance records, they do not by themselves justify the deployment or address the risk management aspect. They aid in administration, but the justification demonstrates the business need and approved rationale for the device's presence in the network.
