Which of the following is NOT an equipment vulnerability described for retaining classified information in copying equipment?

• A. Paper jams may cause paper with images to be retained in the machine.
• B. Ink on rollers may retain images of classified information.
• C. Extra copies or partial copies may be retained in the machine or discarded via a special port.
• D. Unauthorized remote access to copier controls.

Answer: (D)

The key idea is understanding what kinds of hardware-related vulnerabilities can cause classified material to be left behind inside a copying device. In this context, the machine can physically retain images because of how it processes and handles pages.

Paper jams can leave sheets with classified images inside the copier, so those remnants could be recovered later. Ink on rollers can carry image impressions, meaning parts of the classified content could remain on the rollers after a job. Extra copies or partial copies might stay in internal bins or could be discarded through a special port, creating a direct path for material to be left behind in the machine.

Unauthorized remote access to copier controls, however, is about who can operate or configure the copier remotely. It’s a cybersecurity or access-control concern, not a physical retention issue inside the equipment. It does not describe a way the device itself retains classified information, making it not an equipment vulnerability of the type described for retaining copies in copying equipment.
