CompTIA Server+ SK0-005 Practice Question
During a renovation, a server administrator must secure a large interior window that gives visitors in the lobby a direct view of the new server room. Technicians still need to watch the lobby through the glass, but auditors require that passers-by cannot see racks, consoles, or screen data. Which physical access control best satisfies these requirements with the least day-to-day upkeep?
Fit the window with switchable electrochromic (smart) glass that turns opaque when unpowered.
Install one-way reflective glass or apply mirror privacy film with the lobby side brightly lit.
Replace the pane with UL-rated bullet-resistant laminated safety glass.
Add low-emissivity tinted glazing that blocks approximately half of visible light.
