CompTIA A+ Core 2 (220-1102) — Question 563

A technician is configuring security for a computer that is located in a common area. A sign above the computer indicates only authorized users can use the computer. Guests visiting the office must walk past the computer to enter and leave the office. Which of the following will offer the best protection against physical threats?

Answer options

• A. Using screen lock
• B. Installing a privacy screen
• C. Implementing password complexity
• D. Locking the computer case
• E. Enabling drive encryption

Correct answer: D

Explanation

Locking the computer case is the most effective way to protect against physical threats, as it prevents unauthorized access to the internal components and data. The other options, while helpful for securing data and privacy, do not physically prevent someone from accessing the computer itself or tampering with it.
