CompTIA A+ Core 2 (220-1202) — Question 130

A technician needs to download and install a new web browser on a desktop computer. Which of the following should the technician use to verify the installer is an authentic version?

Answer options

• A. Date
• B. Hash
• C. Size
• D. Name

Correct answer: B

Explanation

Using a hash allows the technician to verify the integrity of the downloaded file by comparing it to a known good value, ensuring it hasn't been tampered with. The other options, such as date, size, and name, do not provide a reliable method for confirming the authenticity of the installer.
