CompTIA A+ Core 2 (220-1202) — Question 62

A company recently transitioned to a cloud-based productivity suite and wants to secure the environment from external threat actors. Which of the following is the most effective method?

Answer options

• A. Multifactor authentication
• B. Encryption
• C. Backups
• D. Strong passwords

Correct answer: A

Explanation

Multifactor authentication (MFA) is the most effective method because it adds an extra layer of security by requiring users to provide two or more verification factors to gain access. While encryption, backups, and strong passwords are important security measures, they do not provide the same level of protection against unauthorized access as MFA does.
