Certified Network Defender (CND) — Question 77

Which of the following is the best way of protecting important data against virus attack?

Answer options

• A. Implementing a firewall.
• B. Updating the anti-virus software regularly.
• C. Taking daily backup of data.
• D. Using strong passwords to log on to the network.

Correct answer: B

Explanation

Updating the anti-virus software regularly ensures that the latest virus definitions and security patches are applied, providing the best protection against new and evolving threats. While implementing a firewall, taking backups, and using strong passwords are important security measures, they do not specifically target virus protection as effectively as keeping anti-virus software up to date.
