CompTIA A+ Core 2 (220-1102) — Question 194

A network technician installed a SOHO router for a home office user. The user has read reports about home routers being targeted by malicious actors and then used in DDoS attacks. Which of the following can the technician MOST likely do to defend against this threat?

Answer options

• A. Add network content filtering.
• B. Disable the SSID broadcast.
• C. Configure port forwarding.
• D. Change the default credentials.

Correct answer: D

Explanation

Changing the default credentials is crucial because many attackers exploit default usernames and passwords to gain unauthorized access to routers. The other options, while beneficial for network security, do not directly address the vulnerability posed by default credentials and may not prevent unauthorized access as effectively.
