CompTIA Network+ (N10-007) — Question 146

A technician is making the population of routers more secure. Which of the following are the BEST options for making authentication more secure? (Choose two.)

Answer options

• A. Add a login banner.
• B. Disable unused services.
• C. Upgrade the firmware.
• D. Disable Telnet.
• E. Implement AAA.
• F. Disable SSH.

Correct answer: D, E

Explanation

Disabling Telnet (D) enhances security by preventing unencrypted remote access, while implementing AAA (E) provides a comprehensive framework for authentication, authorization, and accounting. The other options, while beneficial for overall security, do not directly address the authentication process as effectively as D and E.
