A company is deploying a wireless network that requires the highest level of security for client authentication. The network must use a RADIUS server. Which wireless security standard should be implemented?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
WPA2-Personal
WPA2-Personal uses a pre-shared key (PSK) and does not involve a RADIUS server. It is less secure than enterprise versions.
B
Best answer
WPA3-Enterprise
WPA3-Enterprise provides the highest security with 192-bit encryption and requires a RADIUS server for authentication, meeting the requirement.
C
Distractor review
WPA2-Enterprise
WPA2-Enterprise uses RADIUS and is secure, but WPA3-Enterprise is the current gold standard and offers better protections.
D
Distractor review
WPA3-Personal
WPA3-Personal uses SAE but still relies on a shared password, not a RADIUS server, so it does not meet the requirement.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this N10-009 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: WPA3-Enterprise — WPA3-Enterprise is the most secure wireless authentication standard for enterprise environments. It uses SAE (Simultaneous Authentication of Equals) for authentication and requires a RADIUS server for centralized authentication. WPA2-Enterprise is also secure but has known vulnerabilities (e.g., KRACK). WPA2-Personal and WPA3-Personal use pre-shared keys, not RADIUS servers.
