The answer is WPA3-Enterprise, the correct wireless security standard for a deployment requiring the highest level of client authentication with a RADIUS server. This standard mandates 802.1X/EAP authentication via a RADIUS server and enforces the 192-bit Commercial National Security Algorithm (CNSA) Suite, replacing the vulnerable four-way handshake with the Simultaneous Authentication of Equals (SAE) handshake for stronger key exchange. On the CompTIA Network+ N10-009 exam, this question tests your ability to distinguish WPA3-Enterprise from WPA2-Enterprise or WPA3-Personal; a common trap is assuming WPA3-Personal, which uses SAE but lacks RADIUS and the 192-bit suite, meets the “highest security” requirement. Remember the key differentiator: WPA3-Enterprise is the only standard that combines RADIUS integration with mandatory 192-bit encryption. A useful memory tip is to think “Enterprise = RADIUS + 192-bit CNSA” for the top-tier security on the exam.
N10-009 Network Security Practice Question
This N10-009 practice question tests your understanding of network security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
WPA3-Enterprise
WPA3-Enterprise (option B) is correct because it mandates the use of a RADIUS server for 802.1X/EAP authentication and provides the highest level of wireless security, including 192-bit minimum-strength security suite (CNSA Suite) and SAE handshake replacement for the 4-way handshake. This meets the requirement for both RADIUS integration and maximum authentication security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
WPA2-Personal
Why it's wrong here
WPA2-Personal uses a pre-shared key (PSK) and does not involve a RADIUS server. It is less secure than enterprise versions.
✓
WPA3-Enterprise
Why this is correct
WPA3-Enterprise provides the highest security with 192-bit encryption and requires a RADIUS server for authentication, meeting the requirement.

Read the scenario before looking for a memorised answer.
✗
WPA2-Enterprise
Why it's wrong here
WPA2-Enterprise uses RADIUS and is secure, but WPA3-Enterprise is the current gold standard and offers better protections.
✗
WPA3-Personal
Why it's wrong here
WPA3-Personal uses SAE but still relies on a shared password, not a RADIUS server, so it does not meet the requirement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between WPA2-Enterprise and WPA3-Enterprise, where candidates mistakenly choose WPA2-Enterprise because it also uses RADIUS, overlooking that WPA3-Enterprise provides superior security with SAE and mandatory 192-bit encryption.
Detailed technical explanation
How to think about this question
WPA3-Enterprise introduces the Simultaneous Authentication of Equals (SAE) handshake, which replaces the 4-way handshake used in WPA2-Enterprise, providing resistance to offline dictionary attacks and offering forward secrecy. It also mandates the use of a RADIUS server with 802.1X/EAP, and for the highest security mode (192-bit), it requires the Commercial National Security Algorithm (CNSA) Suite, including AES-256-GCM, HMAC-SHA384, and ECDHE key exchange. In a real-world scenario, a government agency or financial institution would deploy WPA3-Enterprise to protect against advanced threats like KRACK attacks that exploit WPA2 vulnerabilities.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
