The answer is WPA3-Enterprise with 192-bit encryption. This protocol is the correct choice because it mandates individual authentication via 802.1X, allowing each student to log in with unique credentials on a single SSID, while the 192-bit cryptographic suite provides the strongest available protection against brute-force and dictionary attacks—critical for a high-density school environment. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding that WPA3-Enterprise is the only option that combines scalable, per-user authentication with government-grade encryption, and a common trap is selecting WPA2-Enterprise, which lacks the same resilience against offline password guessing. Remember the mnemonic “3 for 3”: WPA3-Enterprise with 192-bit encryption gives you three layers of security—individual logins, stronger encryption, and attack resistance.
220-1202 Wireless Security Protocols Practice Question
This 220-1202 practice question tests your understanding of wireless security protocols. 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 technician is configuring a new wireless network for a school. The network must support hundreds of student devices simultaneously and provide strong security. The school wants to use a single SSID with individual logins for students. Which security protocol should the technician choose?
Why wrong: Incorrect. WPA2-PSK uses a shared key, not individual logins, and is less secure for large deployments.
B
WPA2-Enterprise with 802.1X and RADIUS.
Why wrong: Incorrect. While WPA2-Enterprise supports individual logins, WPA3-Enterprise offers better security and is recommended for new deployments.
C
WPA3-Enterprise with 192-bit encryption.
Correct. WPA3-Enterprise provides individual authentication via 802.1X and uses 192-bit encryption, meeting the school's needs for security and scalability.
D
WPA3-Personal with SAE.
Why wrong: Incorrect. WPA3-Personal uses a shared passphrase, not individual logins, so it does not meet the requirement for per-user authentication.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
WPA3-Enterprise with 192-bit encryption.
WPA3-Enterprise with 192-bit encryption is the most secure option for environments requiring individual authentication and high traffic. It provides stronger encryption and protection against dictionary attacks compared to WPA2-Enterprise.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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-PSK with a long passphrase.
Why it's wrong here
Incorrect. WPA2-PSK uses a shared key, not individual logins, and is less secure for large deployments.
✗
WPA2-Enterprise with 802.1X and RADIUS.
Why it's wrong here
Incorrect. While WPA2-Enterprise supports individual logins, WPA3-Enterprise offers better security and is recommended for new deployments.
✓
WPA3-Enterprise with 192-bit encryption.
Why this is correct
Correct. WPA3-Enterprise provides individual authentication via 802.1X and uses 192-bit encryption, meeting the school's needs for security and scalability.
Related concept
Authentication checks who the user is.
✗
WPA3-Personal with SAE.
Why it's wrong here
Incorrect. WPA3-Personal uses a shared passphrase, not individual logins, so it does not meet the requirement for per-user authentication.
Common exam traps
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.
Trap categories for this question
Keyword trap
Incorrect. WPA3-Personal uses a shared passphrase, not individual logins, so it does not meet the requirement for per-user authentication.
Detailed technical explanation
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.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
