MD-102 Manage and maintain devices Practice Question
You are troubleshooting a user's Windows 11 device that cannot connect to the corporate Wi-Fi network. The device is managed by Intune and has a Wi-Fi profile assigned. The profile uses SCEP certificate authentication. The certificate is issued by your internal CA. The device shows 'No internet access' though it connects. What is the most likely issue?
⚠ Common exam trap
The trap here is that candidates see the device connects and assume the profile is correct, overlooking that certificate-based authentication requires both the client certificate and the root CA trust anchor to be present on the device.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The root CA certificate is not deployed to the device
The device connects to the Wi-Fi network but shows 'No internet access,' indicating the SSID and connectivity are functional. With SCEP certificate authentication, the client must trust the issuing CA's root certificate to validate the server-side certificate during the EAP-TLS handshake. If the root CA certificate is not deployed to the device via Intune, the certificate chain cannot be verified, causing the connection to fail at the authentication layer even though the Wi-Fi association succeeds.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The SSID in the profile is incorrect
Why it's wrong here
Would result in connecting to a different network or none.
- ✓
The root CA certificate is not deployed to the device
Why this is correct
Without the root CA, the SCEP certificate cannot be validated.
- ✗
The user does not have an Intune license
Why it's wrong here
Would prevent enrollment, not certificate authentication.
- ✗
The Wi-Fi profile is not assigned to the device
Why it's wrong here
Would prevent the profile from appearing on the device.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
