SSCP Practice Question: A security analyst is reviewing the configuration…
A security analyst is reviewing the configuration of an enterprise wireless network. Which TWO of the following are best practices for securing the wireless network against unauthorized access and eavesdropping?
Answer choices
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
✓
Configure a dedicated guest network on a separate VLAN
WPA2-Enterprise with RADIUS provides strong per-user authentication and encryption, mitigating unauthorized access. Placing guest traffic on a separate VLAN segments network traffic and reduces exposure of internal resources. WPA2-PSK with a complex passphrase is acceptable for small networks but not enterprise-grade. Disabling SSID broadcast is not a security control as it can be easily discovered. WPS is known to have severe vulnerabilities and should be disabled.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a dedicated guest network on a separate VLAN
Why this is correct
Isolating guest traffic on a separate VLAN prevents unauthorized access to internal resources and contains potential threats.
- ✗
Activate WPS for simplified client setup
Why it's wrong here
WPS has known vulnerabilities (e.g., PIN brute-force) that easily compromise the network; it should always be disabled.
- ✗
Enable WPA2-PSK with a complex passphrase
Why it's wrong here
WPA2-PSK relies on a shared passphrase, which is susceptible to offline brute-force attacks and is not recommended for enterprise environments due to lack of individual user accountability.
- ✓
Implement WPA2-Enterprise with RADIUS authentication
Why this is correct
WPA2-Enterprise uses 802.1X for per-user authentication via RADIUS, providing strong encryption and identity management.
- ✗
Disable SSID broadcast to hide the network
Why it's wrong here
Disabling SSID broadcast does not provide real security; the SSID can be easily discovered using passive scanning tools, and clients may experience connectivity issues.

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.
