CND Practice Question: Enterprise Cloud Virtual And Wireless Network Protection
A network engineer is configuring an enterprise wireless network and wants to prevent clients from connecting to unauthorized rogue access points that broadcast the corporate SSID. Which client-side and infrastructure technology should be deployed?
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
✓
Protected Management Frames (PMF / 802.11w)
802.11r (Fast BSS Transition) along with WIPS and 802.1X authentication helps secure connections, but specific rogue AP countermeasures involve infrastructure-generated deauthentication frames and client protection profiles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Static WEP encryption keys
Why it's wrong here
WEP is insecure and easily cracked.
- ✗
MAC address filtering on access points
Why it's wrong here
MAC addresses are easily spoofed in wireless traffic and provide no real security against determined attackers.
- ✓
Protected Management Frames (PMF / 802.11w)
Why this is correct
PMF (802.11w) protects wireless management frames such as deauthentication and disassociation frames against spoofing and rogue attacks.
- ✗
Disabling SSID broadcast (closed network)
Why it's wrong here
Hiding SSID broadcasts does not prevent rogue AP attacks because SSIDs are revealed in probe requests and responses.
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.
