350-401 Practice Question: The default CAPWAP control path DTLS encryption…
What is the default CAPWAP control path DTLS encryption mode on Cisco 9800 WLCs?
⚠ Common exam trap
Cisco often tests the distinction between control path and data path DTLS defaults, where candidates mistakenly think DTLS is optional or disabled by default, or confuse the default for data path (disabled) with control path (enabled).

Correct answer & explanation
✓
Enabled
Cisco 9800 WLCs have CAPWAP control path DTLS encryption enabled by default to secure control plane communications between the WLC and APs. This is mandated by RFC 5415 and ensures integrity and confidentiality of management traffic such as configuration and keepalives. The default setting cannot be disabled globally; it is always active for control traffic.
