Refer to the exhibit. Which option describes the security encryption status of this active call on a Cisco IP phone?
The correct answer is D. encrypted call signaling and media. The question asks to interpret the security encryption status of an active call on a Cisco IP phone based on an implied exhibit, where a padlock icon typically indicates full encryption.

Why each option
The question asks to interpret the security encryption status of an active call on a Cisco IP phone based on an implied exhibit, where a padlock icon typically indicates full encryption.
This would typically be indicated by the absence of security icons or an open lock icon, if present.
This scenario might show a different icon or partial indication; a single padlock usually implies both.
Similar to B, this scenario would likely have a different visual indicator than a single padlock for full encryption.
Cisco IP phones display specific icons to indicate the security status of a call. A padlock icon typically indicates that both the call signaling (via SIP TLS) and the call media (via SRTP) are encrypted, providing end-to-end security for the communication.
In the context of an exam question where an exhibit is explicitly referenced, there is usually sufficient information provided by the exhibit itself, making this choice incorrect.
