Q8 Single choice

A technical support team is deploying a new Cisco Desk Pro endpoint for a user. The device has been physically connected to the network, received an IP address, and can successfully ping general internet websites. However, when attempting to activate the device using the activation code from Webex Control Hub, the Desk Pro shows a Registration Failed message, and its status in Control Hub remains Unregistered.

What is the cause of the registration failure?

A
The 24-hour window of the Activation code has passed, after which the code returns invalid_error.
B
The endpoint's system time is significantly out of sync with Network Time Protocol servers.
C
A room OS device can be added only using its MAC address. The activation code from Control Hub ends up in failed registration.
D
The organization's firewall or proxy server is blocking specific ports or URLs required for Webex Cloud service communication.
