After you change the IP address of a Cisco TelePresence Codec C90, you are unable to
use Telnet or a browser to connect to that address. However, you are able to use ping to
connect to the new address. What are the two possible causes? (Choose two.)

A.
The codec needs to reboot after the IP address change in order to bind the services to
the new address.

B.
The gatekeeper configuration failed and you need to set up the gatekeeper address and
the discovery type again.

C.
The codec disabled the Telnet and HTTP services after the IP address change.

D.
The configuration failed and there is another device with the same address that responds
to the ping.
