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 configuration failed and there is another device with the same address that responds to the ping.
- B: The codec disabled the Telnet and HTTP services after the IP address change.
- C: The codec needs to reboot after the IP address change in order to bind the services to the new address.
- D: The gatekeeper configuration failed and you need to set up the gatekeeper address and the discovery type again.
