which two of the following does the administrator need to verify to resolve this situation?

Refer to the exhibit.

A new Cisco Unified Communications Manager Express system has been deployed and the technician is trying to add the first new IP phone to the system. The phone powers up, but it does not register with the system. The technician has verified that the phone is getting the proper VLAN
information from Cisco Discovery Protocol. The phone is also getting the correct IP address and TFTP server address from DHCP. The phone has been assigned to an ephone and the correct MAC address is configured. With the information provided, which two of the following does the administrator need to verify to resolve this situation? (Choose two.)

A.
Verify that the ip helper-address is correctly configured.

B.
Verify that telephony-service has been configured.

C.
Verify that the ephone has a button assigned.

D.
Verify that the tftp-server path has been configured.

E.
Verify that the Cisco Unified Communications Manager Express service is running.

F.
Verify that the correct phone type files are in the tftp-server path.

Explanation:

Since the phone is getting the correct TFTP address, the next thing that needs to be verified is the TFTP Server path and IP Reachablity for the IP Phone to the TFTP Server. Once the TFTP settings has been verified, check if the files mentioned in the termxx.defaults.loads file is available in the TFTP Server for the phone to download.
