Which four fields are required when manually configuring IP phones in Cisco Unified Communications Manager? (Choose four.)

The MAC Address uniquely identifies the physical IP phone and is required so CUCM can match the stored configuration to the correct device when it registers.

IP phones obtain their IP address dynamically via DHCP and the TFTP provisioning process; a static IP is not entered as a field in the CUCM Administration phone configuration page.

Hunt Group is an optional line feature configuration applied after a phone is created and is not a required field during initial phone provisioning.

Voice VLAN ID is configured on the network access switch port and is not a field entered within the CUCM phone configuration interface.

The Device Pool groups common settings such as date/time group, region, and call routing class of service, and must be assigned to every phone at the time of configuration.

The Phone Button Template defines which physical buttons on the phone are assigned as lines, speed dials, or feature buttons, and is a required field for any phone record.

Dial Peer is an IOS-based voice gateway configuration construct used in Cisco IOS routers and does not exist as a field in CUCM phone configuration.

The Device Security Profile specifies the security mode (non-secure, authenticated, or encrypted) for the phone and is a mandatory field in CUCM phone configuration.
