An administrator installed a Cisco Unified IP 8831 Conference Phone that is failing to register. Which two actions are taken to troubleshoot the problem? (Choose two)

HSRP (Hot Standby Router Protocol) provides gateway redundancy and is generally beneficial for network availability; disabling it is unlikely to resolve a phone registration issue.

If the switch port to which the phone is connected is disabled, the phone will not receive network connectivity or Power over Ethernet (PoE) if applicable, preventing it from communicating with the network and registering with Cisco UCM.

RJ-65 is not a standard Ethernet cable type; Cisco IP phones use RJ-45 Ethernet cables for network connectivity.

An RJ-11 cable is typically used for analog phone lines and is not used for network connectivity of a Cisco Unified IP Phone; the PC port on the phone is used to connect a computer, not for the phone's primary network connection.

Cisco IP Phones obtain their configuration, including UCM registration information, from a TFTP server, and DHCP Option 150 provides the IP address of this server, so verifying network access to it is crucial for successful registration.
