Which two methods are used to navigate the menu options of an auto attendant on an MCU? (Choose two.)

KPML (Key Press Markup Language) is a SIP-based protocol used to report DTMF digit events between SIP entities and is not a user-facing navigation method for an MCU auto attendant.

DTMF (Dual Tone Multi-Frequency) tones generated by pressing keypad digits are the standard method for selecting options in an MCU auto attendant menu, functioning similarly to IVR navigation on a phone system.

PiP (Picture in Picture) is a video layout feature that controls how participant video streams are displayed on screen, and has no function in navigating menu systems.

PoP is not a recognized Cisco conferencing protocol or navigation mechanism relevant to MCU auto attendant menus.

FECC (Far End Camera Control) commands transmitted from a video endpoint are interpreted by the Cisco MCU as directional navigation inputs, allowing users to scroll through and select auto attendant menu options without using a telephone keypad.

SCCP (Skinny Client Control Protocol) is a proprietary Cisco signaling protocol used between IP phones and Cisco Unified Communications Manager, not a method for navigating MCU auto attendant menus.
