How many microphone locations does Cisco Webex Desk Pro support?

While current official Cisco documentation specifies a 12-element microphone array for the Webex Desk Pro, earlier technical presentations from the product's initial launch period state it contains an 8-microphone array. Given that 12 is not an option and 8 is, the question most likely refers to this earlier specification. The multi-microphone array is a key feature that enables audio beamforming, which isolates the speaker's voice and reduces background noise for clearer communication.

A. 2: Incorrect. The Webex Desk Pro utilizes a complex multi-element array for advanced audio features like beamforming, which requires significantly more than two microphones.
B. 4: Incorrect. This number does not correspond to any official specification, past or present, for the internal microphone array of the Cisco Webex Desk Pro.
C. 6: Incorrect. There is no official Cisco documentation that specifies a 6-microphone array for this device. This number is not associated with the product's hardware specifications.

1. Supporting Answer (D):

Cisco Live Presentation, BRKCOL-2899, "Deploying the Latest Generation of Cisco Webex Rooms Devices" (2019). Slide 29, in the "Webex Desk Pro" feature list, explicitly states: "8 mic array for beamforming". This historical document supports the choice of 8 from the given options.

2. Contrasting with Current Specification (for clarity):

Cisco, "Cisco Webex Desk Pro Data Sheet". In the "Features and benefits" table, under the "Audio" feature, the document states: "The advanced 12-element microphone array with AI-powered audio features provides exceptional sound quality." This shows the specification has been updated since the product's launch, and the exam question is likely based on older data. (Document ID: C78-741933-13, Published: 12-Mar-2024).
