An engineer needs to prepare a room for a Cisco TelePresence Immersive System installation. Which two recommendations should the engineer follow? (Choose two.)

Acoustic wall panels are actually recommended in TelePresence room design to control reverberation and echo, improving overall audio quality.

Plants and minor decorations are not specifically prohibited by Cisco TelePresence room guidelines; the primary design concerns are color, contrast, lighting, and acoustics.

Glossy finishes are discouraged because they create reflections and glare that interfere with camera imaging and disrupt lighting uniformity across the room.

Avoiding high-contrast elements is recommended because sharp visual contrasts can cause the camera's auto-exposure to struggle, creating distracting visual artifacts that degrade the immersive experience. The room should present a visually calm, uniform environment so the system can maintain consistent image quality.

Earth tone paint colors provide a neutral, camera-friendly background that does not skew white balance or color reproduction. Cisco TelePresence guidelines specifically recommend muted, earth-toned colors to ensure accurate skin tone rendering and a professional visual environment.
