210-065 Question #47: Real Exam Question with Answer & Explanation
The correct answer is B: The codec and the Touch 8 are on separate subnets.. Auto-discovery of a codec by a Touch 8 panel relies on multicast communication within the same subnet and requires pairing visibility to be enabled on the codec.
Question
A technician is trying to pair a Touch 8 with a Cisco TelePresence SX20 endpoint, but the codec is not automatically listed in the touch panel. What are two possible reasons for this behavior? (Choose two.)
Options
- AThe codec firmware version is below version TC 6.1.
- BThe codec and the Touch 8 are on separate subnets.
- CPairing visibility mode is not active on the codec.
- DThe codec is not compatible with a Touch 8 device.
- EThe Touch 8 is connected via the second Ethernet port on the codec.
Explanation
Auto-discovery of a codec by a Touch 8 panel relies on multicast communication within the same subnet and requires pairing visibility to be enabled on the codec.
Common mistakes.
- A. While Touch 8 requires a minimum firmware version, the relevant threshold is TC 7.x or later, not TC 6.1; TC 6.1 is not the boundary version for Touch 8 compatibility.
- D. The Cisco TelePresence SX20 is a supported and compatible codec for use with the Touch 8 control panel.
- E. The Touch 8 connects via the dedicated touch panel port or the primary LAN port on the codec, and connection via the second Ethernet port is not a documented reason for auto-discovery failure.
