300-070 Question #51: Real Exam Question with Answer & Explanation

The correct answer is A: direct mode. The Cisco TelePresence MCU MSE 8510 supports four H.323 gatekeeper registration modes: (A) Direct mode - the MCU registers with the gatekeeper, but call signaling goes directly between endpoints without traversing the gatekeeper. (B) H.225-routed mode - the gatekeeper routes the

Question

Which four modes are available on the Cisco TelePresence MCU MSE 8510 to connect to a gatekeeper? (Choose four.)

Options

Adirect mode
BH.225-routed mode
CH.265-routed mode
DH.245-routed mode
Efull proxy mode
Fpartial proxy mode

Explanation

The Cisco TelePresence MCU MSE 8510 supports four H.323 gatekeeper registration modes: (A) Direct mode - the MCU registers with the gatekeeper, but call signaling goes directly between endpoints without traversing the gatekeeper. (B) H.225-routed mode - the gatekeeper routes the H.225 call setup signaling but H.245 (capability/media negotiation) goes direct. (D) H.245-routed mode - both H.225 and H.245 signaling are routed through the gatekeeper. (E) Full proxy mode - all signaling and media are proxied through the gatekeeper. Option C (H.265-routed) does not exist as a gatekeeper mode; H.265 is a video codec, not a signaling protocol. Option F (partial proxy) is not a standard defined mode for this device.
