A conference-center operator says, "When I select a different source, the screen needs to settle within two seconds, even when every room is busy." The proposed specification instead limits IP packet transit time. Which replacement measurement captures the operator's requirement?
Correct answer: C - Time from the route command to a stable picture on the display under peak load.
A switch must power eight IEEE Class 4 cameras and four Class 3 control panels after either power supply fails. It reserves the full class allocation at the power-sourcing equipment (PSE), not the devices' measured consumption. Every port supports its connected device. The available PoE budget is 700 W with both supplies and 350 W with one; these budgets already exclude the switch's own consumption. With no other powered loads or additional reserve requirement, which assessment is correct?
Correct answer: C - 301.6 W is required; the one-supply budget is sufficient.
A video appliance sends one continuous UDP flow at 1.35 Gb/s on the wire. Its own network connection supports 10 Gb/s, but the inter-switch path is a two-member 1 Gb/s LACP aggregation using per-flow hashing. Both members are active and otherwise idle. Packet loss persists while one member is saturated and the other carries almost no traffic. Which redesign removes this bottleneck without changing the stream?
Correct answer: B - Replace the aggregation with a supported 10 Gb/s inter-switch link.
A shared switch carries Dante hardware endpoints and office traffic. Packet captures confirm DSCP 56 on time-critical PTP events and DSCP 46 on audio. During file transfers, clock errors occur. Inspection shows that the switch preserves these markings but places all traffic in one first-in, first-out egress queue. The admitted Dante traffic fits within the link capacity. What change would make the intended QoS policy effective?
Correct answer: D - Map trusted DSCP 56 to the highest-priority queue and DSCP 46 to the next queue.
The address plan for one AV VLAN must accommodate 48 AV endpoints, six infrastructure interfaces including the gateway, and 18 reserved addresses for planned AV expansion. Each requires one unique unicast IPv4 address in that VLAN. The network and broadcast addresses cannot be assigned to devices. Which is the smallest subnet that satisfies the plan?
Correct answer: B - /25 - 255.255.255.128
Video starts normally on every receiver, then freezes several minutes later. All devices share one VLAN on an IGMP-snooping switch configured to drop multicast that has no learned membership. An eight-minute capture shows the initial membership reports but no IGMP queries; the relevant forwarding entries disappear when playback stops. The receivers remain controllable by IP, and link-error and egress-discard counters do not increase. Which correction addresses the demonstrated failure?
Correct answer: D - Restore a functioning IGMP querier on the media VLAN.
A newly terminated copper channel passes a simple pin-to-pin continuity check but fails near-end crosstalk testing. Inspection shows that pins 3 and 6 use conductors from different twisted pairs at both ends; each conductor still reaches the same numbered pin at the far end. How should this termination fault be classified?
Correct answer: A - A split pair.
Before an AV rack is energized, a qualified electrical inspection reports an open protective-earth connection on the rack's mains feed. The supply voltage is correct, and the rack includes a UPS that does not provide electrical isolation. No authorized electrical repairer is currently on site. The commissioning team should:
Correct answer: C - Keep the rack de-energized and arrange qualified repair before commissioning it.
The signed latency criterion for a video distribution system is a 95th-percentile end-to-end delay of no more than 40 ms at the specified peak workload. It sets no separate maximum for an individual observation. A valid test using the agreed percentile method reports 33 ms at the 95th percentile and a maximum of 61 ms. How should this latency criterion be recorded?
Correct answer: D - Pass the criterion and retain the maximum observation in the report.
An AV handover includes encrypted switch backups, hardware inventories, and current firmware records. Only the installer holds the backup decryption secret. The client's support team is required to recover a failed switch without depending on that installer. What would establish that the recovery handover is complete?
Correct answer: A - Securely transfer the recovery secret and have client support restore a compatible spare.
