  1. What is the 802.11v standard and what feature does it add for wireless network management?

    Answer: BSS Transition Management, which allows APs to send suggestions to clients recommending they roam to a better AP

    802.11v (BSS Transition Management) enables APs to proactively suggest that clients roam to a better AP, helping the network steer clients away from congested or weak APs.

  2. Which metric best reflects the actual experience of a wireless voice or video call quality for end users?

    Answer: Mean Opinion Score (MOS) derived from latency, jitter, and packet loss measurements

    Mean Opinion Score (MOS) combines latency, jitter, and packet loss metrics into a single perceptual quality score that directly reflects user-perceived voice/video quality.

  3. What is the maximum number of spatial streams supported by 802.11ac Wave 2 (Wi-Fi 5) standard?

    Answer: 8

    802.11ac Wave 2 supports up to 8 spatial streams via MU-MIMO, enabling the AP to simultaneously transmit to multiple clients and dramatically increasing aggregate throughput.

  4. A technician notices that wireless clients in a conference room experience high latency during large meetings. Which likely cause should be investigated first?

    Answer: High client density is causing medium contention and channel saturation

    High client density causes increased 802.11 medium contention, leading to longer backoff times and elevated latency as all clients compete for airtime on the same channel.

  5. What is TSPEC (Traffic Specification) in the context of 802.11e QoS and how is it used?

    Answer: A client-initiated request that reserves bandwidth and QoS parameters with the AP for a specific traffic stream

    TSPEC is part of 802.11e admission control, allowing clients to request a specific amount of bandwidth with defined QoS parameters from the AP before initiating a real-time stream.

  6. What does the term 'client load balancing' mean in enterprise wireless deployments?

    Answer: Distributing client associations across multiple APs to prevent any single AP from becoming overloaded

    Client load balancing distributes associations across APs so that no single AP is overloaded, improving throughput and reducing latency for all clients in the area.
