Read the first 7 Quality Control & Process Improvement flashcards as text

  1. Which 802.11 standard feature, when misconfigured, most commonly degrades overall WLAN performance in high-density environments?

    Answer: Legacy data rate support (1 and 2 Mbps)

    Enabling legacy low data rates causes slower clients to occupy airtime longer, degrading throughput for all users in the cell.

  2. What is the purpose of a pre-deployment checklist in a wireless installation project?

    Answer: To ensure all materials, configurations, and site conditions are ready before installation begins

    A pre-deployment checklist reduces on-site errors by confirming readiness of equipment, site access, and configuration templates before work begins.

  3. During a WLAN QC audit, you discover that several APs are operating on the same channel within range of each other. This condition is called:

    Answer: Co-channel interference (CCI)

    Co-channel interference occurs when multiple APs share the same channel and their coverage cells overlap, causing contention.

  4. A root cause analysis (RCA) after a failed wireless deployment should focus on:

    Answer: Identifying systemic process failures to prevent recurrence

    Effective RCA targets process breakdowns and systemic issues rather than individuals to drive lasting improvement.

  5. Which KPI best reflects the effectiveness of a wireless network's QoS configuration for voice traffic?

    Answer: Mean Opinion Score (MOS) or jitter levels

    MOS and jitter are the most direct indicators of voice call quality over a wireless network.

  6. When updating firmware on deployed access points as part of a quality improvement initiative, best practice dictates:

    Answer: Staging the update on a test AP first and rolling out during a maintenance window

    Staging firmware on a test unit and deploying during off-peak maintenance windows minimizes production risk.

  7. In wireless project management, a 'lessons learned' session is BEST conducted:

    Answer: At project closeout, after deliverables are accepted

    Lessons learned sessions at closeout capture institutional knowledge while the project is fresh and feed future process improvements.
