ACP Assessment & Evaluation Techniques 3 — Questions and Answers
Question 1: When evaluating Aruba network security posture, which ClearPass report identifies devices that failed posture assessment and were quarantined?
- Endpoint Activity Report
- OnGuard Compliance Report (Correct answer)
- Guest Access Report
- RADIUS Authentication Report
Correct answer: OnGuard Compliance Report
The OnGuard Compliance Report in ClearPass specifically tracks devices that failed health checks and the enforcement actions taken.
Question 2: During a network assessment, an Aruba engineer finds that a specific SSID shows poor association success rates. Which Aruba tool provides per-SSID association statistics in real time?
- Aruba Central AI Insights (Correct answer)
- Aruba IMC
- Aruba AirWave RF Dashboard
- Aruba Activate
Correct answer: Aruba Central AI Insights
Aruba Central AI Insights uses AIOps to surface per-SSID association success rates and anomaly detection in real time.
Question 3: Which key performance indicator (KPI) is MOST relevant when evaluating VoIP quality on an Aruba wireless network?
- Aggregate throughput
- Mean Opinion Score (MOS) (Correct answer)
- Number of associated clients
- AP uptime percentage
Correct answer: Mean Opinion Score (MOS)
MOS (Mean Opinion Score) directly quantifies voice call quality perceived by users, making it the primary KPI for VoIP assessment.
Question 4: An Aruba administrator uses the 'show ap debug radio-stats' CLI command. What is the primary purpose of this command during a performance evaluation?
- Display AP license status
- Show real-time radio counters including retry and error rates (Correct answer)
- List all associated clients and their IP addresses
- Show the current ARM power and channel assignment
Correct answer: Show real-time radio counters including retry and error rates
The 'show ap debug radio-stats' command provides real-time per-radio statistics including retries, errors, and frame counts critical for performance troubleshooting.
Question 5: When assessing Aruba SD-WAN path quality, which metric measures the variation in packet arrival times that most affects real-time applications?
- Throughput
- Packet Loss
- Jitter (Correct answer)
- MTU size
Correct answer: Jitter
Jitter (variation in packet inter-arrival time) is the critical SD-WAN metric for real-time applications like voice and video.
Question 6: In Aruba Central, which feature allows administrators to set thresholds and receive automated alerts when network KPIs degrade?
- Webhooks
- Alert Profiles (Correct answer)
- AIOps Baselines
- Site Health Score
Correct answer: Alert Profiles
Alert Profiles in Aruba Central let administrators configure custom thresholds on KPIs and trigger notifications when those thresholds are exceeded.
Question 7: During a security assessment, an Aruba engineer discovers rogue APs using the same SSID as the corporate network. Which Aruba feature classifies and contains such devices?
- Adaptive Radio Management (ARM)
- Wireless Intrusion Detection/Prevention System (WIDS/WIPS) (Correct answer)
- Client Match
- AirGroup
Correct answer: Wireless Intrusion Detection/Prevention System (WIDS/WIPS)
Aruba WIDS/WIPS continuously monitors the RF environment, classifies rogue APs, and can automatically contain them to protect the network.
