1. Which of the following scenarios most clearly represents a conflict of interest for an ACP-certified consultant advising on wireless infrastructure procurement? → Recommending a vendor whose products the consultant personally holds undisclosed equity in
2. What is the purpose of Aruba AI Insights in Aruba Central? → To provide AI-driven anomaly detection and troubleshooting recommendations
3. Which Aruba product line is designed for small businesses with simplified cloud management? → Aruba Instant On
4. Which Aruba best practice reduces the risk of rogue APs going undetected in a campus environment? → Enable Aruba WIDS/WIPS with rogue AP detection and containment in the wireless policy
5. What is the purpose of Spanning Tree Protocol (STP) in switched networks? → To prevent Layer 2 loops by blocking redundant paths in a switched network
6. What is the significance of professional networking in the Aruba Certified Professional field? → It facilitates knowledge exchange, referrals, and collaborative problem-solving
7. Which Aruba Central feature sends automated alerts when client experience scores drop below a defined threshold? → AI Insights Alert Rules / Notifications
8. An Aruba network engineer performs a penetration test against the wireless infrastructure. How does this activity relate to risk management? → It identifies vulnerabilities that can then be prioritized and mitigated
9. What is the consequence of practicing outside the defined scope of practice? → Potential license revocation, legal liability, and risk to public safety
10. In ClearPass Policy Manager, what is a 'Posture Policy' used for? → Assessing endpoint health (antivirus, patch level, OS) and returning a posture token
11. What does 802.11r (Fast BSS Transition) improve in a wireless environment? → Roaming speed between APs by pre-authenticating before disassociation
12. When assessing Aruba switch stack performance, which metric indicates that the stacking interconnect is a bottleneck? → Elevated stack port error rates and drops
13. In a full-duplex Ethernet connection, what is eliminated compared to half-duplex? → CSMA/CD collisions
14. Which ArubaOS tunnel mode encapsulates all wireless client traffic in GRE and forwards it to the mobility controller? → Tunnel Mode
15. A technician uses 'show ap debug counters' on an Aruba controller and sees high 'tx-drop' values on an AP. What does this most likely indicate? → The AP's transmit buffer is overflowing due to RF congestion or a rate mismatch
16. How should strategic objectives be defined? → Using SMART criteria: Specific, Measurable, Achievable, Relevant, Time-bound
17. Which Aruba Instant feature provides a built-in RADIUS server to authenticate clients when no external RADIUS is available? → Internal RADIUS Server (internal server authentication)
18. What is the maximum transmission unit (MTU) for standard Ethernet frames? → 1500 bytes
19. Which document type is MOST appropriate for capturing the step-by-step process to recover an Aruba controller after a firmware failure? → Runbook
20. What is the function of Target Wake Time (TWT) in 802.11ax (Wi-Fi 6)? → Schedule specific times for clients to wake and communicate, reducing power consumption
21. An AP configured in Spectrum Monitor mode primarily performs which function? → Scan the RF spectrum to detect non-802.11 interference sources
22. In ClearPass Policy Manager, what is the purpose of a Role Mapping Policy? → To map user or device attributes to defined roles used in authorization decisions
23. Which communication practice BEST ensures that field technicians performing Aruba AP installations acknowledge they have read the site survey documentation? → Requiring a digital signature on the document
24. When configuring a network interface in Aruba AOS-S, what is the effect of placing a port in 'access' mode with VLAN 20? → The port carries only untagged VLAN 20 traffic
25. When evaluating Aruba network readiness for IoT deployments, which segmentation technique is recommended to isolate IoT devices from corporate assets? → Dynamic Segmentation with Aruba Policy Enforcement Firewall (PEF)
26. When troubleshooting an Aruba SD-WAN deployment, which command verifies the health and uptime of overlay tunnels between branch and hub? → show datapath tunnel
27. A network leader must communicate a major architecture change to non-technical executives. What communication strategy is most effective? → Use a one-page business impact summary with a risk and benefit table
28. When documenting an Aruba network change, which field in a change request is MOST critical for communicating impact to stakeholders? → Risk and rollback plan
29. What is WPA3-SAE (Simultaneous Authentication of Equals) designed to protect against compared to WPA2-PSK? → Offline dictionary attacks against captured 4-way handshakes
30. A network leader is tasked with developing a zero-trust security strategy. Which stakeholder group should be engaged first in the planning process? → Business unit leaders to understand critical data flows and risk tolerance
