HPE2-W12

Explanation:
The correct answer is B because as remote workforces expand, traditional VPN solutions have become a major challenge for IT teams. VPNs are complex to scale, create management overhead, and introduce performance bottlenecks. HPE Aruba Networking highlights that organizations increasingly need to move from VPN-based access to Zero Trust Network Access (ZTNA)and SASEmodels to simplify operations and improve security.
Relevant extracts from official HPE Aruba Networking documentation:
“Traditional VPNs are complex, hard to scale, and increase operational burden for IT teams supporting large remote workforces.”
“Remote workforce expansion has exposed the limitations of VPN architectures, including poor user experience, difficulty scaling, and excessive troubleshooting requirements.”
“ZTNA provides a simplified alternative to VPN by offering application-specific access with least privilege, reducing complexity and support requirements.”
“With Aruba’s SSE and ZTNA solutions, organizations can eliminate VPN sprawl while improving both security and user experience.”
Why the other options are incorrect:
A. While external traffic does increase, modern data centers are designed to handle distributed traffic patterns―this is not the primary challenge.
C. Lack of Wi-Fi 6 support at home is a limitation but not a core IT admin challenge.
D. Traffic shift away from campus is true, but the bigger issue is the complexity of managing VPN solutions for remote users.

Explanation:
The correct answer is A because Aruba Central with Device Insightprovidesreal-time discovery, classification, and monitoring of all connected devices―including IoT, BYOD, and corporate endpoints. This visibility is essential for identifying unmanaged or rogue devices, applying role-based access, and minimizing risks that come from a rapidly expanding device landscape.
Relevant extracts from official HPE Aruba Networking documentation:
“Device Insight in Aruba Central uses AI/ML to automatically discover and profile all devices, including IoT and personal endpoints, with high confidence.”
“By providing continuous visibility and monitoring, Device Insight enables IT to detect rogue or misbehaving devices before they become a threat.”
“Central integrates with ClearPass to enforce least-privilege access policies based on device type and context.”
“This capability helps security admins close blind spots and manage risks associated with the proliferation of IoT and unmanaged devices.”
Why the other options are incorrect:
B. GreenLake for Networking is a consumption and service model, not a feature directly tied to IoT and personal device risk management.
C. Unified Infrastructure simplifies multi-domain management but does not directly address device-level visibility and risk.
D. SD-WAN does not solve the IoT/personal device visibility challenge; it is focused on WAN optimization and security.

Explanation:
The correct answer is C because Aruba Central leverages AI-powered insights and automation to recommend security and access policies that administrators can preview and apply directly. This helps simplify policy management and ensures consistent enforcement without requiring manual configuration for every change.
Relevant extracts from official HPE Aruba Networking documentation:
“Aruba Central provides AI-powered policy recommendations that reduce configuration complexity and allow IT administrators to preview and apply them quickly.”
“With automated policy enforcement across wired, wireless, and WAN, Aruba Central simplifies protecting the network by ensuring consistent access control for users and devices.”
“Central’s role-based policy recommendations align with Aruba’s Zero Trust security framework, minimizing risk while reducing administrative overhead.”
“By integrating AI/ML insights, Aruba Central helps IT move from reactive troubleshooting to proactive security policy enforcement.”
Why the other options are incorrect:
A. While Aruba does integrate with private 5G, this is not the primary way Aruba Central simplifies security.
B. A sandbox environment for malware inspection is not a feature of Aruba Central; this is typically delivered by third-party security integrations.
D. Aruba Central provides policy recommendations, but it does not automatically create and add rules without admin oversight. Admin approval is required for changes, maintaining operational control.

Explanation:
The correct answer is B because Aruba Central addresses the need for continuous optimization and operational efficiency by providing AI-driven recommendations, anomaly detection, and performance insights. These capabilities help network admins proactively manage performance, improve user experience, and reduce troubleshooting overhead.
Relevant extracts from official HPE Aruba Networking documentation:
“Aruba Central leverages AI/ML to provide actionable insights and recommendations to optimize network performance.”
“By continuously monitoring the health of the network and user experience, Aruba Central ensures IT can proactively identify and resolve issues.”
“AI recommendations empower IT staff to focus on strategic initiatives rather than reactive troubleshooting, enhancing operational efficiency.”
“Aruba Central transforms operations by consolidating management across LAN, WLAN, and WAN, while improving performance with automated optimization.”
Why the other options are incorrect:
A is incorrect: Aruba Central emphasizes ongoing monitoring, management, and optimization; it is not a “set and forget” solution.
C is incorrect: Aruba Central does not eliminate the need for network admins―it enhances their efficiency, not replaces them.
D is incorrect: Aruba Central’s strength is breaking down silos by unifying management across wired, wireless, and WAN, not managing them separately.

Explanation:
The correct answer is A because Aruba Network Insights, a feature of Aruba Central’s AI-powered operations (AIOps), focuses on identifying performance issues and providing actionable, prescriptive recommendations to resolve them. This enables IT teams to proactively address network issues before they impact end users, improving operational efficiency and minimizing downtime.
Relevant extracts from official HPE Aruba Networking documentation:
“Aruba Central AIOps with Network Insights provides actionable recommendations to resolve network performance issues.”
“AI/ML-based analytics continuously monitor network health, identifying anomalies and performance degradations.”
“By offering prescriptive guidance, Central reduces mean time to resolution (MTTR) and empowers IT teams to optimize the network.”
“Network Insights transforms reactive troubleshooting into proactive operations by identifying issues early and suggesting corrective actions.”
Why the other options are incorrect:
B. Blocking suspicious clients is part ofClearPass Policy Manager and Zero Trust enforcement, not Network Insights.
C. Searching for users and endpoints with automated resolution aligns more with ClearPass and Client Insights, not Network Insights.
D. IoT profiling is handled by Device Insight, not Network Insights.
