質問 # 26
What information can be viewed from the Client Details page?
- A. Client connection history and performance metrics
- B. Device serial number only
- C. Switch port configuration templates only
正解：A
解説：
The Client Details page provides comprehensive information about connected clients, including connection duration, authentication status, roaming history, and performance statistics.
質問 # 27
Several users report failed authentication. Which HPE Aruba Networking Central tool gives the most direct insight?
- A. Client dashboard
- B. Client Event Log
- C. Site Inventory
正解：B
解説：
The Client Event Log provides detailed authentication event records, including failure reasons, timestamps, and retry attempts. This makes it the most direct and reliable tool for diagnosing and verifying authentication issues affecting multiple users.
質問 # 28
You want to prevent edge ports from creating loops if patched together. Which protection should you enable?
- A. Configure BPDU-filter on all ports.
- B. Configure Root Guard on all ports.
- C. Enable BPDU Guard on all edge ports.
正解：C
解説：
BPDU Guard is used on edge (access) ports to immediately disable a port if a BPDU is received, which indicates an unintended switch connection. This prevents accidental loops caused by users patching switch-capable devices into edge ports.
質問 # 29
A retail stack must survive a member failure with minimal disruption. Which configuration in HPE Aruba Networking Central addresses this goal?
- A. VSF with proper member roles and link design
- B. A VSX stack with two or more members and MC-LAG
- C. Create a VRF per switch for redundancy
正解：B
解説：
A VSX-based design with multiple members and MC-LAG provides high availability by maintaining independent control planes while ensuring active-active forwarding. This allows traffic to continue flowing with minimal disruption if one stack member fails, making it suitable for retail environments requiring resilient redundancy.
質問 # 30
You need to interact with a remote device through a command-line interface. Which HPE Aruba Networking Central feature allows that?
- A. Template groups with multi-edit
- B. Remote Console service from the Troubleshoot page
- C. OOBM connection from the Troubleshoot page
正解：B
解説：
The Remote Console service in the Troubleshoot page provides direct CLI access to managed devices, allowing administrators to execute commands and perform real-time diagnostics from HPE Aruba Networking Central.
質問 # 31
AOS10 shows "Auth Timeout" for several clients. What should you check first?
- A. VLAN assignment.
- B. DNS records.
- C. RADIUS server reachability and response time.
正解：C
解説：
"Auth Timeout" in AOS-10 indicates that authentication requests are not receiving timely responses from the authentication infrastructure. The first step is to verify RADIUS server reachability and response time to confirm whether delays or connectivity issues are causing authentication timeouts.
質問 # 32
During testing of a new WPA3-Enterprise SSID, clients are failing to connect. Which should you verify first?
- A. Captive portal configuration
- B. Pre-shared key configuration
- C. EAP-TLS certificate configuration
正解：C
解説：
WPA3-Enterprise relies on 802.1X authentication using EAP methods, and in many deployments EAP-TLS is used, which requires valid and trusted certificates on both client and authentication server side. If certificates are missing, invalid, or not trusted, clients will fail to authenticate and connect.
質問 # 33
Which type of device can be managed directly by Aruba Central?
- A. Access Points only
- B. Access Points, Switches, and Gateways
- C. Switches only
正解：B
解説：
Aruba Central provides unified management for wireless access points, switches, and gateways from a single cloud-based platform.
質問 # 34
HPE Aruba Networking Central shows recurring AP reboots in one site. Which AI feature helps identify the cause?
- A. RF Health report.
- B. Stability Insight dashboard.
- C. Topology viewer.
正解：B
解説：
The Stability Insight dashboard is specifically designed to track and analyze patterns of device instability, such as recurring reboots or crashes. It aggregates telemetry data to pinpoint the underlying cause-whether it stems from power issues (PoE), software exceptions, or hardware failures. By correlating these events, it provides administrators with a clear view of systemic issues affecting site-wide uptime rather than just showing isolated hardware alerts.
質問 # 35
Which is mandatory when provisioning devices in HPE Aruba Networking Central?
- A. Create a management VRF profile
- B. Assigning devices to a site and a group
- C. Create an SMPV3 profile
正解：B
解説：
Device provisioning in HPE Aruba Networking Central requires assigning devices to a group and a site so that configuration inheritance, policies, and management scope are properly applied.
This ensures the device receives the correct contextual configuration from the hierarchy.
質問 # 36
You must provision 30 access switches on different sites at once with identical VLAN and syslog settings. Which feature allows this at scale?
- A. Assign new switches to their respective sites and apply VLAN and Syslog server profiles to the global level.
- B. Assign new switches to a new temporary site and apply VLAN and Syslog server profiles to that site.
- C. Assign new switches to a device group and apply VLAN and Syslog server profiles to the Device group.
正解：C
解説：
HPE Aruba Networking Central uses a group-based management architecture to push configurations to multiple devices simultaneously. By placing all 30 switches into a single device group, a common configuration profile for VLANs and syslog can be defined at the group level.
This ensures that any device added to that specific group automatically inherits the defined settings, providing a consistent and scalable deployment across multiple physical locations.
質問 # 37
Which HPE Aruba Networking Central card shows a breakdown of device count and health by site?
- A. AI Insights
- B. Device inventory
- C. Device Health
正解：C
解説：
The Device Health card is specifically designed to provide a high-level overview of the network's operational status. It organizes data by site, allowing administrators to see a numerical breakdown of how many devices (APs, switches, and gateways) are online and healthy versus those experiencing issues. This card acts as a starting point for identifying specific locations that may require attention due to hardware failures or performance degradation.
質問 # 38
Which AI-powered feature helps identify the root cause of network issues?
- A. Faceplate View
- B. AIOps Insights
- C. Device Inventory
正解：B
解説：
AIOps Insights uses artificial intelligence and machine learning to analyze network telemetry, identify anomalies, and provide root-cause analysis recommendations.
質問 # 39
Which tool in HPE Aruba Networking Central lets you analyze traffic classification by application and policy?
- A. Application Visibility dashboard.
- B. Device inventory.
- C. Topology view.
正解：A
解説：
The Application Visibility dashboard provides deep packet inspection (DPI) data, allowing administrators to monitor and analyze the specific types of traffic traversing the network. It classifies data into distinct application categories and individual web applications, showing exactly how much bandwidth each consumes. This tool is essential for verifying that traffic is being correctly identified and handled according to the defined Quality of Service (QoS) and security policies.
質問 # 40
AI Insights suggests overlapping channels on multiple APs. What is the most efficient corrective action?
- A. Review and apply the AI recommendation.
- B. Disable Airmatch temporarily.
- C. Manually reconfigure all APs.
正解：A
解説：
HPE Aruba Networking Central utilizes AI Insights to continuously monitor the network and identify performance bottlenecks like co-channel interference. When overlapping channels are detected, the system generates specific, validated recommendations to optimize the RF environment. Applying these AI-driven recommendations is the most efficient approach because it leverages automated analysis to resolve the conflict across multiple access points simultaneously, eliminating the need for time-consuming manual channel planning or individual device reconfiguration.
