NEW QUESTION # 13
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
Answer: C
Explanation:
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.
NEW QUESTION # 14
Which Aruba Central capability assists with troubleshooting wireless roaming issues?
- A. Client Timeline
- B. Group Configuration
- C. Device Inventory
Answer: A
Explanation:
The Client Timeline provides a chronological record of client activities, including association, authentication, roaming events, and disconnects.
NEW QUESTION # 15
A customer needs consistent port configuration (Speed, Duplex, PoE, STP) on all access switches. Which configuration approach uses HPE Aruba Networking Central's intent-based model?
- A. Create a Port Profile and assign it to applicable interfaces
- B. Apply a Global alias only without profile linkage
- C. Configure interfaces for every switch individually
Answer: A
Explanation:
Port Profiles in HPE Aruba Networking Central implement an intent-based configuration model that allows standardized settings (such as speed, duplex, PoE, and STP behavior) to be defined once and consistently applied across multiple access switch interfaces. This ensures uniform configuration while reducing manual per-device effort and configuration drift.
NEW QUESTION # 16
What is the primary purpose of role-based access control (RBAC) in Aruba Central?
- A. Increase wireless coverage
- B. Configure switch interfaces automatically
- C. Restrict user permissions based on assigned roles
Answer: C
Explanation:
RBAC enhances security and operational control by assigning permissions according to user responsibilities, ensuring users access only authorized functions.
NEW QUESTION # 17
A campus has loops after adding a new distribution switch. Which HPE Aruba Networking Central feature should you configure to maintain a loop-free topology?
- A. BPDU guard configured on all switch ports
- B. Spanning Tree with appropriate port roles
- C. MAC Authentication for switch uplinks
Answer: B
Explanation:
Spanning Tree Protocol (STP) is the fundamental layer 2 mechanism used to prevent broadcast storms and network loops in a redundant topology. By assigning appropriate port roles-such as Root, Designated, and Blocked-STP ensures that there is only one active logical path between any two nodes on the network. When a new distribution switch is added, correctly configuring STP priorities and roles ensures that redundant physical links are intelligently managed, automatically disabling potential loop paths while maintaining network availability.
NEW QUESTION # 18
Which is mandatory when provisioning devices in HPE Aruba Networking Central?
- A. Create an SMPV3 profile
- B. Assigning devices to a site and a group
- C. Create a management VRF profile
Answer: B
Explanation:
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.
NEW QUESTION # 19
One AP shows low throughput for a subset of clients. Where should you start your investigation?
- A. Event log for WLAN changes.
- B. AP dashboard -> connectivity card.
- C. AI Insights for firmware drift.
Answer: B
Explanation:
The AP dashboard Connectivity card provides real-time and historical performance metrics for the access point, including client throughput, RF conditions, and link quality. This is the most effective starting point to identify why only a subset of clients is experiencing reduced throughput on that AP.
NEW QUESTION # 20
HPE Aruba Networking Central displays an alert for "Coverage Hole Detected." What is the recommended action?
- A. Review AP placement and RF coverage maps.
- B. Increase the minimum data rate.
- C. Increase transmit power on all APs.
Answer: A
Explanation:
A "Coverage Hole Detected" alert indicates areas where client signal strength is insufficient for reliable connectivity. The appropriate first step is to review AP placement and RF coverage maps to identify physical gaps in coverage and determine whether additional APs or repositioning is required.
NEW QUESTION # 21
What is required before adding a device to Aruba Central management?
- A. Static IP address assignment
- B. VLAN configuration
- C. Device subscription license
Answer: C
NEW QUESTION # 22
Clients report brief outages overnight. Which dashboard element helps correlate events with time windows to identify root cause?
- A. Connectivity card with static neighbor count
- B. Licenses card with subscription expiration date
- C. Events card filtered by time via the timeline widget
Answer: C
Explanation:
The Events card combined with the timeline filter enables correlation of network events against specific time windows. This helps identify patterns such as brief outages and align them with system logs or environmental changes to determine root cause.
NEW QUESTION # 23
Leadership asks how HPE Aruba Networking Central will improve operations across multiple sites. Which description applies?
- A. Cloud-native platform with AI insights, unified workflows, and APIs
- B. Using different workspaces allows multisite device management
- C. SNMPv3 allows the secure management of multiple site devices
Answer: A
Explanation:
HPE Aruba Networking Central is a cloud-native platform that centralizes multi-site network operations, using AI-driven insights, unified configuration and monitoring workflows, and extensible APIs. This combination improves operational efficiency, visibility, and automation across distributed environments.
NEW QUESTION # 24
HPE Aruba Networking Central shows frequent disconnections on a specific SSID. Where can you visualize this over time?
- A. Topology map.
- B. Client summary view.
- C. RF Optimization page.
Answer: B
Explanation:
The Client summary view provides time-based visibility of client behavior, including disconnections and session history. This allows administrators to track recurring SSID issues over time and correlate drops with client sessions for troubleshooting and trend analysis.
NEW QUESTION # 25
How does HPE Aruba Networking Central's AI contribute to predictive maintenance and performance tuning?
- A. By only generating proactive troubleshooting tickets for IT staff.
- B. By detecting anomalies, identifying root causes, and recommending proactive actions to prevent network issues.
- C. By automatically opening hardware replacement tickets without human intervention.
Answer: B
NEW QUESTION # 26
Which test verifies end-to-end connectivity between AP and gateway?
- A. Ping Test under the Troubleshoot page.
- B. Speed Test under the Device dashboard.
- C. Connectivity card under the Device dashboard.
Answer: A
Explanation:
The Ping Test located within the Troubleshoot page is the standard diagnostic tool for verifying layer 3 reachability between network nodes. By initiating a ping from an Access Point to its designated gateway, an administrator can confirm that the physical link is active and that the routing path is correctly established. This test measures the round-trip time and packet loss, providing definitive proof of whether end-to-end connectivity exists between the two specific network components.
NEW QUESTION # 27
Which tool is most useful for reviewing historical client connectivity events?
- A. Inventory Page
- B. Client Timeline
- C. Group Dashboard
Answer: B
Explanation:
Client Timeline presents a detailed historical sequence of client-related events, making it invaluable for troubleshooting intermittent connectivity issues.
