質問 # 52
Operations want a visual of active wired ports and link speed. Which HPE Aruba Networking Central view provides this at a glance?
正解：C
解説：
Technical explanation
The switch faceplate condenses a large port table into physical positions that resemble the chassis. Link coloring distinguishes connected, down, and disabled interfaces; selecting a port exposes negotiated speed
/duplex, neighboring devices and other relevant interface diagnostics. If a port unexpectedly negotiates at a lower speed, check transceiver type, auto-negotiation, cabling and peer settings. Hardware health reports CPU, fans, temperature and power supplies, which are important but do not substitute for per-interface link visibility.
The Hardware card addresses chassis components, and Device Health summarizes operational condition.
Neither presents the port-by-port speed/status layout needed by operations. On AOS-CX the card also separates RJ45 and QSFP port groups. In Central, open the managed switch's Network dashboard and expand Wired Interfaces; the faceplate hover fields include speed/duplex and PoE status.

質問 # 53
Where can you find a timeline of connection events for a specific wireless client in HPE Aruba Networking Central?
正解：C
解説：
Technical explanation
The client's Events card builds a chronology of connection transitions, enabling operators to correlate disassociation, failed authentication, roaming and IP address assignment. Preserve the client's MAC address and the interval under review because randomized MAC behavior can make a user appear as multiple identities. A device configuration page shows intended WLAN settings, and the RF dashboard captures environmental data, but neither provides the direct per-client event sequence. Use the timeline to identify the first failing stage before investigating downstream services.
RF Health aggregates environmental conditions; AP Configuration describes intended parameters. The client Events card is concerned with time-stamped association, authentication and disconnection activity, the sequence needed to diagnose one station.

質問 # 54
You need to define DHCP relay settings for multiple VLANs across all access switches. Which configuration method is the most efficient?
正解：C
解説：
Technical explanation
A VLAN profile allows DHCP helper-address configuration to follow the VLAN's Layer 3 interface requirements rather than attaching IP relay settings to an unrelated physical access port. Ensure that an SVI exists and has Layer 3 reachability to the DHCP server; DHCP relay is meaningful on the routing device that receives the broadcast. Scope the VLAN profile to the intended site and device functions and check whether any switch needs a unique local SVI address. Validate that both request and reply traffic can traverse the VRF and ACL policies. The VLAN profile workflow starts at Configuration > VLANs & Networks > VLAN > Create Profile, with the desired scope and switch function selected.
A port profile describes physical or logical interface attributes, not VLAN-specific relay across all switches.
A generic System profile does not replace the VLAN/SVI-facing helper relationship; tie the helper to the routed VLAN at the intended scope. Be precise about the Layer 3 termination: DHCP relay runs where the client VLAN broadcast reaches a routed VLAN interface. Defining a helper on a switch that only transports the VLAN at Layer 2 will not relay those broadcasts.

質問 # 55
HPE Aruba Networking Central shows frequent disconnections on a specific SSID. Where can you visualize this over time?
正解：A
解説：
Technical explanation
The client summary provides a population-level view of association and connectivity patterns within the selected time window. Narrow the view by SSID, site, AP or client identity to distinguish widespread service instability from a handful of devices. Inspect detailed client events to identify whether drops are tied to reassociation, authentication failures, DHCP renewals or AP connectivity loss. A topology map is useful for path context but not as a primary history plot; RF optimization focuses on the physical radio environment instead of user sessions.
A topology map reveals AP connectivity but does not itself chart a client's connection history. RF Optimization diagnoses radio conditions; it cannot substitute for a time-ordered list of session drops for the specific SSID and clients.

質問 # 56
Which tool in HPE Aruba Networking Central lets you analyze traffic classification by application and policy?
正解：C
解説：
Technical explanation
Application Visibility uses traffic classification, including DPI where supported, to show application families, usage and performance context rather than merely physical neighbors. Filter by site, wired/wireless client, time window and application category to identify misuse or policy-impacting traffic. Compare classified flows with user-role rules, access controls and QoS treatment. Encryption limits the visibility of payload contents, so classification often relies on signatures, protocol characteristics and metadata; it should not be confused with unrestricted decryption of every application session.
A topology diagram does not categorize application flows, and inventory only identifies assets. Application Visibility supplies classified usage information that can be compared with QoS and role-based policies, subject to the available telemetry and DPI capabilities.
