HPE Networking Central Exam HPE6-A90 Prüfungsfragen mit Lösungen (Q19-Q24):

19. Frage
You are planning to isolate guest and IoT networks on campus. How can you configure separate routing tables and policies per tenant using HPE Aruba Networking Central?

Antwort: B

Begründung:
Virtual Routing and Forwarding (VRF) allows a single physical switch or router to host multiple independent routing table instances simultaneously. By configuring separate VRF profiles for Guest and IoT traffic, you ensure complete control-plane and data-plane isolation; traffic in one VRF is invisible to another, allowing for overlapping IP addresses if necessary and the application of unique routing policies per tenant or network segment.


20. Frage
A guest SSID requires captive portal access. Which setting enables this in HPE Aruba Networking Central?

Antwort: B

Begründung:
Technical explanation
The WLAN security and access configuration defines how unauthenticated clients reach the portal, what redirect URL or hosted portal is used, and how successful authentication changes the user's role. Configure the pre-authentication role so clients can resolve DNS and reach the portal while remaining blocked from protected services. The precise wizard tab differs across Central interface versions, but the captive-portal behavior belongs to the SSID's access/authentication workflow, not merely to a VLAN definition. Validate the redirect on multiple operating systems.
ClearPass may supply identity or guest services, but merely naming its Guest role does not configure HTTP redirection. The Guest security level alone does not replace a captive-portal profile, its pre-authentication rules, or the portal URL.

21. Frage
What must an organization do before managing devices in HPE Aruba Networking Central through HPE GreenLake?

Antwort: A

Begründung:
Technical explanation
A GreenLake workspace defines the organizational boundary containing services, users, resource associations and access controls. Establish the workspace, grant appropriate administrator rights and then onboard or assign devices and subscriptions to the Central application. Subscription tier selection remains an important later step but is not the organizational prerequisite asked here. Ensure that invited users and devices are associated with the correct workspace to avoid accidental cross-tenant visibility or assigning entitlements to an unintended environment.
Assigning subscriptions and enabling auto-assignment follow the existence of an organizational workspace.
Compliance data upload is not the prerequisite to creating a Central service. Workspace and roles establish the management boundary first.

22. Frage
Which design ensures continuous WLAN coverage if an AP fails?

Antwort: A

Begründung:
Technical explanation
Design overlapping coverage cells such that a client can detect and associate to an alternative AP if a neighbor fails. Validate the secondary AP's signal strength, channel availability and capacity under a failure scenario rather than relying on a fixed overlap percentage. Survey from client height and account for wall attenuation, antenna patterns and voice-roaming requirements. Setting maximum EIRP everywhere tends to enlarge contention domains, while forcing all radios onto one channel undermines spatial reuse and reliable failover.
A single shared channel causes more co-channel contention, not resilient coverage. Maximum transmit power may make APs visible from farther away while clients still lack a viable return link. Redundancy requires usable neighboring coverage with capacity to absorb failures.

23. Frage
AI Insights suggests overlapping channels on multiple APs. What is the most efficient corrective action?

Antwort: B

Begründung:
Technical explanation
AI-derived RF recommendations should be assessed against channel quality, neighboring AP assignments, regulatory limits and the operational change window. AirMatch computes channel, bandwidth and power plans from aggregated AP telemetry, rather than assuming every AP requires a manual static channel.
Confirm the recommendation fits the affected site's survey and any reserved channels before permitting changes. Disabling AirMatch eliminates the automation that normally manages RF resource reuse and is not a logical response to detected overlap.
Manually rebuilding every AP channel plan discards the fleet-wide context of AirMatch. Disabling AirMatch removes the optimization mechanism that can correct overlap. Check the recommendation's assumptions and scope before applying it.
