Free HPE Networking Central (HPE6-A90) Practice Questions

Answer : B

Technical explanation

During a live upgrade, devices download the firmware before carefully sequenced reboot groups reduce the simultaneous coverage loss. Conduct a compatibility and dependency assessment, including whether a BIOS upgrade forces a standard interruption-based procedure. Business-hours execution can be suitable only when coverage, client mobility and supported software conditions are verified; 'live' does not guarantee zero interruption for every station or application. Track roaming, VoIP performance and reconnect attempts during the rollout, not just firmware compliance at completion.

Manual serial work is unrealistic for hundreds of APs. Scheduling an ordinary concurrent upgrade during business hours does not make the upgrade low-impact. Live Upgrade is the relevant mechanism; even then, an engineer should verify density and roaming behavior.

Answer : D

Technical explanation

AOS-10 APs send operating state, radio channel and transmit-power parameters, RF noise/retry indicators, client counts and related performance telemetry to Central. Analytics services aggregate these measurements for RF optimization, health scoring, anomaly detection and troubleshooting. Authentication secrets are not normal monitoring telemetry, and AP reporting is not a replacement for extracting arbitrary upstream router tables. When connectivity to Central is disrupted, APs can continue their currently applied forwarding and RF plans, although cloud-dependent optimizations may be delayed. A useful operational validation is to compare AP-reported RF counters and connectivity status before and after a known interference or availability event. The resulting time-series permits trend diagnosis without copying authentication credentials into the management platform.

DHCP lease information and learned routes can exist elsewhere in the topology but are not the defining AOS-10 AP telemetry category. Secret authentication material is not a routine performance-telemetry feed. Radios report operational metrics used in health and RF decisions.

Answer : A

Technical explanation

An EAP timeout indicates that an expected authentication message or reply did not arrive within its timer; it is not equivalent to an explicit credential rejection. Verify that the gateway or appropriate AP can reach the configured RADIUS server over the correct network, that shared credentials are valid and that UDP 1812 or configured RadSec connectivity functions. Inspect server logs for received requests and response latency. Only after establishing transport health should you inspect user accounts, certificates or EAP-method mismatches.

An ''EAP timeout'' is a lack of a timely authentication response, not inherently a bad password; credential failures usually create a rejection. Replacing certificates without checking network reachability can destroy useful evidence and does not restore an unreachable server. If RADIUS requests leave the gateway but responses are absent, check firewall rules, shared-secret configuration and server processing. If a timely Access-Reject returns instead, move the investigation to credentials or authorization.

Answer : A

Technical explanation

The licensing distinction must be read against the actual entitlement matrix, not assumed from feature names. HPE lists base AI Insights under Foundation, while its official Classic Central AP license table lists Unified Communications and Collaboration (UCC) and Live Upgrades under Advanced. UCC visibility concerns voice/video collaboration experience; Live Upgrade is a firmware-maintenance orchestration capability. The test's answer key singles out UCC, but the wording admits another Advanced-only selection in that documented matrix.

The Foundation license includes AI Insights, making C ineligible as an Advanced-only distinction. However, HPE's official Classic Central license table places both UCC and Live Upgrades in the Advanced column. Accordingly, A is the supplied key but B also satisfies the literal wording; the question is not unambiguous as a single-choice item.

Source-specific qualification: HPE's AP Foundation and Advanced License table places both UCC and Live Upgrades under Advanced. A single-answer interpretation of this question therefore requires the intended curriculum/release context.

Answer : B

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.
