HP HPE7-A01 Practice Test 5

Question 40

For an HPE Aruba Networking campus deployment, an AP uses a tagged management VLAN but the switch sends it untagged. Which action best addresses it?

Prestage device identity, inventory, group and required bootstrap network details.
Configure reachable DNS resolvers with the required records.
Check optic type, fiber polarity, speed support and receive power.
Make the AP uplink native/tagged VLAN expectation match the switch port.

Explanation

Correct Answer

AP management requires consistent tagged versus untagged treatment. The engineer should make the AP uplink native/tagged VLAN expectation match the switch port.

Incorrect Answers

Preprovisioning moves repeatable configuration into central management. It is not a direct remedy for the condition described.

Control-plane enrollment can fail when hostnames cannot resolve correctly. It is not a direct remedy for the condition described.

Physical link-up requires matching media and supported transceiver properties. It is not a direct remedy for the condition described.

Question 41

For an HPE Aruba Networking campus deployment, a long hallway AP causes clients to stay associated too far away. Which action best addresses it?

Adjust cell size, minimum basic rates and roaming policy carefully.
Use supported BSS transition management with a suitable candidate list.
Differentiate same-channel contention from adjacent-channel interference.
Consider supported higher minimum data rates after coverage verification.

Explanation

Correct Answer

Excess cell reach and very low data rates can promote sticky clients. The engineer should adjust cell size, minimum basic rates and roaming policy carefully.

Incorrect Answers

802.11v can suggest a better BSS, but the client decides whether to comply. It is not a direct remedy for the condition described.

CCI shares airtime while ACI disrupts reception through overlapping energy. It is not a direct remedy for the condition described.

Very low basic rates consume disproportionate airtime. It is not a direct remedy for the condition described.

Question 42

A downstream switch uses links to two VSX peers but sees two independent LAGs. Which change most directly meets this campus requirement?

Design a supported ring or alternate stack-link topology.
Examine VRRP priorities, preemption and advertisement reachability.
Configure the downstream bundle and upstream VSX LAG consistently.
Establish an eligible backup route and failure detection method.

Explanation

Correct Answer

Multichassis aggregation depends on coordinated LAG identity at the peer pair. The engineer should configure the downstream bundle and upstream VSX LAG consistently.

Incorrect Answers

Redundant stacking paths can preserve member connectivity after one link fails. It is not a direct remedy for the condition described.

Virtual-router election depends on priority and exchanged advertisements. It is not a direct remedy for the condition described.

Redundancy requires more than an unused physical interface. It is not a direct remedy for the condition described.

Question 43

A core switch needs a route to an offsite network not directly connected. Which change most directly meets this campus requirement?

Configure a static route with a reachable next hop in the correct VRF.
Use supported NSSA external route handling instead of ordinary stub settings.
Align interface hello/dead timers between peers.
Verify longest-prefix route selection instead of relying on next-hop metric alone.

Explanation

Correct Answer

Static forwarding requires the destination prefix and next-hop resolution. The engineer should configure a static route with a reachable next hop in the correct VRF.

Incorrect Answers

NSSA permits controlled local external redistribution in a stub-like area. It is not a direct remedy for the condition described.

Neighbor timer compatibility matters for OSPF adjacency formation. It is not a direct remedy for the condition described.

More-specific prefixes normally override less-specific matches in route lookup. It is not a direct remedy for the condition described.

Question 44

During campus implementation, an operator needs to preserve switch configuration before a risky upgrade. What should the engineer configure or correct?

Verify NAE command authorization under the intended AAA policy.
Review the configuration audit and reconcile the intended group settings.
Export a supported backup or checkpoint and record rollback steps.
Schedule a supported firmware update and compare compatibility.

Explanation

Correct Answer

Recovery requires a known-good configuration and compatible restore method. The engineer should export a supported backup or checkpoint and record rollback steps.

Incorrect Answers

NAE operations may be constrained by command authorization. It is not a direct remedy for the condition described.

Configuration intent and installed running state must be compared. It is not a direct remedy for the condition described.

Version management requires appropriate platform images and maintenance windows. It is not a direct remedy for the condition described.

Question 45

The campus team is closing a service ticket about this condition: An uplink needs to limit one large backup application's bandwidth. Which validation step is most relevant?

Compare per-class airtime occupancy and application quality.
Compare throughput and drop profiles before and after rate control.
Run multiple varied flows and inspect member counters.
Compare HE capability and airtime resource-unit statistics.

Explanation

Correct Answer

Shaping buffers over-rate traffic while policing can drop or remark it. Compare throughput and drop profiles before and after rate control directly tests the desired behavior.

Incorrect Answers

Equal byte throughput is not the same as equal shared radio airtime. That observation tests a different condition, not the required result.

LAG hashing keeps a flow on one member and does not split one flow packet by packet. That observation tests a different condition, not the required result.

OFDMA benefits depend on both AP and client support and actual traffic mix. That observation tests a different condition, not the required result.

Question 46

A network team reports the following condition: An Aruba Central user needs repeatable read-only device queries. Select the most appropriate response.

Deploy UXI sensors with appropriate internal/external tests.
Use the documented authenticated REST API and appropriate role.
Review the configuration audit and reconcile the intended group settings.
Schedule a supported firmware update and compare compatibility.

Explanation

Correct Answer

APIs allow programmatic access while permissions control scope. The engineer should use the documented authenticated REST API and appropriate role.

Incorrect Answers

Synthetic user-experience probes reveal service reachability and performance. It is not a direct remedy for the condition described.

Configuration intent and installed running state must be compared. It is not a direct remedy for the condition described.

Version management requires appropriate platform images and maintenance windows. It is not a direct remedy for the condition described.

Question 47

The campus team is closing a service ticket about this condition: A client fails EAP-TLS because its certificate lacks the right identity mapping. Which validation step is most relevant?

Trigger CoA and observe role transition and permitted applications.
Inspect certificate subject/SAN and RADIUS policy trace.
Inspect RADIUS attributes and the port's applied VLAN.
Review start, interim and stop accounting messages for a session.

Explanation

Correct Answer

Authorization must map the authenticated certificate identity to the intended user/device. Inspect certificate subject/SAN and RADIUS policy trace directly tests the desired behavior.

Incorrect Answers

Change of Authorization can update session policy without a full reboot. That observation tests a different condition, not the required result.

Authentication success and assigned authorization policy are separate decisions. That observation tests a different condition, not the required result.

Accounting records session events rather than selecting the identity. That observation tests a different condition, not the required result.

Question 48

An engineer is planning corrective work because an AP passes traffic but a connected downstream IoT device cannot. Which step should be prioritized?

Validate the AP wired-port bridge mode, allowed VLAN and required access policy.
Check device inventory, subscription assignment and outbound management reachability.
Investigate lease, gateway and address conflict information.
Negotiate or explicitly align supported speed and duplex settings.

Explanation

Correct Answer

The AP uplink does not automatically grant all attached wired port traffic. The engineer should validate the AP wired-port bridge mode, allowed VLAN and required access policy.

Incorrect Answers

Cloud onboarding requires identity, entitlement and network communication, not only an IP address. It is not a direct remedy for the condition described.

Duplicate management addresses or unstable DHCP assignments break control-plane reachability. It is not a direct remedy for the condition described.

Link establishment depends on mutually supported PHY settings. It is not a direct remedy for the condition described.

Question 49

An access interface has a compatible optic but the link remains down. Which change most directly meets this campus requirement?

Check optic type, fiber polarity, speed support and receive power.
Validate the management VRF default route and allowed outbound paths.
Align supported member images and the stack compatibility requirements.
Verify the intended gateway virtualization design and L2 loop condition.

Explanation

Correct Answer

Physical link-up requires matching media and supported transceiver properties. The engineer should check optic type, fiber polarity, speed support and receive power.

Incorrect Answers

A reachable local interface does not imply a usable route from the management VRF. It is not a direct remedy for the condition described.

Stack membership commonly requires compatible software and platform capabilities. It is not a direct remedy for the condition described.

Unplanned gateway MAC movement can reflect duplicated gateway identity or loops. It is not a direct remedy for the condition described.

Question 50

OSPF neighbors use unequal hello and dead intervals. Which change most directly meets this campus requirement?

Integrate supported BFD on the relevant routed interfaces.
Align interface hello/dead timers between peers.
Apply the intended stub-area design consistently on peers.
Tune supported interface costs consistently with the topology.

Explanation

Correct Answer

Neighbor timer compatibility matters for OSPF adjacency formation. The engineer should align interface hello/dead timers between peers.

Incorrect Answers

BFD can drive rapid protocol fault detection independent of standard hello timers. It is not a direct remedy for the condition described.

Stub-area properties constrain external route advertisement. It is not a direct remedy for the condition described.

OSPF SPF uses accumulated interface metrics for path selection. It is not a direct remedy for the condition described.
