HP HPE7-A01 Practice Test 25

Question 240

Following a campus change for this issue—a switch's default administrative password is shared among technicians—which result most directly verifies that the remedy works?

Attempt traffic from an unexpected VLAN and inspect frame classification.
Verify PMF negotiated and controlled spoofed disconnect is rejected.
Try an allowed operation and a restricted admin operation.
Simulate RADIUS outage and observe the assigned critical role.

Explanation

Correct Answer

Individual accounts enable accountability and least-privilege authorization. Try an allowed operation and a restricted admin operation directly tests the desired behavior.

Incorrect Answers

Incorrect allowed/native VLAN settings weaken L2 segmentation. That observation tests a different condition, not the required result.

Protected management frames prevent unauthenticated robust management manipulation. That observation tests a different condition, not the required result.

Authentication outages need controlled failover permissions. That observation tests a different condition, not the required result.

Question 241

A band-steering policy makes older 2.4-only scanners disappear. Which change most directly meets this campus requirement?

Use a compatible band-steering mode with necessary 2.4 GHz fallback.
Review ARM/AirMatch bounds and actual cell overlap.
Consolidate SSIDs when policy requirements permit.
Measure SNR, interference and channel busy time.

Explanation

Correct Answer

A forced 5 GHz policy can exclude clients that lack that band. The engineer should use a compatible band-steering mode with necessary 2.4 GHz fallback.

Incorrect Answers

Excess transmit power can enlarge contention cells and delay roaming. It is not a direct remedy for the condition described.

Each SSID adds beacon and management overhead to the channel. It is not a direct remedy for the condition described.

RSSI alone cannot identify noise or contention-driven retries. It is not a direct remedy for the condition described.

Question 242

For an HPE Aruba Networking campus deployment, an application is marked EF but packets remain in the best-effort queue. Which action best addresses it?

Optimize multicast delivery and eligible wireless rates.
Reduce channel width when reuse and contention require it.
Correct the DSCP-to-local-queue mapping and trust boundary.
Consider 802.11r/k/v support and authentication-path tuning.

Explanation

Correct Answer

Classification and queue scheduling both matter for end-to-end QoS. The engineer should correct the DSCP-to-local-queue mapping and trust boundary.

Incorrect Answers

Multicast transmissions can consume disproportionate shared airtime. It is not a direct remedy for the condition described.

Wide channels can reduce the number of independent neighboring cells. It is not a direct remedy for the condition described.

Roaming performance depends on scan, authentication and mobility handling. It is not a direct remedy for the condition described.

Question 243

A network team reports the following condition: A spanning-tree design converges slowly after an access link fails. Select the most appropriate response.

Use the supported RSTP/MSTP mode and verify topology roles.
Use an AP/switch design with supported wired failover and consistent VLAN policy.
Avoid a single common aggregation point in the physical topology.
Map VLANs to supported MSTP instances with appropriate roots.

Explanation

Correct Answer

Rapid spanning tree speeds appropriate topology changes compared with legacy STP. The engineer should use the supported RSTP/MSTP mode and verify topology roles.

Incorrect Answers

Failover paths must preserve required management and client VLAN reachability. It is not a direct remedy for the condition described.

Device redundancy is ineffective when both paths depend on one shared failed component. It is not a direct remedy for the condition described.

MSTP can provide separate spanning-tree topologies for groups of VLANs. It is not a direct remedy for the condition described.

Question 244

Following a campus change for this issue—a wireless AP reaches a controller but client traffic cannot reach a server—which result most directly verifies that the remedy works?

Compare authentication exchange duration during controlled roaming.
Compare spectrum occupancy with AP channel utilization.
Test representative single-band and dual-band scanners.
Trace the client role, VLAN, gateway and policy path.

Explanation

Correct Answer

Management connectivity does not automatically grant data-plane reachability. Trace the client role, VLAN, gateway and policy path directly tests the desired behavior.

Incorrect Answers

Fast transition can reduce reassociation authentication overhead. That observation tests a different condition, not the required result.

Microwave, Bluetooth and industrial emitters can raise noise without being an 802.11 AP. That observation tests a different condition, not the required result.

A forced 5 GHz policy can exclude clients that lack that band. That observation tests a different condition, not the required result.

Question 245

A port should accept only approved hardware addresses. Which change most directly meets this campus requirement?

Apply supported port-security learning and violation handling.
Enable supported dynamic ARP inspection using valid bindings.
Enable appropriate IGMP snooping and confirm listener groups.
Align link negotiation and duplex compatibility.

Explanation

Correct Answer

Port security restricts which endpoint MAC addresses can use the link. The engineer should apply supported port-security learning and violation handling.

Incorrect Answers

Dynamic ARP inspection can reject ARP packets inconsistent with trusted bindings. It is not a direct remedy for the condition described.

IGMP snooping limits eligible multicast delivery to interested ports. It is not a direct remedy for the condition described.

Duplex mismatch can create collisions and poor performance. It is not a direct remedy for the condition described.

Question 246

An OSPF stub area accidentally receives external LSAs. Which change most directly meets this campus requirement?

Apply the intended stub-area design consistently on peers.
Configure supported ECMP behavior and equal metrics for eligible paths.
Configure appropriate area or external route summarization.
Apply inbound prefix-lists or route-maps with explicit allow policy.

Explanation

Correct Answer

Stub-area properties constrain external route advertisement. The engineer should apply the intended stub-area design consistently on peers.

Incorrect Answers

Equal-cost eligible next hops can be installed for load distribution. It is not a direct remedy for the condition described.

Summarization reduces route entries and update churn where topology permits. It is not a direct remedy for the condition described.

Inbound filtering controls which neighbor routes are accepted. It is not a direct remedy for the condition described.

Question 247

A campus access port should authenticate devices before granting production access. Which change most directly meets this campus requirement?

Use EAP-TLS with a trusted RADIUS certificate chain.
Enable 802.1X with authorized RADIUS and an appropriate fallback policy.
Use supported MACsec with authenticated keys and compatible peers.
Use DHCP snooping with correctly designated trust boundaries.

Explanation

Correct Answer

Port access control restricts network membership to authenticated endpoints. The engineer should enable 802.1X with authorized RADIUS and an appropriate fallback policy.

Incorrect Answers

EAP-TLS authenticates endpoints using public-key certificates. It is not a direct remedy for the condition described.

MACsec protects selected Ethernet frames at Layer 2. It is not a direct remedy for the condition described.

DHCP snooping can block server responses on untrusted access links. It is not a direct remedy for the condition described.

Question 248

A network team reports the following condition: A WLAN supports WPA3-Personal and must avoid shared-key downgrade. Select the most appropriate response.

Use WPA3-SAE with compatible client support.
Treat neighbor reports as assistance, not a guaranteed steering command.
Check WLAN group/AP assignment and radio/SSID enablement.
Enable protected management frames on compatible client SSIDs.

Explanation

Correct Answer

SAE provides password-based authenticated key exchange without legacy WPA2-PSK semantics. The engineer should use WPA3-SAE with compatible client support.

Incorrect Answers

802.11k supplies radio neighbor information while clients decide how to use it. It is not a direct remedy for the condition described.

Defining an SSID centrally does not prove each AP advertises it. It is not a direct remedy for the condition described.

PMF protects specific robust management frames from unauthenticated spoofing. It is not a direct remedy for the condition described.

Question 249

Following a campus change for this issue—two AOS-CX core peers require active downstream multichassis link aggregation—which result most directly verifies that the remedy works?

Test the keepalive source/peer connectivity and show VSX status.
Observe one logical LACP neighbor bundle spanning both paths.
Verify VSX peer health and downstream LAG member distribution.
Disconnect one member and confirm remaining bundle throughput.

Explanation

Correct Answer

VSX coordinates two switches to provide multi-chassis LAG forwarding. Verify VSX peer health and downstream LAG member distribution directly tests the desired behavior.

Incorrect Answers

VSX keepalive is a separate liveness mechanism from the ISL. That observation tests a different condition, not the required result.

Multichassis aggregation depends on coordinated LAG identity at the peer pair. That observation tests a different condition, not the required result.

LACP aggregation can survive individual member loss. That observation tests a different condition, not the required result.

Question 250

After completing the planned work for this situation—an AP uses a tagged management VLAN but the switch sends it untagged—how should success be checked?

Power on a representative unit and trace automatic policy assignment.
Resolve a known management FQDN from the device's management network.
Capture the first management exchange and inspect uplink VLAN settings.
Inspect transceiver diagnostics and both ends' interface state.

Explanation

Correct Answer

AP management requires consistent tagged versus untagged treatment. Capture the first management exchange and inspect uplink VLAN settings directly tests the desired behavior.

Incorrect Answers

Preprovisioning moves repeatable configuration into central management. That observation tests a different condition, not the required result.

Control-plane enrollment can fail when hostnames cannot resolve correctly. That observation tests a different condition, not the required result.

Physical link-up requires matching media and supported transceiver properties. That observation tests a different condition, not the required result.
