HP HPE7-A01 Practice Test 43

Question 420

During campus implementation, an endpoint is reachable from one switch but not another in the same VLAN. What should the engineer configure or correct?

Diff the current state against the last known-good configuration.
Check TCP port 179, source address and remote AS settings.
Inspect EAP/TLS trust and expiration before changing WLAN channels.
Inspect MAC table learning and potential port-security blocking.

Explanation

Correct Answer

Layer 2 forwarding depends on learned destination MAC and permitted ports. The engineer should inspect MAC table learning and potential port-security blocking.

Incorrect Answers

Change correlation narrows likely causes without assuming every recent edit is wrong. It is not a direct remedy for the condition described.

IP reachability alone does not establish BGP session negotiation. It is not a direct remedy for the condition described.

Certificate validation occurs after the client discovers the SSID. It is not a direct remedy for the condition described.

Question 421

A technician has applied this fix: Inspect MAC table learning and potential port-security blocking. Which observation would provide the strongest acceptance evidence?

Capture TCP SYN and BGP OPEN exchanges.
Compare MAC tables and port-security logs.
Revert one safe test change and verify incident symptoms.
Compare RADIUS/supplicant TLS errors for failing clients.

Explanation

Correct Answer

Layer 2 forwarding depends on learned destination MAC and permitted ports. Compare MAC tables and port-security logs directly tests the desired behavior.

Incorrect Answers

IP reachability alone does not establish BGP session negotiation. That observation tests a different condition, not the required result.

Change correlation narrows likely causes without assuming every recent edit is wrong. That observation tests a different condition, not the required result.

Certificate validation occurs after the client discovers the SSID. That observation tests a different condition, not the required result.

Question 422

The campus team is closing a service ticket about this condition: An IPsec overlay needs OSPF routes across a routed tunnel. Which validation step is most relevant?

Compare neighbor configuration with received OPEN notifications.
Inspect IPv6 route table and NDP resolution for next hop.
Inspect route-based tunnel IPs and OSPF neighbor state.
Compare intended and actual advertised prefix lists.

Explanation

Correct Answer

VPN tunnel establishment does not itself form a routing adjacency. Inspect route-based tunnel IPs and OSPF neighbor state directly tests the desired behavior.

Incorrect Answers

BGP OPEN negotiation checks peer AS compatibility. That observation tests a different condition, not the required result.

Link-local reachability does not guarantee routed IPv6 connectivity. That observation tests a different condition, not the required result.

Outbound routing policies control which local routes are advertised. That observation tests a different condition, not the required result.

Question 423

For an HPE Aruba Networking campus deployment, an IPv6 access segment receives a rogue router advertisement. Which action best addresses it?

Inspect LLDP-MED voice policy and endpoint support.
Use a supported RA Guard policy on untrusted access ports.
Trust only approved voice marking and map traffic to suitable egress queues.
Enable appropriate IGMP snooping and confirm listener groups.

Explanation

Correct Answer

RA Guard filters unauthorized IPv6 router announcements. The engineer should use a supported RA Guard policy on untrusted access ports.

Incorrect Answers

LLDP-MED can communicate voice VLAN and QoS settings to phones. It is not a direct remedy for the condition described.

QoS classification and queue maps control congestion behavior. 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.

Question 424

An engineer is planning corrective work because an endpoint should be denied after its certificate is revoked. Which step should be prioritized?

Use MAC-based authentication with a restricted printer role.
Separate EAP authentication success from policy-enforcement rejection.
Ensure certificate revocation checking is enforced where applicable.
Configure 802.1X EAP-TLS with a trusted RADIUS authorization response.

Explanation

Correct Answer

A valid-looking certificate may no longer be authorized after revocation. The engineer should ensure certificate revocation checking is enforced where applicable.

Incorrect Answers

MAB can accommodate legacy devices but offers weaker identity assurance. It is not a direct remedy for the condition described.

A successful identity check does not automatically grant every role. It is not a direct remedy for the condition described.

EAP-TLS validates certificate identity and central policy chooses the access role. It is not a direct remedy for the condition described.

Question 425

For an HPE Aruba Networking campus deployment, an OSPF broadcast segment needs a planned DR. Which action best addresses it?

Apply the intended stub-area design consistently on peers.
Configure deliberate default origination with correct conditions.
Correct the neighbor remote AS and intended eBGP/iBGP relationship.
Set appropriate OSPF interface priority where supported.

Explanation

Correct Answer

DR election considers priority before router-ID tiebreaking. The engineer should set appropriate OSPF interface priority where supported.

Incorrect Answers

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

OSPF does not automatically inject a default solely because WAN exists. It is not a direct remedy for the condition described.

BGP OPEN negotiation checks peer AS compatibility. It is not a direct remedy for the condition described.

Question 426

During campus implementation, a switch stack joins with inconsistent software versions. What should the engineer configure or correct?

Make the AP uplink native/tagged VLAN expectation match the switch port.
Align supported member images and the stack compatibility requirements.
Negotiate or explicitly align supported speed and duplex settings.
Align the LACP actor/partner mode and member compatibility.

Explanation

Correct Answer

Stack membership commonly requires compatible software and platform capabilities. The engineer should align supported member images and the stack compatibility requirements.

Incorrect Answers

AP management requires consistent tagged versus untagged treatment. 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.

A LAG requires compatible peer negotiation and member parameters. It is not a direct remedy for the condition described.

Question 427

After completing the planned work for this situation—a UXI sensor reports poor cloud SaaS health but Wi-Fi RSSI looks good—how should success be checked?

Attempt a supported lab configuration and review feature conflict status.
Compare synthetic latency, packet loss and client radio metrics.
Compare the audit diff with the device's active configuration.
Verify NTP synchronization and correlate a known test event.

Explanation

Correct Answer

Good RSSI does not prove application-path quality. Compare synthetic latency, packet loss and client radio metrics directly tests the desired behavior.

Incorrect Answers

Some platform/release combinations limit simultaneous capture features. That observation tests a different condition, not the required result.

Configuration intent and installed running state must be compared. That observation tests a different condition, not the required result.

Cross-device troubleshooting depends on aligned timestamps and measurements. That observation tests a different condition, not the required result.

Question 428

A network team reports the following condition: OSPF routes prefer the wrong uplink for critical services. Select the most appropriate response.

Ensure area border routing is planned and configured correctly.
Configure appropriate area or external route summarization.
Tune supported interface costs consistently with the topology.
Check source/peer reachability and transport before BGP attributes.

Explanation

Correct Answer

OSPF SPF uses accumulated interface metrics for path selection. The engineer should tune supported interface costs consistently with the topology.

Incorrect Answers

An ABR connects area 0 with additional OSPF areas. 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.

BGP uses a TCP session and requires reachable configured neighbors. It is not a direct remedy for the condition described.

Question 429

During campus implementation, a 6 GHz client sees the SSID only after a long scan. What should the engineer configure or correct?

Deploy EAP-TLS through supported RADIUS policy with trusted certificates.
Review preferred scanning channel and discovery configuration.
Apply client isolation or appropriate role-based segmentation.
Evaluate supported 802.11r fast-transition configuration and client compatibility.

Explanation

Correct Answer

6 GHz discovery procedures differ from legacy 2.4/5 GHz behavior. The engineer should review preferred scanning channel and discovery configuration.

Incorrect Answers

EAP-TLS uses certificate authentication and requires valid trust chains. It is not a direct remedy for the condition described.

Guest devices should not gain unnecessary direct peer reachability. It is not a direct remedy for the condition described.

Fast transition can reduce reassociation authentication overhead. It is not a direct remedy for the condition described.

Question 430

A network team reports the following condition: A trunk carries several departments over one physical Ethernet connection. Select the most appropriate response.

Trace EAPOL between client and switch and RADIUS between switch and server.
Check 802.11 authentication and association management frames before DHCP.
Investigate errors, drops and congestion rather than expecting Ethernet CSMA/CD collisions.
Use 802.1Q VLAN tags to preserve the correct broadcast domains.

Explanation

Correct Answer

VLAN tags identify individual logical Layer 2 networks on a shared trunk. The engineer should use 802.1Q VLAN tags to preserve the correct broadcast domains.

Incorrect Answers

EAPOL is used at the endpoint edge while the authenticator relays authentication over RADIUS. It is not a direct remedy for the condition described.

Wi-Fi management frames establish the radio connection before IP-layer onboarding. It is not a direct remedy for the condition described.

Modern switched full-duplex Ethernet does not use half-duplex collision detection. It is not a direct remedy for the condition described.
