HP HPE7-A01 Practice Test 1

Question 1

During campus implementation, an access interface has an unexpected MAC move during 802.1X reauthentication. What should the engineer configure or correct?

Examine errdisable or protection events before re-enabling.
Align supported MTU across the required link path.
Correlate port-access session, device role and MAC table update.
Check SVI line state and operational VLAN membership.

Explanation

Correct Answer

Dynamic access policy can change VLAN/role while a client reconnects. The engineer should correlate port-access session, device role and MAC table update.

Incorrect Answers

An automatic protection feature may be intentionally shutting the port. It is not a direct remedy for the condition described.

Oversized frames can be dropped when intermediate L2 links have smaller MTU. It is not a direct remedy for the condition described.

An SVI may depend on its VLAN being operationally active. It is not a direct remedy for the condition described.

Question 2

A technician has applied this fix: Verify physical media, transceiver type and optical signal before routing. Which observation would provide the strongest acceptance evidence?

Inspect optic diagnostics and both ends' link state.
Compare MAC tables and port-security logs.
Capture DHCP DORA and inspect client VLAN.
Test the affected user certificate against a known-good endpoint.

Explanation

Correct Answer

Layer 1 failure must be resolved before Layer 3 diagnosis. Inspect optic diagnostics and both ends' link state directly tests the desired behavior.

Incorrect Answers

Layer 2 forwarding depends on learned destination MAC and permitted ports. That observation tests a different condition, not the required result.

Association and authentication are separate from address assignment. That observation tests a different condition, not the required result.

Per-endpoint authentication problems are not necessarily switch-wide faults. That observation tests a different condition, not the required result.

Question 3

A network team reports the following condition: A MAC-based printer moves to a different access switch but is assigned a generic user role. Select the most appropriate response.

Configure 802.1X EAP-TLS with a trusted RADIUS authorization response.
Repair RADIUS server address, VRF route or server group configuration.
Ensure endpoint profiling/group mapping is applied consistently.
Choose client-mode authentication rather than one-device blanket authorization.

Explanation

Correct Answer

Device category and enforcement mapping must follow endpoint identity across locations. The engineer should ensure endpoint profiling/group mapping is applied consistently.

Incorrect Answers

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

EAPOL client traffic still needs the authenticator to reach RADIUS. It is not a direct remedy for the condition described.

Client-mode authenticates connected clients individually where supported. It is not a direct remedy for the condition described.

Question 4

The campus team is closing a service ticket about this condition: One end of a LAG initiates while the other is passive. Which validation step is most relevant?

Capture LACP PDUs and verify both interfaces are in one bundle.
Compare MSTP digest and instance-to-VLAN tables on both switches.
Send a controlled unauthorized RA and verify it is not learned.
Inject a controlled BPDU and review protection event and port state.

Explanation

Correct Answer

Active mode initiates LACP negotiations that passive mode answers. Capture LACP PDUs and verify both interfaces are in one bundle directly tests the desired behavior.

Incorrect Answers

MSTP region agreement is required for consistent internal topology calculation. That observation tests a different condition, not the required result.

RA Guard filters unauthorized IPv6 router announcements. That observation tests a different condition, not the required result.

BPDU protection can isolate ports that violate the expected edge role. That observation tests a different condition, not the required result.

Question 5

A technician has applied this fix: Make user-facing OSPF interfaces passive while advertising the prefix. Which observation would provide the strongest acceptance evidence?

Verify the expected NSSA route and translated advertisement.
Inspect DR and BDR identities after a controlled election.
Inspect route-based tunnel IPs and OSPF neighbor state.
Verify no user-port hellos and continued prefix advertisement.

Explanation

Correct Answer

Passive OSPF suppresses adjacency exchange on the selected interface. Verify no user-port hellos and continued prefix advertisement directly tests the desired behavior.

Incorrect Answers

NSSA permits controlled local external redistribution in a stub-like area. That observation tests a different condition, not the required result.

DR election considers priority before router-ID tiebreaking. That observation tests a different condition, not the required result.

VPN tunnel establishment does not itself form a routing adjacency. That observation tests a different condition, not the required result.

Question 6

A network team reports the following condition: Large OSPF networks have oversized summary routes at the distribution boundary. Select the most appropriate response.

Compare local preference, AS path and other best-path criteria.
Enable compatible OSPF participation on the proper L3 interfaces.
Apply redistribution with explicit route maps or permitted prefixes.
Configure appropriate area or external route summarization.

Explanation

Correct Answer

Summarization reduces route entries and update churn where topology permits. The engineer should configure appropriate area or external route summarization.

Incorrect Answers

BGP attributes determine preference beyond ordinary hop count. It is not a direct remedy for the condition described.

VPN tunnel establishment does not itself form a routing adjacency. It is not a direct remedy for the condition described.

Unfiltered redistribution can advertise unintended internal routes. It is not a direct remedy for the condition described.

Question 7

The campus team is closing a service ticket about this condition: Wi-Fi 6 clients have poor throughput during crowded OFDMA periods. Which validation step is most relevant?

Compare queue depth and latency during a backup transfer.
Compare AP channel maps, channel busy time and retries.
Compare RTP jitter with queue occupancy after tuning.
Compare HE capability and airtime resource-unit statistics.

Explanation

Correct Answer

OFDMA benefits depend on both AP and client support and actual traffic mix. Compare HE capability and airtime resource-unit statistics directly tests the desired behavior.

Incorrect Answers

Long egress queues create delay and jitter under sustained overload. That observation tests a different condition, not the required result.

Co-channel interference causes shared airtime contention. That observation tests a different condition, not the required result.

Full link saturation exposes serialization and queuing delays. That observation tests a different condition, not the required result.

Question 8

After completing the planned work for this situation—a WLAN drops new associations during a temporary DHCP outage—how should success be checked?

Capture DHCP packets after the successful association event.
Correlate retry rate with noise floor and other transmitters.
Monitor roam RSSI and handoff delay in the hallway.
Compare airtime share and goodput by client PHY rate.

Explanation

Correct Answer

Successful association does not guarantee an IPv4 address. Capture DHCP packets after the successful association event directly tests the desired behavior.

Incorrect Answers

RSSI alone cannot identify noise or contention-driven retries. That observation tests a different condition, not the required result.

Excess cell reach and very low data rates can promote sticky clients. That observation tests a different condition, not the required result.

A slow client can occupy much airtime for comparatively few bytes. That observation tests a different condition, not the required result.

Question 9

A technician has applied this fix: Export a supported backup or checkpoint and record rollback steps. Which observation would provide the strongest acceptance evidence?

Compare the audit diff with the device's active configuration.
Restore in a test environment and compare intended interfaces/policies.
Check installed versus intended version after controlled reboot.
Inspect denied command logs and agent rule execution.

Explanation

Correct Answer

Recovery requires a known-good configuration and compatible restore method. Restore in a test environment and compare intended interfaces/policies directly tests the desired behavior.

Incorrect Answers

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

Version management requires appropriate platform images and maintenance windows. That observation tests a different condition, not the required result.

NAE operations may be constrained by command authorization. That observation tests a different condition, not the required result.

Question 10

The engineer reports completing this change: Choose client-mode authentication rather than one-device blanket authorization. Which verification should be included in the handover?

Compare reject-role and critical-role results in a controlled test.
Connect a second unauthorized endpoint and verify it stays isolated.
Inspect server logs for authenticator failures and retest.
Inspect supplicant TLS alert and server-name validation.

Explanation

Correct Answer

Client-mode authenticates connected clients individually where supported. Connect a second unauthorized endpoint and verify it stays isolated directly tests the desired behavior.

Incorrect Answers

An explicit Access-Reject differs from a server communication failure. That observation tests a different condition, not the required result.

RADIUS integrity checks depend on matching shared secrets. That observation tests a different condition, not the required result.

Supplicants may reject a server even when its signing CA is trusted. That observation tests a different condition, not the required result.
