HP HPE7-A01 Practice Test 11

Question 100

The campus team is closing a service ticket about this condition: A switch forwards traffic in the wrong VLAN after a trunk reconfiguration. Which validation step is most relevant?

Send incrementing frame sizes and read giant/discard counters.
Capture VLAN tags across the trunk and verify endpoint membership.
Try permitted and denied management connections from test hosts.
Generate mixed voice/data loads and inspect queue-specific drops.

Explanation

Correct Answer

VLAN classification on ingress determines Layer 2 forwarding and segmentation. Capture VLAN tags across the trunk and verify endpoint membership directly tests the desired behavior.

Incorrect Answers

Oversized frames can be dropped when intermediate L2 links have smaller MTU. That observation tests a different condition, not the required result.

Administrative access protection is distinct from normal endpoint forwarding. That observation tests a different condition, not the required result.

QoS classification and queue maps control congestion behavior. That observation tests a different condition, not the required result.

Question 101

A technician has applied this fix: Keep healthy LAG members forwarding while removing the failed link. Which observation would provide the strongest acceptance evidence?

Disconnect one member and confirm remaining bundle throughput.
Confirm the expected alternate port blocks and broadcast counts remain stable.
Isolate management reachability and test existing client data flow.
Remove primary reachability and confirm route replacement.

Explanation

Correct Answer

LACP aggregation can survive individual member loss. Disconnect one member and confirm remaining bundle throughput directly tests the desired behavior.

Incorrect Answers

Loop prevention protects bridged domains from uncontrolled circulation. That observation tests a different condition, not the required result.

Management-plane loss should be evaluated separately from the user forwarding path. That observation tests a different condition, not the required result.

Redundancy requires more than an unused physical interface. That observation tests a different condition, not the required result.

Question 102

An engineer is planning corrective work because two client classes compete for limited WLAN airtime. Which step should be prioritized?

Set suitable minimum data rates after validating coverage.
Review channel reuse and power plan using a measured survey.
Calibrate cell-edge target and neighboring AP power.
Consider supported airtime fairness and data-rate policy.

Explanation

Correct Answer

Equal byte throughput is not the same as equal shared radio airtime. The engineer should consider supported airtime fairness and data-rate policy.

Incorrect Answers

Low PHY rates consume more airtime for each transmitted byte. It is not a direct remedy for the condition described.

Co-channel interference causes shared airtime contention. It is not a direct remedy for the condition described.

Excess power can delay client roaming despite good RSSI. It is not a direct remedy for the condition described.

Question 103

Following a campus change for this issue—a multicast video service floods every port in the VLAN—which result most directly verifies that the remedy works?

Join and leave a test group and observe forwarding-port membership.
Compare neighbor chassis/port IDs with the patching schedule.
Swap a known-good cable and compare physical error counters.
Compare per-port drawn/allocated power with remaining switch capacity.

Explanation

Correct Answer

IGMP snooping limits eligible multicast delivery to interested ports. Join and leave a test group and observe forwarding-port membership directly tests the desired behavior.

Incorrect Answers

LLDP advertises directly connected device identity and capabilities. That observation tests a different condition, not the required result.

Frame check errors usually indicate problems below the IP layer. That observation tests a different condition, not the required result.

Power budget decisions determine which powered endpoints receive sufficient wattage. That observation tests a different condition, not the required result.

Question 104

Following a campus change for this issue—a device requires multiple OSPF routes to carry equal-cost flows—which result most directly verifies that the remedy works?

Inspect route-based tunnel IPs and OSPF neighbor state.
Check the forwarding table for multiple next hops.
Advertise a client route and verify another client learns it.
Check inbound versus advertised route attributes after attachment.

Explanation

Correct Answer

Equal-cost eligible next hops can be installed for load distribution. Check the forwarding table for multiple next hops directly tests the desired behavior.

Incorrect Answers

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

Route reflection reduces the iBGP full-mesh requirement. That observation tests a different condition, not the required result.

Import and export policy have different control-plane effects. That observation tests a different condition, not the required result.

Question 105

Following a campus change for this issue—a voice SSID uses the lowest legacy basic rate for all frames—which result most directly verifies that the remedy works?

Match spectrum captures with the machine's operating cycle.
Compare management-frame airtime and edge coverage after a cautious rate change.
Confirm users receive differentiated roles on a shared WLAN.
Inspect neighbor-report responses during a controlled roam.

Explanation

Correct Answer

Very low basic rates consume disproportionate airtime. Compare management-frame airtime and edge coverage after a cautious rate change directly tests the desired behavior.

Incorrect Answers

An intermittent interferer can explain periodic retries without any configuration change. That observation tests a different condition, not the required result.

Distinct policy does not always require a new beaconing SSID. That observation tests a different condition, not the required result.

Neighbor reports can reduce the amount of blind scanning needed. That observation tests a different condition, not the required result.

Question 106

A network team reports the following condition: A switch should relay DHCP for clients in a remote server subnet. Select the most appropriate response.

Check platform ECMP settings and route eligibility.
Inspect FIB installation and persistent session forwarding state.
Correct incompatible interface MTU or documented OSPF handling.
Configure DHCP relay/helper on the appropriate routed interface.

Explanation

Correct Answer

DHCP broadcasts require relay when the server is beyond a router. The engineer should configure DHCP relay/helper on the appropriate routed interface.

Incorrect Answers

Multiple configured next hops do not guarantee equal-cost installation. It is not a direct remedy for the condition described.

Control-plane route updates and existing session datapaths can differ. It is not a direct remedy for the condition described.

Database description exchange can fail when MTU expectations differ. It is not a direct remedy for the condition described.

Question 107

For an HPE Aruba Networking campus deployment, an IPv6 host can reach its same-link neighbor but not remote prefixes. Which action best addresses it?

Configure a static route with a reachable next hop in the correct VRF.
Put customer routes in separate VRFs with controlled leaking where authorized.
Verify IPv6 default route and next-hop neighbor discovery.
Compare the exact prefix, mask and next-hop resolution on both ends.

Explanation

Correct Answer

Link-local reachability does not guarantee routed IPv6 connectivity. The engineer should verify IPv6 default route and next-hop neighbor discovery.

Incorrect Answers

Static forwarding requires the destination prefix and next-hop resolution. It is not a direct remedy for the condition described.

VRFs maintain independent route tables and overlapping address space. It is not a direct remedy for the condition described.

A less-specific summary can mask an absent needed route. It is not a direct remedy for the condition described.

Question 108

The campus team is closing a service ticket about this condition: A WLAN receives spoofed disconnect frames from an adjacent attacker. Which validation step is most relevant?

Disable one user account and confirm other users remain authorized.
Capture the wire and confirm payload confidentiality on the chosen path.
Trigger an authorized posture change and observe new role permissions.
Verify PMF negotiated and controlled spoofed disconnect is rejected.

Explanation

Correct Answer

Protected management frames prevent unauthenticated robust management manipulation. Verify PMF negotiated and controlled spoofed disconnect is rejected directly tests the desired behavior.

Incorrect Answers

Central identity policy allows per-user accountability and revocation. That observation tests a different condition, not the required result.

Encryption choice depends on Layer 2 versus application-layer trust boundaries. That observation tests a different condition, not the required result.

Dynamic authorization must reflect changing endpoint trust. That observation tests a different condition, not the required result.

Question 109

After completing the planned work for this situation—an intermittent application failure needs packet-level proof—how should success be checked?

Compare MAC tables and port-security logs.
Perform a peak-hour RF survey and a quiet-hour comparison.
Inspect the request/response exchange during failure.
Compare an affected and unaffected endpoint on the same path.

Explanation

Correct Answer

Packet capture distinguishes transport retransmissions, resets and filtering. Inspect the request/response exchange during failure 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.

Time-correlated environmental changes can explain periodic performance drops. That observation tests a different condition, not the required result.

Fault isolation starts by defining the smallest affected domain. That observation tests a different condition, not the required result.

Question 110

A technician has applied this fix: Use scoped certificate-level controls without unauthorized TLS payload inspection. Which observation would provide the strongest acceptance evidence?

Confirm users receive differentiated roles on a shared WLAN.
Record channel utilization and per-client retries at peak attendance.
Map RSSI overlap and co-channel busy time after changes.
Confirm the guest policy is enforced without examining private page bodies.

Explanation

Correct Answer

Certificate visibility and full decryption have different privacy implications. Confirm the guest policy is enforced without examining private page bodies directly tests the desired behavior.

Incorrect Answers

Distinct policy does not always require a new beaconing SSID. That observation tests a different condition, not the required result.

Strong signal alone does not guarantee available airtime. That observation tests a different condition, not the required result.

Cell overlap depends on EIRP, antenna pattern and building attenuation. That observation tests a different condition, not the required result.
