HP HPE7-A01 Practice Test 3

Question 20

A network team reports the following condition: A corporate wireless SSID needs unique credentials per user rather than one PSK. Select the most appropriate response.

Enforce supported port-security violation behavior.
Deploy enterprise 802.1X and suitable RADIUS policy.
Apply quarantine/deny role based on verified endpoint status.
Apply an explicit allowlist policy and deny all other flows.

Explanation

Correct Answer

Central identity policy allows per-user accountability and revocation. The engineer should deploy enterprise 802.1X and suitable RADIUS policy.

Incorrect Answers

Port security prevents arbitrary new MAC addresses from gaining access. It is not a direct remedy for the condition described.

Enforcement should follow authenticated context rather than an unverified MAC alone. It is not a direct remedy for the condition described.

Least privilege limits permitted applications to approved business needs. It is not a direct remedy for the condition described.

Question 21

During campus implementation, a switch uplink LAG shows one member not collecting or distributing. What should the engineer configure or correct?

Check the relevant root-guard role on that uplink.
Enable supported dynamic ARP inspection using valid bindings.
Enable an appropriate STP edge-port setting with protection.
Inspect LACP synchronization and speed/duplex compatibility.

Explanation

Correct Answer

All participating LAG members must negotiate compatible operation. The engineer should inspect LACP synchronization and speed/duplex compatibility.

Incorrect Answers

Root guard prevents an unplanned switch from taking over the root position. It is not a direct remedy for the condition described.

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

Edge semantics reduce startup delay but should not blindly trust bridge devices. It is not a direct remedy for the condition described.

Question 22

During campus implementation, a wireless user enters correct credentials but authorization policy denies access. What should the engineer configure or correct?

Separate EAP authentication success from policy-enforcement rejection.
Configure supported voice/data or multi-domain port authentication.
Correct certificate identity and RADIUS mapping policy.
Configure supported TACACS+/RBAC command authorization.

Explanation

Correct Answer

A successful identity check does not automatically grant every role. The engineer should separate EAP authentication success from policy-enforcement rejection.

Incorrect Answers

Phone and data station may require separate access identities and roles. It is not a direct remedy for the condition described.

Authorization must map the authenticated certificate identity to the intended user/device. It is not a direct remedy for the condition described.

Authentication identifies administrators; authorization controls permitted commands. It is not a direct remedy for the condition described.

Question 23

The campus team is closing a service ticket about this condition: A client receives high RSSI but its uplink stalls. Which validation step is most relevant?

Compare HE capability and airtime resource-unit statistics.
Send a test packet with false priority and inspect egress marking.
Repeat the same test plan and compare normalized metrics.
Measure uplink RSSI/SNR at AP and retry counters.

Explanation

Correct Answer

AP downlink power may exceed handheld uplink capability. Measure uplink RSSI/SNR at AP and retry counters directly tests the desired behavior.

Incorrect Answers

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

QoS trust should be granted to known sources, not arbitrary clients. That observation tests a different condition, not the required result.

Optimization requires a measured baseline to distinguish improvement from noise. That observation tests a different condition, not the required result.

Question 24

The engineer reports completing this change: Check DNS resolver assignment and reachability. Which verification should be included in the handover?

Compare DNS lookup with direct IP connectivity.
Capture the roam time line and RTP loss at each stage.
Perform a peak-hour RF survey and a quiet-hour comparison.
Compare MAC tables and port-security logs.

Explanation

Correct Answer

Name-resolution failure can resemble a general network outage. Compare DNS lookup with direct IP connectivity directly tests the desired behavior.

Incorrect Answers

Fast RF association and data-plane continuity are different measures. 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.

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

Question 25

After completing the planned work for this situation—a campus bridge has a broadcast storm after a patch-cable mistake—how should success be checked?

Compare egress queue drops and utilization during a load test.
Send a controlled unauthorized RA and verify it is not learned.
Connect an unregistered test device and inspect the violation action.
Compare ingress broadcast rate before and after a controlled storm fixture.

Explanation

Correct Answer

Storm control limits excess broadcast or multicast traffic while loops are fixed. Compare ingress broadcast rate before and after a controlled storm fixture directly tests the desired behavior.

Incorrect Answers

Output drops can arise from queue pressure even without physical corruption. 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.

Port security restricts which endpoint MAC addresses can use the link. That observation tests a different condition, not the required result.

Question 26

A network team reports the following condition: A Wi-Fi client reports association failure before acquiring an IP address. Select the most appropriate response.

Match the AP power requirement with a supported 802.3af/at/bt PoE budget.
Check 802.11 authentication and association management frames before DHCP.
Use 802.11 contention and collision-avoidance planning rather than Ethernet full-duplex assumptions.
Check Neighbor Discovery messages and router advertisements rather than ARP.

Explanation

Correct Answer

Wi-Fi management frames establish the radio connection before IP-layer onboarding. The engineer should check 802.11 authentication and association management frames before DHCP.

Incorrect Answers

PoE classes and available per-port power affect whether an AP can enable full capability. It is not a direct remedy for the condition described.

802.11 stations contend for shared airtime, so carrier-sense and backoff affect throughput. It is not a direct remedy for the condition described.

IPv6 uses ICMPv6 Neighbor Discovery for neighbor and router discovery. It is not a direct remedy for the condition described.

Question 27

For an HPE Aruba Networking campus deployment, a WLAN configured for a specific VLAN gives clients a different address range. Which action best addresses it?

Treat neighbor reports as assistance, not a guaranteed steering command.
Verify client DNS option, resolver reachability and suffix.
Distinguish the AP control path from client forwarding and VLAN policy.
Inspect SSID-to-VLAN mapping and downstream trunk availability.

Explanation

Correct Answer

Client IP assignment follows the effective user VLAN and DHCP scope. The engineer should inspect SSID-to-VLAN mapping and downstream trunk availability.

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.

DNS failure can appear as WLAN failure despite correct radio and IP connectivity. It is not a direct remedy for the condition described.

Management connectivity does not automatically grant data-plane reachability. It is not a direct remedy for the condition described.

Question 28

A routed SVI is configured but its VLAN has no active member ports. Which change most directly meets this campus requirement?

Set intentional root priorities and protect upstream ports.
Check SVI line state and operational VLAN membership.
Enable DHCP snooping with uplinks designated as trusted.
Keep one LACP side active and the peer interoperable.

Explanation

Correct Answer

An SVI may depend on its VLAN being operationally active. The engineer should check SVI line state and operational VLAN membership.

Incorrect Answers

Spanning-tree root selection must reflect the planned campus topology. It is not a direct remedy for the condition described.

DHCP snooping blocks unauthorized server replies on untrusted ports. It is not a direct remedy for the condition described.

Active mode initiates LACP negotiations that passive mode answers. It is not a direct remedy for the condition described.

Question 29

Following a campus change for this issue—a core switch needs a route to an offsite network not directly connected—which result most directly verifies that the remedy works?

Look up the route and ping the next hop from the right VRF.
Verify the expected NSSA route and translated advertisement.
Capture hello packets and verify consistent timers.
Compare chosen next hop for two addresses in different prefix lengths.

Explanation

Correct Answer

Static forwarding requires the destination prefix and next-hop resolution. Look up the route and ping the next hop from the right VRF 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.

Neighbor timer compatibility matters for OSPF adjacency formation. That observation tests a different condition, not the required result.

More-specific prefixes normally override less-specific matches in route lookup. That observation tests a different condition, not the required result.

Question 30

A network team reports the following condition: Two redundant distribution switches map VLANs to different MSTP instance IDs. Select the most appropriate response.

Find the source of MAC flapping or a Layer 2 loop.
Enable supported dynamic ARP inspection using valid bindings.
Inspect LLDP-MED voice policy and endpoint support.
Match region name, revision and VLAN-instance mappings.

Explanation

Correct Answer

MSTP region agreement is required for consistent internal topology calculation. The engineer should match region name, revision and VLAN-instance mappings.

Incorrect Answers

Rapid MAC moves may indicate a loop, duplicated host or roaming bridge. It is not a direct remedy for the condition described.

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

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