HP HPE7-A01 Practice Test 13

Question 120

The engineer reports completing this change: Apply an explicit allowlist policy and deny all other flows. Which verification should be included in the handover?

Inject high-marked guest traffic and observe effective egress class.
Simulate RADIUS outage and observe the assigned critical role.
Test a permitted and denied service with policy-hit evidence.
Send a forged test ARP and inspect rejection logs.

Explanation

Correct Answer

Least privilege limits permitted applications to approved business needs. Test a permitted and denied service with policy-hit evidence directly tests the desired behavior.

Incorrect Answers

Untrusted clients can self-mark traffic to obtain an undeserved priority. 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.

Dynamic ARP inspection validates address/MAC claims on untrusted ports. That observation tests a different condition, not the required result.

Question 121

An external provider advertises a default route that should not override internal policy. Which change most directly meets this campus requirement?

Choose the intended preferred route distance for failover policy.
Inspect FIB installation and persistent session forwarding state.
Filter or lower preference for the received default route.
Tune supported interface costs consistently with the topology.

Explanation

Correct Answer

Route import policy can protect internal next-hop expectations. The engineer should filter or lower preference for the received default route.

Incorrect Answers

Lower administrative distance normally wins among comparable route sources. 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.

OSPF SPF uses accumulated interface metrics for path selection. It is not a direct remedy for the condition described.

Question 122

Following a campus change for this issue—a campus fabric uses iBGP but cannot fully mesh every internal node—which result most directly verifies that the remedy works?

Advertise a client route and verify another client learns it.
Trace a matching and nonmatching flow and compare egress.
Compare intended and actual advertised prefix lists.
Test a planned restart and observe stale route lifecycle.

Explanation

Correct Answer

Route reflection reduces the iBGP full-mesh requirement. Advertise a client route and verify another client learns it directly tests the desired behavior.

Incorrect Answers

PBR can select forwarding based on match criteria beyond destination route. 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.

Graceful restart may preserve forwarding while control-plane updates recover. That observation tests a different condition, not the required result.

Question 123

The engineer reports completing this change: Source BGP from loopback and ensure loopback route reachability. Which verification should be included in the handover?

Capture RA and check host IPv6 route/address state.
Check inbound versus advertised route attributes after attachment.
Inspect received default and chosen route after policy evaluation.
Fail one transit and observe TCP and BGP session continuity.

Explanation

Correct Answer

Loopback sessions survive individual link changes when routed connectivity remains. Fail one transit and observe TCP and BGP session continuity directly tests the desired behavior.

Incorrect Answers

Router advertisements communicate default-router and prefix information. 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.

Route import policy can protect internal next-hop expectations. That observation tests a different condition, not the required result.

Question 124

A technician has applied this fix: Consolidate SSIDs when authorization roles can differentiate users. Which observation would provide the strongest acceptance evidence?

Generate voice and bulk traffic and measure jitter/queue drops.
Compare RTP jitter with queue occupancy after tuning.
Measure beacon airtime and capacity with fewer SSIDs.
Track per-station airtime and edge connectivity before/after adjustment.

Explanation

Correct Answer

More SSIDs increase beacon/management overhead. Measure beacon airtime and capacity with fewer SSIDs directly tests the desired behavior.

Incorrect Answers

QoS scheduling helps latency-sensitive packets compete under load. 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.

Low PHY rates consume more airtime for each transmitted byte. That observation tests a different condition, not the required result.

Question 125

Following a campus change for this issue—a client repeatedly receives EAP requests but never answers EAPOL—which result most directly verifies that the remedy works?

Inspect supplicant TLS alert and server-name validation.
Capture EAPOL-Request and absence/presence of EAPOL-Response.
Capture pre/post-login user role and policy hits.
Inspect certificate subject/SAN and RADIUS policy trace.

Explanation

Correct Answer

EAPOL exchange requires the endpoint to participate in authentication. Capture EAPOL-Request and absence/presence of EAPOL-Response directly tests the desired behavior.

Incorrect Answers

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

Portal success requires enforcement state to change before normal internet traffic. That observation tests a different condition, not the required result.

Authorization must map the authenticated certificate identity to the intended user/device. That observation tests a different condition, not the required result.

Question 126

Following a campus change for this issue—a guest SSID should show web onboarding before access—which result most directly verifies that the remedy works?

Capture beacon/SSID advertisement at the affected AP and compare group policy.
Associate a new test guest and inspect portal redirect and post-login role.
Compare channel changes and neighboring channel utilization after optimization.
Trace the client role, VLAN, gateway and policy path.

Explanation

Correct Answer

Captive portals add user onboarding beyond basic association. Associate a new test guest and inspect portal redirect and post-login role directly tests the desired behavior.

Incorrect Answers

Defining an SSID centrally does not prove each AP advertises it. That observation tests a different condition, not the required result.

Automatic RF optimization can adapt channel assignment to observed neighbors. That observation tests a different condition, not the required result.

Management connectivity does not automatically grant data-plane reachability. That observation tests a different condition, not the required result.

Question 127

The campus team is closing a service ticket about this condition: An attacker sends forged ARP replies on a user VLAN. Which validation step is most relevant?

Compare trusted and untrusted DHCPv6 advertisements in a test VLAN.
Compare forged and valid ARP replies and their inspection counters.
Compare neighbor chassis/port IDs with the patching schedule.
Test host-to-host and host-to-gateway reachability for each port role.

Explanation

Correct Answer

Dynamic ARP inspection can reject ARP packets inconsistent with trusted bindings. Compare forged and valid ARP replies and their inspection counters directly tests the desired behavior.

Incorrect Answers

DHCPv6 protection prevents unapproved address services from client ports. That observation tests a different condition, not the required result.

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

Private VLAN constructs isolate hosts within a shared IP subnet. That observation tests a different condition, not the required result.

Question 128

A technician has applied this fix: Verify neighbor assistance and actual roam trigger/timing. Which observation would provide the strongest acceptance evidence?

Compare channel changes and neighboring channel utilization after optimization.
Observe neighbor reports and actual roaming decisions.
Capture roam event timestamps and neighbor reports.
Compare uplink and downlink RSSI at edge locations.

Explanation

Correct Answer

802.11k/v can aid roaming decisions but client behavior still matters. Capture roam event timestamps and neighbor reports directly tests the desired behavior.

Incorrect Answers

Automatic RF optimization can adapt channel assignment to observed neighbors. That observation tests a different condition, not the required result.

802.11k supplies radio neighbor information while clients decide how to use it. That observation tests a different condition, not the required result.

Downlink coverage does not ensure the return path from low-power clients. That observation tests a different condition, not the required result.

Question 129

The campus team is closing a service ticket about this condition: A user signs into a guest portal but retains a pre-authentication role. Which validation step is most relevant?

Compare profiling result and effective role on both switches.
Inspect RADIUS attributes and the port's applied VLAN.
Attempt authentication with a revoked test certificate.
Capture pre/post-login user role and policy hits.

Explanation

Correct Answer

Portal success requires enforcement state to change before normal internet traffic. Capture pre/post-login user role and policy hits directly tests the desired behavior.

Incorrect Answers

Device category and enforcement mapping must follow endpoint identity across locations. That observation tests a different condition, not the required result.

Authentication success and assigned authorization policy are separate decisions. That observation tests a different condition, not the required result.

A valid-looking certificate may no longer be authorized after revocation. That observation tests a different condition, not the required result.

Question 130

A network team reports the following condition: An IPsec overlay needs OSPF routes across a routed tunnel. Select the most appropriate response.

Verify IPv6 default route and next-hop neighbor discovery.
Enable compatible OSPF participation on the proper L3 interfaces.
Correct the neighbor remote AS and intended eBGP/iBGP relationship.
Apply outbound prefix filtering and verify route policy direction.

Explanation

Correct Answer

VPN tunnel establishment does not itself form a routing adjacency. The engineer should enable compatible OSPF participation on the proper L3 interfaces.

Incorrect Answers

Link-local reachability does not guarantee routed IPv6 connectivity. 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.

Outbound routing policies control which local routes are advertised. It is not a direct remedy for the condition described.
