HP HPE7-A01 Practice Test 58

Question 570

For an HPE Aruba Networking campus deployment, a stack loses its management IP when the conductor fails. Which action best addresses it?

Use supported BFD where it is interoperable with the routing protocol.
Examine VRRP priorities, preemption and advertisement reachability.
Verify supported conductor/standby election and management continuity.
Ensure spanning tree or loop protection blocks the redundant path.

Explanation

Correct Answer

Stack control-plane failover is distinct from individual data-link forwarding. The engineer should verify supported conductor/standby election and management continuity.

Incorrect Answers

BFD provides fast liveliness information separate from normal route timers. It is not a direct remedy for the condition described.

Virtual-router election depends on priority and exchanged advertisements. It is not a direct remedy for the condition described.

Loop prevention protects bridged domains from uncontrolled circulation. It is not a direct remedy for the condition described.

Question 571

For an HPE Aruba Networking campus deployment, two access uplinks form an unintended Layer 2 loop. Which action best addresses it?

Build a supported VSX pair with matching VSX LAG configuration.
Feed redundant supplies from independent power sources.
Use supported ECMP next-hop installation for eligible routes.
Ensure spanning tree or loop protection blocks the redundant path.

Explanation

Correct Answer

Loop prevention protects bridged domains from uncontrolled circulation. The engineer should ensure spanning tree or loop protection blocks the redundant path.

Incorrect Answers

VSX coordinates two switches to provide multi-chassis LAG forwarding. It is not a direct remedy for the condition described.

Two supplies on one circuit do not protect against that circuit's failure. It is not a direct remedy for the condition described.

Equal-cost multipath distributes flows without a spanning-tree blocked uplink. It is not a direct remedy for the condition described.

Question 572

The engineer reports completing this change: Investigate airtime fairness and legacy data-rate impact. Which verification should be included in the handover?

Compare channel overlap and retry rates at several locations.
Compare airtime share and goodput by client PHY rate.
Disable the preferred uplink and check client traffic and AP management continuity.
Confirm the guest policy is enforced without examining private page bodies.

Explanation

Correct Answer

A slow client can occupy much airtime for comparatively few bytes. Compare airtime share and goodput by client PHY rate directly tests the desired behavior.

Incorrect Answers

CCI shares airtime while ACI disrupts reception through overlapping energy. That observation tests a different condition, not the required result.

AP resiliency requires compatible management and user VLAN reachability after switching links. That observation tests a different condition, not the required result.

Certificate visibility and full decryption have different privacy implications. That observation tests a different condition, not the required result.

Question 573

Following a campus change for this issue—two switches need encrypted traffic on a physically exposed Ethernet uplink—which result most directly verifies that the remedy works?

Verify RADIUS role assignment and allowed application traffic.
Verify guest cannot reach management ports while ops clients can.
Observe secure-channel negotiation and protected frame counters.
Try an allowed operation and a restricted admin operation.

Explanation

Correct Answer

MACsec protects selected Ethernet frames at Layer 2. Observe secure-channel negotiation and protected frame counters directly tests the desired behavior.

Incorrect Answers

Roles can express differentiated access independent of separate SSID proliferation. That observation tests a different condition, not the required result.

Controller/AP administration must be protected from public client VLANs. That observation tests a different condition, not the required result.

Individual accounts enable accountability and least-privilege authorization. That observation tests a different condition, not the required result.

Question 574

For an HPE Aruba Networking campus deployment, an administrator needs differentiated command privileges on AOS-CX switches. Which action best addresses it?

Set a narrowly scoped critical/backup authorization role.
Install the required trust anchor or replace the untrusted certificate.
Fix the returned VLAN/role attributes and effective enforcement settings.
Configure supported TACACS+/RBAC command authorization.

Explanation

Correct Answer

Authentication identifies administrators; authorization controls permitted commands. The engineer should configure supported TACACS+/RBAC command authorization.

Incorrect Answers

A RADIUS outage should not imply blanket production access. It is not a direct remedy for the condition described.

EAP-TLS succeeds only with a valid trusted certificate chain. It is not a direct remedy for the condition described.

Authentication success and assigned authorization policy are separate decisions. It is not a direct remedy for the condition described.

Question 575

Two AOS-CX core peers require active downstream multichassis link aggregation. Which change most directly meets this campus requirement?

Build a supported VSX pair with matching VSX LAG configuration.
Configure the downstream bundle and upstream VSX LAG consistently.
Restore the peer keepalive path without assuming the ISL itself failed.
Keep healthy LAG members forwarding while removing the failed link.

Explanation

Correct Answer

VSX coordinates two switches to provide multi-chassis LAG forwarding. The engineer should build a supported VSX pair with matching VSX LAG configuration.

Incorrect Answers

Multichassis aggregation depends on coordinated LAG identity at the peer pair. It is not a direct remedy for the condition described.

VSX keepalive is a separate liveness mechanism from the ISL. It is not a direct remedy for the condition described.

LACP aggregation can survive individual member loss. It is not a direct remedy for the condition described.

Question 576

An engineer is planning corrective work because an attacker attaches a small switch and tries to become STP root. Which step should be prioritized?

Apply STP root or BPDU protection on appropriate edge ports.
Require consistent trunk/access settings and disable unnecessary trunks.
Use SNMPv3 authentication and privacy where supported.
Apply a role-based ACL or firewall policy denying restricted destinations.

Explanation

Correct Answer

STP protections constrain unauthorized topology control. The engineer should apply STP root or BPDU protection on appropriate edge ports.

Incorrect Answers

Incorrect allowed/native VLAN settings weaken L2 segmentation. It is not a direct remedy for the condition described.

SNMPv3 can authenticate and encrypt management telemetry. It is not a direct remedy for the condition described.

VLAN placement by itself may not enforce the intended least privilege. It is not a direct remedy for the condition described.

Question 577

After completing the planned work for this situation—a switch sends EAPOL but no RADIUS request leaves the management VRF—how should success be checked?

Test both capable and non-802.1X endpoints and inspect selected method.
Test phone and laptop simultaneously with separate authorizations.
Inspect server logs for authenticator failures and retest.
Capture EAPOL at the port and UDP RADIUS toward the server.

Explanation

Correct Answer

EAPOL client traffic still needs the authenticator to reach RADIUS. Capture EAPOL at the port and UDP RADIUS toward the server directly tests the desired behavior.

Incorrect Answers

Auth-method priority avoids bypassing strong identities prematurely. That observation tests a different condition, not the required result.

Phone and data station may require separate access identities and roles. 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.

Question 578

An engineer is planning corrective work because an admin mistakenly trusts all ingress DSCP markings from guest clients. Which step should be prioritized?

Preserve security audit logs while tuning alerting separately.
Replace plaintext admin access with SSH/HTTPS and scoped management ACLs.
Use DHCP snooping with correctly designated trust boundaries.
Reclassify or remark untrusted ingress traffic at the boundary.

Explanation

Correct Answer

Untrusted clients can self-mark traffic to obtain an undeserved priority. The engineer should reclassify or remark untrusted ingress traffic at the boundary.

Incorrect Answers

Audit evidence is necessary even when alert thresholds create noise. It is not a direct remedy for the condition described.

Secure administration requires both encryption and source restriction. It is not a direct remedy for the condition described.

DHCP snooping can block server responses on untrusted access links. It is not a direct remedy for the condition described.

Question 579

A network team reports the following condition: A switch stack splits during a single member reboot. Select the most appropriate response.

Check stack link topology and supported redundant member cabling.
Configure at least one endpoint to initiate LACP actively.
Validate the AP wired-port bridge mode, allowed VLAN and required access policy.
Budget total power draw before enabling all powered ports.

Explanation

Correct Answer

A resilient stack topology avoids relying on one physical intermember path. The engineer should check stack link topology and supported redundant member cabling.

Incorrect Answers

Passive LACP endpoints do not initiate the exchange needed to negotiate a bundle. It is not a direct remedy for the condition described.

The AP uplink does not automatically grant all attached wired port traffic. It is not a direct remedy for the condition described.

A shared PoE power budget can limit the number of fully powered endpoints. It is not a direct remedy for the condition described.

Question 580

A network team reports the following condition: Two VSX peers report keepalive loss while their ISL remains up. Select the most appropriate response.

Design a supported ring or alternate stack-link topology.
Restore the peer keepalive path without assuming the ISL itself failed.
Ensure spanning tree or loop protection blocks the redundant path.
Apply matching active-gateway settings on both supported SVIs.

Explanation

Correct Answer

VSX keepalive is a separate liveness mechanism from the ISL. The engineer should restore the peer keepalive path without assuming the ISL itself failed.

Incorrect Answers

Redundant stacking paths can preserve member connectivity after one link fails. It is not a direct remedy for the condition described.

Loop prevention protects bridged domains from uncontrolled circulation. It is not a direct remedy for the condition described.

Active-gateway settings must be consistent across VSX peers. It is not a direct remedy for the condition described.
