HP HPE7-A01 Practice Test 71

Question 700

A warehouse deployment needs accurate client location, but APs were installed with no stable coordinate or floor map assignment. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Test 802.11r interoperability rather than enabling it blindly on every SSID.
  2. Audit AP coordinates after moves, renovations and device replacements.
  3. Track every SSID-to-profile association in change management.
  4. Check country code and antenna model before approving radio templates.

Explanation

Correct Answer

B:

This is a continuing control for the failure mode in which client localization depends on accurate reference positions and RF geometry. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a retail site uses multiple AP models but a uniform antenna-gain configuration that overstretches permitted EIRP in some areas. It would leave the present failure mode insufficiently addressed.

Question 701

An engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Test voice service with actual supported client devices.
  2. Use staged certificate rotation and managed supplicant trust updates.
  3. Maintain exception expiry dates for devices lacking required WPA capabilities.
  4. Run periodic spectrum and RF surveys after floor layout changes.

Explanation

Correct Answer

C:

This is a continuing control for the failure mode in which legacy-client limitations conflict with the security policy for management-frame protection. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a VoIP design attempts to solve poor call quality solely by raising AP power while clients still transmit at weak power levels. It would leave the present failure mode insufficiently addressed.

B:

That control is useful for a different failure, such as when an employee WLAN uses EAP-TLS and clients fail immediately after a RADIUS server certificate renewal. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a hospital's staff WLAN has strong signal near APs but frequent retries in a wing where two adjacent APs use the same busy 2.4 GHz channel. It would leave the present failure mode insufficiently addressed.

Question 702

A large office wants better distribution of capable clients between 2.4 and 5 GHz but all steer to 2.4 after a new RF policy. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Keep neighbor reporting consistent across the mobility domain.
  2. Test role assignment for negative identities during identity-provider changes.
  3. Monitor radar events and use regulatory-safe channel planning.
  4. Validate band steering after large RF-policy changes.

Explanation

Correct Answer

D:

This is a continuing control for the failure mode in which the new selection policy fails to guide dual-band clients to the desired 5 GHz capacity. It complements the immediate fix instead of relying on a one-off correction.

A:

That control is useful for a different failure, such as when a location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. It would leave the present failure mode insufficiently addressed.

B:

That control is useful for a different failure, such as when a wireless role design assumes connecting to the corporate SSID always grants internal network privileges even when a guest certificate authenticates. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when an AP shows DFS radar events and channels change during business hours, interrupting some clients. It would leave the present failure mode insufficiently addressed.

Question 703

A campus core has a default route toward a failed WAN link, while the healthy standby WAN is not preferred. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Standardize routing timers within approved network segments.
  2. Rehearse route failover with gateway and remote reachability checks.
  3. Allocate router IDs from a controlled unique registry.
  4. Keep route metric decisions in a documented traffic engineering plan.

Explanation

Correct Answer

B:

This is a continuing control for the failure mode in which the active default route remains installed despite a nonforwarding primary path. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a data center's OSPF router and campus peer have matching area IDs but fail adjacency because their hello/dead timers differ. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when an OSPF domain has duplicate router IDs after a lab switch image is cloned into production. It would leave the present failure mode insufficiently addressed.

That control is useful for a different failure, such as when a branch has two equally routed core uplinks, but one should be reserved as a backup for high-priority traffic. It would leave the present failure mode insufficiently addressed.

Question 704

A distribution switch cannot reach an application subnet because its static route references an incorrect next-hop IP. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Review static next-hop reachability after topology changes.
  2. Validate area topology before routing changes or new site turnup.
  3. Document per-VRF ownership of routes and permitted route leaking.
  4. Include negative traffic tests in every PBR deployment.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which the forwarding table sends application packets toward a nonexistent or wrong neighbor. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when an OSPF multi-area design attaches a remote area directly to another remote area without an approved backbone connection or virtual-link design. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a campus routes guest and employee traffic in separate VRFs but a technician adds a guest static route only to the employee VRF. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a campus uses policy-based routing to force a selected application through a service appliance, but a catch-all policy inadvertently redirects user DNS traffic too. It would leave the present failure mode insufficiently addressed.

Question 705

An OSPF adjacency remains in ExStart after a new routed uplink is installed with conflicting MTU settings. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Include MTU symmetry checks in routed-link provisioning.
  2. Require provider-supplied ASN verification before peer activation.
  3. Use a standard transit-address pool with mask validation.
  4. Monitor both peer-liveness signals and application reachability during failover tests.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which OSPF database exchange can fail when peers disagree on interface MTU. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when a campus BGP peering to an ISP remains Idle because the local neighbor remote-AS setting is incorrect. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a team adds a new L3 transit VLAN but configures the wrong IP mask on one side of the point-to-point link. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a core's next-hop route remains installed during a routed link fault because physical interface status stays up across an intermediate carrier. It would leave the present failure mode insufficiently addressed.

Question 706

Two Aruba CX routers run OSPF on a point-to-point uplink but show no neighbor because one interface is passive. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Include MTU symmetry checks in routed-link provisioning.
  2. Apply central IPAM checks before approving new subnets.
  3. Record passive and active OSPF interfaces in the routing design.
  4. Log prefix-filter changes and validate intended route inventories.

Explanation

Correct Answer

C:

This is a continuing control for the failure mode in which a passive OSPF interface advertises its network but does not send hello packets to form a neighbor. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when an OSPF adjacency remains in ExStart after a new routed uplink is installed with conflicting MTU settings. It would leave the present failure mode insufficiently addressed.

B:

Question 709

A campus routes guest and employee traffic in separate VRFs but a technician adds a guest static route only to the employee VRF. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Document per-VRF ownership of routes and permitted route leaking.
  2. Validate route specificity before implementing summaries or filters.
  3. Require both route and policy validation for new application flows.
  4. Log prefix-filter changes and validate intended route inventories.

Explanation
