HP HPE7-A01 Practice Test 107

Question 1060

A distribution switch applies an ingress ACL to a routed SVI, but administrators expect it to block frames bridged only inside the same VLAN. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Correct the gateway SVI subnet mask to the approved addressing plan.
  2. Choose the supported policy enforcement point for Layer 2 traffic instead of relying on an SVI routed ACL alone.
  3. Map each policy requirement to the actual transit and enforcement layer.
  4. Version-control MST region mappings as a single campus standard.

Explanation

Correct Answers

B:

This is the corrective intervention because an L3 SVI ACL may not inspect traffic that never traverses that routed interface. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a new Layer 3 switch hosts the user VLAN gateway but the SVI mask excludes part of the expected address range. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a newly enabled MSTP configuration blocks the wrong uplink because two switches assign VLANs to inconsistent instances. It does not specifically prevent this problem.

Question 1061

A client subnet uses an on-box DHCP relay but its requests never reach the centralized server after a VRF split. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Implement supported user-role or microsegmentation policy based on the authenticated identity or client class.
  2. Keep user-facing ports untrusted and alert on rogue server attempts.
  3. Configure the relay destination and source within the correct VLAN and VRF reachability context.
  4. Test DHCP relay reachability after VRF migrations.

Explanation

Correct Answers

C:

This is the corrective intervention because the relay packet cannot reach the approved DHCP server from its chosen forwarding table. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a security requirement calls for isolating two guest groups inside one SSID, but both groups land in an unrestricted shared VLAN. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when a rogue small office router begins answering DHCP on an open desk port. It does not specifically prevent this problem.

Question 1062

A switch trunk's CRC error counters climb while application traffic degrades after a fiber transceiver change. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Replace or align the unsupported optic/cable and verify physical-layer compatibility.
  2. Restore the authorized member port and the VLAN's operational state.
  3. Review trunk allow lists during AP and SSID changes.
  4. Track approved optic types and cable reach by platform.

Explanation

Correct Answers

A:

This is the corrective intervention because CRC errors indicate physical frame corruption rather than a VLAN-routing configuration error. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

B:

This action fits a different incident: a CX switch has a healthy SVI but hosts cannot reach the directly connected gateway because the VLAN has no active member ports. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when an AP trunk has every VLAN enabled, allowing guest client traffic onto a restricted internal network. It does not specifically prevent this problem.

Question 1063

A LAG uses a hash selection that causes one large storage flow to occupy a single member while other links remain mostly idle. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Explain per-flow hashing behavior and distribute independent flows rather than assuming one flow is striped packet-by-packet.
  2. Document LAG per-flow load-distribution expectations in capacity forecasts.
  3. Implement supported user-role or microsegmentation policy based on the authenticated identity or client class.
  4. Keep physical port-to-VLAN mappings in endpoint provisioning records.

Explanation

Correct Answers

A:

This is the corrective intervention because conventional Ethernet LAG hashing normally keeps a single flow on one member to preserve ordering. Confirm its effect using the specified operational recovery check.

B:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

C:

This action fits a different incident: a security requirement calls for isolating two guest groups inside one SSID, but both groups land in an unrestricted shared VLAN. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a new finance printer is connected to an access port in VLAN 130, but the subnet gateway is an SVI in VLAN 120. It does not specifically prevent this problem.

Question 1064

A security requirement calls for isolating two guest groups inside one SSID, but both groups land in an unrestricted shared VLAN. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Move the port to the approved finance VLAN and ensure the correct SVI and DHCP scope are used.
  2. Implement supported user-role or microsegmentation policy based on the authenticated identity or client class.
  3. Keep physical port-to-VLAN mappings in endpoint provisioning records.
  4. Retest role-based separation when identity or WLAN mappings change.

Explanation

Correct Answers

B:

This is the corrective intervention because sharing an SSID or VLAN does not by itself enforce group-level east-west restrictions. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a new finance printer is connected to an access port in VLAN 130, but the subnet gateway is an SVI in VLAN 120. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a new finance printer is connected to an access port in VLAN 130, but the subnet gateway is an SVI in VLAN 120. It does not specifically prevent this problem.

Question 1065

A management interface is configured with an IPv6 address, but SNMPv3 traffic never leaves because its selected management VRF lacks an IPv6 default route. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Explain per-flow hashing behavior and distribute independent flows rather than assuming one flow is striped packet-by-packet.
  2. Install the authorized IPv6 route in the management VRF and verify protocol reachability.
  3. Include IPv6 management routes in dual-stack change templates.
  4. Reserve gateway IPs and validate redundancy design before provisioning.

Explanation

Correct Answers

B:

This is the corrective intervention because the management routing table has no IPv6 path to the collector. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a LAG uses a hash selection that causes one large storage flow to occupy a single member while other links remain mostly idle. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when an engineer configures a VLAN SVI for default gateway service but accidentally assigns the same IPv4 address to another independent router without VRRP or active-gateway design. It does not specifically prevent this problem.

Question 1066

An access switch shows a large unknown-unicast flood after several upstream MAC addresses aged out too quickly. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Correct the approved MAC aging policy and investigate missing refresh traffic before broad flooding exceptions.
  2. Restrict the trunk's allowed VLAN list to the management and WLAN client VLANs actually required.
  3. Monitor MAC table occupancy and churn for high-density VLANs.
  4. Retest role-based separation when identity or WLAN mappings change.

Explanation

Correct Answers

A:

This is the corrective intervention because aged-out destinations cause Layer 2 unknown-unicast flooding until relearned. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

B:

This action fits a different incident: an AP trunk has every VLAN enabled, allowing guest client traffic onto a restricted internal network. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a security requirement calls for isolating two guest groups inside one SSID, but both groups land in an unrestricted shared VLAN. It does not specifically prevent this problem.

Question 1067

A VSX downstream switch has an active multi-chassis LAG, but the primary and secondary peers disagree on the permitted client VLANs. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Correct the gateway SVI subnet mask to the approved addressing plan.
  2. Document MTU expectations across the entire service path.
  3. Synchronize or align the VSX multi-chassis LAG VLAN configuration on both peers.
  4. Require VSX LAG configuration consistency checks before change approval.

Explanation

Correct Answers

C:

This is the corrective intervention because inconsistent peer-side LAG settings can create asymmetric forwarding after failover. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a new Layer 3 switch hosts the user VLAN gateway but the SVI mask excludes part of the expected address range. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when a service requires large Ethernet payloads, but a path across several CX switches drops only oversized frames. It does not specifically prevent this problem.

Question 1068

An engineer configures a VLAN SVI for default gateway service but accidentally assigns the same IPv4 address to another independent router without VRRP or active-gateway design. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Remove the conflicting address and deploy a supported unique or shared virtual gateway design.
  2. Explain per-flow hashing behavior and distribute independent flows rather than assuming one flow is striped packet-by-packet.
  3. Reserve gateway IPs and validate redundancy design before provisioning.
  4. Validate virtualization host VLAN mappings against switchport mode.

Explanation

Correct Answers

A:

This is the corrective intervention because duplicated unmanaged gateway IP ownership causes ARP instability and conflicting replies. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

B:

This action fits a different incident: a LAG uses a hash selection that causes one large storage flow to occupy a single member while other links remain mostly idle. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a switch port connected to a hypervisor must carry three isolated tenant VLANs, but it is left in access mode. It does not specifically prevent this problem.

Question 1069

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. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Base enforcement on validated user or device attributes and assigned access role, not the SSID name alone.
  2. Track every SSID-to-profile association in change management.
  3. Replan the 2.4 GHz channel assignments using nonoverlapping channels and measured interference.
  4. Run periodic spectrum and RF surveys after floor layout changes.

Explanation

Correct Answers

C:

This is the corrective intervention because co-channel contention in a shared 2.4 GHz channel increases airtime competition even with strong signal. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a wireless role design assumes connecting to the corporate SSID always grants internal network privileges even when a guest certificate authenticates. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, 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 does not specifically prevent this problem.

Question 1070

An office installs a new 6 GHz-capable AP, but an older 802.11ac laptop cannot detect the dedicated 6 GHz-only SSID. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Replan the 2.4 GHz channel assignments using nonoverlapping channels and measured interference.
  2. Provide an appropriate supported 5 GHz service for legacy clients instead of assuming 6 GHz backward compatibility.
  3. Maintain a device band-capability inventory when expanding Wi-Fi 6E coverage.
  4. Require predictive and post-deployment validation for material building changes.

Explanation

Correct Answers

B:

This is the corrective intervention because a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: 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 is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a wireless floor gets poor coverage behind dense concrete despite high AP transmit power in the corridor. It does not specifically prevent this problem.
