HP HPE7-A01 Practice Test 119

Question 1180

A campus VLAN can reach its gateway but cannot access an internet SaaS site although neighboring VLANs can. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Follow the affected VLAN's gateway, NAT or perimeter policy and DNS path to the external destination.
  2. Check link state, authentication and assigned VLAN at the access edge before escalating to the core.
  3. Keep per-VLAN external access regression tests.
  4. Require controlled redistribution and prefix-policy reviews.

Explanation

Correct Answers

A:

This is the corrective intervention because local gateway success does not verify downstream routed, policy or name-resolution service. 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 wired client reports no network access, and a technician wants to replace the core router before inspecting the local port. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when two core switches disagree on an OSPF route after a configuration change, and one advertises a stale static prefix. It does not specifically prevent this problem.

Question 1181

A network administrator assumes a wireless slowdown is an ISP fault, but wired clients on the same WAN are fast. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Trace DHCP discover/offer/relay behavior and the assigned scope options.
  2. Use layer-by-layer triage starting at the failing endpoint.
  3. Measure RF airtime and wireless retransmissions before escalating the wired carrier.
  4. Compare wired and wireless baseline tests during performance incidents.

Explanation

Correct Answers

C:

This is the corrective intervention because the comparative evidence localizes the impairment to the wireless segment. 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: several users lose connectivity after a DHCP renewal while clients with static addresses continue working. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when a wired client reports no network access, and a technician wants to replace the core router before inspecting the local port. It does not specifically prevent this problem.

Question 1182

Two core switches disagree on an OSPF route after a configuration change, and one advertises a stale static prefix. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Investigate the management interface, VRF, DNS and cloud session separately from user forwarding.
  2. Inspect route sources, redistribution and current LSA state before resetting adjacencies.
  3. Require controlled redistribution and prefix-policy reviews.
  4. Include roaming walk tests in voice WLAN changes.

Explanation

Correct Answers

B:

This is the corrective intervention because an incorrect redistributed source can create inconsistent advertised reachability. 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 switch appears unreachable from Central yet local console shows healthy data-plane operation. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when voice handsets lose calls only after crossing between two APs, while stationary calls remain stable. It does not specifically prevent this problem.

Question 1183

A single client cannot reach a printer even though other clients in the same VLAN succeed. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Investigate the physical cable/optic path and fix the corruption before changing IP routes.
  2. Include EAP failure-stage codes in WLAN support workflows.
  3. Compare the failing client's address, authentication role and host firewall with a working peer.
  4. Use peer comparison when only one user is affected.

Explanation

Correct Answers

C:

This is the corrective intervention because the difference is likely endpoint-specific rather than a complete subnet outage. 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 user has a valid IP address but intermittent access to a local service, and switch counters show CRC errors. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when an AP reports excellent RF signal but EAP-TLS clients fail to join after a certificate update. It does not specifically prevent this problem.

Question 1184

Voice handsets lose calls only after crossing between two APs, while stationary calls remain stable. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Investigate the physical cable/optic path and fix the corruption before changing IP routes.
  2. Capture roaming and authentication handoff timing along the mobility path.
  3. Include roaming walk tests in voice WLAN changes.
  4. Use peer comparison when only one user is affected.

Explanation

Correct Answers

B:

This is the corrective intervention because the time-localized outage points to roaming continuity rather than all-call network capacity. 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 user has a valid IP address but intermittent access to a local service, and switch counters show CRC errors. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a single client cannot reach a printer even though other clients in the same VLAN succeed. It does not specifically prevent this problem.

Question 1185

A switch appears unreachable from Central yet local console shows healthy data-plane operation. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Restore a known approved configuration and institute version-controlled change review with acceptance checks.
  2. Investigate the management interface, VRF, DNS and cloud session separately from user forwarding.
  3. Include error-rate checks in LAN incident intake.
  4. Monitor out-of-band management status distinct from forwarding health.

Explanation

Correct Answers

B:

This is the corrective intervention because management connectivity loss does not necessarily imply switching outage. 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 campus deployment has repeated outages after hurried template changes, and the NOC has no versioned baseline for comparison. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a user has a valid IP address but intermittent access to a local service, and switch counters show CRC errors. It does not specifically prevent this problem.

Question 1186

A campus deployment has repeated outages after hurried template changes, and the NOC has no versioned baseline for comparison. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Follow the affected VLAN's gateway, NAT or perimeter policy and DNS path to the external destination.
  2. Restore a known approved configuration and institute version-controlled change review with acceptance checks.
  3. Monitor DHCP server health and relay error counters.
  4. Maintain versioned configuration snapshots, owner approval and rollback procedures.

Explanation

Correct Answers

B:

This is the corrective intervention because untracked configuration drift prevents reliable comparison and controlled rollback. 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 campus VLAN can reach its gateway but cannot access an internet SaaS site although neighboring VLANs can. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when several users lose connectivity after a DHCP renewal while clients with static addresses continue working. It does not specifically prevent this problem.

Question 1187

A voice deployment marks DSCP EF at its phones but the access switch does not trust or preserve the marking on ingress. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Use a documented combination of classification, scheduler weights and policing where required to protect other service classes.
  2. Apply the approved classification and trust boundary at the access edge for authorized voice devices.
  3. Audit QoS trust only on verified voice-access ports.
  4. Enforce QoS trust boundaries and classification tests on edge ports.

Explanation

Correct Answers

B:

This is the corrective intervention because priority markings are lost before traffic enters the campus QoS scheduling domain. 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 campus link carries video and backups, and strict high-priority queuing lets video consume bandwidth without a configured limit. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a switch receives ingress traffic marked with elevated priority from untrusted student PCs, starving approved voice traffic. It does not specifically prevent this problem.

Question 1188

A campus uplink gives backup traffic equal scheduling precedence to interactive voice and latency rises during backups. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Adjust minimum-rate policy based on actual edge-client capabilities and validated coverage.
  2. Assign traffic classes and appropriate queue scheduling so delay-sensitive voice receives protected service.
  3. Test QoS under congestion rather than idle conditions alone.
  4. Test slow legacy devices before changing radio minimum rates.

Explanation

Correct Answers

B:

This is the corrective intervention because without distinct QoS classes, bulk traffic can queue ahead of latency-sensitive packets. 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 WLAN operator sees clients reconnect every few minutes after aggressive radio minimum-rate changes, despite good aggregate throughput. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a wireless network has high airtime consumption from low legacy data rates despite moderate user counts. It does not specifically prevent this problem.

Question 1189

A video conferencing application uses DSCP AF41, but a policy rewrites all traffic to best effort at the distribution layer. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Preserve or correctly remark authorized real-time media classifications through the campus path.
  2. Apply the approved classification and trust boundary at the access edge for authorized voice devices.
  3. Report p95/p99 latency alongside mean in service-level monitoring.
  4. Review every QoS remarking boundary after routing or security upgrades.

Explanation

Correct Answers

A:

This is the corrective intervention because a broad remarking rule removes the priority distinction required by the intended service policy. 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 voice deployment marks DSCP EF at its phones but the access switch does not trust or preserve the marking on ingress. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when an application experiences 20 ms average latency but bursts to 250 ms during each storage transfer, causing user complaints. It does not specifically prevent this problem.

Question 1190

A wireless voice call has low RSSI but the WLAN team tries to repair it solely with DSCP priority rules. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Assign traffic classes and appropriate queue scheduling so delay-sensitive voice receives protected service.
  2. Correct the RF coverage and SNR deficit before expecting QoS to repair missing radio frames.
  3. Test QoS under congestion rather than idle conditions alone.
  4. Set RF minimum performance criteria in voice deployment acceptance.

Explanation

Correct Answers

B:

This is the corrective intervention because traffic priority cannot compensate for unusable wireless link quality. 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 campus uplink gives backup traffic equal scheduling precedence to interactive voice and latency rises during backups. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a campus uplink gives backup traffic equal scheduling precedence to interactive voice and latency rises during backups. It does not specifically prevent this problem.
