HP HPE7-A01 Practice Test 118

Question 1170

A switch team takes firmware backups but no configuration snapshot before a planned major change. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Capture and verify a restorable device configuration with a tested rollback path.
  2. Require configuration backup integrity checks before risky maintenance.
  3. Investigate the end-to-end user experience path including DNS, authentication and application response.
  4. Enforce API token ownership and change-ticket correlation.

Explanation

Correct Answers

A:

This is the corrective intervention because a software image alone does not reconstruct the previous running configuration. 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: UXI sensors show failed cloud-application transactions but the WLAN dashboard reports healthy client associations. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when an external automation script changes CX VLAN configuration but the operations team cannot trace when it happened. It does not specifically prevent this problem.

Question 1171

Central shows a device with the wrong site tag, causing its client statistics to appear under another location. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Correct the device inventory or site assignment without changing unrelated network behavior.
  2. Use authenticated API calls with individual service identities and change/audit logging.
  3. Enforce API token ownership and change-ticket correlation.
  4. Audit site and group assignments after device swaps.

Explanation

Correct Answers

A:

This is the corrective intervention because incorrect inventory metadata misgroups telemetry even when forwarding is healthy. 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: an external automation script changes CX VLAN configuration but the operations team cannot trace when it happened. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when an external automation script changes CX VLAN configuration but the operations team cannot trace when it happened. It does not specifically prevent this problem.

Question 1172

A campus operator enables verbose syslog locally but remote log storage shows no new events. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Configure a reachable remote syslog destination and supported severity/facility forwarding settings.
  2. Test log forwarding and retention after configuration changes.
  3. Set proper poller timeout and explicit unknown/down status handling rather than treating silence as health.
  4. Enforce API token ownership and change-ticket correlation.

Explanation

Correct Answers

A:

This is the corrective intervention because local log generation does not ensure delivery to the remote collector. 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 monitoring dashboard hides real device outages because its poller assumes success on missing SNMP responses. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when an external automation script changes CX VLAN configuration but the operations team cannot trace when it happened. It does not specifically prevent this problem.

Question 1173

A monitoring API integration stops receiving data after a credential rotation despite healthy switch and WAN links. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Configure a reachable remote syslog destination and supported severity/facility forwarding settings.
  2. Refresh the automation's authorized token or OAuth credentials and verify scope and expiry.
  3. Retain synthetic application tests for critical user journeys.
  4. Use controlled credential rotation and pre-expiration alerts.

Explanation

Correct Answers

B:

This is the corrective intervention because application API authentication failed; physical data forwarding still works. 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 operator enables verbose syslog locally but remote log storage shows no new events. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when UXI sensors show failed cloud-application transactions but the WLAN dashboard reports healthy client associations. It does not specifically prevent this problem.

Question 1174

An engineer sees high CPU on an access switch but proposes rebooting it immediately during the school day. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Correlate process or control-plane metrics with traffic and event logs before choosing a maintenance action.
  2. Set proper poller timeout and explicit unknown/down status handling rather than treating silence as health.
  3. Set CPU baselines and alert thresholds with documented escalation.
  4. Test loss-of-telemetry behavior in NOC alert reviews.

Explanation

Correct Answers

A:

This is the corrective intervention because high CPU alone does not identify its source or justify interrupting healthy traffic. 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 monitoring dashboard hides real device outages because its poller assumes success on missing SNMP responses. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a monitoring dashboard hides real device outages because its poller assumes success on missing SNMP responses. It does not specifically prevent this problem.

Question 1175

A wired client reports no network access, and a technician wants to replace the core router before inspecting the local port. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Check link state, authentication and assigned VLAN at the access edge before escalating to the core.
  2. Use layer-by-layer triage starting at the failing endpoint.
  3. Compare the failing client's address, authentication role and host firewall with a working peer.
  4. Maintain versioned configuration snapshots, owner approval and rollback procedures.

Explanation

Correct Answers

A:

This is the corrective intervention because the failure may originate at the access interface, where core replacement would not correct it. 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 single client cannot reach a printer even though other clients in the same VLAN succeed. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a campus deployment has repeated outages after hurried template changes, and the NOC has no versioned baseline for comparison. It does not specifically prevent this problem.

Question 1176

Only one floor's wireless clients cannot reach DNS while other floors on the same SSID work. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Compare the affected AP's client VLAN transport and DHCP-provided DNS against the healthy floor.
  2. Check link state, authentication and assigned VLAN at the access edge before escalating to the core.
  3. Use layer-by-layer triage starting at the failing endpoint.
  4. Maintain healthy-floor baselines for rapid comparison.

Explanation

Correct Answers

A:

This is the corrective intervention because the localized failure suggests a site-specific client subnet or uplink difference. 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 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.

C:

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 1177

A user has a valid IP address but intermittent access to a local service, and switch counters show CRC errors. 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. Investigate the physical cable/optic path and fix the corruption before changing IP routes.
  3. Include error-rate checks in LAN incident intake.
  4. Compare wired and wireless baseline tests during performance incidents.

Explanation

Correct Answers

B:

This is the corrective intervention because frame corruption can create sporadic loss despite correct Layer 3 settings. 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 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.

D:

That safeguard would suit a different situation, such as when a network administrator assumes a wireless slowdown is an ISP fault, but wired clients on the same WAN are fast. It does not specifically prevent this problem.

Question 1178

Several users lose connectivity after a DHCP renewal while clients with static addresses continue working. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Compare the affected AP's client VLAN transport and DHCP-provided DNS against the healthy floor.
  2. Keep per-VLAN external access regression tests.
  3. Trace DHCP discover/offer/relay behavior and the assigned scope options.
  4. Monitor DHCP server health and relay error counters.

Explanation

Correct Answers

C:

This is the corrective intervention because the symptom localizes to address assignment or renewal rather than general switching failure. 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: only one floor's wireless clients cannot reach DNS while other floors on the same SSID work. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when a campus VLAN can reach its gateway but cannot access an internet SaaS site although neighboring VLANs can. It does not specifically prevent this problem.

Question 1179

An AP reports excellent RF signal but EAP-TLS clients fail to join after a certificate update. 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. Check supplicant and RADIUS certificate negotiation rather than altering the radio channel plan.
  3. Include EAP failure-stage codes in WLAN support workflows.
  4. Monitor DHCP server health and relay error counters.

Explanation

Correct Answers

B:

This is the corrective intervention because authentication failure occurs after RF discovery; radio strength is not the limiting factor. 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 several users lose connectivity after a DHCP renewal while clients with static addresses continue working. It does not specifically prevent this problem.

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.
