HP HPE7-A01 Practice Test 28
Question 270
A distribution switch has VLAN membership configured but no working gateway SVI for inter-VLAN routing after a site migration. After the root cause is confirmed, which narrowly scoped configuration action should be selected?
- Permit the approved tagged VLAN IDs on both ends and set compatible native or untagged VLAN handling for the affected campus deployment.
- Match the native VLAN to the approved design or explicitly tag the required traffic on both sides.
- Set up compatible LACP participation on both ends and bundle only links with matching attributes.
- Establish or restore the authorized routed VLAN interface and its routing or ACL context, keeping access ports Layer 2.
Explanation
Correct Answer
D:Establish or restore the authorized routed VLAN interface and its routing or ACL context, keeping access ports Layer 2. A Layer 2 VLAN groups frames, whereas an SVI provides an IP routing interface; one does not automatically create the other. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described svi versus layer 2 access interface situation.
Incorrect Answers
A:Permit the approved tagged VLAN IDs on both ends and set compatible native or untagged VLAN handling for the affected campus deployment. This instead concerns vlan tagging on an 802.1q trunk. An IEEE 802.1Q trunk carries multiple VLANs by tags; permitted VLAN membership and native-tag treatment must agree across the link. It would not implement the specifically required change. The immediate problem concerns svi versus layer 2 access interface.
B:Match the native VLAN to the approved design or explicitly tag the required traffic on both sides. This instead concerns native vlan mismatch. A native VLAN mismatch can silently classify untagged frames into different broadcast domains, even while tagged VLANs operate normally. It would not implement the specifically required change. The immediate problem concerns svi versus layer 2 access interface.
C:Set up compatible LACP participation on both ends and bundle only links with matching attributes. This instead concerns lacp mode compatibility. LACP negotiation depends on both peers participating in a compatible aggregation; unrelated physical ports cannot safely imitate a bundled link. It would not implement the specifically required change. The immediate problem concerns svi versus layer 2 access interface.
Question 271
A distribution switch has VLAN membership configured but no working gateway SVI for inter-VLAN routing after a site migration. A deployment job reports success. Which observed result would actually validate the affected service?
- Collect tagged test frames and verify each client VLAN reaches only its intended gateway.
- Confirm untagged frames map to the intended VLAN and management traffic remains isolated from client networks.
- Confirm same-VLAN switching and permitted cross-VLAN routing through the intended SVI without unexpected leakage.
- Confirm the negotiated aggregator and active collecting or distributing member set are stable under traffic.
Explanation
Correct Answer
C:Confirm same-VLAN switching and permitted cross-VLAN routing through the intended SVI without unexpected leakage. A Layer 2 VLAN groups frames, whereas an SVI provides an IP routing interface; one does not automatically create the other. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described svi versus layer 2 access interface situation.
Incorrect Answers
A:Collect tagged test frames and verify each client VLAN reaches only its intended gateway. This instead concerns vlan tagging on an 802.1q trunk. An IEEE 802.1Q trunk carries multiple VLANs by tags; permitted VLAN membership and native-tag treatment must agree across the link. It would not establish that this function actually works. The immediate problem concerns svi versus layer 2 access interface.
B:Confirm untagged frames map to the intended VLAN and management traffic remains isolated from client networks. This instead concerns native vlan mismatch. A native VLAN mismatch can silently classify untagged frames into different broadcast domains, even while tagged VLANs operate normally. It would not establish that this function actually works.

Question 272
A distribution switch has VLAN membership configured but no working gateway SVI for inter-VLAN routing after a site migration. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.
- Review trunk allowed VLANs, tag state and the connected device's matching VLAN expectations.
- Review VLAN membership, switched-port state, SVI IP address and whether Layer 3 forwarding is enabled on the intended device.
- Match the native VLAN to the approved design or explicitly tag the required traffic on both sides.
- Establish or restore the authorized routed VLAN interface and its routing or ACL context, keeping access ports Layer 2.
Explanation
Correct Answers
B:Review VLAN membership, switched-port state, SVI IP address and whether Layer 3 forwarding is enabled on the intended device. A Layer 2 VLAN groups frames, whereas an SVI provides an IP routing interface; one does not automatically create the other. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described svi versus layer 2 access interface situation.

Incorrect Answers
A:Review trunk allowed VLANs, tag state and the connected device's matching VLAN expectations. This instead concerns vlan tagging on an 802.1q trunk. An IEEE 802.1Q trunk carries multiple VLANs by tags; permitted VLAN membership and native-tag treatment must agree across the link. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns svi versus layer 2 access interface.
C:Match the native VLAN to the approved design or explicitly tag the required traffic on both sides. This instead concerns native vlan mismatch. A native VLAN mismatch can silently classify untagged frames into different broadcast domains, even while tagged VLANs operate normally.

Question 273
A school requests blanket Wi-Fi coverage after complaints, but performance collapses only during crowded assemblies. Which investigation would best isolate the immediate network dependency?
- Inspect channel assignments, measured interference and busy-time statistics across nearby 2.4 GHz access points.
- Compare measured RSSI and SNR with airtime utilization, client density and application throughput per AP.
- Inspect DFS events, local regulatory domain and recent channel changes for the affected AP radios.
- Inspect client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security.
Explanation
Correct Answer
B:Compare measured RSSI and SNR with airtime utilization, client density and application throughput per AP. Good signal strength does not guarantee capacity; simultaneous client airtime demand and channel reuse govern dense WLAN performance. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described rf site survey coverage versus capacity situation.
Incorrect Answers
A:Inspect channel assignments, measured interference and busy-time statistics across nearby 2.4 GHz access points. This instead concerns 2.4 ghz nonoverlapping channels. The 2.4 GHz band has limited nonoverlapping 20 MHz channels; indiscriminate channel placement wastes scarce airtime. It does not isolate the cause of the stated incident. The immediate problem concerns rf site survey coverage versus capacity.
C:Inspect DFS events, local regulatory domain and recent channel changes for the affected AP radios. This instead concerns 5 ghz dfs channel radar events. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. It does not isolate the cause of the stated incident. The immediate problem concerns rf site survey coverage versus capacity.
D:Inspect client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security. This instead concerns 6 ghz regulatory and client capabilities. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. It does not isolate the cause of the stated incident. The immediate problem concerns rf site survey coverage versus capacity.
Question 274
A school requests blanket Wi-Fi coverage after complaints, but performance collapses only during crowded assemblies. Which specific corrective design step best meets the stated campus requirement?
- Use a capacity-aware RF design with properly placed APs and channels instead of increasing transmit power uniformly.
- Use a supported narrow-channel 2.4 GHz reuse plan with nonoverlapping choices appropriate to regional regulations.
- Choose an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection.
- Keep compatible service on supported bands and enable 6 GHz only for capable clients with regulatory-compliant security.
Explanation
Correct Answer
A:Use a capacity-aware RF design with properly placed APs and channels instead of increasing transmit power uniformly. Good signal strength does not guarantee capacity; simultaneous client airtime demand and channel reuse govern dense WLAN performance. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described rf site survey coverage versus capacity situation.

Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. It would not implement the specifically required change. The immediate problem concerns rf site survey coverage versus capacity.
D:Keep compatible service on supported bands and enable 6 GHz only for capable clients with regulatory-compliant security. This instead concerns 6 ghz regulatory and client capabilities.

It would not implement the specifically required change. The immediate problem concerns rf site survey coverage versus capacity.
Question 275
A school requests blanket Wi-Fi coverage after complaints, but performance collapses only during crowded assemblies. Following a targeted change, which acceptance test would most directly demonstrate success?
- Confirm reduced adjacent-channel interference and improved retries under equivalent client demand.
- Verify the AP moves to a permitted channel on a DFS event and clients reconnect in acceptable time.
- Verify capable test clients discover and associate on 6 GHz while legacy devices still use an approved alternative band.
- Validate representative loaded client throughput and airtime alongside minimum required signal at seating locations.
Explanation
Correct Answer
D:Validate representative loaded client throughput and airtime alongside minimum required signal at seating locations. Good signal strength does not guarantee capacity; simultaneous client airtime demand and channel reuse govern dense WLAN performance. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described rf site survey coverage versus capacity situation.

Question 276
A school requests blanket Wi-Fi coverage after complaints, but performance collapses only during crowded assemblies. The change fails acceptance. What is the safest targeted restoration action?
- Restore stable channel assignments and avoid a broad channel-width increase while site-specific RF design is retuned.
- Revert to known permitted non-DFS channels for affected service areas if DFS moves break required client support.
- Restore the prior RF plan while selectively reducing congested cell size and retesting a busy-area sample.
- Restore the previous multi-band WLAN and remove unsupported 6 GHz-only assumptions until endpoint capabilities are validated.
Explanation
Correct Answer
C:Restore the prior RF plan while selectively reducing congested cell size and retesting a busy-area sample. Good signal strength does not guarantee capacity; simultaneous client airtime demand and channel reuse govern dense WLAN performance. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described rf site survey coverage versus capacity situation.
Incorrect Answers
A:Restore stable channel assignments and avoid a broad channel-width increase while site-specific RF design is retuned. This instead concerns 2.4 ghz nonoverlapping channels. The 2.4 GHz band has limited nonoverlapping 20 MHz channels; indiscriminate channel placement wastes scarce airtime. It would not safely roll back the relevant failed change. The immediate problem concerns rf site survey coverage versus capacity.
B:Revert to known permitted non-DFS channels for affected service areas if DFS moves break required client support. This instead concerns 5 ghz dfs channel radar events. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. It would not safely roll back the relevant failed change.

Question 277
A convention floor has strong reported RSSI yet slow client experience when hundreds of users share a few access points. Before implementing a remedy, what should the engineer check first?
