Question 1020

At Learning Commons, a handheld shows strong signal but high retry rate beside machinery at lunch hour. Which test best differentiates real success from a merely healthy status light?

  1. Verify the user reaches only the assigned subnet and policy resources.
  2. Retune a controlled radio and verify improved SNR plus voice packet success.
  3. Replace the suspect physical component and verify error rates stabilize under traffic.
  4. Prove permitted bidirectional application traffic reaches the endpoint.

Explanation

Correct Answer

B:

For Learning Commons, the decisive mechanism is Low SNR wireless retries. Signal strength without a noise context cannot establish usable WLAN quality. Retune a controlled radio and verify improved SNR plus voice packet success supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

C:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

D:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

Question 1021

At Medical Annex, a visitor SSID is reachable but users can access internal management servers. Which controlled acceptance test demonstrates the required behavior?

  1. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  2. Correlate a test session and termination with the intended accounting records.
  3. Demonstrate Internet access and blocked access to internal test endpoints.
  4. Test allowed application connectivity and rejected unauthorized east-west traffic.

Explanation

Correct Answer

C:

For Medical Annex, the decisive mechanism is Guest segmentation. Guest network segmentation depends on enforced policy, not only SSID naming. Demonstrate Internet access and blocked access to internal test endpoints supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to EAP-TLS client certificate validation, where eAP-TLS authenticates possession of the client certificate private key and validates trust In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

B:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

D:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

Question 1022

At Innovation Studio, a campus migration introduces gateway versions with incompatible feature behavior. Which controlled configuration is most likely to restore the required service?

  1. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  2. Apply an RF plan with reasonable channel reuse and channel width for expected density.
  3. Apply supported clustered gateway configuration with capacity and software-version compatibility.
  4. Perform an active site survey covering attenuation interference and realistic client density.

Explanation

Correct Answer

C:

For Innovation Studio, the decisive mechanism is Gateway cluster resiliency. Tunneled service resilience requires usable gateway capacity and working AP tunnels. Use supported clustered gateway configuration with capacity and software-version compatibility establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

D:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

Question 1023

At Convention Center, a staff pilot changes a personal SSID to WPA3-SAE and older tablets fail to connect. What should be examined to confirm the actual failure mechanism?

  1. Inspect surveyed RSSI SNR channel use and roaming measurements at user positions.
  2. Compare RSSI noise floor SNR and retransmissions per affected client.
  3. Inspect co-channel AP visibility airtime utilization and contention counters.
  4. Inspect AKM suite and SAE handshake failure codes on incompatible stations.

Explanation

Correct Answer

D:

For Convention Center, the decisive mechanism is WPA3 SAE personal WLAN. SAE changes personal WLAN authentication compared with WPA2-PSK. Inspect AKM suite and SAE handshake failure codes on incompatible stations is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

B:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

Question 1024

At Engineering Tower, a 1-Gb campus uplink drops to half duplex after a transceiver change while both devices report carrier. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Retain RADIUS failover and a defined restricted fallback for the expected device class.
  2. Align compatible speed and duplex negotiation at both Ethernet endpoints before testing traffic.
  3. Preserve approved transceiver and link-setting baselines for any future port migration.
  4. Compare supported 802.11 association capabilities and RSN requirements before troubleshooting IP services.

Explanation

Correct Answers

B:

This is the implementation element for the Engineering Tower case: 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation. The specific action Align compatible speed and duplex negotiation at both Ethernet endpoints before testing traffic addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Engineering Tower. Preserve approved transceiver and link-setting baselines for any future port migration prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be an ongoing precaution for 802.1X EAPOL versus IP service: 802.1X is port-based access control; IP configuration occurs after network admission. It does not resolve the Ethernet negotiation and duplex requirement in Engineering Tower and is not one of the two controls requested. The direct mechanism here is 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation

D:

This may be a configuration step for 802.11 association sequence: 802.11 discovery and association occur before user traffic can be successfully forwarded. It does not resolve the Ethernet negotiation and duplex requirement in Engineering Tower and is not one of the two controls requested. The direct mechanism here is 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation

Question 1025

At Technology Center, multicast traffic floods low-rate wireless airtime during a live classroom presentation. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  2. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.
  3. Use supported egress queue scheduling with bounded high-priority service treatment.
  4. Evaluate supported multicast conversion and membership control for the audience size.

Explanation

Correct Answer

D:

For Technology Center, the decisive mechanism is Multicast-to-unicast tradeoff. Multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work. Evaluate supported multicast conversion and membership control for the audience size establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work

B:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work

C:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work

Question 1026

  1. Use supported clustered gateway configuration with capacity and software-version compatibility.
  2. Perform an active site survey covering attenuation interference and realistic client density.
  3. Configure guest authentication flow and role transitions with appropriate enforcement.
  4. Adjust mounting antenna orientation and power using active RF measurements.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is RF predictive versus active survey. Predictive RF planning does not replace measured real-world attenuation and utilization. Perform an active site survey covering attenuation interference and realistic client density establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

C:

The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

Question 1027

At East Student Center, a CX switch interface flaps intermittently and the NOC wants local time-series evidence. What targeted evidence should the network engineer collect first?

  1. Examine NAE agent status monitored resource expression and recent event history.
  2. Examine requested API version selector depth and response attribute groups.
  3. Examine each synthetic step and route from the sensor's actual network.
  4. Examine CRC input drops queue discards and rate correlation on the affected port.

Explanation

Correct Answer

A:

For East Student Center, the decisive mechanism is NAE monitor rule. NAE agents monitor local switch state and can correlate rule conditions over time. Inspect NAE agent status monitored resource expression and recent event history is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to REST API selector use, where rEST representation selection and HTTP method choice affect what configuration is retrieved or changed In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is nAE agents monitor local switch state and can correlate rule conditions over time

C:

This is relevant to UXI internal and external tests, where internal and external synthetic tests isolate distinct service paths and failure domains In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is nAE agents monitor local switch state and can correlate rule conditions over time

D:

This is relevant to Switch telemetry counters, where interface counters help distinguish physical corruption from congestion drops In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is nAE agents monitor local switch state and can correlate rule conditions over time

Question 1028

At Engineering Tower, a new switchport has electrical link but the 802.1X state is unauthorized and no user VLAN is assigned. Which controlled configuration is most likely to restore the required service?

  1. Activate and check appropriate LLDP advertisements on approved links with a verified topology map.
  2. Resolve the link-layer EAPOL authentication exchange and authorization state before DHCP debugging.
  3. Synchronize compatible speed and duplex negotiation at both Ethernet endpoints before testing traffic.
  4. Validate compatible PoE class switch power budget and negotiated per-port allocation.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is 802.1X EAPOL versus IP service. 802.1X is port-based access control; IP configuration occurs after network admission. Resolve the link-layer EAPOL authentication exchange and authorization state before DHCP debugging establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

C:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

D:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

Question 1029

At West Auditorium, an employee connects a small unmanaged switch that sends BPDUs into an edge access port. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Do not enable jumbo frames on one device without validating intermediate hops.
  2. Require human review before re-enabling a port after an unexpected BPDU.
  3. Enable BPDU guard only on appropriate edge ports with a documented recovery process.
  4. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.

Explanation

Correct Answers

B:

This is the continuing risk-control element for West Auditorium. Require human review before re-enabling a port after an unexpected BPDU prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

C:

This is the implementation element for the West Auditorium case: BPDU guard protects edge ports from becoming transit paths for unauthorized switches. The specific action Enable BPDU guard only on appropriate edge ports with a documented recovery process addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for End-to-end MTU and frames: A path's effective MTU is limited by the smallest supported segment and encapsulation overhead. It does not resolve the BPDU guard edge ports requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is bPDU guard protects edge ports from becoming transit paths for unauthorized switches

D:

This may be a configuration step for Voice VLAN LLDP-MED: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. It does not resolve the BPDU guard edge ports requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is bPDU guard protects edge ports from becoming transit paths for unauthorized switches

Question 1030

  1. Set up correct local/remote BGP AS and reachable neighbor address.
  2. Restore an authorized default next hop and deliberate route preferences.
  3. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  4. Install a valid static route with a resolvable next hop and appropriate administrative distance.

Explanation

Correct Answer

A:

For West Auditorium, the decisive mechanism is BGP neighbor ASN mismatch. BGP adjacency requires consistent peer addressing and ASN relationships. Configure correct local/remote BGP AS and reachable neighbor address establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships

D:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships
