Question 490

At West Clinic, a trunk between two AOS-CX switches loses WLAN guest VLAN traffic after a template update. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  2. Apply the appropriate permit/deny order and direction on the data-path interface.
  3. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  4. Align MTU and encapsulation requirements across the complete supported forwarding path.

Explanation

Correct Answer

C:

For West Clinic, the decisive mechanism is Tagged trunk allowlist. A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Voice VLAN LLDP-MED, where lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

B:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

D:

This is relevant to End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

Question 491

At Transit Operations Center, a lab switch becomes root after a new access switch with a lower bridge ID is added. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Audit root priorities and use guard features on user-facing ports.
  2. Do not enable jumbo frames on one device without validating intermediate hops.
  3. Set approved bridge priorities and root guard behavior to maintain intended topology.
  4. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Transit Operations Center. Audit root priorities and use guard features on user-facing ports 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 Transit Operations Center case: Spanning Tree selects the root by bridge ID and derives loop-free port roles. The specific action Set approved bridge priorities and root guard behavior to maintain intended topology addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

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 STP root optimization requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is spanning Tree selects the root by bridge ID and derives loop-free port roles

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 STP root optimization requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is spanning Tree selects the root by bridge ID and derives loop-free port roles

Question 492

At South Science Wing, a data uplink shows increasing egress queue drops during backup windows. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Adjust transmit power with channel plan and measured minimum edge SNR.
  2. Tune supported band steering with proper 5-GHz coverage and compatibility checks.
  3. Investigate bursty egress congestion and use supported queue/buffer or capacity controls.
  4. Evaluate supported multicast conversion and membership control for the audience size.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is Congestion buffer drops. Short congestion bursts can exhaust queues before low-frequency monitoring notices. Investigate bursty egress congestion and use supported queue/buffer or capacity controls establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

B:

This is relevant to Band steering under load, where band steering can guide dual-band association but depends on real RF and client support In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

D:

This is relevant to Multicast-to-unicast tradeoff, where multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

Question 493

At Hillcrest Campus, a dense library has equal packet counts but very unequal airtime usage across client generations. What operational rule should remain in place for later changes?

  1. Repeat surveys after major layout or material changes rather than trusting only plans.
  2. Track both RF signal and noise as part of acceptance tests.
  3. Do not starve essential low-rate devices solely to maximize aggregate throughput.
  4. Avoid compensating for poor placement only by increasing transmit power.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Airtime fairness. Wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity. Do not starve essential low-rate devices solely to maximize aggregate throughput is an enduring limitation on the operational risk, not simply a one-time passing test.

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 Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

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 Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

Question 494

At Hillcrest Campus, two campus edge devices show TCP port 179 open but BGP never reaches Established. Which test best differentiates real success from a merely healthy status light?

  1. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  2. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid.
  3. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  4. Confirm Established session and expected received prefix count.

Explanation

Correct Answer

D:

For Hillcrest Campus, the decisive mechanism is BGP neighbor ASN mismatch. BGP adjacency requires consistent peer addressing and ASN relationships. Confirm Established session and expected received prefix count supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships

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 Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships

C:

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 Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP adjacency requires consistent peer addressing and ASN relationships

Question 495

At Athletics Complex, a user role updates correctly but accounting stop events are absent from the collector. How should the engineer validate success against the stated requirement?

  1. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  2. Validate enterprise clients join securely with accepted ciphers and certificates.
  3. Correlate a test session and termination with the intended accounting records.
  4. Check clients securely verify the intended RADIUS server before joining.

Explanation

Correct Answer

C:

For Athletics Complex, the decisive mechanism is RADIUS accounting traceability. Authentication and accounting provide different information and require separate configuration. Correlate a test session and termination with the intended accounting records 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 Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication and accounting provide different information and require separate configuration

B:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication and accounting provide different information and require separate configuration

D:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication and accounting provide different information and require separate configuration

Question 496

At Engineering Tower, a monitoring collector cannot poll an AOS-CX mgmt VRF with correct SNMP credentials. Which investigation most directly explains why the intended service is not working?

  1. Examine each synthetic step and route from the sensor's actual network.
  2. Examine active mirror state source interface and capture interface counters.
  3. Examine NAE agent status monitored resource expression and recent event history.
  4. Examine SNMP access policy source VRF and counter availability.

Explanation

Correct Answer

D:

For Engineering Tower, the decisive mechanism is SNMP telemetry validation. SNMP monitoring depends on reachable agents permitted OIDs and secure transport. Inspect SNMP access policy source VRF and counter availability is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to UXI internal and external tests, where internal and external synthetic tests isolate distinct service paths and failure domains In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is sNMP monitoring depends on reachable agents permitted OIDs and secure transport

B:

This is relevant to Port mirroring PCAP, where port mirroring copies selected frames for observation but is not a live forwarding path In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is sNMP monitoring depends on reachable agents permitted OIDs and secure transport

C:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is sNMP monitoring depends on reachable agents permitted OIDs and secure transport

Question 497

At Athletics Complex, a 5-GHz WLAN moves channels abruptly when radar detection triggers DFS. What recurring protection should accompany this configuration?

  1. Keep guest clients isolated from internal networks throughout portal state changes.
  2. Retain rollout headroom and test gateway interoperability during upgrades.
  3. Never suppress required regulatory radar protections for convenience.
  4. Avoid compensating for poor placement only by increasing transmit power.

Explanation

Correct Answer

C:

For Athletics Complex, the decisive mechanism is DFS event awareness. DFS channels require radar-related channel vacating behavior in supported regions. Never suppress required regulatory radar protections for convenience is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

Question 498

At Athletics Complex, a campus pair identifies two independent routing processes using an identical router ID. Which practical change is best suited to this topology and its constraints?

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Apply supported ECMP and account for session hash distribution across eligible paths.
  3. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.
  4. Assign unique router IDs and refresh OSPF process state where needed.

Explanation

Correct Answer

D:

For Athletics Complex, the decisive mechanism is OSPF router ID uniqueness. An OSPF router ID identifies a routing instance independently of VLAN labels. Assign unique router IDs and refresh OSPF process state where needed establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

B:

This is relevant to ECMP next-hop selection, where eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

C:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

Question 499

At Innovation Studio, a campus AP bridges the corporate WLAN locally but the security team expects gateway inspection. Which controlled configuration is most likely to restore the required service?

  1. Perform an active site survey covering attenuation interference and realistic client density.
  2. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  3. Use an RF plan with reasonable channel reuse and channel width for expected density.
  4. Set the correct AOS 10 bridge-mode VLAN mapping and deploy enforcement at the chosen edge.

Explanation

Correct Answer

D:

For Innovation Studio, the decisive mechanism is AOS 10 bridge forwarding. Bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway. Set the correct AOS 10 bridge-mode VLAN mapping and deploy enforcement at the chosen edge establishes the needed configuration in the case rather than merely measuring a symptom.

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 Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

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 Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

C:

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 bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

Question 500

  1. Avoid starving an approved low-rate medical or industrial device.
  2. Rate-limit or police untrusted high-priority markings.
  3. Do not blindly trust endpoint priority markings on public access ports.
  4. Preserve consistent DSCP-to-WMM mapping end to end.

Explanation

Correct Answer

A:

For East Student Center, the decisive mechanism is Airtime fairness QoS. Wireless performance must account for airtime occupancy as a shared resource. Avoid starving an approved low-rate medical or industrial device is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

C:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

D:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource
