Question 830

At Engineering Tower, a corridor shows acceptable signal strength but voice calls break amid elevated background noise. What should the engineer implement first to correct the stated condition?

  1. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  2. Apply supported clustered gateway configuration with capacity and software-version compatibility.
  3. Establish the correct AOS 10 bridge-mode VLAN mapping and deploy enforcement at the chosen edge.
  4. Map tunneled SSID to the supported gateway cluster and verify tunnel/service route policy.

Explanation

Correct Answer

A:

For Engineering Tower, the decisive mechanism is RSSI and SNR differentiation. SNR accounts for interference floor; RSSI alone does not predict useful wireless throughput. Investigate noise/interference and target adequate SNR rather than raising AP power blindly establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

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

C:

This is relevant to AOS 10 bridge forwarding, where bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput

D:

This is relevant to AOS 10 tunnel forwarding, where tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput

Question 831

At Learning Commons, a mobile scanner pauses while searching the full channel list for roaming candidates. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Enable appropriate 802.11k neighbor report support on the intended enterprise WLAN.
  2. Use supported clustered gateway configuration with capacity and software-version compatibility.
  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

A:

For Learning Commons, the decisive mechanism is 802.11k neighbor information. 802.11k provides radio-resource neighbor information to assist client decisions. Enable appropriate 802.11k neighbor report support on the intended enterprise WLAN establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

Question 832

At Riverside Building, a streaming classroom sees multicast stop when the only IGMP querier disappears. How should the engineer validate success against the stated requirement?

  1. Join one stream from approved receiver and verify forwarding only to subscriber ports.
  2. See device traffic only in its assigned broadcast domain and expected address scope.
  3. Check untagged test frames land in the same approved VLAN at both endpoints.
  4. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.

Explanation

Correct Answer

A:

For Riverside Building, the decisive mechanism is IGMP multicast snooping. IGMP snooping constrains IPv4 multicast by observed group memberships. Join one stream from approved receiver and verify forwarding only to subscriber ports supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is iGMP snooping constrains IPv4 multicast by observed group memberships

C:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is iGMP snooping constrains IPv4 multicast by observed group memberships

D:

This is relevant to Tagged trunk allowlist, where a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is iGMP snooping constrains IPv4 multicast by observed group memberships

Question 833

At Administration Block, two AOS-CX switches connect physically but never form OSPF adjacency because area IDs differ. Which change-management constraint best guards against recurrence?

  1. Audit IPv4/IPv6 protocol operation separately rather than assuming dual-stack parity.
  2. Test preemption and split-brain behavior during a controlled pilot.
  3. Check return-path symmetry and middlebox state before broad ECMP changes.
  4. Review area settings as paired changes and preserve routing rollback.

Explanation

Correct Answer

D:

For Administration Block, the decisive mechanism is OSPF area membership. OSPF neighbors on a link must agree on essential area and protocol parameters. Review area settings as paired changes and preserve routing rollback is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Administration Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Administration Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

C:

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 Administration Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

Question 834

At Bayside Campus, the policy team cannot trace which staff device used a port during an incident. Which investigation most directly explains why the intended service is not working?

  1. Inspect session IDs accounting messages timestamps and NAS identity.
  2. Inspect Access-Accept AV pairs and effective port role or VLAN assignment.
  3. Inspect server status transport timeouts and alternate server selection.
  4. Inspect EAPOL handshake switch authentication state and RADIUS responses.

Explanation

Correct Answer

A:

For Bayside Campus, the decisive mechanism is RADIUS accounting for audit. AAA accounting tracks session use separately from authentication and authorization. Inspect session IDs accounting messages timestamps and NAS identity is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

D:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

Question 835

At Garden Hall, an unmanaged switch creates a physical loop downstream of an edge closet. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect loop-protect logs MAC flapping and abnormal broadcast traffic.
  2. Inspect ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  3. Inspect keepalive reachability and failure signals independently of ISL health.
  4. Compare configured and operational gateway state and ARP entries on both VSX peers.

Explanation

Correct Answer

A:

For Garden Hall, the decisive mechanism is Loop protection. Loop detection complements STP by containing accidental edge loops. Inspect loop-protect logs MAC flapping and abnormal broadcast traffic is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

C:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

Question 836

At Main Data Center, an IoT VLAN has an ACL but still reaches finance servers through an unintended routed path. What measured or witnessed result should be required before signoff?

  1. Confirm clients securely verify the intended RADIUS server before joining.
  2. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  3. Test approved media flows and blocked finance-server access.
  4. Validate enterprise clients join securely with accepted ciphers and certificates.

Explanation

Correct Answer

C:

For Main Data Center, the decisive mechanism is Access ACL segmentation. A policy object is effective only where attached to the forwarding path. Test approved media flows and blocked finance-server access supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a policy object is effective only where attached to the forwarding path

B:

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 Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a policy object is effective only where attached to the forwarding path

D:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a policy object is effective only where attached to the forwarding path

Question 837

At West Auditorium, high-density APs show uneven client counts despite similar neighbor RF conditions. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Keep guest clients isolated from internal networks throughout portal state changes.
  2. Apply supported ClientMatch optimization with measured AP and client behavior.
  3. Adjust mounting antenna orientation and power using active RF measurements.
  4. Do not enforce moves to weak neighboring radios merely to balance numbers.

Explanation

Correct Answers

B:

This is the implementation element for the West Auditorium case: ClientMatch can guide client association and roaming decisions based on RF and load. The specific action Apply supported ClientMatch optimization with measured AP and client behavior addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for West Auditorium. Do not enforce moves to weak neighboring radios merely to balance numbers 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 Guest portal and role: Captive portal authentication and post-login role enforcement are separate controls. It does not resolve the ClientMatch balancing requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is clientMatch can guide client association and roaming decisions based on RF and load

C:

This may be a configuration step for AP power and cell geometry: AP placement and transmit power affect cell coverage and roaming boundaries. It does not resolve the ClientMatch balancing requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is clientMatch can guide client association and roaming decisions based on RF and load

Question 838

At Technology Center, a trunk to a campus AP forwards staff frames but guest frames on VLAN 230 never reach the distribution switch. What safety boundary prevents the same campus failure in future deployments?

  1. Preserve approved transceiver and link-setting baselines for any future port migration.
  2. Record VLAN allowlists and avoid a global all-VLAN trunk as a shortcut.
  3. Maintain reserve PoE capacity and recheck the budget during AP model changes.
  4. Restrict sensitive management details on ports where topology advertisement is inappropriate.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is 802.1Q VLAN tagging. 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links. Record VLAN allowlists and avoid a global all-VLAN trunk as a shortcut is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

C:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

D:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

Question 839

At Transit Operations Center, a distribution ABR advertises overly broad summary and blackholes an unallocated subnet. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Create appropriate OSPF area range summaries at a supported ABR boundary.
  3. Install a valid static route with a resolvable next hop and appropriate administrative distance.
  4. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.

Explanation

Correct Answer

B:

For Transit Operations Center, the decisive mechanism is OSPF area aggregation. OSPF area summarization reduces route detail but can hide gaps in address plans. Create appropriate OSPF area range summaries at a supported ABR boundary 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 Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

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 Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

Question 840

At Research Hub, slow legacy clients monopolize airtime in a busy classroom WLAN. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Tune supported airtime-fairness behavior based on client mix and user experience.
  2. Perform an active site survey covering attenuation interference and realistic client density.
  3. Track both RF signal and noise as part of acceptance tests.
  4. Do not starve essential low-rate devices solely to maximize aggregate throughput.

Explanation

Correct Answers

A:

This is the implementation element for the Research Hub case: Wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity. The specific action Tune supported airtime-fairness behavior based on client mix and user experience addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Research Hub. Do not starve essential low-rate devices solely to maximize aggregate throughput prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

B:

This may be a configuration step for RF predictive versus active survey: Predictive RF planning does not replace measured real-world attenuation and utilization. It does not resolve the Airtime fairness requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

C:

This may be an ongoing precaution for RSSI and SNR differentiation: SNR accounts for interference floor; RSSI alone does not predict useful wireless throughput. It does not resolve the Airtime fairness requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity
