Question 280

At Central Hall, a new campus fiber uplink should be preferred but interface costs retain old values. Which check provides the most useful information for fixing this deployment?

  1. Examine IPv6 link-local neighbors OSPFv3 interface area and router ID.
  2. Examine VRRP advertisements gateway owner and virtual MAC state.
  3. Examine SPF result per-interface cost and best-route selection.
  4. Examine relay forwarded packets GIADDR server routes and ACL logs.

Explanation

Correct Answer

C:

For Central Hall, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Inspect SPF result per-interface cost and best-route selection is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

D:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

Question 281

At Engineering Tower, a role definition changed centrally yet one switch retains an outdated local enforcement policy. Which controlled acceptance test demonstrates the required behavior?

  1. Correlate a test session and termination with the intended accounting records.
  2. Test allowed application connectivity and rejected unauthorized east-west traffic.
  3. Authenticate a test client and confirm the expected downloaded role rules actually apply.
  4. Authenticate with newly issued certificates through the whole EAP-TLS exchange.

Explanation

Correct Answer

C:

For Engineering Tower, the decisive mechanism is Downloadable user roles. Downloadable roles coordinate centrally defined access controls with capable switch enforcement. Authenticate a test client and confirm the expected downloaded role rules actually apply supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

D:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

Question 282

At Main Data Center, a branch needs to advertise a subnet but must not accept OSPF neighbors from endpoints. Which check provides the most useful information for fixing this deployment?

  1. Examine VRRP advertisements gateway owner and virtual MAC state.
  2. Examine active equal-cost routes flow hashing and actual per-link counters.
  3. Examine IPv6 link-local neighbors OSPFv3 interface area and router ID.
  4. Examine hello captures and neighbor table on the user SVI.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is Passive OSPF access VLAN. Passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised. Inspect hello captures and neighbor table on the user SVI is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

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 Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

Question 283

At Arts Pavilion, two distribution gateways both try to become master after an inconsistent VRRP priority update. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Synchronize OSPF area ID and supported area type at both neighboring interfaces.
  2. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.
  3. Establish compatible OSPF interface hello and dead intervals on both peers.
  4. Restore an authorized default next hop and deliberate route preferences.

Explanation

Correct Answer

B:

For Arts Pavilion, the decisive mechanism is First-hop gateway election. VRRP abstracts the default gateway across eligible routing devices. Configure supported VRRP with consistent virtual IP and safe priority/failover behavior establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Arts Pavilion case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

C:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Arts Pavilion case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

D:

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 Arts Pavilion case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

Question 284

At New Teaching Block, a printer MAC moves rapidly between two closet switchports during a wiring fault. What measured or witnessed result should be required before signoff?

  1. Permit a specifically authorized app and block the matching forbidden traffic.
  2. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.
  3. Fix the incorrect path and confirm one stable forwarding location for the MAC.
  4. Run controlled large-payload tests and confirm reliable path MTU behavior.

Explanation

Correct Answer

C:

For New Teaching Block, the decisive mechanism is MAC address flapping. Repeated MAC address moves often indicate a changing Layer 2 path or loop. Fix the incorrect path and confirm one stable forwarding location for the MAC supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the New Teaching Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

B:

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 New Teaching Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

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 New Teaching Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

Question 285

At Garden Hall, a new automation overwrites unspecified AOS-CX attributes by using an incomplete PUT body. Which test best differentiates real success from a merely healthy status light?

  1. Trigger a safe lab threshold and verify historical record and alert generation.
  2. Capture identifiable test traffic without dropping ordinary production forwarding.
  3. Read a test resource safely and confirm returned properties match the chosen selector.
  4. Show controlled service degradation is detected and accurately localized by UXI.

Explanation

Correct Answer

C:

For Garden Hall, the decisive mechanism is REST API selector use. REST representation selection and HTTP method choice affect what configuration is retrieved or changed. Read a test resource safely and confirm returned properties match the chosen selector supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

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 Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

D:

This is relevant to UXI client experience probes, where uXI sensors run synthetic end-user workflows to reveal service-layer failures In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

Question 286

At Athletics Complex, a 5-GHz WLAN moves channels abruptly when radar detection triggers DFS. Which controlled configuration is most likely to restore the required service?

  1. Plan DFS-eligible channel use and client expectations based on regulation and service needs.
  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 Athletics Complex, the decisive mechanism is DFS event awareness. DFS channels require radar-related channel vacating behavior in supported regions. Plan DFS-eligible channel use and client expectations based on regulation and service needs 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 Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

C:

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, Changing that neighboring feature does not implement the missing function. 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, Changing that neighboring feature does not implement the missing function. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

Question 287

At Hillcrest Campus, campus A and B use different MST region revision strings and instances act as separate regions. What safety boundary prevents the same campus failure in future deployments?

  1. Do not enable jumbo frames on one device without validating intermediate hops.
  2. Guard against arbitrary untrusted client VLAN tagging on shared ports.
  3. Stage ACL changes with console rollback to avoid management lockout.
  4. Version-control MST mappings and stage broad region changes.

Explanation

Correct Answer

D:

For Hillcrest Campus, the decisive mechanism is MST region matching. MSTP maps VLANs to spanning-tree instances inside a consistent region. Version-control MST mappings and stage broad region changes is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mSTP maps VLANs to spanning-tree instances inside a consistent region

B:

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 Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mSTP maps VLANs to spanning-tree instances inside a consistent region

C:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mSTP maps VLANs to spanning-tree instances inside a consistent region

Question 288

At Transit Operations Center, dual-band clients crowd 2.4-GHz radios despite healthy 5-GHz capacity. 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. Enable suitable band-steering behavior after checking client compatibility and RF coverage.
  3. Keep legacy 2.4-GHz-only devices connected through tested exemptions.
  4. Adjust mounting antenna orientation and power using active RF measurements.

Explanation

Correct Answers

B:

This is the implementation element for the Transit Operations Center case: Band steering guides capable clients toward suitable bands but client behavior still matters. The specific action Enable suitable band-steering behavior after checking client compatibility and RF coverage addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Transit Operations Center. Keep legacy 2.4-GHz-only devices connected through tested exemptions 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 Band steering behavior requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is band steering guides capable clients toward suitable bands but client behavior still matters

D:

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 Band steering behavior requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is band steering guides capable clients toward suitable bands but client behavior still matters

  2. Audit implicit permits and policy defaults after group membership changes.
  3. Monitor expiration windows and keep controlled rollback trust transitions.
  4. Secure log integrity retention and access according to data policy.

Explanation

Correct Answer

A:

For Innovation Studio, the decisive mechanism is WPA3 Enterprise compatibility. WPA3-Enterprise builds on supported enterprise security capabilities with stronger protections. Plan tested transition for legacy devices without weakening all WLANs is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

C:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

D:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

  1. Inspect associated bands steering outcomes and per-band utilization.
  2. Inspect input DSCP markings trust state and egress queue classification.
  3. Inspect client WMM capability TID mapping and AP access-category statistics.
  4. Inspect queue mappings weights and actual dropped/served traffic.

Explanation

Correct Answer

A:

For Engineering Tower, the decisive mechanism is Band steering under load. Band steering can guide dual-band association but depends on real RF and client support. Inspect associated bands steering outcomes and per-band utilization is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

C:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

D:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support
