Question 460

At West Auditorium, a backup RADIUS server is configured but never used when the first server is unreachable. What observable outcome would prove this repair actually works?

  1. Demonstrate permitted NOC commands work and prohibited configuration commands fail.
  2. Demonstrate a test contractor receives the correct restricted VLAN and no employee services.
  3. Block the primary in a lab and verify configured fallback behavior.
  4. Preserve authenticated sessions through the expected timer cycle in a controlled test.

Explanation

Correct Answer

C:

For West Auditorium, the decisive mechanism is RADIUS authorization timeout. Authentication server reachability and retry order influence network-admission decisions. Block the primary in a lab and verify configured fallback behavior supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

B:

This is relevant to Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

D:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

Question 461

At Garden Hall, an NMS queries switch CPU but interface counters remain zero after a device replacement. What targeted evidence should the network engineer collect first?

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

Explanation

Correct Answer

B:

For Garden Hall, 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 Garden Hall 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 Port mirroring PCAP, where port mirroring copies selected frames for observation but is not a live forwarding path In the Garden Hall 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

D:

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, 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 462

At New Teaching Block, voice handsets lose call continuity during long full-authentication roams. What recurring protection should accompany this configuration?

  1. Avoid compensating for poor placement only by increasing transmit power.
  2. Repeat surveys after major layout or material changes rather than trusting only plans.
  3. Keep guest clients isolated from internal networks throughout portal state changes.
  4. Stage FT changes with application and device compatibility tests.

Explanation

Correct Answer

D:

For New Teaching Block, the decisive mechanism is 802.11r fast transition. 802.11r enables fast BSS transition to shorten supported reauthentication during roaming. Stage FT changes with application and device compatibility tests is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the New Teaching Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

B:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the New Teaching Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the New Teaching Block case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

Question 463

At Riverside Building, a sensor WLAN carries many short uplink messages and needs efficient 802.11ax resource sharing. Which observation most directly isolates the likely cause before any change?

  1. Examine client capability allocation behavior and channel utilization rather than only Wi-Fi label.
  2. Examine surveyed RSSI SNR channel use and roaming measurements at user positions.
  3. Cross-check RSSI noise floor SNR and retransmissions per affected client.
  4. Examine co-channel AP visibility airtime utilization and contention counters.

Explanation

Correct Answer

A:

For Riverside Building, the decisive mechanism is OFDMA efficiency. OFDMA divides channel resources among eligible simultaneous users. Inspect client capability allocation behavior and channel utilization rather than only Wi-Fi label is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

C:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

D:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

Question 464

At Transit Operations Center, a cloned distribution switch shares an OSPF router ID and adjacency becomes unstable. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Enable matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Use supported ECMP and account for session hash distribution across eligible paths.
  3. Configure 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 Transit Operations Center, 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 Transit Operations Center 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 Transit Operations Center 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 Transit Operations Center 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 465

At Research Hub, an untrusted access client sets voice priority on bulk uploads and congests a priority queue. 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. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  4. Evaluate supported multicast conversion and membership control for the audience size.

Explanation

Correct Answer

C:

For Research Hub, the decisive mechanism is DSCP trust boundary. QoS trust boundaries determine which received packet markings affect forwarding priority. Classify trusted voice and remark untrusted DSCP at the correct campus boundary 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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

Question 466

At Technology Center, a lobby guest VLAN shares unrestricted routing with employee printers. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Apply a guest-only policy or role restricting internal routes while allowing approved Internet service.
  2. Enforce role or group-based segmentation at the supported switching/gateway point.
  3. Preserve separation even before captive-portal authentication completes.
  4. Secure CA trust and plan certificate renewal before deployment deadlines.

Explanation

Correct Answers

A:

This is the implementation element for the Technology Center case: Guest network segmentation depends on enforced policy, not only SSID naming. The specific action Apply a guest-only policy or role restricting internal routes while allowing approved Internet service addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Technology Center. Maintain separation even before captive-portal authentication completes 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 Campus microsegmentation: Role-based segmentation can limit lateral flows beyond simple VLAN separation. It does not resolve the Guest segmentation requirement in Technology Center and is not one of the two controls requested. The direct mechanism here is guest network segmentation depends on enforced policy, not only SSID naming

D:

This may be an ongoing precaution for EAP-TLS client certificate validation: EAP-TLS authenticates possession of the client certificate private key and validates trust. It does not resolve the Guest segmentation requirement in Technology Center and is not one of the two controls requested. The direct mechanism here is guest network segmentation depends on enforced policy, not only SSID naming

Question 467

  3. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  4. Tune supported band steering with proper 5-GHz coverage and compatibility checks.

Explanation

Correct Answer

D:

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. Tune supported band steering with proper 5-GHz coverage and compatibility checks establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

B:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

C:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support
