Question 1160

At Main Data Center, a university deployed 80-MHz 5-GHz channels to maximize single-client rates but dense classrooms now collide. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Select narrower supported channel width when needed for density and clean frequency reuse.
  2. Evaluate capacity not merely highest advertised PHY rate.
  3. Keep guest clients isolated from internal networks throughout portal state changes.
  4. Adjust mounting antenna orientation and power using active RF measurements.

Explanation

Correct Answers

A:

This is the implementation element for the Main Data Center case: Wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs. The specific action Select narrower supported channel width when needed for density and clean frequency reuse addresses the stated fault; the question also requires a persistent risk control.

B:

This is the continuing risk-control element for Main Data Center. Evaluate capacity not merely highest advertised PHY rate prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

C:

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 Channel width in density requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

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 Channel width in density requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

Question 1161

At West Clinic, a network access team rotates ClearPass server certificates but misses trust distribution. Which controlled configuration is most likely to restore the required service?

  1. Coordinate valid certificate chain rotation and trust propagation before expiry.
  2. Choose supported WPA3-Enterprise settings and validated client capability before rollout.
  3. Apply supported PMF policy consistent with WLAN security and client capabilities.
  4. Return and enforce the correct identity-based role or VLAN through ClearPass and access infrastructure.

Explanation

Correct Answer

A:

For West Clinic, the decisive mechanism is Certificate renewal workflow. Authentication availability depends on valid certificate lifecycle at both ends. Coordinate valid certificate chain rotation and trust propagation before expiry establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

C:

This is relevant to Protected management frames, where protected management frames reduce forgery of eligible robust management frames In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

D:

This is relevant to ClearPass role-based enforcement, where clearPass decides authorization outcomes while network devices enforce assigned policy In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

Question 1162

At East Student Center, a CX switch interface flaps intermittently and the NOC wants local time-series evidence. Which preventive control is most relevant to this scenario over time?

  1. Position sensors where representative users connect and manage test credentials safely.
  2. Apply tested scripts with supported permissions and avoid uncontrolled remediation actions.
  3. Grant least-privilege API access and back up intended modifications.
  4. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.

Explanation

Correct Answer

B:

For East Student Center, the decisive mechanism is NAE monitor rule. NAE agents monitor local switch state and can correlate rule conditions over time. Use tested scripts with supported permissions and avoid uncontrolled remediation actions is an enduring limitation on the operational risk, not simply a one-time passing test.

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 East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is nAE agents monitor local switch state and can correlate rule conditions over time

C:

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, A precaution for another failure mode is not the enduring boundary needed here. 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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is nAE agents monitor local switch state and can correlate rule conditions over time

Question 1163

At Riverside Building, an AP on a PoE trunk receives power but lacks a route to Central discovery services. Which controlled configuration is most likely to restore the required service?

  1. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  2. Establish the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  3. Add an authorized management-VRF route and correct source reachability for the target service.
  4. Bind the device to its approved group and review group-level settings and local overrides.

Explanation

Correct Answer

B:

For Riverside Building, the decisive mechanism is AP uplink physical mapping. AP service onboarding depends on both physical power and the upstream management network. Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

C:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

D:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

Question 1164

At West Auditorium, a dense enterprise WLAN needs advisory roam guidance without hard-disconnecting phones. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Cross-check spatial signal maps channel overlap and client roaming behavior.
  2. Examine cluster health tunnel termination count CPU and per-member forwarding.
  3. Examine portal redirect RADIUS or guest authorization events and the effective client role.
  4. Examine BSS transition request/response frames and chosen candidate BSSID.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is 802.11v BSS transition. 802.11v can suggest a transition; the client retains a role in the roaming decision. Inspect BSS transition request/response frames and chosen candidate BSSID is the most direct way to isolate this particular failure before making a change.

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 West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

Question 1165

At North Library, an ArubaOS 10 gateway cluster has one unavailable member and remaining devices hit client-capacity ceilings. Which observation most directly isolates the likely cause before any change?

  1. Compare RSSI noise floor SNR and retransmissions per affected client.
  2. Inspect surveyed RSSI SNR channel use and roaming measurements at user positions.
  3. Inspect co-channel AP visibility airtime utilization and contention counters.
  4. Inspect cluster health tunnel termination count CPU and per-member forwarding.

Explanation

Correct Answer

D:

For North Library, the decisive mechanism is Gateway cluster resiliency. Tunneled service resilience requires usable gateway capacity and working AP tunnels. Inspect cluster health tunnel termination count CPU and per-member forwarding is the most direct way to isolate this particular failure before making a change.

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 North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

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 North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

Question 1166

At Athletics Complex, an AOS-CX switch pings the Internet in default VRF but cannot reach its management NTP server. How should the engineer validate success against the stated requirement?

  1. See the AP obtain correct management addressing and report online in Central.
  2. Capture a test client flow at its designated wired VLAN or gateway policy point.
  3. Reach the approved server from the intended management interface without leaking access VLANs.
  4. Confirm both intended members distribute traffic and single-member loss is tolerated.

Explanation

Correct Answer

C:

For Athletics Complex, the decisive mechanism is Management VRF reachability. AOS-CX management VRF and default forwarding VRF may have separate reachability. Reach the approved server from the intended management interface without leaking access VLANs supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

B:

This is relevant to Bridge versus tunneled WLAN traffic, where bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

D:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

Question 1167

At Convention Center, an attached device triggers excessive broadcast traffic that saturates a low-speed access link. Which controlled configuration is most likely to restore the required service?

  1. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  2. Align native VLAN configuration and avoid using native VLAN for untrusted access where possible.
  3. Apply appropriate storm-control thresholds on eligible access ports without hiding topology issues.
  4. Set the switchport as an access member of the correct VLAN with matching policy.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is Broadcast storm control. Storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops. Apply appropriate storm-control thresholds on eligible access ports without hiding topology issues establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

B:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

D:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

Question 1168

At Main Data Center, an AP group uses overly broad management roles during contractor onboarding. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Apply least privilege and log management configuration changes.
  2. Restrict management-plane reachability and privileges to authorized VRFs roles and hosts.
  3. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.
  4. Never direct users to blindly accept arbitrary authentication server certificates.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Main Data Center. Apply least privilege and log management configuration changes prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

B:

This is the implementation element for the Main Data Center case: Data-plane forwarding policy does not automatically secure device management services. The specific action Restrict management-plane reachability and privileges to authorized VRFs roles and hosts addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

C:

This may be a configuration step for EAP-TLS client certificate validation: EAP-TLS authenticates possession of the client certificate private key and validates trust. It does not resolve the Management plane protection requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is data-plane forwarding policy does not automatically secure device management services

D:

This may be an ongoing precaution for EAP-TLS RADIUS server certificate: Mutual TLS requires client-side confidence in the EAP server identity. It does not resolve the Management plane protection requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is data-plane forwarding policy does not automatically secure device management services

Question 1169

At North Residence, a campus edge advertises a private management prefix to its ISP by mistake. Which investigation most directly explains why the intended service is not working?

  1. Inspect OSPF hello packet area values network type and adjacency state.
  2. Inspect route table recursive next-hop resolution and ARP reachability.
  3. Compare default prefixes distances next-hop health and forwarding decisions.
  4. Inspect exported prefix list evaluation and neighbor advertised-routes.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is BGP prefix filtering. BGP route filters control prefix advertisement and must account for length matching. Inspect exported prefix list evaluation and neighbor advertised-routes is the most direct way to isolate this particular failure before making a change.

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 North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

B:

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 North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

C:

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 North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

Question 1170

At East Student Center, a distribution policy blocks return traffic after a stateless ACL is attached to the wrong SVI direction. What should be examined to confirm the actual failure mechanism?

  1. Examine interface VLAN mode learned MAC address and DHCP lease subnet.
  2. Cross-check allowed VLAN list tagging and egress counters at both ends.
  3. Examine untagged packet capture and both peers native VLAN configuration.
  4. Examine hit counters rule ordering and packet direction for a controlled flow.

Explanation

Correct Answer

D:

For East Student Center, the decisive mechanism is ACL direction and interface. Stateless ACL effectiveness depends on interface attachment direction and rule order. Inspect hit counters rule ordering and packet direction for a controlled flow is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order

B:

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 East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order

C:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order
