Question 290

At Engineering Tower, 5-GHz-capable clients remain on congested 2.4 GHz even where 5 GHz is strong. Which check provides the most useful information for fixing this deployment?

  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

Question 291

At Technology Center, two gateway peers advertise inconsistent VRRP virtual IP settings after maintenance. What operational rule should remain in place for later changes?

  1. Validate shared virtual gateway settings on both peers before activating a new VLAN.
  2. Test preemption and split-brain protection before changing gateway priority.
  3. Secure ISL paths and preserve independent keepalive failure domains.
  4. Retain keepalive routing isolated from routine campus policy edits.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is VRRP redundant gateway. VRRP supplies virtual first-hop gateway failover between eligible routing peers. Test preemption and split-brain protection before changing gateway priority is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

D:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

Question 292

At Transit Operations Center, a managed workstation receives Access-Reject despite a valid password after certificate renewal. Which practical change is best suited to this topology and its constraints?

  1. Correct STP root priorities and protect edge or downstream boundaries as appropriate.
  2. Correct SSID-to-VLAN and switch trunk membership for the intended segment.
  3. Review the specific ClearPass service match authentication source and TLS decision.
  4. Trace the forward and reverse forwarding path including route recursion and ACLs.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is RADIUS Access-Reject root cause. An explicit RADIUS reject can come from credential validation or authorization policy. Review the specific ClearPass service match authentication source and TLS decision establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

B:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

D:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Transit Operations Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

Question 293

At Hillcrest Campus, a building badge reader must be admitted with restricted access despite lacking EAP-TLS capability. Which test best differentiates real success from a merely healthy status light?

  1. Demonstrate a test contractor receives the correct restricted VLAN and no employee services.
  2. Demonstrate permitted NOC commands work and prohibited configuration commands fail.
  3. Demonstrate the registered headless device gets its narrow role while an unknown MAC is denied.
  4. Preserve authenticated sessions through the expected timer cycle in a controlled test.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is MAB for headless IoT. MAB is a weaker fallback identity mechanism than certificate-based 802.1X. Verify the registered headless device gets its narrow role while an unknown MAC is denied supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

B:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

D:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

Question 294

At Administration Block, wireless clients disconnect when a single tunnel gateway goes offline despite multiple gateways being deployed. What should the engineer implement first to correct the stated condition?

  1. Configure matching active-gateway address and MAC settings on the applicable VSX SVIs.
  2. Configure a separate reachable VSX keepalive path with valid source and peer addressing.
  3. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  4. Create a compatible gateway cluster with capacity and mobility requirements in Central.

Explanation

Correct Answer

D:

For Administration Block, the decisive mechanism is AOS 10 gateway cluster. An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. Create a compatible gateway cluster with capacity and mobility requirements in Central establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

Question 295

At Hillcrest Campus, an AP 6 GHz radio never activates while PoE is negotiated at a low class. What recurring protection should accompany this configuration?

  1. Treat AP port changes as staged network access changes rather than bypassing admission.
  2. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  3. Budget power headroom and check switch model support before adding higher-power APs.
  4. Use controlled serial-number ownership checks and avoid blindly claiming unknown devices.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Budget power headroom and check switch model support before adding higher-power APs is an enduring limitation on the operational risk, not simply a one-time passing test.

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 Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

B:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

D:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Hillcrest Campus case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

Question 296

At North Library, an administrator sets a WPA3-only enterprise WLAN but some authorized handhelds lack required support. What measured or witnessed result should be required before signoff?

  1. Correlate a test session and termination with the intended accounting records.
  2. Authenticate with newly issued certificates through the whole EAP-TLS exchange.
  3. Test allowed application connectivity and rejected unauthorized east-west traffic.
  4. Validate enterprise clients join securely with accepted ciphers and certificates.

Explanation

Correct Answer

D:

For North Library, the decisive mechanism is WPA3 Enterprise compatibility. WPA3-Enterprise builds on supported enterprise security capabilities with stronger protections. Validate enterprise clients join securely with accepted ciphers and certificates 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 North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

B:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the North Library case, That test could pass while the actual user-facing requirement still fails.

  1. Inspect client TLS validation errors certificate SAN and trusted issuer store.
  2. Inspect association RSN capability and failed security negotiation status.
  3. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  4. Inspect match counters packet path and route bypass around the intended ACL.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is Access ACL segmentation. A policy object is effective only where attached to the forwarding path. Inspect match counters packet path and route bypass around the intended ACL is the most direct way to isolate this particular failure before making a change.

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, Those observations could be normal while the stated fault persists. The specific mechanism is a policy object is effective only where attached to the forwarding path

B:

  1. Confirm coverage and capacity with representative real devices and occupancy.
  2. Observe lower airtime contention and stable throughput during concurrent client use.
  3. Measure improved SNR and reduced retry rate without oversizing transmit power.
  4. Verify essential SSIDs remain visible and overall airtime use decreases.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is Excessive SSID beacon overhead. Each advertised SSID sends management traffic that consumes shared airtime. Verify essential SSIDs remain visible and overall airtime use decreases supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is each advertised SSID sends management traffic that consumes shared airtime

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is each advertised SSID sends management traffic that consumes shared airtime
