Question 190

At Riverside Building, a wireless SSID has no voice prioritization so delay increases during heavy uploads. Which practical change is best suited to this topology and its constraints?

  1. Tune supported band steering with proper 5-GHz coverage and compatibility checks.
  2. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.
  3. Evaluate supported multicast conversion and membership control for the audience size.
  4. Adjust transmit power with channel plan and measured minimum edge SNR.

Explanation

Correct Answer

B:

For Riverside Building, the decisive mechanism is WMM access categories. 802.11e WMM prioritizes wireless contention via different access categories. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

C:

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

D:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

Question 191

At Garden Hall, a neighboring business uses a similar SSID and administrators want to avoid incorrect containment. Which observation most directly isolates the likely cause before any change?

  1. Examine TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Examine client TLS validation errors certificate SAN and trusted issuer store.
  3. Examine effective roles group policy and same-VLAN as well as routed flows.
  4. Examine BSSID wired connection location and authorized AP inventory.

Explanation

Correct Answer

D:

For Garden Hall, the decisive mechanism is Rogue AP response. Rogue identification differs from automatically assuming all same-name neighbor APs are malicious. Inspect BSSID wired connection location and authorized AP inventory is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

B:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

Question 192

At West Auditorium, a backup RADIUS server is configured but never used when the first server is unreachable. Which change-management constraint best guards against recurrence?

  1. Validate access-switch VLAN availability before rolling out central enforcement changes.
  2. Do not broadly fail-open protected ports on temporary RADIUS loss.
  3. Avoid shrinking timers purely for perceived security without measuring disruption.
  4. Retain emergency break-glass administration documented and monitored.

Explanation

Correct Answer

B:

For West Auditorium, the decisive mechanism is RADIUS authorization timeout. Authentication server reachability and retry order influence network-admission decisions. Do not broadly fail-open protected ports on temporary RADIUS loss is an enduring limitation on the operational risk, not simply a one-time passing test.

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 West Auditorium case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

C:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

D:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

Question 193

At Arts Pavilion, a critical voice queue experiences latency because every egress queue uses weighted round-robin. What observable outcome would prove this repair actually works?

  1. Run the target application with representative subscribers and verify latency and load.
  2. Walk test improved roaming and reduced overlap at the target busy locations.
  3. Stress uplink and confirm voice stays timely without starvation of other classes.
  4. Observe suitable dual-band clients prefer 5 GHz without breaking legacy endpoints.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is Strict priority queue use. Priority scheduling affects service latency but requires careful queue sizing. Stress uplink and confirm voice stays timely without starvation of other classes supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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 Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

B:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

D:

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 Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

Question 194

At Learning Commons, a wireless bridge connected incorrectly causes the same source MAC to appear on alternate LAG paths. Which controlled acceptance test demonstrates the required behavior?

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

Explanation

Correct Answer

D:

For Learning Commons, 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 End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the Learning Commons 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 ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Learning Commons 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

C:

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 Learning Commons 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 195

At Medical Annex, a visitor SSID is reachable but users can access internal management servers. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Inspect effective roles group policy and same-VLAN as well as routed flows.
  3. Inspect start interim and stop records mapped to the NAD and user.
  4. Inspect effective role firewall policy and guest source reachability.

Explanation

Correct Answer

D:

For Medical Annex, the decisive mechanism is Guest segmentation. Guest network segmentation depends on enforced policy, not only SSID naming. Inspect effective role firewall policy and guest source reachability is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

Question 196

At North Library, one closet advertises a different VLAN-to-instance map and causes unexpected boundary behavior. Which controlled configuration is most likely to restore the required service?

  1. Set up matching active-gateway address and MAC settings on the applicable VSX SVIs.
  2. Set up a separate reachable VSX keepalive path with valid source and peer addressing.
  3. Synchronize approved MST region name revision and VLAN-to-instance mapping among intended members.
  4. Build a supported VSX ISL with enough capacity and verify peer state consistency.

Explanation

Correct Answer

C:

For North Library, the decisive mechanism is MSTP region identity. MST region identity depends on matching configuration, not only the switch hostname. Align approved MST region name revision and VLAN-to-instance mapping among intended members 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 North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

D:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

Question 197

At Main Data Center, a high-power AP repeatedly reboots when a legacy switch port allocates insufficient PoE power. What measured or witnessed result should be required before signoff?

  1. Pass tagged test frames for the intended VLAN while proving unauthorized VLANs remain blocked.
  2. Prove the client completes association and then separately completes its enterprise authentication.
  3. Confirm 802.1X authorized state then obtain a lease on the assigned VLAN.
  4. Sustain the full AP or phone feature load without PoE budget alarms or resets.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is PoE power negotiation. 802.3af at and bt power classes and the switch budget constrain device operation. Sustain the full AP or phone feature load without PoE budget alarms or resets supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to 802.1Q VLAN tagging, where 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

B:

This is relevant to 802.11 association sequence, where 802.11 discovery and association occur before user traffic can be successfully forwarded In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

C:

This is relevant to 802.1X EAPOL versus IP service, where 802.1X is port-based access control; IP configuration occurs after network admission In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

Question 198

At Convention Center, an attached device triggers excessive broadcast traffic that saturates a low-speed access link. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect untagged packet capture and both peers native VLAN configuration.
  2. Compare allowed VLAN list tagging and egress counters at both ends.
  3. Inspect interface VLAN mode learned MAC address and DHCP lease subnet.
  4. Compare broadcast multicast rate and threshold/drop counters during the incident.

Explanation

Correct Answer

D:

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. Compare broadcast multicast rate and threshold/drop counters during the incident is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

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 Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

Question 199

At Main Data Center, a high-power AP repeatedly reboots when a legacy switch port allocates insufficient PoE power. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Maintain reserve PoE capacity and recheck the budget during AP model changes.
  2. Permit the required 802.1Q VLAN tags at both trunk ends and map the correct native VLAN.
  3. Retain RADIUS failover and a defined restricted fallback for the expected device class.
  4. Validate compatible PoE class switch power budget and negotiated per-port allocation.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Main Data Center. Maintain reserve PoE capacity and recheck the budget during AP model changes prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

D:

This is the implementation element for the Main Data Center case: 802.3af at and bt power classes and the switch budget constrain device operation. The specific action Validate compatible PoE class switch power budget and negotiated per-port allocation addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be a configuration step for 802.1Q VLAN tagging: 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links. It does not resolve the PoE power negotiation requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is 802.3af at and bt power classes and the switch budget constrain device operation

C:

This may be an ongoing precaution for 802.1X EAPOL versus IP service: 802.1X is port-based access control; IP configuration occurs after network admission. It does not resolve the PoE power negotiation requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is 802.3af at and bt power classes and the switch budget constrain device operation

Question 200

At Hillcrest Campus, an AP 6 GHz radio never activates while PoE is negotiated at a low class. Which controlled configuration is most likely to restore the required service?

  1. Verify subscription device identity Central assignment and management reachability in the authorized tenant.
  2. Supply supported PoE class and verify available per-port and total chassis power budget.
  3. Add an authorized management-VRF route and correct source reachability for the target service.
  4. Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.

Explanation

Correct Answer

B:

For Hillcrest Campus, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Supply supported PoE class and verify available per-port and total chassis power budget 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 Hillcrest Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

C:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

D:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations
