Question 970

At Central Hall, a school EAP-TLS service stops accepting clients after the intermediate CA expires. What should the engineer implement first to correct the stated condition?

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

Explanation

Correct Answer

B:

For Central Hall, 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

A:

This is relevant to ClearPass role-based enforcement, where clearPass decides authorization outcomes while network devices enforce assigned policy In the Central Hall 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 Central Hall 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 WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Central Hall 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 971

At Main Data Center, an IoT VLAN has an ACL but still reaches finance servers through an unintended routed path. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Apply reviewed permit/deny ACL or role policy at the actual forwarding enforcement point.
  2. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.
  3. Never direct users to blindly accept arbitrary authentication server certificates.
  4. Preserve management and emergency access during ACL changes.

Explanation

Correct Answers

A:

This is the implementation element for the Main Data Center case: A policy object is effective only where attached to the forwarding path. The specific action Apply reviewed permit/deny ACL or role policy at the actual forwarding enforcement point addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Main Data Center. Preserve management and emergency access during ACL changes 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 EAP-TLS client certificate validation: EAP-TLS authenticates possession of the client certificate private key and validates trust. It does not resolve the Access ACL segmentation requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is a policy object is effective only where attached to the forwarding path

C:

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 Access ACL segmentation requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is a policy object is effective only where attached to the forwarding path

Question 972

At Lakeside Classroom, a topology change moves the root toward a low-bandwidth edge switch. What operational rule should remain in place for later changes?

  1. Guard root-sensitive ports against superior BPDUs from downstream devices.
  2. Retain keepalive routing isolated from routine campus policy edits.
  3. Secure ISL paths and preserve independent keepalive failure domains.
  4. Validate shared virtual gateway settings on both peers before activating a new VLAN.

Explanation

Correct Answer

A:

For Lakeside Classroom, the decisive mechanism is RSTP root placement. RSTP uses a root bridge and port roles to build a loop-free Layer 2 topology. Guard root-sensitive ports against superior BPDUs from downstream devices is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

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 Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

Question 973

At Learning Commons, a mobile scanner pauses while searching the full channel list for roaming candidates. How should the engineer validate success against the stated requirement?

  1. Verify pre-auth restrictions then post-auth Internet-only reachability.
  2. Fail one member under a staged load and confirm expected client access.
  3. Confirm the client receives useful neighbor data and reduces roam scanning time.
  4. Measure acceptable coverage plus SNR at walking and seated client locations.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is 802.11k neighbor information. 802.11k provides radio-resource neighbor information to assist client decisions. Confirm the client receives useful neighbor data and reduces roam scanning time supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

Question 974

At Research Hub, slow legacy clients monopolize airtime in a busy classroom WLAN. What should be examined to confirm the actual failure mechanism?

  1. Compare spatial signal maps channel overlap and client roaming behavior.
  2. Inspect per-client airtime use PHY rate and throughput fairness.
  3. Inspect surveyed RSSI SNR channel use and roaming measurements at user positions.
  4. Compare RSSI noise floor SNR and retransmissions per affected client.

Explanation

Correct Answer

B:

For Research Hub, the decisive mechanism is Airtime fairness. Wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity. Inspect per-client airtime use PHY rate and throughput fairness 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 Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

C:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

D:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

Question 975

At Technology Center, two campus blocks disagree on MST region name and revision despite the same VLAN plan. What should the engineer implement first to correct the stated condition?

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

Explanation

Correct Answer

B:

For Technology Center, 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 inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Technology Center 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

C:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Technology Center 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 active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center 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 976

At West Clinic, a sensitive campus fiber link requires link-layer encryption between two compatible switches. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect association RSN capability and failed security negotiation status.
  2. Inspect client TLS validation errors certificate SAN and trusted issuer store.
  3. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  4. Inspect MKA association state secured-port counters and key identity.

Explanation

Correct Answer

D:

For West Clinic, the decisive mechanism is MACsec campus link. MACsec protects Ethernet traffic at Layer 2 across an eligible link. Inspect MKA association state secured-port counters and key identity is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the West Clinic case, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

B:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the West Clinic case, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

C:

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 West Clinic case, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

Question 977

At Athletics Complex, untagged frames cross an AP trunk into different VLANs at each end. What operational rule should remain in place for later changes?

  1. Document native VLAN consistently and keep sensitive VLANs tagged.
  2. Stage ACL changes with console rollback to avoid management lockout.
  3. Do not enable jumbo frames on one device without validating intermediate hops.
  4. Guard against arbitrary untrusted client VLAN tagging on shared ports.

Explanation

Correct Answer

A:

For Athletics Complex, the decisive mechanism is Native VLAN mismatch. A native VLAN defines forwarding for untagged frames on a VLAN-aware trunk. Document native VLAN consistently and keep sensitive VLANs tagged is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk

C:

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 Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk

D:

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 Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk

Question 978

At Research Hub, a classroom installer connects two switch access ports with one short patch cable. Which controlled configuration is most likely to restore the required service?

  1. Apply the appropriate permit/deny order and direction on the data-path interface.
  2. Enable appropriate loop protection and STP behavior on eligible access ports.
  3. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  4. Align MTU and encapsulation requirements across the complete supported forwarding path.

Explanation

Correct Answer

B:

Enable appropriate loop protection and STP behavior on eligible access ports establishes the needed configuration in the case rather than merely measuring a symptom.

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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is loop protection isolates unintended forwarding cycles at Layer 2

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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is loop protection isolates unintended forwarding cycles at Layer 2

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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is loop protection isolates unintended forwarding cycles at Layer 2

Question 979

At Convention Center, a remote branch SSID bridges into an access VLAN that lacks the intended local policy. What should be examined to confirm the actual failure mechanism?

  1. Trace client frame exit from AP and switch VLAN path to enforcement.
  2. Cross-check RSSI noise floor SNR and retransmissions per affected client.
  3. Examine surveyed RSSI SNR channel use and roaming measurements at user positions.
  4. Examine co-channel AP visibility airtime utilization and contention counters.

Explanation

Correct Answer

A:

For Convention Center, the decisive mechanism is AOS 10 bridge forwarding. Bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway. Trace client frame exit from AP and switch VLAN path to enforcement is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

C:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

D:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

Question 980

At South Science Wing, a team assumes every station will get simultaneous spatial streams merely because AP supports MU-MIMO. How should the engineer validate success against the stated requirement?

  1. Check coverage and capacity with representative real devices and occupancy.
  2. Observe lower airtime contention and stable throughput during concurrent client use.
  3. Measure actual multi-client throughput without asserting all clients can use MU-MIMO.
  4. Measure improved SNR and reduced retry rate without oversizing transmit power.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Measure actual multi-client throughput without asserting all clients can use MU-MIMO 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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the South Science Wing case, That test could pass while the actual user-facing requirement still fails.
