Question 940

At North Residence, voIP phones mark DSCP EF but a distribution switch overwrites it to best effort. Which postchange observation is the strongest evidence of correct operation?

  1. Walk test improved roaming and reduced overlap at the target busy locations.
  2. Run the target application with representative subscribers and verify latency and load.
  3. Observe suitable dual-band clients prefer 5 GHz without breaking legacy endpoints.
  4. Verify authorized voice gets its intended queue while bulk traffic does not.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is DSCP trust boundary. QoS trust boundaries determine which received packet markings affect forwarding priority. Verify authorized voice gets its intended queue while bulk traffic does not supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

B:

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

C:

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

Question 941

At Athletics Complex, a user-facing SVI sends OSPF hellos onto a shared client VLAN. Which investigation most directly explains why the intended service is not working?

  1. Inspect VRRP advertisements gateway owner and virtual MAC state.
  2. Inspect IPv6 link-local neighbors OSPFv3 interface area and router ID.
  3. Inspect hello captures and neighbor table on the user SVI.
  4. Inspect active equal-cost routes flow hashing and actual per-link counters.

Explanation

Correct Answer

C:

For Athletics Complex, the decisive mechanism is Passive OSPF access VLAN. Passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised. Inspect hello captures and neighbor table on the user SVI is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

B:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

D:

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 Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

Question 942

At Hillcrest Campus, a building badge reader must be admitted with restricted access despite lacking EAP-TLS capability. What targeted evidence should the network engineer collect first?

  1. Examine EAP exchanges identity retries and reauthentication failure timestamps.
  2. Examine MAB attempt matched endpoint identity and ClearPass policy.
  3. Examine command authorization logs versus client-port authentication events.
  4. Examine RADIUS role attributes switch VLAN membership and DHCP address assignment.

Explanation

Correct Answer

B:

For Hillcrest Campus, the decisive mechanism is MAB for headless IoT. MAB is a weaker fallback identity mechanism than certificate-based 802.1X. Inspect MAB attempt matched endpoint identity and ClearPass policy is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

D:

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, Those observations could be normal while the stated fault persists. The specific mechanism is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

Question 943

At South Science Wing, a user logs in successfully but accounting stop records never reach ClearPass. Which postchange observation is the strongest evidence of correct operation?

  1. Block the primary in a lab and verify configured fallback behavior.
  2. Correlate test connect disconnect events to server accounting logs.
  3. Demonstrate the accepted identity receives the intended permissions and IP subnet.
  4. Connect a managed laptop and verify authorized access only after authentication.

Explanation

Correct Answer

B:

For South Science Wing, the decisive mechanism is RADIUS accounting for audit. AAA accounting tracks session use separately from authentication and authorization. Correlate test connect disconnect events to server accounting logs supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

C:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

D:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

Question 944

At Athletics Complex, an AOS-CX switch exposes its HTTPS admin portal on user-access networks. What should be examined to confirm the actual failure mechanism?

  1. Inspect client TLS validation errors certificate SAN and trusted issuer store.
  2. Inspect active management listeners ACL rules and access logs.
  3. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  4. Inspect association RSN capability and failed security negotiation status.

Explanation

Correct Answer

B:

For Athletics Complex, the decisive mechanism is Management plane protection. Data-plane forwarding policy does not automatically secure device management services. Inspect active management listeners ACL rules and access logs 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 Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

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 Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

D:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

Question 945

At Medical Annex, a hospital runs wide channels across many APs and has too few independent channels for reuse. What should the engineer implement first to correct the stated condition?

  1. Adjust mounting antenna orientation and power using active RF measurements.
  2. Select narrower supported channel width when needed for density and clean frequency reuse.
  3. Apply supported clustered gateway configuration with capacity and software-version compatibility.
  4. Set up guest authentication flow and role transitions with appropriate enforcement.

Explanation

Correct Answer

B:

For Medical Annex, the decisive mechanism is Channel width in density. Wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs. Select narrower supported channel width when needed for density and clean frequency reuse establishes the needed configuration in the case rather than merely measuring a symptom.

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 Medical Annex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

C:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Medical Annex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

D:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Medical Annex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

Question 946

At Main Data Center, a university deployed 80-MHz 5-GHz channels to maximize single-client rates but dense classrooms now collide. How should the engineer validate success against the stated requirement?

  1. Measure acceptable coverage plus SNR at walking and seated client locations.
  2. Fail one member under a staged load and confirm expected client access.
  3. Verify pre-auth restrictions then post-auth Internet-only reachability.
  4. Verify more concurrent clients meet latency goals after a measured channel-width pilot.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is Channel width in density. Wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs. Verify more concurrent clients meet latency goals after a measured channel-width pilot supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

Question 947

At Garden Hall, a voice phone learns unexpected switch-port information after an AP was moved between IDFs. Which observation most directly isolates the likely cause before any change?

  1. Examine management frames for authentication association rejection status and security mismatch.
  2. Examine EAPOL start identity exchange RADIUS decision and authenticated port status.
  3. Examine per-port tag membership and tagged packet captures at the failing VLAN boundary.
  4. Examine local and remote LLDP chassis port and management addresses against physical patch records.

Explanation

Correct Answer

D:

For Garden Hall, the decisive mechanism is LLDP topology and discovery. LLDP supplies adjacent-device identity without proving end-to-end routing or authentication. Inspect local and remote LLDP chassis port and management addresses against physical patch records is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to 802.11 association sequence, where 802.11 discovery and association occur before user traffic can be successfully forwarded In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP supplies adjacent-device identity without proving end-to-end routing or authentication

B:

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 Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP supplies adjacent-device identity without proving end-to-end routing or authentication

C:

This is relevant to 802.1Q VLAN tagging, where 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP supplies adjacent-device identity without proving end-to-end routing or authentication

Question 948

At Administration Block, an uplink forwards VLAN 120 but silently drops newly introduced VLAN 350. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  2. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  3. Never expand a trunk to all VLANs merely to resolve one missing segment.
  4. Do not enable jumbo frames on one device without validating intermediate hops.

Explanation

Correct Answers

A:

This is the implementation element for the Administration Block case: A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. The specific action Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Administration Block. Never expand a trunk to all VLANs merely to resolve one missing segment 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 Voice VLAN LLDP-MED: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. It does not resolve the Tagged trunk allowlist requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

D:

This may be an ongoing precaution for End-to-end MTU and frames: A path's effective MTU is limited by the smallest supported segment and encapsulation overhead. It does not resolve the Tagged trunk allowlist requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

Question 949

  1. Examine EAP exchanges identity retries and reauthentication failure timestamps.
  2. Examine RADIUS role attributes switch VLAN membership and DHCP address assignment.
  3. Examine command authorization logs versus client-port authentication events.
  4. Examine server status transport timeouts and alternate server selection.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is RADIUS authorization timeout. Authentication server reachability and retry order influence network-admission decisions. Inspect server status transport timeouts and alternate server selection is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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, Those observations could be normal while the stated fault persists. 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, Those observations could be normal while the stated fault persists. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is authentication server reachability and retry order influence network-admission decisions

Question 950

At Hillcrest Campus, a fiber handoff has link errors after mismatching optic wavelength and connector types. Which controlled configuration is most likely to restore the required service?

  1. Add an authorized management-VRF route and correct source reachability for the target service.
  2. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  3. Select supported transceivers fiber type wavelength and distance for both endpoints.
  4. Bind the device to its approved group and review group-level settings and local overrides.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Fiber optic transceiver fit. Optical compatibility relies on physical medium optics reach and platform support. Select supported transceivers fiber type wavelength and distance for both endpoints establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 optical compatibility relies on physical medium optics reach and platform support

B:

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 optical compatibility relies on physical medium optics reach and platform support

D:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Hillcrest Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is optical compatibility relies on physical medium optics reach and platform support
