Question 1050

At Research Hub, a wired label printer has no 802.1X supplicant and remains blocked on an authenticated access port. Which check provides the most useful information for fixing this deployment?

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

Explanation

Correct Answer

B:

For Research Hub, 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 Research Hub 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 Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the Research Hub 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 TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Research Hub 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 1051

At Lakeside Classroom, a 6-GHz WLAN configuration is inconsistent with management-frame protection expectations. What should be examined to confirm the actual failure mechanism?

  1. Examine effective roles group policy and same-VLAN as well as routed flows.
  2. Examine RSN capability PMF requirement and association refusal codes.
  3. Examine certificate chain expiry dates CRL/OCSP reachability and client errors.
  4. Examine start interim and stop records mapped to the NAD and user.

Explanation

Correct Answer

B:

For Lakeside Classroom, the decisive mechanism is Protected management frames. Protected management frames reduce forgery of eligible robust management frames. Inspect RSN capability PMF requirement and association refusal codes is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is protected management frames reduce forgery of eligible robust management frames

C:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is protected management frames reduce forgery of eligible robust management frames

D:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is protected management frames reduce forgery of eligible robust management frames

Question 1052

At East Student Center, a mixed-generation WLAN has a few low-rate clients consuming most shared radio time. Which investigation most directly explains why the intended service is not working?

  1. Examine per-client airtime rates and queue latency rather than total byte count only.
  2. Examine client WMM capability TID mapping and AP access-category statistics.
  3. Examine queue mappings weights and actual dropped/served traffic.
  4. Examine input DSCP markings trust state and egress queue classification.

Explanation

Correct Answer

A:

For East Student Center, the decisive mechanism is Airtime fairness QoS. Wireless performance must account for airtime occupancy as a shared resource. Inspect per-client airtime rates and queue latency rather than total byte count only is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

C:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

D:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

Question 1053

At Learning Commons, a wired device is placed into the wrong role because RADIUS attributes differ from switch expectations. Which configuration change best fits the network requirement and observed behavior?

  1. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  2. Map the returned VLAN attributes to an existing permitted switch VLAN and routed scope.
  3. Return supported VLAN or role attributes that match network enforcement configuration.
  4. Apply supported administrative AAA command roles and TACACS+ where appropriate.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is ClearPass enforcement attributes. An Access-Accept alone does not guarantee the intended authorization role was applied. Return supported VLAN or role attributes that match network enforcement configuration establishes the needed configuration in the case rather than merely measuring a symptom.

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 Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

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 Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

D:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

Question 1054

At Athletics Complex, high-value server VLAN traffic crosses a slow closet because root placement changed. What operational rule should remain in place for later changes?

  1. Audit root priorities and use guard features on user-facing ports.
  2. Guard against arbitrary untrusted client VLAN tagging on shared ports.
  3. Do not enable jumbo frames on one device without validating intermediate hops.
  4. Stage ACL changes with console rollback to avoid management lockout.

Explanation

Correct Answer

A:

For Athletics Complex, the decisive mechanism is STP root optimization. Spanning Tree selects the root by bridge ID and derives loop-free port roles. Audit root priorities and use guard features on user-facing ports is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

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 spanning Tree selects the root by bridge ID and derives loop-free port roles

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 spanning Tree selects the root by bridge ID and derives loop-free port roles

D:

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 spanning Tree selects the root by bridge ID and derives loop-free port roles

Question 1055

At North Library, large application transfers fail after a 9k-MTU server uplink crosses a 1500-byte campus segment. What should be examined to confirm the actual failure mechanism?

  1. Inspect untagged packet capture and both peers native VLAN configuration.
  2. Inspect interface VLAN mode learned MAC address and DHCP lease subnet.
  3. Inspect frame-size drop counters PMTU behavior and VLAN/tunnel overhead.
  4. Compare allowed VLAN list tagging and egress counters at both ends.

Explanation

Correct Answer

C:

For North Library, the decisive mechanism is End-to-end MTU and frames. A path's effective MTU is limited by the smallest supported segment and encapsulation overhead. Inspect frame-size drop counters PMTU behavior and VLAN/tunnel overhead 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 North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is a path's effective MTU is limited by the smallest supported segment and encapsulation overhead

B:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is a path's effective MTU is limited by the smallest supported segment and encapsulation overhead

D:

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 North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is a path's effective MTU is limited by the smallest supported segment and encapsulation overhead

Question 1056

At Convention Center, a remote branch SSID bridges into an access VLAN that lacks the intended local policy. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Avoid assuming gateway traffic inspection on an SSID configured to bridge locally.
  2. Establish the correct AOS 10 bridge-mode VLAN mapping and deploy enforcement at the chosen edge.
  3. Track both RF signal and noise as part of acceptance tests.
  4. Perform an active site survey covering attenuation interference and realistic client density.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Convention Center. Avoid assuming gateway traffic inspection on an SSID configured to bridge locally 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 Convention Center case: Bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway. The specific action Set the correct AOS 10 bridge-mode VLAN mapping and deploy enforcement at the chosen edge addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

C:

This may be an ongoing precaution for RSSI and SNR differentiation: SNR accounts for interference floor; RSSI alone does not predict useful wireless throughput. It does not resolve the AOS 10 bridge forwarding requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

D:

This may be a configuration step for RF predictive versus active survey: Predictive RF planning does not replace measured real-world attenuation and utilization. It does not resolve the AOS 10 bridge forwarding requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

Question 1057

At Bayside Campus, two equal-cost campus routes exist but an engineer expects each packet to alternate links. What observable outcome would prove this repair actually works?

  1. Verify Full adjacency and appropriate route propagation for a test network.
  2. Generate many independent test flows and compare distribution without requiring per-packet balance.
  3. Confirm stable adjacency and intended timeout behavior after a controlled link loss.
  4. Verify adjacency and LSA exchange match the expected topology.

Explanation

Correct Answer

B:

For Bayside Campus, the decisive mechanism is ECMP next-hop selection. ECMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet. Generate many independent test flows and compare distribution without requiring per-packet balance supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

C:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

D:

This is relevant to OSPF network type, where oSPF network type affects hello behavior and DR election on multiaccess segments In the Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

Question 1058

At Arts Pavilion, a classroom lab floods multicast traffic and creates queue loss on the uplink. What safety boundary prevents the same campus failure in future deployments?

  1. Tune thresholds from observed baselines rather than applying unsafe blanket drops.
  2. Document native VLAN consistently and keep sensitive VLANs tagged.
  3. Never expand a trunk to all VLANs merely to resolve one missing segment.
  4. Deny unapproved client VLAN changes and review port moves before deployment.

Explanation

Correct Answer

A:

For Arts Pavilion, the decisive mechanism is Broadcast storm control. Storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops. Tune thresholds from observed baselines rather than applying unsafe blanket drops is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Arts Pavilion case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

C:

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 Arts Pavilion case, A precaution for another failure mode is not the enduring boundary needed here. 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 Arts Pavilion case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

Question 1059

At Athletics Complex, a user-facing SVI sends OSPF hellos onto a shared client VLAN. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Test preemption and split-brain behavior during a controlled pilot.
  2. Keep routed uplinks active and audit interfaces when applying passive defaults.
  3. Enable matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  4. Make the user-facing OSPF interface passive while continuing appropriate network advertisement.

Explanation

Correct Answers

B:

This is the continuing risk-control element for Athletics Complex. Keep routed uplinks active and audit interfaces when applying passive defaults 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 Athletics Complex case: Passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised. The specific action Make the user-facing OSPF interface passive while continuing appropriate network advertisement addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for First-hop gateway election: VRRP abstracts the default gateway across eligible routing devices. It does not resolve the Passive OSPF access VLAN requirement in Athletics Complex and is not one of the two controls requested. The direct mechanism here is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

C:

This may be a configuration step for IPv6 OSPFv3 adjacency: OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. It does not resolve the Passive OSPF access VLAN requirement in Athletics Complex and is not one of the two controls requested. The direct mechanism here is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

Question 1060

At Garden Hall, a branch switch receives RADIUS accept but cannot apply the returned downloaded user role. What should the engineer implement first to correct the stated condition?

  1. Enforce role or group-based segmentation at the supported switching/gateway point.
  2. Publish supported downloadable role definitions and validate switch role retrieval.
  3. Configure supported RADIUS accounting and consistent session identifier delivery.
  4. Coordinate valid certificate chain rotation and trust propagation before expiry.

Explanation

Correct Answer

B:

For Garden Hall, the decisive mechanism is Downloadable user roles. Downloadable roles coordinate centrally defined access controls with capable switch enforcement. Publish supported downloadable role definitions and validate switch role retrieval establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Garden Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Garden Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

D:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Garden Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement
