Question 350

At South Science Wing, a WLAN voice service is mapped to background access category despite proper wired DSCP. Which test best differentiates real success from a merely healthy status light?

  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. Generate concurrent voice and bulk traffic and compare latency under load.
  4. Observe suitable dual-band clients prefer 5 GHz without breaking legacy endpoints.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is WMM access categories. 802.11e WMM prioritizes wireless contention via different access categories. Generate concurrent voice and bulk traffic and compare latency under load 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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

Question 351

At Lakeside Classroom, slow legacy devices occupy a disproportionate share of WLAN airtime. What targeted evidence should the network engineer collect first?

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

Explanation

Correct Answer

D:

For Lakeside Classroom, 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

A:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Lakeside Classroom 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

B:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Lakeside Classroom 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 WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Lakeside Classroom 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 352

At West Auditorium, two departments share access switches but must not initiate unauthorized lateral traffic. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Audit implicit permits and policy defaults after group membership changes.
  2. Enforce role or group-based segmentation at the supported switching/gateway point.
  3. Never direct users to blindly accept arbitrary authentication server certificates.
  4. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.

Explanation

Correct Answers

A:

This is the continuing risk-control element for West Auditorium. Audit implicit permits and policy defaults after group membership changes 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 West Auditorium case: Role-based segmentation can limit lateral flows beyond simple VLAN separation. The specific action Enforce role or group-based segmentation at the supported switching/gateway point addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

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 Campus microsegmentation requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is role-based segmentation can limit lateral flows beyond simple VLAN separation

D:

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 Campus microsegmentation requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is role-based segmentation can limit lateral flows beyond simple VLAN separation

Question 353

At Medical Annex, a video phone boots but its expansion module remains disabled after a closet switch upgrade. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine per-port tag membership and tagged packet captures at the failing VLAN boundary.
  2. Examine switch PoE allocation operational draw power-denial and AP boot-event evidence.
  3. Examine management frames for authentication association rejection status and security mismatch.
  4. Examine EAPOL start identity exchange RADIUS decision and authenticated port status.

Explanation

Correct Answer

B:

For Medical Annex, the decisive mechanism is PoE power negotiation. 802.3af at and bt power classes and the switch budget constrain device operation. Inspect switch PoE allocation operational draw power-denial and AP boot-event evidence is the most direct way to isolate this particular failure before making a change.

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 Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

C:

This is relevant to 802.11 association sequence, where 802.11 discovery and association occur before user traffic can be successfully forwarded In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

D:

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 Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.3af at and bt power classes and the switch budget constrain device operation

Question 354

At Bayside Campus, an auditorium has multi-antenna APs but most clients are single-stream devices. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect surveyed RSSI SNR channel use and roaming measurements at user positions.
  2. Inspect AP/client spatial-stream capability and radio utilization.
  3. Inspect co-channel AP visibility airtime utilization and contention counters.
  4. Compare RSSI noise floor SNR and retransmissions per affected client.

Explanation

Correct Answer

B:

For Bayside Campus, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Inspect AP/client spatial-stream capability and radio utilization is the most direct way to isolate this particular failure before making a change.

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 Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 355

At Main Data Center, a branch needs to advertise a subnet but must not accept OSPF neighbors from endpoints. Which postchange observation is the strongest evidence of correct operation?

  1. Check prefix advertisement with no user-port OSPF adjacency.
  2. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  3. Check appropriate IPv6 routes are learned and prefixes stay reachable.
  4. Generate many independent test flows and compare distribution without requiring per-packet balance.

Explanation

Correct Answer

A:

For Main Data Center, the decisive mechanism is Passive OSPF access VLAN. Passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised. Confirm prefix advertisement with no user-port OSPF adjacency supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. 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 Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is passive OSPF prevents hello-based adjacency on the interface while its connected prefix can be advertised

Question 356

At Main Data Center, an AP group uses overly broad management roles during contractor onboarding. What measured or witnessed result should be required before signoff?

  1. Check clients securely verify the intended RADIUS server before joining.
  2. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  3. Validate enterprise clients join securely with accepted ciphers and certificates.
  4. Check approved administrators connect while ordinary user subnets cannot.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is Management plane protection. Data-plane forwarding policy does not automatically secure device management services. Confirm approved administrators connect while ordinary user subnets cannot supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

B:

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 Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

C:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

Question 357

At North Residence, an inter-VLAN DHCP relay forwards requests yet the server has no route back to relay GIADDR. Which change-management constraint best guards against recurrence?

  1. Retain route rollback and reachability checks before gateway migrations.
  2. Secure internal prefixes with appropriate specific routes and reject unwanted default announcements.
  3. Review area settings as paired changes and preserve routing rollback.
  4. Review helper addresses and routes together during subnet migrations.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is DHCP relay return routing. DHCP relay requires a valid return path to the relay address and client network. Review helper addresses and routes together during subnet migrations is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dHCP relay requires a valid return path to the relay address and client network

B:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dHCP relay requires a valid return path to the relay address and client network

C:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dHCP relay requires a valid return path to the relay address and client network

Question 358

At East Student Center, an AP has Internet management but no functional user-tunnel path to the gateways. What measured or witnessed result should be required before signoff?

  1. Measure improved SNR and reduced retry rate without oversizing transmit power.
  2. Check coverage and capacity with representative real devices and occupancy.
  3. Observe lower airtime contention and stable throughput during concurrent client use.
  4. Test authorized traffic through the designated gateway while a disallowed flow is blocked.

Explanation

Correct Answer

D:

For East Student Center, the decisive mechanism is AOS 10 tunnel forwarding. Tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN. Test authorized traffic through the designated gateway while a disallowed flow is blocked supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN

B:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN

Question 359

At Convention Center, a BYOD device presents an untrusted issuing CA in enterprise EAP-TLS onboarding. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Set up supported RADIUS accounting and consistent session identifier delivery.
  2. Enforce role or group-based segmentation at the supported switching/gateway point.
  3. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.
  4. Restrict management-plane reachability and privileges to authorized VRFs roles and hosts.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is EAP-TLS client certificate validation. EAP-TLS authenticates possession of the client certificate private key and validates trust. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

D:

This is relevant to Management plane protection, where data-plane forwarding policy does not automatically secure device management services In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

Question 360

At Main Data Center, an access switch shows increasing runts and drops while the user complains of unstable wired access. Which preventive control is most relevant to this scenario over time?

  1. Retain spare supported optics and baseline error counters before maintenance.
  2. Apply staged routing changes and monitor policy symmetry.
  3. Retain rollback access during global STP region or root changes.
  4. Retain a source-controlled VLAN matrix for AP groups and switch closets.

Explanation

Correct Answer

A:

For Main Data Center, the decisive mechanism is Physical-link errors. Layer 1/2 corruption can degrade packets even though link status remains up. Retain spare supported optics and baseline error counters before maintenance is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Main Data Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Main Data Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

D:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Main Data Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up
