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

Question 361

At Athletics Complex, a fiber uplink remains operational but CRC errors spike after an optic replacement. Which postchange observation is the strongest evidence of correct operation?

  1. Verify the user reaches only the assigned subnet and policy resources.
  2. Prove permitted bidirectional application traffic reaches the endpoint.
  3. Simulate uplink failure and verify expected rapid convergence without loops.
  4. Replace the suspect physical component and verify error rates stabilize under traffic.

Explanation

Correct Answer

D:

For Athletics Complex, the decisive mechanism is Physical-link errors. Layer 1/2 corruption can degrade packets even though link status remains up. Replace the suspect physical component and verify error rates stabilize under traffic supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Athletics Complex case, That test could pass while the actual user-facing requirement still fails. 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 Athletics Complex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

Question 362

At Garden Hall, a branch switch receives RADIUS accept but cannot apply the returned downloaded user role. What operational rule should remain in place for later changes?

  1. Version role changes and retain a safe fallback if role retrieval fails.
  2. Monitor expiration windows and keep controlled rollback trust transitions.
  3. Protect log integrity retention and access according to data policy.
  4. Audit implicit permits and policy defaults after group membership changes.

Explanation

Correct Answer

A:

For Garden Hall, the decisive mechanism is Downloadable user roles. Downloadable roles coordinate centrally defined access controls with capable switch enforcement. Version role changes and retain a safe fallback if role retrieval fails is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. 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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

D:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

Question 363

At Technology Center, two campus blocks disagree on MST region name and revision despite the same VLAN plan. What operational rule should remain in place for later changes?

  1. Protect ISL paths and preserve independent keepalive failure domains.
  2. Require change review on VLAN-instance changes that alter MST boundaries.
  3. Validate shared virtual gateway settings on both peers before activating a new VLAN.
  4. Keep keepalive routing isolated from routine campus policy edits.

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. Require change review on VLAN-instance changes that alter MST boundaries is an enduring limitation on the operational risk, not simply a one-time passing test.

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

C:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

D:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

Question 364

At North Residence, a switch configuration gives excessive priority to noncritical traffic and starves normal services. Which configuration change best fits the network requirement and observed behavior?

  1. Evaluate supported multicast conversion and membership control for the audience size.
  2. Adjust transmit power with channel plan and measured minimum edge SNR.
  3. Apply supported egress queue scheduling with bounded high-priority service treatment.
  4. Tune supported band steering with proper 5-GHz coverage and compatibility checks.

Explanation

Correct Answer

C:

For North Residence, the decisive mechanism is Strict priority queue use. Priority scheduling affects service latency but requires careful queue sizing. Use supported egress queue scheduling with bounded high-priority service treatment establishes the needed configuration in the case rather than merely measuring a symptom.

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 North Residence case, Changing that neighboring feature does not implement the missing function. 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 North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

Question 365

At Athletics Complex, a user role updates correctly but accounting stop events are absent from the collector. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Provide valid server certificate and appropriate client trust configuration for EAP-TLS.
  2. Set up supported RADIUS accounting and consistent session identifier delivery.
  3. Choose supported WPA3-Enterprise settings and validated client capability before rollout.
  4. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.

Explanation

Correct Answer

B:

For Athletics Complex, the decisive mechanism is RADIUS accounting traceability. Authentication and accounting provide different information and require separate configuration. Configure supported RADIUS accounting and consistent session identifier delivery establishes the needed configuration in the case rather than merely measuring a symptom.

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is authentication and accounting provide different information and require separate configuration

C:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is authentication and accounting provide different information and require separate configuration

D:

The specific mechanism is authentication and accounting provide different information and require separate configuration

Question 366

At West Clinic, guest clients associate yet DHCP discover packets never reach a routed helper. Which investigation most directly explains why the intended service is not working?

  1. Examine authorized port VLAN DHCP DISCOVER/OFFER and relay counters.
  2. Examine routing table next-hop ARP and return-path filters hop by hop.
  3. Examine topology-change events root path role and transition timing.
  4. Examine client effective VLAN AP forward mode tagged frames and DHCP lease.

Explanation

Correct Answer

Question 368

At Innovation Studio, a security analyst needs both ingress and egress frames on a switch uplink to isolate packet loss. What observable outcome would prove this repair actually works?

  1. Read a test resource safely and confirm returned properties match the chosen selector.
  2. Capture identifiable test traffic without dropping ordinary production forwarding.
  3. Repeat representative traffic and demonstrate counters stay within accepted thresholds.
  4. Demonstrate a controlled internal failure affects only the intended sensor test.

Explanation

Correct Answer

B:

For Innovation Studio, the decisive mechanism is Port mirroring PCAP. Port mirroring copies selected frames for observation but is not a live forwarding path. Capture identifiable test traffic without dropping ordinary production forwarding supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to REST API selector use, where rEST representation selection and HTTP method choice affect what configuration is retrieved or changed In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is port mirroring copies selected frames for observation but is not a live forwarding path

C:

  1. Set up compatible LACP membership and logical LAG settings across the supported endpoints.
  2. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster.
  3. Establish the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  4. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.

Explanation

Correct Answer

D:

For Administration Block, the decisive mechanism is Central device onboarding. Cloud inventory association and device management connectivity are separate onboarding requirements. Verify subscription device identity Central assignment and management reachability in the authorized tenant establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

B:

This is relevant to Bridge versus tunneled WLAN traffic, where bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

C:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

Question 370

At Garden Hall, an AOS-CX distribution switch has a static default route pointing at an unreachable next hop. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Keep route rollback and reachability checks before gateway migrations.
  2. Enable matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  3. Review helper addresses and routes together during subnet migrations.
  4. Install a valid static route with a resolvable next hop and appropriate administrative distance.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Garden Hall. Keep route rollback and reachability checks before gateway migrations 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 Garden Hall case: A static route only forwards as intended when its next hop can be resolved. The specific action Install a valid static route with a resolvable next hop and appropriate administrative distance addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

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 Static route next hop requirement in Garden Hall and is not one of the two controls requested. The direct mechanism here is a static route only forwards as intended when its next hop can be resolved

C:

This may be an ongoing precaution for DHCP relay return routing: DHCP relay requires a valid return path to the relay address and client network. It does not resolve the Static route next hop requirement in Garden Hall and is not one of the two controls requested. The direct mechanism here is a static route only forwards as intended when its next hop can be resolved
