Question 330

At Engineering Tower, 5-GHz-capable clients remain on congested 2.4 GHz even where 5 GHz is strong. Which ongoing safeguard best limits the specific risk after rollout?

  1. Do not blindly trust endpoint priority markings on public access ports.
  2. Maintain consistent DSCP-to-WMM mapping end to end.
  3. Rate-limit or police untrusted high-priority markings.
  4. Allow documented compatibility cases instead of forcing a universal band cutoff.

Explanation

Correct Answer

D:

For Engineering Tower, the decisive mechanism is Band steering under load. Band steering can guide dual-band association but depends on real RF and client support. Allow documented compatibility cases instead of forcing a universal band cutoff is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Engineering Tower case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

B:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Engineering Tower case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

C:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Engineering Tower case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

Question 331

At Convention Center, a CX 6200 stack ring becomes a line when one stacking cable is unplugged. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  2. Build compatible VSF stack members and restore a supported resilient link topology.
  3. Test preemption and split-brain protection before changing gateway priority.
  4. Document stack member IDs and cabling before replacing or renumbering units.

Explanation

Correct Answers

B:

This is the implementation element for the Convention Center case: VSF combines compatible access switches into a unified stack control plane. The specific action Build compatible VSF stack members and restore a supported resilient link topology addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Convention Center. Document stack member IDs and cabling before replacing or renumbering units prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be a configuration step for AOS 10 gateway cluster: An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. It does not resolve the VSF member order requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is vSF combines compatible access switches into a unified stack control plane

C:

This may be an ongoing precaution for VRRP redundant gateway: VRRP supplies virtual first-hop gateway failover between eligible routing peers. It does not resolve the VSF member order requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is vSF combines compatible access switches into a unified stack control plane

Question 332

At New Teaching Block, a printer MAC moves rapidly between two closet switchports during a wiring fault. What should the engineer implement first to correct the stated condition?

  1. Apply the appropriate permit/deny order and direction on the data-path interface.
  2. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  3. Align MTU and encapsulation requirements across the complete supported forwarding path.
  4. Trace MAC move logs and verify the loop or miswired physical path before intervening.

Explanation

Correct Answer

D:

For New Teaching Block, the decisive mechanism is MAC address flapping. Repeated MAC address moves often indicate a changing Layer 2 path or loop. Trace MAC move logs and verify the loop or miswired physical path before intervening 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 New Teaching Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

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 New Teaching Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

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 New Teaching Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

Question 333

At Central Hall, aOS-CX access switches inherit the wrong group template after a site copy. What should the engineer implement first to correct the stated condition?

  1. Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  2. Configure compatible LACP membership and logical LAG settings across the supported endpoints.
  3. Bind the device to its approved group and review group-level settings and local overrides.
  4. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster.

Explanation

Correct Answer

C:

For Central Hall, the decisive mechanism is Central group assignment. Central groups govern configuration inheritance while sites mainly aid location and operations. Bind the device to its approved group and review group-level settings and local overrides establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

B:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

D:

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 Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

Question 334

At Central Hall, guest VLAN 260 broadcasts DHCP discover but the helper points to an unreachable server. What measured or witnessed result should be required before signoff?

  1. Check both intended members distribute traffic and single-member loss is tolerated.
  2. Obtain a correctly scoped lease with gateway and DNS while unauthorized servers are rejected.
  3. See the AP obtain correct management addressing and report online in Central.
  4. Capture a test client flow at its designated wired VLAN or gateway policy point.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is Campus DHCP relay. DHCP relay forwards client requests across routed boundaries; switching alone does not. Obtain a correctly scoped lease with gateway and DNS while unauthorized servers are rejected supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

D:

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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

Question 335

At North Library, a new lecture hall has adequate modeled RSSI but poor live throughput during full attendance. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Adjust mounting antenna orientation and power using active RF measurements.
  2. Perform an active site survey covering attenuation interference and realistic client density.
  3. Set up guest authentication flow and role transitions with appropriate enforcement.
  4. Apply supported clustered gateway configuration with capacity and software-version compatibility.

Explanation

Correct Answer

B:

For North Library, the decisive mechanism is RF predictive versus active survey. Predictive RF planning does not replace measured real-world attenuation and utilization. Perform an active site survey covering attenuation interference and realistic client density 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 North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

D:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

Question 336

At Convention Center, a VRRP first-hop gateway fails but client devices still ARP for the old active MAC. Which configuration change best fits the network requirement and observed behavior?

  1. Configure supported VRRP with consistent virtual IP and safe priority/failover behavior.
  2. Restore an authorized default next hop and deliberate route preferences.
  3. Align OSPF area ID and supported area type at both neighboring interfaces.
  4. Set compatible OSPF interface hello and dead intervals on both peers.

Explanation

Correct Answer

A:

For Convention Center, the decisive mechanism is First-hop gateway election. VRRP abstracts the default gateway across eligible routing devices. Configure supported VRRP with consistent virtual IP and safe priority/failover behavior establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

C:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

D:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

Question 337

At Lakeside Classroom, a phone-plus-PC port puts both devices into the voice segment after a new access template. Which controlled acceptance test demonstrates the required behavior?

  1. Check untagged test frames land in the same approved VLAN at both endpoints.
  2. Demonstrate the phone uses the voice VLAN while the PC remains in the data VLAN.
  3. See device traffic only in its assigned broadcast domain and expected address scope.
  4. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.

Explanation

Correct Answer

B:

For Lakeside Classroom, the decisive mechanism is Voice VLAN LLDP-MED. LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. Verify the phone uses the voice VLAN while the PC remains in the data VLAN supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

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 Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

Question 338

At Athletics Complex, an AOS-CX switch pings the Internet in default VRF but cannot reach its management NTP server. What safety boundary prevents the same campus failure in future deployments?

  1. Assess roaming and segmentation impacts before changing WLAN forwarding mode.
  2. Prevent independent links from creating a Layer 2 loop during LAG migrations.
  3. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  4. Treat AP port changes as staged network access changes rather than bypassing admission.

Explanation

Correct Answer

C:

For Athletics Complex, the decisive mechanism is Management VRF reachability. AOS-CX management VRF and default forwarding VRF may have separate reachability. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

B:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

D:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

Question 339

At Innovation Studio, an uplink loses half its bundle links and remains active, saturating the surviving interface. How should the engineer validate success against the stated requirement?

  1. Remove a member in test and verify failover or protection follows the accepted threshold.
  2. Fail one gateway in a pilot and verify tunneled clients reconnect through eligible members.
  3. Simulate controlled ISL loss and verify the documented split-brain prevention behavior.
  4. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists.

Explanation

Correct Answer

A:

For Innovation Studio, the decisive mechanism is LACP minimum links. LAG interface health can depend on the configured minimum number of active members. Remove a member in test and verify failover or protection follows the accepted threshold supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to AOS 10 gateway cluster, where an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

C:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

D:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

  2. Verify balanced eligible clients and improved user experience rather than forcing equal counts.
  3. Verify pre-auth restrictions then post-auth Internet-only reachability.
  4. Fail one member under a staged load and confirm expected client access.

Explanation

Correct Answer

B:

For West Auditorium, the decisive mechanism is ClientMatch balancing. ClientMatch can guide client association and roaming decisions based on RF and load. Verify balanced eligible clients and improved user experience rather than forcing equal counts 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 West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load
