Question 660

At Transit Operations Center, a floor has acceptable coverage but Wi-Fi calls drop because channel noise rises during production. What observable outcome would prove this repair actually works?

  1. Demonstrate the user reaches only the assigned subnet and policy resources.
  2. Retune a controlled radio and verify improved SNR plus voice packet success.
  3. Prove permitted bidirectional application traffic reaches the endpoint.
  4. Replace the suspect physical component and verify error rates stabilize under traffic.

Explanation

Correct Answer

B:

For Transit Operations Center, the decisive mechanism is Low SNR wireless retries. Signal strength without a noise context cannot establish usable WLAN quality. Retune a controlled radio and verify improved SNR plus voice packet success 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 Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

C:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

D:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

Question 661

At Administration Block, wireless clients disconnect when a single tunnel gateway goes offline despite multiple gateways being deployed. Which observation most directly isolates the likely cause before any change?

  1. Inspect cluster membership firmware compatibility load and tunnel health per gateway.
  2. Inspect keepalive reachability and failure signals independently of ISL health.
  3. Inspect ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  4. Compare configured and operational gateway state and ARP entries on both VSX peers.

Explanation

Correct Answer

A:

For Administration Block, the decisive mechanism is AOS 10 gateway cluster. An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. Inspect cluster membership firmware compatibility load and tunnel health per gateway is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Administration Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Administration Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Administration Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

Question 662

At Medical Annex, users can reach campus internal prefixes but all external traffic fails after default gateway removal. Which test best differentiates real success from a merely healthy status light?

  1. Receive a correct lease from the remote DHCP server on a test client.
  2. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  3. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  4. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid.

Explanation

Correct Answer

D:

For Medical Annex, the decisive mechanism is Default route selection. Default route 0.0.0.0/0 applies when no more specific IPv4 route matches. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Medical Annex case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

Question 663

At New Teaching Block, a printer MAC moves rapidly between two closet switchports during a wiring fault. Which observation most directly isolates the likely cause before any change?

  1. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags.
  2. Inspect address-table moves STP states and physical neighbor paths.
  3. Inspect hit counters rule ordering and packet direction for a controlled flow.
  4. Inspect frame-size drop counters PMTU behavior and VLAN/tunnel overhead.

Explanation

Correct Answer

B:

For New Teaching Block, the decisive mechanism is MAC address flapping. Repeated MAC address moves often indicate a changing Layer 2 path or loop. Inspect address-table moves STP states and physical neighbor paths is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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, Those observations could be normal while the stated fault persists. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

D:

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, Those observations could be normal while the stated fault persists. The specific mechanism is repeated MAC address moves often indicate a changing Layer 2 path or loop

Question 664

At Administration Block, two AOS-CX switches connect physically but never form OSPF adjacency because area IDs differ. What observable outcome would prove this repair actually works?

  1. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  2. Verify Full adjacency and appropriate route propagation for a test network.
  3. Confirm 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

B:

For Administration Block, the decisive mechanism is OSPF area membership. OSPF neighbors on a link must agree on essential area and protocol parameters. Verify Full adjacency and appropriate route propagation for a test network supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

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 Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

Question 665

At Convention Center, two distribution VSX peers use inconsistent virtual gateway MAC/IP for a staff VLAN. What should the engineer implement first to correct the stated condition?

  1. Enable supported loop protection on suitable edge ports and keep STP defenses active.
  2. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  3. Configure matching active-gateway address and MAC settings on the applicable VSX SVIs.
  4. Configure supported VRRP virtual gateway ownership and priority on matched interfaces.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is VSX active gateway. VSX active gateway allows distributed L3 gateway forwarding when configured consistently. Configure matching active-gateway address and MAC settings on the applicable VSX SVIs establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX active gateway allows distributed L3 gateway forwarding when configured consistently

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX active gateway allows distributed L3 gateway forwarding when configured consistently

D:

This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX active gateway allows distributed L3 gateway forwarding when configured consistently

Question 666

At Arts Pavilion, two distribution gateways both try to become master after an inconsistent VRRP priority update. Which test best differentiates real success from a merely healthy status light?

  1. Demonstrate Internet-bound test flows use the intended route while campus-specific routes remain valid.
  2. Demonstrate Full adjacency and appropriate route propagation for a test network.
  3. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  4. Check stable adjacency and intended timeout behavior after a controlled link loss.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is First-hop gateway election. VRRP abstracts the default gateway across eligible routing devices. Fail one gateway and confirm uninterrupted client default-route access within design targets supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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 Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

B:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. 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 Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

Question 667

At Riverside Building, two cables connect an access stack to aggregation but only one LACP member forwards. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Configure compatible LACP membership and logical LAG settings across the supported endpoints.
  2. Verify subscription device identity Central assignment and management reachability in the authorized tenant.
  3. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  4. Prevent independent links from creating a Layer 2 loop during LAG migrations.

Explanation

Correct Answers

A:

This is the implementation element for the Riverside Building case: LACP forms one logical bundle only when peers agree on aggregation parameters. The specific action Configure compatible LACP membership and logical LAG settings across the supported endpoints addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Riverside Building. Prevent independent links from creating a Layer 2 loop during LAG migrations 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 Central device onboarding: Cloud inventory association and device management connectivity are separate onboarding requirements. It does not resolve the LACP uplink provisioning requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is lACP forms one logical bundle only when peers agree on aggregation parameters

C:

This may be an ongoing precaution for Management VRF reachability: AOS-CX management VRF and default forwarding VRF may have separate reachability. It does not resolve the LACP uplink provisioning requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is lACP forms one logical bundle only when peers agree on aggregation parameters

Question 668

At East Student Center, a lab port meant for one kiosk accumulates MAC addresses from an unauthorized hub. What should be examined to confirm the actual failure mechanism?

  1. Inspect learned MAC count per interface and security-violation counters.
  2. Inspect untagged packet capture and both peers native VLAN configuration.
  3. Compare allowed VLAN list tagging and egress counters at both ends.
  4. Inspect interface VLAN mode learned MAC address and DHCP lease subnet.

Explanation

Correct Answer

A:

For East Student Center, the decisive mechanism is Port MAC limits. MAC address limits restrict excessive downstream identities on a switchport. Inspect learned MAC count per interface and security-violation counters is the most direct way to isolate this particular failure before making a change.

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 East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

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 East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

D:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

Question 669

At Transit Operations Center, a managed workstation receives Access-Reject despite a valid password after certificate renewal. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Review the specific ClearPass service match authentication source and TLS decision.
  2. Keep a source-controlled VLAN matrix for AP groups and switch closets.
  3. Trace the forward and reverse forwarding path including route recursion and ACLs.
  4. Do not broaden all enforcement results when one service policy is wrong.

Explanation

Correct Answers

A:

This is the implementation element for the Transit Operations Center case: An explicit RADIUS reject can come from credential validation or authorization policy. The specific action Review the specific ClearPass service match authentication source and TLS decision addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Transit Operations Center. Do not broaden all enforcement results when one service policy is wrong prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

B:

This may be an ongoing precaution for Wrong VLAN mapping: WLAN-to-wired mapping errors can appear as a DHCP or authorization defect. It does not resolve the RADIUS Access-Reject root cause requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is an explicit RADIUS reject can come from credential validation or authorization policy

C:

This may be a configuration step for Routed blackhole: Route presence alone does not prove usable bidirectional forwarding. It does not resolve the RADIUS Access-Reject root cause requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is an explicit RADIUS reject can come from credential validation or authorization policy

Question 670

At Engineering Tower, iP phones boot in the data VLAN because the switch no longer advertises LLDP-MED voice policy. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Never expand a trunk to all VLANs merely to resolve one missing segment.
  2. Set the switchport as an access member of the correct VLAN with matching policy.
  3. Guard against arbitrary untrusted client VLAN tagging on shared ports.
  4. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.

Explanation

Correct Answers

C:

This is the continuing risk-control element for Engineering Tower. Guard against arbitrary untrusted client VLAN tagging on shared ports 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 Engineering Tower case: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. The specific action Advertise approved LLDP-MED voice VLAN and separate PC data access classification addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for Tagged trunk allowlist: A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. It does not resolve the Voice VLAN LLDP-MED requirement in Engineering Tower and is not one of the two controls requested. The direct mechanism here is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

B:

This may be a configuration step for Access VLAN classification: An access port carries untagged frames in one configured access VLAN. It does not resolve the Voice VLAN LLDP-MED requirement in Engineering Tower and is not one of the two controls requested. The direct mechanism here is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies
