Question 710

At Lakeside Classroom, corporate phones reject the wireless authentication server after its certificate renewal. What safety boundary prevents the same campus failure in future deployments?

  1. Apply least privilege and log management configuration changes.
  2. Audit implicit permits and policy defaults after group membership changes.
  3. Protect log integrity retention and access according to data policy.
  4. Never direct users to blindly accept arbitrary authentication server certificates.

Explanation

Correct Answer

D:

For Lakeside Classroom, the decisive mechanism is EAP-TLS RADIUS server certificate. Mutual TLS requires client-side confidence in the EAP server identity. Never direct users to blindly accept arbitrary authentication server certificates is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Management plane protection, where data-plane forwarding policy does not automatically secure device management services In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

Question 711

At Convention Center, a contractor authenticates correctly but receives an employee DHCP subnet. Which ongoing safeguard best limits the specific risk after rollout?

  1. Treat MAC addresses as spoofable identifiers and limit privileges.
  2. Validate access-switch VLAN availability before rolling out central enforcement changes.
  3. Do not broadly fail-open protected ports on temporary RADIUS loss.
  4. Version enforcement profiles and test against the deployed switch software.

Explanation

Correct Answer

B:

For Convention Center, the decisive mechanism is Dynamic VLAN on wired port. Dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support. Validate access-switch VLAN availability before rolling out central enforcement changes is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to MAB for headless IoT, where mAB is a weaker fallback identity mechanism than certificate-based 802.1X In the Convention Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

D:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Convention Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

Question 712

At Medical Annex, a camera segment should allow only media servers and DNS, yet a broad permit remains. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Examine match counters packet path and route bypass around the intended ACL.
  3. Examine client TLS validation errors certificate SAN and trusted issuer store.
  4. Examine association RSN capability and failed security negotiation status.

Explanation

Correct Answer

B:

For Medical Annex, the decisive mechanism is Access ACL segmentation. A policy object is effective only where attached to the forwarding path. Inspect match counters packet path and route bypass around the intended ACL is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is a policy object is effective only where attached to the forwarding path

C:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is a policy object is effective only where attached to the forwarding path

D:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is a policy object is effective only where attached to the forwarding path

Question 713

At Bayside Campus, a small IoT controller grows a learned MAC table after a wiring topology change. What should the engineer implement first to correct the stated condition?

  1. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  2. Synchronize native VLAN configuration and avoid using native VLAN for untrusted access where possible.
  3. Set up appropriate port MAC learn limits or access controls for the endpoint class.
  4. Establish the switchport as an access member of the correct VLAN with matching policy.

Explanation

Correct Answer

C:

For Bayside Campus, the decisive mechanism is Port MAC limits. MAC address limits restrict excessive downstream identities on a switchport. Configure appropriate port MAC learn limits or access controls for the endpoint class establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

B:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Bayside Campus case, Changing that neighboring feature does not implement the missing function. 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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

Question 714

At Administration Block, an API monitoring script requests config values but accidentally reads only interface status attributes. Which postchange observation is the strongest evidence of correct operation?

  1. Trigger a safe lab threshold and verify historical record and alert generation.
  2. Read a test resource safely and confirm returned properties match the chosen selector.
  3. Show controlled service degradation is detected and accurately localized by UXI.
  4. Capture identifiable test traffic without dropping ordinary production forwarding.

Explanation

Correct Answer

B:

For Administration Block, the decisive mechanism is REST API selector use. REST representation selection and HTTP method choice affect what configuration is retrieved or changed. Read a test resource safely and confirm returned properties match the chosen selector supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

C:

This is relevant to UXI client experience probes, where uXI sensors run synthetic end-user workflows to reveal service-layer failures In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

D:

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

Question 715

At Central Hall, a secured OSPF adjacency drops after one core switch changes its authentication key. Which postchange observation is the strongest evidence of correct operation?

  1. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  2. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  3. Confirm authorized peers reach Full while mismatched lab peers fail.
  4. Generate many independent test flows and compare distribution without requiring per-packet balance.

Explanation

Correct Answer

C:

For Central Hall, the decisive mechanism is OSPF neighbor authentication. OSPF authentication protects adjacency formation against unauthorized peers. Confirm authorized peers reach Full while mismatched lab peers fail 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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

B:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

Question 716

At Arts Pavilion, two distribution gateways both try to become master after an inconsistent VRRP priority update. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Review area settings as paired changes and preserve routing rollback.
  2. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.
  3. Test preemption and split-brain behavior during a controlled pilot.
  4. Restore an authorized default next hop and deliberate route preferences.

Explanation

Correct Answers

B:

This is the implementation element for the Arts Pavilion case: VRRP abstracts the default gateway across eligible routing devices. The specific action Configure supported VRRP with consistent virtual IP and safe priority/failover behavior addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Arts Pavilion. Test preemption and split-brain behavior during a controlled pilot prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be an ongoing precaution for OSPF area membership: OSPF neighbors on a link must agree on essential area and protocol parameters. It does not resolve the First-hop gateway election requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is VRRP abstracts the default gateway across eligible routing devices

D:

This may be a configuration step for Default route selection: Default route 0.0.0.0/0 applies when no more specific IPv4 route matches. It does not resolve the First-hop gateway election requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is VRRP abstracts the default gateway across eligible routing devices

Question 717

At North Library, an IDF trunk carries voice VLAN 310 but its upstream interface mistakenly permits only data VLAN 110. What measured or witnessed result should be required before signoff?

  1. Pass tagged test frames for the intended VLAN while proving unauthorized VLANs remain blocked.
  2. Run bidirectional throughput tests with no late collisions or increasing CRC errors.
  3. Sustain the full AP or phone feature load without PoE budget alarms or resets.
  4. Match the discovered neighbor port to the documented physical switch path.

Explanation

Correct Answer

A:

For North Library, the decisive mechanism is 802.1Q VLAN tagging. 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links. Pass tagged test frames for the intended VLAN while proving unauthorized VLANs remain blocked supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

C:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

D:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

Question 718

At East Student Center, a switch administrator can log in but unauthorized commands remain allowed through local fallback. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Configure appropriate RADIUS failover and tested timeout/retry settings.
  2. Enable supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  3. Return supported VLAN or role attributes that match network enforcement configuration.
  4. Use supported administrative AAA command roles and TACACS+ where appropriate.

Explanation

Correct Answer

D:

For East Student Center, the decisive mechanism is TACACS+ admin AAA distinction. Administrative command authorization and client-port 802.1X solve different AAA problems. Use supported administrative AAA command roles and TACACS+ where appropriate establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the East Student Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is administrative command authorization and client-port 802.1X solve different AAA problems

B:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the East Student Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is administrative command authorization and client-port 802.1X solve different AAA problems

C:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the East Student Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is administrative command authorization and client-port 802.1X solve different AAA problems

Question 719

At Garden Hall, a client sees strong -55 dBm RSSI yet low data rates beside an industrial interferer. How should the engineer validate success against the stated requirement?

  1. Fail one member under a staged load and confirm expected client access.
  2. Test authorized traffic through the designated gateway while a disallowed flow is blocked.
  3. Verify a test client lands on the approved local VLAN and follows policy.
  4. Measure improved SNR and reduced retry rate without oversizing transmit power.

Explanation

Correct Answer

D:

For Garden Hall, the decisive mechanism is RSSI and SNR differentiation. SNR accounts for interference floor; RSSI alone does not predict useful wireless throughput. Measure improved SNR and reduced retry rate without oversizing transmit power supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput

B:

This is relevant to AOS 10 tunnel forwarding, where tunnel forwarding places client data on the gateway datapath rather than a local bridged VLAN In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput

C:

This is relevant to AOS 10 bridge forwarding, where bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput

Question 720

At West Auditorium, an employee connects a small unmanaged switch that sends BPDUs into an edge access port. What measured or witnessed result should be required before signoff?

  1. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.
  2. Run controlled large-payload tests and confirm reliable path MTU behavior.
  3. Permit a specifically authorized app and block the matching forbidden traffic.
  4. Confirm a test BPDU causes edge protection without disabling authorized trunks.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is BPDU guard edge ports. BPDU guard protects edge ports from becoming transit paths for unauthorized switches. Confirm a test BPDU causes edge protection without disabling authorized trunks supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches

B:

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 West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches

C:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches
