Question 760

At Administration Block, a newly enabled MACsec interface remains down after link keys or peer policy differ. How should the engineer validate success against the stated requirement?

  1. Validate enterprise clients join securely with accepted ciphers and certificates.
  2. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  3. Check clients securely verify the intended RADIUS server before joining.
  4. Check authorized traffic passes with MACsec active and plaintext frames are rejected by policy.

Explanation

Correct Answer

D:

For Administration Block, the decisive mechanism is MACsec campus link. MACsec protects Ethernet traffic at Layer 2 across an eligible link. Confirm authorized traffic passes with MACsec active and plaintext frames are rejected by policy supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

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 Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

C:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

Question 761

At Administration Block, the NOC cannot tell whether an outage affects SaaS or only on-campus DNS names. Which postchange observation is the strongest evidence of correct operation?

  1. Demonstrate a controlled internal failure affects only the intended sensor test.
  2. Capture identifiable test traffic without dropping ordinary production forwarding.
  3. Generate a safe known event in the intended group and confirm delivery to the NOC.
  4. Trigger a safe lab threshold and verify historical record and alert generation.

Explanation

Correct Answer

A:

For Administration Block, the decisive mechanism is UXI internal and external tests. Internal and external synthetic tests isolate distinct service paths and failure domains. Verify a controlled internal failure affects only the intended sensor test supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

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 internal and external synthetic tests isolate distinct service paths and failure domains

C:

This is relevant to Central alert scope, where a management alert must be scoped to the correct managed devices and policy In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is internal and external synthetic tests isolate distinct service paths and failure domains

D:

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 internal and external synthetic tests isolate distinct service paths and failure domains

Question 762

At Athletics Complex, an AOS-CX switch exposes its HTTPS admin portal on user-access networks. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Restrict management-plane reachability and privileges to authorized VRFs roles and hosts.
  2. Establish trusted EAP-TLS client certificate chain identity policy and validity checks in ClearPass.
  3. Choose supported WPA3-Enterprise settings and validated client capability before rollout.
  4. Provide valid server certificate and appropriate client trust configuration for EAP-TLS.

Explanation

Correct Answer

A:

For Athletics Complex, the decisive mechanism is Management plane protection. Data-plane forwarding policy does not automatically secure device management services. Restrict management-plane reachability and privileges to authorized VRFs roles and hosts establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

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 Athletics Complex case, Changing that neighboring feature does not implement the missing function. 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 Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is data-plane forwarding policy does not automatically secure device management services

D:

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 data-plane forwarding policy does not automatically secure device management services

Question 763

At West Auditorium, two departments share access switches but must not initiate unauthorized lateral traffic. What should be examined to confirm the actual failure mechanism?

  1. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Inspect client TLS validation errors certificate SAN and trusted issuer store.
  3. Inspect association RSN capability and failed security negotiation status.
  4. Inspect effective roles group policy and same-VLAN as well as routed flows.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is Campus microsegmentation. Role-based segmentation can limit lateral flows beyond simple VLAN separation. Inspect effective roles group policy and same-VLAN as well as routed flows 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 West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is role-based segmentation can limit lateral flows beyond simple VLAN separation

B:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is role-based segmentation can limit lateral flows beyond simple VLAN separation

C:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is role-based segmentation can limit lateral flows beyond simple VLAN separation

Question 764

At New Teaching Block, an IoT device starts offering leases that override the authorized corporate DHCP scope. What should the engineer implement first to correct the stated condition?

  1. Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs.
  2. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  3. Establish the switchport as an access member of the correct VLAN with matching policy.
  4. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.

Explanation

Correct Answer

A:

For New Teaching Block, the decisive mechanism is DHCP snooping trust boundary. DHCP snooping prevents DHCP-server responses from untrusted ports. Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

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 dHCP snooping prevents DHCP-server responses from untrusted ports

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the New Teaching Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is dHCP snooping prevents DHCP-server responses from untrusted ports

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 New Teaching Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is dHCP snooping prevents DHCP-server responses from untrusted ports

Question 765

At Transit Operations Center, an existing gateway SVI has the wrong prefix and staff clients cannot reach routed services. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Avoid duplicate gateway addresses and record route/policy ownership.
  2. Create the correct VLAN SVI with verified IP prefix and forwarding policy.
  3. Establish the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  4. Assess roaming and segmentation impacts before changing WLAN forwarding mode.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Transit Operations Center. Avoid duplicate gateway addresses and record route/policy ownership 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 Transit Operations Center case: An SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch. The specific action Create the correct VLAN SVI with verified IP prefix and forwarding policy addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

C:

This may be a configuration step for AP uplink physical mapping: AP service onboarding depends on both physical power and the upstream management network. It does not resolve the SVI gateway provisioning requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is an SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch

D:

This may be an ongoing precaution for Bridge versus tunneled WLAN traffic: Bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy. It does not resolve the SVI gateway provisioning requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is an SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch

Question 766

At Riverside Building, a student sets up a personal hotspot DHCP server connected to the campus access switch. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs.
  2. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  3. Set the switchport as an access member of the correct VLAN with matching policy.
  4. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.

Explanation

Correct Answer

A:

For Riverside Building, the decisive mechanism is DHCP snooping trust boundary. DHCP snooping prevents DHCP-server responses from untrusted ports. Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is dHCP snooping prevents DHCP-server responses from untrusted ports

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is dHCP snooping prevents DHCP-server responses from untrusted ports

D:

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 Riverside Building case, Changing that neighboring feature does not implement the missing function.

Question 767

At Bayside Campus, a small IoT controller grows a learned MAC table after a wiring topology change. Which observation most directly isolates the likely cause before any change?

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

Explanation

Correct Answer

B:

For Bayside Campus, 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

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, 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 Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Bayside Campus 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 Bayside Campus 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 768

At Riverside Building, an access template accidentally treats RADIUS reject like a server timeout. Which test best differentiates real success from a merely healthy status light?

  1. Preserve authenticated sessions through the expected timer cycle in a controlled test.
  2. Block the primary in a lab and verify configured fallback behavior.
  3. Demonstrate rejected identities cannot reach internal resources while approved identities succeed.
  4. Connect a managed laptop and verify authorized access only after authentication.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is Unauthorized fail-open behavior. Authentication rejection is not the same as RADIUS server unavailability. Verify rejected identities cannot reach internal resources while approved identities succeed supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

B:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

D:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

Question 769

At Riverside Building, a sensor WLAN carries many short uplink messages and needs efficient 802.11ax resource sharing. What measured or witnessed result should be required before signoff?

  1. Check coverage and capacity with representative real devices and occupancy.
  2. Observe lower airtime contention and stable throughput during concurrent client use.
  3. Benchmark aggregate latency and throughput with realistic concurrent 802.11ax clients.
  4. Measure improved SNR and reduced retry rate without oversizing transmit power.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is OFDMA efficiency. OFDMA divides channel resources among eligible simultaneous users. Benchmark aggregate latency and throughput with realistic concurrent 802.11ax clients supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

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 Riverside Building case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

Question 770

At Transit Operations Center, an AOS-CX template pushes the same management gateway to two differently addressed branches. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Compare effective rendered variables and template configuration with branch inventory data.
  2. Inspect AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  3. Inspect LACP actor partner keys synchronization and individual member states.
  4. Trace where client frames exit the AP versus enter the Aruba gateway datapath.

Explanation

Correct Answer

A:

For Transit Operations Center, the decisive mechanism is Switch template variables. Template-based provisioning must resolve per-device parameters before switch configuration. Compare effective rendered variables and template configuration with branch inventory data is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is template-based provisioning must resolve per-device parameters before switch configuration

C:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is template-based provisioning must resolve per-device parameters before switch configuration

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is template-based provisioning must resolve per-device parameters before switch configuration
