Question 930

At Bayside Campus, an auditorium has multi-antenna APs but most clients are single-stream devices. Which controlled acceptance test demonstrates the required behavior?

  1. Confirm coverage and capacity with representative real devices and occupancy.
  2. Measure actual multi-client throughput without asserting all clients can use MU-MIMO.
  3. Observe lower airtime contention and stable throughput during concurrent client use.
  4. Measure improved SNR and reduced retry rate without oversizing transmit power.

Explanation

Correct Answer

B:

For Bayside Campus, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Measure actual multi-client throughput without asserting all clients can use MU-MIMO 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 Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 931

At Administration Block, wireless clients disconnect when a single tunnel gateway goes offline despite multiple gateways being deployed. What measured or witnessed result should be required before signoff?

  1. Simulate controlled ISL loss and verify the documented split-brain prevention behavior.
  2. Confirm a client retains default-gateway reachability across a member failure.
  3. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists.
  4. Fail one gateway in a pilot and verify tunneled clients reconnect through eligible members.

Explanation

Correct Answer

D:

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. Fail one gateway in a pilot and verify tunneled clients reconnect through eligible members supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

B:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Administration Block case, That test could pass while the actual user-facing requirement still fails. 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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

Question 932

At Riverside Building, a student sets up a personal hotspot DHCP server connected to the campus access switch. What should be examined to confirm the actual failure mechanism?

  1. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags.
  2. Inspect dropped server replies from untrusted ports and the binding table.
  3. Inspect interface VLAN mode learned MAC address and DHCP lease subnet.
  4. Compare allowed VLAN list tagging and egress counters at both ends.

Explanation

Correct Answer

B:

For Riverside Building, the decisive mechanism is DHCP snooping trust boundary. DHCP snooping prevents DHCP-server responses from untrusted ports. Inspect dropped server replies from untrusted ports and the binding table 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 Riverside Building case, Those observations could be normal while the stated fault persists. 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, Those observations could be normal while the stated fault persists. 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 Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is dHCP snooping prevents DHCP-server responses from untrusted ports

Question 933

At North Residence, an outage makes ClearPass unavailable and a hospital phone cannot reach the emergency calling service. Which practical change is best suited to this topology and its constraints?

  1. Use supported administrative AAA command roles and TACACS+ where appropriate.
  2. Define a supported critical-role or fallback profile with minimum necessary services.
  3. Enable supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  4. Tune supported reauthentication and EAP timers based on measured client/server behavior.

Explanation

Correct Answer

B:

For North Residence, the decisive mechanism is Critical authentication fallback. Critical authorization controls how a port behaves if authentication service cannot be reached. Define a supported critical-role or fallback profile with minimum necessary services establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

C:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

D:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

Question 934

At Administration Block, a newly enabled MACsec interface remains down after link keys or peer policy differ. What should be examined to confirm the actual failure mechanism?

  1. Examine MKA association state secured-port counters and key identity.
  2. Examine client TLS validation errors certificate SAN and trusted issuer store.
  3. Examine TLS handshake certificate issuer expiry and ClearPass authentication log.
  4. Examine association RSN capability and failed security negotiation status.

Explanation

Correct Answer

A:

For Administration Block, the decisive mechanism is MACsec campus link. MACsec protects Ethernet traffic at Layer 2 across an eligible link. Inspect MKA association state secured-port counters and key identity is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

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, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

D:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Administration Block case, Those observations could be normal while the stated fault persists. The specific mechanism is mACsec protects Ethernet traffic at Layer 2 across an eligible link

Question 935

At Convention Center, a remote branch SSID bridges into an access VLAN that lacks the intended local policy. How should the engineer validate success against the stated requirement?

  1. Demonstrate a test client lands on the approved local VLAN and follows policy.
  2. Measure improved SNR and reduced retry rate without oversizing transmit power.
  3. Observe lower airtime contention and stable throughput during concurrent client use.
  4. Check coverage and capacity with representative real devices and occupancy.

Explanation

Correct Answer

A:

For Convention Center, the decisive mechanism is AOS 10 bridge forwarding. Bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway. Verify a test client lands on the approved local VLAN and follows policy supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

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

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

D:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bridge-mode SSID traffic exits at the local AP wired uplink rather than a tunnel gateway

Question 936

At Administration Block, a point-to-point routed fiber link has different OSPF network types at each endpoint. Which practical change is best suited to this topology and its constraints?

  1. Choose compatible supported OSPF network type for the link topology.
  2. Apply supported ECMP and account for session hash distribution across eligible paths.
  3. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  4. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.

Explanation

Correct Answer

A:

For Administration Block, the decisive mechanism is OSPF network type. OSPF network type affects hello behavior and DR election on multiaccess segments. Choose compatible supported OSPF network type for the link topology establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF network type affects hello behavior and DR election on multiaccess segments

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF network type affects hello behavior and DR election on multiaccess segments

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF network type affects hello behavior and DR election on multiaccess segments

Question 937

At Medical Annex, an access switch reports increasing discards on only one congested uplink. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.
  2. Collect interface error discard and utilization counters with suitable baseline intervals.
  3. Secure sensitive mirrored payloads and remove temporary sessions after testing.
  4. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.

Explanation

Correct Answers

B:

This is the implementation element for the Medical Annex case: Interface counters help distinguish physical corruption from congestion drops. The specific action Collect interface error discard and utilization counters with suitable baseline intervals addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Medical Annex. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals 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 NAE monitor rule: NAE agents monitor local switch state and can correlate rule conditions over time. It does not resolve the Switch telemetry counters requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is interface counters help distinguish physical corruption from congestion drops

C:

This may be an ongoing precaution for Port mirroring PCAP: Port mirroring copies selected frames for observation but is not a live forwarding path. It does not resolve the Switch telemetry counters requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is interface counters help distinguish physical corruption from congestion drops

Question 938

At Administration Block, the NOC cannot tell whether an outage affects SaaS or only on-campus DNS names. Which configuration change best fits the network requirement and observed behavior?
