Question 1180

At Convention Center, an access network changes authentication timeout settings but client EAP exchanges exceed them. Which check provides the most useful information for fixing this deployment?

  1. Examine server status transport timeouts and alternate server selection.
  2. Examine EAPOL handshake switch authentication state and RADIUS responses.
  3. Examine EAP exchanges identity retries and reauthentication failure timestamps.
  4. Examine Access-Accept AV pairs and effective port role or VLAN assignment.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is Supplicant reauthentication intervals. Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. Inspect EAP exchanges identity retries and reauthentication failure timestamps is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

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 Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

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, Those observations could be normal while the stated fault persists. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

Question 1181

At Central Hall, a meeting-room patch moves a switch uplink into a port configured for endpoint traffic. Which controlled acceptance test demonstrates the required behavior?

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

Explanation

Correct Answer

A:

For Central Hall, 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

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 Central Hall 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 End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the Central Hall 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

D:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Central Hall 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

Question 1182

At Transit Operations Center, a floor has acceptable coverage but Wi-Fi calls drop because channel noise rises during production. Which investigation most directly explains why the intended service is not working?

  1. Cross-check noise-floor spectral activity and per-client retry rates.
  2. Examine routing table next-hop ARP and return-path filters hop by hop.
  3. Examine client effective VLAN AP forward mode tagged frames and DHCP lease.
  4. Examine FCS CRC counters optical levels and negotiated mode.

Explanation

Correct Answer

A:

For Transit Operations Center, the decisive mechanism is Low SNR wireless retries. Signal strength without a noise context cannot establish usable WLAN quality. Compare noise-floor spectral activity and per-client retry rates is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

C:

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, Those observations could be normal while the stated fault persists. 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, Those observations could be normal while the stated fault persists. The specific mechanism is signal strength without a noise context cannot establish usable WLAN quality

Question 1183

At Bayside Campus, a small IoT controller grows a learned MAC table after a wiring topology change. What measured or witnessed result should be required before signoff?

  1. Connect an authorized endpoint and then an extra device to verify expected treatment.
  2. Check untagged test frames land in the same approved VLAN at both endpoints.
  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

A:

For Bayside Campus, the decisive mechanism is Port MAC limits. MAC address limits restrict excessive downstream identities on a switchport. Connect an authorized endpoint and then an extra device to verify expected treatment supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

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 Bayside Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

Question 1184

At Medical Annex, a routed user VLAN fails when the primary distribution gateway is restarted. What safety boundary prevents the same campus failure in future deployments?

  1. Keep keepalive routing isolated from routine campus policy edits.
  2. Test preemption and split-brain protection before changing gateway priority.
  3. Protect ISL paths and preserve independent keepalive failure domains.
  4. Validate shared virtual gateway settings on both peers before activating a new VLAN.

Explanation

Correct Answer

B:

For Medical Annex, the decisive mechanism is VRRP redundant gateway. VRRP supplies virtual first-hop gateway failover between eligible routing peers. Test preemption and split-brain protection before changing gateway priority is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

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 Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

Question 1185

At Medical Annex, incident logs from distribution switches disagree on time by several minutes. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Protect log retention and authenticated time synchronization.
  2. Align reliable NTP time and scoped syslog forwarding to the approved collector.
  3. Protect sensitive mirrored payloads and remove temporary sessions after testing.
  4. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Medical Annex. Protect log retention and authenticated time synchronization 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 Medical Annex case: System logging accuracy needs both transport and synchronized timestamps. The specific action Align reliable NTP time and scoped syslog forwarding to the approved collector addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

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 Syslog timestamps and forwarding requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is system logging accuracy needs both transport and synchronized timestamps

D:

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 Syslog timestamps and forwarding requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is system logging accuracy needs both transport and synchronized timestamps

Question 1186

At Learning Commons, a campus SSID has acceptable RF but slow 802.1X exchanges at every AP move. How should the engineer validate success against the stated requirement?

  1. Measure acceptable coverage plus SNR at walking and seated client locations.
  2. Measure lower roaming latency on supported handsets without blocking legacy clients.
  3. Check coverage and capacity with representative real devices and occupancy.
  4. Demonstrate pre-auth restrictions then post-auth Internet-only reachability.

Explanation

Correct Answer

B:

For Learning Commons, the decisive mechanism is 802.11r fast transition. 802.11r enables fast BSS transition to shorten supported reauthentication during roaming. Measure lower roaming latency on supported handsets without blocking legacy clients 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 Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

C:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

D:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11r enables fast BSS transition to shorten supported reauthentication during roaming

Question 1187

At New Teaching Block, a wiring closet double-homes a LAG and the peer switch uses a different aggregate key. What should be examined to confirm the actual failure mechanism?

  1. Examine configuration inheritance group membership and effective setting differences.
  2. Examine route table source interface and ACLs in the actual management VRF.
  3. Examine LACP actor partner keys synchronization and individual member states.
  4. Examine serial record device assignment onboarding logs DNS and outbound management connectivity.

Explanation

Correct Answer

C:

For New Teaching Block, the decisive mechanism is LACP uplink provisioning. LACP forms one logical bundle only when peers agree on aggregation parameters. Inspect LACP actor partner keys synchronization and individual member states is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

B:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

D:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

Question 1188

At Athletics Complex, a campus pair identifies two independent routing processes using an identical router ID. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Test preemption and split-brain behavior during a controlled pilot.
  2. Assign unique router IDs and refresh OSPF process state where needed.
  3. Include router IDs in switch provisioning validation.
  4. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.

Explanation

Correct Answers

B:

This is the implementation element for the Athletics Complex case: An OSPF router ID identifies a routing instance independently of VLAN labels. The specific action Assign unique router IDs and refresh OSPF process state where needed addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Athletics Complex. Include router IDs in switch provisioning validation 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 First-hop gateway election: VRRP abstracts the default gateway across eligible routing devices. It does not resolve the OSPF router ID uniqueness requirement in Athletics Complex and is not one of the two controls requested. The direct mechanism here is an OSPF router ID identifies a routing instance independently of VLAN labels

D:

This may be a configuration step for IPv6 OSPFv3 adjacency: OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. It does not resolve the OSPF router ID uniqueness requirement in Athletics Complex and is not one of the two controls requested. The direct mechanism here is an OSPF router ID identifies a routing instance independently of VLAN labels

Question 1189

At South Science Wing, a team assumes every station will get simultaneous spatial streams merely because AP supports MU-MIMO. What safety boundary prevents the same campus failure in future deployments?

  1. Track both RF signal and noise as part of acceptance tests.
  2. Retain mixed-client fairness and RF design rather than relying only on antenna count.
  3. Avoid excessive AP transmit power that creates broad overlapping cells.
  4. Repeat surveys after major layout or material changes rather than trusting only plans.

Explanation

Correct Answer

B:

For South Science Wing, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Retain mixed-client fairness and RF design rather than relying only on antenna count is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. 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 South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 1190

At Arts Pavilion, a critical voice queue experiences latency because every egress queue uses weighted round-robin. Which investigation most directly explains why the intended service is not working?

  1. Inspect group subscriptions multicast airtime and converted frame counts.
  2. Inspect queue mappings weights and actual dropped/served traffic.
  3. Inspect roaming client RSSI overlap and channel utilization across cells.
  4. Inspect associated bands steering outcomes and per-band utilization.

Explanation

Correct Answer

B:

For Arts Pavilion, the decisive mechanism is Strict priority queue use. Priority scheduling affects service latency but requires careful queue sizing. Inspect queue mappings weights and actual dropped/served traffic is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Multicast-to-unicast tradeoff, where multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

C:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing

D:

This is relevant to Band steering under load, where band steering can guide dual-band association but depends on real RF and client support In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is priority scheduling affects service latency but requires careful queue sizing
