Question 220

At Technology Center, a lobby guest VLAN shares unrestricted routing with employee printers. How should the engineer validate success against the stated requirement?

  1. Demonstrate Internet access and blocked access to internal test endpoints.
  2. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  3. Correlate a test session and termination with the intended accounting records.
  4. Test allowed application connectivity and rejected unauthorized east-west traffic.

Explanation

Correct Answer

A:

For Technology Center, the decisive mechanism is Guest segmentation. Guest network segmentation depends on enforced policy, not only SSID naming. Demonstrate Internet access and blocked access to internal test endpoints supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

D:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is guest network segmentation depends on enforced policy, not only SSID naming

Question 221

At Administration Block, an API monitoring script requests config values but accidentally reads only interface status attributes. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Use documented REST selectors and read writable fields before controlled updates.
  2. Grant least-privilege API access and back up intended modifications.
  3. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.
  4. Protect sensitive mirrored payloads and remove temporary sessions after testing.

Explanation

Correct Answers

A:

This is the implementation element for the Administration Block case: REST representation selection and HTTP method choice affect what configuration is retrieved or changed. The specific action Use documented REST selectors and read writable fields before controlled updates addresses the stated fault; the question also requires a persistent risk control.

B:

This is the continuing risk-control element for Administration Block. Grant least-privilege API access and back up intended modifications prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

C:

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 REST API selector use requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

D:

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 REST API selector use requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

Question 222

At West Clinic, a new 6-GHz SSID is absent from older client devices in a mixed fleet. What operational rule should remain in place for later changes?

  1. Avoid compensating for poor placement only by increasing transmit power.
  2. Do not assume all 5-GHz-capable clients support 6-GHz discovery or security.
  3. Retain guest clients isolated from internal networks throughout portal state changes.
  4. Retain rollout headroom and test gateway interoperability during upgrades.

Explanation

Correct Answer

B:

For West Clinic, the decisive mechanism is 6-GHz WLAN eligibility. 6-GHz operation requires compatible radios security and jurisdiction-specific channels. Do not assume all 5-GHz-capable clients support 6-GHz discovery or security is an enduring limitation on the operational risk, not simply a one-time passing test.

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 West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

D:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

Question 223

At Learning Commons, the core receives hundreds of branch routes that fit an approved contiguous aggregate. Which postchange observation is the strongest evidence of correct operation?

  1. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  2. Confirm the intended aggregate is learned and authorized internal subnets stay reachable.
  3. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  4. Fail one gateway and confirm uninterrupted client default-route access within design targets.

Explanation

Correct Answer

B:

For Learning Commons, the decisive mechanism is OSPF area aggregation. OSPF area summarization reduces route detail but can hide gaps in address plans. Confirm the intended aggregate is learned and authorized internal subnets stay reachable supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

Question 224

At Bayside Campus, an auditorium has multi-antenna APs but most clients are single-stream devices. Which controlled configuration is most likely to restore the required service?

  1. Use an RF plan with reasonable channel reuse and channel width for expected density.
  2. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  3. Perform an active site survey covering attenuation interference and realistic client density.
  4. Assess compatible multi-user MIMO support and clients for the expected traffic direction.

Explanation

Correct Answer

D:

For Bayside Campus, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Assess compatible multi-user MIMO support and clients for the expected traffic direction establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 225

At North Residence, a campus core VSX design uses an undersized ISL and traffic fails during one access uplink outage. How should the engineer validate success against the stated requirement?

  1. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists.
  2. Restart the primary in a lab and confirm the virtual address stays reachable.
  3. Fail one gateway in a pilot and verify tunneled clients reconnect through eligible members.
  4. Introduce a safe lab loop and verify the intended port protection without damaging trunks.

Explanation

Correct Answer

A:

For North Residence, the decisive mechanism is VSX inter-switch link. VSX peers synchronize selected state over an ISL while retaining independent control planes. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

C:

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

D:

This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

Question 226

At Research Hub, a wired label printer has no 802.1X supplicant and remains blocked on an authenticated access port. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Use approved MAC authentication with profiling and strictly limited authorization.
  2. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  3. Keep emergency break-glass administration documented and monitored.
  4. Treat MAC addresses as spoofable identifiers and limit privileges.

Explanation

Correct Answers

A:

This is the implementation element for the Research Hub case: MAB is a weaker fallback identity mechanism than certificate-based 802.1X. The specific action Use approved MAC authentication with profiling and strictly limited authorization addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Research Hub. Treat MAC addresses as spoofable identifiers and limit privileges 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 Supplicant reauthentication intervals: Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. It does not resolve the MAB for headless IoT requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

C:

This may be an ongoing precaution for TACACS+ admin AAA distinction: Administrative command authorization and client-port 802.1X solve different AAA problems. It does not resolve the MAB for headless IoT requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is mAB is a weaker fallback identity mechanism than certificate-based 802.1X

Question 227

At South Science Wing, a data uplink shows increasing egress queue drops during backup windows. Which preventive control is most relevant to this scenario over time?

  1. Allow documented compatibility cases instead of forcing a universal band cutoff.
  2. Avoid exceeding regulatory EIRP limits or creating asymmetric AP/client link budgets.
  3. Assess scaling limits and do not assume conversion always reduces total transmissions.
  4. Avoid assuming average link utilization proves absence of microbursts.

Explanation

Correct Answer

D:

For South Science Wing, the decisive mechanism is Congestion buffer drops. Short congestion bursts can exhaust queues before low-frequency monitoring notices. Avoid assuming average link utilization proves absence of microbursts is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

B:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

C:

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 South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

Question 228

At Hillcrest Campus, a Wi-Fi phone loses audio for seconds when moving across APs despite good RF overlap. Which investigation most directly explains why the intended service is not working?

  1. Capture association FT and EAP timing around the roam event.
  2. Inspect FCS CRC counters optical levels and negotiated mode.
  3. Inspect authorized port VLAN DHCP DISCOVER/OFFER and relay counters.
  4. Inspect routing table next-hop ARP and return-path filters hop by hop.

Explanation

Correct Answer

A:

For Hillcrest Campus, the decisive mechanism is Roaming authentication stalls. Roaming interruptions can arise from authentication delay rather than RF coverage alone. Capture association FT and EAP timing around the roam event is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

C:

This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

D:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

Question 229

At Hillcrest Campus, an AP 6 GHz radio never activates while PoE is negotiated at a low class. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect route table source interface and ACLs in the actual management VRF.
  2. Inspect AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  3. Inspect advertised versus delivered power and AP reduced-function power mode.
  4. Inspect serial record device assignment onboarding logs DNS and outbound management connectivity.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Inspect advertised versus delivered power and AP reduced-function power mode is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

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 Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

D:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Hillcrest Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

Question 230

At South Science Wing, a user logs in successfully but accounting stop records never reach ClearPass. Which configuration change best fits the network requirement and observed behavior?

  1. Activate appropriate RADIUS start/interim/stop accounting to the approved server.
  2. Activate supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  3. Set up appropriate RADIUS failover and tested timeout/retry settings.
  4. Return supported VLAN or role attributes that match network enforcement configuration.

Explanation

Correct Answer

A:

For South Science Wing, the decisive mechanism is RADIUS accounting for audit. AAA accounting tracks session use separately from authentication and authorization. Enable appropriate RADIUS start/interim/stop accounting to the approved server establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

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 South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

D:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization
