Question 430

At North Residence, clients lose IPv4 connectivity when dynamic ARP inspection is enabled without expected bindings. What measured or witnessed result should be required before signoff?

  1. See device traffic only in its assigned broadcast domain and expected address scope.
  2. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.
  3. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.
  4. Confirm legitimate ARP works while spoofed gateway replies are blocked.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is ARP inspection dependency. Dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing. Confirm legitimate ARP works while spoofed gateway replies are blocked supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

C:

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

Question 431

At Athletics Complex, a 5-GHz WLAN moves channels abruptly when radar detection triggers DFS. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect cluster health tunnel termination count CPU and per-member forwarding.
  2. Inspect DFS channel switch announcements radar events and AP radio logs.
  3. Compare spatial signal maps channel overlap and client roaming behavior.
  4. Inspect portal redirect RADIUS or guest authorization events and the effective client role.

Explanation

Correct Answer

B:

For Athletics Complex, the decisive mechanism is DFS event awareness. DFS channels require radar-related channel vacating behavior in supported regions. Inspect DFS channel switch announcements radar events and AP radio logs is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

C:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

D:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is dFS channels require radar-related channel vacating behavior in supported regions

Question 432

At East Student Center, a mixed-generation WLAN has a few low-rate clients consuming most shared radio time. What observable outcome would prove this repair actually works?

  1. Stress uplink and confirm voice stays timely without starvation of other classes.
  2. Measure improved user responsiveness without unacceptable legacy-client disruption.
  3. Demonstrate authorized voice gets its intended queue while bulk traffic does not.
  4. Generate concurrent voice and bulk traffic and compare latency under load.

Explanation

Correct Answer

B:

For East Student Center, the decisive mechanism is Airtime fairness QoS. Wireless performance must account for airtime occupancy as a shared resource. Measure improved user responsiveness without unacceptable legacy-client disruption supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

C:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

D:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource

Question 433

At Arts Pavilion, a softphone deployment experiences choppy audio over congested Wi-Fi while speed tests look good. Which practical change is best suited to this topology and its constraints?

  1. Tune supported band steering with proper 5-GHz coverage and compatibility checks.
  2. Evaluate supported multicast conversion and membership control for the audience size.
  3. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  4. Prioritize authenticated voice appropriately and reduce contention on affected paths.

Explanation

Correct Answer

D:

For Arts Pavilion, the decisive mechanism is Voice jitter and packet loss. Real-time voice quality depends on delay variation and loss more than raw peak throughput. Prioritize authenticated voice appropriately and reduce contention on affected paths establishes the needed configuration in the case rather than merely measuring a symptom.

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 Arts Pavilion case, Changing that neighboring feature does not implement the missing function. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

B:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

C:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Arts Pavilion case, Changing that neighboring feature does not implement the missing function. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

Question 434

At West Clinic, a campus UXI probe reaches the Internet but fails internal identity service authentication. What observable outcome would prove this repair actually works?

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

Explanation

Correct Answer

D:

For West Clinic, 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

A:

This is relevant to Central alert scope, where a management alert must be scoped to the correct managed devices and policy In the West Clinic 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

B:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the West Clinic 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 Port mirroring PCAP, where port mirroring copies selected frames for observation but is not a live forwarding path In the West Clinic 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 435

At Athletics Complex, a phone is consistently rejected because ClearPass assigns it to an unexpected policy branch. Which configuration change best fits the network requirement and observed behavior?

  1. Review the specific ClearPass service match authentication source and TLS decision.
  2. Trace the forward and reverse forwarding path including route recursion and ACLs.
  3. Correct STP root priorities and protect edge or downstream boundaries as appropriate.
  4. Correct SSID-to-VLAN and switch trunk membership for the intended segment.

Explanation

Correct Answer

A:

For Athletics Complex, the decisive mechanism is RADIUS Access-Reject root cause. An explicit RADIUS reject can come from credential validation or authorization policy. Review the specific ClearPass service match authentication source and TLS decision establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

D:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

Question 436

At New Teaching Block, a closet uplink fails and clients wait too long for the alternate Layer 2 path. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Retain rollback access during global STP region or root changes.
  2. Correct STP root priorities and protect edge or downstream boundaries as appropriate.
  3. Avoid bypassing AAA simply because DHCP is failing.
  4. Examine optics cabling transceiver support and duplex/speed at both ends before changing routes.

Explanation

Correct Answers

A:

This is the continuing risk-control element for New Teaching Block. Retain rollback access during global STP region or root changes 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 New Teaching Block case: STP role and root election determine the alternate Layer 2 forwarding path. The specific action Correct STP root priorities and protect edge or downstream boundaries as appropriate addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

C:

This may be an ongoing precaution for DHCP address-acquisition failure: Network authorization and DHCP allocation are separate stages requiring their own diagnostics. It does not resolve the STP convergence fault requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is sTP role and root election determine the alternate Layer 2 forwarding path

D:

This may be a configuration step for Physical-link errors: Layer 1/2 corruption can degrade packets even though link status remains up. It does not resolve the STP convergence fault requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is sTP role and root election determine the alternate Layer 2 forwarding path

Question 437

At North Library, a data-center uplink bundle stays logically up with just one member even though application capacity requires two. Which controlled configuration is most likely to restore the required service?

  1. Configure a separate reachable VSX keepalive path with valid source and peer addressing.
  2. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  3. Set a supported LAG minimum active-member threshold consistent with required capacity.
  4. Build a supported VSX ISL with enough capacity and verify peer state consistency.

Explanation

Correct Answer

C:

For North Library, the decisive mechanism is LACP minimum links. LAG interface health can depend on the configured minimum number of active members. Set a supported LAG minimum active-member threshold consistent with required capacity establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

B:

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 Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

D:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

Question 438

At North Residence, an outage makes ClearPass unavailable and a hospital phone cannot reach the emergency calling service. What observable outcome would prove this repair actually works?

  1. Maintain authenticated sessions through the expected timer cycle in a controlled test.
  2. Connect a managed laptop and verify authorized access only after authentication.
  3. Verify permitted NOC commands work and prohibited configuration commands fail.
  4. Simulate server failure and confirm emergency service remains without unrestricted campus access.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is Critical authentication fallback. Critical authorization controls how a port behaves if authentication service cannot be reached. Simulate server failure and confirm emergency service remains without unrestricted campus access 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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

C:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is critical authorization controls how a port behaves if authentication service cannot be reached

Question 439

At Lakeside Classroom, a 6-GHz WLAN configuration is inconsistent with management-frame protection expectations. What safety boundary prevents the same campus failure in future deployments?

  1. Audit implicit permits and policy defaults after group membership changes.
  2. Secure log integrity retention and access according to data policy.
  3. Document client compatibility before enforcing mandatory PMF across an established SSID.
  4. Monitor expiration windows and keep controlled rollback trust transitions.

Explanation

Correct Answer

C:

For Lakeside Classroom, the decisive mechanism is Protected management frames. Protected management frames reduce forgery of eligible robust management frames. Document client compatibility before enforcing mandatory PMF across an established SSID is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 protected management frames reduce forgery of eligible robust management frames

B:

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 protected management frames reduce forgery of eligible robust management frames

D:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Lakeside Classroom case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is protected management frames reduce forgery of eligible robust management frames

Question 440

At Learning Commons, a newly deployed employee switchport is connected but a laptop stays in an unauthorized port state. Which postchange observation is the strongest evidence of correct operation?

  1. Correlate test connect disconnect events to server accounting logs.
  2. Verify permitted NOC commands work and prohibited configuration commands fail.
  3. Connect a managed laptop and verify authorized access only after authentication.
  4. Maintain authenticated sessions through the expected timer cycle in a controlled test.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is Wired 802.1X port access. 802.1X authorizes port traffic through EAPOL and the authentication server decision. Connect a managed laptop and verify authorized access only after authentication supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RADIUS accounting for audit, where aAA accounting tracks session use separately from authentication and authorization In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision

B:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision

D:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.1X authorizes port traffic through EAPOL and the authentication server decision
