Question 680

At Arts Pavilion, an IoT network must move from shared WPA2 PSK to stronger supported personal authentication. What measured or witnessed result should be required before signoff?

  1. Measure improved SNR and reduced retry rate without oversizing transmit power.
  2. Check coverage and capacity with representative real devices and occupancy.
  3. Connect modern clients securely and document any explicitly retained legacy devices.
  4. Observe lower airtime contention and stable throughput during concurrent client use.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is WPA3 SAE personal WLAN. SAE changes personal WLAN authentication compared with WPA2-PSK. Connect modern clients securely and document any explicitly retained legacy devices supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

B:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

D:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

Question 681

At Main Data Center, an access switch shows increasing runts and drops while the user complains of unstable wired access. What targeted evidence should the network engineer collect first?

  1. Examine routing table next-hop ARP and return-path filters hop by hop.
  2. Examine client effective VLAN AP forward mode tagged frames and DHCP lease.
  3. Examine topology-change events root path role and transition timing.
  4. Examine FCS CRC counters optical levels and negotiated mode.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is Physical-link errors. Layer 1/2 corruption can degrade packets even though link status remains up. Inspect FCS CRC counters optical levels and negotiated mode is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

B:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

Question 682

At East Student Center, a downstream access switch has one LAG member to each VSX chassis but the bundle never forms. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect loop-protect logs MAC flapping and abnormal broadcast traffic.
  2. Inspect LACP partner keys and VSX MC-LAG consistency on each chassis.
  3. Inspect cluster membership firmware compatibility load and tunnel health per gateway.
  4. Inspect VRRP advertisement state owner transitions and VLAN reachability.

Explanation

Correct Answer

B:

For East Student Center, the decisive mechanism is VSX MC-LAG. MC-LAG provides one downstream LAG across two independently managed VSX peers. Inspect LACP partner keys and VSX MC-LAG consistency on each chassis is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mC-LAG provides one downstream LAG across two independently managed VSX peers

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 East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mC-LAG provides one downstream LAG across two independently managed VSX peers

D:

This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is mC-LAG provides one downstream LAG across two independently managed VSX peers

Question 683

At Central Hall, one office radio remains overloaded while nearby capable APs have spare capacity. How should the engineer validate success against the stated requirement?

  1. Demonstrate pre-auth restrictions then post-auth Internet-only reachability.
  2. Demonstrate balanced eligible clients and improved user experience rather than forcing equal counts.
  3. Fail one member under a staged load and confirm expected client access.
  4. Measure acceptable coverage plus SNR at walking and seated client locations.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is ClientMatch balancing. ClientMatch can guide client association and roaming decisions based on RF and load. Verify balanced eligible clients and improved user experience rather than forcing equal counts supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

C:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

Question 684

At Learning Commons, the core receives hundreds of branch routes that fit an approved contiguous aggregate. Which ongoing safeguard best limits the specific risk after rollout?

  1. Keep route rollback and reachability checks before gateway migrations.
  2. Test preemption and split-brain behavior during a controlled pilot.
  3. Avoid summarizing nonexistent networks without blackhole and ownership review.
  4. Audit IPv4/IPv6 protocol operation separately rather than assuming dual-stack parity.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is OSPF area aggregation. OSPF area summarization reduces route detail but can hide gaps in address plans. Avoid summarizing nonexistent networks without blackhole and ownership review is an enduring limitation on the operational risk, not simply a one-time passing test.

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Learning Commons case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

D:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Learning Commons case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oSPF area summarization reduces route detail but can hide gaps in address plans

Question 685

At Garden Hall, a branch switch receives RADIUS accept but cannot apply the returned downloaded user role. What measured or witnessed result should be required before signoff?

  1. Correlate a test session and termination with the intended accounting records.
  2. Test allowed application connectivity and rejected unauthorized east-west traffic.
  3. Authenticate with newly issued certificates through the whole EAP-TLS exchange.
  4. Authenticate a test client and confirm the expected downloaded role rules actually apply.

Explanation

Correct Answer

D:

For Garden Hall, the decisive mechanism is Downloadable user roles. Downloadable roles coordinate centrally defined access controls with capable switch enforcement. Authenticate a test client and confirm the expected downloaded role rules actually apply supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

B:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

C:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

Question 686

Verify the rogue finding is substantiated without disrupting neighboring legitimate networks supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

D:

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 Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rogue identification differs from automatically assuming all same-name neighbor APs are malicious

Question 687

At Medical Annex, a hospital runs wide channels across many APs and has too few independent channels for reuse. What operational rule should remain in place for later changes?

  1. Retain rollout headroom and test gateway interoperability during upgrades.
  2. Evaluate capacity not merely highest advertised PHY rate.
  3. Avoid compensating for poor placement only by increasing transmit power.
  4. Retain guest clients isolated from internal networks throughout portal state changes.

Explanation

Correct Answer

B:

For Medical Annex, the decisive mechanism is Channel width in density. Wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs. Evaluate capacity not merely highest advertised PHY rate is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

C:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

D:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

Question 688

At North Residence, clients lose IPv4 connectivity when dynamic ARP inspection is enabled without expected bindings. What operational rule should remain in place for later changes?

  1. Avoid disabling all ARP protections to admit one untracked static device.
  2. Never expand a trunk to all VLANs merely to resolve one missing segment.
  3. Deny unapproved client VLAN changes and review port moves before deployment.
  4. Guard against arbitrary untrusted client VLAN tagging on shared ports.

Explanation

Correct Answer

A:

For North Residence, the decisive mechanism is ARP inspection dependency. Dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing. Avoid disabling all ARP protections to admit one untracked static device is an enduring limitation on the operational risk, not simply a one-time passing test.

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 North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

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 North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

Question 689

  2. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  3. Verify Full adjacency and appropriate route propagation for a test network.
  4. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid.

Explanation

Correct Answer

A:

For North Residence, the decisive mechanism is BGP prefix filtering. BGP route filters control prefix advertisement and must account for length matching. Prove only approved public aggregates are exported to the external peer supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

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 North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

C:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

D:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the North Residence case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching
