Question 120

At Athletics Complex, a user role updates correctly but accounting stop events are absent from the collector. What should be examined to confirm the actual failure mechanism?

  1. Examine TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Examine start interim and stop records mapped to the NAD and user.
  3. Examine association RSN capability and failed security negotiation status.
  4. Examine client TLS validation errors certificate SAN and trusted issuer store.

Explanation

Correct Answer

B:

For Athletics Complex, the decisive mechanism is RADIUS accounting traceability. Authentication and accounting provide different information and require separate configuration. Inspect start interim and stop records mapped to the NAD and user is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration

C:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration

D:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration

Question 121

At Riverside Building, an AP on a PoE trunk receives power but lacks a route to Central discovery services. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Treat AP port changes as staged network access changes rather than bypassing admission.
  2. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  3. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  4. Establish the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Riverside Building. Treat AP port changes as staged network access changes rather than bypassing admission prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

D:

This is the implementation element for the Riverside Building case: AP service onboarding depends on both physical power and the upstream management network. The specific action Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be an ongoing precaution for Management VRF reachability: AOS-CX management VRF and default forwarding VRF may have separate reachability. It does not resolve the AP uplink physical mapping requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is aP service onboarding depends on both physical power and the upstream management network

C:

This may be a configuration step for Central device onboarding: Cloud inventory association and device management connectivity are separate onboarding requirements. It does not resolve the AP uplink physical mapping requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is aP service onboarding depends on both physical power and the upstream management network

Question 122

At Lakeside Classroom, a phone-plus-PC port puts both devices into the voice segment after a new access template. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine interface VLAN mode learned MAC address and DHCP lease subnet.
  2. Examine untagged packet capture and both peers native VLAN configuration.
  3. Examine neighbor LLDP-MED TLVs and phone versus PC VLAN tags.
  4. Cross-check allowed VLAN list tagging and egress counters at both ends.

Explanation

Correct Answer

C:

For Lakeside Classroom, the decisive mechanism is Voice VLAN LLDP-MED. LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

B:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

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 Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

Question 123

At South Science Wing, a classroom full of small-packet clients sees high contention despite Wi-Fi 6 AP deployment. How should the engineer validate success against the stated requirement?

  1. Measure improved SNR and reduced retry rate without oversizing transmit power.
  2. Benchmark aggregate latency and throughput with realistic concurrent 802.11ax clients.
  3. Observe lower airtime contention and stable throughput during concurrent client use.
  4. Confirm coverage and capacity with representative real devices and occupancy.

Explanation

Correct Answer

B:

For South Science Wing, the decisive mechanism is OFDMA efficiency. OFDMA divides channel resources among eligible simultaneous users. Benchmark aggregate latency and throughput with realistic concurrent 802.11ax clients 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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

Question 124

At Main Data Center, a voice-focused wing experiences rare roaming interruptions when APs leave DFS channels. What should be examined to confirm the actual failure mechanism?

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

Explanation

Correct Answer

D:

For Main Data Center, 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 Main Data Center 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

B:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Main Data Center 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 Main Data Center 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 125

At Technology Center, a handheld scans an AP yet fails to join after an advertised WLAN capability change. How should the engineer validate success against the stated requirement?

  1. Sustain the full AP or phone feature load without PoE budget alarms or resets.
  2. Prove the client completes association and then separately completes its enterprise authentication.
  3. Match the discovered neighbor port to the documented physical switch path.
  4. Run bidirectional throughput tests with no late collisions or increasing CRC errors.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is 802.11 association sequence. 802.11 discovery and association occur before user traffic can be successfully forwarded. Prove the client completes association and then separately completes its enterprise authentication supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

C:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

D:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

Question 126

At Transit Operations Center, a cloned distribution switch shares an OSPF router ID and adjacency becomes unstable. Which test best differentiates real success from a merely healthy status light?

  1. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  2. Generate many independent test flows and compare distribution without requiring per-packet balance.
  3. Show stable Full adjacencies with distinct peer identities.
  4. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is OSPF router ID uniqueness. An OSPF router ID identifies a routing instance independently of VLAN labels. Show stable Full adjacencies with distinct peer identities supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

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 Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

D:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

Question 127

At New Teaching Block, a laptop receives Access-Accept but its switchport remains assigned to an unauthenticated VLAN. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Version enforcement profiles and test against the deployed switch software.
  2. Return supported VLAN or role attributes that match network enforcement configuration.
  3. Keep emergency break-glass administration documented and monitored.
  4. Tune supported reauthentication and EAP timers based on measured client/server behavior.

Explanation

Correct Answers

A:

This is the continuing risk-control element for New Teaching Block. Version enforcement profiles and test against the deployed switch software 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: An Access-Accept alone does not guarantee the intended authorization role was applied. The specific action Return supported VLAN or role attributes that match network enforcement configuration addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

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 ClearPass enforcement attributes requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is an Access-Accept alone does not guarantee the intended authorization role was applied

D:

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 ClearPass enforcement attributes requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is an Access-Accept alone does not guarantee the intended authorization role was applied

Question 128

At Riverside Building, a streaming classroom sees multicast stop when the only IGMP querier disappears. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Never expand a trunk to all VLANs merely to resolve one missing segment.
  2. Activate supported IGMP snooping with a reachable querier for the multicast VLAN.
  3. Preserve querier redundancy and monitor joins when topology changes.
  4. Establish the switchport as an access member of the correct VLAN with matching policy.

Explanation

Correct Answers

B:

This is the implementation element for the Riverside Building case: IGMP snooping constrains IPv4 multicast by observed group memberships. The specific action Enable supported IGMP snooping with a reachable querier for the multicast VLAN addresses the stated fault; the question also requires a persistent risk control.

C:

This is the continuing risk-control element for Riverside Building. Maintain querier redundancy and monitor joins when topology changes 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 Tagged trunk allowlist: A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. It does not resolve the IGMP multicast snooping requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is iGMP snooping constrains IPv4 multicast by observed group memberships

D:

This may be a configuration step for Access VLAN classification: An access port carries untagged frames in one configured access VLAN. It does not resolve the IGMP multicast snooping requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is iGMP snooping constrains IPv4 multicast by observed group memberships

Question 129

At Engineering Tower, a campus branch configured an application route through a decommissioned firewall interface. What targeted evidence should the network engineer collect first?

  1. Examine IPv6 link-local neighbors OSPFv3 interface area and router ID.
  2. Examine relay forwarded packets GIADDR server routes and ACL logs.
  3. Examine per-VRF route tables interfaces and deliberately leaked prefixes.
  4. Examine route table recursive next-hop resolution and ARP reachability.

Explanation

Correct Answer

D:

For Engineering Tower, the decisive mechanism is Static route next hop. A static route only forwards as intended when its next hop can be resolved. Inspect route table recursive next-hop resolution and ARP reachability is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

B:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

C:

This is relevant to VRF segmentation routing, where vRFs maintain separate forwarding and routing instances on supported devices In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

Question 130

At Central Hall, a new campus fiber uplink should be preferred but interface costs retain old values. Which configuration change best fits the network requirement and observed behavior?

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Establish intentional OSPF interface cost reflecting primary and backup path design.
  3. Ensure relay source and server return routing permit both directions of the DHCP exchange.
  4. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Set intentional OSPF interface cost reflecting primary and backup path design establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

C:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
