Question 1150

At Bayside Campus, an endpoint sends rogue router advertisements and laptops select an unapproved IPv6 default router. What should the engineer implement first to correct the stated condition?

  1. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  2. Apply supported IPv6 RA guard at untrusted access interfaces with authorized router boundaries.
  3. Align native VLAN configuration and avoid using native VLAN for untrusted access where possible.
  4. Set the switchport as an access member of the correct VLAN with matching policy.

Explanation

Correct Answer

B:

For Bayside Campus, the decisive mechanism is IPv6 RA guard. IPv6 RA guard limits unauthorized router advertisements on access links. Apply supported IPv6 RA guard at untrusted access interfaces with authorized router boundaries establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is iPv6 RA guard limits unauthorized router advertisements on access links

C:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is iPv6 RA guard limits unauthorized router advertisements on access links

D:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is iPv6 RA guard limits unauthorized router advertisements on access links

Question 1151

At West Auditorium, a dense enterprise WLAN needs advisory roam guidance without hard-disconnecting phones. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Retain guest clients isolated from internal networks throughout portal state changes.
  2. Activate appropriate 802.11v BSS transition management and monitor client support.
  3. Adjust mounting antenna orientation and power using active RF measurements.
  4. Avoid excessive repeated transition requests that destabilize sessions.

Explanation

Correct Answers

B:

This is the implementation element for the West Auditorium case: 802.11v can suggest a transition; the client retains a role in the roaming decision. The specific action Enable appropriate 802.11v BSS transition management and monitor client support addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for West Auditorium. Avoid excessive repeated transition requests that destabilize sessions 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 Guest portal and role: Captive portal authentication and post-login role enforcement are separate controls. It does not resolve the 802.11v BSS transition requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is 802.11v can suggest a transition; the client retains a role in the roaming decision

C:

This may be a configuration step for AP power and cell geometry: AP placement and transmit power affect cell coverage and roaming boundaries. It does not resolve the 802.11v BSS transition requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is 802.11v can suggest a transition; the client retains a role in the roaming decision

Question 1152

At North Library, aPs have oversized cells and clients remain attached to distant radios after moving floors. Which practical change is best suited to this topology and its constraints?

  1. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.
  2. Use supported egress queue scheduling with bounded high-priority service treatment.
  3. Adjust transmit power with channel plan and measured minimum edge SNR.
  4. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.

Explanation

Correct Answer

C:

For North Library, the decisive mechanism is RF power tuning. Excess transmit power can increase interference and sticky-client behavior. Adjust transmit power with channel plan and measured minimum edge SNR establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

B:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

D:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

Question 1153

At Athletics Complex, a branch AP has 2.4-GHz saturation but laptop clients can use stronger 5-GHz service. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine cluster health tunnel termination count CPU and per-member forwarding.
  2. Cross-check per-band association distributions RSSI and steering responses.
  3. Cross-check spatial signal maps channel overlap and client roaming behavior.
  4. Examine portal redirect RADIUS or guest authorization events and the effective client role.

Explanation

Correct Answer

B:

For Athletics Complex, the decisive mechanism is Band steering behavior. Band steering guides capable clients toward suitable bands but client behavior still matters. Compare per-band association distributions RSSI and steering responses 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 band steering guides capable clients toward suitable bands but client behavior still matters

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 band steering guides capable clients toward suitable bands but client behavior still matters

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 band steering guides capable clients toward suitable bands but client behavior still matters

Question 1154

At East Student Center, a new SSID prompts users to trust an unknown RADIUS server certificate because the chain changed. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Provide valid server certificate and appropriate client trust configuration for EAP-TLS.
  2. Enforce role or group-based segmentation at the supported switching/gateway point.
  3. Secure log integrity retention and access according to data policy.
  4. Never direct users to blindly accept arbitrary authentication server certificates.

Explanation

Correct Answers

A:

This is the implementation element for the East Student Center case: Mutual TLS requires client-side confidence in the EAP server identity. The specific action Provide valid server certificate and appropriate client trust configuration for EAP-TLS addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for East Student Center. Never direct users to blindly accept arbitrary authentication server certificates 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 Campus microsegmentation: Role-based segmentation can limit lateral flows beyond simple VLAN separation. It does not resolve the EAP-TLS RADIUS server certificate requirement in East Student Center and is not one of the two controls requested. The direct mechanism here is mutual TLS requires client-side confidence in the EAP server identity

C:

This may be an ongoing precaution for RADIUS accounting traceability: Authentication and accounting provide different information and require separate configuration. It does not resolve the EAP-TLS RADIUS server certificate requirement in East Student Center and is not one of the two controls requested. The direct mechanism here is mutual TLS requires client-side confidence in the EAP server identity

Question 1155

At Lakeside Classroom, an access ACL was created but applied outbound instead of inbound, leaving IoT flows allowed. Which controlled acceptance test demonstrates the required behavior?

  1. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.
  2. Confirm 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. Permit a specifically authorized app and block the matching forbidden traffic.

Explanation

Correct Answer

D:

For Lakeside Classroom, the decisive mechanism is ACL direction and interface. Stateless ACL effectiveness depends on interface attachment direction and rule order. Permit a specifically authorized app and block the matching forbidden traffic supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order

Question 1156

At Technology Center, an AP was mounted above a metal ceiling and leaves a client shadow zone. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Perform an active site survey covering attenuation interference and realistic client density.
  2. Use an RF plan with reasonable channel reuse and channel width for expected density.
  3. Adjust mounting antenna orientation and power using active RF measurements.
  4. Plan nonoverlapping channel sets appropriate to the country and band.

Explanation

Correct Answer

C:

For Technology Center, the decisive mechanism is AP power and cell geometry. AP placement and transmit power affect cell coverage and roaming boundaries. Adjust mounting antenna orientation and power using active RF measurements establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

D:

This is relevant to Adjacent-channel overlap, where adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

Question 1157

At Main Data Center, two aggregation switches report OSPF Init and Down cycles after one interface timer change. Which configuration change best fits the network requirement and observed behavior?

  1. Enable matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Use supported ECMP and account for session hash distribution across eligible paths.
  3. Set compatible OSPF interface hello and dead intervals on both peers.
  4. Configure supported VRRP with consistent virtual IP and safe priority/failover behavior.

Explanation

Correct Answer

C:

For Main Data Center, the decisive mechanism is OSPF hello and dead timers. OSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists. Set compatible OSPF interface hello and dead intervals on both peers 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 Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

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 Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

Question 1158

At Engineering Tower, a role definition changed centrally yet one switch retains an outdated local enforcement policy. Which controlled configuration is most likely to restore the required service?

  1. Set up supported RADIUS accounting and consistent session identifier delivery.
  2. Publish supported downloadable role definitions and validate switch role retrieval.
  3. Enforce role or group-based segmentation at the supported switching/gateway point.
  4. Coordinate valid certificate chain rotation and trust propagation before expiry.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is Downloadable user roles. Downloadable roles coordinate centrally defined access controls with capable switch enforcement. Publish supported downloadable role definitions and validate switch role retrieval establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Engineering Tower case, Changing that neighboring feature does not implement the missing function. The specific mechanism is downloadable roles coordinate centrally defined access controls with capable switch enforcement

Configure matching supported OSPF authentication settings on intended neighbors 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 West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

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 West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the West Clinic case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

Question 1160

At Main Data Center, a university deployed 80-MHz 5-GHz channels to maximize single-client rates but dense classrooms now collide. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Select narrower supported channel width when needed for density and clean frequency reuse.
  2. Evaluate capacity not merely highest advertised PHY rate.
  3. Keep guest clients isolated from internal networks throughout portal state changes.
  4. Adjust mounting antenna orientation and power using active RF measurements.

Explanation

Correct Answers

A:

This is the implementation element for the Main Data Center case: Wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs. The specific action Select narrower supported channel width when needed for density and clean frequency reuse addresses the stated fault; the question also requires a persistent risk control.

B:

This is the continuing risk-control element for Main Data Center. Evaluate capacity not merely highest advertised PHY rate prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

C:

This may be an ongoing precaution for Guest portal and role: Captive portal authentication and post-login role enforcement are separate controls. It does not resolve the Channel width in density requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is wider channels raise peak rates but reduce nonoverlapping-channel reuse in busy designs

D:

This may be a configuration step for AP power and cell geometry: AP placement and transmit power affect cell coverage and roaming boundaries. It does not resolve the Channel width in density requirement in Main Data Center and is not one of the two controls requested.
