Question 950

At Hillcrest Campus, a fiber handoff has link errors after mismatching optic wavelength and connector types. Which controlled configuration is most likely to restore the required service?

  1. Add an authorized management-VRF route and correct source reachability for the target service.
  2. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  3. Select supported transceivers fiber type wavelength and distance for both endpoints.
  4. Bind the device to its approved group and review group-level settings and local overrides.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Fiber optic transceiver fit. Optical compatibility relies on physical medium optics reach and platform support. Select supported transceivers fiber type wavelength and distance for both endpoints establishes the needed configuration in the case rather than merely measuring a symptom.

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is optical compatibility relies on physical medium optics reach and platform support

B:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Hillcrest Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is optical compatibility relies on physical medium optics reach and platform support

D:

The specific mechanism is optical compatibility relies on physical medium optics reach and platform support

Question 951

At North Library, a data-center uplink bundle stays logically up with just one member even though application capacity requires two. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Assess reduced-capacity behavior before enabling automatic LAG shutdown.
  2. Maintain cluster software and resource headroom during rolling changes.
  3. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  4. Set a supported LAG minimum active-member threshold consistent with required capacity.

Explanation

Correct Answers

A:

This is the continuing risk-control element for North Library. Assess reduced-capacity behavior before enabling automatic LAG shutdown 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 North Library case: LAG interface health can depend on the configured minimum number of active members. The specific action Set a supported LAG minimum active-member threshold consistent with required capacity addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be an ongoing precaution for AOS 10 gateway cluster: An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. It does not resolve the LACP minimum links requirement in North Library and is not one of the two controls requested. The direct mechanism here is lAG interface health can depend on the configured minimum number of active members

C:

This may be a configuration step for VSX inter-switch link: VSX peers synchronize selected state over an ISL while retaining independent control planes. It does not resolve the LACP minimum links requirement in North Library and is not one of the two controls requested. The direct mechanism here is lAG interface health can depend on the configured minimum number of active members

Question 952

At Riverside Building, an AP on a PoE trunk receives power but lacks a route to Central discovery services. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine serial record device assignment onboarding logs DNS and outbound management connectivity.
  2. Examine configuration inheritance group membership and effective setting differences.
  3. Examine route table source interface and ACLs in the actual management VRF.
  4. Examine AP boot sequence neighbor LLDP uplink VLAN and address acquisition.

Explanation

Correct Answer

D:

For Riverside Building, the decisive mechanism is AP uplink physical mapping. AP service onboarding depends on both physical power and the upstream management network. Inspect AP boot sequence neighbor LLDP uplink VLAN and address acquisition is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

C:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Riverside Building case, Those observations could be normal while the stated fault persists. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

Question 953

At North Residence, an AOS-CX uplink migrates to Layer 3 but VLAN interfaces have incorrect IP prefixes. What should the engineer implement first to correct the stated condition?

  1. Set up correct SVI IP gateway and inter-VLAN routing with suitable ACLs.
  2. Permit required tagged VLANs on both trunk interfaces while restricting unnecessary VLANs.
  3. Establish the switchport as an access member of the correct VLAN with matching policy.
  4. Synchronize native VLAN configuration and avoid using native VLAN for untrusted access where possible.

Explanation

Correct Answer

A:

For North Residence, the decisive mechanism is SVI routing enablement. An SVI is the Layer 3 gateway for an associated Layer 2 VLAN. Configure correct SVI IP gateway and inter-VLAN routing with suitable ACLs establishes the needed configuration in the case rather than merely measuring a symptom.

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

D:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

Question 954

At Arts Pavilion, an IoT network must move from shared WPA2 PSK to stronger supported personal authentication. Which observation most directly isolates the likely cause before any change?

  1. Examine co-channel AP visibility airtime utilization and contention counters.
  2. Examine surveyed RSSI SNR channel use and roaming measurements at user positions.
  3. Cross-check RSSI noise floor SNR and retransmissions per affected client.
  4. Examine AKM suite and SAE handshake failure codes on incompatible stations.

Explanation

Correct Answer

D:

For Arts Pavilion, the decisive mechanism is WPA3 SAE personal WLAN. SAE changes personal WLAN authentication compared with WPA2-PSK. Inspect AKM suite and SAE handshake failure codes on incompatible stations is the most direct way to isolate this particular failure before making a change.

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 Arts Pavilion case, Those observations could be normal while the stated fault persists. 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, Those observations could be normal while the stated fault persists. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

Question 955

At Riverside Building, a wireless SSID has no voice prioritization so delay increases during heavy uploads. Which change-management constraint best guards against recurrence?

  1. Assess scaling limits and do not assume conversion always reduces total transmissions.
  2. Allow documented compatibility cases instead of forcing a universal band cutoff.
  3. Preserve consistent DSCP-to-WMM mapping end to end.
  4. Avoid exceeding regulatory EIRP limits or creating asymmetric AP/client link budgets.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is WMM access categories. 802.11e WMM prioritizes wireless contention via different access categories. Maintain consistent DSCP-to-WMM mapping end to end is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

B:

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 Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

D:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories

Question 956

At Transit Operations Center, a voice handset needs faster discovery of neighboring BSSIDs while walking floors. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Review client feature compatibility rather than assuming reports force movement.
  2. Activate appropriate 802.11k neighbor report support on the intended enterprise WLAN.
  3. Retain 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 continuing risk-control element for Transit Operations Center. Check client feature compatibility rather than assuming reports force movement 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 Transit Operations Center case: 802.11k provides radio-resource neighbor information to assist client decisions. The specific action Enable appropriate 802.11k neighbor report support on the intended enterprise WLAN addresses the stated fault; the question also requires a persistent risk control.

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 802.11k neighbor information requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is 802.11k provides radio-resource neighbor information to assist client decisions

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 802.11k neighbor information requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is 802.11k provides radio-resource neighbor information to assist client decisions

For East Student Center, the decisive mechanism is Multicast optimization WLAN. Wireless multicast often uses conservative rates and can impair shared medium efficiency. Prove subscribed clients receive the stream without saturating all WLAN airtime supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless multicast often uses conservative rates and can impair shared medium efficiency

C:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the East Student Center case, That test could pass while the actual user-facing requirement still fails.
