Question 890

At Technology Center, contractors successfully authenticate but receive full staff network permissions. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Keep least-privilege default roles and audit policy ordering.
  2. Enforce role or group-based segmentation at the supported switching/gateway point.
  3. Return and enforce the correct identity-based role or VLAN through ClearPass and access infrastructure.
  4. Protect log integrity retention and access according to data policy.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Technology Center. Keep least-privilege default roles and audit policy ordering prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

C:

This is the implementation element for the Technology Center case: ClearPass decides authorization outcomes while network devices enforce assigned policy. The specific action Return and enforce the correct identity-based role or VLAN through ClearPass and access infrastructure addresses the stated fault; the question also requires a persistent risk control.

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 ClearPass role-based enforcement requirement in Technology Center and is not one of the two controls requested. The direct mechanism here is clearPass decides authorization outcomes while network devices enforce assigned policy

D:

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 ClearPass role-based enforcement requirement in Technology Center and is not one of the two controls requested. The direct mechanism here is clearPass decides authorization outcomes while network devices enforce assigned policy

Question 891

At South Science Wing, a WLAN voice service is mapped to background access category despite proper wired DSCP. Which preventive control is most relevant to this scenario over time?

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

Explanation

Correct Answer

A:

For South Science Wing, 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

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 South Science Wing 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

C:

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 South Science Wing 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 South Science Wing 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 892

At Garden Hall, a campus routing change assigns a core uplink to a stub area on only one side. Which postchange observation is the strongest evidence of correct operation?

  1. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  2. Demonstrate Full adjacency and appropriate route propagation for a test network.
  3. Check appropriate IPv6 routes are learned and prefixes stay reachable.
  4. Generate many independent test flows and compare distribution without requiring per-packet balance.

Explanation

Correct Answer

B:

For Garden Hall, the decisive mechanism is OSPF area membership. OSPF neighbors on a link must agree on essential area and protocol parameters. Verify Full adjacency and appropriate route propagation for a test network 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 Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

D:

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 Garden Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

Question 893

At Lakeside Classroom, a new WLAN attempts to force all devices to 5 GHz and disconnects legacy scanners. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Tune supported band steering with proper 5-GHz coverage and compatibility checks.
  2. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  3. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.
  4. Apply supported egress queue scheduling with bounded high-priority service treatment.

Explanation

Correct Answer

A:

For Lakeside Classroom, the decisive mechanism is Band steering under load. Band steering can guide dual-band association but depends on real RF and client support. Tune supported band steering with proper 5-GHz coverage and compatibility checks establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

C:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

D:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is band steering can guide dual-band association but depends on real RF and client support

Question 894

At Central Hall, one office radio remains overloaded while nearby capable APs have spare capacity. What should be examined to confirm the actual failure mechanism?

  1. Examine cluster health tunnel termination count CPU and per-member forwarding.
  2. Cross-check spatial signal maps channel overlap and client roaming behavior.
  3. Examine ClientMatch decisions client capability and candidate AP channel utilization.
  4. Examine portal redirect RADIUS or guest authorization events and the effective client role.

Explanation

Correct Answer

C:

For Central Hall, the decisive mechanism is ClientMatch balancing. ClientMatch can guide client association and roaming decisions based on RF and load. Inspect ClientMatch decisions client capability and candidate AP channel utilization 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 Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

B:

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, Those observations could be normal while the stated fault persists. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

D:

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, Those observations could be normal while the stated fault persists. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

Question 895

At Engineering Tower, employees report that a wireless SSID associates yet DNS queries time out sporadically. Which investigation most directly explains why the intended service is not working?

  1. Inspect CRC input drops queue discards and rate correlation on the affected port.
  2. Inspect requested API version selector depth and response attribute groups.
  3. Inspect per-test DHCP DNS HTTP stage timing and sensor health.
  4. Inspect device clock NTP sync severity filters and log delivery failures.

Explanation

Correct Answer

C:

For Engineering Tower, the decisive mechanism is UXI client experience probes. UXI sensors run synthetic end-user workflows to reveal service-layer failures. Inspect per-test DHCP DNS HTTP stage timing and sensor health is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Switch telemetry counters, where interface counters help distinguish physical corruption from congestion drops In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

B:

This is relevant to REST API selector use, where rEST representation selection and HTTP method choice affect what configuration is retrieved or changed In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

D:

This is relevant to Syslog timestamps and forwarding, where system logging accuracy needs both transport and synchronized timestamps In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

Question 896

At South Science Wing, a classroom full of small-packet clients sees high contention despite Wi-Fi 6 AP deployment. What safety boundary prevents the same campus failure in future deployments?

  1. Repeat surveys after major layout or material changes rather than trusting only plans.
  2. Avoid excessive AP transmit power that creates broad overlapping cells.
  3. Retain coexistence checks for clients that do not support OFDMA.
  4. Track both RF signal and noise as part of acceptance tests.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is OFDMA efficiency. OFDMA divides channel resources among eligible simultaneous users. Retain coexistence checks for clients that do not support OFDMA is an enduring limitation on the operational risk, not simply a one-time passing test.

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 South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

B:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

D:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is oFDMA divides channel resources among eligible simultaneous users

Question 897

At Riverside Building, a management VRF must reach a collector without leaking its routes to the user VRF. Which preventive control is most relevant to this scenario over time?

  1. Secure internal prefixes with appropriate specific routes and reject unwanted default announcements.
  2. Review area settings as paired changes and preserve routing rollback.
  3. Prevent accidental broad route leaks across security domains.
  4. Retain route rollback and reachability checks before gateway migrations.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is VRF segmentation routing. VRFs maintain separate forwarding and routing instances on supported devices. Prevent accidental broad route leaks across security domains is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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 Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

B:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

D:

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 Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

Question 898

At Arts Pavilion, a ClearPass policy returns a VLAN absent on the actual access switch. Which test best differentiates real success from a merely healthy status light?

  1. Demonstrate the accepted identity receives the intended permissions and IP subnet.
  2. Demonstrate the registered headless device gets its narrow role while an unknown MAC is denied.
  3. Demonstrate a test contractor receives the correct restricted VLAN and no employee services.
  4. Block the primary in a lab and verify configured fallback behavior.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is Dynamic VLAN on wired port. Dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support. Verify a test contractor receives the correct restricted VLAN and no employee services supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

B:

This is relevant to MAB for headless IoT, where mAB is a weaker fallback identity mechanism than certificate-based 802.1X In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails.
