Question 30

At Bayside Campus, an auditorium has multi-antenna APs but most clients are single-stream devices. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Track both RF signal and noise as part of acceptance tests.
  2. Perform an active site survey covering attenuation interference and realistic client density.
  3. Retain mixed-client fairness and RF design rather than relying only on antenna count.
  4. Assess compatible multi-user MIMO support and clients for the expected traffic direction.

Explanation

Correct Answers

C:

This is the continuing risk-control element for Bayside Campus. Retain mixed-client fairness and RF design rather than relying only on antenna count 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 Bayside Campus case: MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. The specific action Assess compatible multi-user MIMO support and clients for the expected traffic direction addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for RSSI and SNR differentiation: SNR accounts for interference floor; RSSI alone does not predict useful wireless throughput. It does not resolve the MU-MIMO application requirement in Bayside Campus and is not one of the two controls requested. The direct mechanism here is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

B:

This may be a configuration step for RF predictive versus active survey: Predictive RF planning does not replace measured real-world attenuation and utilization. It does not resolve the MU-MIMO application requirement in Bayside Campus and is not one of the two controls requested. The direct mechanism here is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 31

At Technology Center, two campus blocks disagree on MST region name and revision despite the same VLAN plan. What measured or witnessed result should be required before signoff?

  1. Confirm a client retains default-gateway reachability across a member failure.
  2. Simulate controlled ISL loss and verify the documented split-brain prevention behavior.
  3. Confirm intended MST instances and forwarding paths after a controlled topology event.
  4. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists.

Explanation

Correct Answer

C:

For Technology Center, the decisive mechanism is MSTP region identity. MST region identity depends on matching configuration, not only the switch hostname. Confirm intended MST instances and forwarding paths after a controlled topology event supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

D:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mST region identity depends on matching configuration, not only the switch hostname

Question 32

At Technology Center, a library floor has mapped AP placements but thick fire doors cause unexpected coverage loss. Which controlled acceptance test demonstrates the required behavior?

  1. Measure acceptable coverage plus SNR at walking and seated client locations.
  2. Confirm coverage and capacity with representative real devices and occupancy.
  3. Verify pre-auth restrictions then post-auth Internet-only reachability.
  4. Fail one member under a staged load and confirm expected client access.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is RF predictive versus active survey. Predictive RF planning does not replace measured real-world attenuation and utilization. Confirm coverage and capacity with representative real devices and occupancy supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

C:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

D:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

Question 33

At Riverside Building, a management VRF must reach a collector without leaking its routes to the user VRF. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Install a valid static route with a resolvable next hop and appropriate administrative distance.
  2. Apply supported VRFs and explicit approved import/export or transit policy for any crossing.
  3. Restore an authorized default next hop and deliberate route preferences.
  4. Synchronize OSPF area ID and supported area type at both neighboring interfaces.

Explanation

Correct Answer

B:

For Riverside Building, the decisive mechanism is VRF segmentation routing. VRFs maintain separate forwarding and routing instances on supported devices. Use supported VRFs and explicit approved import/export or transit policy for any crossing establishes the needed configuration in the case rather than merely measuring a symptom.

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

C:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

D:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

Question 34

At Transit Operations Center, dual-band clients crowd 2.4-GHz radios despite healthy 5-GHz capacity. What measured or witnessed result should be required before signoff?

  1. Measure acceptable coverage plus SNR at walking and seated client locations.
  2. Fail one member under a staged load and confirm expected client access.
  3. Show eligible dual-band clients use the preferred band without losing connectivity.
  4. Verify pre-auth restrictions then post-auth Internet-only reachability.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is Band steering behavior. Band steering guides capable clients toward suitable bands but client behavior still matters. Show eligible dual-band clients use the preferred band without losing connectivity supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is band steering guides capable clients toward suitable bands but client behavior still matters

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. 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 Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is band steering guides capable clients toward suitable bands but client behavior still matters

Question 35

At Administration Block, an uplink forwards VLAN 120 but silently drops newly introduced VLAN 350. What measured or witnessed result should be required before signoff?

  1. Run controlled large-payload tests and confirm reliable path MTU behavior.
  2. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.
  3. Demonstrate the phone uses the voice VLAN while the PC remains in the data VLAN.
  4. Permit a specifically authorized app and block the matching forbidden traffic.

Explanation

Correct Answer

B:

For Administration Block, the decisive mechanism is Tagged trunk allowlist. A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

C:

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 Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

D:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Administration Block case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration

Question 36

At Arts Pavilion, a softphone deployment experiences choppy audio over congested Wi-Fi while speed tests look good. Which investigation most directly explains why the intended service is not working?

  1. Examine associated bands steering outcomes and per-band utilization.
  2. Examine input DSCP markings trust state and egress queue classification.
  3. Examine one-way delay jitter loss DSCP WMM and radio retry data.
  4. Examine group subscriptions multicast airtime and converted frame counts.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is Voice jitter and packet loss. Real-time voice quality depends on delay variation and loss more than raw peak throughput. Inspect one-way delay jitter loss DSCP WMM and radio retry data is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

D:

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 Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

Question 37

At Technology Center, a branch has two default routes but prefers the backup due to unexpected distance. Which change-management constraint best guards against recurrence?

  1. Secure internal prefixes with appropriate specific routes and reject unwanted default announcements.
  2. Audit IPv4/IPv6 protocol operation separately rather than assuming dual-stack parity.
  3. Review helper addresses and routes together during subnet migrations.
  4. Test preemption and split-brain behavior during a controlled pilot.

Explanation

Correct Answer

A:

For Technology Center, the decisive mechanism is Default route selection. Default route 0.0.0.0/0 applies when no more specific IPv4 route matches. Protect internal prefixes with appropriate specific routes and reject unwanted default announcements is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

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 Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

Question 38

At Transit Operations Center, a managed conference provider changes STP priority and moves the campus root unexpectedly. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Do not enable root guard on paths that legitimately must learn a different root.
  2. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  3. Do not enable jumbo frames on one device without validating intermediate hops.
  4. Apply root guard to the correct designated downstream boundary port.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Transit Operations Center. Do not enable root guard on paths that legitimately must learn a different root 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 Transit Operations Center case: Root guard prevents a protected port from accepting a superior root advertisement. The specific action Apply root guard to the correct designated downstream boundary port addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be a configuration step for Voice VLAN LLDP-MED: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. It does not resolve the Root guard downstream requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is root guard prevents a protected port from accepting a superior root advertisement

C:

This may be an ongoing precaution for End-to-end MTU and frames: A path's effective MTU is limited by the smallest supported segment and encapsulation overhead. It does not resolve the Root guard downstream requirement in Transit Operations Center and is not one of the two controls requested. The direct mechanism here is root guard prevents a protected port from accepting a superior root advertisement

Question 39

At Medical Annex, a routed user VLAN fails when the primary distribution gateway is restarted. What should be examined to confirm the actual failure mechanism?

  1. Compare configured and operational gateway state and ARP entries on both VSX peers.
  2. Inspect keepalive reachability and failure signals independently of ISL health.
  3. Inspect ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  4. Inspect VRRP advertisement state owner transitions and VLAN reachability.

Explanation

Correct Answer

D:

For Medical Annex, the decisive mechanism is VRRP redundant gateway. VRRP supplies virtual first-hop gateway failover between eligible routing peers. Inspect VRRP advertisement state owner transitions and VLAN reachability is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Medical Annex case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

Question 40

At Convention Center, a CX 6200 stack ring becomes a line when one stacking cable is unplugged. What measured or witnessed result should be required before signoff?

  1. Show the expected members in one management system and recover from a single link fault.
  2. Introduce a safe lab loop and verify the intended port protection without damaging trunks.
  3. Restart the primary in a lab and confirm the virtual address stays reachable.
  4. Fail one gateway in a pilot and verify tunneled clients reconnect through eligible members.

Explanation

Correct Answer

A:

For Convention Center, the decisive mechanism is VSF member order. VSF combines compatible access switches into a unified stack control plane. Show the expected members in one management system and recover from a single link fault supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSF combines compatible access switches into a unified stack control plane

C:

This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSF combines compatible access switches into a unified stack control plane

D:

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 Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is vSF combines compatible access switches into a unified stack control plane
