Question 470

At Riverside Building, a campus route policy should treat tagged partner prefixes differently from ordinary routes. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Choose compatible supported OSPF network type for the link topology.
  2. Set compatible OSPF interface hello and dead intervals on both peers.
  3. Match the approved BGP community in a route map and apply the correct import/export action.
  4. Align OSPF area ID and supported area type at both neighboring interfaces.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is BGP community route policy. BGP communities are policy labels requiring an explicit matching route policy. Match the approved BGP community in a route map and apply the correct import/export action establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to OSPF network type, where oSPF network type affects hello behavior and DR election on multiaccess segments In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bGP communities are policy labels requiring an explicit matching route policy

B:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bGP communities are policy labels requiring an explicit matching route policy

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 bGP communities are policy labels requiring an explicit matching route policy

Question 471

At Arts Pavilion, overlapping Wi-Fi 6 cells suffer contention even with distinguishable neighboring BSS colors. What operational rule should remain in place for later changes?

  1. Repeat surveys after major layout or material changes rather than trusting only plans.
  2. Follow regulatory channel availability and avoid indiscriminate band use.
  3. Do not assume BSS coloring overrides channel plan or power management.
  4. Avoid excessive AP transmit power that creates broad overlapping cells.

Explanation

Correct Answer

C:

For Arts Pavilion, the decisive mechanism is BSS coloring and spatial reuse. 802.11ax BSS coloring assists differentiation of overlapping transmissions under constraints. Do not assume BSS coloring overrides channel plan or power management 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 Arts Pavilion case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11ax BSS coloring assists differentiation of overlapping transmissions under constraints

B:

This is relevant to Adjacent-channel overlap, where adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing In the Arts Pavilion case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11ax BSS coloring assists differentiation of overlapping transmissions under constraints

D:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11ax BSS coloring assists differentiation of overlapping transmissions under constraints

Question 472

At Technology Center, a campus AP fleet has hundreds of harmless alerts while one critical gateway cluster fault is buried. Which postchange observation is the strongest evidence of correct operation?

  1. Read a test resource safely and confirm returned properties match the chosen selector.
  2. Generate a safe known event in the intended group and confirm delivery to the NOC.
  3. Repeat representative traffic and demonstrate counters stay within accepted thresholds.
  4. Verify a controlled internal failure affects only the intended sensor test.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is Central alert scope. A management alert must be scoped to the correct managed devices and policy. Generate a safe known event in the intended group and confirm delivery to the NOC supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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 Technology Center case, That test could pass while the actual user-facing requirement still fails.

For Technology Center, the decisive mechanism is RF predictive versus active survey. Predictive RF planning does not replace measured real-world attenuation and utilization. Inspect surveyed RSSI SNR channel use and roaming measurements at user positions is the most direct way to isolate this particular failure before making a change.

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, Those observations could be normal while the stated fault persists. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Technology Center case, Those observations could be normal while the stated fault persists. 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, Those observations could be normal while the stated fault persists. The specific mechanism is predictive RF planning does not replace measured real-world attenuation and utilization

Question 475

At Research Hub, a campus has two ISP exits and outbound traffic takes the less preferred link. Which postchange observation is the strongest evidence of correct operation?

  1. Verify Full adjacency and appropriate route propagation for a test network.
  2. Confirm outbound test routes prefer the intended link and fail over when withdrawn.
  3. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  4. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid.

Explanation

Correct Answer

B:

For Research Hub, the decisive mechanism is BGP local preference. Local preference guides outbound BGP best-path selection inside one autonomous system. Confirm outbound test routes prefer the intended link and fail over when withdrawn supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Research Hub case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

C:

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 Research Hub case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

D:

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 Research Hub case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

Question 476

At Main Data Center, a management-only deployment lacks a route from mgmt VRF to the monitoring collector. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Assess roaming and segmentation impacts before changing WLAN forwarding mode.
  2. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  3. Establish the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  4. Add an authorized management-VRF route and correct source reachability for the target service.

Explanation

Correct Answers

B:

This is the continuing risk-control element for Main Data Center. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF 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 Main Data Center case: AOS-CX management VRF and default forwarding VRF may have separate reachability. The specific action Add an authorized management-VRF route and correct source reachability for the target service addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for Bridge versus tunneled WLAN traffic: Bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy. It does not resolve the Management VRF reachability requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is aOS-CX management VRF and default forwarding VRF may have separate reachability

C:

This may be a configuration step for AP uplink physical mapping: AP service onboarding depends on both physical power and the upstream management network. It does not resolve the Management VRF reachability requirement in Main Data Center and is not one of the two controls requested. The direct mechanism here is aOS-CX management VRF and default forwarding VRF may have separate reachability
