Question 1130

At Main Data Center, two aggregation switches report OSPF Init and Down cycles after one interface timer change. Which check provides the most useful information for fixing this deployment?

  1. Inspect VRRP advertisements gateway owner and virtual MAC state.
  2. Inspect IPv6 link-local neighbors OSPFv3 interface area and router ID.
  3. Inspect active equal-cost routes flow hashing and actual per-link counters.
  4. Inspect received hello timers and neighbor reset reasons.

Explanation

Correct Answer

D:

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. Inspect received hello timers and neighbor reset reasons is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

B:

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, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

C:

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, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

Question 1131

At West Auditorium, a newly deployed tri-band AP power-limits features when its access-switch closet is near budget. What should be examined to confirm the actual failure mechanism?

  1. Examine serial record device assignment onboarding logs DNS and outbound management connectivity.
  2. Examine advertised versus delivered power and AP reduced-function power mode.
  3. Examine AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  4. Examine route table source interface and ACLs in the actual management VRF.

Explanation

Correct Answer

B:

For West Auditorium, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Inspect advertised versus delivered power and AP reduced-function power mode 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 West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

C:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

D:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

Question 1132

At Garden Hall, a warehouse controller added a partially overlapping 2.4-GHz channel near channel 6. What safety boundary prevents the same campus failure in future deployments?

  1. Retain guest clients isolated from internal networks throughout portal state changes.
  2. Retain rollout headroom and test gateway interoperability during upgrades.
  3. Follow regulatory channel availability and avoid indiscriminate band use.
  4. Avoid compensating for poor placement only by increasing transmit power.

Explanation

Correct Answer

C:

For Garden Hall, the decisive mechanism is Adjacent-channel overlap. Adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing. Follow regulatory channel availability and avoid indiscriminate band use is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing

Question 1133

At Lakeside Classroom, a visitor completes a portal login yet remains in a restricted pre-authentication role. What should be examined to confirm the actual failure mechanism?

The specific mechanism is captive portal authentication and post-login role enforcement are separate controls

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is captive portal authentication and post-login role enforcement are separate controls

D:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Lakeside Classroom case, Those observations could be normal while the stated fault persists. The specific mechanism is captive portal authentication and post-login role enforcement are separate controls

Question 1134

At West Clinic, a new 6-GHz SSID is absent from older client devices in a mixed fleet. What should the engineer implement first to correct the stated condition?

  1. Set up guest authentication flow and role transitions with appropriate enforcement.
