Question 200

At Hillcrest Campus, an AP 6 GHz radio never activates while PoE is negotiated at a low class. Which controlled configuration is most likely to restore the required service?

  1. Verify subscription device identity Central assignment and management reachability in the authorized tenant.
  2. Supply supported PoE class and verify available per-port and total chassis power budget.
  3. Add an authorized management-VRF route and correct source reachability for the target service.
  4. Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.

Explanation

Correct Answer

B:

For Hillcrest Campus, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Supply supported PoE class and verify available per-port and total chassis power budget establishes the needed configuration in the case rather than merely measuring a symptom.

D:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the Hillcrest Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

Question 201

At Hillcrest Campus, a tagged access uplink forwards a newly added IoT VLAN into an unapproved trunk VLAN. What observable outcome would prove this repair actually works?

  1. Replace the suspect physical component and verify error rates stabilize under traffic.
  2. Correct the applicable rule and see authorized identity succeed while unknown clients fail.
  3. Demonstrate the user reaches only the assigned subnet and policy resources.
  4. Obtain the expected lease plus gateway and DNS with valid test credentials.

Explanation

Correct Answer

C:

For Hillcrest Campus, the decisive mechanism is Wrong VLAN mapping. WLAN-to-wired mapping errors can appear as a DHCP or authorization defect. Verify the user reaches only the assigned subnet and policy resources supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wLAN-to-wired mapping errors can appear as a DHCP or authorization defect

B:

This is relevant to RADIUS Access-Reject root cause, where an explicit RADIUS reject can come from credential validation or authorization policy In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails.

Question 202

At Technology Center, two gateway peers advertise inconsistent VRRP virtual IP settings after maintenance. Which observation most directly isolates the likely cause before any change?

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

Explanation

Correct Answer

C:

For Technology Center, 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 inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Technology Center 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 Technology Center 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

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center case, Those observations could be normal while the stated fault persists.

Question 203

At Central Hall, a guest team tries to enable 6-GHz on an AP model without a matching radio capability. What safety boundary prevents the same campus failure in future deployments?

  1. Keep guest clients isolated from internal networks throughout portal state changes.
  2. Retain rollout headroom and test gateway interoperability during upgrades.
  3. Do not assume all 5-GHz-capable clients support 6-GHz discovery or security.
  4. Avoid compensating for poor placement only by increasing transmit power.

Explanation

Correct Answer

C:

For Central Hall, the decisive mechanism is 6-GHz WLAN eligibility. 6-GHz operation requires compatible radios security and jurisdiction-specific channels. Do not assume all 5-GHz-capable clients support 6-GHz discovery or security 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 Central Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Central Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

D:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 6-GHz operation requires compatible radios security and jurisdiction-specific channels

Question 204

At Learning Commons, a new downstream switch advertises a superior root and changes STP path selection unexpectedly. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Trace VLAN classification DHCP relay/server route and lease scope in sequence.
  2. Examine optics cabling transceiver support and duplex/speed at both ends before changing routes.
  3. Review the specific ClearPass service match authentication source and TLS decision.
  4. Correct STP root priorities and protect edge or downstream boundaries as appropriate.

Explanation

Correct Answer

D:

For Learning Commons, the decisive mechanism is STP convergence fault. STP role and root election determine the alternate Layer 2 forwarding path. Correct STP root priorities and protect edge or downstream boundaries as appropriate establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is sTP role and root election determine the alternate Layer 2 forwarding path

B:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is sTP role and root election determine the alternate Layer 2 forwarding path

C:

This is relevant to RADIUS Access-Reject root cause, where an explicit RADIUS reject can come from credential validation or authorization policy In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is sTP role and root election determine the alternate Layer 2 forwarding path

Question 205

At Athletics Complex, an AOS-CX switch pings the Internet in default VRF but cannot reach its management NTP server. What should be examined to confirm the actual failure mechanism?

  1. Inspect LACP actor partner keys synchronization and individual member states.
  2. Inspect AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  3. Trace where client frames exit the AP versus enter the Aruba gateway datapath.
  4. Inspect route table source interface and ACLs in the actual management VRF.

Explanation

Correct Answer

D:

For Athletics Complex, the decisive mechanism is Management VRF reachability. AOS-CX management VRF and default forwarding VRF may have separate reachability. Inspect route table source interface and ACLs in the actual management VRF is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

B:

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

C:

This is relevant to Bridge versus tunneled WLAN traffic, where bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy In the Athletics Complex case, Those observations could be normal while the stated fault persists. The specific mechanism is aOS-CX management VRF and default forwarding VRF may have separate reachability

Question 206

At Convention Center, a staff pilot changes a personal SSID to WPA3-SAE and older tablets fail to connect. How should the engineer validate success against the stated requirement?

  1. Measure improved SNR and reduced retry rate without oversizing transmit power.
  2. Connect modern clients securely and document any explicitly retained legacy devices.
  3. Confirm coverage and capacity with representative real devices and occupancy.
  4. Observe lower airtime contention and stable throughput during concurrent client use.

Explanation

Correct Answer

B:

For Convention Center, the decisive mechanism is WPA3 SAE personal WLAN. SAE changes personal WLAN authentication compared with WPA2-PSK. Connect modern clients securely and document any explicitly retained legacy devices supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

C:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

D:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

Question 207

At Technology Center, contractors successfully authenticate but receive full staff network permissions. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Coordinate valid certificate chain rotation and trust propagation before expiry.
  2. Return and enforce the correct identity-based role or VLAN through ClearPass and access infrastructure.
  3. Enforce role or group-based segmentation at the supported switching/gateway point.
  4. Configure supported RADIUS accounting and consistent session identifier delivery.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is ClearPass role-based enforcement. ClearPass decides authorization outcomes while network devices enforce assigned policy. Return and enforce the correct identity-based role or VLAN through ClearPass and access infrastructure establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

D:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

Question 208

At South Science Wing, a high-volume single flow saturates one uplink although both ECMP next hops are installed. Which check provides the most useful information for fixing this deployment?

  1. Examine OSPF hello packet area values network type and adjacency state.
  2. Examine DBD neighbor events DR election and interface OSPF mode.
  3. Examine active equal-cost routes flow hashing and actual per-link counters.
  4. Examine received hello timers and neighbor reset reasons.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is ECMP next-hop selection. ECMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet. Inspect active equal-cost routes flow hashing and actual per-link counters is the most direct way to isolate this particular failure before making a change.

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 South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

B:

This is relevant to OSPF network type, where oSPF network type affects hello behavior and DR election on multiaccess segments In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

D:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet

Question 209

At North Residence, a phone and PC share one Ethernet port yet the switch applies one role to both clients. Which change-management constraint best guards against recurrence?

  1. Preserve intentional restricted access for unmanaged endpoint classes.
  2. Version enforcement profiles and test against the deployed switch software.
  3. Do not broadly fail-open protected ports on temporary RADIUS loss.
  4. Restrict the number of clients per port and reject unrecognized daisy-chain devices.

Explanation

Correct Answer

D:

For North Residence, the decisive mechanism is Phone and PC multi-domain. Multi-domain wired access can maintain distinct voice and user authorization sessions. Restrict the number of clients per port and reject unrecognized daisy-chain devices is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions

B:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the North Residence case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions
