Question 790

At Riverside Building, two cables connect an access stack to aggregation but only one LACP member forwards. Which controlled configuration is most likely to restore the required service?

  1. Configure compatible LACP membership and logical LAG settings across the supported endpoints.
  2. Bind the device to its approved group and review group-level settings and local overrides.
  3. Verify subscription device identity Central assignment and management reachability in the authorized tenant.
  4. Add an authorized management-VRF route and correct source reachability for the target service.

Explanation

Correct Answer

A:

For Riverside Building, the decisive mechanism is LACP uplink provisioning. LACP forms one logical bundle only when peers agree on aggregation parameters. Configure compatible LACP membership and logical LAG settings across the supported endpoints establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

C:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

D:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP forms one logical bundle only when peers agree on aggregation parameters

Question 791

At Transit Operations Center, an existing gateway SVI has the wrong prefix and staff clients cannot reach routed services. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine serial record device assignment onboarding logs DNS and outbound management connectivity.
  2. Examine AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  3. Examine SVI up state VLAN membership ARP and routing table for the gateway subnet.
  4. Trace where client frames exit the AP versus enter the Aruba gateway datapath.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is SVI gateway provisioning. An SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch. Inspect SVI up state VLAN membership ARP and routing table for the gateway subnet 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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch

D:

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI connects a VLAN broadcast domain to Layer 3 routing on a capable switch

Question 792

At Transit Operations Center, a lab switch becomes root after a new access switch with a lower bridge ID is added. What should be examined to confirm the actual failure mechanism?

  1. Inspect frame-size drop counters PMTU behavior and VLAN/tunnel overhead.
  2. Inspect hit counters rule ordering and packet direction for a controlled flow.
  3. Inspect the elected root and root-port path cost before changing cabling.
  4. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is STP root optimization. Spanning Tree selects the root by bridge ID and derives loop-free port roles. Inspect the elected root and root-port path cost before changing cabling is the most direct way to isolate this particular failure before making a change.

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is spanning Tree selects the root by bridge ID and derives loop-free port roles

B:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is spanning Tree selects the root by bridge ID and derives loop-free port roles

D:

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is spanning Tree selects the root by bridge ID and derives loop-free port roles

  1. Enforce role or group-based segmentation at the supported switching/gateway point.
  2. Choose supported WPA3-Enterprise settings and validated client capability before rollout.
  3. Set up supported RADIUS accounting and consistent session identifier delivery.
  4. Coordinate valid certificate chain rotation and trust propagation before expiry.

Explanation

Correct Answer

B:

For Innovation Studio, the decisive mechanism is WPA3 Enterprise compatibility. WPA3-Enterprise builds on supported enterprise security capabilities with stronger protections. Choose supported WPA3-Enterprise settings and validated client capability before rollout establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

D:

Question 794

At Garden Hall, a wired workstation reports an EAPOL authentication timeout before it can request a DHCP address. Which observation most directly isolates the likely cause before any change?

  1. Inspect switch PoE allocation operational draw power-denial and AP boot-event evidence.
  2. Inspect EAPOL start identity exchange RADIUS decision and authenticated port status.
  3. Compare operational speed duplex FCS errors and auto-negotiation on each side of the link.
  4. Inspect local and remote LLDP chassis port and management addresses against physical patch records.

Explanation

Correct Answer

B:

For Garden Hall, the decisive mechanism is 802.1X EAPOL versus IP service. 802.1X is port-based access control; IP configuration occurs after network admission. Inspect EAPOL start identity exchange RADIUS decision and authenticated port status is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

C:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

D:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

Question 795

At West Clinic, a campus transit VLAN is vulnerable to untrusted routing peers unless OSPF authentication is enforced. Which test best differentiates real success from a merely healthy status light?

  1. Generate many independent test flows and compare distribution without requiring per-packet balance.
  2. Check authorized peers reach Full while mismatched lab peers fail.
  3. Fail one gateway and confirm uninterrupted client default-route access within design targets.
  4. Check appropriate IPv6 routes are learned and prefixes stay reachable.

Explanation

Correct Answer

B:

For West Clinic, the decisive mechanism is OSPF neighbor authentication. OSPF authentication protects adjacency formation against unauthorized peers. Confirm authorized peers reach Full while mismatched lab peers fail supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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 West Clinic case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

C:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the West Clinic case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

D:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the West Clinic case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF authentication protects adjacency formation against unauthorized peers

Question 796

At West Clinic, a newly racked campus switch has Internet access but never appears in the intended Aruba Central site. What recurring protection should accompany this configuration?

  1. Use controlled serial-number ownership checks and avoid blindly claiming unknown devices.
  2. Assess roaming and segmentation impacts before changing WLAN forwarding mode.
  3. Prevent independent links from creating a Layer 2 loop during LAG migrations.
  4. Treat AP port changes as staged network access changes rather than bypassing admission.

Explanation

Correct Answer

A:

For West Clinic, the decisive mechanism is Central device onboarding. Cloud inventory association and device management connectivity are separate onboarding requirements. Use controlled serial-number ownership checks and avoid blindly claiming unknown devices is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

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 West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

C:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

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 West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud inventory association and device management connectivity are separate onboarding requirements

Question 797

At Convention Center, a shared accommodation WLAN gateway leaks inter-client traffic on a common broadcast domain. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Apply supported client isolation or per-user role policy at the correct enforcement point.
  2. Never expand a trunk to all VLANs merely to resolve one missing segment.
  3. Establish the switchport as an access member of the correct VLAN with matching policy.
  4. Do not use one flat VLAN as a substitute for isolation and policy.

Explanation

Correct Answers

A:

This is the implementation element for the Convention Center case: Client isolation can block same-segment lateral traffic without relying on routing ACLs. The specific action Apply supported client isolation or per-user role policy at the correct enforcement point addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Convention Center. Do not use one flat VLAN as a substitute for isolation and policy prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

B:

This may be an ongoing precaution for Tagged trunk allowlist: A VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration. It does not resolve the Private client isolation requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is client isolation can block same-segment lateral traffic without relying on routing ACLs

C:

This may be a configuration step for Access VLAN classification: An access port carries untagged frames in one configured access VLAN. It does not resolve the Private client isolation requirement in Convention Center and is not one of the two controls requested. The direct mechanism here is client isolation can block same-segment lateral traffic without relying on routing ACLs

Question 798

At Bayside Campus, an access switch discards packets during microbursts despite modest one-minute interface utilization. Which check provides the most useful information for fixing this deployment?

  1. Inspect roaming client RSSI overlap and channel utilization across cells.
  2. Inspect group subscriptions multicast airtime and converted frame counts.
  3. Inspect per-queue discard and buffer occupancy around the exact burst.
  4. Inspect associated bands steering outcomes and per-band utilization.

Explanation

Correct Answer

C:

For Bayside Campus, the decisive mechanism is Congestion buffer drops. Short congestion bursts can exhaust queues before low-frequency monitoring notices. Inspect per-queue discard and buffer occupancy around the exact burst is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

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 Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

D:

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 Bayside Campus case, Those observations could be normal while the stated fault persists. The specific mechanism is short congestion bursts can exhaust queues before low-frequency monitoring notices

Question 799

At West Auditorium, a dense enterprise WLAN needs advisory roam guidance without hard-disconnecting phones. Which controlled configuration is most likely to restore the required service?

  1. Set up guest authentication flow and role transitions with appropriate enforcement.
  2. Adjust mounting antenna orientation and power using active RF measurements.
  3. Apply supported clustered gateway configuration with capacity and software-version compatibility.
  4. Activate appropriate 802.11v BSS transition management and monitor client support.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is 802.11v BSS transition. 802.11v can suggest a transition; the client retains a role in the roaming decision. Enable appropriate 802.11v BSS transition management and monitor client support establishes the needed configuration in the case rather than merely measuring a symptom.

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 West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

B:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

C:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the West Auditorium case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11v can suggest a transition; the client retains a role in the roaming decision

Question 800

At North Library, a test client sends DHCP packets but the engineer sees none on an external capture laptop. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Configure a supported mirror session with explicit source direction and valid destination port.
  2. Protect sensitive mirrored payloads and remove temporary sessions after testing.
  3. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.
  4. Configure complementary UXI internal service and external Internet tests.

Explanation

Correct Answers

A:

This is the implementation element for the North Library case: Port mirroring copies selected frames for observation but is not a live forwarding path. The specific action Configure a supported mirror session with explicit source direction and valid destination port addresses the stated fault; the question also requires a persistent risk control.

B:

This is the continuing risk-control element for North Library. Protect sensitive mirrored payloads and remove temporary sessions after testing prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

C:

This may be an ongoing precaution for Switch telemetry counters: Interface counters help distinguish physical corruption from congestion drops. It does not resolve the Port mirroring PCAP requirement in North Library and is not one of the two controls requested. The direct mechanism here is port mirroring copies selected frames for observation but is not a live forwarding path

D:

This may be a configuration step for UXI internal and external tests: Internal and external synthetic tests isolate distinct service paths and failure domains. It does not resolve the Port mirroring PCAP requirement in North Library and is not one of the two controls requested. The direct mechanism here is port mirroring copies selected frames for observation but is not a live forwarding path
