Question 240

At Lakeside Classroom, a topology change moves the root toward a low-bandwidth edge switch. What measured or witnessed result should be required before signoff?

  1. Check a client retains default-gateway reachability across a member failure.
  2. Simulate one access uplink failure and confirm expected VSX LAG forwarding persists.
  3. Simulate controlled ISL loss and verify the documented split-brain prevention behavior.
  4. Fail an uplink and verify deterministic rapid reconvergence without unexpected blocking.

Explanation

Correct Answer

D:

For Lakeside Classroom, the decisive mechanism is RSTP root placement. RSTP uses a root bridge and port roles to build a loop-free Layer 2 topology. Fail an uplink and verify deterministic rapid reconvergence without unexpected blocking 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 Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

B:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

C:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Lakeside Classroom case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

Question 241

At Learning Commons, an access controller sends requests from an address omitted from ClearPass NAD definitions. What measured or witnessed result should be required before signoff?

  1. Reach the approved server from the intended management interface without leaking access VLANs.
  2. Check the effective deployed settings match the intended group policy on a pilot device.
  3. See an Access-Accept or deliberate Reject for the right request with recorded server logs.
  4. Show the right device online under the approved group and site without exposing another tenant.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is RADIUS server connectivity. NAD identity and transport reachability must be correct before policy results matter. See an Access-Accept or deliberate Reject for the right request with recorded server logs supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is nAD identity and transport reachability must be correct before policy results matter

B:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is nAD identity and transport reachability must be correct before policy results matter

D:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Learning Commons case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is nAD identity and transport reachability must be correct before policy results matter

Question 242

At Research Hub, a device with a static address fails ARP validation after a DHCP-snooping policy upgrade. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine interface VLAN mode learned MAC address and DHCP lease subnet.
  2. Cross-check allowed VLAN list tagging and egress counters at both ends.
  3. Examine neighbor LLDP-MED TLVs and phone versus PC VLAN tags.
  4. Examine ARP drops source MAC/IP and snooping binding entries.

Explanation

Correct Answer

D:

For Research Hub, the decisive mechanism is ARP inspection dependency. Dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing. Inspect ARP drops source MAC/IP and snooping binding entries is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

B:

This is relevant to Tagged trunk allowlist, where a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

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 Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic ARP inspection relies on credible address-to-MAC bindings to reject spoofing

Question 243

At North Residence, a campus core VSX design uses an undersized ISL and traffic fails during one access uplink outage. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  2. Set up supported VRRP virtual gateway ownership and priority on matched interfaces.
  3. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  4. Activate supported loop protection on suitable edge ports and keep STP defenses active.

Explanation

Correct Answer

C:

For North Residence, the decisive mechanism is VSX inter-switch link. VSX peers synchronize selected state over an ISL while retaining independent control planes. Build a supported VSX ISL with enough capacity and verify peer state consistency establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

B:

This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

D:

This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the North Residence case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vSX peers synchronize selected state over an ISL while retaining independent control planes

Question 244

At Central Hall, an access switch aggregates two fiber uplinks but both links remain independently forwarding. Which controlled configuration is most likely to restore the required service?

  1. Set compatible LACP mode and LAG identifiers on peers and attach agreed member interfaces.
  2. Align MTU and encapsulation requirements across the complete supported forwarding path.
  3. Advertise approved LLDP-MED voice VLAN and separate PC data access classification.
  4. Apply the appropriate permit/deny order and direction on the data-path interface.

Explanation

Correct Answer

A:

For Central Hall, the decisive mechanism is Dynamic LACP bundle. LACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient. Set compatible LACP mode and LAG identifiers on peers and attach agreed member interfaces establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

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 Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

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 Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

D:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

Question 245

At Technology Center, a branch has two default routes but prefers the backup due to unexpected distance. Which practical change is best suited to this topology and its constraints?

  1. Restore an authorized default next hop and deliberate route preferences.
  2. Ensure relay source and server return routing permit both directions of the DHCP exchange.
  3. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.
  4. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.

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. Restore an authorized default next hop and deliberate route preferences establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

C:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

D:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

Question 246

At Convention Center, a warehouse AP behind metal shelving creates signal shadowing at scanner height. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Evaluate supported multicast conversion and membership control for the audience size.
  2. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  3. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.
  4. Reposition supported antennas and APs according to an active coverage survey.

Explanation

Correct Answer

D:

For Convention Center, the decisive mechanism is Antenna orientation and placement. Antenna radiation pattern and placement govern usable RF cell shape. Reposition supported antennas and APs according to an active coverage survey establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is antenna radiation pattern and placement govern usable RF cell shape

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is antenna radiation pattern and placement govern usable RF cell shape

C:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is antenna radiation pattern and placement govern usable RF cell shape

Question 247

At Riverside Building, a branch has the correct OSPF route but packets stop at the distribution firewall. Which practical change is best suited to this topology and its constraints?

  1. Trace the forward and reverse forwarding path including route recursion and ACLs.
  2. Trace VLAN classification DHCP relay/server route and lease scope in sequence.
  3. Review the specific ClearPass service match authentication source and TLS decision.
  4. Examine optics cabling transceiver support and duplex/speed at both ends before changing routes.

Explanation

Correct Answer

A:

For Riverside Building, the decisive mechanism is Routed blackhole. Route presence alone does not prove usable bidirectional forwarding. Trace the forward and reverse forwarding path including route recursion and ACLs establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

D:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

Question 248

At Administration Block, the NOC cannot tell whether an outage affects SaaS or only on-campus DNS names. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Secure sensitive mirrored payloads and remove temporary sessions after testing.
  2. Position sensors where representative users connect and manage test credentials safely.
  3. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.
  4. Set up complementary UXI internal service and external Internet tests.

Explanation

Correct Answers

B:

This is the continuing risk-control element for Administration Block. Position sensors where representative users connect and manage test credentials safely 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 Administration Block case: Internal and external synthetic tests isolate distinct service paths and failure domains. The specific action Configure complementary UXI internal service and external Internet tests addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

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

C:

This may be a configuration step for NAE monitor rule: NAE agents monitor local switch state and can correlate rule conditions over time. It does not resolve the UXI internal and external tests requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is internal and external synthetic tests isolate distinct service paths and failure domains

Question 249

At Research Hub, a campus gateway never receives employee SSID packets because the WLAN is set to bridge locally. What should the engineer implement first to correct the stated condition?

  1. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  2. Bind the device to its approved group and review group-level settings and local overrides.
  3. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster.
  4. Add an authorized management-VRF route and correct source reachability for the target service.

Explanation

Correct Answer

C:

For Research Hub, the decisive mechanism is Bridge versus tunneled WLAN traffic. Bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

B:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

D:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

Question 250

At Technology Center, a handheld scans an AP yet fails to join after an advertised WLAN capability change. What safety boundary prevents the same campus failure in future deployments?

  1. Change WLAN capability requirements in a tested pilot rather than disabling security campus-wide.
  2. Preserve reserve PoE capacity and recheck the budget during AP model changes.
  3. Restrict sensitive management details on ports where topology advertisement is inappropriate.
  4. Preserve approved transceiver and link-setting baselines for any future port migration.

Explanation

Correct Answer

A:

For Technology Center, the decisive mechanism is 802.11 association sequence. 802.11 discovery and association occur before user traffic can be successfully forwarded. Change WLAN capability requirements in a tested pilot rather than disabling security campus-wide is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

C:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

D:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Technology Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded
