Question 1000

At West Auditorium, a client on VLAN 145 cannot obtain a lease because the DHCP server is in a routed services VRF. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Maintain helper inventories and validate server reachability before subnet migrations.
  2. Configure the VLAN interface DHCP relay toward an authorized reachable server and return route.
  3. Set the AP switchport VLAN tagging PoE and DHCP reachability according to the deployment mode.
  4. Assess roaming and segmentation impacts before changing WLAN forwarding mode.

Explanation

Correct Answers

A:

This is the continuing risk-control element for West Auditorium. Maintain helper inventories and validate server reachability before subnet migrations prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

B:

This is the implementation element for the West Auditorium case: DHCP relay forwards client requests across routed boundaries; switching alone does not. The specific action Configure the VLAN interface DHCP relay toward an authorized reachable server and return route addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

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 Campus DHCP relay requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is dHCP relay forwards client requests across routed boundaries; switching alone does not

D:

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 Campus DHCP relay requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is dHCP relay forwards client requests across routed boundaries; switching alone does not

Question 1001

At Convention Center, a staff pilot changes a personal SSID to WPA3-SAE and older tablets fail to connect. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  2. Use an RF plan with reasonable channel reuse and channel width for expected density.
  3. Perform an active site survey covering attenuation interference and realistic client density.
  4. Select supported SAE or a controlled transition approach based on known client support.

Explanation

Correct Answer

D:

For Convention Center, the decisive mechanism is WPA3 SAE personal WLAN. SAE changes personal WLAN authentication compared with WPA2-PSK. Select supported SAE or a controlled transition approach based on known client support establishes the needed configuration in the case rather than merely measuring a symptom.

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

B:

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, Changing that neighboring feature does not implement the missing function. 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, Changing that neighboring feature does not implement the missing function. The specific mechanism is sAE changes personal WLAN authentication compared with WPA2-PSK

Question 1002

At Learning Commons, an iBGP reflector advertises a prefix but receivers lack IGP reachability to its next hop. Which check provides the most useful information for fixing this deployment?

  1. Examine received hello timers and neighbor reset reasons.
  2. Examine BGP best-path next-hop recursion and routing table.
  3. Examine OSPF hello packet area values network type and adjacency state.
  4. Cross-check default prefixes distances next-hop health and forwarding decisions.

Explanation

Correct Answer

B:

For Learning Commons, the decisive mechanism is BGP next-hop resolution. A BGP advertisement may be valid but unusable without next-hop reachability. Inspect BGP best-path next-hop recursion and routing table is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Learning Commons case, Those observations could be normal while the stated fault persists. The specific mechanism is a BGP advertisement may be valid but unusable without next-hop reachability

C:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Learning Commons case, Those observations could be normal while the stated fault persists. The specific mechanism is a BGP advertisement may be valid but unusable without next-hop reachability

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 Learning Commons case, Those observations could be normal while the stated fault persists. The specific mechanism is a BGP advertisement may be valid but unusable without next-hop reachability

Question 1003

At Bayside Campus, the policy team cannot trace which staff device used a port during an incident. Which practical change is best suited to this topology and its constraints?

  1. Enable supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  2. Enable appropriate RADIUS start/interim/stop accounting to the approved server.
  3. Return supported VLAN or role attributes that match network enforcement configuration.
  4. Configure appropriate RADIUS failover and tested timeout/retry settings.

Explanation

Correct Answer

B:

For Bayside Campus, the decisive mechanism is RADIUS accounting for audit. AAA accounting tracks session use separately from authentication and authorization. Enable appropriate RADIUS start/interim/stop accounting to the approved server establishes the needed configuration in the case rather than merely measuring a symptom.

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

C:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

D:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is aAA accounting tracks session use separately from authentication and authorization

Question 1004

At Central Hall, an access switch aggregates two fiber uplinks but both links remain independently forwarding. Which controlled acceptance test demonstrates the required behavior?

  1. Verify both members are selected and eligible under normal operation.
  2. Permit a specifically authorized app and block the matching forbidden traffic.
  3. Run controlled large-payload tests and confirm reliable path MTU behavior.
  4. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.

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. Verify both members are selected and eligible under normal operation supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

C:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

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 Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

Question 1005

At Central Hall, a laptop passes 802.1X but receives a 169.254 address instead of the expected VLAN lease. Which test best differentiates real success from a merely healthy status light?

  1. Verify the user reaches only the assigned subnet and policy resources.
  2. Prove permitted bidirectional application traffic reaches the endpoint.
  3. Simulate uplink failure and verify expected rapid convergence without loops.
  4. Obtain the expected lease plus gateway and DNS with valid test credentials.

Explanation

Correct Answer

D:

For Central Hall, the decisive mechanism is DHCP address-acquisition failure. Network authorization and DHCP allocation are separate stages requiring their own diagnostics. Obtain the expected lease plus gateway and DNS with valid test credentials supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

Question 1006

At Main Data Center, a port is up yet users report packet loss and CRC errors during large transfers. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Configure User Experience Insight sensor tests that reflect actual user networks and destinations.
  2. Collect interface error discard and utilization counters with suitable baseline intervals.
  3. Configure a supported mirror session with explicit source direction and valid destination port.
  4. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.

Explanation

Correct Answer

B:

For Main Data Center, the decisive mechanism is Switch telemetry counters. Interface counters help distinguish physical corruption from congestion drops. Collect interface error discard and utilization counters with suitable baseline intervals establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to UXI client experience probes, where uXI sensors run synthetic end-user workflows to reveal service-layer failures In the Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is interface counters help distinguish physical corruption from congestion drops

C:

This is relevant to Port mirroring PCAP, where port mirroring copies selected frames for observation but is not a live forwarding path In the Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is interface counters help distinguish physical corruption from congestion drops

D:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the Main Data Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is interface counters help distinguish physical corruption from congestion drops

Question 1007

At Convention Center, a shared accommodation WLAN gateway leaks inter-client traffic on a common broadcast domain. Which controlled acceptance test demonstrates the required behavior?

  1. Check untagged test frames land in the same approved VLAN at both endpoints.
  2. Prove guest-to-guest connections fail while Internet access continues.
  3. See device traffic only in its assigned broadcast domain and expected address scope.
  4. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.

Explanation

Correct Answer

B:

For Convention Center, the decisive mechanism is Private client isolation. Client isolation can block same-segment lateral traffic without relying on routing ACLs. Prove guest-to-guest connections fail while Internet access continues supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is client isolation can block same-segment lateral traffic without relying on routing ACLs

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is client isolation can block same-segment lateral traffic without relying on routing ACLs

D:

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 Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is client isolation can block same-segment lateral traffic without relying on routing ACLs

Question 1008

At South Science Wing, a new AP was patched to an access port without its management VLAN. What measured or witnessed result should be required before signoff?

  1. See the AP obtain correct management addressing and report online in Central.
  2. Reach the approved server from the intended management interface without leaking access VLANs.
  3. Show the right device online under the approved group and site without exposing another tenant.
  4. Confirm the effective deployed settings match the intended group policy on a pilot device.

Explanation

Correct Answer

A:

For South Science Wing, the decisive mechanism is AP uplink physical mapping. AP service onboarding depends on both physical power and the upstream management network. See the AP obtain correct management addressing and report online in Central supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

C:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

D:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

Question 1009

At Central Hall, a new campus fiber uplink should be preferred but interface costs retain old values. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Retain symmetric return routing in mind when changing one direction's cost.
  2. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  3. Test preemption and split-brain behavior during a controlled pilot.
  4. Establish intentional OSPF interface cost reflecting primary and backup path design.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Central Hall. Keep symmetric return routing in mind when changing one direction's cost 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 Central Hall case: OSPF chooses shortest paths based on cumulative advertised link cost. The specific action Set intentional OSPF interface cost reflecting primary and backup path design addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be a configuration step for IPv6 OSPFv3 adjacency: OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. It does not resolve the OSPF metric selection requirement in Central Hall and is not one of the two controls requested. The direct mechanism here is oSPF chooses shortest paths based on cumulative advertised link cost

C:

This may be an ongoing precaution for First-hop gateway election: VRRP abstracts the default gateway across eligible routing devices. It does not resolve the OSPF metric selection requirement in Central Hall and is not one of the two controls requested. The direct mechanism here is oSPF chooses shortest paths based on cumulative advertised link cost

Question 1010

At Convention Center, an access network changes authentication timeout settings but client EAP exchanges exceed them. Which configuration change best fits the network requirement and observed behavior?

  1. Activate supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  2. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  3. Set up appropriate RADIUS failover and tested timeout/retry settings.
  4. Return supported VLAN or role attributes that match network enforcement configuration.

Explanation

Correct Answer

B:

For Convention Center, the decisive mechanism is Supplicant reauthentication intervals. Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. Tune supported reauthentication and EAP timers based on measured client/server behavior establishes the needed configuration in the case rather than merely measuring a symptom.

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

D:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate
