Question 730

At Athletics Complex, a phone is consistently rejected because ClearPass assigns it to an unexpected policy branch. Which ongoing safeguard best limits the specific risk after rollout?

  1. Retain a source-controlled VLAN matrix for AP groups and switch closets.
  2. Retain rollback access during global STP region or root changes.
  3. Apply staged routing changes and monitor policy symmetry.
  4. Do not broaden all enforcement results when one service policy is wrong.

Explanation

Correct Answer

D:

For Athletics Complex, the decisive mechanism is RADIUS Access-Reject root cause. An explicit RADIUS reject can come from credential validation or authorization policy. Do not broaden all enforcement results when one service policy is wrong is an enduring limitation on the operational risk, not simply a one-time passing test.

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 Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

B:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

C:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Athletics Complex case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

Question 731

At Arts Pavilion, a softphone deployment experiences choppy audio over congested Wi-Fi while speed tests look good. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Avoid creating unlimited high-priority traffic by trusting any client marker.
  2. Evaluate supported multicast conversion and membership control for the audience size.
  3. Allow documented compatibility cases instead of forcing a universal band cutoff.
  4. Prioritize authenticated voice appropriately and reduce contention on affected paths.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Arts Pavilion. Avoid creating unlimited high-priority traffic by trusting any client marker 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 Arts Pavilion case: Real-time voice quality depends on delay variation and loss more than raw peak throughput. The specific action Prioritize authenticated voice appropriately and reduce contention on affected paths addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be a configuration step for Multicast-to-unicast tradeoff: Multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work. It does not resolve the Voice jitter and packet loss requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is real-time voice quality depends on delay variation and loss more than raw peak throughput

C:

This may be an ongoing precaution for Band steering under load: Band steering can guide dual-band association but depends on real RF and client support. It does not resolve the Voice jitter and packet loss requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is real-time voice quality depends on delay variation and loss more than raw peak throughput

Question 732

At Medical Annex, a new neighbor fails to form because mismatched hello/dead intervals are configured. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.
  3. Apply supported ECMP and account for session hash distribution across eligible paths.
  4. Establish compatible OSPF interface hello and dead intervals on both peers.

Explanation

Correct Answer

D:

For Medical Annex, the decisive mechanism is OSPF hello and dead timers. OSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists. Set compatible OSPF interface hello and dead intervals on both peers establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Medical Annex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Medical Annex case, Changing that neighboring feature does not implement the missing function. 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 Medical Annex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

Question 733

At Riverside Building, a student sets up a personal hotspot DHCP server connected to the campus access switch. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Set the switchport as an access member of the correct VLAN with matching policy.
  2. Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs.
  3. Guard against arbitrary untrusted client VLAN tagging on shared ports.
  4. Document trusted uplink changes and review replacement switch ports.

Explanation

Correct Answers

B:

This is the implementation element for the Riverside Building case: DHCP snooping prevents DHCP-server responses from untrusted ports. The specific action Trust only authorized DHCP-server facing ports and enable snooping on the relevant VLANs addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Riverside Building. Document trusted uplink changes and review replacement switch ports prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

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 DHCP snooping trust boundary requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is dHCP snooping prevents DHCP-server responses from untrusted ports

C:

This may be an ongoing precaution for Voice VLAN LLDP-MED: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. It does not resolve the DHCP snooping trust boundary requirement in Riverside Building and is not one of the two controls requested. The direct mechanism here is dHCP snooping prevents DHCP-server responses from untrusted ports

Question 734

At Innovation Studio, a campus migration introduces gateway versions with incompatible feature behavior. What recurring protection should accompany this configuration?

  1. Avoid excessive AP transmit power that creates broad overlapping cells.
  2. Repeat surveys after major layout or material changes rather than trusting only plans.
  3. Retain rollout headroom and test gateway interoperability during upgrades.
  4. Track both RF signal and noise as part of acceptance tests.

Explanation

Correct Answer

C:

For Innovation Studio, the decisive mechanism is Gateway cluster resiliency. Tunneled service resilience requires usable gateway capacity and working AP tunnels. Retain rollout headroom and test gateway interoperability during upgrades is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

B:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

D:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is tunneled service resilience requires usable gateway capacity and working AP tunnels

Question 735

At South Science Wing, two tenants have overlapping 10.10.0.0/16 networks but must use the same campus core. Which configuration change best fits the network requirement and observed behavior?

  1. Restore an authorized default next hop and deliberate route preferences.
  2. Install a valid static route with a resolvable next hop and appropriate administrative distance.
  3. Align OSPF area ID and supported area type at both neighboring interfaces.
  4. Use supported VRFs and explicit approved import/export or transit policy for any crossing.

Explanation

Correct Answer

D:

For South Science Wing, the decisive mechanism is VRF segmentation routing. VRFs maintain separate forwarding and routing instances on supported devices. Use supported VRFs and explicit approved import/export or transit policy for any crossing establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

B:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the South Science Wing case, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

C:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

Question 736

At West Auditorium, wireless clients associate to a tunnel SSID but no user traffic reaches the services gateway. Which ongoing safeguard best limits the specific risk after rollout?

  1. Use staged routing changes and monitor policy symmetry.
  2. Keep distinct troubleshooting for management access and user-plane transport.
  3. Retain spare supported optics and baseline error counters before maintenance.
  4. Keep a source-controlled VLAN matrix for AP groups and switch closets.

Explanation

Correct Answer

B:

For West Auditorium, the decisive mechanism is AP gateway tunnel fault. Cloud management connectivity does not imply a healthy user tunnel. Keep distinct troubleshooting for management access and user-plane transport is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the West Auditorium case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

C:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the West Auditorium case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

D:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the West Auditorium case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

Question 737

At Medical Annex, a new neighbor fails to form because mismatched hello/dead intervals are configured. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Test preemption and split-brain behavior during a controlled pilot.
  3. Establish compatible OSPF interface hello and dead intervals on both peers.
  4. Avoid aggressive timers without observing CPU and path loss conditions.

Explanation

Correct Answers

C:

This is the implementation element for the Medical Annex case: OSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists. The specific action Set compatible OSPF interface hello and dead intervals on both peers addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Medical Annex. Avoid aggressive timers without observing CPU and path loss conditions prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

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 hello and dead timers requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

B:

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 hello and dead timers requirement in Medical Annex and is not one of the two controls requested. The direct mechanism here is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

Question 738

At Central Hall, guest VLAN 260 broadcasts DHCP discover but the helper points to an unreachable server. Which observation most directly isolates the likely cause before any change?

  1. Trace where client frames exit the AP versus enter the Aruba gateway datapath.
  2. Examine relay counters helper destination server response and security filtering.
  3. Examine AP boot sequence neighbor LLDP uplink VLAN and address acquisition.
  4. Examine LACP actor partner keys synchronization and individual member states.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is Campus DHCP relay. DHCP relay forwards client requests across routed boundaries; switching alone does not. Inspect relay counters helper destination server response and security filtering is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

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 Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

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 Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

D:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is dHCP relay forwards client requests across routed boundaries; switching alone does not

Question 739

At North Library, aPs have oversized cells and clients remain attached to distant radios after moving floors. What observable outcome would prove this repair actually works?

  1. Generate concurrent voice and bulk traffic and compare latency under load.
  2. Stress uplink and confirm voice stays timely without starvation of other classes.
  3. Walk test improved roaming and reduced overlap at the target busy locations.
  4. Verify authorized voice gets its intended queue while bulk traffic does not.

Explanation

Correct Answer

C:

For North Library, the decisive mechanism is RF power tuning. Excess transmit power can increase interference and sticky-client behavior. Walk test improved roaming and reduced overlap at the target busy locations supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

B:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

D:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the North Library case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

Question 740

At Transit Operations Center, the campus can authenticate users but SOC logs cannot correlate sessions to identities. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect TLS handshake certificate issuer expiry and ClearPass authentication log.
  2. Inspect client TLS validation errors certificate SAN and trusted issuer store.
  3. Inspect start interim and stop records mapped to the NAD and user.
  4. Inspect association RSN capability and failed security negotiation status.

Explanation

Correct Answer

C:

For Transit Operations Center, the decisive mechanism is RADIUS accounting traceability. Authentication and accounting provide different information and require separate configuration. Inspect start interim and stop records mapped to the NAD and user is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to EAP-TLS client certificate validation, where eAP-TLS authenticates possession of the client certificate private key and validates trust In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration

B:

This is relevant to EAP-TLS RADIUS server certificate, where mutual TLS requires client-side confidence in the EAP server identity In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration

D:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication and accounting provide different information and require separate configuration
