Question 690

At West Auditorium, traffic uses the slow uplink because OSPF cost is unexpectedly lower there. What observable outcome would prove this repair actually works?

  1. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  2. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  3. Test traffic uses the intended lowest-cost path and fails over appropriately.
  4. Fail one gateway and confirm uninterrupted client default-route access within design targets.

Explanation

Correct Answer

C:

For West Auditorium, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Test traffic uses the intended lowest-cost path and fails over appropriately supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

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 West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

Question 691

At South Science Wing, a new AP was patched to an access port without its management VLAN. What operational rule should remain in place for later changes?

  1. Use controlled serial-number ownership checks and avoid blindly claiming unknown devices.
  2. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  3. Use peer review for group moves that can change many APs or switches simultaneously.
  4. Treat AP port changes as staged network access changes rather than bypassing admission.

Explanation

Correct Answer

D:

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. Treat AP port changes as staged network access changes rather than bypassing admission is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

C:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

Question 692

At Riverside Building, an 802.11 SSID advertises very low basic rates and beacons consume excessive airtime. What should the engineer implement first to correct the stated condition?

  1. Perform an active site survey covering attenuation interference and realistic client density.
  2. Set supported minimum data rates balancing coverage and management-frame airtime.
  3. Use an RF plan with reasonable channel reuse and channel width for expected density.
  4. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.

Explanation

Correct Answer

B:

For Riverside Building, the decisive mechanism is Minimum basic rates. Low mandatory rates can enlarge cells and increase management airtime overhead. Set supported minimum data rates balancing coverage and management-frame airtime establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to RF predictive versus active survey, where predictive RF planning does not replace measured real-world attenuation and utilization In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is low mandatory rates can enlarge cells and increase management airtime overhead

C:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is low mandatory rates can enlarge cells and increase management airtime overhead

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 Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is low mandatory rates can enlarge cells and increase management airtime overhead

Question 693

At Transit Operations Center, dual-band clients crowd 2.4-GHz radios despite healthy 5-GHz capacity. Which observation most directly isolates the likely cause before any change?

  1. Inspect portal redirect RADIUS or guest authorization events and the effective client role.
  2. Compare per-band association distributions RSSI and steering responses.
  3. Inspect cluster health tunnel termination count CPU and per-member forwarding.
  4. Compare spatial signal maps channel overlap and client roaming behavior.

Explanation

Correct Answer

B:

For Transit Operations Center, the decisive mechanism is Band steering behavior. Band steering guides capable clients toward suitable bands but client behavior still matters. Compare per-band association distributions RSSI and steering responses is the most direct way to isolate this particular failure before making a change.

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 Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering guides capable clients toward suitable bands but client behavior still matters

C:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering guides capable clients toward suitable bands but client behavior still matters

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Transit Operations Center case, Those observations could be normal while the stated fault persists. The specific mechanism is band steering guides capable clients toward suitable bands but client behavior still matters

Question 694

At Arts Pavilion, a critical voice queue experiences latency because every egress queue uses weighted round-robin. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Evaluate supported multicast conversion and membership control for the audience size.
  2. Rate-limit or police untrusted high-priority markings.
  3. Use supported egress queue scheduling with bounded high-priority service treatment.
  4. Allow documented compatibility cases instead of forcing a universal band cutoff.

Explanation

Correct Answers

B:

This is the continuing risk-control element for Arts Pavilion. Rate-limit or police untrusted high-priority markings prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

C:

This is the implementation element for the Arts Pavilion case: Priority scheduling affects service latency but requires careful queue sizing. The specific action Use supported egress queue scheduling with bounded high-priority service treatment addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

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 Strict priority queue use requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is priority scheduling affects service latency but requires careful queue sizing

D:

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 Strict priority queue use requirement in Arts Pavilion and is not one of the two controls requested. The direct mechanism here is priority scheduling affects service latency but requires careful queue sizing

Question 695

At East Student Center, a lab port meant for one kiosk accumulates MAC addresses from an unauthorized hub. How should the engineer validate success against the stated requirement?

  1. Connect an authorized endpoint and then an extra device to verify expected treatment.
  2. See device traffic only in its assigned broadcast domain and expected address scope.
  3. Generate tagged traffic across all intended VLANs and confirm blocked VLANs remain isolated.
  4. Confirm untagged test frames land in the same approved VLAN at both endpoints.

Explanation

Correct Answer

A:

For East Student Center, the decisive mechanism is Port MAC limits. MAC address limits restrict excessive downstream identities on a switchport. Connect an authorized endpoint and then an extra device to verify expected treatment supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

C:

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 East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

D:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mAC address limits restrict excessive downstream identities on a switchport

Question 696

At Central Hall, an access switch aggregates two fiber uplinks but both links remain independently forwarding. What recurring protection should accompany this configuration?

  1. Guard against arbitrary untrusted client VLAN tagging on shared ports.
  2. Guard against parallel standalone links before the bundle is fully formed.
  3. Stage ACL changes with console rollback to avoid management lockout.
  4. Do not enable jumbo frames on one device without validating intermediate hops.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is Dynamic LACP bundle. LACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient. Guard against parallel standalone links before the bundle is fully formed is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

C:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

D:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is lACP negotiates physical links into a logical bundle; simply cabling two ports is insufficient

Question 697

At Arts Pavilion, two distribution gateways both try to become master after an inconsistent VRRP priority update. What targeted evidence should the network engineer collect first?

  1. Examine OSPF hello packet area values network type and adjacency state.
  2. Cross-check default prefixes distances next-hop health and forwarding decisions.
  3. Examine received hello timers and neighbor reset reasons.
  4. Examine VRRP advertisements gateway owner and virtual MAC state.

Explanation

Correct Answer

D:

For Arts Pavilion, the decisive mechanism is First-hop gateway election. VRRP abstracts the default gateway across eligible routing devices. Inspect VRRP advertisements gateway owner and virtual MAC state 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 Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

B:

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 Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

C:

This is relevant to OSPF hello and dead timers, where oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is VRRP abstracts the default gateway across eligible routing devices

Question 698

At Innovation Studio, a small office increased AP power to maximum and co-channel interference became worse. Which configuration change best fits the network requirement and observed behavior?

  1. Adjust transmit power with channel plan and measured minimum edge SNR.
  2. Apply supported egress queue scheduling with bounded high-priority service treatment.
  3. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  4. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy.

Explanation

Correct Answer

A:

For Innovation Studio, the decisive mechanism is RF power tuning. Excess transmit power can increase interference and sticky-client behavior. Adjust transmit power with channel plan and measured minimum edge SNR establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

C:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

D:

This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the Innovation Studio case, Changing that neighboring feature does not implement the missing function. The specific mechanism is excess transmit power can increase interference and sticky-client behavior

Question 699

At Engineering Tower, iP phones boot in the data VLAN because the switch no longer advertises LLDP-MED voice policy. Which observation most directly isolates the likely cause before any change?

  1. Inspect untagged packet capture and both peers native VLAN configuration.
  2. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags.
  3. Inspect interface VLAN mode learned MAC address and DHCP lease subnet.
  4. Compare allowed VLAN list tagging and egress counters at both ends.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is Voice VLAN LLDP-MED. LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. Inspect neighbor LLDP-MED TLVs and phone versus PC VLAN tags is the most direct way to isolate this particular failure before making a change.

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 Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

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 Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies

Question 700

At New Teaching Block, a repaired IoT endpoint should move to its normal role without disconnecting the cable. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Retain emergency break-glass administration documented and monitored.
  2. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  3. Activate supported RADIUS CoA workflow and compatible switch authorization transitions.
  4. Restrict CoA source addresses and avoid unauthorized session terminations.

Explanation

Correct Answers

C:

This is the implementation element for the New Teaching Block case: Change of Authorization can change an active network access session's policy state. The specific action Enable supported RADIUS CoA workflow and compatible switch authorization transitions addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for New Teaching Block. Restrict CoA source addresses and avoid unauthorized session terminations prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be an ongoing precaution for TACACS+ admin AAA distinction: Administrative command authorization and client-port 802.1X solve different AAA problems. It does not resolve the RADIUS change of authorization requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is change of Authorization can change an active network access session's policy state

B:

This may be a configuration step for Supplicant reauthentication intervals: Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. It does not resolve the RADIUS change of authorization requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is change of Authorization can change an active network access session's policy state
