Question 620

At Research Hub, a student housing WLAN adds many tenant SSIDs and management airtime becomes excessive. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Perform an active site survey covering attenuation interference and realistic client density.
  2. Consolidate unnecessary WLAN profiles and use targeted zones when appropriate.
  3. Investigate noise/interference and target adequate SNR rather than raising AP power blindly.
  4. Apply an RF plan with reasonable channel reuse and channel width for expected density.

Explanation

Correct Answer

B:

For Research Hub, the decisive mechanism is Excessive SSID beacon overhead. Each advertised SSID sends management traffic that consumes shared airtime. Consolidate unnecessary WLAN profiles and use targeted zones when appropriate 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 Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is each advertised SSID sends management traffic that consumes shared airtime

C:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is each advertised SSID sends management traffic that consumes shared airtime

D:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is each advertised SSID sends management traffic that consumes shared airtime

Question 621

At Research Hub, an untrusted access client sets voice priority on bulk uploads and congests a priority queue. What targeted evidence should the network engineer collect first?

  1. Examine roaming client RSSI overlap and channel utilization across cells.
  2. Examine input DSCP markings trust state and egress queue classification.
  3. Examine associated bands steering outcomes and per-band utilization.
  4. Examine group subscriptions multicast airtime and converted frame counts.

Explanation

Correct Answer

B:

For Research Hub, the decisive mechanism is DSCP trust boundary. QoS trust boundaries determine which received packet markings affect forwarding priority. Inspect input DSCP markings trust state and egress queue classification 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 Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

C:

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 Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

D:

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 Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is qoS trust boundaries determine which received packet markings affect forwarding priority

Question 622

At Hillcrest Campus, a dense library has equal packet counts but very unequal airtime usage across client generations. What measured or witnessed result should be required before signoff?

  1. Show that modern and legacy clients meet appropriate throughput and latency targets.
  2. Measure improved SNR and reduced retry rate without oversizing transmit power.
  3. Check coverage and capacity with representative real devices and occupancy.
  4. Measure acceptable coverage plus SNR at walking and seated client locations.

Explanation

Correct Answer

A:

For Hillcrest Campus, the decisive mechanism is Airtime fairness. Wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity. Show that modern and legacy clients meet appropriate throughput and latency targets supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to RSSI and SNR differentiation, where sNR accounts for interference floor; RSSI alone does not predict useful wireless throughput In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

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 Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

D:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Hillcrest Campus case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wireless medium contention occurs in airtime; equal frame counts do not imply fair capacity

Question 623

At Garden Hall, a campus routing change assigns a core uplink to a stub area on only one side. Which check provides the most useful information for fixing this deployment?

  1. Examine VRRP advertisements gateway owner and virtual MAC state.
  2. Examine active equal-cost routes flow hashing and actual per-link counters.
  3. Examine IPv6 link-local neighbors OSPFv3 interface area and router ID.
  4. Examine OSPF hello packet area values network type and adjacency state.

Explanation

Correct Answer

D:

For Garden Hall, the decisive mechanism is OSPF area membership. OSPF neighbors on a link must agree on essential area and protocol parameters. Inspect OSPF hello packet area values network type and adjacency state is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

B:

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 Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

C:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Garden Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF neighbors on a link must agree on essential area and protocol parameters

Question 624

At Transit Operations Center, a managed workstation receives Access-Reject despite a valid password after certificate renewal. What observable outcome would prove this repair actually works?

  1. Verify the user reaches only the assigned subnet and policy resources.
  2. Correct the applicable rule and see authorized identity succeed while unknown clients fail.
  3. Simulate uplink failure and verify expected rapid convergence without loops.
  4. Prove permitted bidirectional application traffic reaches the endpoint.

Explanation

Correct Answer

B:

For Transit Operations Center, the decisive mechanism is RADIUS Access-Reject root cause. An explicit RADIUS reject can come from credential validation or authorization policy. Correct the applicable rule and see authorized identity succeed while unknown clients fail 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 Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

D:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Transit Operations Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an explicit RADIUS reject can come from credential validation or authorization policy

Question 625

At West Clinic, a replacement distribution switch uses the wrong LACP partner setting and one member is suspended. Which implementation directly addresses this campus fault without replacing the wrong component?

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

Explanation

Correct Answer

B:

For West Clinic, 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

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 West Clinic 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 ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the West Clinic 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 Voice VLAN LLDP-MED, where lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies In the West Clinic 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 626

At Technology Center, an AP was mounted above a metal ceiling and leaves a client shadow zone. How should the engineer validate success against the stated requirement?

  1. Observe lower airtime contention and stable throughput during concurrent client use.
  2. Measure acceptable coverage plus SNR at walking and seated client locations.
  3. Confirm coverage and capacity with representative real devices and occupancy.
  4. Confirm cleaner adjacent-channel use and fewer retransmissions after channel change.

Explanation

Correct Answer

B:

For Technology Center, the decisive mechanism is AP power and cell geometry. AP placement and transmit power affect cell coverage and roaming boundaries. Measure acceptable coverage plus SNR at walking and seated client locations supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

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 Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

D:

This is relevant to Adjacent-channel overlap, where adjacent-channel overlap can corrupt transmissions without the coordination of co-channel sharing In the Technology Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP placement and transmit power affect cell coverage and roaming boundaries

Question 627

At North Library, a data-center uplink bundle stays logically up with just one member even though application capacity requires two. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Inspect ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  2. Inspect active LACP member count and logical aggregate operational thresholds.
  3. Inspect cluster membership firmware compatibility load and tunnel health per gateway.
  4. Inspect keepalive reachability and failure signals independently of ISL health.

Explanation

Correct Answer

B:

For North Library, the decisive mechanism is LACP minimum links. LAG interface health can depend on the configured minimum number of active members. Inspect active LACP member count and logical aggregate operational thresholds is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

C:

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 Library case, Those observations could be normal while the stated fault persists. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

D:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the North Library case, Those observations could be normal while the stated fault persists. The specific mechanism is lAG interface health can depend on the configured minimum number of active members

Question 628

At Garden Hall, a wired workstation reports an EAPOL authentication timeout before it can request a DHCP address. What operational rule should remain in place for later changes?

  1. Maintain reserve PoE capacity and recheck the budget during AP model changes.
  2. Preserve approved transceiver and link-setting baselines for any future port migration.
  3. Restrict sensitive management details on ports where topology advertisement is inappropriate.
  4. Retain RADIUS failover and a defined restricted fallback for the expected device class.

Explanation

Correct Answer

D:

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. Retain RADIUS failover and a defined restricted fallback for the expected device class is an enduring limitation on the operational risk, not simply a one-time passing test.

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

B:

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

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 Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.1X is port-based access control; IP configuration occurs after network admission

Question 630

At West Auditorium, a newly deployed tri-band AP power-limits features when its access-switch closet is near budget. How should the engineer validate success against the stated requirement?

  1. See the AP obtain correct management addressing and report online in Central.
  2. Show the right device online under the approved group and site without exposing another tenant.
  3. Reach the approved server from the intended management interface without leaking access VLANs.
  4. Activate required radios and measure stable power consumption at peak load.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is Access-point PoE capacity. AP radio availability can depend on negotiated power and platform-specific limitations. Enable required radios and measure stable power consumption at peak load supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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 Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

B:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is aP radio availability can depend on negotiated power and platform-specific limitations

C:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the West Auditorium case, That test could pass while the actual user-facing requirement still fails.
