Question 980

At South Science Wing, a team assumes every station will get simultaneous spatial streams merely because AP supports MU-MIMO. How should the engineer validate success against the stated requirement?

  1. Check coverage and capacity with representative real devices and occupancy.
  2. Observe lower airtime contention and stable throughput during concurrent client use.
  3. Measure actual multi-client throughput without asserting all clients can use MU-MIMO.
  4. Measure improved SNR and reduced retry rate without oversizing transmit power.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is MU-MIMO application. MU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow. Measure actual multi-client throughput without asserting all clients can use MU-MIMO supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

B:

This is relevant to Co-channel contention, where co-channel APs share contention airtime even if their signals are individually strong In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

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 South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mU-MIMO can serve compatible users with spatial multiplexing when channel conditions allow

Question 981

At North Library, aPs have oversized cells and clients remain attached to distant radios after moving floors. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Adjust transmit power with channel plan and measured minimum edge SNR.
  2. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  3. Maintain consistent DSCP-to-WMM mapping end to end.
  4. Avoid exceeding regulatory EIRP limits or creating asymmetric AP/client link budgets.

Explanation

Correct Answers

A:

This is the implementation element for the North Library case: Excess transmit power can increase interference and sticky-client behavior. The specific action Adjust transmit power with channel plan and measured minimum edge SNR addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for North Library. Avoid exceeding regulatory EIRP limits or creating asymmetric AP/client link budgets prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

B:

This may be a configuration step for DSCP trust boundary: QoS trust boundaries determine which received packet markings affect forwarding priority. It does not resolve the RF power tuning requirement in North Library and is not one of the two controls requested. The direct mechanism here is excess transmit power can increase interference and sticky-client behavior

C:

This may be an ongoing precaution for WMM access categories: 802.11e WMM prioritizes wireless contention via different access categories. It does not resolve the RF power tuning requirement in North Library and is not one of the two controls requested. The direct mechanism here is excess transmit power can increase interference and sticky-client behavior

Question 982

At Arts Pavilion, an aggregation VSX pair loses its inter-switch link and one peer cannot synchronize state. Which controlled configuration is most likely to restore the required service?

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

Explanation

Correct Answer

C:

For Arts Pavilion, 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 Arts Pavilion 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 Loop protection, where loop detection complements STP by containing accidental edge loops In the Arts Pavilion 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 VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the Arts Pavilion 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 983

At New Teaching Block, a distribution gateway receives community-marked backup networks but applies no matching policy. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Avoid aggressive timers without observing CPU and path loss conditions.
  2. Retain community namespace and policy interpretations documented across peers.
  3. Synchronize OSPF area ID and supported area type at both neighboring interfaces.
  4. Match the approved BGP community in a route map and apply the correct import/export action.

Explanation

Correct Answers

B:

This is the continuing risk-control element for New Teaching Block. Keep community namespace and policy interpretations documented across peers 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 New Teaching Block case: BGP communities are policy labels requiring an explicit matching route policy. The specific action Match the approved BGP community in a route map and apply the correct import/export action addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

A:

This may be an ongoing precaution for OSPF hello and dead timers: OSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists. It does not resolve the BGP community route policy requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is bGP communities are policy labels requiring an explicit matching route policy

C:

This may be a configuration step for OSPF area membership: OSPF neighbors on a link must agree on essential area and protocol parameters. It does not resolve the BGP community route policy requirement in New Teaching Block and is not one of the two controls requested. The direct mechanism here is bGP communities are policy labels requiring an explicit matching route policy

Question 984

At Engineering Tower, an office user cross-patches two wall ports and triggers a broadcast storm. What should be examined to confirm the actual failure mechanism?

  1. Examine ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  2. Examine loop-protect logs MAC flapping and abnormal broadcast traffic.
  3. Cross-check configured and operational gateway state and ARP entries on both VSX peers.
  4. Examine keepalive reachability and failure signals independently of ISL health.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is Loop protection. Loop detection complements STP by containing accidental edge loops. Inspect loop-protect logs MAC flapping and abnormal broadcast traffic 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 Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

C:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

D:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is loop detection complements STP by containing accidental edge loops

Question 985

At Technology Center, a branch has two default routes but prefers the backup due to unexpected distance. Which investigation most directly explains why the intended service is not working?

  1. Examine IPv6 link-local neighbors OSPFv3 interface area and router ID.
  2. Examine VRRP advertisements gateway owner and virtual MAC state.
  3. Cross-check default prefixes distances next-hop health and forwarding decisions.
  4. Examine relay forwarded packets GIADDR server routes and ACL logs.

Explanation

Correct Answer

C:

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. Compare default prefixes distances next-hop health and forwarding decisions is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

D:

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, Those observations could be normal while the stated fault persists. The specific mechanism is default route 0.0.0.0/0 applies when no more specific IPv4 route matches

Question 986

At Administration Block, an API monitoring script requests config values but accidentally reads only interface status attributes. Which configuration change best fits the network requirement and observed behavior?

  1. Use documented REST selectors and read writable fields before controlled updates.
  2. Configure a supported mirror session with explicit source direction and valid destination port.
  3. Configure User Experience Insight sensor tests that reflect actual user networks and destinations.
  4. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.

Explanation

A:

For Administration Block, the decisive mechanism is REST API selector use. REST representation selection and HTTP method choice affect what configuration is retrieved or changed. Use documented REST selectors and read writable fields before controlled updates establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to Port mirroring PCAP, where port mirroring copies selected frames for observation but is not a live forwarding path In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

C:

This is relevant to UXI client experience probes, where uXI sensors run synthetic end-user workflows to reveal service-layer failures In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

D:

This is relevant to NAE monitor rule, where nAE agents monitor local switch state and can correlate rule conditions over time In the Administration Block case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rEST representation selection and HTTP method choice affect what configuration is retrieved or changed

Question 987

  1. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  2. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  3. Set up matching active-gateway address and MAC settings on the applicable VSX SVIs.
  4. Set up a separate reachable VSX keepalive path with valid source and peer addressing.

Explanation

Correct Answer

A:

For Garden Hall, the decisive mechanism is AOS 10 gateway cluster. An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. Create a compatible gateway cluster with capacity and mobility requirements in Central establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

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 Garden Hall case, Changing that neighboring feature does not implement the missing function.
