• Question 81:

  A network administrator at a marketing company is deploying a Cisco Catalyst 9800 Series Wireless Controller running Cisco IOS XE 17.x.

  The corporate WLAN named XYZ-Guest supports visitor devices.

  To address intermittent connectivity issues due to client association limits and short session timeouts, the network administrator must optimize the WLAN to allow more client connections and extend session timeouts for the devices.

  The administrator must set the maximum number of clients for the XYZ-Guest WLAN to 50 and must set a session timeout to prevent frequent device disconnections.

  Which two commands must be configured on the controller? (Choose two.)

  A. wlan XYZ-Guest 1 XYZ-Guest client max-association 50
  B. wireless profile policy XYZ-Guest-Pol client session timeout 2800
  C. wlan XYZ-Guest 1 XYZ-Guest client session timeout 2800
  D. wireless profile policy XYZ-Guest-Pol session timeout 2800
  E. wlan XYZ-Guest 1 XYZ-Guest client association limit 50
  C. wlan XYZ-Guest 1 XYZ-Guest client session timeout 2800
  E. wlan XYZ-Guest 1 XYZ-Guest client association limit 50

  ---

  Explanation

  This scenario centers on A network administrator at a marketing company is deploying a Cisco Catalyst 9800 Series Wireless Controller running Cisco IOS XE 17.x. The corporate WLAN named XYZ-Guest supports visitor devices. The response wlan XYZ-Guest 1 XYZ-Guest client session timeout 2800; wlan XYZ-Guest 1 XYZ-Guest client association limit 50 works at that same control point.

  Protocol questions depend on the exact 802.11 function involved. Airtime scheduling, frame exchange, channel behavior, and secure roaming each solve a different problem. The chosen setting maps to the protocol mechanism described by the stem rather than to a controller administration task or a general monitoring feature.

  wlan XYZ-Guest 1 XYZ-Guest client max-association 50 belongs to a different workflow and would leave the stated condition unresolved. wireless profile policy XYZ-Guest-Pol client session timeout 2800 may be useful elsewhere, but it does not apply the control that the stem is asking for. wireless profile policy XYZ- Guest-Pol session timeout 2800 changes an adjacent setting instead of the mechanism that produces the

  required result.

  The tested habit is to avoid picking a familiar wireless term unless it changes the exact condition in the question.

• Question 82:

  What is the maximum transmit power level allowed for 2.4 GHz in the United States?

  A. 20 dBm
  B. 23 dBm
  C. 30 dBm
  D. 36 dBm
  C. 30 dBm

  ---

  Explanation

  The key is to match the requested effect, What is the maximum transmit power level allowed for 2.4 GHz in the United States?, with the feature or command that actually produces it; that points to 30 dBm.

  RF questions should be solved from measurable behavior. Signal level, noise, channel restrictions, interference classification, and propagation effects determine whether a link is stable and compliant. This feature is tied to that RF behavior, so it explains the observed result without changing unrelated WLAN security or management settings.

  20 dBm can sound related, but it does not own the behavior being tested. 23 dBm omits the part of the configuration that actually enforces the requested outcome. 36 dBm shifts attention away from the condition that the client, AP, or controller must satisfy.

  In production troubleshooting, that distinction matters because changing the wrong layer can leave the original failure untouched.

  A complete review also checks whether the choice would still solve the problem if all other settings stayed the same. That test favors the correct choice because it changes the feature, protocol, or policy named by the question. The distractors may be legitimate Cisco wireless concepts, but they would send the engineer toward a different task and leave the stated requirement unresolved.

• Question 83:

  What defines RSSI in radio signal measurements?

  A. Detected amplitude level at radio receiver
  B. Noise generated by interference
  C. QoS network packet marking method
  D. Wireless radio signal service ID
  A. Detected amplitude level at radio receiver

  ---

  Explanation

  For this scenario, Detected amplitude level at radio receiver is not just related terminology; it is the part that satisfies.

  What defines RSSI in radio signal measurements?

  RF questions should be solved from measurable behavior. Signal level, noise, channel restrictions, interference classification, and propagation effects determine whether a link is stable and compliant. The selected mechanism is tied to that RF behavior, so it explains the observed result without changing unrelated WLAN security or management settings.

  Noise generated by interference does not provide the specific RF, security, forwarding, management, or automation behavior that is required. QoS network packet marking method would be considered only for a different symptom or design goal. Wireless radio signal service ID can sound related, but it does not own the behavior being tested.

  A good review method is to ask whether the choice would still solve the issue if every unrelated setting remained unchanged.

  That reading also helps with the distractors: they may name real wireless concepts, but they do not calculate, configure, or enforce the specific behavior requested here. In review, ask whether applying the choice would immediately change the failure, measurement, policy, or workflow in the stem; if it would not, it should be eliminated.

• Question 84:

  A warehouse wireless survey shows acceptable RSSI on handheld scanners, but retries increase when nearby equipment is active. The noise floor rises from -95 dBm to -78 dBm during the problem period.

  What is the most likely RF impact?

  A. The SNR decreases and data retries increase.
  B. The antenna gain increases for all clients.
  C. The channel width automatically narrows to 5 MHz.
  D. The regulatory domain changes to a lower power class.
  A. The SNR decreases and data retries increase.

  ---

  Explanation

  Here, The SNR decreases and data retries increase. is tied to the actual requirement in the stem: A warehouse wireless survey shows acceptable RSSI on handheld scanners, but retries increase when nearby equipment is active. The noise floor rises from -95 dBm to -78 dBm during the problem period.

  What is the most likely RF impact?

  RF questions should be solved from measurable behavior. Signal level, noise, channel restrictions, interference classification, and propagation effects determine whether a link is stable and compliant. The chosen behavior is tied to that RF behavior, so it explains the observed result without changing unrelated WLAN security or management settings.

  The antenna gain increases for all clients. changes an adjacent setting instead of the mechanism that produces the required result. The channel width automatically narrows to 5 MHz. addresses a different failure domain, so it would not close the gap described here. The regulatory domain changes to a lower power class. is too broad or aimed at the wrong layer for this scenario.

  This keeps the reasoning tied to the implementation detail rather than to broad wireless terminology.

• Question 85:

  What is a characteristic of gain in wireless antenna design?

  A. Scale used for calculating system loss
  B. Checksum figure appended to signal blocks
  C. Amount of increased energy sent toward a specific direction
  D. Standard temperature tolerance during wireless operation
  C. Amount of increased energy sent toward a specific direction

  ---

  Explanation

  The stem narrows the problem to What is a characteristic of gain in wireless antenna design? In that context, Amount of increased energy sent toward a specific direction is the setting or feature that applies.

  Antenna questions are about pattern and energy concentration. Gain changes how energy is focused, not the authentication method, VLAN assignment, or controller policy. This feature matches the coverage shape or gain behavior described in the stem, which is why it is preferred over unrelated wireless features.

  Scale used for calculating system loss may be useful elsewhere, but it does not apply the control that the stem is asking for. Checksum figure appended to signal blocks changes an adjacent setting instead of the mechanism that produces the required result. Standard temperature tolerance during wireless operation addresses a different failure domain, so it would not close the gap described here.

  That is why the correct selection follows the requirement directly instead of merely belonging to the same Cisco wireless product family.

• Question 86:

  Refer to the exhibit.

  

  A network administrator is working on a WLC to enable user access for contractor desktops using WPA2- Enterprise using EAP-TTLS. The administrator verified the external authentication configuration and now must test network connectivity.

  Which code snippet must be added to the box in the code to complete the configuration on the WLC that supports authentication with an external server?

  A. aaa group server radius RADIUS-GRP
  B. aaa group server aaa RADIUS-GRP
  C. aaa server group server radius RADIUS-GRP
  D. aaa server group server radius RADIUS-GRP
  A. aaa group server radius RADIUS-GRP

  ---

  Explanation

  aaa group server radius RADIUS-GRP fits because the item is asking about this condition: A network administrator is working on a WLC to enable user access for contractor desktops using WPA2-Enterprise using EAP-TTLS. The administrator verified the external authentication configuration and now must test network connectivity.

  Security questions should separate authentication, authorization, and policy enforcement. The WLAN security method gets the client on the network, while RADIUS and policy attributes decide what access the client receives. That configuration is the piece that enables or applies that security behavior; the other choices either skip the external method, use the wrong authentication model, or affect a separate policy

  area.

  aaa group server aaa RADIUS-GRP can sound related, but it does not own the behavior being tested. aaa server group server radius RADIUS-GRP omits the part of the configuration that actually enforces the requested outcome. aaa server group server radius RADIUS-GRP shifts attention away from the condition that the client, AP, or controller must satisfy.

  In production troubleshooting, that distinction matters because changing the wrong layer can leave the original failure untouched.

• Question 87:

  Which wireless connection occurs when there are no physical obstacles between the receiver and transmitter?

  A. attenuation
  B. line-of-sight
  C. reflection
  D. beamforming
  B. line-of-sight

  ---

  Explanation

  The useful clue is this requirement: Which wireless connection occurs when there are no physical obstacles between the receiver and transmitter? That clue points to line-of-sight.

  RF questions should be solved from measurable behavior. Signal level, noise, channel restrictions, interference classification, and propagation effects determine whether a link is stable and compliant. This feature is tied to that RF behavior, so it explains the observed result without changing unrelated WLAN security or management settings.

  attenuation is too broad or aimed at the wrong layer for this scenario. reflection does not provide the specific RF, security, forwarding, management, or automation behavior that is required. beamforming would be considered only for a different symptom or design goal.

  For exam purposes, separate association, authentication, authorization, forwarding, RF behavior, and management visibility before selecting a command or feature.

  A complete review also checks whether the choice would still solve the problem if all other settings stayed the same. That test favors the correct choice because it changes the feature, protocol, or policy named by the question. The distractors may be legitimate Cisco wireless concepts, but they would send the engineer toward a different task and leave the stated requirement unresolved.

• Question 88:

  A branch office uses APs that must locally switch client traffic and continue serving users during a WAN outage. The controller should still provide centralized configuration when the WAN is available.

  Which AP deployment mode meets these requirements?

  A. Sniffer
  B. Monitor
  C. FlexConnect
  D. Rogue detector
  C. FlexConnect

  ---

  Explanation

  A direct reading of the item leads to FlexConnect, because the stated requirement is A branch office uses APs that must locally switch client traffic and continue serving users during a WAN outage. The controller should still provide centralized configuration when the WAN is available. Which AP deployment mode meets these requirements?

  Branch designs usually test the difference between central management and local data handling.

  FlexConnect behavior is chosen when the AP must keep useful service at the site while still being managed by the controller. That configuration fits that branch requirement because it changes forwarding or authentication behavior at the AP site rather than relying on an always-available central path.

  Sniffer may be useful elsewhere, but it does not apply the control that the stem is asking for. Monitor changes an adjacent setting instead of the mechanism that produces the required result. Rogue detector addresses a different failure domain, so it would not close the gap described here.

  That is why the correct selection follows the requirement directly instead of merely belonging to the same Cisco wireless product family.

• Question 89:

  Refer to the exhibit.

  

  A network administrator must configure a client management parameter for a wireless deployment in a multi-site enterprise.

  The enterprise is using Cisco ISE as the management platform to oversee wireless access policies. To meet the organization's compliance requirements, all wireless endpoints must be evaluated against a posture policy before gaining access.

  Which configuration change must be applied on the WLAN level of the WLC to meet the requirement?

  A. config wlan WLAN-staff enable aaa-override
  B. wireless profile policy WLAN-Staffnac
  C. config wlan WLAN-StaffWLAN-staff radius enable
  D. wireless profile policy WLAN-Staff config wlan 5 enable radius
  A. config wlan WLAN-staff enable aaa-override

  ---

  Explanation

  config wlan WLAN-staff enable aaa-override is preferred because it changes the behavior described here: A network administrator must configure a client management parameter for a wireless deployment in a multi-site enterprise. The enterprise is using Cisco ISE as the management platform to oversee wireless access policies. To meet the organization's compliance requirements.

  Security questions should separate authentication, authorization, and policy enforcement. The WLAN security method gets the client on the network, while RADIUS and policy attributes decide what access the client receives. This choice is the piece that enables or applies that security behavior; the other choices either skip the external method, use the wrong authentication model, or affect a separate policy area.

  wireless profile policy WLAN-Staffnac addresses a different failure domain, so it would not close the gap described here. config wlan WLAN-StaffWLAN-staff radius enable is too broad or aimed at the wrong layer for this scenario. wireless profile policy WLAN-Staff config wlan 5 enable radius does not provide the specific RF, security, forwarding, management, or automation behavior that is required. The answer should therefore be evaluated by effect, not by how recognizable the command or platform name appears.

• Question 90:

  What is a characteristic of 20 MHz channel width in a wireless network?

  A. Narrowest channel width in the 2.4 GHz band
  B. Increases authentication handoff frequency
  C. Supports automatic client reassociation
  D. Higher throughput than wider channels
  A. Narrowest channel width in the 2.4 GHz band

  ---

  Explanation

  The controlling requirement is What is a characteristic of 20 MHz channel width in a wireless network? The choice Narrowest channel width in the 2.4 GHz band maps to that requirement directly.

  Protocol questions depend on the exact 802.11 function involved. Airtime scheduling, frame exchange, channel behavior, and secure roaming each solve a different problem. This feature maps to the protocol mechanism described by the stem rather than to a controller administration task or a general monitoring feature.

  Increases authentication handoff frequency omits the part of the configuration that actually enforces the requested outcome. Supports automatic client reassociation shifts attention away from the condition that the client, AP, or controller must satisfy. Higher throughput than wider channels belongs to a different workflow and would leave the stated condition unresolved.

  The key lesson is that Cisco wireless features are usually scoped tightly, and the scope determines whether a choice is usable.

  That reading also helps with the distractors: they may name real wireless concepts, but they do not calculate, configure, or enforce the specific behavior requested here. In review, ask whether applying the choice would immediately change the failure, measurement, policy, or workflow in the stem; if it would not, it should be eliminated.
