Question 690

A university guest portal permits repeated brute-force passcode attempts without meaningful throttling. The recommended remediation is: Apply supported portal rate controls and monitor attempted abuse without denying ordinary guests. What evidence should be required before closing the incident?

  1. A simulated abusive login pattern is limited while authorized guests complete the sign-in process
  2. The guest client moves to permitted access and reaches approved external destinations after sign-in
  3. An unauthenticated guest is redirected and gains only permitted access after completing the portal
  4. Guest clients on the intended SSID see the approved form and complete sign-in

Explanation

Correct Answer

A:

A simulated abusive login pattern is limited while authorized guests complete the sign-in process directly tests the proposed corrective action: Apply supported portal rate controls and monitor attempted abuse without denying ordinary guests. Guest portals require effective prelogin, HTTPS, redirection, authentication and postlogin service authorization controls.

Incorrect Answers

B:

That observation would confirm another situation: A campus guest portal redirects correctly but its backend authorization succeeds while the user remains isolated after acceptance. Here the selected action should produce: A simulated abusive login pattern is limited while authorized guests complete the sign-in process.

C:

This check instead concerns a separate case: A hotel guest portal displays successfully but allows full Internet browsing without requiring the configured acceptance step. Here the selected action should produce: A simulated abusive login pattern is limited while authorized guests complete the sign-in process.

D:

That evidence would establish success in a different scenario: An engineer customizes a captive portal on a WLAN template but applies a different site-level WLAN to the target APs. Here the selected action should produce: A simulated abusive login pattern is limited while authorized guests complete the sign-in process.

Question 691

A client can reach internal resources over the WLAN but external hostnames never resolve. The change request proposes: Test approved DNS server reachability and client configuration without changing SSID authentication. Which result would demonstrate the intended network outcome?

  1. The client resolves permitted names and reaches their destinations while network access remains restricted
  2. The rejected EAP step is identified and a valid managed identity completes login
  3. The AP advertises the campus SSID and the valid student completes association and authentication
  4. A fresh guest completes portal flow and accesses approved destinations after the fix

Explanation

Correct Answer

A:

The client resolves permitted names and reaches their destinations while network access remains restricted directly tests the proposed corrective action: Test approved DNS server reachability and client configuration without changing SSID authentication. Wireless faults should be isolated at the actual RF, association, authorization, DHCP, policy or application stage.

Incorrect Answers

B:

This check instead concerns a separate case: A hospital handset fails enterprise WLAN authentication while the AP radio reports good coverage. Here the selected action should produce: The client resolves permitted names and reaches their destinations while network access remains restricted.

C:

That evidence would establish success in a different scenario: A student cannot join the expected wireless network because its AP is claimed but not assigned to the right campus site. Here the selected action should produce: The client resolves permitted names and reaches their destinations while network access remains restricted.

D:

That observation would confirm another situation: A guest portal opens correctly but permitted users cannot reach the Internet after submitting the form. Here the selected action should produce: The client resolves permitted names and reaches their destinations while network access remains restricted.

Question 692

An operations lead excludes all low-performing access points from an SLE view solely to make the dashboard display green. The site engineer plans to: Keep scope and exclusion rules aligned with actual service ownership and disclose all excluded devices. What is the best acceptance test for this change?

  1. Old and new devices are represented and any subgroup degradation remains visible
  2. The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health
  3. A floor-specific report identifies overloaded cells otherwise hidden by the site mean
  4. The SLE report includes the affected AP population or explicitly explains a justified exclusion

Explanation

Correct Answer

D:

The SLE report includes the affected AP population or explicitly explains a justified exclusion directly tests the proposed corrective action: Keep scope and exclusion rules aligned with actual service ownership and disclose all excluded devices. SLE thresholds must express documented user-service goals with transparent scope, denominator and change history.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A school changes a radio channel plan and then selects only the students' most capable laptops for postchange SLE verification. Here the selected action should produce: The SLE report includes the affected AP population or explicitly explains a justified exclusion.

B:

That observation would confirm another situation: An engineer adjusts SLE settings after an outage but compares the new success percentage directly with an old threshold. Here the selected action should produce: The SLE report includes the affected AP population or explicitly explains a justified exclusion.

C:

This check instead concerns a separate case: A shopping center treats the site-wide Capacity SLE as a universal performance guarantee without checking client distribution across floors. Here the selected action should produce: The SLE report includes the affected AP population or explicitly explains a justified exclusion.

Question 693

A device is accidentally assigned to a similarly named site in another time zone and displays unrelated troubleshooting data. The incident lead approves this next step: Validate stable site identifiers and move the AP into the actual managed location. Which postchange finding most directly validates the action?

  1. The site inventory includes the AP and it advertises the approved service SSIDs
  2. The AP selects permitted channels and the site record matches documented installation coordinates
  3. The AP's organization/site identifiers and incident timeline match its physical installation
  4. Observed tags and AP positions align to the actual building map after correction

Explanation

Correct Answer

C:

The AP's organization/site identifiers and incident timeline match its physical installation directly tests the proposed corrective action: Validate stable site identifiers and move the AP into the actual managed location. Mist organizations provide ownership boundaries while sites represent actual locations with correct device membership and metadata.

Incorrect Answers

A:

That observation would confirm another situation: An access point is correctly claimed to an organization but remains unassigned to a physical site and receives no WLAN template. Here the selected action should produce: The AP's organization/site identifiers and incident timeline match its physical installation.

B:

This check instead concerns a separate case: An engineer creates a Mist site without setting the appropriate country and the AP cannot use the required legal wireless channels. Here the selected action should produce: The AP's organization/site identifiers and incident timeline match its physical installation.

D:

That evidence would establish success in a different scenario: An international company uses the same geographic address for two Mist sites and asset location results appear on the wrong floorplan. Here the selected action should produce: The AP's organization/site identifiers and incident timeline match its physical installation.

Question 694

A technician creates multiple WLAN objects with the same display name and cannot identify which one is bound to the AP template. The intended correction is: Use stable object identifiers and inspect effective bindings rather than relying on names alone. What evidence most clearly distinguishes success from a partial fix?

  1. An inventory export maps the target AP to the unique intended WLAN object
  2. The returning AP reports the current approved profile and a client test validates actual service
  3. Guest clients enter the correct campus VLAN without making unrelated SSIDs inconsistent
  4. A dry-run preview includes only the intended AP and site identifiers for the receiving customer

Explanation

Correct Answer

A:

An inventory export maps the target AP to the unique intended WLAN object directly tests the proposed corrective action: Use stable object identifiers and inspect effective bindings rather than relying on names alone. Reusable Mist configuration objects require correct references, inheritance, target membership and verified device delivery.

Incorrect Answers

B:

This check instead concerns a separate case: A site policy makes changes after an AP has gone offline, but operators assume the device has immediately received every update. Here the selected action should produce: An inventory export maps the target AP to the unique intended WLAN object.

C:

That evidence would establish success in a different scenario: A WLAN template uses a static VLAN identifier that is different at two physical campuses. Here the selected action should produce: An inventory export maps the target AP to the unique intended WLAN object.

D:

That observation would confirm another situation: An MSP copies one customer's site group label into another tenant's organization and accidentally targets the wrong access points. Here the selected action should produce: An inventory export maps the target AP to the unique intended WLAN object.

Question 695

An enterprise replaces APs but leaves old location-floorplan coordinates, producing incorrect radio maps and asset positions. The recommended remediation is: Update physical inventory and calibrated location geometry during the replacement change. What evidence should be required before closing the incident?

  1. AP identifiers and actual floorplan placements match surveyed locations after the migration
  2. The commissioning report verifies cloud status, entitlements and approved version for each AP
  3. Pilot evidence documents scanner admission and handoff before broader site deployment
  4. A controlled guest device completes portal sign-in and reaches only approved external destinations

Explanation

Correct Answer

A:

AP identifiers and actual floorplan placements match surveyed locations after the migration directly tests the proposed corrective action: Update physical inventory and calibrated location geometry during the replacement change. The WLAN lifecycle includes requirements, RF survey, compatibility, staged deployment, client acceptance, operation and controlled retirement.

Incorrect Answers

B:

That evidence would establish success in a different scenario: A medical campus treats installing the AP as project completion although firmware and license activation remain incomplete. Here the selected action should produce: AP identifiers and actual floorplan placements match surveyed locations after the migration.

C:

That observation would confirm another situation: A warehouse network upgrade moves from pilot to production without validating older scanner behavior on the new SSID. Here the selected action should produce: AP identifiers and actual floorplan placements match surveyed locations after the migration.

D:

This check instead concerns a separate case: A hotel turns up a guest WLAN but never performs an end-to-end client data path test after portal acceptance. Here the selected action should produce: AP identifiers and actual floorplan placements match surveyed locations after the migration.

Question 696

A WLAN policy for guest clients allows DNS only to one IP address that is no longer used after a network migration. The change request proposes: Update the approved destination or service match using current DNS dependency information. Which result would demonstrate the intended network outcome?

  1. A controlled device reconnect or supported reauthorization applies the new restricted access promptly
  2. Guest clients resolve names through the authorized resolver and cannot use unapproved endpoints
  3. Guest usage continues for approved services while management-plane access is no longer permitted
  4. Guest tests reach permitted external sites but cannot connect to restricted internal services

Explanation

Correct Answer

B:

Guest clients resolve names through the authorized resolver and cannot use unapproved endpoints directly tests the proposed corrective action: Update the approved destination or service match using current DNS dependency information. WxLAN access decisions rely on scoped rule order, trustworthy identity matching and downstream enforcement of permitted services.

Incorrect Answers

A:

That observation would confirm another situation: A hospital updates a restricted WLAN rule but a previously connected device retains an unintended session privilege. Here the selected action should produce: Guest clients resolve names through the authorized resolver and cannot use unapproved endpoints.

C:

This check instead concerns a separate case: A guest WLAN uses an unrestricted allow-all emergency override during a conference and it is never removed. Here the selected action should produce: Guest clients resolve names through the authorized resolver and cannot use unapproved endpoints.

D:

That evidence would establish success in a different scenario: A guest SSID has an allow rule for Internet browsing but a broad earlier permit also grants unrestricted access to internal finance systems. Here the selected action should produce: Guest clients resolve names through the authorized resolver and cannot use unapproved endpoints.

Question 697

A team deploys two edge appliances but both use the same physical power feed and uplink path during a resilience demonstration. The site engineer plans to: Assess independent infrastructure failure domains for the active and backup Mist Edge paths. What is the best acceptance test for this change?

  1. A packet trace verifies guest tunneling and local staff bridging simultaneously
  2. A busy-hour stress test stays within approved per-node utilization and client throughput targets
  3. A controlled power or link failure leaves at least one supported tunnel termination available
  4. Packet and interface evidence confirms the documented tunnel protocol succeeds without opening unrelated services

Explanation

Correct Answer

C:

A controlled power or link failure leaves at least one supported tunnel termination available directly tests the proposed corrective action: Assess independent infrastructure failure domains for the active and backup Mist Edge paths. Mist Edge terminates selected tunneled WLAN data paths and needs independent tunnel, interface, routing, capacity and failover checks.

Incorrect Answers

A:

This check instead concerns a separate case: A university routes staff Wi-Fi locally but demands that visitor WLAN traffic terminate at a datacenter Mist Edge appliance. Here the selected action should produce: A controlled power or link failure leaves at least one supported tunnel termination available.

B:

That evidence would establish success in a different scenario: An administrator adds APs to a tunnel profile but ignores aggregate edge client throughput under conference loading. Here the selected action should produce: A controlled power or link failure leaves at least one supported tunnel termination available.

D:

That observation would confirm another situation: A branch Mist Edge design assumes the AP-to-edge data tunnel uses ordinary HTTPS and applies only management port firewall rules. Here the selected action should produce: A controlled power or link failure leaves at least one supported tunnel termination available.

Question 698

A campus wants to optimize roaming but its RF cells have excessive overlap due to high power on both neighboring access points. The incident lead approves this next step: Use measured overlap and client transition behavior to set cell size and power limits. Which postchange finding most directly validates the action?

  1. A moving scanner test meets roaming and coverage criteria under normal stock loading
  2. Representative clients roam to the intended AP before experiencing excessive weak-link retransmissions
  3. Single-band handsets retain working WLAN admission while compatible devices use the preferred band
  4. A controlled radar-related channel evacuation yields an approved replacement channel with acceptable continuity

Explanation

Correct Answer

B:

Representative clients roam to the intended AP before experiencing excessive weak-link retransmissions directly tests the proposed corrective action: Use measured overlap and client transition behavior to set cell size and power limits. RRM choices balance interference, legal channel/power limits, cell reuse, client needs and actual service-impact evidence.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A warehouse adopts a narrow RF channel plan from an office despite high metal shelving and mobile scanners. Here the selected action should produce: Representative clients roam to the intended AP before experiencing excessive weak-link retransmissions.

C:

That observation would confirm another situation: A roaming optimization policy pushes older handsets toward 5 GHz although those units support only 2.4 GHz. Here the selected action should produce: Representative clients roam to the intended AP before experiencing excessive weak-link retransmissions.

D:

This check instead concerns a separate case: A WLAN uses DFS channels for critical traffic without recording how APs react to radar detection. Here the selected action should produce: Representative clients roam to the intended AP before experiencing excessive weak-link retransmissions.

Question 699

An engineer counts the advertised PHY rate as guaranteed application throughput for a Wi-Fi 6 workstation. The intended correction is: Separate negotiated PHY speed from MAC overhead, contention and usable application throughput. What evidence most clearly distinguishes success from a partial fix?

  1. Client wake-sleep and application delay measurements show the actual service impact of the configured schedule
  2. The new AP capability report confirms whether 6 GHz radios are physically present and enabled
  3. A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions
  4. Client retries and channel-busy metrics explain degradation even while HE capability is present

Explanation

Correct Answer

C:

A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions directly tests the proposed corrective action: Separate negotiated PHY speed from MAC overhead, contention and usable application throughput. 802.11 PHY capability is negotiated per client and is not conferred automatically by an AP marketing label.

Incorrect Answers

A:

That observation would confirm another situation: A router engineer claims that 802.11ax target wake time guarantees uninterrupted throughput for a latency-critical device. Here the selected action should produce: A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions.

B:

This check instead concerns a separate case: A network engineer replaces an 802.11ac AP with Wi-Fi 6 and expects the same device to advertise service on 6 GHz. Here the selected action should produce: A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions.

D:

That evidence would establish success in a different scenario: A dense lecture room has capable 802.11ax clients but WLAN users remain slow because all airtime is consumed by retransmissions. Here the selected action should produce: A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions.

Question 700

An engineer treats the security of a PSK WLAN as independent of whether every key is printed on the public site map. The selected operator action is: Protect PSK issuance and storage through approved secrets governance. Which outcome should the site engineer expect after the repair?

  1. A test credential successfully joins only the intended SSID or site
  2. An audit shows authorized recipients and no active WLAN keys in publicly accessible documents
  3. Testing shows network access follows key possession and separate human identity policy remains enforced
  4. The credential admits the device only into its approved restricted guest access class

Explanation

Correct Answer

B:

An audit shows authorized recipients and no active WLAN keys in publicly accessible documents directly tests the proposed corrective action: Protect PSK issuance and storage through approved secrets governance. Multiple-PSK designs can distinguish devices or groups only when credentials, scope, entitlements and network roles are governed.

Incorrect Answers

A:

This check instead concerns a separate case: A guest WLAN uses Cloud PSK credentials but the assigned password object is not mapped to any valid policy or site. Here the selected action should produce: An audit shows authorized recipients and no active WLAN keys in publicly accessible documents.

C:

That evidence would establish success in a different scenario: An engineer assumes using multiple PSKs automatically authenticates the named human operating any device even when a password is copied. Here the selected action should produce: An audit shows authorized recipients and no active WLAN keys in publicly accessible documents.

D:

That observation would confirm another situation: An administrator configures one PSK entry with an unrestricted default network role instead of the intended guest segment. Here the selected action should produce: An audit shows authorized recipients and no active WLAN keys in publicly accessible documents.
