1. 1When no known fingerprint matches a device, how does ClearPass Device Insight use machine learning?

   1. A.It groups unmatched devices using similar observed characteristicsCorrect answer: A
   2. B.It assigns every unmatched device to one known fingerprint
   3. C.It groups unmatched devices solely by an identical MAC address
   4. D.It waits for a known fingerprint before forming any groups

   Explanation: "If there is no match, machine learning models are used to group unknown devices that exhibit similar characteristics." The model groups similar unknown devices; it does not require an existing fingerprint match or group them solely by identical MAC address.

2. 2How does AOS-CX TACACS+ command authorization decide whether an authenticated administrator can execute a CLI command?

   1. A.It sends the command to the TACACS+ server for approvalCorrect answer: A
   2. B.It checks only whether the user's login password is valid
   3. C.Ask TACACS+ only at login and execute later commands without checks
   4. D.It permits any command after the user's role is assigned

   Explanation: "Each command is sent to the TACACS+ server for approval, and the switch then allows/disallows command execution according to the server response." Command authorization is separate from login authentication and evaluates each CLI command against the server response.

3. 3In an ArubaOS 8 WLAN AAA profile, which role is selected for unauthenticated users?

   1. A.Initial roleCorrect answer: A
   2. B.802.1X authentication default role
   3. C.MAC authentication default role
   4. D.Server-derived role

   Explanation: "Click the Initial Role drop-down list and select a role for unauthenticated users." The initial role applies before authentication; the other role settings apply to specific authentication or derivation outcomes.

4. 4For AOS-CX MAC authentication, what does the switch send to the RADIUS server as the device's identifying credential?

   1. A.The device MAC addressCorrect answer: A
   2. B.The switch's management certificate
   3. C.The switch port's MAC address instead of the client device address
   4. D.The user's 802.1X password

   Explanation: "The RADIUS server uses the device MAC address as the user name and password" The endpoint's MAC address, not the switch port address or an 802.1X credential, is used as the MAC authentication identity.

5. 5Which function belongs to the SD-Branch Overlay Tunnel Orchestrator?

   1. A.Generate and manage IPsec tunnel configuration between devicesCorrect answer: A
   2. B.Distribute route prefixes instead of generating IPsec tunnel configuration
   3. C.Build IPsec tunnels without identifying WAN uplinks or their labels
   4. D.Use only static peer addresses and ignore interface uplink labels

   Explanation: "The Overlay Tunnel Orchestrator automatically generates and manages IPsec configuration between devices and identifies where devices should tunnel." The guide assigns routing distribution to the route orchestrator and describes use of uplink labels and interface addresses by the tunnel orchestrator.

6. 6What changes in Policy Manager 6.8.2 when Device Insight integration is enabled?

   1. A.Device Insight replaces Profiler for device discovery and classificationCorrect answer: A
   2. B.Profiler continues to classify devices and Device Insight is disabled
   3. C.Policy Manager stops collecting device information altogether
   4. D.All device classification must be entered manually

   Explanation: "Policy Manager seamlessly switches to using Device Insight instead of Profiler for all device discovery and classification functionality." The Policy Manager server also acts as a collector; discovery and classification move to Device Insight.

7. 7An administrator manually acknowledges a Classic Central Gateway IDS/IPS alert. What happens to the aggregated event count?

   1. A.It is not reset and aggregation continuesCorrect answer: A
   2. B.It is reset to zero for all gateways
   3. C.It is frozen until the gateway is restarted
   4. D.It is converted into the signature severity

   Explanation: "As manually acknowledging an alert does not reset the count data, the alert service continues to aggregate events." An alert can be raised again when the aggregated count meets the threshold.

8. 8An AOS-CX NAE rule has a condition but no action. What happens when its condition changes state?

   1. A.The rule does not generate an alert for that transitionCorrect answer: A
   2. B.The rule automatically creates a syslog action
   3. C.The condition alone always generates a default alert
   4. D.The rule invokes its clear action even though none is defined

   Explanation: "A rule that does not include actions do not generate an alert when a condition transitions to true or to false." A condition without an action does not generate an alert or automatically create an action.

9. 9A Device Insight device has conflicting fingerprints and an unexpected category transition. Which system tag identifies this case?

   1. A.Suspected TransitionCorrect answer: A
   2. B.Expected Transition
   3. C.Library Update Transition
   4. D.User Tag

   Explanation: "Suspected Transition: Devices where there is an unexpected classification change." The suspected tag identifies an unexpected transition; expected and library-update transitions have different conditions.

10. 10In Device Insight's Network Activity Sankey chart, what does the width of a line represent?

    1. A.The quantity of packets for the protocol or applicationCorrect answer: A
    2. B.The average packet size for the protocol or application
    3. C.The elapsed duration of the session in minutes
    4. D.The number of distinct client devices in the access role

    Explanation: "The width of the lines is proportional to the quantity of packets for each protocol or application." Line width reflects packet quantity, not average size, elapsed time or access-role membership.
