HPE Aruba Networking ClearPass Device Insight (CPDI) could not classify some endpoints using system and user rules. Using machine learning, it did assign those endpoints to a cluster and discover a recommendation.
In which of these circumstances does CPDI automatically classify the endpoints based on that recommendation?
- A. The recommendation has 98% confidence, and it is based on 5 classified devices.
- B. The recommendation has 96% confidence, and it is based on 13 classified devices.
- C. The recommendation has 93% confidence, and it is based on 36 classified devices.
- D. The recommendation has 100% confidence, and it is based on 4 classified devices.
正解：B
解説：
Comprehensive Detailed Explanation
HPE Aruba Networking ClearPass Device Insight (CPDI) uses machine learning to assign endpoints to clusters and provide classification recommendations. For CPDI to automatically classify endpoints, specific thresholds of confidence and supporting classified devices must be met.
The generally required thresholds are:
* Minimum Confidence Level: Typically, CPDI requires a recommendation confidence level of at least
95%.
* Minimum Supporting Devices: CPDI needs a cluster to include at least 10 classified devices to ensure the recommendation is statistically meaningful.
Analysis of Each Option:
* A. 96% confidence with 13 classified devices: Meets both thresholds (confidence > 95% and # 10 devices). CPDI will automatically classify endpoints in this scenario.
* B. 98% confidence with 5 classified devices: Confidence level is sufficient, but the cluster lacks the minimum required 10 classified devices. Automatic classification does not occur.
* C. 93% confidence with 36 classified devices: The confidence level is below the required 95%.
Automatic classification does not occur.
* D. 100% confidence with 4 classified devices: Confidence is ideal, but there are insufficient supporting classified devices. Automatic classification does not occur.

A company has AOS-CX switches. The company wants to make it simpler and faster for admins to detect denial of service (DoS) attacks, such as ping or ARP floods, launched against the switches.
What can you do to support this use case?
- A. Deploy an NAE agent on the switches to monitor control plane policing (CoPP).
- B. Enabling debugging of security functions on the switches.
- C. Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.
- D. Implement ARP inspection on all VLANs that support end-user devices.
正解：A
解説：
To support the detection of denial of service (DoS) attacks on AOS-CX switches, deploying an NAE (Network Analytics Engine) agent to monitor control plane policing (CoPP) is the best approach.NAE agents provide real-time analytics and monitoring capabilities, allowing administrators to detect anomalies and potential DoS attacks, such as ping or ARP floods, more quickly and efficiently. Control plane policing helps protect the switch's CPU from unnecessary or malicious traffic, and the NAE agent can alert administrators when thresholds are exceeded, providing a proactive measure to detect and mitigate DoS attacks.
質問 # 55
An AOS-CX switch has this admin user account configured on it:
netadmin in the operators group.
You have configured these commands on an AOS-CX switch:
tacacs-server host cp.example.com key plaintext &12xl,powmay7855
aaa authentication login ssh group tacacs local
aaa authentication allow-fail-through
A user accesses the switch with SSH and logs in as netadmin with the correct password. When the switch sends a TACACS+ request to the ClearPass server at cp.example.com, the server does not send a response.
Authentication times out.
What happens?
- A. The user is logged in and granted administrators access.
- B. The user is logged in and allowed to enter auditor commands only.
- C. The user is not allowed to log in.
- D. The user is logged in and granted operator access.
正解：D
解説：
Comprehensive Detailed Explanation
The configuration includes the command aaa authentication allow-fail-through, which specifies that if the TACACS+ server fails to respond (e.g., times out), the switch will proceed to the next authentication method in the sequence, which is local. In this scenario:
* The switch first attempts to authenticate the user against the TACACS+ server.
* When the TACACS+ server fails to respond, the switch falls back to local authentication.
* The user netadmin is a local account configured on the switch and belongs to the operators group.
* As a result, the user is successfully authenticated locally and is granted operator level access.

質問 # 56
A port-access role for AOS-CX switches has this policy applied to it:
plaintext
Copy code
port-access policy mypolicy
10 class ip zoneC action drop
20 class ip zoneA action drop
100 class ip zoneB
The classes have this configuration:
plaintext
Copy code
class ip zoneC
10 match tcp 10.2.0.0/16 eq https
class ip zoneA
10 match ip any 10.1.0.0/16
class ip zoneB
10 match ip any 10.0.0.0/8
The company wants to permit clients in this role to access 10.2.12.0/24 with HTTPS. What should you do?
- A. Add this rule to zoneC: 5 match any 10.2.12.0/24 eq https
- B. Add this rule to zoneB: 5 match tcp any 10.2.12.0/24 eq https
- C. Add this rule to zoneC: 5 ignore tcp any 10.2.12.0/24 eq https
- D. Add this rule to zoneA: 5 ignore tcp any 10.2.12.0/24 eq https
正解：A
解説：
Comprehensive Detailed Explanation
* The requirement is to permit HTTPS traffic from clients to the 10.2.12.0/24 subnet.
* ZoneC is configured to drop all HTTPS traffic to the 10.2.0.0/16 subnet. Therefore, the first match in the zoneC class (priority 10) will drop the desired traffic.
* To override this behavior, you must add a higher-priority rule (lower rule number) to zoneC that explicitly matches 10.2.12.0/24 and permits the traffic.
Thus, adding the rule 5 match any 10.2.12.0/24 eq https to zoneC ensures the desired traffic is permitted while maintaining the drop behavior for the rest of 10.2.0.0/16.

質問 # 58
A company has HPE Aruba Networking APs managed by HPE Aruba Networking Central. You have set up a WLAN to enforce WPA3 with 802.1X authentication.
What happens if the client fails authentication?
- A. The AP assigns the client to the WLAN's initial role.
- B. The AP assigns the client to the WLAN's critical role.
- C. The AP assigns the client to the WLAN's default role.
- D. The AP drops the client because authentication aborts.
正解：D
解説：
When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:
1. 802.1X Authentication Workflow in WPA3
* The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.
* If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the
802.1X handshake fails, and the AP terminates the connection.
2. Role Assignment in WLANs
* Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.
* Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.
* Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.
3. Behavior Upon Authentication Failure
* In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.
* The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.
Explanation of Each Option
* A. The AP assigns the client to the WLAN's default role:
* Incorrect: The default role applies only after successful authentication, not in case of authentication failure.
* B. The AP drops the client because authentication aborts:
* Correct: If the client fails authentication, the AP terminates the connection without assigning any roles.
* C. The AP assigns the client to the WLAN's critical role:
* Incorrect: The critical role is used when the AP cannot reach the RADIUS server, not when authentication fails.
* D. The AP assigns the client to the WLAN's initial role:
* Incorrect: The initial role is applied during the authentication process, but it is not retained after a failed authentication.

- C. Having switches download user-roles from HPE Aruba Networking gateways
- D. Having HPE Aruba Networking ClearPass Policy Manager (CPPM) send standard RADIUS AVPs to customize port settings
正解：A
解説：
For a company that wants to apply a standard configuration to all AOS-CX switch ports and dynamically adjust their configuration based on the identity of the user or device that connects, the best approach is to have the switches download user-roles from HPE Aruba Networking ClearPass Policy Manager (CPPM).
This method centralizes the configuration of identity-based settings in CPPM, allowing it to dynamically assign roles and policies to switch ports based on authentication and authorization results. This ensures consistent and secure network access control tailored to each user or device.
質問 # 60
A company has AOS-CX switches at the access layer, managed by HPE Aruba Networking Central. You have identified suspicious activity on a wired client. You want to analyze the client's traffic with Wireshark, which you have on your management station.
What should you do?
- A. Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination.
- B. Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port.
- C. Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture.
- D. Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port.
正解：A
解説：
Why a Mirror Session Is the Correct Choice
To analyze a wired client's traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.
Analysis of Each Option
A: Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:
* Incorrect:
* AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.
* This approach is not feasible for capturing and analyzing live client traffic.
B: Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture:
* Incorrect:
* HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.
* Traffic analysis with tools like Wireshark requires local packet capture at the management station.
C: Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:
* Incorrect:
* Captive portals are designed for user authentication and redirection, not traffic analysis.
* This would disrupt the client's network activity without enabling traffic analysis in Wireshark.
D: Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:
* Correct:
* Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.
* Steps include:
* Configure a mirror session on the client's AOS-CX switch.
* Set the client's port as the source.
* Set your management station as the destination using its IP address (via GRE tunnel or physical interface).
* Start capturing traffic with Wireshark on the management station.
Final Recommendation
To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.

HPE Aruba Networking ClearPass Policy Manager (CPPM) uses a service to authenticate clients. You are now adding the Endpoints Repository as an authorization source for the service, and you want to add rules to the service's policies that apply different access levels based, in part, on a client's device category. You need to ensure that CPPM can apply the new correct access level after discovering new clients' categories.
What should you enable on the service?
- A. The Audit End-host option in the Service tab
- B. The Use cached Roles and Posture attributes from previous sessions option in the Enforcement tab
- C. The Posture Compliance option in the Service tab
- D. The Profile Endpoints option in the Service tab
正解：D
解説：
To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) can apply the correct access levels based on a client's device category after discovering new clients, you need to enable the "Profile Endpoints" option in the Service tab. This option allows CPPM to profile and categorize endpoints dynamically, ensuring that the appropriate access levels are applied based on the device's characteristics.
Enabling this feature ensures that new devices are accurately profiled and that access policies can be enforced based on the updated device information.
質問 # 62
You are configuring the HPE Aruba Networking ClearPass Device Insight Integration settings on ClearPass Policy Manager (CPPM). For which use case should you set the 'Tag Updates Action" to " apply for all tag updates"?
- A. When you plan to have CPPM issue CoAs for clients with new tags, but do not want to have to list those specific tags in the Device Integration settings in advance.
- B. When CPPM is gathering posture information for CPDI, and you want CPDI to always have access to the most up-to-date information.
- C. When Device Insight tags are only used to identify dangerous devices, and you want to disconnect those devices without having to set up new rules in enforcement policies.
- D. When the Device Insight integration poll interval is set to a relatively long interval but you still want CPPM to be informed quickly about devices' new tags.
正解：A
解説：
* Tag Updates Action - "Apply for All Tag Updates":
* This setting ensures that all updated tags from Device Insight (CPDI) are applied dynamically.
* It is particularly useful when you want to trigger Change of Authorization (CoA) without explicitly predefining the tag values.
* Option D: Correct. This setting allows CPPM to issue CoAs automatically for updated tags without requiring prior configuration of specific tags.
* Option A: Incorrect. The setting is not directly related to reducing the poll interval latency.
* Option B: Incorrect. Disconnecting devices based on dangerous tags would require predefined enforcement rules.
* Option C: Incorrect. Posture information updates do not directly rely on this setting.
質問 # 63
You are setting up user-based tunneling (UBT) between access layer AOS-CX switches and AOS-10 gateways. You have selected reserved (local) VLAN mode.
Tunneled devices include IoT devices, which should be assigned to:
* Roles: iot on the switches and iot-wired on the gateways
* VLAN: 64, for which the gateways route traffic.
IoT devices connect to the access layer switches' edge ports, and the access layer switches reach the gateways on their uplinks.
Where must you configure VLAN 64?
- A. In the iot-wired role and on no physical interfaces
- B. In the iot-wired role and the access switch uplinks
- C. In the iot role and the access switch uplinks
- D. In the iot role and the iot-wired role and on no physical interfaces
正解：A
解説：
Comprehensive Detailed Explanation
In a user-based tunneling (UBT) setup with reserved VLAN mode, VLAN 64 is used for routing traffic at the gateways. Since the IoT traffic is tunneled to the AOS-10 gateway:
* On the gateways:
* VLAN 64 must be configured in the iot-wired role for routing purposes.
* On the switches:
* VLAN 64 does not need to be configured on the access switch physical uplinks because the IoT traffic is tunneled directly to the gateway and does not rely on VLAN configurations at the access layer switches.
* Reserved VLAN mode:
* Ensures that traffic is encapsulated within the UBT tunnel, and VLANs like 64 are only relevant at the gateway for routing and enforcement.
Therefore, the correct configuration is to define VLAN 64 in the iot-wired role on the AOS-10 gateways and not on any physical interfaces.

- B. The Check Point Extension is installed through ClearPass Guest.
- C. Ingress Event Dictionaries for Check Point messages are enabled.
- D. The CoA delay value is set to 0 on the server.
正解：C
解説：
To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) responds correctly to Syslog messages from a Check Point firewall, you need to check that the Ingress Event Dictionaries for Check Point messages are enabled. These dictionaries are necessary for CPPM to properly interpret and respond to the Syslog messages received from the firewall.
1.Event Dictionaries: Ingress Event Dictionaries allow CPPM to understand the specific format and content of Syslog messages from various sources, such as Check Point firewalls.
2.Message Interpretation: Without these dictionaries enabled, CPPM may not correctly interpret the Syslog messages, leading to a failure in triggering the expected actions.
3.Configuration Check: Ensuring that the dictionaries are enabled is crucial for the proper functioning of the event service and accurate response to security events.
質問 # 66
Refer to Exhibit:
An HPE Aruba Networking 9x00 gateway is part of an HPE Aruba Networking Central group that has the settings shown in the exhibit. What would cause the gateway to drop traffic as part of its IDPS settings?
- A. Its site-to-site VPN connections failing
- B. Its IDPS engine failing
- C. Traffic showing anomalous behavior
- D. Traffic matching a rule in the active ruleset
正解：D
解説：
1. IDPS Mode Configuration Overview
The exhibit shows the HPE Aruba Networking Central settings for the Gateway IDS/IPS configuration:
* Mode: Configured for Intrusion Prevention System (IPS), meaning that the gateway actively blocks traffic identified as threats.
* Fail Strategy: Configured to Block, meaning that if the gateway cannot determine the traffic's nature due to a system issue, it will block the traffic.
* Ruleset: The gateway uses a predefined set of intrusion detection/prevention rules (ruleset version
9861), which is updated automatically every day.
2. Traffic Evaluation in IPS Mode
In IPS mode, the gateway analyzes traffic against the active ruleset:
* If traffic matches a rule in the ruleset and is deemed malicious, the gateway will drop the traffic as part of its prevention mechanism.
* The ruleset defines specific conditions (e.g., signatures of known attacks, protocol anomalies) under which traffic should be blocked.
3. Explanation of Each Option
* A. Its site-to-site VPN connections failing:
* Incorrect:
* Site-to-site VPN connection issues do not directly trigger traffic drops under IDPS settings.
* IDPS is focused on detecting and preventing malicious activity, not general connectivity issues.
* B. Traffic matching a rule in the active ruleset:
* Correct:
* In IPS mode, the gateway drops traffic that matches any predefined rules in the active ruleset.
* For example, if traffic matches the signature of a known exploit or attack, it is immediately blocked.
* C. Its IDPS engine failing:
* Incorrect:
* The fail strategy determines how the gateway behaves in the event of an IDPS engine failure.
* In this case, the fail strategy is set to Block, but this applies only if the engine itself fails, not as a proactive traffic drop mechanism.
* D. Traffic showing anomalous behavior:
* Incorrect:
* While anomalous behavior may be logged or flagged, it does not necessarily lead to traffic drops unless it matches a specific rule in the active ruleset.
* Anomaly detection alone is not sufficient for IPS action without explicit rule matches.
Final Outcome:
Traffic is dropped only when it matches a rule in the active ruleset, ensuring targeted prevention of malicious activity.
