What can you do to support these requirements?
- A. Schedule periodic subnet scans of all client subnets on CPPM.
- B. Add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches.
- C. On the APs and switches, configure a redirect to ClearPass Guest in the role for devices being profiled.
- D. Configure mirror sessions on the APs and switches to copy client HTTP traffic to CPPM.
Answer: B
Explanation:
To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.
1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling.
2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser.
3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.

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 93% confidence, and it is based on 36 classified devices.
- B. The recommendation has 96% confidence, and it is based on 13 classified devices.
- C. The recommendation has 98% confidence, and it is based on 5 classified devices.
- D. The recommendation has 100% confidence, and it is based on 4 classified devices.
Answer: B
Explanation:
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. Redirecting compromised clients to a remediation server
- B. Checking whether a client has antivirus software as a condition for receiving access to resources
- C. Applying threat inspection to users when they access certain websites
- D. Integrating with HPE Aruba Networking ClearPass OnGuard
Answer: B
Explanation:
Comprehensive Detailed Explanation
A non-default device posture is applied in scenarios where specific checks on a device's compliance or security state (posture) are required to grant or deny access. The correct answer is:
* B. Checking whether a client has antivirus software as a condition for receiving access to resources.
* This use case explicitly requires device posture assessment, which involves evaluating the device for attributes like antivirus software, patch levels, or other compliance criteria.
* Non-default device posture rules are configured to assess these conditions and enforce the appropriate policy based on the device's state.
Other Options:
* A. Applying threat inspection: Threat inspection rules operate independently of device posture and apply based on traffic content, not device compliance.
* C. Redirecting compromised clients: This action is typically triggered based on a security event or threat detection, not directly related to device posture evaluation.
* D. Integrating with ClearPass OnGuard: While OnGuard can contribute to posture assessment, it does not require a non-default device posture in the SSE rule directly.

NEW QUESTION # 24 
All of the switches in the exhibit are AOS-CX switches.
What is the preferred configuration on Switch-2 for preventing rogue OSPF routers in this network?
- A. Configure OSPF authentication on VLANs 10-19 in password mode.
- B. Configure passive-interface as the OSPF default and disable OSPF passive on Lag 1.
- C. Configure OSPF authentication on Lag 1 in MD5 mode.
- D. Disable OSPF entirely on VLANs 10-19.
Answer: C
Explanation:
To prevent rogue OSPF routers in the network shown in the exhibit, the preferred configuration on Switch-2 is to configure OSPF authentication on Lag 1 in MD5 mode. This setup enhances security by ensuring that only routers with the correct MD5 authentication credentials can participate in the OSPF routing process. This method protects the OSPF sessions against unauthorized devices that might attempt to introduce rogue routing information into the network.
1.OSPF Authentication: Implementing MD5 authentication on Lag 1 ensures that OSPF updates are secured with a cryptographic hash. This prevents unauthorized OSPF routers from establishing peering sessions and injecting potentially malicious routing information.
2.Secure Communication: MD5 authentication provides a higher level of security compared to simple password authentication, as it uses a more robust hashing algorithm.
3.Applicability: Lag 1 is the primary link between Switch-1 and Switch-2, and securing this link helps protect the integrity of the OSPF routing domain.

NEW QUESTION # 26
A company wants to implement Virtual Network based Tunneling (VNBT) on a particular group of users and assign those users to an overlay network with VNI
3000.
Assume that an AOS-CX switch is already set up to:
. Implement 802.1X to HPE Aruba Networking ClearPass Policy Manager (CPPM)
. Participate in an EVPN VXLAN solution that includes VNI 3000
Which setting should you configure in the users' AOS-CX role to apply VNBT to them when they connect?
- A. Gateway zone set to "3000" with no gateway role set
- B. Gateway zone set to "vni-3000" with no gateway role set
- C. Access VLAN set to the VLAN mapped to VNI 3000
- D. Access VLAN ID set to "3000"
Answer: C
Explanation:
To apply Virtual Network based Tunneling (VNBT) to a particular group of users and assign them to an overlay network with VNI 3000, you should configure the users' AOS-CX role to set the Access VLAN to the VLAN mapped to VNI 3000. This ensures that when users connect, their traffic is tunneled through the specified VNI, integrating seamlessly with the EVPN VXLAN solution.
1.Access VLAN Configuration: Setting the Access VLAN to the VLAN mapped to VNI 3000 ensures that users' traffic is directed to the correct virtual network.
2.EVPN VXLAN Integration: This setup allows the AOS-CX switch to participate in the EVPN VXLAN solution, ensuring that user traffic is properly encapsulated and tunneled.
3.Role-Based Assignment: Configuring the role with the correct VLAN mapping ensures that users are dynamically assigned to the appropriate virtual network based on their role.
NEW QUESTION # 27
You manage AOS-10 APs with HPE Aruba Networking Central. A role is configured on these APs with the following rules:
* Allow UDP on port 67 to any destination
* Allow any to network 10.1.6.0/23
* Deny any to network 10.1.0.0/16 + log
* Deny any to network 10.0.0.0/8
* Allow any to any destination
You add this new rule immediately before rule 2:
Deny SSH to network 10.1.4.0/23 + denylist
What happens when a client assigned to this role sends SSH traffic to 10.1.11.42?
- A. The traffic is dropped (without any logging or further action against the client).
- B. The traffic is dropped, and the client is denylisted.
- C. The traffic is dropped and logged.
- D. The traffic is permitted.
Answer: D
Explanation:
Comprehensive Detailed Explanation
* Traffic Match Evaluation Order:
* The rules are processed in sequential order, and the first rule that matches is applied.
* The added rule only denies SSH traffic to 10.1.4.0/23. Since 10.1.11.42 is not within the 10.1.4.0
/23 subnet, this rule does not apply.
* Next Matching Rule:
* Rule 2 permits traffic to the 10.1.6.0/23 network, but this does not include 10.1.11.42.
* Rule 3 denies traffic to the broader 10.1.0.0/16 network and logs it. Since 10.1.11.42 falls under this range, this rule applies, and the traffic would be logged and dropped.
* Logging and Denylist Actions:
* The denylist action in the new rule only applies to SSH traffic to 10.1.4.0/23. Since the destination is outside that range, the denylist is not triggered.

NEW QUESTION # 28
You are setting up policy rules in HPE Aruba Networking SSE. You want to create a single rule that permits users in a particular user group to access multiple applications. What is an easy way to meet this need?
- A. Associate the applications directly with the IdP used to authenticate the users; choose any for the destination in the policy rule.
- B. Apply the same tag to the applications; select the tag as a destination in the policy rule.
- C. Select the applications within a non-default web profile; select that profile in the policy rule.
- D. Place all the applications in the same connector zone; select that zone as a destination in the policy rule.
Answer: B
Explanation:
* Tagging Applications: In HPE Aruba Networking SSE (Secure Service Edge), tagging is an efficient way to group multiple applications together for simplified management and rule creation.
* Tags can be applied to applications, and a single policy rule can be configured to use the tag as the destination.
* This eliminates the need to create multiple rules for each individual application, streamlining policy configuration.
* Option B: Correct. Applying the same tag to multiple applications allows you to select the tag as the destination in a single policy rule, meeting the requirement efficiently.
* Option A: Incorrect. Associating applications with the IdP and selecting "any" for the destination lacks granularity and security.
* Option C: Incorrect. Using connector zones is more appropriate for network-level segmentation rather than grouping application policies.
* Option D: Incorrect. Web profiles are generally used for web-based traffic policies, not for grouping applications in general.
NEW QUESTION # 29
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. Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.
- B. Deploy an NAE agent on the switches to monitor control plane policing (CoPP).
- C. Enabling debugging of security functions on the switches.
- D. Implement ARP inspection on all VLANs that support end-user devices.
Answer: B
Explanation:
Why Monitoring Control Plane Policing (CoPP) with an NAE Agent Is Effective for Detecting DoS Attacks
* Control Plane Policing (CoPP): AOS-CX switches use CoPP to protect the CPU from excessive traffic caused by DoS attacks (e.g., ARP floods, ICMP floods). CoPP enforces rate limits and drops malicious traffic at the control plane level.
* NAE (Network Analytics Engine) Agent:
* The NAE on AOS-CX switches can monitor CoPP counters in real time and trigger alerts if thresholds for certain traffic types (e.g., ICMP, ARP) are exceeded.
* Admins can use NAE to automate detection and respond faster to DoS attacks.
Analysis of Each Option
A: Deploy an NAE agent on the switches to monitor control plane policing (CoPP):
* Correct:
* NAE agents provide real-time visibility into CoPP behavior, helping detect DoS attacks more quickly.
* By analyzing CoPP statistics, the NAE can pinpoint abnormal traffic patterns and alert admins.
* This is the most efficient and scalable solution for this use case.
B: Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight:
* Incorrect:
* While ClearPass can provide visibility into user authentication and device activity, it is not specifically designed to detect or mitigate DoS attacks against switches.
C: Implement ARP inspection on all VLANs that support end-user devices:
* Incorrect:
* ARP inspection helps mitigate ARP spoofing or poisoning, but it does not directly address detection of DoS attacks like ICMP or ARP floods.
* It is a preventative measure, not a detection tool.
D: Enabling debugging of security functions on the switches:
* Incorrect:
* Debugging logs can help troubleshoot specific issues but are not practical for real-time detection of DoS attacks.
* Enabling debugging can overload the switch and is not suitable for proactive monitoring.
Final Recommendation
Deploying an NAE agent to monitor CoPP is the best solution because it provides real-time detection, alerting, and insights into traffic patterns that indicate DoS attacks.

NEW QUESTION # 30
You are using Wireshark to view packets captured from HPE Aruba Networking infrastructure, but you're not sure that the packets are displaying correctly. In which circumstance does it make sense to configure Wireshark to ignore protection bits with the IV for the 802.11 protocol?
- A. When the traffic was captured from an AP with HPE Aruba Networking Central.
- B. When the traffic was captured on the control plane of an HPE Aruba Networking MC and sent to a remote IP.
- C. When the traffic was mirrored from an AOS-CX switch port connected to an AP.
- D. When the traffic was captured on the data plane of an HPE Aruba Networking gateway and sent to a remote IP.
Answer: A
Explanation:
* 802.11 Traffic and Protection Bits:
* In the 802.11 protocol, protection bits and the Initialization Vector (IV) are used in encrypted wireless traffic.
* If the traffic is captured directly from an AP, the frames may include encrypted content.
* Wireshark may misinterpret these protection bits or fail to display the frames correctly unless it is configured to ignore protection bits and correctly parse the IV.
* Key Scenario:
* When traffic is captured directly from an AP managed by HPE Aruba Networking Central, the frames are often captured before decryption occurs.
* In such cases, you must configure Wireshark to ignore the protection bits and handle the IV properly for correct frame interpretation.
* Option Analysis:
* Option A: Incorrect. Data plane traffic sent to a remote IP is usually decrypted, so Wireshark does not require this adjustment.
* Option B: Incorrect. Switch port mirroring captures traffic at Layer 2/3, not raw 802.11 frames.
* Option C: Correct. Traffic captured directly from an AP via HPE Aruba Networking Central often includes encrypted wireless frames, requiring Wireshark adjustments.
* Option D: Incorrect. Control plane traffic is typically management data and not raw wireless frames needing IV interpretation.
NEW QUESTION # 31
A company has HPE Aruba Networking infrastructure devices. The devices authenticate clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). You want CPPM to track information about clients, such as their IP addresses and their network bandwidth utilization. What should you set up on the network infrastructure devices to help that happen?
- A. Dynamic authorization enabled in the RADIUS settings for CPPM.
- B. Logging with CPPM configured as a Syslog server.
- C. An IF-MAP interface with CPPM as the destination.
- D. RADIUS accounting to CPPM, including interim updates.
Answer: D
Explanation:
* RADIUS Accounting:
* RADIUS accounting enables network devices to report client session details (e.g., IP addresses, session duration, bandwidth usage) to CPPM.
* Interim updates ensure CPPM receives ongoing updates about the client's session, enabling accurate tracking.
* Option Analysis:
* Option A: Incorrect. Syslog logging sends general system logs, not client session details.
* Option B: Incorrect. Dynamic authorization (CoA) handles session changes but does not provide usage tracking.
* Option C: Correct. RADIUS accounting with interim updates tracks client IP addresses and bandwidth utilization.
* Option D: Incorrect. IF-MAP interfaces are used for metadata sharing, not for RADIUS-based tracking.
NEW QUESTION # 32
A company has several use cases for using its AOS-CX switches' HPE Aruba Networking Network Analytics Engine (NAE).
What is one guideline to keep in mind as you plan?
- A. Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
- B. You can install multiple scripts on a switch, but you can deploy only one agent per script.
- C. When you use custom scripts, you can create as many agents from each script as you want.
- D. The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
Answer: A
Explanation:
The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here's an analysis of the guidelines for NAE:
A: Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.
* Correct:
* Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.
* Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.
* Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.
* Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.
B: You can install multiple scripts on a switch, but you can deploy only one agent per script.
* Incorrect:
* Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.
* The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.
C: The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
* Incorrect:
* AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.
* You cannot deploy an unlimited number of agents, as the system enforces these restrictions.
D: When you use custom scripts, you can create as many agents from each script as you want.
* Incorrect:
* While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.
* The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

- C. The posture is unhealthy, but CPDI has not detected any vulnerabilities on the device.
- D. The posture is unhealthy, and CPDI has also detected at least one vulnerability on the device.
Answer: D
Explanation:
In HPE Aruba Networking ClearPass Device Insight (CPDI), a device with a Risk Score of 90 indicates that the posture is unhealthy, and CPDI has detected at least one vulnerability on the device. The risk score is a reflection of the device's security posture and detected vulnerabilities. A high risk score, such as 90, typically signifies significant security concerns, including the presence of vulnerabilities that could be exploited, thereby categorizing the device as a high-risk asset within the network.
NEW QUESTION # 34
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. Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port.
- B. Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture.
- C. Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port.
- 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.
Answer: D
Explanation:
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.

NEW QUESTION # 35
You have configured an AOS-CX switch to implement 802.1X on edge ports. Assume ports operate in the default auth-mode. VolP phones are assigned to the
"voice" role and need to send traffic that is tagged for VLAN 12.
Where should you configure VLAN 12?
- A. As the trunk native VLAN on edge ports and the trunk native VLAN on the "voice" role
- B. As the allowed trunk VLAN in the "voice" role (and not in the edge port settings)
- C. As the trunk native VLAN in the "voice" role (and not in the edge port settings)
- D. As a trunk allowed VLAN on edge ports and the trunk native VLAN in the "voice" role
Answer: B
Explanation:
When configuring 802.1X authentication on edge ports of an AOS-CX switch and assigning VoIP phones to a
"voice" role, the correct approach is to configure VLAN 12 as the allowed trunk VLAN in the "voice" role.
This setup ensures that traffic tagged for VLAN 12 is appropriately managed by the role applied to the VoIP phones. In AOS-CX switches, the role-based VLAN configuration allows for more granular control and ensures that the VoIP phones' traffic is handled correctly without altering the edge port settings, which typically operate with default settings for authentication.
NEW QUESTION # 36
