Q73. A company wants you to create a custom device fingerprint on CPPM with rules for profiling a group of specialized devices. What is one requirement?

Connecting a known device of this type and getting it discovered in CPPM’s Endpoints Repository.

Enabling HPE Aruba Networking ClearPass Device Insight integration with the correct Data Collector token.

Pre-defining the desired attributes and rules in an XML format file.

Disabling the “Automatically download Endpoint Profiler Fingerprints” feature in cluster-wide parameters.

* Custom Device Fingerprinting on CPPM:
* To create a custom fingerprint, you first need to connect a known device of that type to the network.
* CPPM will discover the device in its Endpoints Repository, allowing you to analyze its attributes (e.g., MAC OUI, DHCP options) and create custom profiling rules.
* Option Analysis:
* Option A: Correct. Discovering a known device in the Endpoints Repository is a prerequisite for creating accurate custom fingerprint rules.
* Option B: Incorrect. CPDI integration is not required for custom fingerprints on CPPM.
* Option C: Incorrect. XML rules are not pre-defined; they are created dynamically based on observed attributes.
* Option D: Incorrect. The “Automatically download Endpoint Profiler Fingerprints” setting is unrelated to custom profiling.

Q74. A company has HPE Aruba Networking APs running AOS-10 and managed by HPE Aruba Networking Central. The company also has AOS-CX switches. The security team wants you to capture traffic from a particular wireless client. You should capture this client’s traffic over a 15 minute time period and then send the traffic to them in a PCAP file.
What should you do?

Go to the client’s AP in HPE Aruba Networking Central. Use the “Security” page to run a packet capture.

Access the CLI for the client’s AP. Set up a mirroring session between its radio and a management station running Wireshark.

Access the CLI for the client’s AP’s switch. Set up a mirroring session between the AP’s port and a management station running Wireshark.

Go to that client in HPE Aruba Networking Central. Use the “Live Events” page to run a packet capture.

To capture traffic from a particular wireless client for a 15-minute period and then send the traffic in a PCAP file, you should go to the client’s AP in HPE Aruba Networking Central and use the “Security” page to run a packet capture. This method allows you to directly capture the client’s traffic from the AP managing the wireless connection, ensuring that you gather the relevant traffic data for analysis.
1.Centralized Management: HPE Aruba Networking Central provides a centralized interface for managing and monitoring APs, making it easy to initiate packet captures.
2.Security Page: The “Security” page in Aruba Central includes tools for running packet captures, allowing you to specify the duration and other parameters.
3.Ease of Use: This approach simplifies the process by using the built-in features of Aruba Central, avoiding the need for complex CLI commands or additional hardware.

Q75. A company is implementing a client-to-site VPN based on tunnel-mode IPsec.
Which devices are responsible for the IPsec encapsulation?

The remote clients and a gateway at the main site

Gateways at the remote clients’ locations and a gateway at the main site

The remote clients and devices accessed by the clients at the main site

Gateways at the remote clients’ locations and devices accessed by the clients at the main site

In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.
1.IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.
2.Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.
3.Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.
Reference: Aruba and general IPsec VPN configuration guides provide detailed information on setting up client-to-site VPNs, highlighting the roles of remote clients and gateways in IPsec encapsulation.

Q76. A company has Aruba APs that are controlled by Central and that implement WIDS. When you check WIDS events, you see a “detect valid SSID misuse” event. What can you interpret from this event, and what steps should you take?

Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat.

Admins have likely misconfigured SSID security settings on some of the company’s APs. You should have them check those settings.

Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event.

This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it.

The “Detect Valid SSID Misuse” event in Aruba’s Wireless Intrusion Detection System (WIDS) indicates that a valid SSID, associated with your network, is being broadcast from an unauthorized source. This scenario often signals a potential rogue access point attempting to deceive clients into connecting to it (e.g., for credential harvesting or man-in-the-middle attacks).
1. Explanation of Each Option
A: Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat:
* Incorrect:
* This event is not related to authentication failures by legitimate clients.
* Misconfigured authentication settings would lead to events like “authentication failures” or
“radius issues,” not “valid SSID misuse.”
B: Admins have likely misconfigured SSID security settings on some of the company’s APs. You should have them check those settings:
* Incorrect:
* This event refers to an external device broadcasting your SSID, not misconfiguration on the company’s authorized APs.
* WIDS differentiates between valid corporate APs and rogue APs.
C: Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event:
* Correct:
* This is the most likely cause of the “detect valid SSID misuse” event. A rogue AP broadcasting a corporate SSID could lure clients into connecting to it, exposing sensitive credentials or traffic.
* Immediate action includes:
* Using the radio information from the event logs to identify the rogue AP’s location.
* Physically locating and removing the rogue device.
* Strengthening WIPS/WIDS policies to prevent further misuse.
D: This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it:
* Incorrect:
* While false positives are possible, “valid SSID misuse” is a critical security event that should not be ignored.
* Delaying action increases the risk of successful attacks against your network.
2. Recommended Steps to Address the Event
* Review Event Logs:
* Gather details about the rogue AP, such as SSID, MAC address, channel, and signal strength.
* Locate the Rogue Device:
* Use the detecting AP’s radio information and signal strength to triangulate the rogue AP’s physical location.
* Respond to the Threat:
* Remove or disable the rogue device.
* Notify the security team for further investigation.
* Prevent Future Misuse:
* Strengthen security policies, such as enabling client whitelists or enhancing WIPS protection.

Q77. You are deploying a virtual Data Collector for use with HPE Aruba Networking ClearPass Device Insight (CPDI). You have identified VLAN 101 in the data center as the VLAN to which the Data Collector should connect to receive its IP address and connect to HPE Aruba Networking Central.
Which Data Collector virtual ports should you tell the virtual admins to connect to VLAN 101?

The one with the lowest MAC address

The one with the highest port ID

The one with the highest MAC address

The one with the lowest port ID

When deploying a virtual Data Collector for HPE Aruba Networking ClearPass Device Insight (CPDI), it is essential to ensure that the correct virtual port is connected to the designated VLAN. In this case, VLAN 101 is used to receive the IP address and connect to Aruba Central. The best practice is to use the virtual port with the lowest port ID. This is typically the primary port used for management and network connectivity in virtual environments, ensuring proper network integration and communication.
Reference: Aruba’s ClearPass Device Insight deployment guides and virtual appliance setup documentation provide detailed instructions on configuring network interfaces and VLAN assignments.

Q78. An admin has configured an AOS-CX switch with these settings:
port-access role employees
vlan access name employees
This switch is also configured with CPPM as its RADIUS server.
Which enforcement profile should you configure on CPPM to work with this configuration?

RADIUS Enforcement type with HPE-User-Role VSA set to “employees”

HPE Aruba Networking Downloadable Role Enforcement type with role name set to “employees”

HPE Aruba Networking Downloadable Role Enforcement type with gateway role name set to
“employees”

RADIUS Enforcement type with Aruba-User-Role VSA set to “employees”

To ensure that the AOS-CX switch properly assigns the “employees” role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to “employees”. This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the “employees” role.
Reference: Aruba’s ClearPass documentation and AOS-CX configuration guides detail the integration and configuration of RADIUS enforcement profiles using Aruba-User-Role VSAs for role-based access control.

Q79. A company wants you to integrate HPE Aruba Networking ClearPass Policy Manager (CPPM) with HPE Aruba Networking ClearPass Device Insight (CPDI).
What is one aspect of the integration that you should explain?

CPPM no longer supports any Device Profiler features and relies on CPDI for this profile information.

CPDI must be configured as an audit server on CPPM for the integration to be successful.

CPDI must have security analysis disabled on it for the integration to be successful.

CPPM can submit profile information to CPDI, but if CPDI derives a different classification, CPDI takes precedence.

When integrating ClearPass Policy Manager (CPPM) with ClearPass Device Insight (CPDI), it is important to understand how device profiling and classification work between the two solutions:
1. CPPM and CPDI Integration Overview
* CPPM is primarily used for access control and policy enforcement, while CPDI specializes in device profiling and classification through advanced analytics and machine learning.
* Integration allows CPPM to leverage CPDI’s enhanced profiling capabilities for more accurate device identification and policy enforcement.
2. Detailed Analysis of Each Option
A: CPPM no longer supports any Device Profiler features and relies on CPDI for this profile information:
* Incorrect: CPPM still supports its own basic device profiling features and can operate independently.
However, when integrated with CPDI, CPPM can use CPDI’s advanced profiling capabilities as a supplement.
B: CPDI must be configured as an audit server on CPPM for the integration to be successful:
* Incorrect: CPDI is not configured as an audit server on CPPM. Integration is achieved via API integration and communication between the two solutions, not through audit server settings.
C: CPDI must have security analysis disabled on it for the integration to be successful:
* Incorrect: Security analysis does not need to be disabled for integration. In fact, CPDI’s security analysis enhances the classification process by identifying anomalous behaviors.
D: CPPM can submit profile information to CPDI, but if CPDI derives a different classification, CPDI takes precedence:
* Correct:
* CPPM and CPDI exchange profile data, but CPDI has more advanced device classification capabilities due to its machine learning-based engine.
* When CPDI derives a different classification than CPPM, CPDI’s classification is considered more accurate and takes precedence.
* This ensures that policies are based on the most reliable device classification.

Q80. You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are running version 6.9.).
For which type of certificate is it recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?

HTTPS

Database

RADIUS/EAP

RadSec

When setting up a ClearPass cluster, it is critical to ensure secure communication between the cluster nodes and the client devices. For this purpose, certain certificates must be properly configured.
1. Why HTTPS Requires a CA-Signed Certificate?
* HTTPS communication is used for inter-cluster communication and for the web-based user interface that administrators use to manage the ClearPass cluster.
* Before joining the cluster, it is strongly recommended to install a CA-signed HTTPS certificate on the Subscriber to ensure secure communication and prevent warnings/errors due to untrusted certificates.
* Without a CA-signed certificate, the Subscriber might use a self-signed certificate, leading to security risks and lack of trust validation.
2. Analysis of Other Certificate Types
* B. Database:
* Incorrect: Database communications within ClearPass clusters are secured using internal certificates or keys. These are not user-facing and do not require a CA-signed certificate before joining the cluster.
* C. RADIUS/EAP:
* Incorrect: RADIUS/EAP certificates are important for client authentication, but they are not required on the Subscriber prior to cluster joining. These can be configured after the Subscriber is part of the cluster.
* D. RadSec:
* Incorrect: RadSec is an optional feature for secure RADIUS communication over TLS, and its certificate configuration is typically performed post-cluster setup.
Final Recommendation
To ensure secure cluster operations and seamless web-based management, a CA-signed HTTPS certificate should be installed on the Subscriber before it joins the ClearPass cluster.

Q81. An AOS-CX switch has been configured to implement UBT to a cluster of three HPE Aruba Networking gateways.
How does the switch determine to which gateways to tunnel UBT users’ traffic?

The switch tunnels all users’ traffic to the gateway configured as the primary gateway in the UBT zone, unless that gateway fails.

The switch tunnels each user’s traffic to the particular gateway assigned as that user’s active user designed gateway.

The switch load balances client traffic across the primary and standby gateway configured in the UBT zone.

The switch tunnels all users’ traffic to the gateway assigned as the switch’s active device designated gateway.

When an AOS-CX switch implements User-Based Tunneling (UBT) to a cluster of three HPE Aruba Networking gateways, the switch determines to which gateway to tunnel each user’s traffic based on the particular gateway assigned as that user’s active user designated gateway. This ensures that traffic is efficiently distributed and managed according to the designated gateway for each user.
1.User Designated Gateway: Each user’s traffic is tunneled to a specific gateway that has been designated for that user, ensuring efficient handling of traffic.
2.Traffic Distribution: This method allows for balanced distribution of user traffic across multiple gateways, enhancing network performance and reliability.
3.Gateway Assignment: The switch uses the assigned gateway for each user to determine the tunneling path, ensuring that traffic is directed to the appropriate gateway.

Q82. Admins have recently turned on Wireless IDS/IPS infrastructure detection at the high level on HPE Aruba Networking APs. When you check WIDS events, you see several RTS rate and CTS rate anomalies, which were triggered by neighboring APs.
What can you interpret from this event?

These neighboring APs are likely to be wireless clients that are inappropriately bridging their wired and wireless NICs; you should track down and remove them.

These neighboring APs might be hackers trying to launch a DoS, but are more likely operating normally; you should start by tuning the event thresholds.

These neighboring APs are actually rogue APs, and you should enable wireless tarpit containment on them.

These neighboring APs are actually rogue APs, and you should enable wireless de-authentication containment on them.

When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.
Reference: Aruba’s Wireless IDS/IPS configuration guides provide information on interpreting events, adjusting thresholds, and distinguishing between legitimate and malicious activities in a wireless network environment.

Q83. 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?

The Posture Compliance option in the Service tab

The Profile Endpoints option in the Service tab

The Use cached Roles and Posture attributes from previous sessions option in the Enforcement tab

The Audit End-host option in the Service tab

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.
Reference: Aruba ClearPass documentation and profiling guides detail the configuration and use of endpoint profiling to enhance access control and policy enforcement based on device categories.

Q84. A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. The company wants CPPM to control which commands managers are allowed to enter.
Which service must you add to the managers’ TACACS+ enforcement profile?

Cpass:HTTP

Shell

ARAP

Aruba:Common

To control which commands managers are allowed to execute on AOS-CX switches using ClearPass Policy Manager (CPPM) as a TACACS+ server, you must configure the Shell service in the TACACS+ enforcement profile. The Shell service provides the ability to define granular access controls for commands. It supports policy-driven command authorization, which is essential in controlling administrative tasks based on roles.
References
* Official HPE Aruba ClearPass documentation on TACACS+ integration and command authorization.
* Industry best practices for AAA (Authentication, Authorization, and Accounting) configuration in network security architectures.

Q85. 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?

As the trunk native VLAN on edge ports and the trunk native VLAN on the “voice” role

As a trunk allowed VLAN on edge ports and the trunk native VLAN in the “voice” role

As the trunk native VLAN in the “voice” role (and not in the edge port settings)

As the allowed trunk VLAN in the “voice” role (and not in the edge port settings)

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.

Q86. A company has a variety of HPE Aruba Networking solutions, including an HPE Aruba Networking infrastructure and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company passes traffic from the corporate LAN destined to the data center through a third-party SRX firewall. The company would like to further protect itself from internal threats.
What is one solution that you can recommend?

Have the third-party firewall send Syslogs to CPPM, which can work with network devices to lock internal attackers out of the network.

Use tunnel mode SSIDs and user-based tunneling (UBT) on AOS-CX switches to pass all internal traffic directly through the third-party firewall.

Add ClearPass Device Insight (CPDI) to the solution; integrate it with the third-party firewall to develop more complete device profiles.

Configure CPPM to poll the third-party firewall for a broad array of information about internal clients, such as profile and posture.

To further protect the company from internal threats, you can recommend having the third-party SRX firewall send Syslogs to HPE Aruba Networking ClearPass Policy Manager (CPPM). ClearPass can analyze these logs to detect potential security incidents and coordinate with network devices to respond to threats. By integrating Syslog data from the firewall, CPPM can identify malicious activities and take actions such as locking internal attackers out of the network or triggering specific security policies. This approach enhances the company’s internal threat detection and response capabilities.

Q87. Refer to the exhibit.

The exhibit shows a saved packet capture, which you have opened in Wireshark. You want to focus on the complete conversation between 10.1.70.90 and 10.1.79.11 that uses source port 5448.
What is a simple way to do this in Wireshark?

Apply a capture filter that selects for both the 10.1.70.90 and 10.1.79.11 IP addresses.

Click the Source column and then the Destination column to sort the packets into the desired order.

Apply a capture filter that selects for TCP port 5448.

Right-click one of the packets between those addresses and choose to follow the stream.

* Wireshark: Follow TCP Stream:
* Wireshark provides an intuitive feature to filter and display a complete TCP conversation.
* By right-clicking any packet within the conversation and selecting “Follow # TCP Stream”, Wireshark isolates and displays the entire conversation.
* This feature allows you to view the communication in a simplified, sequential manner, including requests and responses.
* Option Analysis:
* Option A: Incorrect. Capture filters only apply during packet capturing, not for analyzing already saved packet captures.
* Option B: Incorrect. Sorting packets helps with organizing data but does not isolate a complete conversation.
* Option C: Incorrect. A capture filter for TCP port 5448 would have to be applied before capturing; it does not work for saved data.
* Option D: Correct. Right-clicking a packet and choosing “Follow TCP Stream” is the simplest way to display the full conversation between 10.1.70.90 and 10.1.79.11 on port 5448.
Steps in Wireshark to Follow a TCP Stream:
* Locate any packet within the desired conversation (e.g., between 10.1.70.90 and 10.1.79.11 on TCP port 5448).
* Right-click on the packet.
* Choose “Follow” # “TCP Stream”.
* Wireshark will display the entire TCP conversation, including both directions of communication.
This feature is especially useful when troubleshooting or analyzing detailed interactions between hosts.
