  Explanation

  Integration of CPDI and CPPM for Zero Trust:

  CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.

  tag devices based on their behavior or detected applications.

  CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).

  Option Analysis:

  Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.

  Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.

  Option C: Incorrect. Custom fingerprint definitions are not part of this integration.

  Option D: Incorrect. CPDI provides information about devices, not user identities.

• Question 32:

  The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?

  

  A. Specify at least two server names under the "Connect to these servers" field.
  B. Select the desired Trusted Root Certificate Authority and select the check box next to "Don't prompt users."
  C. Under the "Connect to these servers" field, use a wildcard in the server name.
  D. Clear the check box for using simple certificate selection and select the desired certificate manually.
  A. Specify at least two server names under the "Connect to these servers" field.

  ---

  Explanation

  To follow best security practices for 802.1X authentication settings in Windows domain clients:

  Specify at least two server names under "Connect to these servers":

  Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.

  This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.

  Select the desired Trusted Root Certificate Authority and "Don't prompt users":

  Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.

  Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.

  Why the other options are incorrect:

  Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.

  Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.

  Recommended Settings for Best Security Practices:

  Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.

  User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.

• Question 33:

  For which type of certificate it is recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?

  A. Database
  B. HTTPS
  C. RADIUS/EAP
  D. RadSec
  B. HTTPS

  ---

  Explanation

  When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA- signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in

  the cluster and provides a trusted certificate for client connections.

  1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.

  2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.

  3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.

• Question 34:

  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?

  A. Connecting a known device of this type and getting it discovered in CPPM's Endpoints Repository.
  B. Enabling HPE Aruba Networking ClearPass Device Insight integration with the correct Data Collector token.
  C. Pre-defining the desired attributes and rules in an XML format file.
  D. Disabling the "Automatically download Endpoint Profiler Fingerprints" feature in cluster-wide parameters.
  A. Connecting a known device of this type and getting it discovered in CPPM's Endpoints Repository.

  ---

  Explanation

  Custom Device Fingerprinting on CPPM:

  known device of that type to the To create a custom fingerprint, you first need to connect a 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.

• Question 35:

  A company has AOS-CX switches and HPE Aruba Networking APs, which run AOS-10 and bridge their SSIDs. Company security policies require 802.1X on all edge ports, some of which connect to APs. How should you configure the authmode on AOS-CX switches?

  A. Leave all edge ports in client auth-mode and configure device auth-mode in the AP role.
  B. Configure all edge ports in client auth-mode.
  C. Configure all edge ports in device auth-mode.
  D. Leave all edge ports in device auth-mode and configure client auth-mode in the AP role.
  A. Leave all edge ports in client auth-mode and configure device auth-mode in the AP role.

  ---

  Explanation

  802.1X Authentication Modes:

  Client Auth-Mode: Requires each connected endpoint to authenticate individually using 802.1X.

  Device Auth-Mode: Allows the port to authenticate a device, such as an AP, as a whole. This mode works when the device bridges traffic (e.g., AP bridging SSID traffic).

  AP Role Configuration:

  Since the AP bridges traffic from multiple clients, you must configure the AP role to use device auth-mode.

  Meanwhile, the ports on edge switches can remain in client auth-mode to enforce 802.1X for individual client connections.

  Option Analysis:

  Option A: Correct. This ensures the AP itself authenticates with device auth-mode, while edge ports remain in client auth-mode.

  Option B: Incorrect. APs require device auth-mode for bridging, not client auth-mode.

  Option C: Incorrect. Device auth-mode on all ports would not meet the security policy for clients.

  Option D: Incorrect. Leaving all ports in device auth-mode does not meet the policy for 802.1X on edge ports.

• Question 36:

  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. Logging with CPPM configured as a Syslog server.
  B. Dynamic authorization enabled in the RADIUS settings for CPPM.
  C. RADIUS accounting to CPPM, including interim updates.
  D. An IF-MAP interface with CPPM as the destination.
  C. RADIUS accounting to CPPM, including interim updates.

  ---

  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.

  C. Configure WMI, SSH, and SNMP external accounts for device scanning on CPPM.
  D. Collect a Data Collector token from HPE Aruba Networking Central.
  B. Enable Insight in the CPPM server configuration settings.

  ---

  Explanation

  ClearPass Device Insight Integration:

  To integrate ClearPass Device Insight (CPDI) with ClearPass Policy Manager (CPPM), you must enable the Insight feature in the CPPM server configuration settings.

  This ensures CPPM can share and receive profiling data with CPDI for device identification.

  Option Analysis:

  Option A: Incorrect. Root CA certificates are not required for this integration.

  Option B: Correct. Enabling Insight on CPPM is essential for the integration to function.

  Option C: Incorrect. WMI, SSH, and SNMP are not part of the CPDI integration prerequisites.

  Option D: Incorrect. The Data Collector token is relevant to Aruba Central, not CPDI integration.

• Question 39:

  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?

  A. HTTPS
  B. Database
  C. RADIUS/EAP
  D. RadSec
  A. HTTPS

  ---

  Explanation

  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

  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.

• Question 40:

  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. Implement ARP inspection on all VLANs that support end-user devices.
  C. Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.
  D. Enabling debugging of security functions on the switches.
  A. Deploy an NAE agent on the switches to monitor control plane policing (CoPP).

  ---

  Explanation

  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.
