HP Aruba Certified Network Security Associate Exam Sample Questions (Q126-Q131):

NEW QUESTION # 126
What is a guideline for deploying Aruba ClearPass Device Insight?

A. For companies with multiple sites, deploy a pair of Device Insight Collectors at the HQ or the central data center.
B. Configure remote mirroring on access layer Aruba switches, using Device Insight Analyzer as the destination IP.
C. Deploy a Device Insight Collector at every site in the corporate WAN to reduce the impact on WAN links.
D. Make sure that Aruba devices trust the root CA certificate for the ClearPass Device Insight Analyzer's HTTPS certificate.

Answer: A

Explanation:
For deploying Aruba ClearPass Device Insight effectively, especially in environments with multiple sites, it is recommended to deploy a pair of Device Insight Collectors at the headquarters or the central data center.
This deployment strategy helps in centralizing the data collection and analysis, which simplifies management and enhances performance by reducing the data load on the WAN links connecting different sites.
Centralizing the collectors at a major site or data center allows for better scalability and reliability of the network management system. This configuration also aids in achieving a more consistent and comprehensive monitoring and analysis of the devices across the network, ensuring that the security and management policies are uniformly applied. This recommendation is based on best practices for network architecture design, particularly those discussed in Aruba's deployment guides and network management strategies.

NEW QUESTION # 128
An organization has HPE Aruba Networking infrastructure, including AOS-CX switches and an AOS-8 mobility infrastructure with Mobility Controllers (MCs) and APs. Clients receive certificates from ClearPass Onboard. The infrastructure devices authenticate clients to ClearPass Policy Manager (CPPM). The company wants to start profiling clients to take their device type into account in their access rights.
What is a role that CPPM should play in this plan?

A. Assigning clients to their device categories
B. Enforcing access control decisions
C. Accepting and enforcing CoA messages
D. Helping to forward profiling information to the component responsible for profiling

Answer: A

Explanation:
HPE Aruba Networking ClearPass Policy Manager (CPPM) is a network access control (NAC) solution that provides device profiling, authentication, and policy enforcement. In this scenario, the company wants to profile clients to determine their device type and use that information to define access rights. Device profiling in ClearPass involves identifying and categorizing devices based on various attributes, such as DHCP fingerprints, HTTP User-Agent strings, or TCP fingerprinting, to assign them to specific device categories (e.g., Windows, macOS, IoT devices, etc.). These categories can then be used in policy decisions to grant or restrict access.
Option A, "Assigning clients to their device categories," directly aligns with ClearPass's role in device profiling. ClearPass collects profiling data from network devices (like APs, MCs, or switches) and uses its profiling engine to categorize devices. This categorization is a core function of ClearPass Device Insight, which is integrated into CPPM, and is used to build policies based on device type.
Option B, "Helping to forward profiling information to the component responsible for profiling," is incorrect because ClearPass itself is the component responsible for profiling. It doesn't forward data to another system for profiling; instead, it collects data (e.g., via DHCP snooping, HTTP headers, or mirrored traffic) and processes it internally.
Option C, "Accepting and enforcing CoA messages," refers to ClearPass's ability to send Change of Authorization (CoA) messages to network devices to dynamically change a client's access rights (e.g., reassign a role or disconnect a session). While CoA is part of ClearPass's enforcement capabilities, it is not directly related to the profiling process or categorizing devices.
Option D, "Enforcing access control decisions," is a broader function of ClearPass. While ClearPass does enforce access control decisions based on profiling data (e.g., by assigning roles or VLANs), the question specifically asks about its role in the profiling process, not the enforcement step that follows.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"ClearPass Policy Manager provides a mechanism to profile devices that connect to the network. Device profiling collects information about a device during its authentication or through network monitoring (e.g., DHCP, HTTP, or SNMP). The collected data is used to identify and categorize the device into a device category (e.g., Computer, Smartphone, Printer, etc.) and device family (e.g., Windows, Android, etc.). These categories can then be used in policy conditions to enforce access control." (Page 245, Device Profiling Section) Additionally, the ClearPass Device Insight Data Sheet notes:
"ClearPass Device Insight uses a combination of passive and active profiling techniques to identify and classify devices. It assigns devices to categories based on their attributes, enabling organizations to create granular access policies." (Page 2)

NEW QUESTION # 129
The monitoring admin has asked you to set up an AOS-CX switch to meet these criteria:
Send logs to a SIEM Syslog server at 10.4.13.15 at the standard TCP port (514) Send a log for all events at the "warning" level or above; do not send logs with a lower level than "warning" The switch did not have any "logging" configuration on it. You then entered this command:
AOS-CX(config)# logging 10.4.13.15 tcp vrf default
What should you do to finish configuring to the requirements?

A. Ask for the Syslog password and configure it on the switch.
B. Add logging categories at the global level.
C. Specify the "warning" severity level for the logging server.
D. Configure logging as a debug destination.

Answer: C

Explanation:
The task is to configure an AOS-CX switch to send logs to a SIEM Syslog server at IP address 10.4.13.15 using TCP port 514, with logs for events at the "warning" severity level or above (i.e., warning, error, critical, alert, emergency). The initial command entered is:
AOS-CX(config)# logging 10.4.13.15 tcp vrf default
This command configures the switch to send logs to the Syslog server at 10.4.13.15 using TCP (port 514 is the default for TCP Syslog unless specified otherwise) and the default VRF. However, this command alone does not specify the severity level of the logs to be sent, which is a requirement of the task.
Severity Level Configuration: AOS-CX switches allow you to specify the severity level for logs sent to a Syslog server. The severity levels, in increasing order of severity, are: debug, informational, notice, warning, error, critical, alert, and emergency. The requirement is to send logs at the "warning" level or above, meaning warning, error, critical, alert, and emergency logs should be sent, but debug, informational, and notice logs should not.
Option A, "Specify the 'warning' severity level for the logging server," is correct. To meet the requirement, you need to add the severity level to the logging configuration for the specific Syslog server. The command to do this is:
AOS-CX(config)# logging 10.4.13.15 severity warning
This command ensures that only logs with a severity of warning or higher are sent to the Syslog server at 10.4.13.15. Since the initial command already specified TCP and the default VRF, this additional command completes the configuration.
Option B, "Add logging categories at the global level," is incorrect. Logging categories (e.g., system, security, network) are used to filter logs based on the type of event, not the severity level. The requirement is about severity ("warning" or above), not specific categories, so this step is not necessary to meet the stated criteria.
Option C, "Ask for the Syslog password and configure it on the switch," is incorrect. Syslog servers typically do not require a password for receiving logs, and AOS-CX switches do not have a configuration option to specify a Syslog password. Authentication or encryption for Syslog (e.g., using TLS) is not mentioned in the requirements.
Option D, "Configure logging as a debug destination," is incorrect. Configuring a debug destination (e.g., using the debug command) is used to send debug-level logs to a destination (e.g., console, buffer, or Syslog), but the requirement is to send logs at the "warning" level or above, not debug-level logs. Additionally, the logging command already specifies the Syslog server as the destination.
The HPE Aruba Networking AOS-CX 10.12 System Management Guide states:
"To configure a Syslog server on an AOS-CX switch, use the logging <ip-address> [tcp | udp] [vrf <vrf-name>] command to specify the server's IP address, protocol, and VRF. To filter logs by severity, add the severity <level> option to the logging command. For example, logging 10.4.13.15 tcp severity warning sends logs with a severity of warning or higher (warning, error, critical, alert, emergency) to the Syslog server at 10.4.13.15 using TCP. The default port for TCP Syslog is 514." (Page 89, Syslog Configuration Section) Additionally, the guide notes:
"Severity levels for logging on AOS-CX switches are, in increasing order: debug, informational, notice, warning, error, critical, alert, emergency. Specifying a severity level of 'warning' ensures that only logs at that level or higher are sent to the configured destination." (Page 90, Logging Severity Levels Section)
