HP Aruba Certified Network Security Associate Exam Sample Questions (Q148-Q153):

NEW QUESTION # 148
What is one way that Control Plane Security (CPSec) enhances security for the network?

  • A. It protects wireless clients' traffic, tunneled between APs and Mobility Controllers, from eavesdropping.
  • B. It protects management traffic between APs and Mobility Controllers (MCs) from eavesdropping.
  • C. It prevents Denial of Service (DoS) attacks against Mobility Controllers' (MCs') control plane.
  • D. It prevents access from unauthorized IP addresses to critical services, such as SSH, on Mobility Controllers (MCs).

Answer: B

Explanation:
Control Plane Security (CPSec) is a feature in HPE Aruba Networking's AOS-8 architecture that secures the communication between Access Points (APs) and Mobility Controllers (MCs). The control plane includes management traffic, such as AP registration, configuration updates, and heartbeat messages, which are critical for the operation of the wireless network.
Option A, "It protects management traffic between APs and Mobility Controllers (MCs) from eavesdropping," is correct. CPSec uses certificate-based authentication and encryption (IPSec tunnels) to secure the control plane communication between APs and MCs. This ensures that management traffic, which includes sensitive information like configuration data and AP status, is encrypted and protected from eavesdropping by unauthorized parties on the network.
Option B, "It prevents Denial of Service (DoS) attacks against Mobility Controllers' (MCs') control plane," is incorrect. While CPSec enhances security by authenticating APs and encrypting traffic, it is not specifically designed to prevent DoS attacks. DoS attacks against the control plane are mitigated by other features, such as rate limiting or firewall policies on the MC.
Option C, "It protects wireless clients' traffic, tunneled between APs and Mobility Controllers, from eavesdropping," is incorrect. CPSec protects the control plane (management traffic), not the data plane (client traffic). Client traffic in a tunneled architecture (e.g., GRE tunnels) is protected by the client's wireless encryption (e.g., WPA3), not CPSec.
Option D, "It prevents access from unauthorized IP addresses to critical services, such as SSH, on Mobility Controllers (MCs)," is incorrect. CPSec does not control access to services like SSH on the MC. Access to such services is managed by other features, such as access control lists (ACLs) or management authentication settings on the MC.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Control Plane Security (CPSec) enhances network security by protecting the management traffic between Access Points (APs) and Mobility Controllers (MCs). When CPSec is enabled, the control plane communication is secured using certificate-based authentication and IPSec encryption, preventing eavesdropping and ensuring that only authorized APs can communicate with the MC. This protects sensitive management data, such as AP configuration and status updates, from being intercepted." (Page 392, CPSec Overview Section) Additionally, the HPE Aruba Networking CPSec Deployment Guide notes:
"CPSec secures the control plane by encrypting management traffic between APs and MCs, ensuring that attackers cannot eavesdrop on or tamper with this communication. It does not protect client data traffic, which is secured by wireless encryption protocols like WPA3." (Page 8, CPSec Benefits Section)

NEW QUESTION # 149
A company has Aruba Mobility Controllers (MCs). Aruba campus APs. and ArubaOS-CX switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type The ClearPass admins tell you that they want to run Network scans as part of the solution What should you do to configure the infrastructure to support the scans?

  • A. Create a TA profile on the ArubaOS-Switches with the root CA certificate for ClearPass's HTTPS certificate
  • B. Create device fingerprinting profiles on the ArubaOS-Switches that include SNMP. and apply the profiles to edge ports
  • C. Create remote mirrors on the ArubaOS-Swrtches that collect traffic on edge ports, and mirror it to CPPM's IP address.
  • D. Create SNMPv3 users on ArubaOS-CX switches, and make sure that the credentials match those configured on CPPM

Answer: D

Explanation:
To configure the infrastructure to support network scans as part of the ClearPass Policy Manager (CPPM) solution, creating SNMPv3 users on ArubaOS-CX switches is necessary. Ensuring that the credentials for these SNMPv3 users match those configured on CPPM is crucial for enabling CPPM to perform network scans effectively. SNMPv3 provides a secure method for network management by offering authentication and encryption, which are essential for safely conducting scans that classify endpoints by type. This configuration allows CPPM to communicate securely with the switches and gather necessary data without compromising network security.
References:
ArubaOS-CX configuration manuals that discuss SNMP settings.
Network management and security guidelines that emphasize the importance of secure SNMP configurations for network scanning and monitoring.


NEW QUESTION # 150
From which solution can ClearPass Policy Manager (CPPM) receive detailed information about client device type OS and status?

  • A. ClearPass OnGuard
  • B. ClearPass Guest
  • C. ClearPass Access Tracker
  • D. ClearPass Onboard

Answer: A

Explanation:
ClearPass Policy Manager (CPPM) can receive detailed information about client device type, OS, and status from ClearPass OnGuard. ClearPass OnGuard is part of the ClearPass suite and provides posture assessment and endpoint health checks. It gathers detailed information on the status and security posture of devices trying to connect to the network, such as whether antivirus software is up to date, which operating system is running, and other details that characterize the device's compliance with the network's security policies.
References:
Aruba ClearPass product documentation that details the capabilities of ClearPass OnGuard.
Network security resources that describe endpoint health checks and the importance of device posture assessment for access control.


NEW QUESTION # 151
How does the AOS firewall determine which rules to apply to a specific client's traffic?

  • A. The firewall applies the rules in policies associated with the client's WLAN.
  • B. The firewall applies every rule that includes the client's IP address as the source.
  • C. The firewall applies every rule that includes the client's IP address as the source or destination.
  • D. The firewall applies the rules in policies associated with the client's user role.

Answer: D

Explanation:
In an AOS-8 architecture, the Mobility Controller (MC) includes a stateful firewall that enforces policies on client traffic. The firewall uses user roles to apply policies, allowing granular control over traffic based on the client's identity and context.
User Roles: In AOS-8, each client is assigned a user role after authentication (e.g., via 802.1X, MAC authentication, or captive portal). The user role contains firewall policies (rules) that define what traffic is allowed or denied for clients in that role. For example, a "guest" role might allow only HTTP/HTTPS traffic, while an "employee" role might allow broader access.
Option A, "The firewall applies the rules in policies associated with the client's user role," is correct. The AOS firewall evaluates traffic based on the user role assigned to the client. Each role has a set of policies (rules) that are applied in order, and the first matching rule determines the action (permit or deny). For example, if a client is in the "employee" role, the firewall applies the rules defined in the "employee" role's policy.
Option B, "The firewall applies every rule that includes the client's IP address as the source," is incorrect. The firewall does not apply rules based solely on the client's IP address; it uses the user role. Rules within a role may include IP addresses, but the role determines which rules are evaluated.
Option C, "The firewall applies the rules in policies associated with the client's WLAN," is incorrect. While the WLAN configuration defines the initial role for clients (e.g., the default 802.1X role), the firewall applies rules based on the client's current user role, which may change after authentication (e.g., via a RADIUS VSA like Aruba-User-Role).
Option D, "The firewall applies every rule that includes the client's IP address as the source or destination," is incorrect for the same reason as Option B. The firewall uses the user role to determine which rules to apply, not just the client's IP address.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"The AOS firewall on the Mobility Controller applies rules based on the user role assigned to a client. Each user role contains a set of firewall policies that define the allowed or denied traffic for clients in that role. For example, a policy in the 'employee' role might include a rule like ipv4 user any http permit to allow HTTP traffic. The firewall evaluates the rules in the client's role in order, and the first matching rule determines the action for the traffic." (Page 325, Firewall Policies Section) Additionally, the HPE Aruba Networking Security Guide notes:
"User roles in AOS-8 provide a powerful mechanism for firewall policy enforcement. The firewall determines which rules to apply to a client's traffic by looking at the policies associated with the client's user role, which is assigned during authentication or via a RADIUS VSA like Aruba-User-Role."

NEW QUESTION # 152
What is a consideration for using MAC authentication (MAC-Auth) to secure a wired or wireless connection?

  • A. MAC-Auth can add a degree of security to an open WLAN by enabling the generation of a PMK to encrypt traffic.
  • B. It is very easy for hackers to spoof their MAC addresses and get around MAC authentication.
  • C. As a Layer 2 authentication method, MAC-Auth cannot be used to authenticate devices to an external authentication server.
  • D. Headless devices, such as Internet of Things (loT) devices, must be configured in advance to support MAC-Auth.

Answer: B

Explanation:
MAC authentication, also known as MAC-Auth, is a method used to authenticate devices based on their Media Access Control (MAC) address. It is often employed in both wired and wireless networks to grant network access based solely on the MAC address of a device. While MAC-Auth is straightforward and doesn't require complex configuration, it has significant security limitations primarily because MAC addresses can be easily spoofed. Attackers can change the MAC address of their device to match an authorized one, thereby gaining unauthorized access to the network. This susceptibility to MAC address spoofing makes MAC-Auth a weaker security mechanism compared to more robust authentication methods like 802.1X, which involves mutual authentication and encryption protocols.
