HP Aruba Certified Network Security Professional Exam Sample Questions (Q43-Q48):

NEW QUESTION # 43
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. Enabling debugging of security functions on the switches.
  • D. Configure the switches to implement RADIUS accounting to HPE Aruba Networking ClearPass and enable HPE Aruba Networking ClearPass Insight.

Answer: A

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 # 44
What is one benefit of integrating HPE Aruba Networking ClearPass Policy Manager (CPPM) with third-party solutions such as Mobility Device Management (MDM) and firewalls?

  • A. CPPM can exchange contextual information about clients with third-party solutions, which helps make better decisions.
  • B. CPPM can take over filtering internal traffic so that the third-party solutions have more processing power to devote to filtering external traffic.
  • C. CPPM can offload policy decisions to the third-party solutions, enabling CPPM to respond to authentication requests more quickly.
  • D. CPPM can make the third-party solutions more secure by adding signature-based threat detection capabilities.

Answer: A

Explanation:
* Contextual Exchange for Better Decisions:
* HPE Aruba ClearPass can integrate with third-party solutions like MDM and firewalls to exchange contextual information about endpoints (e.g., device type, posture, location).
* This integration allows ClearPass and the third-party solutions to make better access control and security decisions.
* For example:
* An MDM can inform CPPM about device compliance, and CPPM can adjust enforcement policies dynamically.
* Firewalls can receive updated context about users and devices to enforce policies more effectively.
* Option Analysis:
* Option A: Correct. Exchanging contextual information improves access control decisions.
* Option B: Incorrect. CPPM does not provide signature-based threat detection.
* Option C: Incorrect. CPPM does not offload policy decisions; it integrates for collaboration.
* Option D: Incorrect. CPPM does not replace third-party traffic filtering capabilities.


NEW QUESTION # 45
A company wants HPE Aruba Networking ClearPass Policy Manager (CPPM) to respond to Syslog messages from its Palo Alto Next Generation Firewall (NGFW) by quarantining clients involved in security incidents.
Which step must you complete to enable CPPM to process the Syslogs properly?

  • A. Configure CPPM to trust the root CA certificate for the NGFW.
  • B. Configure the Palo Alto as a context server on CPPM.
  • C. Enable Insight and ingress event processing on the CPPM server.
  • D. Install a Palo Alto Extension through ClearPass Guest.

Answer: B

Explanation:
To enable HPE Aruba Networking ClearPass Policy Manager (CPPM) to process Syslog messages from a Palo Alto Next Generation Firewall (NGFW) and quarantine clients involved in security incidents, you need to configure the Palo Alto as a context server on CPPM. This setup allows CPPM to receive and understand the context of the Syslog messages sent by the Palo Alto NGFW, enabling it to take appropriate actions such as quarantining clients.
1.Context Server Configuration: Configuring the Palo Alto NGFW as a context server in CPPM ensures that CPPM can process and respond to Syslog messages effectively.
2.Security Incident Response: By understanding the context of the Syslog messages, CPPM can automatically trigger actions like client quarantine based on security incidents detected by the NGFW.
3.Integration: This integration enhances the overall security posture by enabling coordinated responses between the firewall and CPPM.


NEW QUESTION # 46
Refer to the Exhibit:

These packets have been captured from VLAN 10. which supports clients that receive their IP addresses with DHCP.
What can you interpret from the packets that you see here?
These packets have been captured from VLAN 10, which supports clients that receive their IP addresses with DHCP. What can you interpret from the packets that you see here?

  • A. Someone is possibly implementing an ARP poisoning and MITM attack.
  • B. Someone is possibly implementing a MAC spoofing attack to gain unauthorized access.
  • C. The mirroring session that captured the packets was likely misconfigured and captured duplicate traffic.
  • D. An admin has likely misconfigured two clients to use the same DHCP settings.

Answer: B

Explanation:
The exhibit reveals duplicate IP addresses detected for 10.1.140.6, associated with two different MAC addresses:
* 88:56:56:ab:c6:89
* 88:13:30:a3:02:00
Key observations:
* Duplicate IP Address Detection:
* The message "Duplicate IP address detected for 10.1.140.6" clearly indicates two devices claiming the same IP address.
* This typically occurs when one device spoofs the MAC address of another device to intercept or disrupt traffic.
* MAC Spoofing Context:
* MAC spoofing is a tactic used to impersonate another device's hardware address to gain unauthorized access to a network.
* By spoofing a legitimate IP-MAC pairing, an attacker can bypass security mechanisms or cause denial-of-service conditions.
* Why the Other Options are Incorrect:
* Option B (Mirroring Misconfigured): While mirroring misconfiguration can duplicate traffic, it does not lead to a "duplicate IP detected" alert.
* Option C (Misconfigured DHCP): Misconfigurations usually result in DHCP conflicts, but they do not typically involve two different MAC addresses for the same IP.
* Option D (ARP Poisoning/MITM): ARP poisoning involves falsified ARP tables, but it does not directly trigger duplicate IP address detection. Instead, ARP packets flood the network.
Conclusion:
The evidence strongly suggests MAC spoofing, as two different MAC addresses are claiming the same IP address (10.1.140.6). This behavior is typical of attempts to gain unauthorized access or disrupt network operations.


NEW QUESTION # 47
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. The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.
  • C. You can install multiple scripts on a switch, but you can deploy only one agent per script.
  • D. When you use custom scripts, you can create as many agents from each script as you want.

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.
