Your ArubaoS solution has detected a rogue AP with Wireless intrusion Prevention (WIP).
Which information about the detected radio can best help you to locate the rogue device?

  1. the match method
  2. the detecting devices
  3. the match type
  4. the confidence level

Answer(s): B

Explanation:

When an ArubaOS solution detects a rogue AP with Wireless Intrusion Prevention (WIP), the most crucial information that can help locate the rogue device is the detecting devices. This is because the detecting devices can provide the physical location or the network topology context where the rogue AP has been detected1.
The detecting devices are typically the Air Monitors (AMs) or Access Points (APs) in the network that have identified the rogue AP's presence. These devices can provide information such as the signal strength and the direction from which the rogue AP's signals are being received. By triangulating this information from multiple detecting devices, it becomes possible to pinpoint the physical location of the rogue AP2.
Additionally, the detecting devices can log events and alerts that can be reviewed to understand the rogue AP's behavior, such as the channels it is operating on and the potential impact on the authorized wireless network1. This information is vital for network administrators to quickly and effectively respond to the threat posed by the rogue AP. In contrast, the match method (A) and match type © relate to how the rogue AP is classified and identified by the system, which is useful for classification but not for physical location. The confidence level (D) indicates the system's certainty in the classification but does not aid in locating the device2.



What is a benefit of deploying Aruba ClearPass Device insight?

  1. Highly accurate endpoint classification for environments with many devices types, including Internet of Things (loT)
  2. visibility into devices' 802.1X supplicant settings and automated certificate deployment
  3. Agent-based analysts of devices' security settings and health status, with the ability to implement quarantining
  4. Simpler troubleshooting of ClearPass solutions across an environment with multiple ClearPass Policy Managers

Answer(s): A

Explanation:

Aruba ClearPass Device Insight offers a significant benefit by providing highly accurate endpoint classification. This feature is particularly useful in complex environments with a wide variety of device types, including IoT devices. Accurate device classification allows network administrators to better understand the nature and behavior of devices on their network, which is crucial for implementing appropriate security policies and ensuring network performance and security.


Reference:

This feature is highlighted in Aruba ClearPass Device Insight literature and is a major selling point of the product as it addresses the challenges posed by diverse and growing device environments in modern networks.



What is a benefit or using network aliases in ArubaOS firewall policies?

  1. You can associate a reputation score with the network alias to create rules that filler traffic based on reputation rather than IP.
  2. You can use the aliases to translate client IP addresses to other IP addresses on the other side of the firewall
  3. You can adjust the IP addresses in the aliases, and the rules using those aliases automatically update
  4. You can use the aliases to conceal the true IP addresses of servers from potentially untrusted clients.

Answer(s): C

Explanation:

In ArubaOS firewall policies, using network aliases allows administrators to manage groups of IP addresses more efficiently. By associating multiple IPs with a single alias, any changes made to the alias (like adding or removing IP addresses) are automatically reflected in all firewall rules that reference that alias. This significantly simplifies the management of complex rulesets and ensures consistency across security policies, reducing administrative overhead and minimizing the risk of errors.


Reference:

This functionality is part of the ArubaOS firewall management features, designed to enhance the usability and flexibility of network security configurations in dynamic network environments.



What is a guideline for managing local certificates on an ArubaOS-Switch?

  1. Before installing the local certificate, create a trust anchor (TA) profile with the root CA certificate for the certificate that you will install
  2. Install an Online Certificate Status Protocol (OCSP) certificate to simplify the process of enrolling and re-enrolling for certificate
  3. Generate the certificate signing request (CSR) with a program offline, then, install both the certificate and the private key on the switch in a single file.
  4. Create a self-signed certificate online on the switch because ArubaOS-Switches do not support CA- signed certificates.

Answer(s): A

Explanation:

When managing local certificates on an ArubaOS-Switch, a recommended guideline is to create a trust anchor (TA) profile with the root CA certificate before installing the local certificate. This step ensures that the switch can verify the authenticity of the certificate chain during SSL/TLS communications. The trust anchor profile establishes a basis of trust by containing the root CA

certificate, which helps validate the authenticity of any subordinate certificates, including the local certificate installed on the switch. This process is essential for enhancing security on the network, as it ensures that encrypted communications involving the switch are based on a verified certificate hierarchy.

What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?

  1. A DDoS attack originates from external devices, while a DoS attack originates from internal devices
  2. A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device
  3. A DoS attack targets one server, a DDoS attack targets all the clients that use a server
  4. A DDoS attack targets multiple devices, while a DoS Is designed to Incapacitate only one device

Answer(s): B

Explanation:

The main distinction between a Distributed Denial of Service (DDoS) attack and a traditional Denial of Service (DoS) attack is that a DDoS attack is launched from multiple devices, whereas a DoS attack originates from a single device. This distinction is critical because the distributed nature of a DDoS attack makes it more difficult to mitigate. Multiple attacking sources can generate a higher volume of malicious traffic, overwhelming the target more effectively than a single source, as seen in a DoS attack. DDoS attacks exploit a variety of devices across the internet, often coordinated using botnets, to flood targets with excessive requests, leading to service degradation or complete service denial.
