HP HPE6-A78 Actual Questions

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.

The ArubaOS firewall determines which rules to apply to a specific client's traffic based on the rules in policies associated with the client's user role. User roles are a fundamental part of ArubaOS and the firewall policies they encompass. These roles contain policies that dictate permissions and restrictions for network traffic. When a client authenticates, it is assigned a role, and the firewall enforces the rules defined within that role for the client's traffic.

In SNMPv3, security is paramount and each SNMP entity (client or agent) needs to have a user with a security name (username) and optionally, a security level which determines whether authentication and encryption are used. When configuring SNMPv3 users on network infrastructure devices, it is essential to match the username, authentication (auth) algorithm, authentication key (auth key), privacy (priv) algorithm, and privacy key (priv key) exactly as they are configured on the SNMP server to ensure successful communication.

This is because the SNMPv3 security model relies on a combination of a username and a pair of keys (authentication and privacy keys) to uniquely identify and secure communication between the agent and the manager. The keys are used to verify the integrity (auth key) and confidentiality (priv key) of the messages. Using the same algorithms ensures that the messages can be properly encrypted and decrypted on both ends.

Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.
