Correct Answer: B
Question 7
Your HPE Aruba Networking Mobility Master-based solution has detected a rogue AP. Among other information, the AOS Detected Radios page lists this information for the AP: SSID = PublicWiFi BSSID = a8:bd:27:12:34:56 Match method = Plus one Match method = Eth-Wired-Mac-Table The security team asks you to explain why this AP is classified as a rogue. What should you explain?
Correct Answer: B
HPE Aruba Networking's Wireless Intrusion Prevention (WIP) system, part of the AOS-8 architecture (Mobility Master and Mobility Controllers), is designed to detect and classify rogue APs. The "AOS Detected Radios" page provides details about detected APs, including their SSID, BSSID, and match methods used to classify them. In this case, the AP is classified as a rogue with the following match methods: Plus one: This indicates that the BSSID of the detected AP is numerically close (e.g., differs by one in the last octet) to the MAC address of a known device in the network. Eth-Wired-Mac-Table: This indicates that the AP's MAC address (or a closely related MAC address) was found in the wired network's MAC address table, suggesting that the AP is connected to the LAN. These match methods suggest that the AP is likely connected to the company's wired LAN (via the Eth-Wired-Mac-Table match) and has a BSSID that is close to a known device's MAC address (Plus one match). Since this AP is not part of the company's authorized AP list (it's broadcasting "PublicWiFi," which may not be a corporate SSID), it is classified as a suspected rogue. This scenario is common when an unauthorized AP is plugged into the corporate LAN, posing a security risk. Option A, "The AP has been detected using multiple MAC addresses," is incorrect because the match methods do not indicate multiple MAC addresses; they indicate a close match to a known MAC and a presence in the wired MAC table. Option C, "The AP is an AP that belongs to your solution," is incorrect because the AP is classified as a rogue, meaning it is not part of the authorized APs in the solution. Option D, "The AP has a BSSID that is close to your authorized APs' BSSIDs," is partially correct in that the "Plus one" match indicates a close BSSID, but the key reason for the rogue classification is its connection to the LAN (Eth-Wired-Mac-Table), not just the BSSID similarity. The HPE Aruba Networking AOS-8 8.11 User Guide states: "The Wireless Intrusion Prevention (WIP) system detects rogue APs by analyzing their BSSIDs, SSIDs, and connectivity to the wired network. The 'Eth-Wired-Mac-Table' match method indicates that the AP's MAC address (or a closely related address) was found in the wired network's MAC address table, suggesting that the AP is connected to the LAN. The 'Plus one' match method indicates that the AP's BSSID is numerically close to a known MAC address in the network, which can indicate a potential rogue device attempting to mimic a legitimate device." (Page 412, Rogue AP Detection Section) Additionally, the guide notes: "A rogue AP is classified as 'suspected rogue' if it is detected on the wired network (e.g., via Eth-Wired-Mac-Table) and is not part of the authorized AP list. This often occurs when an unauthorized AP is connected to the corporate LAN."

Question 8
What is a reason to set up a packet capture on an Aruba Mobility Controller (MC)?
Correct Answer: B
Setting up a packet capture on an Aruba Mobility Controller (MC) is particularly useful in scenarios where detailed analysis of network traffic is necessary to identify and address security concerns. Option B is the correct answer because it directly addresses the need to closely examine the traffic of a potentially malicious wireless endpoint. Packet capture on the MC allows the security team to collect and analyze traffic to/from specific endpoints in real-time, providing valuable insights into the nature of the traffic and potentially identifying harmful activities. This capability is essential for forensics and troubleshooting security incidents, enabling administrators to respond effectively to threats. : Aruba Mobility Controller Configuration Guide Aruba Networks Official Documentation
Question 9
What role does the Aruba ClearPass Device Insight Analyzer play in the Device Insight architecture?
Correct Answer: D
The Aruba ClearPass Device Insight Analyzer plays a crucial role within the Device Insight architecture by residing in the cloud and applying machine learning and supervised crowdsourcing to the metadata sent by Collectors. This component of the architecture is responsible for analyzing vast amounts of data collected from the network to identify and classify devices accurately. By utilizing machine learning algorithms and crowdsourced input, the Device Insight Analyzer enhances the accuracy of device detection and classification, thereby improving the overall security and management of the network. References: Aruba ClearPass official documentation and whitepapers that detail the functionality and deployment of the Device Insight Analyzer. Technical articles and presentations on network security solutions that discuss the use of machine learning and data analytics in device management.
Question 10
What is a Key feature of me ArubaOS firewall?
Correct Answer: A
The ArubaOS firewall is a stateful firewall, meaning that it can track the state of active sessions and can make decisions based on the context of the traffic. This stateful inspection capability allows it to automatically allow return traffic for sessions that it has permitted, thereby enabling seamless two-way communication for authorized users while maintaining the security posture of the network. : ArubaOS firewall documentation.
