You have been instructed to look in the ArubaOS Security Dashboard's client list. Your goal is to find clients that belong to the company and have connected to devices that might belong to hackers. Which client fits this description?
Correct Answer: D
The ArubaOS Security Dashboard, part of the AOS-8 architecture (Mobility Controllers or Mobility Master), provides visibility into wireless clients and access points (APs) through its Wireless Intrusion Prevention (WIP) system. The goal is to identify clients that belong to the company (i.e., authorized clients) and have connected to devices that might belong to hackers (i.e., rogue APs). Client Classification: Authorized: A client that has successfully authenticated to an authorized AP and is recognized as part of the company's network (e.g., an employee device). Interfering: A client that is not authenticated to the company's network and is considered external or potentially malicious. AP Classification: Authorized: An AP that is part of the company's network and managed by the MC/MM. Rogue: An AP that is not authorized and is suspected of being malicious (e.g., connected to the company's wired network without permission). Neighbor: An AP that is not part of the company's network but is not connected to the wired network (e.g., a nearby AP from another organization). The requirement is to find a client that is authorized (belongs to the company) and connected to a rogue AP (might belong to hackers). Option A: MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Rogue This client is classified as "Interfering," meaning it does not belong to the company. Although it is connected to a rogue AP, it does not meet the requirement of being a company client. Option B: MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor This client is "Interfering" (not a company client) and connected to a "Neighbor" AP, which is not considered a hacker's device (it's just a nearby AP). Option C: MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Authorized This client is "Interfering" (not a company client) and connected to an "Authorized" AP, which is part of the company's network, not a hacker's device. Option D: MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Rogue This client is "Authorized," meaning it belongs to the company, and it is connected to a "Rogue" AP, which might belong to hackers. This matches the requirement perfectly. The HPE Aruba Networking AOS-8 8.11 User Guide states: "The Security Dashboard in ArubaOS provides a client list that includes the client classification and the AP classification for each client. A client classified as 'Authorized' has successfully authenticated to an authorized AP and is part of the company's network. A 'Rogue' AP is an unauthorized AP that is suspected of being malicious, often because it is connected to the company's wired network (e.g., detected via Eth-Wired-Mac-Table match). To identify potential security risks, look for authorized clients connected to rogue APs, as this may indicate that a company device has connected to a hacker's AP." (Page 415, Security Dashboard Section) Additionally, the HPE Aruba Networking Security Guide notes: "An 'Authorized' client is one that has authenticated to an AP managed by the controller, typically an employee or corporate device. A 'Rogue' AP is classified as such if it is not authorized and poses a potential threat, such as being connected to the corporate LAN. Identifying authorized clients connected to rogue APs is critical for detecting potential man-in-the-middle attacks."

Question 2
Which attack is an example or social engineering?
Correct Answer: A
An example of a social engineering attack is described in option A, where an email is used to impersonate a bank and deceive users into entering their bank login information on a counterfeit website. Social engineering attacks exploit human psychology rather than technical hacking techniques to gain access to systems, data, or personal information. These attacks often involve tricking people into breaking normal security procedures. The other options describe different types of technical attacks that do not primarily rely on manipulating individuals through deceptive personal interactions.
Question 3
You are deploying a new wireless solution with an Aruba Mobility Master (MM). Aruba Mobility Controllers (MCs), and campus APs (CAPs). The solution will include a WLAN that uses Tunnel for the forwarding mode and WPA3-Enterprise for the security option. You have decided to assign the WLAN to VLAN 301, a new VLAN. A pair of core routing switches will act as the default router for wireless user traffic. Which links need to carry VLAN 301?
Correct Answer: B
In a wireless network deployment with Aruba Mobility Master (MM), Mobility Controllers (MCs), and Campus APs (CAPs), where a WLAN is configured to use Tunnel mode for forwarding, the user traffic is tunneled from the APs to the MCs. VLAN 301, which is assigned to the WLAN, must be present on the links from the MCs to the core routing switches because these switches act as the default router for the wireless user traffic. It is not necessary for the VLAN to be present on all campus LAN links or AP links, only between the MCs and the core routing switches where the routing for VLAN 301 will occur.
Question 4
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?
Correct Answer: B
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. : Cybersecurity texts and resources that differentiate between types of denial of service attacks. Technical documentation and analysis of DDoS tactics, which illustrate how botnets and other distributed systems are employed to execute attacks.
Question 5
A company is deploying ArubaOS-CX switches to support 135 employees, which will tunnel client traffic to an Aruba Mobility Controller (MC) for the MC to apply firewall policies and deep packet inspection (DPI). This MC will be dedicated to receiving traffic from the ArubaOS-CX switches. What are the licensing requirements for the MC?
Correct Answer: B
When deploying ArubaOS-CX switches that tunnel client traffic to an Aruba Mobility Controller (MC), the licensing requirements typically involve Policy Enforcement Firewall (PEF) licenses. These licenses enable the MC to enforce firewall policies and perform deep packet inspection (DPI). Therefore, for each switch tunneling traffic to the MC, a PEF license would be necessary.
