HP Aruba Certified Network Security Associate Exam Sample Questions (Q127-Q132):NEW QUESTION # 127
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?
  • A. Rather than function wirelessly, tarpit containment sends ARP frames over the wired network to poison rogue APs ARP tables and prevent them from transmitting on the wired network.
  • B. Rather than target all clients connected to rogue APs, tarpit containment targets only authorized clients that are connected to a rogue AP, reducing the chance of negative effects on neighbors.
  • C. Tarpit containment forms associations with clients to enable more effective containment with fewer disassociation frames than traditional wireless containment.
  • D. Tarpit containment does not require an RF Protect license to function, while traditional wireless containment does.
Answer: C
Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs. It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.

NEW QUESTION # 128
A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-Switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other ClearPass solutions.
The ClearPass admins tell you that they want to use HTTP User-Agent strings to help classify endpoints.
What should you do as a part of configuring the ArubaOS-Switches to support this requirement?
  • A. Connect the switches to CPPM's span ports, and set up mirroring of HTTP traffic on the switches.
  • B. Create a device fingerprinting policy that includes HTTP, and apply the policy to edge ports.
  • C. Configure CPPM as the sFlow collector, and make sure that sFlow is enabled on edge ports.
  • D. Create remote mirrors that collect traffic on edge ports, and mirror it to CPPM's IP address.
Answer: C
Explanation:
ArubaOS-Switches can use sFlow technology to sample network traffic and send the samples to a collector, such as ClearPass Policy Manager (CPPM), for analysis. sFlow can be configured to capture various types of traffic, including HTTP, which typically contains User-Agent strings that can be used for device fingerprinting and classification.
To support the requirement for using HTTP User-Agent strings to classify endpoints, the switches would need to be configured to send sFlow samples containing HTTP traffic to CPPM. CPPM would then analyze these samples and use the User-Agent strings to classify the devices.
Therefore, the correct action to configure ArubaOS-Switches would involve:
Configuring CPPM as the sFlow collector on the switches.
Enabling sFlow on the edge ports that connect to endpoints.
This approach allows the network traffic to be analyzed by CPPM without requiring any additional mirroring or redirection of traffic, which would be resource-intensive and potentially disruptive to network performance.

NEW QUESTION # 129
Refer to the exhibit.

What Is a part of the setup on the MC?
  • A. Configure a ClearPass username and password in the MyEmployees AAA profile.
  • B. Create a dynamic authorization, or RFC 3576, server with the 10.5.5.5 address and correct shared secret.
  • C. Install the root CA associated with the 10 5.5.5 server's certificate as a Trusted CA certificate.
  • D. Enable the dynamic authorization setting in the "clearpass" authentication server settings.
Answer: C

NEW QUESTION # 130
What is one way a honeypot can be used to launch a man-in-the-middle (MITM) attack to wireless clients?
  • A. It uses ARP poisoning to disconnect wireless clients from the legitimate wireless network and force clients to connect to the hacker's wireless network instead.
  • B. It uses a combination of software and hardware to jam the RF band and prevent the client from connecting to any wireless networks.
  • C. It runs an NMap scan on the wireless client to find the client's MAC and IP address. The hacker then connects to another network and spoofs those addresses.
  • D. It examines wireless clients' probes and broadcasts the SSIDs in the probes, so that wireless clients will connect to it automatically.
Answer: D
Explanation:
A honeypot in the context of wireless networks is a rogue access point (AP) set up by an attacker to lure wireless clients into connecting to it, often to steal credentials, intercept traffic, or launch further attacks. A man-in-the-middle (MITM) attack involves the attacker positioning themselves between the client and the legitimate network to intercept or manipulate traffic.
Option D, "It examines wireless clients' probes and broadcasts the SSIDs in the probes, so that wireless clients will connect to it automatically," is correct. Wireless clients periodically send probe requests to discover available networks, including SSIDs they have previously connected to (stored in their Preferred Network List, PNL). A honeypot AP can capture these probe requests, identify the SSIDs the client is looking for, and then broadcast those SSIDs. If the honeypot AP has a stronger signal or the legitimate AP is not available, the client may automatically connect to the honeypot AP (especially if the SSID is in the PNL and auto-connect is enabled). Once connected, the attacker can intercept the client's traffic, making this an effective MITM attack.
Option A, "It uses ARP poisoning to disconnect wireless clients from the legitimate wireless network and force clients to connect to the hacker's wireless network instead," is incorrect. ARP poisoning is a technique used on wired networks (or within the same broadcast domain) to redirect traffic by spoofing ARP responses. In a wireless context, ARP poisoning is not typically used to disconnect clients from a legitimate AP. Instead, techniques like deauthentication attacks or SSID spoofing (as in Option D) are more common.
Option B, "It runs an NMap scan on the wireless client to find the client's MAC and IP address. The hacker then connects to another network and spoofs those addresses," is incorrect. NMap scans are used for network discovery and port scanning, not for launching an MITM attack via a honeypot. Spoofing MAC and IP addresses on another network does not position the attacker as a honeypot to intercept wireless traffic.
Option C, "It uses a combination of software and hardware to jam the RF band and prevent the client from connecting to any wireless networks," is incorrect. Jamming the RF band would disrupt all wireless communication, including the attacker's honeypot, and would not facilitate an MITM attack. Jamming might be used in a denial-of-service (DoS) attack, but not for MITM.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"A common technique for launching a man-in-the-middle (MITM) attack using a honeypot AP involves capturing wireless clients' probe requests to identify SSIDs in their Preferred Network List (PNL). The honeypot AP then broadcasts these SSIDs, tricking clients into connecting automatically if the SSID matches a known network and auto-connect is enabled. Once connected, the attacker can intercept the client's traffic, performing an MITM attack." (Page 422, Wireless Threats Section) Additionally, the HPE Aruba Networking Security Guide notes:
"Honeypot APs can be used to launch MITM attacks by spoofing SSIDs that clients are probing for. Clients often automatically connect to known SSIDs in their PNL, especially if the legitimate AP is unavailable or the honeypot AP has a stronger signal, allowing the attacker to intercept traffic."

NEW QUESTION # 131
A company has HPE Aruba Networking Mobility Controllers (MCs), campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other HPE Aruba Networking ClearPass solutions.
The HPE Aruba Networking ClearPass admins tell you that they want to use HTTP User-Agent strings to help profile the endpoints.
What should you do as a part of setting up Mobility Controllers (MCs) to support this requirement?
  • A. Create control path mirrors to mirror HTTP traffic from clients to CPPM.
  • B. Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM.
  • C. Create a firewall whitelist rule that permits HTTP and CPPM's IP address.
  • D. Create datapath mirrors that use the CPPM's IP address as the destination.
Answer: D
Explanation:
HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to classify endpoints, and one of its profiling methods involves analyzing HTTP User-Agent strings to identify device types (e.g., iPhone, Windows laptop). HTTP User-Agent strings are sent in HTTP headers when a client accesses a website. For CPPM to profile devices using HTTP User-Agent strings, it must receive the HTTP traffic from the clients. In this scenario, the company is using Mobility Controllers (MCs), campus APs, and AOS-CX switches, and CPPM is the only ClearPass solution in use.
HTTP User-Agent Profiling: CPPM can passively profile devices by analyzing HTTP traffic, but it needs to receive this traffic. In an AOS-8 architecture, the MC can mirror client traffic to CPPM for profiling. Since HTTP traffic is part of the data plane (user traffic), the MC must mirror the data plane traffic (not control plane traffic) to CPPM.
Option A, "Create datapath mirrors that use the CPPM's IP address as the destination," is correct. The MC can be configured to mirror client HTTP traffic to CPPM using a datapath mirror (also known as a GRE mirror). This involves setting up a mirror session on the MC that sends a copy of the client's HTTP traffic to CPPM's IP address. CPPM then analyzes the HTTP User-Agent strings in this traffic to profile the endpoints. For example, the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http can be used to mirror HTTP traffic to CPPM.
Option B, "Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM," is incorrect. IF-MAP (Interface for Metadata Access Points) is a protocol used for sharing profiling data between ClearPass and other systems (e.g., Aruba Introspect), but it is not used for sending HTTP traffic to CPPM for profiling. Additionally, IF-MAP is not relevant when only CPPM is in use.
Option C, "Create control path mirrors to mirror HTTP traffic from clients to CPPM," is incorrect. Control path (control plane) traffic includes management traffic between the MC and APs (e.g., AP registration, heartbeats), not client HTTP traffic. HTTP traffic is part of the data plane, so a datapath mirror is required, not a control path mirror.
Option D, "Create a firewall whitelist rule that permits HTTP and CPPM's IP address," is incorrect. A firewall whitelist rule on the MC might be needed to allow traffic to CPPM, but this is not the primary step for enabling HTTP User-Agent profiling. The key requirement is to mirror the HTTP traffic to CPPM, which is done via a datapath mirror, not a firewall rule.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"To enable ClearPass Policy Manager (CPPM) to profile devices using HTTP User-Agent strings, the Mobility Controller (MC) must mirror client HTTP traffic to CPPM. This is done by creating a datapath mirror session that sends a copy of the client's HTTP traffic to CPPM's IP address. For example, use the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http to mirror HTTP traffic to CPPM. CPPM then analyzes the HTTP User-Agent strings to classify endpoints by type (e.g., iPhone, Windows laptop)." (Page 350, Device Profiling with CPPM Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
"HTTP User-Agent profiling requires ClearPass to receive HTTP traffic from clients. In an Aruba Mobility Controller environment, configure a datapath mirror to send HTTP traffic to ClearPass's IP address. ClearPass will parse the HTTP User-Agent strings to identify device types and operating systems, enabling accurate profiling." (Page 249, HTTP User-Agent Profiling Section)
