HP Aruba Certified Network Security Associate Exam Sample Questions (Q140-Q145):NEW QUESTION # 140
Your AOS 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?
  • A. The match method
  • B. The detecting devices
  • C. The match type
  • D. The confidence level
Answer: B
Explanation:
In an HPE Aruba Networking AOS-8 solution, the Wireless Intrusion Prevention (WIP) system is used to detect and classify rogue Access Points (APs). When a rogue AP is detected, the AOS system provides various pieces of information about the detected radio, such as the SSID, BSSID, match method, match type, confidence level, and the devices that detected the rogue AP. The goal is to locate the physical rogue device, which requires identifying its approximate location in the network environment.
Option A, "The detecting devices," is correct. The "detecting devices" refer to the authorized APs or radios that detected the rogue AP's signal. This information is critical for locating the rogue device because it provides the physical locations of the detecting APs. By knowing which APs detected the rogue AP and their signal strength (RSSI) readings, you can triangulate the approximate location of the rogue AP. For example, if AP-1 in Building A and AP-2 in Building B both detect the rogue AP, and AP-1 reports a stronger signal, the rogue AP is likely closer to AP-1 in Building A.
Option B, "The match method," is incorrect. The match method (e.g., "Plus one," "Eth-Wired-Mac-Table") indicates how the rogue AP was classified (e.g., based on a BSSID close to a known MAC or its presence on the wired network). While this helps understand why the AP was classified as rogue, it does not directly help locate the physical device.
Option C, "The confidence level," is incorrect. The confidence level indicates the likelihood that the AP is correctly classified as rogue (e.g., 90% confidence). This is useful for assessing the reliability of the classification but does not provide location information.
Option D, "The match type," is incorrect. The match type (e.g., "Rogue," "Suspected Rogue") specifies the category of the classification. Like the match method, it helps understand the classification but does not aid in physically locating the device.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"When a rogue AP is detected by the Wireless Intrusion Prevention (WIP) system, the 'detecting devices' information lists the authorized APs or radios that detected the rogue AP's signal. This is the most useful information for locating the rogue device, as it provides the physical locations of the detecting APs. By analyzing the signal strength (RSSI) reported by each detecting device, you can triangulate the approximate location of the rogue AP. For example, if AP-1 and AP-2 detect the rogue AP, and AP-1 reports a higher RSSI, the rogue AP is likely closer to AP-1." (Page 416, Rogue AP Detection Section) Additionally, the HPE Aruba Networking Security Guide notes:
"To locate a rogue AP, use the 'detecting devices' information in the AOS Detected Radios page. This lists the APs that detected the rogue AP, along with signal strength data, enabling triangulation to pinpoint the rogue device's location." (Page 80, Locating Rogue APs Section)

NEW QUESTION # 142
You have been instructed to look in an AOS 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?
  • A. MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue
  • B. MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue
  • C. MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering
  • D. MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor
Answer: B
Explanation:
The AOS Security Dashboard in an AOS-8 solution (Mobility Controllers or Mobility Master) provides a client list through its Wireless Intrusion Prevention (WIP) system, showing the classification of clients and the APs they are connected to. The goal is to identify clients that belong to the company (Authorized clients) and have connected to devices that might belong to hackers (rogue or suspected rogue APs).
Client Classification:
Authorized: A client that has successfully authenticated to an authorized AP and is 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.
Suspected Rogue: An AP that is not authorized and is suspected of being malicious, often because it exhibits suspicious behavior (e.g., a BSSID close to an authorized AP, indicating potential spoofing).
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).
Interfering: An AP that is not part of the company's network and may be causing interference, but is not necessarily malicious.
The requirement is to find a client that is Authorized (belongs to the company) and connected to a Suspected Rogue AP (might belong to hackers).
Option A: MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue This client is classified as "Authorized," meaning it belongs to the company, and it is connected to a "Suspected Rogue" AP, which might belong to hackers. This matches the requirement perfectly.
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: Interfering This client is "Interfering" (not a company client) and connected to an "Interfering" AP, which is not necessarily a hacker's device (it may just be causing interference).
Option D: MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue This client is "Interfering" (not a company client), although it is connected to a "Suspected Rogue" AP. It does not meet the requirement of being a company client.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"The Security Dashboard's client list in ArubaOS shows the classification of each client and the AP it is connected to. An 'Authorized' client is one that has successfully authenticated to an authorized AP and is part of the company's network. A 'Suspected Rogue' AP is an unauthorized AP that exhibits suspicious behavior, such as a BSSID close to an authorized AP, indicating potential spoofing by a hacker. To identify security risks, look for authorized clients connected to suspected rogue APs, as this may indicate a company device has connected to a malicious AP." (Page 415, Security Dashboard Section) Additionally, the HPE Aruba Networking Security Guide notes:
"WIP classifies clients as 'Authorized' if they have authenticated to an authorized AP managed by the controller. A 'Suspected Rogue' AP is a potential threat, as it may be attempting to mimic a legitimate AP to lure clients. Identifying authorized clients connected to suspected rogue APs is critical for detecting potential attacks, such as man-in-the-middle attempts by hackers." (Page 78, WIP Classifications Section)

NEW QUESTION # 143
What is one difference between EAP-Tunneled Layer Security (EAP-TLS) and Protected EAP (PEAP)?
  • A. EAP-TLS requires the supplicant to authenticate with a certificate, but PEAP allows the supplicant to use a username and password.
  • B. EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.
  • C. EAP-TLS creates a TLS tunnel for transmitting user credentials securely, while PEAP protects user credentials with TKIP encryption.
  • D. EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of its process.
Answer: A
Explanation:
EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) and PEAP (Protected EAP) are two EAP methods used for 802.1X authentication in wireless networks, such as those configured with WPA3-Enterprise on HPE Aruba Networking solutions. Both methods are commonly used with ClearPass Policy Manager (CPPM) for secure authentication.
EAP-TLS:
Requires both the supplicant (client) and the server (e.g., CPPM) to present a valid certificate during authentication.
Establishes a TLS tunnel to secure the authentication process, but the primary authentication mechanism is the mutual certificate exchange. The client's certificate is used to authenticate the client, and the server's certificate authenticates the server.
PEAP:
Requires only the server to present a certificate to authenticate itself to the client.
Establishes a TLS tunnel to secure the authentication process, within which the client authenticates using a secondary method, typically a username and password (e.g., via MS-CHAPv2 or EAP-GTC).
Option A, "EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of its process," is incorrect. Both EAP-TLS and PEAP establish a TLS tunnel. In EAP-TLS, the TLS tunnel is used for the mutual certificate exchange, while in PEAP, the TLS tunnel protects the inner authentication (e.g., username/password).
Option B, "EAP-TLS requires the supplicant to authenticate with a certificate, but PEAP allows the supplicant to use a username and password," is correct. This is a key difference: EAP-TLS mandates certificate-based authentication for the client, while PEAP allows the client to authenticate with a username and password inside the TLS tunnel, making PEAP more flexible for environments where client certificates are not deployed.
Option C, "EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake," is incorrect. Both methods use a TLS tunnel, and both authenticate the server during the TLS handshake (using the server's certificate). In EAP-TLS, the client's certificate is also part of the TLS handshake, while in PEAP, the client's credentials (username/password) are sent inside the tunnel after the handshake.
Option D, "EAP-TLS creates a TLS tunnel for transmitting user credentials securely, while PEAP protects user credentials with TKIP encryption," is incorrect. PEAP does not use TKIP (Temporal Key Integrity Protocol) for protecting credentials; TKIP is a legacy encryption method used in WPA/WPA2 for wireless data encryption, not for EAP authentication. PEAP uses the TLS tunnel to protect the inner authentication credentials.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"EAP-TLS requires both the supplicant and the server to present a valid certificate for mutual authentication. The supplicant authenticates using its certificate, and the process is secured within a TLS tunnel. In contrast, PEAP requires only the server to present a certificate to establish a TLS tunnel, within which the supplicant can authenticate using a username and password (e.g., via MS-CHAPv2 or EAP-GTC). This makes PEAP more suitable for environments where client certificates are not deployed." (Page 292, EAP Methods Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"A key difference between EAP-TLS and PEAP is the client authentication method. EAP-TLS mandates that the client authenticate with a certificate, requiring certificate deployment on all clients. PEAP allows the client to authenticate with a username and password inside a TLS tunnel, making it easier to deploy in environments without client certificates."

NEW QUESTION # 144
You configure an ArubaOS-Switch to enforce 802.1X authentication with ClearPass Policy Manager (CPPM) denned as the RADIUS server Clients cannot authenticate You check Aruba ClearPass Access Tracker and cannot find a record of the authentication attempt.
What are two possible problems that have this symptom? (Select two)
  • A. Clients are not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate.
  • B. CPPM does not have a network device defined for the switch's IP address.
  • C. Clients are configured to use a mismatched EAP method from the one In the CPPM service.
  • D. The RADIUS shared secret does not match between the switch and CPPM.
  • E. users are logging in with the wrong usernames and passwords or invalid certificates.
Answer: B,D
Explanation:
If clients cannot authenticate and there is no record of the authentication attempt in Aruba ClearPass Access Tracker, two possible problems that could cause this symptom are:
The RADIUS shared secret does not match between the switch and CPPM. This mismatch would prevent the switch and CPPM from successfully communicating, so authentication attempts would fail, and no record would appear in Access Tracker.
CPPM does not have a network device profile defined for the switch's IP address. Without a network device profile, CPPM would not recognize authentication attempts coming from the switch and would not process them, resulting in no logs in Access Tracker.
The other options are incorrect because:
Users logging in with the wrong credentials would still generate an attempt record in Access Tracker.
Clients configured to use a mismatched EAP method would also generate an attempt record in Access Tracker.
Clients not configured to trust the root CA certificate for CPPM's RADIUS/EAP certificate might fail authentication, but the attempt would still be logged in Access Tracker.
