HP Aruba Certified Network Security Associate Exam Sample Questions (Q135-Q140):

NEW QUESTION # 135
What is one difference between EAP-Tunneled Layer Security (EAP-TLS) and Protected EAP (PEAP)?

  • A. EAP-TLS creates a TLS tunnel for transmitting user credentials securely, while PEAP protects user credentials with TKIP encryption.
  • B. EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of its process.
  • C. EAP-TLS requires the supplicant to authenticate with a certificate, but PEAP allows the supplicant to use a username and password.
  • D. EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.

Answer: C

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 # 136
The first exhibit shows roles on the MC, listed in alphabetic order. The second and third exhibits show the configuration for a WLAN to which a client connects. Which description of the role assigned to a user under various circumstances is correct?

  • A. A user fails 802.1X authentication. The client remains connected, but is assigned the "guest" role.
  • B. A user authenticates successfully with 802.1X, and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employeel." The client's role is "employeel."
  • C. A user authenticates successfully with 802.1X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employee." The client's role is "guest."
  • D. A user authenticates successfully with 802.1 X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employeel." The client's role is "guest."

Answer: B

Explanation:
In a WLAN setup that uses 802.1X for authentication, the role assigned to a user is determined by the result of the authentication process. When a user successfully authenticates via 802.1X, the RADIUS server may include a Vendor-Specific Attribute (VSA), such as the Aruba-User-Role, in the Access-Accept message. This attribute specifies the role that should be assigned to the user. If the RADIUS Access-Accept message includes an Aruba-User-Role VSA set to "employee1", the client should be assigned the "employee1" role, as per the VSA, and not the default "guest" role. The "guest" role would typically be a fallback if no other role is specified or if the authentication fails.


NEW QUESTION # 137
What is a vulnerability of an unauthenticated Dime-Heliman exchange?

  • A. A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values
  • B. Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.
  • C. Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.
  • D. A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.

Answer: D


NEW QUESTION # 138
What role does the Aruba ClearPass Device Insight Analyzer play in the Device Insight architecture?

  • A. It resides In the cloud and applies machine learning and supervised crowdsourcing to metadata sent by Collectors
  • B. It resides in the cloud and manages licensing and configuration for Collectors
  • C. It resides on-prem and is responsible for running active SNMP and Nmap scans
  • D. It resides on-prem and provides the span port to which traffic is mirrored for deep analytics.

Answer: A

Explanation:
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.
