HP Aruba Certified Network Security Associate Exam Sample Questions (Q59-Q64):NEW QUESTION # 59
An admin has created a WLAN that uses the settings shown in the exhibits (and has not otherwise adjusted the settings in the AAA profile) A client connects to the WLAN Under which circumstances will a client receive the default role assignment?
A. The client has passed 802 1X authentication and the authentication server did not send an Aruba-User-Role VSA
B. The client has attempted 802 1X authentication, but failed to maintain a reliable connection, leading to a timeout error
C. The client has attempted 802 1X authentication, but the MC could not contact the authentication server
D. The client has passed 802 1X authentication, and the value in the Aruba-User-Role VSA matches a role on the MC
Answer: A
Explanation:
In the context of an Aruba Mobility Controller (MC) configuration, a client will receive the default role assignment if they have passed 802.1X authentication and the authentication server did not send an Aruba-User-Role Vendor Specific Attribute (VSA). The default role is assigned by the MC when a client successfully authenticates but the authentication server provides no specific role instruction. This behavior ensures that a client is not left without any role assignment, which could potentially lead to a lack of network access or access control. This default role assignment mechanism is part of Aruba's role-based access control, as documented in the ArubaOS user guide and best practices.
NEW QUESTION # 60
Refer to the exhibits.
An admin has created a WLAN that uses the settings shown in the exhibits (and has not otherwise adjusted the settings in the AAA profile). A client connects to the WLAN. Under which circumstances will a client receive the default role assignment?
A. The client has attempted 802.1X authentication, but the MC could not contact the authentication server.
B. The client has attempted 802.1X authentication, but failed to maintain a reliable connection, leading to a timeout error.
C. The client has passed 802.1X authentication, and the value in the Aruba-User-Role VSA matches a role on the MC.
D. The client has passed 802.1X authentication, and the authentication server did not send an Aruba-User-Role VSA.
Answer: D
Explanation:
The exhibit shows the configuration of a WLAN on an AOS-8 Mobility Controller (MC) with the following settings:
Key management: WPA3-Enterprise (indicating 802.1X authentication).
Use CNSA suite: Unchecked (using standard encryption, not the Commercial National Security Algorithm suite).
Key size: 128 bits (standard for AES-GCMP in WPA3).
Reauth interval: 1440 minutes (24 hours, the interval for re-authentication).
Machine authentication: Disabled (only user authentication is required).
Blacklisting: Disabled (clients are not blacklisted after failed attempts).
The question states that the AAA profile settings have not been adjusted, meaning the default roles (e.g., initial role, logon role, 802.1X default role) are not specified in the exhibit and are assumed to be the system defaults (e.g., "logon" for the initial and logon roles, and a default role like "guest" for the 802.1X default role). The question asks under which circumstances a client will receive the "default role assignment," which refers to the 802.1X default role configured in the AAA profile for the WLAN.
802.1X Authentication Process in AOS-8:
When a client connects to a WPA3-Enterprise WLAN, it starts in the initial role (typically "logon") to allow basic connectivity (e.g., DHCP, DNS).
During 802.1X authentication, the client is placed in the logon role to allow communication with the authentication server (e.g., ClearPass Policy Manager, CPPM).
If authentication succeeds, the client is assigned a role:
If the authentication server (e.g., CPPM) sends an Aruba-User-Role VSA with a role that exists on the MC, the client is assigned that role.
If no Aruba-User-Role VSA is sent, the client is assigned the 802.1X default role configured in the AAA profile for the WLAN.
If authentication fails or the server is unreachable, the client may be assigned a different role (e.g., a critical role, if configured) or denied access.
Option A, "The client has attempted 802.1X authentication, but the MC could not contact the authentication server," is incorrect. If the MC cannot contact the authentication server (e.g., due to a timeout), the client does not receive the 802.1X default role. Instead, the MC may apply a critical role (if configured) or deny access, depending on the configuration. The 802.1X default role is applied only after successful authentication.
Option B, "The client has passed 802.1X authentication, and the authentication server did not send an Aruba-User-Role VSA," is correct. If the client successfully authenticates via 802.1X and the authentication server (e.g., CPPM) does not send an Aruba-User-Role VSA, the MC assigns the client the 802.1X default role configured in the AAA profile for the WLAN. This is the "default role assignment" referred to in the question.
Option C, "The client has attempted 802.1X authentication, but failed to maintain a reliable connection, leading to a timeout error," is incorrect. A timeout error during authentication (e.g., the client fails to respond to EAP messages) typically results in an authentication failure, not a successful authentication. The client would not receive the 802.1X default role; it might be denied access or placed in a different role (e.g., a pre-authentication role).
Option D, "The client has passed 802.1X authentication, and the value in the Aruba-User-Role VSA matches a role on the MC," is incorrect. If the authentication server sends an Aruba-User-Role VSA with a role that exists on the MC, the client is assigned that specific role, not the 802.1X default role.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"After a client successfully authenticates via 802.1X, the Mobility Controller assigns a role to the client. If the authentication server (e.g., a RADIUS server) sends an Aruba-User-Role VSA with a role that exists on the controller, the client is assigned that role. If no Aruba-User-Role VSA is sent in the Access-Accept message, the client is assigned the 802.1X default role configured in the AAA profile for the WLAN. For example, if the AAA profile specifies 'guest' as the 802.1X default role, the client will be assigned the 'guest' role." (Page 305, Role Assignment Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"In WPA3-Enterprise with 802.1X authentication, the default role assignment occurs when a client successfully authenticates but the authentication server does not specify a role via the Aruba-User-Role VSA. In this case, the client receives the 802.1X default role defined in the AAA profile, such as 'guest' or another role configured by the administrator." (Page 42, 802.1X Role Assignment Section)

NEW QUESTION # 61
What is a reason to set up a packet capture on an Aruba Mobility Controller (MC)?
A. You want the MC to analyze wireless clients' traffic at a lower level, so that the ArubaOS firewall can control the traffic I based on application.
B. The company wants to use ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.
C. You want the MC to analyze wireless clients' traffic at a lower level, so that the ArubaOS firewall can control Web traffic based on the destination URL.
D. The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.
Answer: D
Explanation:
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.

NEW QUESTION # 63
What is an example or phishing?
A. An attacker lures clients to connect to a software-based AP that is using a legitimate SSID.
B. An attacker sends TCP messages to many different ports to discover which ports are open.
C. An attacker checks a user's password by using trying millions of potential passwords.
D. An attacker sends emails posing as a service team member to get users to disclose their passwords.
Answer: D
Explanation:
Phishing is a type of social engineering attack where an attacker impersonates a trusted entity to deceive people into providing sensitive information, such as passwords or credit card numbers. An example of phishing is when an attacker sends emails posing as a service team member or a legitimate organization with the intention of getting users to disclose their passwords or other confidential information. These emails often contain links to fake websites that look remarkably similar to legitimate ones, tricking users into entering their details.References:
