HP Aruba Certified Network Security Associate Exam Sample Questions (Q91-Q96):

NEW QUESTION # 91
You are setting up an Aruba mobility solution which includes a Mobility Master (MM), Mobility Controllers (MCs), and campus APs (CAPs) for a university. The university plans to enforce WPA2-Enterprise for all users' connections. The university wants to apply one set of access control rules to faculty users' traffic and a different set of rules to students' traffic.
What is the best approach for applying the correct rules to each group?

A. Create two VLANs, one for faculty and one for students. Apply firewall policies with the correct rules for each group to each VLAN.
B. Create two VLANs, one for faculty and one for students. Create one set of firewall access control rules that specify faculty IP addresses for the source and a second set of rules that specify the student IP addresses for the source. Apply the rules to the WLAN.
C. Create two roles, a "faculty" role and a "student" role. Apply firewall policies with the correct rules for each group to each role.
D. Create two WLANs, one for faculty and one for students. Apply firewall policies with the correct rules for each group to each WLAN.

Answer: C

Explanation:
To differentiate access control for faculty and students, the best approach is to use roles. By creating two roles - "faculty" and "student" - and applying the appropriate firewall policies to each, the university can enforce different access rules for each group. This is more efficient than managing multiple VLANs or WLANs because it allows for role-based access control, which is directly tied to user identity rather than just IP addresses or the network they are connected to.

NEW QUESTION # 92
How does the ArubaOS firewall determine which rules to apply to a specific client's traffic?

A. The firewall applies every rule that includes the client's IP address as the source or destination.
B. The firewall applies every rule that includes the dent's IP address as the source.
C. The firewall applies thee rules in policies associated with the client's user role.
D. The firewall applies the rules in policies associated with the client's wlan

Answer: C

Explanation:
The ArubaOS firewall determines which rules to apply to a specific client's traffic based on the rules in policies associated with the client's user role. User roles are a fundamental part of ArubaOS and the firewall policies they encompass. These roles contain policies that dictate permissions and restrictions for network traffic. When a client authenticates, it is assigned a role, and the firewall enforces the rules defined within that role for the client's traffic.

NEW QUESTION # 93
What is one way that WPA3-PerSonal enhances security when compared to WPA2-Personal?

A. WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password
B. WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least
12 characters
C. WPA3-Personal is more complicated to deploy because it requires a backend authentication server
D. WPA3-Personai prevents eavesdropping on other users' wireless traffic by a user who knows the passphrase for the WLAN.

Answer: D

Explanation:
WPA3-Personal enhances security over WPA2-Personal by implementing individualized data encryption.
This feature, known as Wi-Fi Enhanced Open, provides each user's session with a unique encryption key, even if they are using the same network passphrase. This prevents an authenticated user from eavesdropping on the traffic of other users on the same network, thus enhancing privacy and security.References:

NEW QUESTION # 94
What is a benefit of Opportunistic Wireless Encryption (OWE)?

A. It allows anyone to connect, but provides better protection against eavesdropping than a traditional open network.
B. It offers more control over who can connect to the wireless network when compared with WPA2-Personal.
C. It allows both WPA2-capable and WPA3-capable clients to authenticate to the same WPA-Personal WLAN.
D. It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MITM) attacks.

Answer: A

Explanation:
Opportunistic Wireless Encryption (OWE) is a WPA3 feature designed for open wireless networks, where no password or authentication is required to connect. OWE enhances security by providing encryption for devices that support it, without requiring a pre-shared key (PSK) or 802.1X authentication.
Option C, "It allows anyone to connect, but provides better protection against eavesdropping than a traditional open network," is correct. In a traditional open network (no encryption), all traffic is sent in plaintext, making it vulnerable to eavesdropping. OWE allows anyone to connect (as it's an open network), but it negotiates unique encryption keys for each client using a Diffie-Hellman key exchange. This ensures that client traffic is encrypted with AES (e.g., using AES-GCMP), protecting it from eavesdropping. OWE in transition mode also supports non-OWE devices, which connect without encryption, but OWE-capable devices benefit from the added security.
Option A, "It allows both WPA2-capable and WPA3-capable clients to authenticate to the same WPA-Personal WLAN," is incorrect. OWE is for open networks, not WPA-Personal (which uses a PSK). WPA2/WPA3 transition mode (not OWE) allows both WPA2 and WPA3 clients to connect to the same WPA-Personal WLAN.
Option B, "It offers more control over who can connect to the wireless network when compared with WPA2-Personal," is incorrect. OWE is an open network protocol, meaning it offers less control over who can connect compared to WPA2-Personal, which requires a PSK for access.
Option D, "It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MITM) attacks," is incorrect. OWE provides encryption to prevent eavesdropping, but it does not protect against honeypot APs (rogue APs broadcasting the same SSID) or MITM attacks, as it lacks authentication mechanisms to verify the AP's identity. Protection against such attacks requires 802.1X authentication (e.g., WPA3-Enterprise) or other security measures.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Opportunistic Wireless Encryption (OWE) is a WPA3 feature for open networks that allows anyone to connect without a password, but provides better protection against eavesdropping than a traditional open network. OWE uses a Diffie-Hellman key exchange to negotiate unique encryption keys for each client, ensuring that traffic is encrypted with AES-GCMP and protected from unauthorized interception." (Page 290, OWE Overview Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"OWE enhances security for open WLANs by providing encryption without requiring authentication. It allows any device to connect, but OWE-capable devices benefit from encrypted traffic, offering better protection against eavesdropping compared to a traditional open network where all traffic is sent in plaintext."

NEW QUESTION # 95
What is a guideline for managing local certificates on an ArubaOS-Switch?

A. Install an Online Certificate Status Protocol (OCSP) certificate to simplify the process of enrolling and re-enrolling for certificate
B. Create a self-signed certificate online on the switch because ArubaOS-Switches do not support CA-signed certificates.
C. Generate the certificate signing request (CSR) with a program offline, then, install both the certificate and the private key on the switch in a single file.
D. Before installing the local certificate, create a trust anchor (TA) profile with the root CA certificate for the certificate that you will install

Answer: D

Explanation:
When managing local certificates on an ArubaOS-Switch, a recommended guideline is to create a trust anchor (TA) profile with the root CA certificate before installing the local certificate. This step ensures that the switch can verify the authenticity of the certificate chain during SSL/TLS communications. The trust anchor profile establishes a basis of trust by containing the root CA certificate, which helps validate the authenticity of any subordinate certificates, including the local certificate installed on the switch. This process is essential for enhancing security on the network, as it ensures that encrypted communications involving the switch are based on a verified certificate hierarchy.

Security best practices and SSL/TLS implementation guidelines that emphasize the importance of establishing trusted certificate chains for secure communications.
