HP Aruba Certified Network Security Associate Exam Sample Questions (Q41-Q46):

NEW QUESTION # 41
Refer to the exhibit.

A diem is connected to an ArubaOS Mobility Controller. The exhibit snows all Tour firewall rules that apply to this diem What correctly describes how the controller treats HTTPS packets to these two IP addresses, both of which are on the other side of the firewall
10.1 10.10
203.0.13.5

  • A. It drops the packet to 10.1.10.10 and permits the packet to 203.0.13.5.
  • B. it permits both of the packets
  • C. It permits the packet to 10.1.10.10 and drops the packet to 203 0.13.5
  • D. It drops both of the packets

Answer: C

Explanation:
Referring to the exhibit, the ArubaOS Mobility Controller treats HTTPS packets based on the firewall rules applied to the client. The rule that allows svc-https service for destination IP range 10.1.0.0 255.255.0.0 would permit an HTTPS packet to 10.1.10.10 since this IP address falls within the specified range. There are no rules shown that would allow traffic to the IP address 203.0.13.5; hence, the packet to this address would be dropped.

Network security textbooks explaining firewall rule processing and packet filtering based on source and destination IP addresses.


NEW QUESTION # 42
You have configured a WLAN to use Enterprise security with the WPA3 version.
How does the WLAN handle encryption?

  • A. Traffic is encrypted with TKIP and keys derived from a PMK shared by all clients on the WLAN.
  • B. Traffic is encrypted with TKIP and keys derived from a unique PMK per client.
  • C. Traffic is encrypted with AES and keys derived from a unique PMK per client.
  • D. Traffic is encrypted with AES and keys derived from a PMK shared by all clients on the WLAN.

Answer: C

Explanation:
WPA3-Enterprise is a security protocol introduced to enhance the security of wireless networks, particularly in enterprise environments. It builds on the foundation of WPA2 but introduces stronger encryption and key management practices. In WPA3-Enterprise, authentication is typically performed using 802.1X, and encryption is handled using the Advanced Encryption Standard (AES).
WPA3-Enterprise Encryption: WPA3-Enterprise uses AES with the Galois/Counter Mode Protocol (GCMP) or Cipher Block Chaining Message Authentication Code Protocol (CCMP), both of which are AES-based encryption methods. WPA3 does not use TKIP (Temporal Key Integrity Protocol), which is a legacy encryption method used in WPA and early WPA2 deployments and is considered insecure.
Pairwise Master Key (PMK): In WPA3-Enterprise, the PMK is derived during the 802.1X authentication process (e.g., via EAP-TLS or EAP-TTLS). Each client authenticates individually with the authentication server (e.g., ClearPass), resulting in a unique PMK for each client. This PMK is then used to derive session keys (Pairwise Transient Keys, PTKs) for encrypting the client's traffic, ensuring that each client's traffic is encrypted with unique keys.
Option A, "Traffic is encrypted with TKIP and keys derived from a PMK shared by all clients on the WLAN," is incorrect because WPA3 does not use TKIP (it uses AES), and the PMK is not shared among clients in WPA3-Enterprise; each client has a unique PMK.
Option B, "Traffic is encrypted with TKIP and keys derived from a unique PMK per client," is incorrect because WPA3 does not use TKIP; it uses AES.
Option C, "Traffic is encrypted with AES and keys derived from a PMK shared by all clients on the WLAN," is incorrect because, in WPA3-Enterprise, the PMK is unique per client, not shared.
Option D, "Traffic is encrypted with AES and keys derived from a unique PMK per client," is correct. WPA3-Enterprise uses AES for encryption, and each client derives a unique PMK during 802.1X authentication, which is used to generate unique session keys for encryption.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"WPA3-Enterprise enhances security by using AES encryption with GCMP or CCMP. In WPA3-Enterprise mode, each client authenticates via 802.1X, resulting in a unique Pairwise Master Key (PMK) for each client. The PMK is used to derive session keys (Pairwise Transient Keys, PTKs) that encrypt the client's traffic with AES, ensuring that each client's traffic is protected with unique keys. WPA3 does not support TKIP, which is a legacy encryption method." (Page 285, WPA3-Enterprise Security Section) Additionally, the HPE Aruba Networking Wireless Security Guide notes:
"WPA3-Enterprise requires 802.1X authentication, which generates a unique PMK for each client. This PMK is used to derive AES-based session keys, providing individualized encryption for each client's traffic and eliminating the risks associated with shared keys."

NEW QUESTION # 43
What is a benefit or Protected Management Frames (PMF). sometimes called Management Frame Protection (MFP)?

  • A. PMF helps to protect APs and MCs from unauthorized management access by hackers.
  • B. PMF protects clients from DoS attacks based on forged de-authentication frames
  • C. PMF prevents hackers from capturing the traffic between APs and Mobility Controllers.
  • D. PMF ensures trial traffic between APs and Mobility Controllers (MCs) is encrypted.

Answer: A


NEW QUESTION # 44
The monitoring admin has asked you to set up an ArubaOS-Switch to meet these criteria:
* Send logs to a SIEM Syslog server at 10.4.13.15 at the standard UDP port (514)
* Send a log for all events at the "warning" level or above
The switch did not have any "logging" configuration on it. You then entered this command:
ArubaOS-Switch(config)# logging 10.4.13.15 udp
What should you do to finish configuring to the requirements?

  • A. Configure logging as a debug destination.
  • B. Add categories (system-modules) at the global level.
  • C. Ask for the Syslog password and configure it on the switch.
  • D. Specify "warning" as the global level.

Answer: D

Explanation:
To set up an ArubaOS-Switch to send logs to a SIEM syslog server at the specified criteria, you would need to specify the level of events that should be logged. Since the requirement is to log all events at the "warning" level or above, you should specify the syslog level after the logging server IP and port. The command should look like this:
ArubaOS-Switch(config)# logging 10.4.13.15 ArubaOS-Switch(config)# logging trap warning This would set up the switch to send logs to the syslog server at the IP address 10.4.13.15 using the default UDP port (514), for all events at the "warning" level or above.


NEW QUESTION # 45
A client has accessed an HTTPS server at myhost1.example.com using Chrome. The server sends a certificate that includes these properties:
Subject name: myhost.example.com
SAN: DNS: myhost.example.com; DNS: myhost1.example.com
Extended Key Usage (EKU): Server authentication
Issuer: MyCA_Signing
The server also sends an intermediate CA certificate for MyCA_Signing, which is signed by MyCA. The client's Trusted CA Certificate list does not include the MyCA or MyCA_Signing certificates.
Which factor or factors prevent the client from trusting the certificate?

  • A. The client does not have the correct trusted CA certificates.
  • B. The certificate lacks a valid SAN.
  • C. The certificate lacks the correct EKU.
  • D. The certificate lacks a valid SAN, and the client does not have the correct trusted CA certificates.

Answer: A

Explanation:
This question is identical to Question 17, with the same certificate properties and scenario. The client (Chrome browser) accesses an HTTPS server at myhost1.example.com, and the server presents a certificate with:
Subject name: myhost.example.com
SAN: DNS: myhost.example.com; DNS: myhost1.example.com
EKU: Server authentication
Issuer: MyCA_Signing (intermediate CA)
The intermediate CA certificate (MyCA_Signing) is signed by MyCA (root CA).
The client's Trusted CA Certificate list does not include MyCA or MyCA_Signing.
The certificate validation process is the same as in Question 17:
Name Validation: The SAN includes "myhost1.example.com," which matches the server's hostname, so this passes.
EKU Validation: The EKU is "Server authentication," which is correct for HTTPS, so this passes.
Chain of Trust Validation: The client attempts to build a chain from the server's certificate to a trusted root CA:
Server certificate → MyCA_Signing → MyCA Since MyCA is not in the client's Trusted CA Certificate list, the chain cannot be validated, and the client does not trust the certificate.
Option A, "The client does not have the correct trusted CA certificates," is correct. The absence of MyCA in the client's trust store prevents the client from validating the certificate chain.
Option B, "The certificate lacks a valid SAN," is incorrect because the SAN includes "myhost1.example.com," which is valid.
Option C, "The certificate lacks the correct EKU," is incorrect because the EKU is correctly set to "Server authentication." Option D, "The certificate lacks a valid SAN, and the client does not have the correct trusted CA certificates," is incorrect because the SAN is valid; the only issue is the missing trusted CA certificates.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"For a client to trust a server's certificate during HTTPS communication, the client must validate the certificate chain to a trusted root CA in its trust store. If the root CA (e.g., MyCA) or intermediate CA (e.g., MyCA_Signing) is not in the client's Trusted CA Certificate list, the chain of trust cannot be established, and the client will reject the certificate. The Subject Alternative Name (SAN) must include the server's hostname, and the Extended Key Usage (EKU) must include 'Server authentication' for HTTPS." (Page 205, Certificate Validation Section) Additionally, the HPE Aruba Networking Security Fundamentals Guide notes:
"A common reason for certificate validation failure is the absence of the root CA certificate in the client's trust store. For example, if a server's certificate is issued by an intermediate CA (e.g., MyCA_Signing) that chains to a root CA (e.g., MyCA), the client must have the root CA certificate in its Trusted CA Certificate list to trust the chain."
