HP Aruba Certified Network Security Associate Exam Sample Questions (Q158-Q163):

NEW QUESTION # 158
What is one way that Control Plane Security (CPsec) enhances security for me network?

A. It prevents Denial of Service (DoS) attacks against Mobility Controllers' (MCs") control plane.
B. It prevents access from unauthorized IP addresses to critical services, such as SSH on Mobility Controllers (MCs).
C. It protects wireless clients' traffic tunneled between APs and Mobility Controllers, from eavesdropping
D. It protects management traffic between APs and Mobility Controllers (MCs) from eavesdropping.

Answer: D

Explanation:
Control Plane Security (CPsec) enhances security in the network by protecting management traffic between APs and Mobility Controllers (MCs) from eavesdropping. CPsec ensures that all control and management traffic that transits the network is encrypted, thus preventing potential attackers from gaining access to sensitive management data. It helps in securing the network's control plane, which is crucial for maintaining the integrity and privacy of the network operations.References:
Aruba Networks' CPsec documentation.

NEW QUESTION # 159
What is an example of passive endpoint classification?

A. SSH scans
B. WMI scans
C. SNMP scans
D. TCP fingerprinting

Answer: D

Explanation:
Endpoint classification in HPE Aruba Networking ClearPass Policy Manager (CPPM) involves identifying and categorizing devices on the network to enforce access policies. CPPM supports two types of profiling methods: passive and active.
Passive Profiling: Involves observing network traffic that devices send as part of their normal operation, without CPPM sending any requests to the device. Examples include DHCP fingerprinting, HTTP User-Agent analysis, and TCP fingerprinting.
Active Profiling: Involves CPPM sending requests to the device to gather information, such as SNMP scans, WMI scans, or SSH probes.
Option A, "TCP fingerprinting," is correct. TCP fingerprinting is a passive profiling method where CPPM analyzes TCP packet headers (e.g., TTL, window size) in the device's normal network traffic to identify its operating system. This does not require CPPM to send any requests to the device, making it a passive method.
Option B, "SSH scans," is incorrect. SSH scans involve actively connecting to a device over SSH to gather information (e.g., system details), which is an active profiling method.
Option C, "WMI scans," is incorrect. Windows Management Instrumentation (WMI) scans involve CPPM querying a Windows device to gather information (e.g., OS version, installed software), which is an active profiling method.
Option D, "SNMP scans," is incorrect. SNMP scans involve CPPM sending SNMP requests to a device to gather information (e.g., system description, interfaces), which is an active profiling method.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"Passive profiling methods observe network traffic that endpoints send as part of their normal operation, without ClearPass sending any requests to the device. An example of passive profiling is TCP fingerprinting, where ClearPass analyzes TCP packet headers (e.g., TTL, window size) to identify the device's operating system. Active profiling methods, such as SNMP scans, WMI scans, or SSH scans, involve ClearPass sending requests to the device to gather information." (Page 246, Passive vs. Active Profiling Section) Additionally, the ClearPass Device Insight Data Sheet notes:
"Passive profiling techniques, such as TCP fingerprinting, allow ClearPass to identify devices without generating additional network traffic. By analyzing TCP attributes in the device's normal traffic, ClearPass can fingerprint the OS, making it a non-intrusive method for endpoint classification." (Page 3, Profiling Methods Section)

NEW QUESTION # 160
You need to implement a WPA3-Enterprise network that can also support WPA2-Enterprise clients. What is a valid configuration for the WPA3-Enterprise WLAN?

A. CNSA mode disabled with 128-bit keys
B. CNSA mode enabled with 256-bit keys
C. CNSA mode disabled with 256-bit keys
D. CNSA mode enabled with 128-bit keys

Answer: C

Explanation:
In an Aruba network, when setting up a WPA3-Enterprise network that also supports WPA2-Enterprise clients, you would typically configure the network to operate in a transitional mode that supports both protocols. CNSA (Commercial National Security Algorithm) mode is intended for networks that require higher security standards as specified by the US National Security Agency (NSA). However, for compatibility with WPA2 clients, which do not support CNSA requirements, you would disable CNSA mode. WPA3 can use 256-bit encryption keys, which offer a higher level of security than the 128-bit keys used in WPA2.

NEW QUESTION # 161
Refer to the exhibit.

You have set up a RADIUS server on an ArubaOS Mobility Controller (MC) when you created a WLAN named "MyEmployees .You now want to enable the MC to accept change of authorization (CoA) messages from this server for wireless sessions on this WLAN.
What Is a part of the setup on the MC?

A. Create a dynamic authorization, or RFC 3576, server with the 10.5.5.5 address and correct shared secret.
B. Configure a ClearPass username and password in the MyEmployees AAA profile.
C. Enable the dynamic authorization setting in the "clearpass" authentication server settings.
D. Install the root CA associated with the 10 5.5.5 server's certificate as a Trusted CA certificate.

Answer: D

NEW QUESTION # 162
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 certificate lacks a valid SAN, and the client does not have the correct trusted CA certificates.
B. The certificate lacks the correct EKU.
C. The certificate lacks a valid SAN.
D. The client does not have the correct trusted CA certificates.

Answer: D

Explanation:
When a client (e.g., a Chrome browser) accesses an HTTPS server, the server presents a certificate to establish a secure connection. The client must validate the certificate to trust the server. The certificate in this scenario has the following properties:
Subject name: myhost.example.com
SAN (Subject Alternative Name): DNS: myhost.example.com; DNS: myhost1.example.com Extended Key Usage (EKU): Server authentication Issuer: MyCA_Signing (an intermediate CA) The server also sends an intermediate CA certificate for MyCA_Signing, signed by MyCA (the root CA).
The client's Trusted CA Certificate list does not include MyCA or MyCA_Signing.
Certificate Validation Process:
Name Validation: The client checks if the server's hostname (myhost1.example.com) matches the Subject name or a SAN in the certificate. Here, the SAN includes "myhost1.example.com," so the name validation passes.
EKU Validation: The client verifies that the certificate's EKU includes "Server authentication," which is required for HTTPS. The EKU is correctly set to "Server authentication," so this validation passes.
Chain of Trust Validation: The client builds a certificate chain from the server's certificate to a trusted root CA in its Trusted CA Certificate list. The chain is:
Server certificate (issued by MyCA_Signing)
Intermediate CA certificate (MyCA_Signing, issued by MyCA)
Root CA certificate (MyCA, which should be in the client's trust store) The client's Trusted CA Certificate list does not include MyCA or MyCA_Signing, meaning the client cannot build a chain to a trusted root CA. This causes the validation to fail.
Option A, "The client does not have the correct trusted CA certificates," is correct. The client's trust store must include the root CA (MyCA) to trust the certificate chain. Since MyCA is not in the client's Trusted CA Certificate list, the client cannot validate the chain, and the certificate is not trusted.
Option B, "The certificate lacks a valid SAN," is incorrect. The SAN includes "myhost1.example.com," which matches the server's hostname, so the SAN is valid.
Option C, "The certificate lacks the correct EKU," is incorrect. The EKU is set to "Server authentication," which is appropriate for HTTPS.
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, as explained above. 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."
