HP Aruba Certified Network Security Associate Exam Sample Questions (Q161-Q166):NEW QUESTION # 161
What is one practice that can help you to maintain a digital chain of custody in your network?
A. Ensure that all network infrastructure devices receive a valid clock using authenticated NTP.
B. Ensure that all network infrastructure devices use RADIUS rather than TACACS+ to authenticate managers.
C. Enable packet capturing on Instant AP or Mobility Controller (MC) datapath on an ongoing basis.
D. Enable packet capturing on Instant AP or Mobility Controller (MC) controlpath on an ongoing basis.
Answer: A
Explanation:
A digital chain of custody ensures that evidence (e.g., logs, timestamps) collected from a network can be reliably used in legal or forensic investigations. It requires maintaining the integrity and authenticity of data, including accurate timestamps for events. HPE Aruba Networking devices, such as Instant APs, Mobility Controllers (MCs), and AOS-CX switches, support features to help maintain a digital chain of custody.
Option C, "Ensure that all network infrastructure devices receive a valid clock using authenticated NTP," is correct. Accurate and synchronized time across all network devices is critical for maintaining a digital chain of custody. Timestamps in logs (e.g., authentication events, traffic logs) must be consistent and verifiable. Network Time Protocol (NTP) is used to synchronize device clocks, and authenticated NTP ensures that the time source is trusted and not tampered with (e.g., using MD5 or SHA authentication). This practice ensures that logs from different devices can be correlated accurately during an investigation.
Option A, "Enable packet capturing on Instant AP or Mobility Controller (MC) datapath on an ongoing basis," is incorrect. While packet capturing on the datapath (user traffic) can provide detailed traffic data for analysis, enabling it on an ongoing basis is impractical due to storage and performance constraints. Packet captures are typically used for specific troubleshooting or investigations, not for maintaining a chain of custody.
Option B, "Ensure that all network infrastructure devices use RADIUS rather than TACACS+ to authenticate managers," is incorrect. The choice of RADIUS or TACACS+ for manager authentication does not directly impact the digital chain of custody. Both protocols can log authentication events, but the protocol used does not ensure the integrity of timestamps or evidence.
Option D, "Enable packet capturing on Instant AP or Mobility Controller (MC) controlpath on an ongoing basis," is incorrect for similar reasons as Option A. Control path (control plane) packet captures include management traffic (e.g., between APs and MCs), but enabling them continuously is not practical and does not directly contribute to maintaining a chain of custody. Accurate timestamps in logs are more relevant.
The HPE Aruba Networking Security Guide states:
"Maintaining a digital chain of custody requires ensuring the integrity and authenticity of network logs and events. A critical practice is to ensure that all network infrastructure devices, such as Mobility Controllers and AOS-CX switches, receive a valid and synchronized clock using authenticated NTP. Use the command ntp server <ip-address> key <key-id> to configure authenticated NTP, ensuring that timestamps in logs are accurate and verifiable for forensic investigations." (Page 85, Digital Chain of Custody Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"Accurate time synchronization is essential for maintaining a digital chain of custody. Configure all devices to use authenticated NTP to synchronize their clocks with a trusted time source. This ensures that event logs, such as authentication and traffic logs, have consistent and reliable timestamps, which can be correlated across devices during an investigation."

NEW QUESTION # 162
A company has added a new user group. Users in the group try to connect to the WLAN and receive errors that the connection has no Internet access. The users cannot reach any resources. The first exhibit shows the record for one of the users who cannot connect. The second exhibit shows the role to which the ArubaOS device assigned the user's client.
What is a likely problem?
A. The ArubaOS device does not have the correct RADIUS dictionaries installed on it to under-stand the Aruba-User-Role VSA.
B. The ArubaOS device has a server derivation rule configured on it that has overridden the role sent by CPPM.
C. The role name that CPPM is sending does not match the role name configured on the Aru-baOS device.
D. The clients rejected the server authentication on their side because they do not have the root CA for CPPM's RADIUS/EAP certificate.
Answer: C
Explanation:
The image indicates that there is an issue with the user role assignment, which is key to network access in ArubaOS. If the user role name sent by CPPM doesn't match any of the roles defined in the ArubaOS, then the user will be assigned a default or incorrect role that does not have the necessary permissions, thus leading to the connection errors and lack of Internet access. Ensuring that the role names are consistent between CPPM and ArubaOS can resolve this issue.
NEW QUESTION # 163
What is a correct guideline for the management protocols that you should use on AOS-CX switches?
A. Make sure that SSH is disabled and use HTTPS instead.
B. Make sure that Telnet is disabled and use TFTP instead.
C. Make sure that Telnet is disabled and use SSH instead.
D. Make sure that HTTPS is disabled and use SSH instead.
Answer: C
Explanation:
AOS-CX switches support various management protocols for administrative access, such as SSH, Telnet, HTTPS, and TFTP. Security best practices for managing network devices, including AOS-CX switches, emphasize using secure protocols to protect management traffic from eavesdropping and unauthorized access.
Option B, "Make sure that Telnet is disabled and use SSH instead," is correct. Telnet is an insecure protocol because it sends all data, including credentials, in plaintext, making it vulnerable to eavesdropping. SSH (Secure Shell) provides encrypted communication for remote management, ensuring that credentials and commands are protected. HPE Aruba Networking recommends disabling Telnet and enabling SSH for secure management access on AOS-CX switches.
Option A, "Make sure that SSH is disabled and use HTTPS instead," is incorrect. SSH and HTTPS serve different purposes: SSH is for CLI access, while HTTPS is for web-based management. Disabling SSH would prevent secure CLI access, which is not a recommended practice. Both SSH and HTTPS should be enabled for secure management.
Option C, "Make sure that Telnet is disabled and use TFTP instead," is incorrect. TFTP (Trivial File Transfer Protocol) is used for file transfers (e.g., firmware updates), not for management access like Telnet or SSH. TFTP is also insecure (no encryption), so it's not a suitable replacement for Telnet.
Option D, "Make sure that HTTPS is disabled and use SSH instead," is incorrect. HTTPS is used for secure web-based management and should not be disabled. Both HTTPS and SSH are secure protocols and should be used together for different management interfaces (web and CLI, respectively).
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"For secure management of AOS-CX switches, disable insecure protocols like Telnet, which sends data in plaintext, and use SSH instead. SSH provides encrypted communication for CLI access, protecting credentials and commands from eavesdropping. Use the command no telnet-server to disable Telnet and ssh-server to enable SSH. Additionally, enable HTTPS for web-based management with https-server to ensure all management traffic is encrypted." (Page 195, Secure Management Protocols Section) Additionally, the HPE Aruba Networking Security Best Practices Guide notes:
"A key guideline for managing AOS-CX switches is to disable Telnet and enable SSH for CLI access. Telnet is insecure and should not be used in production environments, as it transmits credentials in plaintext. SSH ensures secure remote management, and HTTPS should also be enabled for web access."

NEW QUESTION # 164
A company has HPE Aruba Networking Mobility Controllers (MCs), campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other HPE Aruba Networking ClearPass solutions.
The HPE Aruba Networking ClearPass admins tell you that they want to use HTTP User-Agent strings to help profile the endpoints.
What should you do as a part of setting up Mobility Controllers (MCs) to support this requirement?
A. Create a firewall whitelist rule that permits HTTP and CPPM's IP address.
B. Create control path mirrors to mirror HTTP traffic from clients to CPPM.
C. Create datapath mirrors that use the CPPM's IP address as the destination.
D. Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM.
Answer: C
Explanation:
HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to classify endpoints, and one of its profiling methods involves analyzing HTTP User-Agent strings to identify device types (e.g., iPhone, Windows laptop). HTTP User-Agent strings are sent in HTTP headers when a client accesses a website. For CPPM to profile devices using HTTP User-Agent strings, it must receive the HTTP traffic from the clients. In this scenario, the company is using Mobility Controllers (MCs), campus APs, and AOS-CX switches, and CPPM is the only ClearPass solution in use.
HTTP User-Agent Profiling: CPPM can passively profile devices by analyzing HTTP traffic, but it needs to receive this traffic. In an AOS-8 architecture, the MC can mirror client traffic to CPPM for profiling. Since HTTP traffic is part of the data plane (user traffic), the MC must mirror the data plane traffic (not control plane traffic) to CPPM.
Option A, "Create datapath mirrors that use the CPPM's IP address as the destination," is correct. The MC can be configured to mirror client HTTP traffic to CPPM using a datapath mirror (also known as a GRE mirror). This involves setting up a mirror session on the MC that sends a copy of the client's HTTP traffic to CPPM's IP address. CPPM then analyzes the HTTP User-Agent strings in this traffic to profile the endpoints. For example, the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http can be used to mirror HTTP traffic to CPPM.
Option B, "Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM," is incorrect. IF-MAP (Interface for Metadata Access Points) is a protocol used for sharing profiling data between ClearPass and other systems (e.g., Aruba Introspect), but it is not used for sending HTTP traffic to CPPM for profiling. Additionally, IF-MAP is not relevant when only CPPM is in use.
Option C, "Create control path mirrors to mirror HTTP traffic from clients to CPPM," is incorrect. Control path (control plane) traffic includes management traffic between the MC and APs (e.g., AP registration, heartbeats), not client HTTP traffic. HTTP traffic is part of the data plane, so a datapath mirror is required, not a control path mirror.
Option D, "Create a firewall whitelist rule that permits HTTP and CPPM's IP address," is incorrect. A firewall whitelist rule on the MC might be needed to allow traffic to CPPM, but this is not the primary step for enabling HTTP User-Agent profiling. The key requirement is to mirror the HTTP traffic to CPPM, which is done via a datapath mirror, not a firewall rule.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"To enable ClearPass Policy Manager (CPPM) to profile devices using HTTP User-Agent strings, the Mobility Controller (MC) must mirror client HTTP traffic to CPPM. This is done by creating a datapath mirror session that sends a copy of the client's HTTP traffic to CPPM's IP address. For example, use the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http to mirror HTTP traffic to CPPM. CPPM then analyzes the HTTP User-Agent strings to classify endpoints by type (e.g., iPhone, Windows laptop)." (Page 350, Device Profiling with CPPM Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
"HTTP User-Agent profiling requires ClearPass to receive HTTP traffic from clients. In an Aruba Mobility Controller environment, configure a datapath mirror to send HTTP traffic to ClearPass's IP address. ClearPass will parse the HTTP User-Agent strings to identify device types and operating systems, enabling accurate profiling." (Page 249, HTTP User-Agent Profiling Section)

NEW QUESTION # 165
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. 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.
C. The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.
D. The company wants to use ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.
Answer: C
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.
