QUESTION 94
What is a reason to set up a packet capture on an HPE Aruba Networking Mobility Controller (MC)?

The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.

The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.

You want the MC to analyze wireless clients’ traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL.

You want the MC to analyze wireless clients’ traffic at a lower level, so that the AOS firewall can control the traffic based on application.

Packet captures on an HPE Aruba Networking Mobility Controller (MC) are a powerful troubleshooting and analysis tool, allowing administrators to capture and analyze network traffic at various levels (e.g., control plane or data plane). The MC supports packet captures for both wired and wireless traffic, which can be filtered based on criteria such as IP address, MAC address, or port.
Option A, “The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely,” is correct. Packet captures are commonly used in security investigations to analyze the traffic of a specific endpoint suspected of malicious activity. For example, if a wireless client is suspected of launching an attack (e.g., a DoS attack or data exfiltration), a packet capture on the MC can capture the client’s traffic (filtered by MAC or IP address) for detailed analysis, helping the security team identify the nature of the attack.
Option B, “The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC,” is incorrect. While CPPM can use HTTP User-Agent strings for device profiling, this is typically achieved by mirroring HTTP traffic to CPPM (e.g., using a datapath mirror on the MC), not by setting up a packet capture. Packet captures are for manual analysis, not for feeding data to CPPM.
Option C, “You want the MC to analyze wireless clients’ traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL,” is incorrect. The AOS firewall on the MC can control traffic based on applications or services (e.g., using deep packet inspection, DPI), but it does not support URL-based filtering directly. URL filtering typically requires an external solution (e.g., a web proxy or firewall). Packet captures are not used to enable URL-based control by the firewall.
Option D, “You want the MC to analyze wireless clients’ traffic at a lower level, so that the AOS firewall can control the traffic based on application,” is incorrect. The AOS firewall can already perform application-based control using DPI (if enabled), without requiring a packet capture. Packet captures are for manual analysis, not for enabling firewall functionality.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“Packet captures on the Mobility Controller are useful for troubleshooting and security investigations. For example, if the security team suspects that a wireless endpoint is launching an attack, you can set up a packet capture on the MC’s data plane to capture the endpoint’s traffic. Use the command packet-capture datapath <filter> (e.g., filter by the client’s MAC address) to capture the traffic, which can then be analyzed to identify malicious activity.” (Page 515, Packet Capture Section) Additionally, the HPE Aruba Networking Security Guide notes:
“Packet captures are a critical tool for security teams to investigate potential attacks. By capturing traffic from a specific wireless client suspected of malicious behavior, administrators can analyze the packets to determine the nature of the attack, such as a DoS attack or unauthorized data exfiltration.” (Page 65, Security Troubleshooting Section)

QUESTION 95
Why might devices use a Diffie-Hellman exchange?

to agree on a shared secret in a secure manner over an insecure network

to obtain a digital certificate signed by a trusted Certification Authority

to prove knowledge of a passphrase without transmitting the passphrase

to signal that they want to use asymmetric encryption for future communications

QUESTION 96
Refer to the exhibit.

You are deploying a new ArubaOS Mobility Controller (MC), which is enforcing authentication to Aruba ClearPass Policy Manager (CPPM). The authentication is not working correctly, and you find the error shown In the exhibit in the CPPM Event Viewer.
What should you check?

that the MC has been added as a domain machine on the Active Directory domain with which CPPM is synchronized

that the snared secret configured for the CPPM authentication server matches the one defined for the device on CPPM

that the IP address that the MC is using to reach CPPM matches the one defined for the device on CPPM

that the MC has valid admin credentials configured on it for logging into the CPPM

QUESTION 97
What is one practice that can help you to maintain a digital chain of custody in your network?

Enable packet capturing on Instant AP or Mobility Controller (MC) datapath on an ongoing basis.

Ensure that all network infrastructure devices use RADIUS rather than TACACS+ to authenticate managers.

Ensure that all network infrastructure devices receive a valid clock using authenticated NTP.

Enable packet capturing on Instant AP or Mobility Controller (MC) controlpath on an ongoing basis.

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.” (Page 380, Time Synchronization Section)

QUESTION 98
What distinguishes a Distributed Denial of Service (DDoS) attack from a traditional Denial or service attack (DoS)?

A DDoS attack originates from external devices, while a DoS attack originates from internal devices

A DDoS attack is launched from multiple devices, while a DoS attack is launched from a single device

A DoS attack targets one server, a DDoS attack targets all the clients that use a server

A DDoS attack targets multiple devices, while a DoS Is designed to Incapacitate only one device

QUESTION 99
A company has HPE Aruba Networking Mobility Controllers (MCs), HPE Aruba Networking campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. The company is contemplating the use of ClearPass’s TCP fingerprinting capabilities.
What is a consideration for using those capabilities?

You will need to mirror traffic to one of CPPM’s span ports from a device such as a core routing switch.

ClearPass admins will need to provide the credentials of an API admin account to configure on HPE Aruba Networking devices.

AOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints.

TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution.

HPE Aruba Networking ClearPass Policy Manager (CPPM) uses TCP fingerprinting as a passive profiling method to classify endpoints by analyzing TCP packet headers (e.g., TTL, window size) to identify the operating system (e.g., Windows, Linux). The company in this scenario has Mobility Controllers (MCs), campus APs, and AOS-CX switches, and wants to use CPPM’s TCP fingerprinting capabilities for endpoint classification.
TCP Fingerprinting: This method requires CPPM to receive TCP traffic from endpoints. Since CPPM is not typically inline with network traffic, the traffic must be mirrored to CPPM for analysis. This is often done using a SPAN (Switched Port Analyzer) port or mirror port on a switch or controller.
Option A, “You will need to mirror traffic to one of CPPM’s span ports from a device such as a core routing switch,” is correct. For CPPM to perform TCP fingerprinting, it needs to see the TCP traffic from endpoints. This is typically achieved by mirroring traffic from a core routing switch (or another device like an MC) to a SPAN port on the CPPM server. For example, on an AOS-CX switch, you can configure a mirror session with the command mirror session 1 destination interface <CPPM-port> source vlan <vlan-id> to send traffic to CPPM. This is a key consideration for enabling TCP fingerprinting.
Option B, “ClearPass admins will need to provide the credentials of an API admin account to configure on HPE Aruba Networking devices,” is incorrect. TCP fingerprinting does not require API credentials. It is a passive profiling method that analyzes mirrored traffic, and no API interaction is needed between CPPM and Aruba devices for this purpose.
Option C, “AOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints,” is incorrect. AOS-CX switches support mirroring traffic to CPPM (e.g., using a mirror session), which enables CPPM to perform TCP fingerprinting on wired endpoints. The switch does not need to perform the fingerprinting itself; it only needs to send the traffic to CPPM.
Option D, “TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution,” is incorrect. TCP fingerprinting is a built-in capability of CPPM and does not require an MDM solution. For wireless endpoints, the MC can mirror client traffic to CPPM (e.g., using a datapath mirror), allowing CPPM to perform TCP fingerprinting.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
“TCP fingerprinting requires ClearPass to receive TCP traffic from endpoints for analysis. A key consideration is that you must mirror traffic to one of ClearPass’s SPAN ports from a device such as a core routing switch or Mobility Controller. For example, on an AOS-CX switch, configure a mirror session with mirror session 1 destination interface <CPPM-port> source vlan <vlan-id> to send traffic to ClearPass for TCP fingerprinting.” (Page 248, TCP Fingerprinting Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
“For ClearPass to perform TCP fingerprinting on wireless endpoints, the Mobility Controller can mirror client traffic to ClearPass using a datapath mirror. For wired endpoints, an AOS-CX switch can mirror traffic to ClearPass’s SPAN port, enabling TCP fingerprinting without requiring additional support on the switch itself.” (Page 351, Device Profiling with CPPM Section)

QUESTION 100
What is a vulnerability of an unauthenticated Dime-Heliman exchange?

A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.

A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values

Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.

Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.

QUESTION 101
What is a benefit of Opportunistic Wireless Encryption (OWE)?

It allows both WPA2-capabie and WPA3-capable clients to authenticate to the same WPA-Personal WLAN

It offers more control over who can connect to the wireless network when compared with WPA2-Personal

It allows anyone lo connect, but provides better protection against eavesdropping than a traditional open network

It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MUM) attacks

QUESTION 102
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?

Create a dynamic authorization, or RFC 3576, server with the 10.5.5.5 address and correct shared secret.

Install the root CA associated with the 10 5.5.5 server’s certificate as a Trusted CA certificate.

Configure a ClearPass username and password in the MyEmployees AAA profile.

Enable the dynamic authorization setting in the “clearpass” authentication server settings.

QUESTION 103
Two wireless clients, client 1 and client 2, are connected to an ArubaOS Mobility Controller. Subnet 10.1.10.10/24 is a network of servers on the other side of the ArubaOS firewall. The exhibit shows all three firewall rules that apply to these clients.
Which traffic is permitted?

an HTTPS request from client 1 to 10.1.10.10 and an HTTPS response from 10.1.10.10 to client 1

an HTTPS request from client 1 to 10.1.10.10 and an HTTPS request from 10.1.10.11 to client 1

an HTTPS request from 10.1.10.10 to client 1 and an HTTPS re-sponse from client 1 to 10.1.10.10

an HTTPS request from client 1 to client 2 and an HTTPS request from client 2 to client 1

QUESTION 104
What is a difference between radius and TACACS+?

RADIUS combines the authentication and authorization process while TACACS+ separates them.

RADIUS uses TCP for Its connection protocol, while TACACS+ uses UDP tor its connection protocol.

RADIUS encrypts the complete packet, white TACACS+ only offers partial encryption.

RADIUS uses Attribute Value Pairs (AVPs) in its messages, while TACACS+ does not use them.

QUESTION 105
What is a reason to set up a packet capture on an Aruba Mobility Controller (MC)?

The company wants to use ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.

The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.

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.

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.

QUESTION 106
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?

The client does not have the correct trusted CA certificates.

The certificate lacks a valid SAN.

The certificate lacks the correct EKU.

The certificate lacks a valid SAN, and the client does not have the correct trusted CA certificates.

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.” (Page 45, Certificate Trust Issues Section)

QUESTION 107
What is a guideline for creating certificate signing requests (CSRs) and deploying server Certificates on ArubaOS Mobility Controllers (MCs)?

Create the CSR online using the MC Web Ul if your company requires you to archive the private key.

if you create the CSR and public/private Keypair offline, create a matching private key online on the MC.

Create the CSR and public/private keypair offline If you want to install the same certificate on multiple MCs.

Generate the private key online, but the public key and CSR offline, to install the same certificate on multiple MCs.

What is one benefit of adding Aruba Airwave from the perspective of forensics?

Airwave can provide more advanced authentication and access control services for the AmbaOS solution

Airwave retains information about the network for much longer periods than ArubaOS solution

Airwave is required to activate Wireless Intrusion Prevention (WIP) services on the ArubaOS solution

AirWave enables low level debugging on the devices across the ArubaOS solution

QUESTION 111
What is a benefit of deploying HPE Aruba Networking ClearPass Device Insight?

Highly accurate endpoint classification for environments with many device types, including Internet of Things (IoT)

Simpler troubleshooting of ClearPass solutions across an environment with multiple ClearPass Policy Managers

Visibility into devices’ 802.1X supplicant settings and automated certificate deployment

Agent-based analysis of devices’ security settings and health status, with the ability to implement quarantining

HPE Aruba Networking ClearPass Device Insight is an advanced profiling solution integrated with ClearPass Policy Manager (CPPM) to enhance endpoint classification. It uses a combination of passive and active profiling techniques, along with machine learning, to identify and categorize devices on the network.
Option A, “Highly accurate endpoint classification for environments with many device types, including Internet of Things (IoT),” is correct. ClearPass Device Insight is designed to provide precise device profiling, especially in complex environments with diverse device types, such as IoT devices (e.g., smart cameras, thermostats). It leverages deep packet inspection (DPI), behavioral analysis, and a vast fingerprint database to accurately classify devices, enabling granular policy enforcement based on device type.
Option B, “Simpler troubleshooting of ClearPass solutions across an environment with multiple ClearPass Policy Managers,” is incorrect. ClearPass Device Insight focuses on device profiling, not on troubleshooting ClearPass deployments. Troubleshooting across multiple CPPM instances would involve tools like the Event Viewer or Access Tracker, not Device Insight.
Option C, “Visibility into devices’ 802.1X supplicant settings and automated certificate deployment,” is incorrect. ClearPass Device Insight does not provide visibility into 802.1X supplicant settings or automate certificate deployment. Those functions are handled by ClearPass Onboard (for certificate deployment) or Access Tracker (for authentication details).
Option D, “Agent-based analysis of devices’ security settings and health status, with the ability to implement quarantining,” is incorrect. ClearPass Device Insight does not use agents for analysis; it relies on network traffic and active/passive profiling. Agent-based analysis and health status checks are features of ClearPass OnGuard, not Device Insight. Quarantining can be implemented by CPPM policies, but it’s not a direct benefit of Device Insight.
The ClearPass Device Insight Data Sheet states:
“ClearPass Device Insight provides highly accurate endpoint classification for environments with many device types, including Internet of Things (IoT) devices. It uses a combination of passive and active profiling techniques, deep packet inspection (DPI), and machine learning to identify and categorize devices with precision, enabling organizations to enforce granular access policies in complex networks.” (Page 2, Benefits Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
“ClearPass Device Insight enhances device profiling by offering highly accurate classification, especially for IoT and other non-traditional devices. It leverages a vast fingerprint database and advanced analytics to identify device types, making it ideal for environments with diverse endpoints.” (Page 252, Device Insight Overview Section)
