What is one of the roles of the network access server (NAS) in the AAA framewonx?
- A. It negotiates with each user's device to determine which EAP method is used for authentication
- B. It enforces access to network services and sends accounting information to the AAA server
- C. It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.
- D. It determines which resources authenticated users are allowed to access and monitors each users session
Answer: B
Explanation:
In the AAA (Authentication, Authorization, and Accounting) framework, the role of the Network Access Server (NAS) is to act as a gateway that enforces access to network services and sends accounting information to the AAA server. The NAS initially requests authentication information from the user and then passes that information to the AAA server. It also enforces the access policies as provided by the AAA server after authentication and provides accounting data to the AAA server based on user activity.

NEW QUESTION # 37 
A company has an Aruba Instant AP cluster. A Windows 10 client is attempting to connect a WLAN that enforces WPA3-Enterprise with authentication to ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client's authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?
- A. whether the client has a valid certificate installed on it to let it support EAP-TLS
- B. whether the client has a third-party 802.1 X supplicant, as Windows 10 does not support EAP-TLS
- C. whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
- D. whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
Answer: A
Explanation:
In the context of WPA3-Enterprise with EAP-TLS authentication, the error message "Client doesn't support configured EAP methods" suggests that the client is not able to complete the EAP-TLS authentication process. EAP-TLS requires that both the server (in this case, CPPM) and the client have a valid certificate for mutual authentication. Windows 10 does support EAP-TLS natively, so options A, C, and D can be ruled out.
The most likely reason for the authentication failure is that the client device does not have the correct client certificate installed, which is required to establish a TLS session with the server. Therefore, ensuring that the client has a valid certificate installed that matches the server's requirements is the correct step to resolve this issue.
NEW QUESTION # 38
A company has a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise security, supported by an Aruba Mobility Controller (MC) and campus APs (CAPs). You have been asked to capture packets from a wireless client connected to this WLAN and submit the packets to the security team.
What is a guideline for this capture?
- A. You should capture the traffic on the MC dataplane to obtain unencrypted traffic.
- B. You should capture the traffic on the AP, so that the capture is as close to the source as possible.
- C. You should use an Air Monitor (AM) to capture the packets in the air.
- D. You should mirror traffic from the switch port that connects to the AP out on a port connected to a packet analyzer.
Answer: C
Explanation:
The correct approach for capturing packets from a wireless client in a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise, managed by an Aruba Mobility Controller and Campus APs, is to use an Air Monitor (AM). An AM is specifically designed to capture wireless traffic "in the air," which means it listens to the wireless signals transmitted between devices and the access points. This method ensures that the capture includes all the necessary details while maintaining the integrity and security of the data as it is transmitted over the air. Using an Air Monitor helps in analyzing the raw wireless traffic before it gets encrypted or tunneled to the Mobility Controller, providing a clear view of the wireless client's activity and interactions. The information regarding the use of Air Monitors for packet capture in such environments can be found in the Aruba Network's official documentation and configuration guides for WLAN setups and security analysis.
NEW QUESTION # 39
The first exhibit shows roles on the MC, listed in alphabetic order. The second and third exhibits show the configuration for a WLAN to which a client connects. Which description of the role assigned to a user under various circumstances is correct?
- A. A user fails 802.1X authentication. The client remains connected, but is assigned the "guest" role.
- B. A user authenticates successfully with 802.1X, and the RADIUS Access-Accept includes an Aruba-User-RoleVSA set to "employeel." The client's role is "employeel."
- C. A user authenticates successfully with 802.1 X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employeel." The client's role is "guest."
- D. A user authenticates successfully with 802.1X. and the RADIUS Access-Accept includes an Aruba-User-Role VSA set to "employee." The client's role is "guest."
Answer: B
Explanation:
In a WLAN setup that uses 802.1X for authentication, the role assigned to a user is determined by the result of the authentication process. When a user successfully authenticates via 802.1X, the RADIUS server may include a Vendor-Specific Attribute (VSA), such as the Aruba-User-Role, in the Access-Accept message.
This attribute specifies the role that should be assigned to the user. If the RADIUS Access-Accept message includes an Aruba-User-Role VSA set to "employee1", the client should be assigned the "employee1" role, as per the VSA, and not the default "guest" role. The "guest" role would typically be a fallback if no other role is specified or if the authentication fails.

NEW QUESTION # 42
A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-CX switches. The company plans to use 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?
- A. TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution.
- B. You will need to mirror traffic to one of CPPM's span ports from a device such as a core routing switch.
- C. ClearPass admins will need to provide the credentials of an API admin account to configure on Aruba devices.
- D. ArubaOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints.
Answer: B
Explanation:
ClearPass Policy Manager (CPPM) uses various methods to classify endpoints, and one of them is TCP fingerprinting, which involves analyzing TCP/IP packets to identify the type of device or operating system sending them. To utilize TCP fingerprinting capabilities, network traffic needs to be accessible to the CPPM.
This can be done by mirroring traffic to CPPM's span port from a device that can see the traffic, like a core routing switch. This approach allows CPPM to observe the TCP characteristics of devices as they communicate over the network, enabling it to make more accurate decisions for device classification.
NEW QUESTION # 43
What is a use case for implementing RadSec instead of RADIUS?
- A. A university wants to protect communications between the students' devices and the network access server.
- B. A school district wants to protect messages sent between RADIUS clients and servers over an untrusted network.
- C. A corporation wants to implement EAP-TLS to authenticate wireless users at their main office.
- D. A organization wants to strengthen the encryption used to protect RADIUS communications without increasing complexity.
Answer: B
Explanation:
RadSec (RADIUS over TLS) is a protocol for transporting RADIUS messages over TLS-encrypted TCP/IP networks. The primary use case for implementing RadSec instead of traditional RADIUS is to protect RADIUS communications, particularly when those messages must travel across an untrusted network, such as the internet. RadSec provides confidentiality, integrity, and authentication for RADIUS traffic between clients and servers which may not be within a single secure network. In the case of a school district that wants to ensure the security of messages sent between RADIUS clients and servers over potentially insecure networks, RadSec would be the appropriate choice.

NEW QUESTION # 45
Device A is contacting https://arubapedia.arubanetworks.com. The web server sends a certificate chain. What does the browser do as part of validating the web server certificate?
- A. It makes sure that the public key in the certificate matches a private key stored on DeviceA.
- B. It makes sure that the key in the certificate matches the key that DeviceA uses for HTTPS.
- C. It makes sure the certificate has a DNS SAN that matches arubapedia.arubanetworks.com
- D. It makes sure that the public key in the certificate matches DeviceA's private HTTPS key.
Answer: C
Explanation:
When a device like Device A contacts a secure website and receives a certificate chain from the server, the browser's primary task is to validate the web server's certificate to ensure it is trustworthy. Part of this validation includes checking that the certificate contains a DNS Subject Alternative Name (SAN) that matches the domain name of the website being accessed-in this case, arubapedia.arubanetworks.com. This ensures that the certificate was indeed issued to the entity operating the domain and helps prevent man-in-the-middle attacks where an invalid certificate could be presented by an attacker. The DNS SAN check is critical because it directly ties the digital certificate to the domain it secures, confirming the authenticity of the website to the user's browser.
NEW QUESTION # 46
What is the purpose of an Enrollment over Secure Transport (EST) server?
- A. It provides a more secure alternative to private CAs at less cost than a public CA.
- B. It helps admins to avoid expired certificates with less management effort.
- C. It acts as an intermediate Certification Authority (CA) that signs end-entity certificates.
- D. It provides a secure central repository for private keys associated with devices' digital certif-icates.
Answer: B
NEW QUESTION # 47
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?
- A. that the snared secret configured for the CPPM authentication server matches the one defined for the device on CPPM
- B. that the MC has valid admin credentials configured on it for logging into the CPPM
- C. that the IP address that the MC is using to reach CPPM matches the one defined for the device on CPPM
- D. that the MC has been added as a domain machine on the Active Directory domain with which CPPM is synchronized
Answer: C
Explanation:
Given the error message from the ClearPass Policy Manager (CPPM) Event Viewer, indicating a RADIUS authentication attempt from an unknown Network Access Device (NAD), you should check that the IP address the Mobility Controller (MC) is using to communicate with CPPM matches the IP address defined for the MC in the CPPM's device inventory. If there is a mismatch in IP addresses, CPPM will not recognize the MC as a known device and will not process the authentication request, leading to the error observed.

NEW QUESTION # 48
What is one practice that can help you to maintain a digital chain or custody In your network?
- A. Enable packet capturing on Instant AP or Moodily Controller (MC) datepath on an ongoing basis
- B. Enable packet capturing on Instant AP or Mobility Controller (MC) control path on an ongoing basis.
- C. Ensure that all network infrastructure devices receive a valid clock using authenticated NTP
- D. Ensure that all network Infrastructure devices use RADIUS rather than TACACS+ to authenticate managers
Answer: C
Explanation:
To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.
References:
Digital forensics and network security protocols that underscore the importance of accurate timekeeping for maintaining a digital chain of custody.
NTP configuration guidelines for network devices, emphasizing the use of authentication to prevent tampering with clock settings.
NEW QUESTION # 49
What is a vulnerability of an unauthenticated Dime-Heliman exchange?
- A. A hacker can replace the public values exchanged by the legitimate peers and launch an MITM attack.
- B. Participants must agree on a passphrase in advance, which can limit the usefulness of Diffie- Hell man in practical contexts.
- C. Diffie-Hellman with elliptic curve values is no longer considered secure in modem networks, based on NIST recommendations.
- D. A brute force attack can relatively quickly derive Diffie-Hellman private values if they are able to obtain public values
Answer: A
Explanation:
The vulnerability of an unauthenticated Diffie-Hellman exchange, particularly when it comes to the risk of a man-in-the-middle (MITM) attack, is a significant concern. In this scenario, a hacker can intercept the public values exchanged between two legitimate parties and substitute them with their own. This allows the attacker to decrypt or manipulate the messages passing between the two original parties without them knowing. This answer is based on the fundamental principles of how Diffie-Hellman key exchange works and its vulnerabilities without authentication mechanisms. Reference materials from cryptographic textbooks and security protocols detail these vulnerabilities, such as those found in standards and publications by organizations like NIST.

Answer: D
NEW QUESTION # 52
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?
- A. Rather than target all clients connected to rogue APs, tarpit containment targets only authorized clients that are connected to a rogue AP, reducing the chance of negative effects on neighbors.
- B. Tarpit containment does not require an RF Protect license to function, while traditional wireless containment does.
- C. Rather than function wirelessly, tarpit containment sends ARP frames over the wired network to poison rogue APs ARP tables and prevent them from transmitting on the wired network.
- D. Tarpit containment forms associations with clients to enable more effective containment with fewer disassociation frames than traditional wireless containment.
Answer: D
Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs.
It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.
