What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?
A. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic
B. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
C. Tunneling traffic directly to a third-party firewall in a client data center
D. Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
正解：A
解説：
Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.
Reference: Aruba's documentation on UBT and AOS-CX configuration guides detail how to set up user-based tunneling and the benefits of applying advanced security features like DPI to tunneled traffic.

The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?
A. Clear the check box for using simple certificate selection and select the desired certificate manually.
B. Select the desired Trusted Root Certificate Authority and select the check box next to "Don't prompt users."
C. Specify at least two server names under the "Connect to these servers" field.
D. Under the "Connect to these servers" field, use a wildcard in the server name.
正解：C
解説：
To follow best security practices for 802.1X authentication settings in Windows domain clients:
* Specify at least two server names under "Connect to these servers":
* Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
* This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
* Select the desired Trusted Root Certificate Authority and "Don't prompt users":
* Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
* Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.
* Why the other options are incorrect:
* Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
* Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
* Server Validation: Specify the exact RADIUS server names in the "Connect to these servers" field.
* Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
* User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.

A company wants to implement Virtual Network based Tunneling (VNBT) on a particular group of users and assign those users to an overlay network with VNI
3000.
Assume that an AOS-CX switch is already set up to:
. Implement 802.1X to HPE Aruba Networking ClearPass Policy Manager (CPPM)
. Participate in an EVPN VXLAN solution that includes VNI 3000
Which setting should you configure in the users' AOS-CX role to apply VNBT to them when they connect?
A. Gateway zone set to "3000" with no gateway role set
B. Access VLAN ID set to "3000"
C. Gateway zone set to "vni-3000" with no gateway role set
D. Access VLAN set to the VLAN mapped to VNI 3000
正解：D
解説：
To apply Virtual Network based Tunneling (VNBT) to a particular group of users and assign them to an overlay network with VNI 3000, you should configure the users' AOS-CX role to set the Access VLAN to the VLAN mapped to VNI 3000. This ensures that when users connect, their traffic is tunneled through the specified VNI, integrating seamlessly with the EVPN VXLAN solution.
1.Access VLAN Configuration: Setting the Access VLAN to the VLAN mapped to VNI 3000 ensures that users' traffic is directed to the correct virtual network.
2.EVPN VXLAN Integration: This setup allows the AOS-CX switch to participate in the EVPN VXLAN solution, ensuring that user traffic is properly encapsulated and tunneled.
3.Role-Based Assignment: Configuring the role with the correct VLAN mapping ensures that users are dynamically assigned to the appropriate virtual network based on their role.

Refer to the Exhibit:
These packets have been captured from VLAN 10. which supports clients that receive their IP addresses with DHCP.
What can you interpret from the packets that you see here?
These packets have been captured from VLAN 10, which supports clients that receive their IP addresses with DHCP. What can you interpret from the packets that you see here?
A. The mirroring session that captured the packets was likely misconfigured and captured duplicate traffic.
B. Someone is possibly implementing a MAC spoofing attack to gain unauthorized access.
C. Someone is possibly implementing an ARP poisoning and MITM attack.
D. An admin has likely misconfigured two clients to use the same DHCP settings.
正解：B
解説：
The exhibit reveals duplicate IP addresses detected for 10.1.140.6, associated with two different MAC addresses:
* 88:56:56:ab:c6:89
* 88:13:30:a3:02:00
Key observations:
* Duplicate IP Address Detection:
* The message "Duplicate IP address detected for 10.1.140.6" clearly indicates two devices claiming the same IP address.
* This typically occurs when one device spoofs the MAC address of another device to intercept or disrupt traffic.
* MAC Spoofing Context:
* MAC spoofing is a tactic used to impersonate another device's hardware address to gain unauthorized access to a network.
* By spoofing a legitimate IP-MAC pairing, an attacker can bypass security mechanisms or cause denial-of-service conditions.
* Why the Other Options are Incorrect:
* Option B (Mirroring Misconfigured): While mirroring misconfiguration can duplicate traffic, it does not lead to a "duplicate IP detected" alert.
* Option C (Misconfigured DHCP): Misconfigurations usually result in DHCP conflicts, but they do not typically involve two different MAC addresses for the same IP.
* Option D (ARP Poisoning/MITM): ARP poisoning involves falsified ARP tables, but it does not directly trigger duplicate IP address detection. Instead, ARP packets flood the network.
Conclusion:
The evidence strongly suggests MAC spoofing, as two different MAC addresses are claiming the same IP address (10.1.140.6). This behavior is typical of attempts to gain unauthorized access or disrupt network operations.

A company uses HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application option). In the details for a generic device cluster, you see a recommendation for "Windows 8/10" with 70% accuracy.
What does this mean?
A. CPDI has used MAC OUI to group these devices together. The average device's MAC address matches
70% of the "Windows 8/10" OUI.
B. CPDI has matched these devices against several, conflicting system rules. 70% of those rules are for
"Windows 8/10" devices.
C. CPDI has grouped this cluster with similar classified devices. 70% of those classified devices are
"Windows 8/10."
D. CPDI has detected that these devices match about 70% of the system rule for defining "Windows 8/10" devices.
正解：D
解説：
When HPE Aruba Networking ClearPass Device Insight (CPDI) shows a recommendation for "Windows 8
/10" with 70% accuracy for a generic device cluster, it means that CPDI has detected that these devices match about 70% of the system rule criteria for defining "Windows 8/10" devices. This percentage indicates the confidence level based on the observed characteristics and behavior of the devices, helping administrators understand the likelihood that these devices are indeed running Windows 8 or 10.
