B. Synchronize its clock with an NTP server that requires authentication.
C. Use RADIUS for enforcing 802.1X authentication to ClearPass.
D. Obtain downloadable user roles (DURs) from ClearPass.

Answer: A

Explanation:
A Server Certificate is required by Aruba Mobility Controller when using RadSec to secure RADIUS communication. RadSec provides a secure transport for RADIUS traffic through SSL/TLS which requires the use of a Server Certificate to establish the secure tunnel. In the other scenarios listed, a Server Certificate is not explicitly required for the operations mentioned.

NEW QUESTION # 146
Refer to the exhibit.

You need to ensure that only management stations in subnet 192.168.1.0/24 can access the ArubaOS-Switches' CLI. Web Ul. and REST interfaces The company also wants to let managers use these stations to access other parts of the network What should you do?

A. Specify 192.168.1.0.255.255.255.0 as authorized IP manager address
B. Configure the switch to listen for these protocols on OOBM only.
C. Establish a Control Plane Policing class that selects traffic from 192.168 1.0/24.
D. Specify vlan 100 as the management vlan for the switches.

Answer: A

Explanation:
To ensure that only management stations in the subnet 192.168.1.0/24 can access the ArubaOS-Switches' Command Line Interface (CLI), Web UI, and REST interfaces, while also allowing managers to access other parts of the network, you should specify 192.168.1.0 255.255.255.0 as the authorized manager IP address on the switches. This configuration will restrict access to the switch management interfaces to devices within the specified IP address range, effectively creating a management access list.

NEW QUESTION # 147
Refer to the exhibit, which shows the settings on the company's MCs.
You have deployed about 100 new HPE Aruba Networking 335 APs. What is required for the APs to become managed?

A. Approving the APs as authorized APs on the AP whitelist
B. Configuring a PAPI key that matches on the APs and MCs
C. Installing CA-signed certificates on the APs
D. Installing self-signed certificates on the APs

Answer: A

Explanation:
The scenario involves an AOS-8 Mobility Controller (MC) with Control Plane Security (CPSec) enabled and auto certificate provisioning disabled. CPSec is a feature that secures the control plane communication between the MC and APs using certificates. When CPSec is enabled, APs must be authorized and trusted by the MC to become managed.
CPSec Enabled, Auto Cert Provisioning Disabled: When CPSec is enabled, APs must have a valid certificate to establish a secure control plane connection with the MC. If auto certificate provisioning is disabled (as shown in the exhibit), the MC does not automatically provision certificates to the APs. Instead, the APs must already have a factory-installed certificate (or a manually installed certificate), and the MC must trust the AP's certificate by having the issuing CA in its trust list. Additionally, the AP must be on the MC's AP whitelist to be authorized.
AP Whitelist: The AP whitelist is a list of authorized APs maintained on the MC (or Mobility Master, MM, if present). For an AP to become managed, its MAC address must be in the whitelist, especially when CPSec is enabled and auto provisioning is disabled. This ensures that only authorized APs can connect to the MC.
Option A, "Installing CA-signed certificates on the APs," is incorrect because HPE Aruba Networking APs, such as the 335 series, come with factory-installed certificates signed by Aruba's CA. These certificates are sufficient for CPSec, provided the MC trusts the Aruba CA (which is typically preconfigured). Manually installing CA-signed certificates is not required unless the factory certificates are not used or trusted.
Option B, "Approving the APs as authorized APs on the AP whitelist," is correct. With CPSec enabled and auto cert provisioning disabled, the APs must be explicitly authorized by adding their MAC addresses to the AP whitelist on the MC. This step ensures that the MC accepts the AP's certificate and allows it to become managed.
Option C, "Installing self-signed certificates on the APs," is incorrect because self-signed certificates are not typically used for CPSec. APs use factory-installed certificates, and the MC must trust the issuing CA. Self-signed certificates would require manual trust configuration on the MC, which is not a standard practice.
Option D, "Configuring a PAPI key that matches on the APs and MCs," is incorrect. PAPI (Protocol for AP Provisioning and Information) keys are used for securing communication between APs and the MC in non-CPSec environments or for specific configurations (e.g., when CPSec is disabled). When CPSec is enabled, certificate-based authentication replaces the need for a PAPI key.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"When Control Plane Security (CPSec) is enabled and auto certificate provisioning is disabled, APs must be authorized by adding their MAC addresses to the AP whitelist on the Mobility Controller (or Mobility Master). The AP uses its factory-installed certificate to establish a secure control plane connection with the MC. The MC must trust the CA that issued the AP's certificate (e.g., Aruba's CA), and the AP must be in the whitelist to become managed. To add an AP to the whitelist, navigate to Configuration > Access Points > AP Whitelist in the MC UI and add the AP's MAC address." (Page 395, CPSec Configuration Section) Additionally, the HPE Aruba Networking CPSec Deployment Guide notes:
"If auto cert provisioning is disabled, the AP whitelist becomes mandatory for CPSec. Each AP must be explicitly approved by adding its MAC address to the whitelist, ensuring that only authorized APs can connect to the MC. The AP's factory certificate is used for authentication, and no manual certificate installation is required on the AP." (Page 12, CPSec with Manual Provisioning Section)

NEW QUESTION # 148
Refer to the exhibit, which shows the current network topology.

You are deploying a new wireless solution with an Aruba Mobility Master (MM). Aruba Mobility Controllers (MCs). and campus APs (CAPs). The solution will Include a WLAN that uses Tunnel for the forwarding mode and Implements WPA3-Enterprise security What is a guideline for setting up the vlan for wireless devices connected to the WLAN?

A. Assign the WLAN to a single new VLAN which is dedicated to wireless users
B. Use wireless user roles to assign the devices to a range of new vlan IDs.
C. Assign the WLAN to a named VLAN which specified 100-150 as the range of IDs.
D. Use wireless user roles to assign the devices to different VLANs in the 100-150 range

Answer: D

Explanation:
When setting up VLANs for a wireless solution with an Aruba Mobility Master (MM), Aruba Mobility Controllers (MCs), and campus APs (CAPs), it is recommended to use wireless user roles to assign devices to different VLANs. This allows for greater flexibility and control over network resources and policies applied to different user groups. Wireless user roles can dynamically assign devices to the appropriate VLAN based on a variety of criteria such as user identity, device type, location, and the resources they need to access. This approach aligns with the ArubaOS features that leverage user roles for network access control, as detailed in Aruba's configuration and administration guides.
