Features: 1) Clustered Instant Access Points Aruba OS version: a) Aruba OS 8 Features: 2) Dynamic Radius Proxy Aruba OS version: a) Aruba OS 8 Features: 3) Scales to more than 10,000 devices Aruba OS version: b) Aruba OS 10 Features: 4) Unifies wired and wireless management Aruba OS version: a) Aruba OS 8 Features: 5) Wireless controllers Aruba OS version: a) Aruba OS 8 ArubaOS is the operating system for all Aruba Mobility Controllers (MCs) and controller-managed wireless access points (APs). ArubaOS 8 delivers unified wired and wireless access, seamless roaming, enterprise grade security, and a highly available network with the required reliability to support high density environments1.
Some of the features of ArubaOS 8 are:
Clustered Instant Access Points: This feature allows multiple Instant APs to form a cluster and share configuration and state information. This enables seamless roaming, load balancing, and fast failover for clients2.
Dynamic Radius Proxy: This feature allows an MC to act as a proxy for RADIUS authentication requests from clients or APs. This simplifies the configuration and management of RADIUS servers and reduces the network traffic between MCs and RADIUS servers3.
Wireless controllers: Aruba wireless controllers are devices that centrally manage and control the wireless network. They provide functions such as AP provisioning, configuration, security, policy enforcement, and network optimization.
ArubaOS 10 is the next-generation operating system that works with Aruba Central, a cloud-based network management platform. ArubaOS 10 delivers greater scalability, security, and AI-powered optimization across large campuses, branches, and remote work environments. Some of the features of ArubaOS 10 are:
Scales to more than 10,000 devices: ArubaOS 10 can support up to 10,000 devices per cluster, which is ten times more than ArubaOS 8. This enables customers to scale their networks without compromising performance or reliability.
Unifies wired and wireless management: ArubaOS 10 provides a single platform for managing both wired and wireless devices across the network. Customers can use Aruba Central to configure, monitor, troubleshoot, and update their devices from anywhere.
Both ArubaOS 8 and ArubaOS 10 share some common features, such as:
Unifies wired and wireless management: Both operating systems provide unified wired and wireless access for customers who use Aruba switches and APs. Customers can use a single interface to manage their entire network infrastructure

Explanation
The Alerts and Events dashboard displays all types of alerts and events generated for events pertaining to device provisioning, configuration, and user management. You can use the Config icon to configure alerts and notifications for different alert categories and severities . You can also view the alerts and events in the List view and Summary view2.

Explanation
The correct statement when comparing 5 GHz and 6 GHz channels with identical channel widths is that 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels.
This statement reflects the fact that higher frequency signals tend to have higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Higher attenuation means that higher frequency signals have shorter range and lower throughput than lower frequency signals. Some facts about this statement are:
5 GHz channels have lower frequency than 6 GHz channels, which means they have lower attenuation than 6 GHz channels.
Lower attenuation means that 5 GHz channels can travel longer distances and provide higher throughputs to clients than 6 GHz channels with identical channel widths.
However, the difference in distance and throughput between 5 GHz and 6 GHz channels may not be significant in indoor environments where there are many obstacles and reflections that affect signal propagation.
The advantage of using 6 GHz channels over 5 GHz channels is that they offer more spectrum availability, less interference, and more non-overlapping channels than 5 GHz channels.
The other options are not correct because:
5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances or provide the same throughputs as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not provide the same throughputs as
6 GHz channels due to higher attenuation of higher frequency signals.

Explanation
EAP-TLS is an authentication method that requires client certificates when authenticating to the network. It provides mutual authentication between the client and the server using public key cryptography and digital certificates.

Explanation
EAP-TEAP is a tunnel-based authentication method that supports both device and user authentication within a single RADIUS session. ClearPass 6.9 supports EAP-TEAP as anauthentication method for Windows 10 clients. References:
