Aruba’s Captive Portal uses Layer 3 authentication, which means that it intercepts the client’s HTTP requests and redirects them to a web page where the client can enter their credentials. The credentials are then verified by a RADIUS server or a local database before granting network access.

Aruba's Captive Portal primarily uses Layer 3 authentication, which operates at the network layer. When a user connects to a network with a Captive Portal, they are redirected to a web page for authentication. This process involves the user entering credentials or accepting terms and conditions through a web interface before gaining full access to the network. The Captive Portal intercepts the user's web traffic at Layer 3, requiring them to authenticate before proceeding, which is why it's considered a form of Layer 3 authentication.

Based on the exhibit showing the logging server configurations, server 172.17.17.43 will receive the smallest quantity of data because it is set to the "Warning" event log level. This means it will only log events that are categorized as warnings or higher severity, which are typically less frequent than lower severity levels such as "Information," "Debug," or "Emergency."

A UXI (User Experience Insight) is a device that simulates user behavior and tests network performance from the user perspective. It can check different applications, such as HTTP, VOIP, or Office 365, and measure metrics such as latency, jitter, packet loss, and throughput.References:https://www.arubanetworks.com/products/networking/user-experience-insight/

A User Experience Insight (UXI) sensor, such as those used in Aruba networks, is designed to mimic client behavior and test the performance of various network services and applications from the user's perspective. It can simulate user activities and measure the quality of experience for different applications, including HTTP, VOIP, and cloud services like Office 365, providing valuable insights into network performance and user experience.

The command that is used to set a default route to 10.4.5.1 on an Aruba CX switch when in-band management using an SVI is being used is ip route 0.0 0 0/0 10.4.5.1 . This command specifies the destination network address (0.0 0 0) and prefix length (/0) and the next-hopaddress (10.4.5.1) for reaching any network that is not directly connected to the switch. The default route applies to the default VRF Virtual Routing and Forwarding. VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. VRFs are typically used to segment network traffic for security, privacy, or administrative purposes. , which is used for in-band management traffic that goes through an SVI Switch Virtual Interface. SVI is a virtual interface on a switch that allows the switch to route packets between different VLANs on the same switch or different switches that are connected by a trunk link. An SVI is associated with a VLAN and has an IP address and subnet mask assigned to it12.

When using an Aruba standalone AP, selecting “Native VLAN” for the Client VLAN Assignment means that the clients will get their IP addresses from the same subnet as the access point’s IP address. This is because the access point acts as a DHCP server for the clients in this mode.References:https://www.arubanetworks.com/techdocs/Instant_86_WebHelp/Content/instant-ug/iap-dhcp/iap-dhcp.htm

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 an authentication method for Windows 10 clients.References:https://www.arubanetworks.com/techdocs/ClearPass/6.9/Guest/Content/CPPM_UserGuide/EAP-TEAP/EAP-TEAP.htm

For the requirement to authorize both device and user credentials within one Radius session, the correct solution would be ClearPass 6.9 with EAP-TEAP (EAP-Tunneled Extensible Authentication Protocol). EAP-TEAP is a tunneling protocol that creates a secure communication channel between the client and the server, allowing for the transmission of multiple authentication transactions within a single session. This capability is particularly useful in scenarios where both user and device credentials need to be verified before granting access to network resources, providing an additional layer of security and ensuring that both the user and the device are authorized to access the network.

In Aruba Central's network check page, you can run several diagnostic tests on switches. A ping test is a common utility to check the reachability of a host on an IP network. A Power over Ethernet (PoE) check can help verify the power delivery status to PoE-capable devices. These tests are crucial for ensuring connectivity and power supply to network devices

In a 2.4GHz WLAN environment, channels 1, 6, and 11 are recommended for use simultaneously to avoid co-channel interference because these channels do not overlap with each other. Each of these channels is separated by enough frequency space to ensure that the signals do not interfere, which is not the case with other channel combinations.

The administrative distance is used as a trust rating for route entries (B). It is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. The lower the administrative distance value, the more trustworthy the source of the route. For example, a directly connected network has an administrative distance of 0 because it is the most trusted source of routing information. In contrast, routes learned from different routing protocols have higher administrative distances, reflecting their relative trustworthiness.

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 severities1. You can also view the alerts and events in the List view and Summary view2.
