For an 80m distance between wiring closets, using SFP+ transceivers is appropriate as they can support longer distances than standard copper interfaces. Ports 1/1/51 and 1/1/52 are typically reserved for uplinks on Aruba CX 6200F 48G switches and can support SFP+ transceivers, making them suitable for a redundant link-aggregation port configuration.

For "headless" devices that lack 802.1X support, Multi-Preshared Keys (mPSK) provide a more secure alternative to WPA2-Personal, which uses a single preshared key. mPSK allows for the assignment of unique PSKs to devices or groups of devices, which enhances security by not sharing a single PSK across multiple devices.

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.

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 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.

dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) = 1mW * 10^(-20/10) = 0.01 mW References:https://www.rapidtables.com/convert/power/dBm_to_mW.html

The dBm is a logarithmic unit of power relative to 1 milliwatt (mW). -20 dBm means that the signal strength is 20 decibels lower than 1 mW. In terms of mW, this is 0.01 mW. Each 10 dB decrease represents a tenfold decrease in power. Therefore, -20 dBm is10−210−2or 0.01 mW.

A flashing amber global status indicator LED on an Aruba CX6200M switch typically indicates that the switch has encountered a fault, but it is recoverable. This LED behavior serves as an alert to the network administrator that an issue needs to be addressed, but it does not necessarily mean that the switch is inoperable.

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

A stateful firewall would intelligently deny traffic from a hacker attempting to alter a user's 3-Way Handshake to gain access to their session. Stateful firewalls keep track of the state of active connections and can recognize if an incoming packet is part of an established session. This allows them to detect and block unauthorized access attempts that do not match the known state of a connection.
