To provide an LACP connection with the maximum available bandwidth, one should configure a link aggregation group (LAG) using all available ports that can be used for data transfer. Since the SFP56 portsare used for stacking, the next best option is to use the 2 SFP28 ports and as many SmartRate 5G (SR5) ports as possible on each switch, which would allow for a 16-member LAG, with 2 SFP28 and 6 SR5 ports on each switch contributing to the LAG.

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.

The RADIUS message that you should look for to ensure a successful connection via 802.1X is Access-Accept. This message indicates that the RADIUS server has authenticated and authorized the supplicant (the device that wants to access the network) and has granted it access to the network resources. The Access-Accept message may also contain additional attributes such as VLAN ID, session timeout, or filter ID that specify how the authenticator (the device that controls access to the network, such as a switch) should treat the supplicant’s traffic.

The other options are not RADIUS messages because:

Authorized: This is not a RADIUS message, but a state that indicates that a port on an authenticator is allowed to pass traffic from a supplicant after successful authentication and authorization.

Success: This is not a RADIUS message, but a status that indicates that an EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). exchange has completed successfully between a supplicant and an authentication server.

Authenticated: This is not a RADIUS message, but a state that indicates that a port on an authenticator has received an EAP-Success message from an authentication server after successful authentication of a supplicant.

The signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover3. To calculate the SNR in dB, we can use the following formula:

SNR (dB) = Signal power (dBm) - Noise power (dBm)

In this question, we are given that the noise floor measures -90 dBm (0.000000001 milliwatts) and the receiver’s signal strength is -65 dBm (0.000316 milliwatts). Therefore, we can plug these values into the formula and get:

SNR (dB) = -65 dBm - (-90 dBm) SNR (dB) = -65 dBm + 90 dBm SNR (dB) = 25 dBm

Therefore, the correct answer is that the SNR is 25 dBm.

A static route is a route that is manually configured on a router or switch and does not change unless it is modified by an administrator. Static routes are used to specify how traffic should reach specific destinations that are not directly connected to the device or that are not reachable by dynamic routing protocols. In Aruba CX switches, static routes can be configured using the ip route command in global configuration mode. Based on the “show ip route” output on an Aruba CX 8400 switch, the route “10.1 20 0/24, vrf default via 10.1.12.2, [1/0]” is a static route because it has an administrative distance of 1 and a metric of 0, which are typical values for static routes.

A frame is the data link layer PDU that encapsulates the network layer PDU (packet) with a header and a trailer that contain information such as source and destination MAC addresses, frame type, error detection, etc. A frame is transmitted over a physical medium such as Ethernet, Wi-Fi, etc.References:https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/1-overview/networking-basics.htm

In large logistic facilities, to ensure comprehensive monitoring and performance analysis, it's recommended to place a User Experience Insight (UXI) sensor in every aisle. This allows for detailed and specific monitoring of network performance across the extensive coverage area of such facilities.
