The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B. MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.
One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.

Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as "high-efficiency wireless". Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.
Option B: ClientMatch
This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions2.
Therefore, option B is the best technology to implement for your customer's issue.

The Equivalent Isotropic Radiated Power (EIRP) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB2.
The formula for EIRP is:
EIRP=PT-Lc+Ga where PT is the output power of the transmitter in dBm, Lc is the cable and connector loss in dB, and Ga is the antenna gain in dBi.
For AP1, the EIRP can be calculated as:
EIRP=16-4+8=20 dBm
Therefore, the answer B is correct.

The polar plot shows a focused horizontal radiation pattern, indicating the AP emits stronger signal in a specific direction (180°) with weak coverage behind it. This directional focus leads to poor signal in areas not in the main lobe path, such as the opposite side of a hallway.
