Which three ports are used by the vSphere Web Client when connecting directly to an ESXi 6.x host?

443 TCP
902 TCP and UDP
903 TCP
9443 TCP and UDP

The correct answer is: 443 TCP

The vSphere Web Client primarily communicates with an ESXi host over port 443 TCP. This port is designated for HTTPS communications, which is standard for web-based interfaces, ensuring that the data exchanged is done securely. Accessing the ESXi host via the web client allows administrators to perform management tasks in a browser, with the client relying on HTTPS for encrypted communication. The other ports mentioned in the choices serve different functions within the VMware ecosystem. For example, port 902 is used for tasks like VMkernel communications and management agents, while port 903 is often used for console access to a virtual machine's remote console. Port 9443, on the other hand, is utilized in relation to the vSphere Web Client but is not used for direct connection to the ESXi host. It is important for specific services and may be referenced in some management contexts, but the direct interaction through the vSphere Web Client with the ESXi host specifically relies on port 443. Understanding the significance of these ports and their specific roles can help in configuring and troubleshooting VMware environments effectively.
