What command would configure switch ports connecting to hosts as permanent access ports?

Configuring switch ports as permanent access ports is done to ensure that the ports are set to a specific mode that allows end devices (like computers or printers) to connect without any need for additional configuration or negotiation. The command "switchport mode access" explicitly sets the port to operate in access mode, meaning it will only transmit traffic for a single VLAN and will not participate in VLAN tagging that is characteristic of trunk ports.

Using access mode is particularly important for ports connecting directly to hosts because it simplifies management and enhances security by preventing unintended VLAN information from being sent across the link. When a port is set to access mode, it ensures that any device connected to that port will only be in the VLAN configured on that port, leading to predictable network behavior and straightforward traffic management.

In contrast, other commands such as "switchport mode trunk" would configure the port to carry multiple VLANs. The command "switchport access vlan" specifies which VLAN the access port belongs to but does not set the port to access mode by itself. Lastly, "switchport trunk allow" manages VLANs that can pass through a trunk port, which does not apply to access ports. Thus, "switchport mode access" is the correct choice for making a port an access
