The recommended set of commands to prevent the use of a hub in the access layer is:

switch(config-if)#switchport mode access
switch(config-if)#switchport port-security maximum 1
switch(config-if)#switchport port-security mac-address sticky

Here's the step-by-step explanation:

1. switch(config-if)#switchport mode access: This command is used to set the switch port to access mode. In access mode, the port can only be a member of a single VLAN.

2. switch(config-if)#switchport port-security maximum 1: This command is used to set the maximum number of secure MAC addresses for the interface. Setting this to 1 means that only a single device (with a single MAC address) can connect to the port.

3. switch(config-if)#switchport port-security mac-address sticky: This command is used to enable sticky learning on the interface. Sticky learning means that the switch will dynamically learn the MAC address of the device connected to the port and add it to the running configuration. If the device is disconnected, the switch will still remember the MAC address.

This set of commands effectively prevents a hub from being used because a hub would allow multiple devices (and therefore multiple MAC addresses) to connect to the port, which is not allowed by the port security settings.
