A.

802.1X

B.

802.1q

C.

802.3at

D.

802.3af.

The BEST standard for preventing unauthorized connections to a wired network in a large, multipurpose venue where maintaining physical security is difficult is 802.1X.

802.1X is a standard for port-based network access control (PNAC). It provides a mechanism for authenticating devices that are trying to connect to a network port. With 802.1X, devices must authenticate themselves before they are granted access to the network. This authentication is done using credentials, such as usernames and passwords, certificates, or other authentication methods.

802.1X is commonly used in situations where physical security is difficult to maintain, such as in public spaces, hotels, and airports. It is also used in enterprise networks to control access to sensitive resources.

802.1q and 802.3at/af are not relevant to preventing unauthorized connections to a wired network. 802.1q is a standard for VLAN tagging, which is used to separate traffic on a network into different logical groups. 802.3at and 802.3af are standards for Power over Ethernet (PoE), which allows devices to receive power over Ethernet cables.

In conclusion, implementing 802.1X would be the best choice for preventing unauthorized connections to a wired network in a large, multipurpose venue where maintaining physical security is difficult.
