The following answers are incorrect: plan for implementing workstation locking mechanisms. This is incorrect because locking the workstations have no impact on the LAN or Internet access. plan for protecting the modem pool. This is incorrect because protecting the modem pool has no impact on the LAN or Internet access, it just protects the modem. plan for providing the user with his account usage information.
