Final answer:
As an IT security administrator, you must create a GPO called Workstation Settings, link it to specific OUs, and import the ws_sec.inf security template to apply its settings.
Step-by-step explanation:
Your task in this lab as the IT security administrator is multi-faceted and involves several steps to enhance the security of your network through Group Policy Objects (GPOs). Firstly, you will create a GPO named Workstation Settings in the CorpNet.local domain. Secondly, you'll need to link the GPO to specific organizational units (OUs) within the domain, namely the Marketing > TempMarketing, Sales > TempSales, and Support OUs. Lastly, you are to import the ws_sec.inf template file from C:\Templates to the Workstation Settings GPO, ensuring that the security settings defined within the template are applied to the workstations within those OUs. The fourth task listed (configuring the network settings for the workstations) has been noted as something to ignore in the instructions provided.
