Participants in a Tabletop exercise are engaged in scenario discussions to validate and improve response procedures and are not involved in the direct performance of technical response activities like software deployment. 'Deploying intrusion detection systems' and 'Configuring network firewalls' are technical tasks that might be outcome actions from insights gained during a Tabletop, but they are not the focus of these exercises. 'Training security personnel' is broader and not specific to the activity within a Tabletop exercise.
