When would you rather replace some or all of a system rather than keep it updated?arrow_forwardA system administrator's responsibility is to keep production software safe from updates. Due to the shortened SDLC of the updated software, rapid enhancements are required. These enhancements need approval before they may be implemented. Production downtime will be minimized thanks to four measures implemented before updates are implemented.arrow_forward
