The correct answer is A. True.
Moving the known vulnerabilities list to a high priority for the team to resolve is a proactive and responsible approach taken by the newly hired CISO (Chief Information Security Officer). Even if none of these vulnerabilities have been exploited on the company's network to-date, it is important to address them promptly to mitigate potential risks and prevent future exploitation. By prioritizing the resolution of known vulnerabilities, the CISO is taking proactive measures to enhance the security posture of the company's network and protect it from potential threats.
