A consultant is configuring a vulnerability scanner for a large, global organization in multiple countries. The consultant will be using a service account to scan systems with administrative privileges on a weekly basis, but there is a concern that hackers could gain access to the account and pivot throughout the global network.
Which of the following would be BEST to help mitigate this concern?


A. Create different accounts for each region, each configured with push MFA notifications.
B. Create one global administrator account and enforce Kerberos authentication.
C. Create different accounts for each region, limit their logon times, and alert on risky logins.
D. Create a guest account for each region, remember the last ten passwords, and block password reuse.
