   Show answer

   Answer: C

   Explanation

   Answer is C even if the answer is worded terribly. Step 7 (documenting): Documenting isn't about lessons learned, documenting is to document what you actually did to resolve the issue in case something happens again, especially if the problem comes back quickly. Lessons learned is something you do after the fact, saying there was a break in procedure that caused the outage.

   • BA role-based access control policy
   • CFirewalls on the software development servers
   • DLonger and more complex password requirements

   Show answer

   Answer: B

   Explanation

   Role-based access control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within an enterprise. In this context, roles are defined according to job competency, authority, and responsibility within the enterprise. Implementing RBAC will ensure that users only have the access necessary to fulfill their current roles. So, if a user changes roles, their access permissions change accordingly, preventing them from accessing systems or performing actions that are not relevant to their current role.
