Explanation:
Fault tolerance allows a system to continue functioning, even with degraded performance, if portions of it fail or degrade, without the entire system or service being taken down. It can detect problems within a service and invoke compensating systems or functions to keep functionality going. Although redundancy is similar to fault tolerance, it is more focused on having additional copies of systems available, either active or passive, that can take up services if one system goes down. Elasticity pertains to the ability of a system to resize to meet demands, but it is not focused on system failures. Automation, and its role in maintaining large systems with minimal intervention, is not directly related to fault tolerance.

Explanation:
While the provider might share any of the other options listed, the provider will not share administration of security controls with the customer. Security controls are the sole province of the provider.

Explanation
Defining the scope of the plan is the very first step in the overall process. Security should be included from the very earliest stages and throughout the entire process. Bringing in security at a later stage can lead to additional costs and time delays to compensate for gaps in planning. Risk assessment, requirements gathering, and analysis are all later steps in the process, and adding in security at any of those points can potentially cause increased costs and time delays.
