You need to deploy a new Microsoft SQL Server environment that meets the following requirements: The SQL Server instance must be highly available. There must be minimal downtime incurred during hardware failure or operating system maintenance. All instance-level security settings and SQL Server Agent jobs must be available without additional synchronization tasks. What should you implement?
Correct Answer: E
Explanation/Reference: Explanation: As part of the SQL Server Always On offering, Always On Failover Cluster Instances leverages Windows Server Failover Clustering (WSFC) functionality to provide local high availability through redundancy at the server-instance level-a failover cluster instance (FCI). An FCI is a single instance of SQL Server that is installed across Windows Server Failover Clustering (WSFC) nodes and, possibly, across multiple subnets. When there is hardware or software failure of a server, the applications or clients connecting to the server will experience downtime. When a SQL Server instance is configured to be an FCI (instead of a standalone instance), the high availability of that SQL Server instance is protected by the presence of redundant nodes in the FCI.
