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?

  • A. a Microsoft Azure Stretch Database
  • B. log shipping
  • C. an Always On Availability Group with all replicas in synchronous-commit mode
  • D. a file share witness
  • E. a Microsoft SQL Server failover cluster instance (FCI)
  • F. a Windows cluster with a shared-nothing architecture
  • G. an Always On Availability Group with secondary replicas in asynchronous-commit mode

Suggested Answer: E 🗳️
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 levela 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.

Microsoft SQL Server failover cluster instance (FCI) also syncronizes the SQL Server Agent jobs.
