A new database application is hosted by the instance. The security requirements should be designed for the application. A unique login to the SQL Server 2008 server is assigned to each application user. Stored procedures are included by the application database to execute stored procedures in the MSDB database. SQLAgent jobs are scheduled by the stored procedures in the MSDB database.
Since you are the technical support, you are required to confirm that the stored procedures in the MSDB database should be executed by utilizing the security context of the application user.

Two SQL Server 2008 instances are contained by the site. One is an Enterprise Edition server, and it is on a server that has a redundant array of independent disks (RAID) 10 disk system The other is a Standard Edition server, and it is on a server that has a RAID 5 disk system. A single application is hosted by each instance. A high-availability solution should be recommended for the site to satisfy the business requirements listed below:
First, the solution can be implemented on the current systems.
Secondly, the database is available with least downtime.
Thirdly, Data loss should be cut to the least.
Fourthly, the existing system should be with least impact.
Which solutions should be utilized to finish the task? (Choose more than one)
