Complete the sentence by choosing one of the options. With a relational database you can minimize data that is redundant and index the data in order to retrieve data:
Which command can be used with a previously taken fully backup to recover a database?
You company is operating a database that uses three read/write filegroups. The configuration of database allows the use of Full recovery model. The database needs to have a backup strategy and you decide to prepare it. Following are some requirements that are a must: -Storing backups requires disk space.

You have employees working in the Market Analysis department. These users need data from the Customers table and the SalesHistory table. They have to retrieve data by issuing a SELECT statement. They must be prevented from accessing the data in CreditCard or Expiration column of the Customers table. Identify the statement you would use to create the object.

From the options below, can you identify a server scoped securable?
