You have a SQL Server 2016 database named DB1.
You plan to import a large number of records from a SQL Azure database to DB1.
You need to recommend a solution to minimize the amount of space used in the transaction log during the import operation.
What should you include in the recommendation?
A. The bulk-logged recovery model
B. The full recovery model
C. A new partitioned table
D. A new log file
E. A new file group
Correct Answer: A
Explanation/Reference:
Explanation:
Compared to the full recovery model, which fully logs all transactions, the bulk-logged recovery model minimally logs bulk operations, although fully logging other transactions. The bulk-logged recovery model protects against media failure and, for bulk operations, provides the best performance and least log space usage.
Note: The bulk-logged recovery model is a special-purpose recovery model that should be used only intermittently to improve the performance of certain large-scale bulk operations, such as bulk imports of large amounts of data.
