Question 1:
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series.
Information and details provided in a question apply only to that question.
You have deployed several GS-series virtual machines (VMs) in Microsoft Azure. You plan to deploy Microsoft SQL Server in a development environment. Each VM has a dedicated disk for backups.
You need to backup a database to the local disk on a VM. The backup must be replicated to another region.
Which storage option should you use?
A. Premium P10 disk storage
B. Premium P20 diskstorage
C. Premium P30 disk storage
D. Standard locally redundant disk storage
E. Standard geo-redundant disk storage
F. Standard zone redundant blob storage
G. Standard locally redundant blob storage
H. Standard geo-redundant blob storage
Correct Answer: E
Note: SQL Database automatically creates a database backups and uses Azure readaccess geo-redundant storage (RA-GRS) to provide geo-redundancy. These backups are created automatically and at no additional charge. You don\’t need to do anything to make them happen. Database backups are an essential part of any business continuity and disaster recovery strategy because they protect your data from accidental corruption or deletion.

Question 2:
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
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.

Question 3:
You administer a Microsoft SQL Server 2014 failover cluster that contains two nodes named Node A and Node B. A single instance of SQL Server is installed on the cluster.
An additional node named Node C has been added to the existing cluster.
You need to ensure that the SQL Server instance can use all nodes of the cluster.
What should you do?
A. Run the New SQL Server stand-alone installation Wizard on Node C.
B. Run the Add Node to SQL Server Failover Cluster Wizard on Node C.
C. Use Node B to install SQL Server on Node C.
D. Use Node A to install SQL Server on Node C.
Correct Answer: B
To add a node to an existing SQL Server failover cluster, you must run SQL Server Setup on the node that is to be added to the SQL Server failover cluster instance. Do not run Setup on the active node.
The Installation Wizard will launch the SQL Server Installation Center. To add a node to an existing failover cluster instance, click Installation in the left-hand pane. Then, select Add node to a SQL Server failover cluster.

Question 4:
You have Microsoft SQL Server on a Microsoft Azure virtual machine. The virtual machine has a database named DB1. DB1 contains a table named Table1 that has 4 billion rows.
Users report that a query using Table1 takes longer than expected to execute.
You review the execution plan for the query and discover that the expected number of returned rows is one, while the actual number of returned rows is 1 million.
You need to reduce the amount of time it takes for the query to execute. The solution must prevent additional performance issues from being introduced.
Hot Area:
Correct Answer:
When you set the AUTO_CREATE_STATISTICS option on, the Query Optimizer creates statistics on individual columns used in a predicate, if these statistics are not already available. These statistics are necessary to generate the query
plan.

Question 5:
You have database that contains a 400-GB table that is read-only.
You need to enable the Stretch Database feature.
How should you complete the statement? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:
Correct Answer:
Section: Deploy and migrate applications
To configure an existing table for Stretch Database, run the ALTER TABLE command.
Here\’s an example that migrates the entire table and begins data migration immediately.
USE ;
GO
ALTER TABLE
