Choose all of the statements that are true (10 points).

For you to tướng switch data from a partition to tướng a table or from a table into a partition, the source and target of the ALTER TABLE...SWITCH statement must reside in the same filegroup.

When switching data from a partition to tướng a table or from a table into a partition, the indexes for both bởi not need to tướng be identical

You use the ALTER PARTITION ...SPLIT RANGE T-SQL command in order to tướng drop a partition

Using RANGE LEFT partitions for datetime values is usually best because this approach makes it easier to tướng specify the limits of the ranges

You use the ALTER PARTITION ...MERGE RANGE T-SQL command in order to tướng drop a partition

Any filegroup referenced in the partition scheme must exist before the partition scheme is created.

Compressing the backups of encrypted databases are generally a best practice because they compress more than vãn unencrypted databases

When the database is in Bulk-logged recovery mode, a point in time recovery is not allowed

Point-in-time recovery is not permitted with tệp tin or filegroup backups unless all filegroups are restored to tướng the same point-in-time to tướng maintain database consistency

You should always perform a log tail backup prior to tướng beginning the restore process

Individual tệp tin or filegroup backups can be restored from a full database backup

A tệp tin or filegroup backup is used to tướng backup a portion of the transaction log.

Point-in-time recovery is not permitted with tệp tin or filegroup backups unless all filegroups are restored to tướng the same point-in-time to tướng maintain database consistency

You should always perform a log tail backup prior to tướng beginning the restore process

Individual tệp tin or filegroup backups can be restored from a full database backup

Used to tướng verify that the backup was performed without any corruption

Used to tướng create a second copy of the backup

Used to tướng create a tail log backup prior to tướng beginning restores

Only backup the extents that have changed since the last full backup

Indicates that all backups on the destination truyền thông (i.e. file) should be erased as the new backup is copied on it

Indicates that the backup (even if full) should not reset "changed since last backup" flags in the extents of the database

Can contain both transactional data (logged and recoverable) and non-transactional data where the BLOBs reside on a tệp tin system

Contains transactional data (logged and recoverable) where the BLOBs are stored within the database files

Contains non-transactional data where the BLOBs are stored on a tệp tin system

Contains transactional data (logged and recoverable) where the BLOBs reside on a tệp tin system

SQL Server uses the standard four-part naming convention when referencing database objects. Which of the following is the correct example of the four-part naming? (5 points)

object_name.server_name.schema_name.database_name

server_name.schema_name.database_name.object_name

server_name.database_name.schema_name.object_name

schema_name.object_name.server_name.database_name

server_name.database_name.schema_name.object_name

Which of the following statements are true in SQL Server? (15 points)

Select ALL that apply:

Indexes should be created on columns that have a low cardinality

Page splits cannot occur on HEAP tables during the addition of a row

An ALTER INDEX ... REBUILD on a CLUSTERED index cannot defrag the data pages of the table

Indexes cannot be compressed

A table can have multiple CLUSTERED indexes

Indexes are best added to tướng columns referred to tướng by many queries and that are part of a table with many rows

Filtered indexes require a WHERE clause
