Trouble Spots

As with any exam, it will vary from person to person as to what is deemed to be difficult. Be sure you are familiar with each of the topics in the exam objectives listed below.

  • The only reliable way to protect your SQL data is to make sure you have a good backup procedure that has been tested. Backups protect you from media failure, user error, hardware failure and natural disasters. It is important that you place your database and backups on separate devices. This may seem obvious, but it happens more often than you think. The SQL Server on-disk storage format is the same in the 64-bit and 32-bit environments. Therefore, backup and restore work across 32-bit and 64-bit environments. A backup created on a server instance running in one environment can be restored on a server instance that runs in the other environment. For partial or copy-only backups, you must use the Transact-SQL BACKUP statement with the PARTIAL or COPY_ONLY option.
  • Microsoft SQL 2012 supports High Availability (HA) using the AlwaysOn feature. AlwaysOn uses an availability group concept to achieve clustered HA services without shared storage.
  • Database mirroring will be removed in a future version of Microsoft SQL Server. It is advised that you using this feature in new development work, and plan to modify applications that currently use this feature. The alternative to database mirroring is the new Use AlwaysOn Availability.
