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.

  • Transact-SQL is central to using SQL Server. All applications that communicate with an instance of SQL Server do so by sending Transact-SQL statements to the server, regardless of the user interface of the application.
  • SQL Server built-in functions are either deterministic or nondeterministic. Functions are deterministic when they always return the same result any time they are called by using a specific set of input values. Functions are nondeterministic when they could return different results every time they are called, even with the same specific set of input values.
  • The account used to install SQL Server should have Full Control share and NTFS permissions on the SMB share folders. The SQL Server service account and SQL Server agent service account should also have Full Control share permissions on the SMB share folders.
  • Shared memory and VIA are not supported on failover clusters. Guest failover clustering is supported in SQL Server 2012. SQL Server failover cluster installation supports Local Disk only for installing the tempdb files. Make sure the path specified for the tempdb data and log files is valid on all cluster nodes. During a failover, if the tempdb directories are not available on the failover target node, the SQL Server resource will fail to come online.
  • SQL Server editions that are supported on Windows Server 2008 R2 64-bit x64 Standard edition are also supported on Windows Small Business Server 64-bit x64.
  • If you change the account that runs SQL Server, first decrypt the files under the old account and then re-encrypt them under the new account.
  • During the setup of SQL Server Express, a login is added for the BUILTIN\Users group. This will allow all authenticated users of the computer to access the instance of SQL Server Express as a member of the public role. You can safely remove this group to restrict Database Engine access to computer users who have individual logins or are members of other Windows groups with logins.
