Exam 70-765 topic 1 question 4 discussion

You have a Microsoft SQL Server 2014 named SRV2014 that has a single tempdb database file. The tempdb database file is eight gigabytes (GB) in size.
You install a SQL Server 2016 instance named SQL Server 2016 by using default settings. The new instance has eight logical processor cores.
You plan to migrate the databases from SRV2014 to SRV2016.
You need to configure the tempdb database on SRV2016. The solution must minimize the number of future tempdb autogrowth events.
What should you do?

Suggested Answer: B 🗳️
In an effort to simplify the tempdb configuration experience, SQL Server 2016 setup has been extended to configure various properties for tempdb for multi- processor environments.
1. A new tab dedicated to tempdb has been added to the Database Engine Configuration step of setup workflow.
2. Configuration options:

Data Files -
✑ Number of files this will default to the lower value of 8 or number of logical cores as detected by setup.
✑ Initial size is specified in MB and applies to each tempdb data file. This makes it easier to configure all files of same size. Total initial size is the cumulative tempdb data file size (Number of files * Initial Size) that will be created.
✑ Autogrowth is specified in MB (fixed growth is preferred as opposed to a non-linear percentage based growth) and applies to each file. The default value of
64MB was chosen to cover one PFS interval.
