QUESTION NO: 1 Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are tuning the performance of a virtual machines that hosts a Microsoft SQL Server instance. The virtual machine originally had four CPU cores and now has 32 CPU cores. The SQL Server instance uses the default settings and has an OLTP database named db1. The largest table in db1 is a key value store table named table1. Several reports use the PIVOT statement and access more than 100 million rows in table1. You discover that when the reports run, there are PAGELATCH_IO waits on PFS pages 2:1:1, 2:2:1, 2:3:1, and 2:4:1 within the tempdb database. You need to prevent the PAGELATCH_IO waits from occurring. Solution: You add more files to db1. Does this meet the goal? A. Yes B. No Answer: A Explanation: From SQL Server's perspective, you can measure the I/O latency from sys.dm_os_wait_stats. If you consistently see high waiting for PAGELATCH_IO, you can benefit from a faster I/O subsystem for SQL Server. A cause can be poor design of your database - you may wish to split out data located on 'hot pages', which are accessed frequently and which you might identify as the causes of your latch contention. For example, if you have a currency table with a data page containing 100 rows, of which 1 is updated per transaction and you have a transaction rate of 200/sec, you could see page latch queues of 100 or more. If each page latch wait costs just 5ms before clearing, this represents a full half-second delay for each update. In this case, splitting out the currency rows into different tables might prove more performant (if less normalized and logically structured).

QUESTION NO: 2 You upgrade a database named DB1 to Microsoft SQL Server 2016. Users report that performance for several queries is degraded. You determine that the query optimizer is incorrectly estimating the number of rows that the queries will return. You need to resolve the performance issues. How should you complete the Transact-SQL statement? To answer, drag the Transact-SQL segments to the correct locations. Each Transact-SQL segment 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. Answer: Explanation: References: https://docs.microsoft.com/en-us/sql/t-sql/statements/alter-database-scoped-configuration- transact-sql?view=sql-server-2017
QUESTION NO: 3 Your company has many Microsoft SQL Server instances hosted in a data center. You also manage five Microsoft Azure SQL Database instances that are hosted on a single server in Azure. You need to minimize costs associated with Azure resources while maintaining the current performance levels of each Azure SQL Database instance. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order. Answer: Explanation: SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. The databases in an elastic pool are on a single Azure SQL Database server and share a set number of resources at a set price. References: https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-pool
QUESTION NO: 4 You plan to deploy Microsoft SQL Server on a Microsoft Azure Virtual machine. The virtual machine will have a 30-TB database and will have 10 1-TB VHDs for the database. You need to configure the storage to meet the following requirements: Evenly distribute read and write operations across the VHDs. Minimize the read and write time. Which storage configuration should you use? A. a striped volume B. a RAID-5 volume C. a simple storage pool D. a mirrored storage pool E. a parity storage pool Answer: A Explanation: Data that is written to a striped volume is interleaved to all disks at the same time instead of sequentially. Therefore, disk performance is the fastest on a RAID 0 volume as compared to any other type of disk configuration.
QUESTION NO: 5 You have Microsoft SQL Server on a DS-series Microsoft Azure virtual machine. The virtual machine has a production database named DB1. All database files are on drive E and use standard storage. Users report that queries take a long time to execute. You discover that the queries are waiting for pagelatch_IO. You need to reduce the amount of time it takes for the queries to execute. What should you do? A. Move the msdb databases to drive D. B. Move the databases for DB1 to drive D. C. On drive E add more database files for DBI. D. Change drive E to Premium Storage. References: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disks-types Answer: D
