QUESTION NO: 1
You administer all the deployments of Microsoft SQL Server 2014 in your company. You have two servers in the same data center that hosts your production database.
You need to ensure that the database remains available if a catastrophic server failure or a disk failure occurs.
You also need to maintain transactional consistency of the data across both servers.
You need to achieve these goals without manual intervention.

You use a Microsoft Azure SQL database as a data warehouse. The database is in the Standard service tier and has 400 elastic database throughput units (eDTUs).
You load data to the database by using Azure Data Factory.
You need to reduce the amount of time it takes to load the data.
Solution: You move the database to a Standard database pool that has 800 eDTUs.

You need to maximize performance of writes to each database without requiring changes to existing database tables.
In the table below, identify the database setting that you must configure for each database.
NOTE: Make only one selection in each column. Each correct selection is worth one point.

Correct Answer:
Explanation:
DB1: DELAYED_DURABILITY=FORCED
From scenario: Thousands of records are inserted into DB1 or updated each second. Inserts are made by many different external applications that your company's developers do not control. You observe that transaction log write latency is a bottleneck in performance. Because of the transient nature of all the data in this database, the business can tolerate some data loss in the event of a server shutdown.
With the DELAYED_DURABILITY=FORCED setting, every transaction that commits on the database is delayed durable.
With the DELAYED_DURABILITY= ALLOWED setting, each transaction's durability is determined at the transaction level.
Note: Delayed transaction durability reduces both latency and contention within the system because:
* The transaction commit processing does not wait for log IO to finish and return control to the client.
* Concurrent transactions are less likely to contend for log IO; instead, the log buffer can be flushed to disk in larger chunks, reducing contention, and increasing throughput.
DB2: ALLOW_SNAPSHOT_ISOLATION ON and READ_COMMITTED_SNAPSHOT ON
Snapshot isolation enhances concurrency for OLTP applications.
Snapshot isolation must be enabled by setting the ALLOW_SNAPSHOT_ISOLATION ON database option before it is used in transactions.
The following statements activate snapshot isolation and replace the default READ COMMITTED behavior with SNAPSHOT:
ALTER DATABASE MyDatabase
SET ALLOW_SNAPSHOT_ISOLATION ON
ALTER DATABASE MyDatabase
SET READ_COMMITTED_SNAPSHOT ON
Setting the READ_COMMITTED_SNAPSHOT ON option allows access to versioned rows under the default READ COMMITTED isolation level.
From scenario: The DB2 database was migrated from SQLServer 2012 to SQL Server 2016. Thousands of records are updated or inserted per second. You observe that the WRITELOG wait type is the highest aggregated wait type. Most writes must have no tolerance for data loss in the event of a server shutdown. The business has identified certain write queries where data loss is tolerable in the event of a server shutdown.

QUESTION NO: 8
You are building a new Always On Availability Group in Microsoft Azure. The corporate domain controllers (DCs) are attached to a virtual network named ProductionNetwork. The DCs are part of an availability set named ProductionServers1.
You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server. You attach the node to ProductionNetwork.
The servers in the availability group must be directly accessible only by other company VMs in Azure.
You need to configure the second SQL Server VM for the availability group.
How should you configure the VM? To answer, drag the appropriate configuration settings to the correct target locations. Each configuration setting 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.
NOTE: Each correct selection is worth one point.

Explanation:
Box 1: ProductionNetwork
The virtual network is named ProductionNetwork.
Box 2: None /Not Assigned
As the servers in the availability group must be directly accessible only by other company VMs in Azure, there should be no Public IP address.
Box 3: ProductionServer2
You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server.

Explanation:
Data entry: Threat Detection
SQL Threat Detection provides a new layer of security, which enables customers to detect and respond to potential threats as they occur by providing security alerts on anomalous activities. Users receive an alert upon suspicious database activities, potential vulnerabilities, and SQL injection attacks, as well as anomalous database access patterns.
Business intelligence: Dynamic Data Masking
Dynamic data masking limits (DDM) sensitive data exposure by masking it to non-privileged users. It can be used to greatly simplify the design and coding of security in your application.
