You have a two-node SQL Server 2014 cluster that has an AlwaysOn availability group configured in synchronous mode.
You plan to provide a reporting solution by using a third node in the cluster.
You need to add the third node. The solution must prevent any impact on the performance of database writes.
You install another server that has SQL Server installed.
Which three additional 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.

Explanation
Step 1: Add a new availability replica in asynchronous mode.
Asynchronous-commit mode minimizes transaction latency on the secondary databases but allows them to lag behind the primary databases, making some data loss possible.
Incorrect: Add a new availability replica in synchronous mode.
Synchronous-commit mode ensures that once a given secondary database is synchronized with the primary database, committed transactions are fully protected. This protection comes at the cost of increased transaction latency.
Step 2: Set Readable Secondary to Read-intent only.
For the secondary role, select a new value from the Readable secondary drop list, as follows: Read-intent only Only read-only connections are allowed to secondary databases of this replica. The secondary database(s) are all available for read access.
Step 3: Configure read-only routing.
Note: Read-only routing refers to the ability of SQL Server to route qualifying read-only connection requests to an available Always On readable secondary replica (that is, a replica that is configured to allow read-only workloads when running under the secondary role). To support read-only routing, the availability group must possess an availability group listener. Read-only clients must direct their connection requests to this listener, and the client's connection strings must specify the application intent as "read-only." That is, they must be read-intent connection requests.

You administer a Microsoft SQL Server database.
Users report that an application that accesses the database displays an error, but the error does not provide meaningful information. No entries are found in the SQL Server log or Windows event logs related to the error.
You need to identify the root cause of the issue by retrieving the error message.

You administer a Microsoft SQL Server 2012 database instance.
The instance is running on a server with the following configuration:
* 1 TB RAM
* SAN storage for database and log files
* 4 quad-core processors
* 64-Bit Windows 2008 R2 operating system
This instance hosts a database with large partitioned tables. Users report that complex queries are taking a long time to complete.
While troubleshooting, you discover that CPU utilization is low (less than 20 percent), disk activity is low (little or no waiting processes), and no significant blocking is occurring.
You need to ensure that the instance can process queries as quickly and efficiently as possible.

Your database contains tables named Products and ProductsPriceLog. The Products table contains columns named ProductCode and Price. The ProductsPriceLog table contains columns named ProductCode, OldPrice, and NewPrice. The ProductsPriceLog table stores the previous price in the OldPrice column and the new price in the NewPrice column.
You need to increase the values in the Price column of all products in the Products table by 5 percent.
You also need to log the changes to the ProductsPriceLog table.
Which Transact-SQL query should you use?
