You administer two instances of Microsoft SQL Server 2012. You deploy an application that uses a database on the named instance. The application is unable to connect to the database on the named instance. You need to ensure that the application can connect to the named instance. What should you do?

• A. Configure the named SQL Server instance to use an account that is a member of the Domain Admins group.
• B. Open port 1433 on the Windows firewall on the server.
• C. Configure the application as data-tiered.
• D. Start the SQL Server Browser Service.

You are a database developer of a Microsoft SQL Server 2012 database. You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the SourceID. A sample of this data is as shown in the following table.

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and then CustomerID. Which Transact- SQL statement should you use?

• A. CREATE TABLE Customer (SourceID int NOT NULL, CustomerID int NOT NULL, CustomerName varchar(255) NOT NULL, CONSTRAINT UQ_Customer UNIQUE CLUSTERED (SourceID, CustomerID));
• B. CREATE TABLE Customer (SourceID int NOT NULL PRIMARY KEY CLUSTERED, CustomerID int NOT NULL UNIQUE, CustomerName varchar(255) NOT NULL);
• C. CREATE TABLE Customer
  (SourceID int NOT NULL PRIMARY KEY CLUSTERED,
  CustomerID int NOT NULL PRIMARY KEY CLUSTERED,
  CustomerName varchar(255) NOT NULL);
• D. CREATE TABLE Customer (SourceID int NOT NULL, CustomerID int NOT NULL PRIMARY KEY CLUSTERED, CustomerName varchar(255) NOT NULL);

You administer a Microsoft SQL Server 2012 instance that has several SQL Server Agent jobs configured.
When SQL Server Agent jobs fail, the error messages returned by the job steps do not provide the required
detail. The following error message is an example error message:
"The job failed. The Job was invoked by User CONTOSO\ServiceAccount. The last step to run was step 1
(Subplan_1)."
You need to ensure that all available details of the job step failures for SQL Server Agent jobs are retained.
What should you do?

• A. Configure event forwarding.
• B. Configure output files.
• C. Disable the Limit size of job history log feature.
• D. Expand agent logging to include information from all events.

You administer a Microsoft SQL Server 2012 database that has multiple tables in the Sales schema. Some users must be prevented from deleting records in any of the tables in the Sales schema. You need to manage users who are prevented from deleting records in the Sales schema. You need to achieve this goal by using the minimum amount of administrative effort. What should you do?

• A. Create a custom database role that includes the users. Deny Delete permissions on the Sales schema for the custom database role.
• B. Deny Delete permissions on each table in the Sales schema for each user.
• C. Create a custom database role that includes the users. Deny Delete permissions on each table in the Sales schema for the custom database role.
• D. Include the Sales schema as an owned schema for the db_denydatawriter role. Add the users to the db_denydatawriter role.

You are a database developer for an application hosted on a Microsoft SQL Server 2012 server. The database contains two tables that have the following definitions:

Global customers place orders from several countries. You need to view the country from which each customer has placed the most orders. Which Transact-SQL query do you use?

• A. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  RANK() OVER (PARTITION BY CustomerID
  ORDER BY COUNT(OrderAmount) DESC) AS Rnk
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  WHERE o.Rnk = 1
• B. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  RANK() OVER (PARTITION BY CustomerID
  ORDER BY OrderAmount DESC) AS Rnk
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  WHERE o.Rnk = 1
• C. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM (SELECT c.CustomerID, c.CustomerName, o.ShippingCountry, RANK() OVER (PARTITION BY CustomerID
  ORDER BY COUNT(o.OrderAmount) ASC) AS Rnk
  FROM Customer c
  INNER JOIN Orders o
  ON c.CustomerID = o.CustomerID
  GROUP BY c.CustomerID, c.CustomerName, o.ShippingCountry) cs
  WHERE Rnk = 1
• D. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  COUNT(OrderAmount) DESC) AS OrderAmount
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  ORDER BY OrderAmount DESC
