• Question 56:

  Overview

  General Overview

  ADatum Corporation has offices in Miami and Montreal.

  The network contains a single Active Directory forest named adatum.com. The offices connect to each other by using a WAN link that has 5-ms latency. A. Datum standardizes its database platform by using SQL Server 2014 Enterprise

  edition.

  Databases

  Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev.

  Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases.

  The Customers database contains two tables named Customers and Classifications.

  The following graphic shows the relevant portions of the tables:

  

  The following table shows the current data in the Classifications table:

  

  The Inventory database is updated frequently.

  The database is often used for reporting.

  A full backup of the database currently takes three hours to complete.

  Stored Procedures

  A stored procedure named USP_1 generates millions of rows of data for multiple reports. USP_1 combines data from five different tables from the Sales and Customers databases in a table named Table1. After Table1 is created, the

  reporting process reads data from Table1 sequentially several times. After the process is complete, Table1 is deleted. A stored procedure named USP_2 is used to generate a product list. The product list contains the names of products

  grouped by category.

  USP_2 takes several minutes to run due to locks on the tables the procedure accesses. The locks are caused by USP_1 and USP_3.

  A stored procedure named USP_3 is used to update prices. USP_3 is composed of several UPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statements fails, the stored procedure fails. A

  stored procedure named USP_4 calls stored procedures in the Sales, Customers, and Inventory databases.

  The nested stored procedures read tables from the Sales, Customers, and Inventory databases. USP_4 uses an EXECUTE AS clause.

  All nested stored procedures handle errors by using structured exception handling. A stored procedure named USP_5 calls several stored procedures in the same database. Security checks are performed each time USP_5 calls a stored

  procedure.

  You suspect that the security checks are slowing down the performance of USP_5. All stored procedures accessed by user applications call nested stored procedures.

  The nested stored procedures are never called directly.

  Design Requirements

  Data Recovery

  You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Time Objective (RTO) of 5 minutes.

  You must be able to recover data from the Dev database if data is lost accidentally. You have a Recovery Point Objective (RPO) of one day.

  Classification Changes

  You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future. Management requests that historical data be

  maintained for the previous classifications. Security A group of junior database administrators must be able to manage security for the Sales database. The junior database administrators will not have any other administrative rights. A. Datum

  wants to track which users run each stored procedure.

  Storage

  ADatum has limited storage. Whenever possible, all storage space should be minimized for all databases and all backups.

  Error Handling

  There is currently no error handling code in any stored procedure.

  You plan to log errors in called stored procedures and nested stored procedures. Nested stored procedures are never called directly.

  You need to recommend a solution for the planned changes to the customer classifications. What should you recommend? (Each correct answer presents part of the solution. Choose all that apply.)

  A. Add a row to the Customers table each time a classification changes.
  B. Add columns for each classification to the Customers table.
  C. Add a table to track any changes made to the classification of each customer.
  D. Add a column to the Classifications table to track the status of each classification.
  E. Implement change data capture.
  C. Add a table to track any changes made to the classification of each customer.
  D. Add a column to the Classifications table to track the status of each classification.

• Question 57:

  You are implementing log shipping. You configure a secondary server in standby mode. You configure log shipping to occur hourly and keep up to seven days of log backups.

  Users create reports by querying the secondary server. Transaction logs are not applied to the secondary server.

  You need to ensure that the secondary server has current data at the beginning of each business day.

  What are two possible ways to achieve the goal? Each answer represents a complete solution.

  A. Create a snapshot database from a daily backup to use as the secondary database. Revert the snapshot database back to the previous business day.
  B. Disconnect users while transaction logs are applied.
  C. Configure the secondary server as a database mirroring target server.
  D. Allow restore operations to accumulate. Run a Microsoft SQL Agent job that disconnects all users that are connected to the secondary server.
  C. Configure the secondary server as a database mirroring target server.
  D. Allow restore operations to accumulate. Run a Microsoft SQL Agent job that disconnects all users that are connected to the secondary server.

• Question 58:

  DRAG DROP

  You plan to deploy a database to SQL Azure. You are designing two stored procedures named USP_1 and USP_2 that have the following requirements:

  Prevent data read by USP_1 from being modified by other active processes.

  Allow USP_2 to perform dirty reads.

  You need to recommend the isolation level for the stored procedures.

  The solution must maximize concurrency.

  Which isolation levels should you recommend? To answer, drag the appropriate isolation level to the correct stored procedure in the answer area.

  Select and Place:

  

  

  ---

  SP1 – repeatable read; SP2 – read uncommited Note:

  - SP1: repeatable read a repeatable read scan retains locks on every row it touches until the end of the transaction. Even rows that do not qualify for the query result remain locked. These locks ensure that the rows touched by the query cannot be updated or deleted by a concurrent session until the current transaction completes (whether it is committed or rolled back).

  -SP2: read uncommitted permits repeatable reads

• Question 59:

  DRAG DROP

  You have a SQL Azure database named Database1.

  You need to design the schema for a table named table1.

  Table1 will have less than one million rows.

  Table1 will contain the following information for each row:

  

  The solution must minimize the amount of space used to store each row.

  Which data types should you recommend for each column? To answer, drag the appropriate data type to the correct column in the answer area.

  Select and Place:

• Question 60:

  You administer a Microsoft SQL Server 2016 default instance. The instance is hosted by a server that has a local firewall configured.

  What should you do?

  A. Enable inbound connections on TCP port 1434 in the Windows Firewall on the server.
  B. Execute the following Transact-SQL command: sp_configure 'remote admin connections',
  C. Execute the Reconfigure command.
  D. Execute the following Transact-SQL command: sp_configure 'remote access', 1
  E. Restart the SQL Server Agent Service.
  F. Enable inbound connections on TCP port 135 in the Windows Firewall on the server.
  A. Enable inbound connections on TCP port 1434 in the Windows Firewall on the server.
  B. Execute the following Transact-SQL command: sp_configure 'remote admin connections',
  C. Execute the Reconfigure command.
