70-465 Exam
An Expert interview about 70-465 syllabus
Regarding Microsoft 70-465, all sorts of record examinations are usually computer-based so that the examinees may possibly learn the quiz effects right after test. This assessment middle of the town would probably upload your intraday test out result to the middle machine involving assessment enterprise following the day to day test out done, your assessment enterprise would probably cross your got rid of result to your exam-commission IT enterprise to make the decision calling merit your authentication. Because it is computer-based assessment, and has now instantaneous access for you to effects, the patient can be whole aim inquiries, which often above 80% multiple-choice inquiries, many other concern sorts similar to hauling, (namely to download the solution elected towards a selected spot), fill-in greeting card blanks(primarily are pretty straight forward commands, just like Ciscos IOS demand) , simulator involving businesses(such as, MMC working program concerning IIS looks and present a few demands to your realistic businesses), and a few situation scientific tests(namely make a extensive introduction sentences of your situation, and above five solutions using the situation). )

What should you recommend?
A. partitioned views
B. a database snapshot
C. change data capture
D. table partitioning
Answer: D
Q5. You need to recommend a solution that addresses the concurrency requirement.
What should you recommend?
A. Call the stored procedures in a Distributed Transaction Coordinator (DTC) transaction.
B. Modify the stored procedures to update tables in the same order for all of the stored procedures.
C. Make calls to Sales.Proc1 and Sales.Proc2 synchronously.
D. Break each stored procedure into two separate procedures, one that changes Sales.Table1 and one that changes Sales.Table2.
Answer: B

Topic 3, A. Datum Case A
General Overview
A. Datum 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 a 5-ms latency.
A. Datum standardizes its database platform by using SQL Server 2012 Standard 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 used mainly for reports. The database is recreated every day. A full backup of the database currently takes three hours to complete.
Stored Procedures
A stored procedure named sp1 generates millions of rows of data for multiple reports. Sp1 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 a table in the Products database and searches for information in Table1 based on input from the Products table. After the process is complete, Table1 is deleted.
A stored procedure named sp2 is used to generate a product list. Sp2 takes several minutes to run due to locks on the tables the procedure accesses.
A stored procedure named sp3 is used to update prices. Sp3 is composed of several UPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statements fails, the stored procedure continues to execute.
A stored procedure named sp4 calls stored procedures in the Sales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales, Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause.
A stored procedure named sp5 changes data in multiple databases. Security checks are performed each time sp5 accesses a database.
You suspect that the security checks are slowing down the performance of sp5.
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 Point Objective (RPO) of one hour.
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 view the server state of the SQL Server instance that hosts the Sales database. The junior database administrators will not have any other administrative rights.
