How well you prepare for the exam will determine your success. You must prepare for the exam using all resources available to you. Here are some resources that may help you. Remember that knowledge is never finished. There are endless resources available. Let’s take a look at the steps that will get you on the right track.
Step 1: Refer to the Microsoft 70-762 Official guide
Before you embark on any adventure, it is important to have a clear understanding of what you are getting yourself into. Reviewing each exam objective is an important part of your preparation. To get a clear picture, visit theOfficial Website of the Exam. It is the best site to find information about the exam. Once you have read the basics of the exam. Now it’s time for the Official Exam Guide. Make sure to study every aspect of the exam. Your study plan should be based on the exam objectives. These are the exam domains.
Domain 1- Design and implement database objects (25-30%)
This module will help you design and implement a relational data base scheme. Design tables and schemas that are based on business requirements. Use normalization to improve the design of tables, write table create statements, and determine the most efficient data types. Also, design new indexes using provided tables, queries or plans. Make sure to distinguish between included and indexed columns. Use best practices to implement clustered index columns; recommend new indexes that are based on query plans. Next, design and implement views. This will allow you to select data based upon user or business requirements. You can identify the steps required to design an updateable view, partitioned views, and implement indexed views. Implement columnstore indexes. Identify the use cases that support columnstores indexes. Identify the proper usage of clustered or non-clustered columnsstore indexes. Design standard non-clustered indexes to be used with clustered columnstores indexes. Implement columnstore maintenance.
Domain 2- Implement programmability items (20-25%)
This module will assess your knowledge of the concepts required to maintain data integrity using constraints. Define foreign key and table constraints to enforce business rules. Write Transact-SQL statement to add constraints to tables. Identify the results of Data Manipulation Language statements (DML) given existing constraints and tables. Identify proper usage of PRIMARY KEY constraint. Create stored procedures. Also, create stored procedures. Create triggers and user defined functions.
Domain 3- Manage database concurrency (25-30%)
This module will teach you how to implement transactions. Identify DML statements based on transaction behavior. Recognize differences between implicit and explicit transactions and identify their usage. Implement save points within transactions. Determine the role of transactions in high concurrency databases. Manage isolation levels- Identify differences among Read Uncommitted and Read Committed, Repeatable Read and Serializable isolation levels; determine concurrent queries based upon isolation level; identify the resource impact and performance impact of each isolation level. Optimize concurrency behavior and locking behavior – Troubleshoot locking problems, identify lock escalation behaviors and capture deadlock graphs to identify ways to fix deadlocks. Implement native stored procedures and memory-optimized table. Define the use cases for memory optimized tables versus traditional disk base
