  1. With OPTION STRICT ON keyword

  2. With OPTION EXPICIT Keyword

  3. With OPTION STRICT OFF keyword

  4. All the above


Correct Option: A
Explanation:

To enable Strict Type Checking in VB.NET, you need to use the "Option Strict On" keyword. This will enforce data type checking for all variables, parameters, and return types in your code.

Option Explicit, on the other hand, enforces explicit declaration of all variables in your code.

Option Strict Off disables strict type checking and allows automatic type conversions, making it easier to write code but potentially less safe.

Therefore, the correct answer is:

The Answer is: A. With OPTION STRICT ON keyword

  1. Add keyword to Method signature

  2. Add [WebMethod] on top of the Method Signature

  3. Add {WebMethod} on top of the Method Signature

  4. None of the Above


Correct Option: A
  1. Using Only Get..EndGet with in property definition

  2. Using Only Set..EndSet with in property definition

  3. Using both Get and Set

  4. None of these


Correct Option: A
  1. AMP bucket number

  2. Primary Index

  3. Primary Key

  4. None of the above


Correct Option: B
  1. Defined immediately after the table CREATE statement, used to find the Primary Key

  2. Defined during the table CREATE statement, used to assign rows to an AMP

  3. Defined immediately after the table CREATE statement, used to assign rows to an AMP

  4. Defined during the table CREATE statement, used to find the Primary Key


Correct Option: B

_____ and _____ are true about the Primary Index

  1. Defined immediately after the table CREATE statement, used to assign rows to an AMP

  2. Defined immediately after the table CREATE statement, used to find the Primary Key

  3. Defined during the table CREATE statement, used to assign rows to an AMP

  4. Defined during the table CREATE statement, used to find the Primary Key


Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of Primary Index in database management systems. Let's go through each option to understand why it is correct or incorrect:

Option A) Defined immediately after the table CREATE statement, used to assign rows to an AMP - This option is incorrect because the Primary Index is not used to assign rows to an AMP. The Primary Index is used to distribute the data across AMPs (Access Module Processors) in a Teradata database.

Option B) Defined immediately after the table CREATE statement, used to find the Primary Key - This option is incorrect because the Primary Index is not used to find the Primary Key. The Primary Key is a constraint that ensures uniqueness of a column or set of columns in a table.

Option C) Defined during the table CREATE statement, used to assign rows to an AMP - This option is correct. The Primary Index is defined during the table CREATE statement and is used to assign rows to an AMP. It determines how the data is distributed across the AMPs for efficient parallel processing.

Option D) Defined during the table CREATE statement, used to find the Primary Key - This option is incorrect because the Primary Index is not used to find the Primary Key.

The correct answer is C) Defined during the table CREATE statement, used to assign rows to an AMP. This option is correct because the Primary Index is defined during the table CREATE statement and is used to assign rows to an AMP.
