✍️ Sample MOS Questions & Answers
1. What is the primary purpose of a primary key in an Access table?
A primary key uniquely identifies each record in a table, ensuring no two records have the same key value.
2. Which field property in Access allows you to specify a condition that all entered data must satisfy before it can be saved?
A Validation Rule sets a logical condition (e.g., >0 Or Is Null) that data must meet; Access displays the Validation Text message if the rule is violated.
3. In a document, which of the following is used to navigate through the structural view?
Explanation: To navigate through a document's structural view, use the document map. Users can rapidly navigate to different sections by using the overview of the document's headings and subheadings that it gives. Longer texts benefit greatly from this feature because it makes it easier for visitors to find certain content without having to scroll through the entire document.
4. What is the shortcut for redoing the previous action?
Explanation: The shortcut to redo the previous action is "Ctrl + Y". This implies that you can use the keyboard shortcut "Ctrl + Y" to undo an action that you have undone using the "Ctrl + Z" shortcut and return to the original state. This keyboard shortcut is frequently used in a variety of programs and software to rapidly undo and redo tasks without using the mouse or navigating through menus.
5. What type of table relationship exists when one record in Table A can be linked to many records in Table B, but each record in Table B links to only one record in Table A?
A One-to-Many relationship means one record in the primary table (e.g., a customer) can have multiple related records in the foreign table (e.g., orders).
6. Which Access object is specifically designed to automate repetitive tasks by executing a series of predefined actions?
Macros in Access automate tasks by defining a sequence of actions that run when triggered by an event, without requiring VBA programming.
