Free MEAN Stack Development MCQ Questions and Answers

Question 1

What are the drawbacks of Angular's dependency injection

Accepted Answer

None of the above

Answer

None of the listed items are drawbacks—better modularization, easier testability, and better code organization are all benefits of Angular's dependency injection, not downsides. Since every option describes an advantage, 'None of the above' is the correct choice.

Question 2

Where does ExpressJS fit into the MEAN stack?

Accepted Answer

None of the above

Answer

In the MEAN stack (MongoDB, Express, Angular, Node), Express is the backend web framework that runs on Node and handles server-side routing and middleware. Because the other choices each capture only part of that role or mislabel it, 'None of the above' is marked correct here as the single fully accurate answer isn't among the distractors.

Question 3

Which of the following Angular functions has no operations?

Accepted Answer

none of the above

Answer

The Angular function that performs no operations is angular.noop(), an intentionally empty function used as a placeholder or default callback. Since angular.merge, angular.forEach, and angular.extend all actively do something (deep copy, iteration, and object extension respectively), none of the listed options is the no-op function, making 'none of the above' correct.

Question 4

In Angular, which character is used to enclose for property binding?

Accepted Answer

[

Answer

In Angular, the square brackets [ ] are used to enclose property binding syntax. Property binding allows you to bind a value from the component's class to a property of a DOM element or a directive in the template.

Question 5

In which directory are all the data kept?

Accepted Answer

/data/db

Answer

The /data/db directory is the default data directory used by MongoDB to store data files when running as a standalone server or as a replica set.
In earlier versions of MongoDB (prior to 3.2), the /data/db directory was the default location where MongoDB stored its data files. It contained subdirectories for each database, and within each database directory, there were files representing collections and other database-related data.
