Question 1:

What is Angular's two-way data binding?

A) It binds data from the component to the template only.

B) It binds data from the template to the component only.

C) It synchronizes data between the component and the template in both directions.

D) It allows data to flow in one direction, either from the component to the template or vice versa.

Explanation:

Correct Answer: C. Two-way data binding in Angular allows data to synchronize between the component and the template in both directions. Any changes in the component reflect in the template and vice versa.

Question 2:

Which of the following is true about Angular Modules (NgModules)?

A) Angular Modules are not required in Angular applications.

B) An Angular application typically has only one module.

C) Modules help organize an application into cohesive blocks of functionality.

D) Modules can be used to define variables and functions globally.

Explanation:

Correct Answer: C. Angular Modules are essential for organizing an application into cohesive blocks of functionality. They help in managing components, services, and other Angular features within a specific module.

Question 3:

What is the purpose of an Angular service?

A) To define the application's routing configuration.

B) To encapsulate and provide reusability of data, logic, or functionality.

C) To display data in the application's user interface.

D) To define the structure of the application's components.

Explanation:

Correct Answer: B. Angular services are used to encapsulate and provide reusability of data, logic, or functionality across components. They help in sharing common functionality without duplicating code.

Question 4:

Which command is used to generate a new Angular component using the Angular CLI?

A) ng new component

B) ng create component

C) ng generate component

D) ng add component

Explanation:

Correct Answer: C. The Angular CLI command ng generate component is used to create a new Angular component with associated files and configurations.
