Why might you use a Subscription in an Angular application?
- To create Observables
- To define component behavior
- To make HTTP requests
- To manage memory leaks
You would use a Subscription in an Angular application to manage memory leaks by unsubscribing from Observables when they are no longer needed. This helps prevent memory consumption issues.
When you want to preload data for a route, you can use the _____ property in the route configuration.

Angular Universal uses a technique known as _____ to handle asynchronous tasks on the server side.
- Client-Side Rendering
- Server-Side Rendering
- Service Workers
- Universal Injection
Angular Universal employs a technique known as Server-Side Rendering (SSR) to handle asynchronous tasks on the server side.
How does the merge operator behave when combining multiple Observables?
- It combines the latest values from all Observables.
- It emits values from all Observables as they arrive.
- It emits values from the first Observable only.
- It waits for all Observables to complete before emitting values.
The merge operator in RxJS emits values from all Observables as they arrive, without waiting for them to complete.
To create an Observable that immediately completes without emitting any values, you can use the _____ function.
- create
- empty
- interval
- of
To create an Observable that immediately completes without emitting any values, you can use the empty function.
When debugging a failing Protractor test, what tool can you use to pause the test execution and inspect the browser's state?
- Browser developer console
- Node.js debugger (e.g., DevTools)
- Protractor's built-in debugger
- WebDriver's built-in debugger (WDB)
When debugging a failing Protractor test, you can use the Node.js debugger, such as Chrome DevTools, to pause the test execution and inspect the browser's state.
