What is the main advantage of using Angular Universal for server-side rendering?

  • Enhanced development experience
  • Improved SEO and faster initial page loads
  • Native mobile app support
  • Simplified component creation
The main advantage of using Angular Universal for server-side rendering is improved SEO and faster initial page loads. It allows search engines to index your content better and speeds up the first page load.

To simulate different device capabilities during E2E testing with Protractor, you can configure the _____ in the Protractor configuration file.

  • browser.forkNewDriverInstance
  • capabilities
  • deviceCapabilities
  • protractor.conf.js
To simulate different device capabilities during E2E testing with Protractor, you can configure the capabilities in the Protractor configuration file.

In your Angular application, a certain feature is only available to users who are logged in. You want to write an E2E test to ensure this feature is hidden from guests and visible to authenticated users. How can you simulate different user states in your Protractor tests?

  • Add delays between steps
  • Mock authentication requests
  • Use browser cookies
  • Use random user agents
To simulate different user states in Protractor tests, you should mock authentication requests to authenticate users. This allows you to test features that are accessible to authenticated users and hide them from guests. Using browser cookies, delays between steps, or random user agents are not effective methods for simulating user authentication states.

How do you isolate and test a single component without affecting the actual application in Angular?

  • By using a TestBed
  • By using a browser's developer console
  • By using an End-to-End test
  • By using an Integration test
You can isolate and test a single component without affecting the actual application in Angular by using a TestBed, which provides a testing module environment for the component.

How can you ensure that a user is redirected to a login page when attempting to access a protected child route without proper authentication?

  • Use 'canActivate' Route Guard and return 'false' on unauthorized
  • Use 'canActivateChild' Route Guard and return 'false' on unauthorized
  • Use 'canDeactivate' Route Guard and return 'false' on unauthorized
  • Use 'canLoad' Route Guard and return 'false' on unauthorized
To ensure users are redirected to a login page when accessing a protected child route without proper authentication, you use 'canActivate' and return 'false.'

You are working on a project where the client has specific linting rules. How can you modify the existing linting rules of an Angular CLI project?

  • Modify the .angular-cli.json file
  • Modify the .eslintrc.json file
  • Modify the package.json file
  • Modify the tslint.json file
To modify the linting rules of an Angular CLI project, you should edit the .eslintrc.json file. This file contains the configuration for ESLint, allowing you to customize linting rules to meet the client's specific requirements.

What is the purpose of the compileComponents method in Angular testing?

  • It compiles Angular components for Ahead-of-Time (AOT) compilation.
  • It compiles CSS stylesheets for production use.
  • It compiles TypeScript code for runtime execution.
  • It compiles templates for Just-in-Time (JIT) compilation.
The compileComponents method in Angular testing is used to compile components and their associated templates. This is particularly useful for Ahead-of-Time (AOT) compilation, as it ensures that templates are correctly compiled and ready for testing. It helps catch template-related errors early in the development process.

You have a registration form where users must enter their password twice to confirm it. How would you ensure both password fields match?

  • Use a JavaScript function to compare the two password fields when the form is submitted.
  • Utilize Angular's built-in password validation feature.
  • Implement server-side validation to compare the password fields.
  • Apply a CSS style to visually indicate password match or mismatch.
To ensure both password fields match, it's essential to implement server-side validation. Client-side validation (Option 1) can be bypassed, and Angular's built-in features (Option 2) may not provide the necessary security. A CSS style (Option 4) can enhance user experience but doesn't enforce the match. Server-side validation is the most reliable method.

In a scenario where you need to load some configuration data before determining if a route can be activated, which guard would be the most appropriate to use?

  • CanActivate
  • CanActivateChild
  • CanLoad
  • Resolve
In this scenario, the Resolve guard is the most appropriate. It allows you to fetch data or perform operations before activating a route. This can be useful for loading configuration data asynchronously before the route activation is determined.
