Internet Explorer Interview Questions and Answers

Here are 20 commonly asked Internet Explorer interview questions and answers to prepare you for your interview:

1. What do you know about Internet Explorer?

Internet Explorer is a web browser developed by Microsoft. It is included as part of the Microsoft Windows operating system and is the default web browser for Windows computers. Internet Explorer was first released in 1995 and has been through several major updates since then.

2. How does the browser detect whether a website is an intranet or internet site and which security settings are being used?

The browser detects whether a website is an intranet or internet site by looking at the URL. If the URL includes a period, then the browser will assume that it is an internet site. If the URL does not include a period, then the browser will assume that it is an intranet site. The browser will then use the appropriate security settings for each type of site.

3. What’s your opinion on the use of ActiveX controls in IE10?

ActiveX controls can be useful for adding extra functionality to a web page, but they can also be a security risk. IE10 includes a new security feature that allows users to control whether or not ActiveX controls are allowed to run on a page, which can help mitigate some of the risks associated with them.

4. Can you explain how to minimize third-party addons in Internet Explorer?

In order to minimize third-party addons in Internet Explorer, you will need to go to the Tools menu and select Internet Options. From there, you will want to click on the Security tab and then select the Internet icon. Once you have done that, you will want to click on the Custom Level button and then scroll down to the Miscellaneous section. In that section, you will want to find the setting for “Allow script-initiated windows without size or position constraints” and set it to “Disable”. This will prevent third-party addons from being able to open new windows without any size or position constraints, which can help to reduce the amount of popups and other unwanted windows that you may see.

5. How can you fix an issue with corrupted settings in Internet Explorer?

The first step is to try and reset Internet Explorer to its default settings. If that doesn’t work, then you can try and repair Internet Explorer by going to the Control Panel and opening the “Programs and Features” section. From there, you should be able to find Internet Explorer listed as a program and you can select to repair it.

6. What’s the best way to delete cookies in Internet Explorer?

The best way to delete cookies in Internet Explorer is to go to the Tools menu, select Internet Options, and then click on the Delete Cookies button. This will delete all cookies that are currently stored on your computer.

7. Can you name some common issues that occur when using Internet Explorer, and what would be the best ways to resolve them?

Some common issues that can occur when using Internet Explorer include:

– Compatibility issues with web standards
– Lack of support for newer web technologies
– Poor performance
– Security vulnerabilities

The best way to resolve these issues is to use a different web browser, such as Google Chrome or Mozilla Firefox.

8. What are some different methods for increasing page load times in Internet Explorer?

One method for increasing page load times in Internet Explorer is to use the “Preconnect” command. This command allows you to establish a connection with a server before sending any actual data. This can help to reduce latency and improve page load times. Another method for increasing page load times is to use the “Preload” command. This command allows you to load certain resources ahead of time, so that they are available when needed. This can also help to reduce latency and improve page load times.

9. What is the difference between Cross-site scripting and same-origin policy?

Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject malicious code into webpages viewed by other users. Same-origin policy is a security measure that is implemented by web browsers to prevent malicious code from being executed. Same-origin policy restricts how a document or script loaded from one origin can interact with a resource from another origin.

10. What’s your understanding of XSS attacks?

An XSS attack is a type of injection attack where malicious code is injected into a web page. This code is then executed by the web browser, and can be used to steal information or perform other malicious actions.

11. What are some common reasons why Internet Explorer might crash?

Some common reasons why Internet Explorer might crash include:

– Outdated browser: Internet Explorer is notoriously behind the curve when it comes to adopting new web standards, and this can lead to problems when trying to view newer websites.
– Add-ons and extensions: Third-party add-ons and extensions can sometimes cause instability in Internet Explorer.
– Malware: Malicious software can sometimes target Internet Explorer and cause it to crash.
– Corrupt files: Damaged or corrupt system files can sometimes cause Internet Explorer to crash.

12. Do you think it’s possible to disable Internet Explorer addons via Group Policy? If yes, then how?

Yes, it is possible to disable Internet Explorer addons via Group Policy. You can do this by opening the Group Policy Editor, going to Computer Configuration > Administrative Templates > Windows Components > Internet Explorer, and then setting the “Turn off add-ons by default” policy to “Enabled”.

13. What steps should one take if they see “Internet Explorer cannot display the webpage” error message?

The first step is to check the internet connection to make sure that it is active and working properly. If the connection is fine, then the next step is to clear the browser’s cache and cookies. If that does not work, then the next step is to reset the browser settings. If that still does not work, then the last step is to reinstall the browser.

14. Why is there a need for Internet Explorer Enterprise Mode?

Enterprise Mode is a compatibility mode in Internet Explorer that allows businesses to run older web applications that were designed for older versions of IE. This is important because it allows businesses to continue using older applications that may not be compatible with newer versions of IE, while still being able to take advantage of the newer features and security updates in IE.

15. How can you enable TLS 1.0 in Internet Explorer 8?

You can enable TLS 1.0 in Internet Explorer 8 by going to the Tools menu, selecting Internet Options, clicking on the Advanced tab, and then scrolling down to the Security section. There will be a checkbox labeled “Use TLS 1.0.” Checking this box will enable TLS 1.0 in Internet Explorer 8.

16. Can you give me some examples of real world scenarios where Internet Explorer serves as a better option than Firefox or Chrome?

While there are many opinions on the best browser to use, ultimately it comes down to personal preference. However, there are some scenarios where Internet Explorer may be a better option than Firefox or Chrome. For example, if you are using Windows 10 and need to access Microsoft Edge features, then you will need to use Internet Explorer. Additionally, some websites may only be compatible with Internet Explorer, so you may need to use it in order to access those sites.

17. Can you explain what inline caching is in the context of Internet Explorer?

Inline caching is a performance optimization technique used by Internet Explorer to speed up the loading of web pages. When a web page is loaded, Internet Explorer will cache a copy of the page in memory. If the user navigates to a different page and then navigates back to the original page, Internet Explorer will use the cached copy of the page instead of fetching a new copy from the server. This can speed up the loading of the page since the browser does not need to fetch a new copy of the page from the server.

18. How can you diagnose slow performance issues in Internet Explorer 10?

There are a few things you can do to diagnose slow performance issues in Internet Explorer 10. First, you can try opening the browser’s Task Manager to see if there are any processes that are using up a lot of resources. If you see any, you can try ending those processes to see if that helps improve performance.

Another thing you can do is to disable any add-ons or extensions that you have installed in the browser. This can help to improve performance by reducing the amount of processing that the browser has to do.

Finally, you can try resetting Internet Explorer 10 to its default settings. This will disable any customizations that you have made to the browser, but it can also help to improve performance.

19. When do we get “Content was blocked because it was not signed by a valid security certificate” error messages in Internet Explorer? How can it be fixed?

We get “Content was blocked because it was not signed by a valid security certificate” error messages in Internet Explorer when we try to access a website that has an invalid or expired security certificate. This can be fixed by either updating the security certificate or by changing the security settings in Internet Explorer.

20. How do you troubleshoot a slow browsing experience on Internet Explorer 11?

There are a few things that you can do to troubleshoot a slow browsing experience on Internet Explorer 11. First, you can try clearing your cache and cookies. If that doesn’t help, you can try resetting your Internet Explorer settings. Finally, if all else fails, you can try using a different browser.
