The correct answer is A. Java applications B. Secure protocols C. ActiveX controls D. JavaScript E. Plugins. Anonymizers cannot fully protect user privacy when technologies like Java, ActiveX, JavaScript, plugins, or secure protocols are in use, because these can either bypass the anonymizer or independently reveal identifying information.
Question
Anonymizers are the services that help make a user's own Web surfing anonymous. An anonymizer removes all the identifying information from a user's computer while the user surfs the Internet. It ensures the privacy of the user in this manner. After the user anonymizes a Web access with an anonymizer prefix, every subsequent link selected is also automatically accessed anonymously. Which of the following are limitations of anonymizers? Each correct answer represents a complete solution. Choose all that apply.
Options
- AJava applications
- BSecure protocols
- CActiveX controls
- DJavaScript
- EPlugins

Why each option
Anonymizers cannot fully protect user privacy when technologies like Java, ActiveX, JavaScript, plugins, or secure protocols are in use, because these can either bypass the anonymizer or independently reveal identifying information.
Java applications can make direct network connections outside the anonymizer proxy, leaking the user's real IP address and identity.
Secure protocols (such as HTTPS with client certificates) may transmit identifying credentials or establish direct encrypted tunnels that the anonymizer cannot inspect or strip.
ActiveX controls can execute code at the OS level and make direct network calls that bypass the anonymizer entirely, exposing the user's real identity.
JavaScript can retrieve and transmit client-side information such as browser fingerprints, timezone, and screen resolution directly to servers, circumventing anonymizer protections.
Browser plugins (Flash, Java applets, etc.) operate outside normal HTTP request flows and can establish independent connections that are not routed through the anonymizer.
