Which of the following is categorized as active content blocked by Zscaler?

Active content generally refers to elements on a webpage that can interact with users or perform tasks, often involving scripts or software that run in a user's browser. In this context, adware and spyware are classified as active content because they are designed to execute on a user's system, potentially enabling tracking, collecting data, or displaying unsolicited ads.

Zscaler blocks such active content primarily to protect users from privacy violations and security threats that often accompany adware and spyware. By identifying and mitigating such risks, Zscaler enhances the security posture of organizations and safeguards sensitive information against exploitation.

The other options, while they may present risks, do not fall under the same category of active content in the context of this question. Cookies and web trackers, for example, are used for tracking user behavior without necessarily posing a direct threat as malicious software. Similarly, search engine optimizers are techniques rather than content types and do not interact with the user's system in the same way adware or spyware would. Cloud storage services, while critical for data management, do not inherently possess the characteristics of active content as defined in this context; they facilitate storage and access rather than executing code directly on the user's device.
