Which of the following is a predefined application in cloud firewalls?

The correct answer is Google, as it is a predefined application in cloud firewalls. In the context of cloud firewalls, predefined applications are typically popular services or platforms that are recognized and categorized within the firewall management solutions to ease the management of network traffic.

Google encompasses a wide range of services, including web search, Google Drive, Gmail, and Google Workspace, making it a significant target for businesses employing cloud firewalls. By categorizing Google as a predefined application, organizations can easily set policies for traffic related to Google's services, aiding in the implementation of security measures and user access control.

The other options, while they also represent well-known internet services, may not be listed as predefined applications in a cloud firewall's configuration. This distinction often arises from the frequency of usage and the priority given to certain applications in the context of business needs and security protocols. Therefore, Google stands out in this regard within the framework of cloud-based network security solutions.
