When Cheryl is browsing the Web, which protocol is she likely using?

Cheryl is likely using HTTP (Hypertext Transfer Protocol) while browsing the Web because HTTP is the foundational protocol used for transferring web pages and other content over the internet. This protocol enables web browsers to communicate with web servers, facilitating the retrieval of HTML documents that make up websites. It allows for the loading of webpages, images, scripts, and other resources that users interact with during their online browsing experience.

Other protocols mentioned, such as SNMP, FTP, and TFTP, serve different purposes. SNMP is primarily used for network management, FTP is designed for transferring files between computers on a network, and TFTP is a simpler file transfer protocol with limited features compared to FTP. Since Cheryl is engaged in typical web browsing activities, HTTP is the most suitable and relevant protocol for her actions.
