Which three options are attack vectors protected by Web Security? (Choose three.)

Endpoints are a primary protected vector because web security gateways inspect and control HTTP/HTTPS traffic originating from desktop and laptop endpoints.

Mobile devices are protected because web security solutions such as Cisco Umbrella extend coverage to mobile users roaming off the corporate network via DNS-layer and proxy enforcement.

Offline devices have no network connectivity and therefore generate no web traffic for a web security solution to inspect or protect.

Backups are data storage artifacts, not a network communication vector, and fall outside the scope of web security policy enforcement.

Voicemail is a unified communications vector transmitted over telephony or UC protocols, not HTTP/HTTPS web traffic that web security solutions are designed to handle.

Web traffic itself is the foundational vector that web security solutions are built to defend, inspecting URLs, content, and file downloads to block malware and phishing.
