In which two ways does a system administrator send web traffic transparently to the Cisco WSA? (Choose two.)

Policy-based routing (PBR) on network infrastructure devices like routers or Layer 3 switches can direct specific web traffic to the WSA without requiring client-side configuration changes, making the redirection transparent.

Referencing a Proxy Auto-Config (PAC) file requires explicit client-side configuration (manual or pushed) to point to the PAC file, which then dictates proxy usage, making it not fully transparent as it involves client-side setup.

Web Cache Communication Protocol (WCCP) allows network devices (like routers) to transparently redirect web traffic to a cache or proxy server like the Cisco WSA, abstracting the proxy configuration from the end-user device.

Configuring the proxy IP address directly in web-browser settings is a manual, explicit client-side configuration, which is not transparent redirection.

Configuring Active Directory Group Policies to push proxy settings still involves client-side configuration (even if automated) and explicit proxy usage, not transparent redirection at the network layer.
