Which two methods are available in Cisco Secure Web Appliance to process client requests when configured in Transparent mode? (Choose two.)

Transparent mode specifically intercepts traffic without client configuration; explicit HTTP requests are handled when the appliance is configured in Forward (explicit) proxy mode.

PAC (Proxy Auto-Configuration) files are used in explicit proxy deployments to instruct client browsers where to send web traffic, which is not characteristic of transparent mode.

Requiring a proxy for the client web browser describes an explicit proxy setup, where clients are aware of and configured to use the proxy, which is contrary to the nature of transparent mode.

WCCP v2-enabled devices, such as routers or switches, can automatically and transparently redirect HTTP traffic (and optionally HTTPS) destined for common web ports (e.g., port 80) to the Cisco Secure Web Appliance.

Layer 4 switches, using features like policy-based routing or port mirroring, can also transparently intercept and redirect traffic destined to specific ports like port 80 to the Secure Web Appliance without client-side configuration.
