Which two authentication protocols are supported by the Cisco WSA? (Choose two.)

WCCP (Web Cache Communication Protocol) is used for redirecting traffic to web caches or security appliances, not for user authentication.

Cisco WSA supports NTLM (NT LAN Manager) for authentication, which is commonly used to authenticate users against a Microsoft Active Directory domain, leveraging existing Windows domain credentials.

TLS (Transport Layer Security) is a cryptographic protocol for secure communication, primarily for encrypting data in transit, not a user authentication protocol itself.

SSL (Secure Sockets Layer) is the predecessor to TLS and serves the same purpose of encrypting network traffic, but it is not an authentication protocol for users in this context.

The Cisco WSA integrates with LDAP (Lightweight Directory Access Protocol) servers, such as Microsoft Active Directory, to authenticate users and retrieve group membership information for policy enforcement.
