Which enterprise caching mode eliminates the need for Layer 4 switches or WCCP enabled routers to intercept user requests?
A.
transparent
B.
proxy
C.
reverse proxy
D.
direct
Explanation:
In proxy mode, end-user web browsers need to be explicitly configured to the IP address or host name of the Content Engine, and there is no need for additional hardware such as Layer 4 switches or Web Cache Communication Protocol (WCCP)-enabled routers to intercept user requests, as in transparent caching. Enterprises are normally interested in deploying transparent network caching, but some enterprises may have a legacy requirement for a proxy (nontransparent) cache.
