If the BIG-IP device is NOT always located between the client and the server, it will NOT provide full optimization and security.

True. BIG-IP operates as a full proxy, which requires it to be positioned inline in the data path between client and server to terminate and re-originate TCP connections. Without being inline, BIG-IP cannot apply SSL offload, TCP optimization, compression, or security policies because it never sees the actual traffic flow. Features such as application security (ASM/AWAF) and iRules depend entirely on traffic passing through the device.

False is incorrect because BIG-IP's full-proxy architecture fundamentally requires inline placement - there is no out-of-band or tap mode that provides equivalent optimization and security enforcement.
