to subscribers?

B.
One-Arm
C.
Routed
D.
Inline
E.
Asymmetric Server Normalization
Answer: E
Cisco ACE working as loadbalancer helps to decide which server should serve a client request. The job of the load balancer is to select the server that can successfully fulfill the client request and do so in the shortest amount of time without overloading either the server or the server farm as a whole.
Asymmetric Server Normalization (ASN) allows the ACE to load balance an initial request from the client to a real server; however, the server directly responds to the client bypassing the ACE. This behavior allows the acceleration of server to client communications and is transparent to the client. When the ACE operates in ASN, it does not perform any network translation when receiving packets destined to the VIP address. Traffic from the client hits the VIP address and the ACE uses the address as the destination address but rewrites the destination MAC address to the address of the real server.
