The correct answer is A. Protocol Profile (Client) with f5-tcp-wan and Protocol Profile (Server) with f5-tcp-lan. To improve network performance for an Internet-facing application using a Standard Virtual Server, the BIG-IP Administrator should configure the client-side TCP profile with f5-tcp-wan and the server-side TCP profile with f5-tcp-lan.

Question

A Standard Virtual Server configured for an application reports poor network performance. This application is accessed mainly from computers on the Internet. What should the BIG-IP Administrator configure on the Virtual Server to achieve better network performance?

Options

  • AProtocol Profile (Client) with f5-tcp-wan and Protocol Profile (Server) with f5-tcp-lan
  • BProtocol Profile (Client) with f5-tcp-lan
  • CProtocol Profile (Client) with fS-tcp-lan and Protocol Profile (Server) with f5-tcp-wan
  • DProtocol Profile (Client) with f5-tcp-optimized

Why each option

To improve network performance for an Internet-facing application using a Standard Virtual Server, the BIG-IP Administrator should configure the client-side TCP profile with f5-tcp-wan and the server-side TCP profile with f5-tcp-lan.

AProtocol Profile (Client) with f5-tcp-wan and Protocol Profile (Server) with f5-tcp-lanCorrect

The f5-tcp-wan profile is specifically designed for optimizing connections over high-latency, potentially lossy wide area networks, which is typical for clients connecting from the Internet. The f5-tcp-lan profile is optimized for high-bandwidth, low-latency local area networks, which is appropriate for connections between the BIG-IP and backend application servers. This combination provides optimal performance by tailoring TCP optimizations to each segment of the connection.

BProtocol Profile (Client) with f5-tcp-lan

Using only f5-tcp-lan on the client-side is unsuitable for Internet-based clients due to the inherent latency and potential packet loss over WAN connections, leading to poor performance.

CProtocol Profile (Client) with fS-tcp-lan and Protocol Profile (Server) with f5-tcp-wan

This option incorrectly applies f5-tcp-lan to the client-side (WAN) and f5-tcp-wan to the server-side (LAN), which would degrade performance on both segments due to mismatched optimizations.

DProtocol Profile (Client) with f5-tcp-optimized

While f5-tcp-optimized exists, it's a general profile; the specific use of f5-tcp-wan and f5-tcp-lan on their respective segments (client/server) provides more tailored and effective optimization for this scenario.
