[单选题]30 An LTM Specialist upgrades the switching infrastructure and the backend servers on the LAN segments.
The LTM Specialist notices a 20% memory usage increase on the BIG-IP device while handling the same number of concurrent connections.
A comparison of statistics pre-upgrade and post-upgrade shows a significant reduction on the following:
-RTT between the BIG-IP device and the backend servers
-Packet drops in the switch Time to First Byte (TTFB)
The LTM Specialist is concerned with the scalability of the number of concurrent connections with the new memory usage.
Which setting should be changed to reduce the memory usage on the BIG-IP device?
A.Reduce the proxy buffer high setting on the server-side TCP profile
B.Increase the receive window of the client-side TCP profile
C.Increase the proxy buffer high setting on the server-side TCP profile
D.Reduce the idle of the client-side TCP profile Explanation
After adjusting the architecture, the network quality becomes better. With the connection unchanged the memory usage increase by 20%. It means that the sending speed of the server is higher than the receiving speed of the client. F5 caches more content on the memory and causes the memory usage to....
