The correct answer is A. Reduce the proxy buffer high setting on the server-side TCP profile. 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…
Question
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?
Options
- AReduce the proxy buffer high setting on the server-side TCP profile
- BIncrease the receive window of the client-side TCP profile
- CIncrease the proxy buffer high setting on the server-side TCP profile
- DReduce 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....
