F5-CTS-LTM BIG-IP Local Traffic Manager Practice Question
An administrator wants to optimize the performance of an HTTPS-based application. Which THREE configurations should they consider to reduce load on the backend servers?
⚠ Common exam trap
Candidates often select 'Caching' or 'iRules' as primary performance optimizations, overlooking that OneConnect is specifically designed to reduce TCP handshake overhead on backend servers for HTTP traffic.

Correct answer & explanation
✓
Enable SSL termination on the BIG-IP.
Offloading resource-intensive tasks from the backend servers is a core function of the LTM. SSL offloading, HTTP compression, and connection pooling are key techniques. By performing decryption and compression on the BIG-IP, the backend servers are freed to focus on application logic, significantly improving response times and overall system scalability, while reducing the computational burden on the web server infrastructure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable SSL termination on the BIG-IP.
Why this is correct
SSL termination moves the CPU-intensive task of encrypting and decrypting HTTPS traffic from the backend server to the BIG-IP. Since the BIG-IP is hardware-accelerated for cryptographic operations, this dramatically reduces the load on the web servers and simplifies certificate management across the infrastructure.
- ✗
Configure the default 'Round Robin' load balancing method.
Why it's wrong here
Round Robin is a distribution algorithm that does not influence the performance of the backend servers themselves. While it spreads the load, it does not reduce the computational requirements per request or optimize how the servers handle the incoming traffic load efficiently.
- ✓
Implement HTTP compression on the BIG-IP.
Why this is correct
HTTP compression reduces the size of the data sent over the network, decreasing bandwidth usage and improving delivery speed. By offloading this process to the BIG-IP, the backend servers save CPU cycles that would otherwise be spent compressing content for every single client request.
- ✓
Enable OneConnect on the virtual server.
Why this is correct
OneConnect allows the BIG-IP to reuse existing TCP connections to the backend servers, significantly reducing the overhead of constant connection establishment and teardown. This decreases the number of active sockets required on the web servers, which is crucial for handling high volumes of HTTP traffic.
- ✗
Increase the maximum number of pool members.
Why it's wrong here
Increasing the number of pool members scales the capacity of the application, but it does not inherently reduce the individual load per server or optimize performance. It merely provides more resources to handle the total volume of traffic without addressing the efficiency of the connections themselves.
