F5-CTS-LTM BIG-IP Local Traffic Manager Practice Question
An LTM Specialist needs to ensure that client traffic is distributed evenly across four backend servers, but some servers are more powerful than others. Which load balancing method should be chosen?
⚠ Common exam trap
Candidates frequently choose 'Least Connections' or 'Round Robin' regardless of server capacity, ignoring that 'Ratio' is the specific algorithm designed to handle servers with different hardware performance levels.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ratio
Ratio load balancing is the appropriate method when server capacities differ. By assigning a higher ratio weight to the more powerful servers, the BIG-IP will send a proportionally larger amount of traffic to them. This ensures that the load is balanced relative to the processing power of each backend node, maximizing the performance of the overall application cluster and preventing smaller servers from being overwhelmed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Round Robin
Why it's wrong here
Round Robin distributes traffic equally to all servers in the pool, regardless of their capacity. In a pool with heterogeneous hardware, this will result in the weaker servers becoming bottlenecks while the more powerful servers remain underutilized, leading to suboptimal application performance.
- ✓
Ratio
Why this is correct
Ratio load balancing allows the BIG-IP to distribute traffic based on a predefined weight for each server. This is specifically designed for environments where backend servers have different processing power, ensuring that traffic is weighted appropriately to match each server's specific capabilities and resources.
- ✗
Least Connections
Why it's wrong here
Least Connections distributes traffic based on the number of active connections. While useful for dynamic load, it does not account for differences in server hardware specifications. A small server could still become overloaded if it happens to be assigned a few long-running, resource-intensive connections.
- ✗
Observed
Why it's wrong here
Observed load balancing dynamically tracks server performance over time to make distribution decisions. While it can adapt to hardware differences, it relies on historical metrics that may not be accurate during initial spikes or rapid changes in traffic patterns, making it less predictable than Ratio.
