In a Citrix ADC load balancing setup, which load-balancing method is used by default at startup of a vServer?

• A. Least Connections
• B. Least Bandwidth
• C. Custom Load
• D. Round-robin

Answer: (D)

Round robin is used because it provides a simple, fair distribution when a vServer starts and there aren’t yet metrics to gauge current load. It cycles requests through each available server in order, giving an even start-up spread without needing to know which servers are busier or more capable.

This default makes sense because it doesn’t depend on real-time stats like active connections or bandwidth, which may not be established at startup. Once the pool has health and performance data, you can switch to methods that bias distribution based on current load, such as least connections or least bandwidth, or use a custom approach if you have specific criteria.
