A company purchased a NetScaler Pooled Capacity license. What is the main benefit of pooled capacity licensing compared to fixed per-appliance licenses?

1. It permanently binds the license to a single hardware serial number
2. Each appliance receives unlimited throughput regardless of the license size
3. It removes the need to enable individual features
4. Bandwidth and instance capacity can be allocated from a shared license pool and reallocated across appliances on demand
