• A1
• B2
• C3
• D4

• B
  90% (19)
• C
  5% (1)

Explanation

Citrix leading practices mandate a minimum of 2 Delivery Controllers for any production deployment, regardless of user count, because redundancy is a core requirement - if one controller fails, the other maintains session brokering and keeps users connected. Option A (1 controller) creates a single point of failure, which violates Citrix's own leading practices even for small environments. Options C and D (3 or 4) may be appropriate for larger or enterprise-scale deployments but exceed the minimum threshold the question asks about, making them incorrect in this context.

Memory tip: Think "2 for HA" - Citrix always requires at least 2 Delivery Controllers for High Availability, just like you'd never deploy a single domain controller. If you see "minimum" and "leading practices" together in a Citrix question, redundancy (2) is almost always the answer.
