What are the advantages of using Auto-Allocate in an A/B Test? (Select two.)

Question

Options

• AFaster identification of a winning variation
• BEven traffic distribution among all variations
• CReduces overall test cost
• DCustomizable confidence thresholds

• A
  78% (35)
• B
  16% (7)
• D
  7% (3)

Explanation

Auto-Allocate uses a multi-armed bandit algorithm to dynamically shift traffic toward better-performing variations during the test, rather than maintaining a fixed split. This means a winner is identified faster (A) because the algorithm doesn't wait for a fixed sample size - it reallocates traffic in real time as signals emerge. It also reduces cost (C) because fewer users are exposed to underperforming variations, minimizing lost conversions or revenue during the test period (opportunity cost).

B is wrong because even traffic distribution is the behavior of standard A/B testing, not Auto-Allocate - Auto-Allocate does the opposite by skewing traffic toward winners dynamically.

D is wrong because customizable confidence thresholds are a feature of traditional statistical testing frameworks, not a specific advantage of Auto-Allocate, which uses its own internal confidence model to govern reallocation.

Memory tip: Think "Auto-Allocate = Auto-Accelerate" - it speeds up finding the winner (A) and cuts the cost of keeping losers in the race (C). Both benefits stem from the same core behavior: shifting traffic early.
