Exam DP-100 topic 5 question 26 discussion

To reduce the effect of user data on aggregated results, you should use a smaller value of the differential privacy parameter, also known as epsilon or ε. This parameter controls the level of privacy and the amount of noise added to the data. A smaller epsilon means more noise and less influence of any individual record on the output of the analysis.

C. A lower epsilon reduces the impact of an individual's data on aggregated results, increasing privacy and reducing accuracy

A lower epsilon reduces the impact of an individual's data on aggregated results, increasing privacy and reducing accuracy https://learn.microsoft.com/zh-tw/training/modules/explore-differential-privacy/5-knowledge-check

"The lower the epsilon, the less impact an individual's data has on aggregated results, and therefore the risk of exposure is reduced." See https://docs.microsoft.com/en-us/training/modules/explore-differential-privacy/5-knowledge-check

"You need to reduce the effect of user data on aggregated results" should be B
