Which DNS policy flag defines the duration window over which DNS rate limiting is calculated?

• A. -threshold
• B. -timeSlice
• C. -selectorName
• D. -preferredLocation

Answer: (B)

The key idea is how long the system looks back to count DNS requests for rate limiting. The timeSlice flag defines that duration—the length of each window in which requests are tallied and compared to the threshold. For example, with a 60-second timeSlice, each 60-second window is evaluated separately, and if the number of requests in that window exceeds the threshold, the policy is triggered. The threshold flag sets how many requests are allowed in each window, but it doesn’t define how long the window lasts. The selectorName flag chooses which policy applies, and the preferredLocation flag affects where the policy is applied, not the timing. So, timeSlice is the flag that defines the duration window over which DNS rate limiting is calculated.
