Answers

Set Threshold Sensitivity to Low
E.
Set Force Plan to On
Answers
E.
Set Force Plan to On
Suggested answer: B, D

Explanation:

B: Dynamic Thresholds continuously learns the data of the metric series and tries to model it using a set of algorithms and methods. It detects patterns in the data such as seasonality (Hourly / Daily / Weekly), and is able to handle noisy metrics (such as machine CPU or memory) as well as metrics with low dispersion (such as availability and error rate). D: Alert threshold sensitivity is a high-level concept that controls the amount of deviation from metric behavior required to trigger an alert. Low - The thresholds will be loose with more distance from metric series pattern. An alert rule will only trigger on large deviations, resulting in fewer alerts. Incorrect Answers:

A: High - The thresholds will be tight and close to the metric series pattern. An alert rule will be triggered on the smallest deviation, resulting in more alerts.
