Exam JN0-253 Topic 6 Question 98 Discussion

InJuniper Mist AI, the concept of aBad User Minute (BUM)is a core metric used withinService Level Expectations (SLEs)and theAI-driven analytics engineto quantify negative user experience.
According to theJuniper Mist AI Operations and SLE Analytics Guide, a "bad user minute" is defined as:
"A normalized measure that represents one minute of degraded user experience for one user." Mist AI calculates this by multiplying the number of affected users by the number of minutes they experience poor performance. This allows administrators to understand the impact of network issues not just in duration, but in terms of total user experience degradation.
For example, if ten users experience poor connectivity for one minute, the system records10 bad user minutes
. This normalization helps Juniper Mistprioritize incidents based on impact, rather than duration alone, allowing administrators to focus on issues that affect the greatest number of users.
Therefore:
* Bis correct - it's a way to normalize a user's negative experience.
* Dis correct - it's calculated asnumber of affected users × number of minutes affected.
