• To create an alert based on the page load experience of most users, the alerting level must be based on percentile_duration_90.No
• To create an alert based on the page load experience of most users, the alerting level must be based on percentile_duration_95.Yes
• To create an alert based on the page load experience of most users, the alerting level must be based on threshold.No
• To only create an alert when authentication error occurs on the server, the query must be filtered on item Type.No
• To only create an alert when authentication error occurs on the server, the query must be filtered on resultCode.Yes
• To only create an alert when authentication error occurs on the server, the query must be filtered on source.No
• To only create an alert when authentication error occurs on the server, the query must be filtered on success.No

Explanation

The correct answer is 'Yes' for percentile_duration_95 because the 95th percentile represents the page load experience for the vast majority (95%) of users, making it the most representative metric for alerting on 'most users' page load performance. The 50th percentile (median) only represents the midpoint of users, and while useful, it doesn't capture the experience of users with slower load times. The 90th percentile is closer but still excludes a significant portion of users who may be experiencing poor performance.
