Pearson SPLK-1004 New Attempt

In Splunk, the Admin role (Option D) has the capability to use the Log Event alert action among many other administrative privileges. The Log Event alert action allows Splunk to create an event in an index based on the triggering of an alert, providing a way to log and track alert occurrences over time. The Admin role typically encompasses a wide range of permissions, including the ability to configure and manage alert actions.

The append command in Splunk is often used with a subsearch to add additional data to the end of the primary search results, and it can access historical data (Option B). This capability is useful for combining datasets from different time ranges or sources, enriching the primary search results with supplementary information.

The fieldsummary command in Splunk generates statistical summaries of fields in the search results, including the count of events that contain the field (count) and the distinct count of field values (dc). These summaries provide insights into the prevalence and distribution of fields within the dataset, which can be valuable for understanding the data's structure and content. Standard deviation (stdev) and mean (mean) are not directly provided by fieldsummary but can be calculated using other commands like stats for fields that contain numerical data.

Using report acceleration (Option C) is a performance improvement technique unique to dashboards in Splunk. Report acceleration involves pre-computing the results of a report (which can be a saved search or a dashboard panel) and storing these results in a summary index, allowing dashboards to load faster by retrieving the pre-computed data instead of running the full search each time. This technique is especially useful for dashboards that rely on complex searches or searches over large datasets.
