SPLK-1002 Advanced Searching and Statistics Practice Question
Exhibit
index=web | eval status_category=case(status>=500, "Server Error", status>=400, "Client Error", 1=1, "Other") | stats count by status_category
Refer to the exhibit. What is the purpose of the eval command in this search?
⚠ Common exam trap
Splunk often tests the distinction between creating a new field versus modifying an existing field, and candidates mistakenly think eval replaces the original field when it actually adds a new one.

Correct answer & explanation
✓
It creates a new field 'status_category' based on the numeric status code, grouping into three categories.
The eval command creates a new field 'status_category' by evaluating a CASE expression that maps numeric HTTP status codes (e.g., 200, 404, 500) into three descriptive categories: 'OK', 'Client Error', and 'Server Error'. This is a common pattern for enriching raw data with human-readable labels without altering the original 'status' field. The correct answer is D because the search explicitly defines the new field based on the status code values.
