Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
dataset = xdr_data, cloud_trail | correlate on actor_username
Why it's wrong here
'correlate' is used for correlation rules, not standard ad-hoc dataset joining in XQL.
- ✗
dataset = xdr_data | lookup dataset = cloud_trail on actor_username
Why it's wrong here
'lookup' is used for enriching data from lookup tables, not joining two arbitrary event datasets.
- ✓
dataset = xdr_data | join type=inner dataset = cloud_trail on actor_username = username
Why this is correct
This correctly utilizes the join command with the join type and the on clause.
- ✗
dataset = xdr_data | merge dataset = cloud_trail where actor_username == username
Why it's wrong here
'merge' is not the XQL command for joining datasets.
