You are working in Azure Data Explorer Web UI. You want to enable Error level highlighting for interpreting the verbosity or severity level of every row in the result panel and have them coloured accordingly. To enable the error level highlighting, the column needs to be of one of some supported types. From the below-given list, choose the column types that are supported? 
 

Answer options:

A.Int
B.Double
C.Long
D.String
E.Float
F.Boolean
G.Enum

Correct Answers: A, C and D 
There are some specific column requirements for error level highlighting. For highlighted error levels, the column needs to be of type long, int, or string. If the column type is int or long:
<ul style="list-style-type:circle">
The name of the column must be Level
It may only contain numbers between 1 and 5.
If the column type is the string:
<ul style="list-style-type:circle">
Having the name of the column Level is optional. It will help in improving the performance.
The column may have only the following values:
crit, critical, assert, fatal, high
error, e
warning, s
w, warning, monitor
information
verbose, verb, d
Option A is correct. Int is a valid datatype for the column for error level highlighting.
Option B is incorrect. Double is not a valid data type for the column for error level highlighting.
Option C is correct. Long is a valid datatype for the column for error level highlighting.
Option D is correct. String is a valid datatype for the column for error level highlighting.
Option E is incorrect. Float is not a valid datatype for the column for error level highlighting.
Option F is incorrect. Boolean is not a valid datatype for the column for error level highlighting.
Option G is incorrect. Enum is not a valid datatype for the column for error level highlighting.
