Splunk SPLK-1002 Splunk Core Certified Power User Exam Practice Test

Answer : A

The objective is to group all events that share the same JSESSIONID value and filter them by a specific JSESSIONID.

Option A: This uses the transaction command with the JSESSIONID field to group all events sharing the same session ID and filters for the specific value SD497K117O2F098. This is correct.

Option B: The syntax here is invalid because JSESSIONID <value> is not a proper search syntax.

Option C: The highlight command only highlights fields or values in events; it does not group them.

Option D: While this filters for events containing SD497K117O2F098, it does not group them by JSESSIONID.

Answer : C

Field aliases in Splunk are used to map field names in event data to alternate names to make them easier to understand or consistent across datasets.

Option A (Tags): Field aliases are not directly applied to tags. Tags are used for categorizing events or field values.

Option B (Indexes): Field aliases cannot be applied to indexes. Indexes are physical storage locations for events in Splunk.

Option C (Sourcetypes): This is correct. Field aliases can be defined at the sourcetype level to ensure consistent naming across events of the same sourcetype.

Option D (Event types): Event types are saved searches, and field aliases do not apply here directly.

Answer : C

The fillnull command in Splunk is used to replace null (missing) field values with a specified value.

Explanation of options:

A: Incorrect, as fillnull does not set fields to null; it fills null values with a specific value.

B: Incorrect, as the command only affects the specified field (src in this case).

C: Correct, as the fillnull command explicitly sets null values in the src field to 'Unknown'.

D: Incorrect, as only the src field is affected, not all fields.

Example:

If the src field is null for some events, fillnull will populate 'Unknown' in those cases.

Answer : B

Tags in Splunk allow users to assign multiple field-value pairs to a common label.

The correct syntax to filter by tag is tag::<field>=<tag_name>.

tag::team=SpecialProjectX will filter results where team=support is associated with the tag SpecialProjectX.

tag=SpecialProjectX searches for all events associated with SpecialProjectX, not just the support team.

tag::Support-SpecialProjectX is incorrect syntax.

tag!=Fuji,Austin is incorrect since it does not filter using the SpecialProjectX tag.

Answer : D

In Splunk, the eval command is often used for manipulating field values, including concatenation. The correct way to concatenate a string and a number is to use the . (period) operator. This operator joins different types of data into a single string value.

For example:

eval concatenated_value = 'value_' . 123

Result: concatenated_value will be value_123.

Other operators:

& is not a valid operator in eval for concatenation.

+ is used for arithmetic addition, not concatenation.

- is also not a concatenation operator.

Answer : C

In this case, the outer join is applied, which means that all rows from the outer (left) table will be included, even if there are no matching rows in the inner (right) table. The result will include all five rows from the outer table, with the matched data from the inner table where employeeNumber matches. Rows without matching employeeNumber values will have null values for the fields from the inner table.

Answer : B

In Splunk, macros that accept arguments are defined with placeholders for those arguments in the format example(var1, var2). In the search example(100,200), '100' and '200' are the values passed for var1 and var2 respectively.
