The fields sidebar does not show________. (Select all that apply.)
Correct Answer: C
The fields sidebar is a panel that shows the fields that are present in your search results2. The fields sidebar does not show all extracted fields, which are fields that are extracted from your raw data using various methods such as regular expressions, delimiters or key-value pairs2. The fields sidebar only shows selected fields and interesting fields2. Selected fields are fields that you choose to display in your search results by clicking on them in the fields sidebar or by using the fields command2. Interesting fields are fields that appear in at least 20 percent of events or have high variability among values2. Therefore, option C is correct, while options A and B are incorrect because they are types of fields that the fields sidebar does show.
Question 77
These allow you to categorize events based on search terms. Select your answer.
Correct Answer: D
Question 78
A calculated field is a shortcut for performing repetitive, long, or complex transformations using which of the following commands?
Correct Answer: D
The correct answer is D. eval. A calculated field is a field that is added to events at search time by using an eval expression. A calculated field can use the values of two or more fields that are already present in the events to perform calculations. A calculated field can be defined with Splunk Web or in the props.conf file.They can be used in searches, reports, dashboards, and data models like any other extracted field1. A calculated field is a shortcut for performing repetitive, long, or complex transformations using the eval command. The eval command is used to create or modify fields by using expressions.The eval command can perform mathematical, string, date and time, comparison, logical, and other operations on fields or values2. For example, if you want to create a new field named total that is the sum of two fields named price and tax, you can use the eval command as follows: | eval total=price+tax However, if you want to use this new field in multiple searches, reports, or dashboards, you can create a calculated field instead of writing the eval command every time. To create a calculated field with Splunk Web, you need to go to Settings > Fields > Calculated Fields and enter the name of the new field (total), the name of the sourcetype (sales), and the eval expression (price+tax). This will create a calculated field named total that will be added to all events with the sourcetype sales at search time.You can then use the total field like any other extracted field without writing the eval expression1. The other options are not correct because they are not related to calculated fields. These options are: A: transaction: This command is used to group events that share some common values into a single record, called a transaction.A transaction can span multiple events and multiple sources, and can be useful for correlating events that are related but not contiguous3. B: lookup: This command is used to enrich events with additional fields from an external source, such as a CSV file or a database. A lookup can add fields to events based on the values of existing fields, such as host, source, sourcetype, or any other extracted field. C: stats: This command is used to calculate summary statistics on the fields in the search results, such as count, sum, average, etc. It can be used to group and aggregate data by one or more fields.

Question 79
Which of these stats commands will show the total bytes for each unique combination of page and server?
Correct Answer: B
The correct command to show the total bytes for each unique combination of page and server is index=web | stats sum (bytes) BY page server. In Splunk, the stats command is used to calculate aggregate statistics over the dataset, such as count, sum, avg, etc. When using the BY clause, it groups the results by the specified fields. The correct syntax does not include commas or the word 'AND' between the field names. Instead, it simply lists the field names separated by spaces within the BY clause. Reference: The usage of the stats command with the BY clause is confirmed by examples in the Splunk Community, where it's explained that stats with a by foo bar will output one row for every unique combination of the by fields1.
