SPLK-1001 Creating Reports, Dashboards and Visualizations Practice Test 4 — 15 Questions

Question 1

Which THREE best practices should be followed when creating dashboards for a large organization with many users?

Accepted Answer

Use scheduled searches instead of real-time to reduce load. Scheduled searches run at defined intervals and cache results, reducing the load on indexers and search heads compared to real-time searches that continuously stream data. This is especially important in large organizations with many users, as real-time searches can consume significant system resources and degrade performance for all users.

Answer

Use multiple base searches per panel for flexibility

Answer

Use exclusively real-time searches for up-to-date data

Question 2

Which TWO options are correct about post-process searches in dashboards?

Accepted Answer

They can reduce search load by reusing base search results. Post-process searches in Splunk dashboards are designed to reduce search load by reusing the results of a base search. Instead of running multiple independent searches against the raw index data, each post-process search operates on the already-completed base search results, which significantly improves dashboard performance and reduces resource consumption.

Answer

They support all SPL commands that base searches support

Answer

They can override the time range of the base search

Answer

They automatically inherit all fields from the base search

Question 3

Refer to the exhibit. The report returns 0 results even though there are error events in the data. What is the most likely issue?

Accepted Answer

The field name is 'error' but the data uses 'ERROR'. Splunk field names are case-sensitive. The search is looking for a field named 'error', but the CSV data contains a field named 'ERROR'. Since the field name does not match exactly, the `stats` command cannot find any events with the field 'error', resulting in zero results. Renaming the field in the search using `rename ERROR as error` or adjusting the field name in the data would resolve this.

Answer

The stats command is misspelled

Answer

The time range is not set

Answer

The CSV file has no header

Question 4

Refer to the exhibit. The pie chart shows only 10 slices, but the base search stats returns all destinations. What is the reason?

Accepted Answer

The post-process search includes | top limit=10 dest. The base search returns all destinations, but the pie chart shows only 10 slices because the post-process search uses the `| top limit=10 dest` command. The `top` command limits the results to the top 10 values of the `dest` field by count, and this post-process search is applied after the base search, so only those 10 slices are displayed in the pie chart.

Answer

The eval command changes the dest field

Answer

The base search time range is too small

Answer

The charting option 'chart' is set to 'pie'

Question 5

Refer to the exhibit. The timechart returns only partial results for some sourcetypes, and there are gaps in the timeline. Which is the most likely reason?

Accepted Answer

The tstats command only uses summary data, which may not cover all time ranges. The `tstats` command in Splunk operates on indexed-time summary data stored in the tsidx files, not on raw events. This summary data is generated during indexing based on the data model acceleration or summary indexing configuration, and it may not cover all time ranges if the acceleration has not been built for those periods or if the data model is not fully accelerated. As a result, `tstats` can return partial results and gaps in the timeline, especially when the time range extends beyond the accelerated data coverage.

Answer

The timechart span=1h conflicts with the tstats span

Answer

The sourcetype field is not summarized

Answer

The where clause is invalid

Question 6

A security analyst creates a report that shows the count of failed login attempts by user over the last 7 days. The report uses the `top` command. However, the report only shows the top 10 users, but the analyst wants to see all users. What should the analyst do?

Accepted Answer

Add the `limit=0` argument to the `top` command.. The `top` command in Splunk defaults to showing the top 10 results. Adding `limit=0` removes this limit, displaying all users with failed login attempts. This is the correct approach because `top` already counts occurrences and sorts them, so the analyst only needs to override the default limit.

Answer

Use the `rare` command instead.

Answer

Change the time range to include more data.

Answer

Use the `stats count by user` command and sort descending.

Question 7

A user wants to create a dashboard panel that shows a single number representing the total number of errors in the last 24 hours. Which visualization type should be used?

Accepted Answer

Single value. A Single Value visualization is designed to display a single numeric metric prominently, making it the ideal choice for showing the total number of errors in the last 24 hours. It directly answers the user's requirement for a single number without any additional chart elements or time-series context.

Answer

Pie chart

Answer

Bar chart

Answer

Line chart

Question 8

A Splunk admin notices that a dashboard panel using `timechart` is showing gaps (null values) for some time periods where no events exist. The admin wants to display a zero instead of null to make the chart continuous. Which command should be added before `timechart`?

Accepted Answer

`fillnull`. `fillnull`, is correct because it explicitly replaces null values with a specified value (default 0) in the results of a transforming command. In Splunk, `fillnull` is used after commands like `timechart` to fill gaps where no events exist. The question asks which command should be added "before `timechart`", but in practice, `fillnull` is placed after `timechart`. However, among the given choices, only `fillnull` can achieve the desired outcome. Option A (`timechart useother=t`) is unrelated to null filling. Option B (`eventstats`) does not replace nulls. Option C (`makecontinuous`) creates time buckets for missing periods but does not fill the null values; it leaves them as null or adds null events. Therefore, `fillnull` is the correct command to use in conjunction with `timechart` to display zeros instead of nulls.

Answer

`timechart useother=t`

Answer

`eventstats`

Answer

`makecontinuous`

Question 9

A dashboard has a radio button input that selects a sourcetype. The panel uses `index=web sourcetype=$source$`. However, when the user selects a sourcetype, the panel doesn't update. What is the most likely cause?

Accepted Answer

The token name in the search is `$source$` but the input token is named `sourcetype`.. The dashboard panel does not update because the token referenced in the search string (`$source$`) does not match the name of the radio button input. In Splunk, a dashboard input creates a token with the name specified in its `token` attribute. If the input's token is named `sourcetype`, the search must use `$sourcetype$` to reference its value. Using `$source$` means the search looks for a token that does not exist, so no substitution occurs and the panel remains static.

Answer

The search includes a `stats` command that ignores the token.

Answer

The panel is a single value panel that does not update dynamically.

Answer

The time range is too short and returns no events.

Question 10

A user wants to create a bar chart showing the count of events by host for the last hour. Which command should be used?

Accepted Answer

`index=* | stats count by host`. `stats count by host` produces a table of hosts and their event counts, which can be directly visualized as a bar chart. The user wants a count of events by host for the last hour, and `stats` with a `by` clause is the appropriate transforming command to aggregate counts per host without time-series splitting.

Answer

`index=* | timechart count by host`

Answer

`index=* | top host`

Answer

`index=* | chart count by host`

Question 11

A report uses `| timechart count by action`. The user wants to show only the top 3 actions and combine all others into a single 'Other' column. Which argument should be added?

Accepted Answer

`limit=3 useother=t`. The `timechart` command in Splunk uses the `limit` argument to control the number of distinct series (columns) displayed. Adding `limit=3` restricts the output to the top 3 values by count, and `useother=t` automatically groups all remaining values into a single 'Other' column. Without `useother=t`, the extra values are simply dropped, not aggregated.

Answer

`limit=3`

Answer

`useother=t`

Answer

`other=t`

Question 12

A dashboard includes a pie chart showing the distribution of error types. The data comes from a search that uses `top` command. The pie chart is showing a slice labeled 'Other' that is very large. What is the most likely cause?

Accepted Answer

The `top` command default limit is 10, grouping remaining into 'Other'.. The `top` command in Splunk by default returns the top 10 most common values and groups all remaining values into an 'Other' category. If the pie chart shows a very large 'Other' slice, it indicates that the default limit of 10 is too low for the dataset, causing many distinct error types to be lumped together. Option D correctly identifies this default behavior as the most likely cause.

Answer

The `top` command is using `limit=0` which shows all values.

Answer

The search uses `rare` instead of `top`.

Answer

The pie chart has a maximum number of slices set to 5.

Question 13

A user wants to add a trend indicator to a single value visualization showing whether the count increased or decreased compared to the previous period. Which feature should be used?

Accepted Answer

Comparison. The Comparison feature in a single value visualization allows you to show a trend indicator (e.g., an up or down arrow) that compares the current value to a previous time period, such as the previous week or month. This directly answers the user's need to see whether the count increased or decreased compared to the previous period. It is configured in the 'Single Value' visualization options under 'Comparison' settings.

Answer

Trendline

Answer

Color coding

Answer

Sparkline

Question 14

A dashboard has multiple panels that use the same base search. The admin wants to avoid running the same search multiple times. Which feature should be used?

Accepted Answer

Post-process search. Post-process searches allow a dashboard panel to run a secondary search against the results of a base search, rather than re-running the original search against the index. This avoids redundant data retrieval and processing, as the base search runs once and its results are stored in a results server, which subsequent post-process searches query using the `| search` command or similar filtering.

Answer

Report acceleration

Answer

Data model

Answer

Summary indexing

Question 15

A dashboard designer wants to create a drilldown from one chart to another dashboard. Which TWO actions must be configured? (Select two.)

Accepted Answer

Set the target dashboard's token to accept the drilldown value. Options D and E are correct because for a drilldown from one chart to another dashboard, you must set the source chart's drilldown action to 'link to dashboard' (option E) and configure the target dashboard to accept a token from the drilldown (option D). Option A is incorrect because adding a search command is not required for drilldowns. Option B is incorrect because 'link to search' opens a search, not a dashboard. Option C is not necessary; while dashboard permissions control access, they are not part of the drilldown configuration.

Answer

Add a search command to the chart

Answer

Set the source chart's drilldown to 'link to search'

Answer

Enable dashboard permissions
