SPLK-1004 Practice Test 15 — 15 Questions

Question 1

When creating a calculated field, what does the 'EVAL-' prefix in props.conf indicate?

Accepted Answer

It indicates a calculated field definition.. In Splunk's props.conf, the 'EVAL-' prefix defines a calculated field — a field whose value is computed at search time using an expression. For example, EVAL-total = price * quantity creates a field named 'total' derived from other fields. This is the standard syntax for search-time field extraction via calculated fields, and it does not require the field to be indexed.

Answer

It identifies a field for a lookup table.

Answer

It marks the field as a source for an alias.

Answer

It forces the field to be indexed.

Question 2

You want to ensure a macro is only available to a specific user role. Where do you configure this restriction?

Accepted Answer

By editing the permissions setting of the macro object. Macro permissions in Splunk are controlled through the object's permission settings, accessible via Settings > Advanced Search > Search Macros (or the macro's Permissions link). You can set the macro to be private, shared in the app, or shared globally, and you can specify which roles have read or write access. This is the standard way to restrict a macro to a specific role.

Answer

In the user's account profile

Answer

By adding the role to the macros.conf file manually

Answer

In the macro definition itself using a 'role' parameter

Question 3

A Splunk administrator needs to ensure that a data model's acceleration summary is not rebuilt unnecessarily, to conserve system resources. The data model has a root event object and several child objects. The administrator notices that the acceleration job runs frequently and takes a long time. What should be evaluated to optimize the acceleration?

Accepted Answer

The acceleration time range and the acceleration schedule, to align them with the actual data update frequency and required latency.. To avoid unnecessary acceleration rebuilds, the acceleration time range and schedule should be tuned to match how often the underlying data changes and the required data freshness. If data is updated infrequently, a less frequent schedule is sufficient, reducing resource usage.

Answer

The indexer's replication factor, because higher replication increases the amount of data to accelerate.

Answer

The search head's concurrent search limits, as acceleration jobs may be queued and delayed.

Answer

The number of fields in the data model, because having more fields always increases acceleration time.

Question 4

A Splunk power user is creating a data model and wants to add a field that calculates the duration of a session by subtracting the start time from the end time. The user wants this field to be available in Pivot and in tstats searches. What should the user do?

Accepted Answer

Create an eval-based calculated field in the data model.. The correct approach is to create an eval-based calculated field within the data model. This allows the user to define a new field using an expression that subtracts the start time from the end time. Calculated fields are evaluated at search time and are accessible in Pivot and tstats when the data model is accelerated. Other methods like field aliases, lookups, or regex extractions do not support arithmetic calculations on existing fields.

Answer

Use a lookup to precompute the duration and add it as a field.

Answer

Define a regex-based field extraction in the data model.

Answer

Add a field alias in the data model.

Question 5

You are troubleshooting a dashboard that uses a base search and several post-process searches. The base search is `index=app | stats count by user, action`. One post-process search is `| search action=login | top user`. Users report that the top user panel sometimes shows incorrect counts compared to a direct search `index=app action=login | top user`. What is the most likely cause of the discrepancy?

Accepted Answer

The base search uses `stats count by user, action`, which aggregates events, so the post-process search counts aggregated rows rather than raw events.. The base search aggregates events with `stats count by user, action`. The post-process search then operates on these aggregated rows. When it filters for `action=login` and runs `top user`, it counts the number of rows per user, not the sum of event counts. This can produce different results than a direct search on raw events, where `top user` counts actual events. The discrepancy is due to the pre-aggregation in the base search.

Answer

The post-process search is missing a time range, so it uses a different time range than the base search.

Answer

The base search is not using `| fields` to limit the fields passed to post-process searches.

Answer

The base search is not accelerated, so it returns incomplete results.

Question 6

A dashboard has a base search that runs against a large index and takes 30 seconds to complete. Several panels use post-process searches to summarize the base results. Users complain that the dashboard is slow to load and that changing an input causes the entire base search to re-run. Which approach best improves the dashboard's performance?

Accepted Answer

Replace the base search with a scheduled search that populates a summary index, and have the dashboard panels search the summary index.. The dashboard's bottleneck is the expensive base search that scans a large index and re-runs on every load or input change. Precomputing the aggregation with a scheduled search that populates a summary index lets the panels query a small, fast dataset, removing the repeated heavy scan and making the dashboard responsive regardless of input changes.

Answer

Add more post-process searches to distribute the summarization work across panels.

Answer

Increase the dashboard's refresh interval so the base search runs less frequently.

Answer

Convert the base search to use the transaction command to group related events before summarizing.

Question 7

When a workflow action is configured with 'Search' type, what happens if the 'Link URI' field is also populated?

Accepted Answer

The Link URI field is ignored. When a workflow action is configured with type 'Search', the 'Link URI' field is ignored. The action runs a search instead of opening a URI. Therefore, option B is correct. The Link URI is only used when the action type is 'Link'.

Answer

The action fails to execute

Answer

The URI takes precedence

Answer

The search is run, and the URI is opened as a popup

Question 8

A Splunk user wants to create a calculated field that extracts the domain from an email address field named 'email'. The user writes the following eval expression: 'mvindex(split(email, "@"), 1)'. After saving the calculated field, the user notices that the new field 'domain' is not appearing in the Fields sidebar for some events. What is the most likely cause?

Accepted Answer

The field 'email' is not present in all events, so the calculated field cannot be computed for those events.. Calculated fields are only computed when all referenced fields are present in an event. If 'email' is missing, the 'domain' field will not be created, and it will not appear in the Fields sidebar for those events. This is expected behavior and not an error in the expression or configuration.

Answer

The mvindex() function is not supported in calculated fields and only works in the search pipeline.

Answer

The calculated field must be defined in transforms.conf instead of props.conf to work with multivalue fields.

Answer

The eval expression is incorrect because split() returns a multivalue field and mvindex() requires a numeric index.

Question 9

A dashboard uses a base search in a `` element and several panels that reference it with ``. Users report that changing a time token does not update all panels consistently, and some panels show stale data. You need to correct the dashboard so all panels re-run when the token changes. (Choose two.)

Accepted Answer

Ensure each panel search includes the token in its own search string or in the base search it references.. Token-driven refresh requires the token to be both in scope for the panel and referenced in the panel's search. Defining the token at dashboard or global scope and including it in the base or panel search ensures Splunk re-runs the panel when the token value changes. Polling, duplicating searches, or adding drilldown do not establish that dependency.

Answer

Convert all panel searches to inline searches that duplicate the base search logic.

Answer

Add a `<drilldown>` element to each panel to force a re-render when the token changes.

Answer

Set the panels' `refresh` attribute to a fixed interval so they poll for changes.

Question 10

A Splunk power user is troubleshooting a data model acceleration that has stopped generating new summary data. The user checks the Data Model Acceleration settings and the model is enabled and set to accelerate. Which two actions should the user take to resolve the issue? (Choose two.)

Accepted Answer

Check the _internal index for messages from the DataModelAcceleration and search scheduler to identify errors or skipped runs.. Acceleration failures often stem from missing capabilities or errors logged in _internal. Checking that the role has accelerate_datamodel and reviewing _internal for DataModelAcceleration messages will pinpoint the cause. These steps are non-destructive and directly address common permission and scheduling issues that prevent summary generation.

Answer

Restart the search head to clear any stuck acceleration jobs.

Answer

Increase the Max Time setting to 1 year to force a full rebuild of the summary.

Answer

Delete the data model and recreate it from scratch to reset the acceleration state.

Question 11

When creating a workflow action, what does the 'Apply only to the following fields' field do?

Accepted Answer

It restricts the action to only appear when these fields are part of the results. The 'Apply only to the following fields' setting in a workflow action restricts the action so it only appears in the event menu when the specified fields are present in the search results. This ensures the action is contextually relevant and does not appear for events lacking those fields.

Answer

It forces these fields to be extracted

Answer

It filters the results to only include these fields

Answer

It adds these fields to the search query

Question 12

Which attribute in an input element sets the label that the user sees?

Accepted Answer

label. In Simple XML, the label attribute on an input element (e.g., <input type="text" token="tok">) sets the visible text that the user sees next to or above the input field. It is the standard way to provide a human-readable label for dropdowns, text boxes, radio buttons, and other inputs in a dashboard or form.

Answer

text

Answer

name

Answer

display

Question 13

A dashboard uses a base search with a post-process search for each of six panels. Users report that changing the time range picker does not update the panels. The base search includes earliest=-24h latest=now. What is the most likely cause?

Accepted Answer

The base search hard-codes earliest and latest, so the time range picker selection is ignored.. A base search that explicitly sets earliest and latest overrides the dashboard time range picker. To make the picker control the panels, the base search must use tokens for its time range, such as earliest=$earliest$ latest=$latest$, or omit the time range entirely so the picker's values are applied. Post-process searches inherit the base search's results and time context, so the fix belongs in the base search definition.

Answer

The dashboard's time range picker is not connected to the base search because it lacks a 'searchWhenChanged' attribute.

Answer

The post-process searches do not inherit the time range from the base search, so each panel must define its own time range.

Answer

The post-process searches must each include a 'timechart' command to respond to the time picker.

Question 14

A dashboard user reports that a drilldown is not passing the expected token to a target dashboard. The source panel uses a chart where the click event is defined. Which configuration detail should you verify first?

Accepted Answer

Verify the 'click.value' property is correctly set to the field name.. In a dashboard drilldown, the click event must reference the correct token value from the clicked element. For a chart, the click.value property must be set to the field name whose value should be passed, so verifying that property is the first configuration detail to check when the token is not being passed as expected.

Answer

Check if the target dashboard has a Time Range Picker.

Answer

Rebuild the summary index.

Answer

Ensure the user has write permissions to the target dashboard.

Question 15

A Splunk administrator is troubleshooting a data model acceleration issue. The administrator notices that the acceleration summary for the 'Network_Traffic' data model is not up to date, and searches using tstats return stale results. Which two actions should the administrator take to resolve this issue? (Choose two.)

Accepted Answer

Verify that the data model is enabled for acceleration and that the acceleration schedule is properly configured.. Stale acceleration summaries typically occur when acceleration is not running successfully. The administrator should first verify that acceleration is enabled and the schedule is correct, and then review the acceleration logs for errors. These steps identify common issues like misconfiguration or search failures. Other actions like restarting the indexer or forcing a rebuild may be unnecessary or disruptive without first diagnosing the problem.

Answer

Restart the Splunk indexer to force a full re-acceleration of all data models.

Answer

Disable and re-enable acceleration for the data model to trigger a rebuild.

Answer

Check the size of the acceleration summary and increase the disk space if necessary.
