SPLK-2001 Splunk Certified Developer Exam Questions and Answers

The URL that could be used to construct a REST request to search the employee KV Store collection to find records with a rating greater than or equal to 2 and less than 5 is ‘http://localhost:8089/servicesNS/nobody/search/storage/collections/data/ employees?query={%22$and%22:[{%22rating%22:{%22$gte%22:2}},{%22rating%22:{% 22$lt%22:5}}]} &output_mode=json’. This URL uses the query parameter with a valid JSON expression that specifies the rating criteria, and the output_mode parameter with a value of json to return the results in JSON format. The other URLs are either invalid or use incorrect syntax for the query parameter. For more information, see Search a KV Store collection.

 Auto-refresh applies to inline searches and saved searches, and post-processing searches are refreshed when their base searches are refreshed. Enabling auto-refresh for a report does not require editing XML, but rather using the Edit Schedule option in the report menu. Each post-processing search using the same base search cannot have a different refresh time, but rather inherits the refresh time of the base search. For more information, see Set up auto-refresh for dashboard panels.

When output_mode is not used, the title element of a feed is a human readable name for a returned entry. The title element contains the name of the object, such as the name of a saved search or a dashboard. The other elements are not human readable names, but rather identifiers, links, or authors of the entry. For more information, see Access Splunk data using feeds.

The correct answer is B, because the tstats command can be used to perform statistical queries on indexed fields in TSIDX files. TSIDX files are files that store the index data for Splunk, such as the events, timestamps, and fields. Indexed fields are fields that are extracted and stored in the TSIDX files at index time, which makes them faster to search than non-indexed fields. The tstats command is a search command that performs statistical calculations on indexed fields, such as count, sum, avg, and so on. The tstats command is faster than the stats command, which performs statistical calculations on any fields, because it does not need to retrieve the events from the index, but only the fields from the TSIDX files. The other options are not search commands that can be used to perform statistical queries on indexed fields in TSIDX files. The stats command performs statistical calculations on any fields, not just indexed fields. The tscollect command collects the results of a transforming search and writes them to a TSIDX file. The transaction command groups events into transactions based on common values.

The correct answer is A and B, because _audit and _internal are the indexes that contain log files related to Splunk REST calls. The _audit index stores information about user activities, such as login attempts, searches, and saved reports. The _internal index stores information about Splunk components, such as splunkd, metrics, and REST calls.

 The containers that are included in the Atom Feed response when using the Splunk REST API are , , and . The feed container represents the entire response, the entry container represents each individual result, and the content container represents the fields and values of each result. The namespace container is not included in the Atom Feed response, but rather in the XML namespace declaration. For more information, see Access Splunk data using feeds.

 The correct answer is D, because ensuring components have no Common Vulnerabilities and Exposures (CVE) vulnerabilities is a security best practice for developing Splunk apps. CVE is a list of publicly disclosed information security vulnerabilities and exposures1. Splunk recommends using tools such as npm audit, retire.js, and snyk to scan your app components for CVE vulnerabilities2.

The correct answer is A, because visualization event handler uses the element to support pan and zoom functionality. Visualization event handler is a type of event handler that enables you to interact with custom visualizations3. The element defines the behavior of the visualization when the user selects a region of the chart. It supports attributes such as pan and zoom4.

 The correct answer is A, B, and C, because they are all ways to monitor app performance. App performance refers to how well an app performs its intended functions, such as data ingestion, search, visualization, and alerting. Monitoring app performance helps to identify and troubleshoot issues, optimize performance, and improve user experience. Using Splunk logs, using the search job inspector, and using the Monitoring Console are all methods to monitor app performance by collecting and analyzing various metrics and data related to the app. Using the storage/collections/config REST endpoint is not a way to monitor app performance, but a way to configure the KV Store collections for an app.

The correct answer is A, because tokenn​ame∣s ensures that quotation marks surround the value referenced by the token. The |s modifier is used to escape special characters in the token value, such as quotation marks, commas, and colons. This is useful when the token value is used in a search string or a drilldown action1. The other options are incorrect because they either do not escape the special characters or add extra quotation marks.

The correct answer is A, C, and D because these are the valid values for the sharing property of the Access Control List (ACL) when updating a knowledge object via REST. The sharing property determines the scope of the knowledge object and who can access it. The value of the User is not valid for the sharing property. You can find more information about the ACL and its properties in the Splunk REST API Reference Manual.

 The correct answer is A, B, and C because these are the possible reasons why the dashboard is not seen after moving myApp to a different Splunk instance. Option A is correct because if the dashboard’s permissions were set to private, only the owner of the dashboard can see it on the new instance. Option B is correct because if the user role permissions are different on the new instance, the user may not have access to the dashboard. Option C is correct because if the admin deleted the myApp/local directory before packaging, the dashboard configuration may have been lost. Option D is incorrect because changes placed in $SPLUNK_HOME/etc/apps/search/default/data/ui/nav do not affect the visibility of the dashboard. You can find more information about dashboard permissions and configuration in the Splunk Developer Guide.

The correct answer is A and D, because configuring a WMI input and using a Windows universal forwarder are the ways to collect event logs from a remote Windows machine using a standard Splunk installation and no customization. WMI input is a type of input that collects Windows Management Instrumentation (WMI) data from remote Windows machines. Windows universal forwarder is a lightweight version of Splunk that can forward data from Windows machines to Splunk indexers.

The type of vulnerability in the Python code snippet is CWE-404: Improper Resource Shutdown or Release. This vulnerability occurs when a resource is not released or closed properly after use, which can lead to resource exhaustion or unexpected behavior. In this case, the open() and readline() commands could fail to close the file handle, which could prevent other processes from accessing the file or cause a memory leak. The other types of vulnerabilities are not relevant to this scenario. For more information, see CWE-404: Improper Resource Shutdown or Release.

When the same search is required from a REST API call, all the fields will be given, including _raw, name, sourcetype, and instantaneous_kbps. This is because the default output mode for the REST API is XML, which returns all the fields and values for each event. To limit the fields returned, you can use the output_mode parameter with a value of json_cols, json_rows, or csv. For more information, see Access Splunk data using feeds.

The correct answer is B, C, and D, because they are all security best practices for Splunk app development. Storing passwords in clear text in .conf files is not a security best practice, because it exposes the passwords to unauthorized access or leakage. Implementing security in software development lifecycle means applying security principles and practices throughout the app development process, from design to deployment. Manually testing application with the controls listed in the OWASP Security Testing Guide helps to identify and mitigate common security risks and vulnerabilities in web applications. Using a dynamic scanner such as OWASP ZAP to scan web application components for vulnerabilities helps to automate the security testing and find potential issues that might be missed by manual testing.

The endpoint that is used to authenticate with the Splunk REST API is /services/auth/login. This endpoint returns a session key that can be used for subsequent requests to the Splunk REST API. The other endpoints are either invalid or used for different purposes. For more information, see Authenticate with the Splunk REST API.

The correct answer is C and D because these are the valid post-processing searches. A post-processing search is a type of search that applies additional filters or transformations to the results of a base search. A post-processing search can use any SPL command that does not require access to the raw data, such as stats, search, eval, and chart. Option C is correct because it uses the stats command to aggregate the count by log level. Option D is correct because it uses the search command to filter the results by log level and then uses the stats command to aggregate the count by component. Option A is incorrect because it uses the tstats command, which is not a valid post-processing command, as it requires access to the raw data. Option B is incorrect because it uses the sourcetype field, which is not available in the results of the base search, as it only returns the component and log_level fields. You can find more information about the post-processing searches in the Splunk Developer Guide.
