SPLK-2001 Exam Dumps - Splunk Certified Developer

A Splunk custom visualization is a visualization that uses the Splunk Custom Visualization API. This API lets you create your own visualizations using JavaScript, HTML, and CSS. You can also use third-party libraries or frameworks to create custom visualizations. The other options are not custom visualizations, but rather variations of the built-in visualizations in Splunk. For more information, see [Custom visualizations overview].

 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 B because the best way to identify processor bottlenecks of a search is to use the search job inspector. The search job inspector is a tool that provides detailed information about the performance and resource consumption of a search job, such as CPU time, memory usage, scan count, and event count. The search job inspector can help you identify which parts of your search are causing processor bottlenecks and how to optimize them. Option A is incorrect because using the REST API does not provide as much information as the search job inspector. Option C is incorrect because using the Splunk Monitoring Console does not provide information about individual search jobs, but rather about the overall health and performance of your Splunk deployment. Option D is incorrect because searching the Splunk logs using index=“internal” does not provide information about processor bottlenecks, but rather about errors and warnings that occurred during the search execution. You can find more information about the search job inspector in the Splunk Developer Guide.

 The correct answer is A and B because these are the ways to get a list of search jobs. Option A is correct because you can access the Activity > Jobs page in Splunk Web to see the list of search jobs that you have run or that are shared with you. Option B is correct because you can use Splunk REST to query the /services/search/jobs endpoint to get a list of search jobs. Option C is incorrect because the /services/saved/searches endpoint returns a list of saved searches, not search jobs. Option D is incorrect because the /services/search/sid/results endpoint returns the results of a specific search job, not a list of search jobs. You can find more information about search jobs and their endpoints in the Splunk REST API Reference Manual.

The valid request arguments for the REST search endpoints are latest_time=now and earliest_time=-5h@h. These arguments specify the time range for the search, using relative or absolute time modifiers. The other arguments are invalid because they use rt (real-time) modifiers, which are not supported by the REST search endpoints. For more information, see [Specify time modifiers in your search].

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 log file that contains logs that are most relevant to Splunk Web is web_service.log. This log file records information about the web server that runs Splunk Web, such as requests, responses, errors, and performance. The other log files contain logs that are related to other aspects of Splunk, such as audit.log for security events, metrics.log for performance metrics, and splunkd.log for Splunk daemon activity. For more information, see [About Splunk log files].

 The correct answer is A because using Splunk Web to modify config settings for a shared object, a revised config file with those changes is placed in the $SPLUNK_HOME/etc/apps/myApp/local directory. The local directory is where Splunk stores the configuration files that are modified by the user, either through Splunk Web or by editing the files directly. The local directory has the highest priority in the configuration layering scheme, which means it overrides the settings in the default directory. The other options are incorrect because they either use the wrong directory or the wrong priority. You can find more information about the configuration files and the configuration layering scheme in the Splunk Developer Guide.

 The correct answer is B and D, because they are the ways to optimize the searches in the dashboard. A dashboard is a user interface that displays data from one or more searches in various panels, such as charts, tables, or maps. Optimizing the searches in the dashboard helps to improve the dashboard performance, reduce the load on the Splunk server, and enhance the user experience. Restricting the time range of the search as much as possible and converting the common SPL into a Global Search and converting the other searches to post-processing searches are both methods to optimize the searches in the dashboard by limiting the amount of data to be searched or processed. Converting searches to include NOT expressions and replacing | stats command with | transaction command wherever possible are not methods to optimize the searches in the dashboard, but rather ways to change the search logic or functionality, which might not produce the desired results.

 The correct answer is B because when calling the serviceNS endpoint, you must specify the user and app context in the URI. The serviceNS endpoint is a REST endpoint that allows you to access the Splunk service for a specific namespace. The namespace is a combination of the user and the app context, which determine the scope and visibility of the knowledge objects in Splunk. The serviceNS endpoint requires you to specify the user and app context in the URI, such as /servicesNS/{user}/{app}. Option A is incorrect because you do not need to authenticate with an admin user, but rather with the user of the required context. Option C is incorrect because you do not need to authenticate with the user of the required context, but rather with any valid user. Option D is incorrect because you do not need to pass the user and app context in the request payload, but rather in the URI. You can find more information about the serviceNS endpoint and the namespace in the Splunk REST API Reference Manual.

The correct answer is A because the namespace is a combination of the user and the app. The namespace determines the scope and visibility of the knowledge objects in Splunk. The role, the sharing level, and the permissions are not part of the namespace, but they affect the access to the knowledge objects. You can find more information about the namespace and the knowledge objects in the Splunk Developer Guide.

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 types of event handlers are set token and form input. Set token event handlers let you set or unset tokens based on user interactions, such as clicking on a chart or selecting a value from a dropdown. Form input event handlers let you create interactive forms that use tokens to pass values between inputs and searches. The other options are not event handlers, but rather components of a dashboard. For more information, see Event handlers overview.

 The correct answer is B, C, and D, because they are all valid parent elements for the event action shown below. The event action is a element, which is used to set the value of a token based on a user interaction, such as a click or a change. The element can be nested inside a , a , or a element, depending on the type and context of the event. The element is not a valid parent element for the element, but a sibling element that can be used to evaluate an expression and set the value of a token.

 By using visualization drilldown, you can hide or show a panel by clicking on a chart or a table on the same form. Visualization drilldown lets you define a drilldown action that affects a different panel on the same dashboard. You can use the set or unset tokens to control the visibility of the target panel. For more information, see Visualization drilldown.

 The correct answer is A, C, and D because these are the application security best practices that should be adhered to while developing an app for Splunk. Option A is correct because reviewing the OWASP Top Ten List can help you identify and avoid the most common web application security risks. Option C is correct because reviewing the OWASP Secure Coding Practices Quick Reference Guide can help you learn and apply the best practices for secure coding. Option D is correct because ensuring that third-party libraries that the app depends on have no outstanding CVE vulnerabilities can help you prevent potential exploits and attacks. Option B is incorrect because storing passwords in clear text in .conf files is a bad practice that can compromise the security and privacy of your app and your data. You can find more information about the application security best practices in the Splunk Developer Guide.

 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.
