Free and Premium Splunk SPLK-1003 Dumps Questions Answers

" The btool command simulates the merging process using the on-disk conf files and creates a report showing the merged settings. "

" The report does not necessarily represent what ' s loaded in memory. If a conf file change is made that requires a service restart, the btool report shows the change even though that change isn ' t active. "

A Splunk Universal Forwarder is configured as a deployment client by setting the deployment server polling address. The CLI command used for this is:

$SPLUNK_HOME/bin/splunk set deploy-poll < deployment_server > : < management_port >

The management port is usually 8089 unless it has been changed.

Example:

/splunk set deploy-poll deploymentserver.example.com:8089

This command tells the Universal Forwarder to poll the deployment server for apps and configuration updates.

Option B is incorrect because splunk join d.server is not a valid Splunk CLI command.

Option C is incorrect because set deploy-server is not the correct CLI syntax for configuring a deployment client.

Option D is incorrect because join deploy-poll is not a valid Splunk CLI command.

The correct answer is D. The timezone of the forwarder will be added to the event as part of indexing.

According to the Splunk documentation1, Splunk software determines the time zone to assign to a timestamp using the following logic in order of precedence:

Use the time zone specified in raw event data (for example, PST, -0800), if present.

Use the TZ attribute set in props.conf, if the event matches the host, source, or source type that the stanza specifies.

If the forwarder and the receiving indexer are version 6.0 or higher, use the time zone that the forwarder provides.

Use the time zone of the host that indexes the event.

In this case, the event does not have a time zone specified in the raw data, nor does it have a TZ attribute set in props.conf. Therefore, the next rule applies, which is to use the time zone that the forwarder provides. A universal forwarder is a lightweight agent that can forward data to a Splunk deployment, and it knows its systemtime zone and sends that information along with the events to the indexer2. The indexer then converts the event time to UTC and stores it in the _time field1.

The other options are incorrect because:

A. Universal Coordinated Time (UTC) is not the time zone that Splunk adds to the event as part of indexing, but rather the time zone that Splunk uses to store the event time in the _time field. Splunk software converts the event time to UTC based on the time zone that it determines from the rules above1.

B. The timezone of the search head is not relevant for indexing, as the search head is a Splunk component that handles search requests and distributes them to indexers, but it does not process incoming data3. The search head uses the user’s timezone setting to determine the time range in UTC that should be searched and to display the timestamp of the results in the user’s timezone2.

C. The timezone of the indexer that indexed the event is only used as a last resort, if none of the other rules apply. In this case, the forwarder provides the time zone information, so the indexer does not use its own time zone1.

SAML is an open standard for exchanging authentication and authorization data between parties, especially between an identity provider and a service provider1. SAML supports multi-factor authentication by allowing the identity provider to require the user to present two or more factors of evidence to prove their identity2. For example, the user may need to enter a password and a one-time code sent to their phone, or scan their fingerprint and face.

This option corresponds to the file path “$SPLUNK_HOME/etc/apps/splunk_TA_nginx/local/inputs.conf”. This is the configuration file that the user needs to edit to ingest the NGINX access logs to ensure it remains unaffected after upgrade. This is explained in the Splunk documentation, which states:

The local directory is where you place your customized configuration files. The local directory is empty when you install Splunk Enterprise. You create it when you need to override or add to the default settings in a configuration file. The local directory is never overwritten during an upgrade.

The correct answer is C. Distributed search is the feature that allows search heads in a company’s European offices to search data in their New York offices. Distributed search also enables restricting access to certain indexers by using the splunk_server field or the server.conf file1.

Distributed search is a way to scale your Splunk deployment by separating the search management and presentation layer from the indexing and search retrieval layer. With distributed search, a Splunk instance called a search head sends search requests to a group of indexers, or search peers, which perform the actual searches on their indexes. The search head then merges the results back to the user2.

Distributed search has several use cases, such as horizontal scaling, access control, and managing geo-dispersed data. For example, users in different offices can search data across the enterprise or only in their local area, depending on their needs and permissions2.

The other options are incorrect because:

A. Indexer clustering is a feature that replicates data across a group of indexers to ensure data availability and recovery. Indexer clustering does not directly affect distributed search, although search heads can be configured to search across an indexer cluster3.

B. LDAP control is a feature that allows Splunk to integrate with an external LDAP directory service for user authentication and role mapping. LDAP control does not affect distributed search, although it can be used to manage user access to data and searches.

D. Search head clustering is a feature that distributes the search workload across a group of search heads that share resources, configurations, and jobs. Search head clustering does not affect distributed search, although the search heads in a cluster can search across the same set of indexers.

The correct command is:

splunk btool check

The btool check command is used to check Splunk configuration files for syntax errors and malformed stanzas. If Splunk reports a message such as “typo in stanza,” this usually means there is an error in a .conf file, such as an invalid stanza header, misspelled setting, or malformed configuration entry.

btool diag, btool repair, and btool validate are not the correct commands for this purpose.

Per the provided reference

" To set the default username and password, place user-seed.conf in $SPLUNK_HOME/etc/system/local. You must restart Splunk to enable configurations. If the $SPLUNK_HOME/etc/passwd file is present, the settings in this file (user-seed.conf) are not used. "

When using a directory monitor input, specific source types can be selectively overridden using the props.conf file. According to the Splunk documentation1, “You can specify a source type for data based on its input and source. Specify source type for an input. You can assign the source type for data coming from a specific input, such as /var/log/. If you use Splunk Cloud Platform, use Splunk Web to define source types. If you use Splunk Enterprise, define source types in Splunk Web or by editing the inputs.conf configuration file.” However, this method is not very granular and assigns the same source type to all data from an input. To override the source type on a per-event basis, you need to use the props.conf file and the transforms.conf file2. The props.conf file contains settings that determine how the Splunk platform processes incoming data, such as how to segment events, extract fields, and assign source types2. The transforms.conf file contains settings that modify or filter event dataduring indexing or search time2. You can use these files to create rules that match specific patterns in the event data and assign different source types accordingly2. For example, you can create a rule that assigns a source type of apache_error to any event that contains the word “error” in the first line2.

" In the input segment, Splunk software consumes data. It acquires the raw data stream from its source, breaks in into 64K blocks, and annotates each block with some metadata keys. "

A Heavy Forwarder is a Splunk instance that can parse and filter data before forwarding it to another Splunk instance, such as an indexer1. A Heavy Forwarder can also perform index-time field extractions using the TRANSFORMS setting2.

The TRANSFORMS setting is used to configure data transformations in the transforms.conf file3. The transforms.conf file contains settings and values that you can use to configure host and source type overrides, anonymize sensitive data, route events to different indexes, create index-time and search-time field extractions, and set up lookup tables3.

The TRANSFORMS setting can be deployed to the Heavy Forwarder where the syslog files are being monitored, so that the logs can be rerouted based on the event message before they are forwarded to the indexer2. This can improve the performance and efficiency of data processing and indexing2.

According to the Splunk system admin course PDF, When adding native users, Username and Password ARE REQUIRED

In Splunk Enterprise, license warnings occur when the daily indexing volume exceeds the licensed quota. These warnings are tracked from midnight to midnight based on the system clock of the license manager. If the number of warnings surpasses the allowed threshold within a specified period, a license violation ensues, potentially restricting search capabilities.

To prevent a license warning from escalating to a violation, administrators have until midnight to address the issue. The recommended action is toadd a new licenseto the license manager before midnight. This increases the daily indexing volume quota, ensuring that the current day ' s data ingestion falls within the permissible limits.

It ' s important to note that deleting data from indexers or the license manager does not retroactively reduce the recorded license usage for the day. Once data is indexed, it contributes to the day ' s license volume, and its removal does not negate that contribution.

splunk_server

The splunk server field contains the name of the Splunk server containing the event. Useful in a distributed Splunk environment. Example: Restrict a search to the main index on a server named remote. splunk_server=remote index=main 404

" When ingesting event data, the measured data volume is based on the new raw data that is placed into the indexing pipeline. Because the data is measured at the indexing pipeline, data that is filetered and dropped prior to indexing does not count against the license volume qota. "

In Splunk Enterprise, when collecting data from remote Windows machines using Windows Management Instrumentation (WMI), the configurations are defined in the wmi.conf file. This file specifies the parameters for connecting to WMI providers and defines the data inputs.

The wmi.conf file is located in the $SPLUNK_HOME\etc\system\local\ directory. It contains stanzas that define global settings and input-specific configurations for WMI data collection. This setup allows Splunk to collect various types of data from remote Windows systems, such as event logs and performance metrics, without requiring a forwarder on the remote machine.

The answer to your question is C. services/data/collector. This is the endpoint URI used to collect data in a customer managed Splunk Enterprise environment.According to the Splunk documentation1, “The HTTP Event Collector REST API endpoint is /services/data/collector.You can use this endpoint to send events to HTTP Event Collector on a Splunk Enterprise or Splunk Cloud Platform deployment.” You can also use this endpoint to send events to a specific token or index1. For example, you can use the following curl command to send an event with the token 578254cc-05f5-46b5-957b-910d1400341a and the index main:

curl -k -H ' Authorization: Splunk 578254cc-05f5-46b5-957b-910d1400341a ' -d ' { " index " : " main " , " event " : " Hello, world! " } '

Specifies a comma-separated list of tcpout group names. Use this setting to selectively forward your data to specific indexers by specifying the tcpout groups that the forwarder should use when forwarding the data. Define the tcpout group names in the outputs.conf file in [tcpout: < tcpout_group_name > ] stanzas. The groups present in defaultGroup in [tcpout] stanza in the outputs.conf file.

The Universal Forwarder (UF) handles data forwarding to indexers. When monitoring a continuous and high-volume syslog stream over TCP, the UF may not detect an end-of-file (EOF) condition, which is typicallyrequired to trigger load balancing between multiple indexers. This can result in the UF continuously sending data to a single indexer, potentially leading to uneven load distribution.

To address this, Splunk provides the forceTimebasedAutoLB setting in the outputs.conf configuration file. Enabling this setting allows the UF to switch between indexers at regular time intervals, regardless of EOF detection. This ensures a more balanced distribution of data across multiple indexers, even in scenarios with continuous data streams like syslog.

- etc/system/local/ has better precedence at index time - for identical settings in the same file, the last one overwrite others, see

--reset Reset the fishbucket for the given key or file in the btree. Resetting the checkpoint for an active monitor input reindexes data, resulting in increased license

" The data pipeline segments in depth. INPUT - In the input segment, Splunk software consumes data. It acquires the raw data stream from its source, breaks it into 64K blocks, and annotates each block with some metadata keys. The keys can also include values that are used internally, such as the character encoding of the data stream, and values that control later processing of the data, such as the index into which the events should be stored. PARSING Annotating individual events with metadata copied from the source-wide keys. Transforming event data and metadata according to regex transform rules. "

The HTTP Event Collector (HEC) supports indexer acknowledgment to confirm event delivery. Each acknowledgment is associated with a uniqueGUID(Globally Unique Identifier).

GUID ensures events are not re-indexed in the case of retries.

Incorrect Options:

B, C, D:These are not valid channel values in HEC acknowledgments.

In Splunk Enterprise, when you configure the server.conf file with strict pool quota=false, it means that license pools are allowed to share the total available license quota rather than being restricted to their individually allocated quotas. However, this does not prevent pools from issuing warnings if they exceed their allocated limits.

Given the environment with a 1000 GB/day license split into three pools:

Pool X: 500 GB/day license, 100 GB used

Pool Y: 350 GB/day license, 400 GB used

Pool Z: 150 GB/day license, 300 GB used

Let ' s analyze the usage:

Pool X is allocated 500 GB/day but has only used 100 GB, well within its limit.

Pool Y is allocated 350 GB/day but has used 400 GB, which exceeds its limit by 50 GB.

Pool Z is allocated 150 GB/day but has used 300 GB, which exceeds its limit by 150 GB.

Even with strict pool quota=false, pools Y and Z have exceeded their individual allocated quotas and will issue warnings. Pool X has not exceeded its quota and thus will not issue any warnings. Therefore, the pools that are issued warnings are Y and Z.

A Splunk deployment server is a system that distributes apps, configurations, and other assets to groups of Splunk Enterprise instances. You can use it to distribute updates to most types of Splunk Enterprise components: forwarders, non-clustered indexers, and search heads2.

A Splunk deployment server is available on every full Splunk Enterprise instance. To use it, you must activate it by placing at least one app into %SPLUNK_HOME%\etc\deployment-apps on the host you want to act as deployment server3.

A Splunk deployment server maintains the list of server classes and uses those server classes to determine what content to distribute to each client. A server class is a group of deployment clients that share one or more defined characteristics1.

A Splunk deployment client is a Splunk instance remotely configured by a deployment server. Deployment clients can be universal forwarders, heavy forwarders, indexers, or search heads. Each deployment client belongs to one or more server classes1.

A Splunk deployment app is a set of content (including configuration files) maintained on the deployment server and deployed as a unit to clients of a server class. A deployment app can be an existing Splunk Enterprise app or one developed solely to group some content for deployment purposes1.

Therefore, option C is correct, and the other options are incorrect.

Scripted Authentication: An option for Splunk Enterprise authentication. You can use an authentication system that you have in place (such as PAM or RADIUS) by configuring authentication.conf to use a script instead of using LDAP or Splunk Enterprise default authentication.

The outputs.conf file defines how forwarders send data to receivers1. You can specify some output configurations at installation time (Windows universal forwarders only) or the CLI, but most advanced configuration settings require that you edit outputs.conf1.

The [tcpout:…] stanza specifies a group of forwarding targets that receive data over TCP2. You can define multiple groups with different names and settings2.

The server setting lists one or more receiving hosts for the group, separated by commas2. If you specify multiple hosts, the forwarder load balances the data across them2.

Therefore, option A is correct, because the forwarder will send data to both inputsl.mysplunkhfs.corp:9997 and inputs2.mysplunkhfs.corp:9997, even if 145.188.183.184:9097 is unreachable.

[tcp:// < remote server > : < port > ]

*Configures the input to listen on a specific TCP network port.

*If a < remote server > makes a connection to this instance, the input uses this stanza to configure itself.

*If you do not specify < remote server > , this stanza matches all connections on the specified port.

*Generates events with source set to " tcp: < port > " , for example: tcp:514

*If you do not specify a sourcetype, generates events with sourcetype set to " tcp-raw "

When a user is assignedmultiple rolesin Splunk and each has a defined srchFilter, Splunk combines these filters using alogical ANDoperation. This ensures that the user can only search within the intersection of constraints imposed by each role.

From Splunk Docs:

" If a user has multiple roles assigned and multiple roles specify srchFilter, Splunk softwareANDs the filters together. "

— Source: Splunk Documentation – authorize.conf

Let’s break it down:

role_A specifies: sourcetype!=json AND index=main

role_B specifies: sourcetype=csv

To evaluate the effective search filter for the user, Splunk willANDthe two conditions:

(sourcetype=csv) AND (sourcetype!=json AND index=main)

This means the user ' s search is limited to events where:

sourcetype=csv (from role_B)

sourcetype!=json AND index=main (from role_A)

Combining them together logically:

srchFilter = ((sourcetype=csv) AND (sourcetype!=json AND index=main))

This is exactly what is shown inOption A.

" The forwarder/indexer relationship can be considered platform agnostic (within the sphere of supported platforms) because they exchange their data handshake (and the data, if you wish) over TCP.

Search-time field extractions are the process of extracting fields from events after they are indexed. Search-time field extractions are specified on the search head, which is the Splunk component that handles searching and reporting. Search-time field extractions are configured in props.conf and transforms.conf files, which are located in the etc/system/local directory on the search head. Therefore, option D is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [About fields - Splunk Documentation]

Splunk checks role-to-group mapping only during user login for external authentication (e.g., LDAP, SAML). Users already logged in will continue using their previously assigned roles until they log out and log back in.

The changes to role mapping do not disrupt ongoing sessions.

Incorrect Options:

B:Search is not disabled upon role updates.

C:This is incorrect since existing users are also updated upon the next login.

D:Role updates do not terminate ongoing sessions.

Data integrity controls in Splunk ensure that indexed data has not been tampered with.

When enabled, Splunk calculates hashes for each bucket and stores these hash files in the rawdata directory of the corresponding bucket.

Incorrect Options:

A, C, D:These directories do not store hash files.

The deployer is a Splunk Enterprise instance that you use to distribute apps and certain other configuration updates to search head cluster members. The set of updates that the deployer distributes is called the configuration

First line says it all: " The deployment server distributes deployment apps to clients. "

" You can specify a SEDCMD configuration in props.conf to address data that contains characters that the third-party server cannot process. "

REGEX = < regular expression >

* Enter a regular expression to operate on your data.

FORMAT = < string >

* NOTE: This option is valid for both index-time and search-time field extraction. Index-time field extraction configuration require the FORMAT settings. The FORMAT settings is optional for search-time field extraction configurations.

* This setting specifies the format of the event, including any field names or values you want to add.

DEST_KEY = < key >

* NOTE: This setting is only valid for index-time field extractions.

* Specifies where SPLUNK software stores the expanded FORMAT results in accordance with the REGEX match.

Add your data to Splunk Enterprise. With Splunk Enterprise, you can add data using Splunk Web or Splunk Apps. In addition to these methods, you also can use the following methods. -The Splunk Command Line Interface (CLI) -The inputs.conf configuration file. When you specify your inputs with Splunk Web or the CLI, the details are saved in a configuartion file on Splunk Enterprise indexer and heavy forwarder instances.

A Splunk Deployment Server is used to centrally manage and distribute apps, configurations, and updates to deployment clients. On the deployment server, the default location for deployment apps is:

$SPLUNK_HOME/etc/deployment-apps/

Apps placed in this directory can be assigned to server classes and deployed to deployment clients.

Important distinction:

$SPLUNK_HOME/etc/deployment-apps/

is used on the deployment server.

$SPLUNK_HOME/etc/apps/

is where apps are normally installed on a Splunk instance, including deployment clients after apps are received.

manager-apps and peer-apps are not the default Deployment Server app staging directory.

 The eval command is a distributable streaming command, which means that it can run on the search peers in a distributed environment1. The search peers are the indexers that store the data and perform the initial steps of the search processing2. The eval command calculates an expression and puts the resulting value into a search results field1. In your search, you are using the eval command to create a new field called “responsible_team” based on the values in the “account” field.

In Splunk Enterprise , when knowledge bundles (which include lookup files, configurations, and other knowledge objects) are replicated between search heads and indexers, administrators can control the maximum size of lookup files that are eligible for replication.

The correct parameter to use is excludeReplicatedLookupSize , defined in distsearch.conf . This parameter specifies a maximum file size (in megabytes) beyond which lookup files are excluded from bundle replication . By setting this to 500, any lookup file larger than 500 MB will not be replicated to search peers.

This is especially important for performance optimization and preventing unnecessary network load during search head to indexer communication.

Example configuration (distsearch.conf):

[replicationSettings]

excludeReplicatedLookupSize = 500

Reference (Splunk Documentation):

distsearch.conf.spec and example → excludeReplicatedLookupSize

Splunk® Enterprise Distributed Search Manual → “Control knowledge bundle replication between search heads and indexers”

Splunk Admin Manual → “Prevent large lookup files from being replicated”

According to the Splunk documentation1, a heavy forwarder is a Splunk Enterprise instance that can parse and filter data before forwarding it to an indexer. A heavy forwarder can perform line breaking,which is the process of splitting incoming data into individual events based on a set of rules2. A heavy forwarder can also apply other transformations to the data, such as field extractions, event type matching, or masking sensitive data3.

Attribute : SHOULD_LINEMERGE = [true|false]

Description : When set to true, the Splunk platform combines several input lines into a single event, with configuration based on the settings described in the next section.

To remove a search peer from a search head in a distributed search environment using the CLI, Splunk provides the splunk remove search-server command. This command is executed on the search head and removes the specified search peer from its configuration.

The correct syntax for this command is:

splunk remove search-server -auth < user > : < password > < host > : < port >

Where:

< user > : < password > are the credentials for the search head.

< host > : < port > specifies the management port of the search peer to be removed.

For example:

bash

CopyEdit

splunk remove search-server -auth admin:password 123.45.67.89:8089

This command removes the search peer from the search head ' s configuration. It ' s important to note that this action does not affect the search peer itself; it merely removes the association from the search head.
