Free and Premium Splunk SPLK-1003 Dumps Questions Answers

"The Splunk platform collects remote Windows data for indexing in one of two ways: From Splunk forwarders, Using Windows Management Instrumentation (WMI). For Splunk Cloud deployments, you must use the Splunk Universal Forwarder on a Windows machines to montior remote Windows data."

[tcp://:]

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

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

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

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

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

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.

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

curl \ -H “Authorization: Splunk DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67” \ -d ‘{“event”: “Hello World”}, {“event”: “Hola Mundo”}, {“event”: “Hallo Welt”}’. This is the correct curl command to send multiple events through HTTP Event Collector (HEC), which is a token-based API that allows you to send data to Splunk Enterprise from any application that can make an HTTP request. The command has the following components:

The URL of the HEC endpoint, which consists of the protocol (https), the hostname or IP address of the Splunk server (mysplunkserver.example.com), the port number (8088), and the service name (services/collector).

The header that contains the authorization token, which is a unique identifier that grants access to the HEC endpoint. The token is prefixed with Splunk and enclosed in quotation marks. The token value (DF4S7ZE4-3GS1-8SFS-E777-0284GG91PF67) is an example and should be replaced with your own token value.

The data payload that contains the events to be sent, which are JSON objects enclosed in curly braces and separated by commas. Each event object has a mandatory field called event, which contains the raw data to be indexed. The event value can be a string, a number, a boolean, an array, or another JSON object. In this case, the event values are strings that say hello in different languages.

The ellipsis wildcard searches recursively through directories and any number of levels of subdirectories to find matches.

If you specify a folder separator (for example, //var/log/.../file), it does not match the first folder level, only subfolders.

* The asterisk wildcard matches anything in that specific folder path segment.

Unlike ..., * does not recurse through subfolders.

The next step to enable the communication between the forwarder and the deployment server after installing a new forwarder with a manually created deploymentclient.conf is to restart Splunk on the deployment client. The deploymentclient.conf file contains the settings for the deployment client, which is a Splunk instance that receives updates from the deployment server. The file must include the targetUri attribute, which specifies the hostname and management port of the deployment server. To apply the changes in the deploymentclient.conf file, Splunk must be restarted on the deployment client. Therefore, option C is the correct answer.

# Compression

#

# This example sends compressed events to the remote indexer.

# NOTE: Compression can be enabled TCP or SSL outputs only.

# The receiver input port should also have compression enabled.

[tcpout]

server = splunkServer.example.com:4433

compressed = true

Scroll down to the section Titled, How to configure forwarder inputs, and subsection Here are the main ways that you can configure data inputs on a forwarder Install the app or add-on that contains the inputs you wants

The correct methods to connect a deployment client to a deployment server are A and C. You can either run the command splunk set deploy-poll : from the command line of the deployment client1 or create and edit a deploymentclient.conf file in $SPLUNK_HOME/etc/system/local on the deployment client2. Both methods require you to specify the IP address, hostname, and management port of the deployment server that you want the client to connect to.

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.

"Every Splunk instance has a fishbucket index, except the lightest of hand-tuned lightweight forwarders, and if you index a lot of files it can get quite large. As any other index, you can change the retention policy to control the size via indexes.conf"

Reference

REGEX =

* Enter a regular expression to operate on your data.

FORMAT =

* 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 =

* 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.

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.

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.

Per the provided Splunk reference URL

"While HEC has precautions in place to prevent data loss, it's impossible to completely prevent such an occurrence, especially in the event of a network failure or hardware crash. This is where indexer acknolwedgment comes in."

Scrolling down to the section titled "Define the sed script in props.conf shows the correct syntax of an example which validates that the number/character /1 immediately preceded the /g

The inputs.conf file is used to configure inputs, distributed inputs such as forwarders, and file system monitoring in Splunk1.

The [script://myscript.sh] stanza specifies a script input, which means that Splunk runs the script and indexes its output1.

The interval setting determines how often Splunk runs the script. If the interval is set to 0, the script runs only once when Splunk starts up1. If the interval is omitted, the script runs at the default interval of 60 seconds2.

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

The correct answer is C. /var/log/host_460352847/bar/file/foo.txt.

The monitor stanza in inputs.conf is used to configure Splunk to monitor files and directories for new data. The monitor stanza has the following syntax1:

[monitor://<input path>]

The input path can be a file or a directory, and it can include wildcards (*) and regular expressions. The wildcards match any number of characters, including none, while the regular expressions match patterns of characters. The input path is case-sensitive and must be enclosed in double quotes if it contains spaces1.

In this case, the input path is /var/log//bar/.txt, which means Splunk will monitor any file with the .txt extension that is located in a subdirectory named bar under the /var/log directory. The subdirectory bar can be at any level under the /var/log directory, and the * wildcard will match any characters before or after the bar and .txt parts1.

Therefore, the file /var/log/host_460352847/bar/file/foo.txt will be matched by the monitor stanza, as it meets the criteria. The other files will not be matched, because:

A. /var/log/host_460352847/temp/bar/file/csv/foo.txt has a .csv extension, not a .txt extension.

B. /var/log/host_460352847/bar/foo.txt is not located in a subdirectory under the bar directory, but directly in the bar directory.

D. /var/log/host_460352847/temp/bar/file/foo.txt is located in a subdirectory named file under the bar directory, not directly in the bar directory.

The fastest way to add data to your Splunk Cloud instance or Splunk Enterprise deployment is to use Splunk Web. After you access the Add Data page, choose one of three options for getting data into your Splunk platform deployment with Splunk Web: (1) Upload, (2) Monitor, (3) Forward The Upload option lets you upload a file or archive of files for indexing. When you choose Upload option, Splunk Web opens the upload process page. Monitor. For Splunk Enterprise installations, the Monitor option lets you monitor one or more files, directories, network streams, scripts, Event Logs (on Windows hosts only), performance metrics, or any other type of machine data that the Splunk Enterprise instance has access to.

 The parsing phase is the process of extracting fields and values from raw data. The parsing phase respects LINE_BREAKER, SHOULD_LINEMERGE, BREAK_ONLY_BEFORE_DATE, and all other line merging settings in props.conf. These settings determine how Splunk breaks the data into events based on certain criteria, such as timestamps or regular expressions. The event boundaries are defined by the props.conf file, which can be modified by the administrator. Therefore, the parsing phase is the last opportunity for defining event boundaries.

"Configure character set encoding. Splunk software attempts to apply UTF-8 encoding to your scources by default. If a source foesn't use UTF-8 encoding or is a non-ASCII file, Splunk software tries to convert data from the source to UTF-8 encoding unless you specify a character set to use by setting the CHARSET key in the props.conf file."

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.

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.

The app local directories move to second in the priority list. This is explained in the Splunk documentation, which states:

In a clustered environment, the precedence of configuration files changes slightly from that of a standalone deployment. The app local directories move to second in the priority list, after the peer-apps local directory. This means that any configuration files in the app local directories on the individual peers are overridden by configuration files of the same name and type in the peer-apps local directory on the master node.

The Splunk indexing process consists of three main phases: Input, Parsing, and Indexing. Understanding these phases is crucial for configuring data inputs and managing data flow within Splunk.

Input Phase: Splunk receives data from various sources, such as files, network ports, or scripted inputs.

Parsing Phase: Splunk breaks the data into individual events, applies transformations, and extracts timestamps.

Indexing Phase: Splunk writes the parsed events to disk and creates indexes for efficient searching.

From the official Splunk documentation:

"The data pipeline consists of three main phases: input, parsing, and indexing."

— How the Splunk platform indexes data - Splunk Documentation

Therefore, the correct order of the indexing process is: Input phase → Parsing phase → Indexing phase.

"You can group your search peers to facilitate searching on a subset of them. Groups of search peers are known as "distributed search groups." You specify distributed search groups in the distsearch.conf file"

The following items in the phases below are listed in the order Splunk applies them (ie LINE_BREAKER occurs before TRUNCATE).

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.

Adding further clarity and quoting same Splunk reference URL from @giubal"

"To keep configuration settings consistent across peer nodes, configuration files are managed from the cluster master, which pushes the files to the slave-app directories on the peer nodes. Files in the slave-app directories have the highest precedence in a cluster peer's configuration. Here is the expanded precedence order for cluster peers:

1.Slave-app local directories -- highest priority

2. System local directory

3. App local directories

4. Slave-app default directories

5. App default directories

6. System default directory --lowest priority

"The search head replicates the knowledge bundle periodically in the background or when initiating a search. " "As part of the distributed search process, the search head replicates and distributes its knowledge objects to its search peers, or indexers. Knowledge objects include saved searches, event types, and other entities used in searching accorss indexes. The search head needs to distribute this material to its search peers so that they can properly execute queries on its behalf."

"From the user standpoint, specifying and running a distributed search is essentially the same as running any other search. Behind the scenes, the search head distributes the query to its search peers, and consolidates the results when presenting them to the user."

Once further conditions are met (for example, the index reaches some maximum number of warm buckets), the indexer begins to roll the warm buckets to cold, based on their age. It always selects the oldest warm bucket to roll to cold. Buckets continue to roll to cold as they age in this manner. Cold buckets reside in a different location from hot and warm buckets. You can configure the location so that cold buckets reside on cheaper storage.

Section titled, Configuration file directories, states "A detailed list of settings for each configuration file is provided in the .spec file names for that configuration file. You can find the latest version of the .spec and .example files in the $SPLUNK_HOME/etc system/README folder of your Splunk Enterprise installation..."

The indexing pipeline and the parsing pipeline are the two pipelines that are responsible for transforming the raw data into events and preparing them for indexing. The indexing pipeline applies index-time settings, such as timestamp extraction, line breaking, host extraction, and source type recognition. The parsing pipeline applies parsing settings, such as field extraction, event segmentation, and event annotation.

Setting: ignoreOlderThan = Description: "Causes the input to stop checking files for updates if the file modification time has passed the threshold." Default: 0 (disabled)

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

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.

"To determine the order of directories for evaluating configuration file precendence, Splunk software considers each file's context. Configuration files operate in either a global context or in the context of the current app and user"

Splunk uses alayered configuration modelwhere settings are loaded in a specific order. This order determines which configuration takes precedence when multiple settings conflict. Atindex time(the point when data is parsed and indexed), the configuration precedence is clearly defined in the official documentation.

FromSplunk Docs(props.conf precedence):

Configuration file resolution order (highest to lowest precedence):

$SPLUNK_HOME/etc/users//<appname>/local

$SPLUNK_HOME/etc/apps/<appname>/local

$SPLUNK_HOME/etc/apps/<appname>/default

$SPLUNK_HOME/etc/system/local

$SPLUNK_HOME/etc/system/default

However, forindex-time configurations, a slight difference applies:

system/local and users/local areoften treated specially, butin practice and according to Splunk Docs, thesystem/localconfigs override apps/default, and so on.

InOption C, the correct precedence fromhighest to lowestis:

/etc/users/local (Highest)

/etc/system/default

/etc/apps/aaa/local

/etc/apps/zzz/default

/etc/system/local (Lowest of these listed)

Though system/local typically has high precedence,when users/local is involved, that is the ultimate override. Splunk Docs confirms this in:

Configuration file precedence

Configuration layering reference

Therefore, Option C reflects the correct Splunk configuration file precedence order at index time.

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:] stanzas. The groups present in defaultGroup in [tcpout] stanza in the outputs.conf file.

"A heavy forwarder parses data before forwarding it and can route data based on criteria such as source or type of event."

"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 correct answer is B. The network input in Splunk might be found in the $SPLUNK_HOME/etc/apps/$appName/local/inputs.conf file.

A network input is a type of input that monitors data from TCP or UDP ports. To configure a network input, you need to specify the port number, the connection host, the source, and the sourcetype in the inputs.conf file. You can also set other optional settings, such as index, queue, and host_regex1.

The inputs.conf file is a configuration file that contains the settings for different types of inputs, such as files, directories, scripts, network ports, and Windows event logs. The inputs.conf file can be located in various directories, depending on the scope and priority of the settings. The most common locations are:

$SPLUNK_HOME/etc/system/default: This directory contains the default settings for all inputs. You should not modify or copy the files in this directory2.

$SPLUNK_HOME/etc/system/local: This directory contains the custom settings for all inputs that apply to the entire Splunk instance. The settings in this directory override the default settings2.

$SPLUNK_HOME/etc/apps/$appName/default: This directory contains the default settings for all inputs that are specific to an app. You should not modify or copy the files in this directory2.

$SPLUNK_HOME/etc/apps/$appName/local: This directory contains the custom settings for all inputs that are specific to an app. The settings in this directory override the default and system settings2.

Therefore, the best practice is to create or edit the inputs.conf file in the $SPLUNK_HOME/etc/apps/$appName/local directory, where $appName is the name of the app that you want to configure the network input for. This way, you can avoid modifying the default files and ensure that your settings are applied to the specific app.

The other options are incorrect because:

A. There is no network directory under the apps directory. The network input settings should be in the inputs.conf file, not in a separate directory.

C. There is no udp.conf file in Splunk. The network input settings should be in the inputs.conf file, not in a separate file. The system directory is not the recommended location for custom settings, as it affects the entire Splunk instance.

D. The var/lib/splunk directory is where Splunk stores the indexed data, not the input settings. The homePath setting is used to specify the location of the index data, not the input data. The inputName is not a valid variable for inputs.conf.
