Free and Premium Splunk SPLK-1003 Dumps Questions Answers

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.

Immediately after installation, a universal forwarder will start generating internal Splunk logs that contain information about its own operation, such as configuration changes, data inputs, and forwarding activities1. These logs are stored in the $SPLUNK_HOME/var/log/splunk directory on the universal forwarder machine1. The universal forwarder will not automatically detect any indexers in its subnet and begin routing data, as it needs to be configured with the IP address and port number of the indexer or the deployment server2. The universal forwarder will not begin reading local files on its server, as it needs to be configured with the data inputs that specify which files or directories to monitor2. The universal forwarder will not send an email to the operator that the installation process has completed, as this is not a default behavior of the universal forwarder and would require additional configuration3.

A Splunk Enterprise trial license gives you access to all the features of Splunk Enterprise for a limited period of time, usually 60 days1. After the trial period expires, you can either purchase a Splunk Enterprise license or switch to a Free license1.

A Splunk Enterprise Free license allows you to index up to 500 MB of data per day, but some features are disabled, such as authentication, distributed search, and alerting2. You can switch to a Free license at any time during the trial period or after the trial period expires1.

A Splunk Enterprise Forwarder license is used with forwarders, which are Splunk instances that forward data to other Splunk instances. A Forwarder license does not allow indexing or searching of data3. You can install a Forwarder license on any Splunk instance that you want to use as a forwarder4.

A Splunk Enterprise commercial end-user license is a license that you purchase from Splunk based on either data volume or infrastructure. This license gives you access to all the features of Splunk Enterprise within a defined limit of indexed data per day (volume-based license) or vCPU count (infrastructure license). You can purchase and install this license after the trial period expires or at any time during the trial period1.

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.

A bucket is the object that stores events inside of an index. According to the Splunk documentation1, “An index is a collection of directories, also called buckets, that contain index files. Each bucket represents a specific time range.” A bucket can be in one of several states, such as hot, warm, cold, frozen, or thawed1. Buckets are managed by indexers or clusters of indexers1.

ation/Splunk/8.2.1/Updating/Filterclients

The CLI command "Splunk add forward-server indexer:" is used to define the indexer and the listening port on forwards. The command creates this kind of entry "[tcpout-server://:]" in the outputs.conf file.

"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 Splunk platform instance that responses to search requests from a search head. The term "Search peer" is usually synonymous with the indexer role in a distributed search topology..."

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 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.

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

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 data during 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.

"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."

The correct answer is C and D. A heavy forwarder and an indexer are the Splunk components that can break a stream of syslog inputs into individual events.

A universal forwarder is a lightweight agent that can forward data to a Splunk deployment, but it does not perform any parsing or indexing on the data. A search head is a Splunk component that handles search requests and distributes them to indexers, but it does not process incoming data.

A heavy forwarder is a Splunk component that can perform parsing, filtering, routing, and aggregation on the data before forwarding it to indexers or other destinations. A heavy forwarder can break a stream of syslog inputs into individual events based on the line breaker and should linemerge settings in the inputs.conf file1.

An indexer is a Splunk component that stores and indexes data, making it searchable. An indexer can also break a stream of syslog inputs into individual events based on the props.conf file settings, such as TIME_FORMAT, MAX_TIMESTAMP_LOOKAHEAD, and line_breaker2.

A Splunk component is a software process that performs a specific function in a Splunk deployment, such as data collection, data processing, data storage, data search, or data visualization.

Syslog is a standard protocol for logging messages from network devices, such as routers, switches, firewalls, or servers. Syslog messages are typically sent over UDP or TCP to a central syslog server or a Splunk instance.

Breaking a stream of syslog inputs into individual events means separating the data into discrete records that can be indexed and searched by Splunk. Each event should have a timestamp, a host, a source, and a sourcetype, which are the default fields that Splunk assigns to the data.

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.

"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."

This is the endpoint URI used to collect data using the 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 endpoint URI consists of the protocol (http or https), the hostname or IP address of the Splunk server, the port number (default is 8088), and the service name (services/collector). For example:

 [monitor::/opt/log/crashlog/Jan27crash.txt]. This stanza means that Splunk is monitoring a single local file named Jan27crash.txt in the /opt/log/crashlog/ directory1. The monitor input type is used to monitor files and directories for changes and index any new data that is added2.

--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 use. 1.1/Troubleshooting/CommandlinetoolsforusewithSupport

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.

Quoting the following Splunk URL reference "Monitoring Console setup prerequisites. Forward internal logs (both $SPLUNK_HOME/car/log/splunk and $SPLUNK_HOME/var/log/introspection) to indexers from all other components. Without this step, many dashboards will lack data."

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

When Splunk is integrated with LDAP, most of the user attributes are managed by the LDAP server and cannot be changed in the Splunk UI. However, one exception is the default app attribute, which specifies which app a user sees when they log in to Splunk. This attribute can be changed in the Splunk UI by editing the user settings. Therefore, option A is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [Configure Splunk to use LDAP and map groups - Splunk Documentation]

"The HTTP Event Collector (HEC) lets you send data and application events to a Splunk deployment over the HTTP and Secure HTTP (HTTPS) protocols. HEC uses a token-based authentication model. You can generate a token and then configure a logging library or HTTP client with the token to send data to HEC in a specific format. This process eliminates the need for a Splunk forwarder when you send application events."

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.

The coldPath parameter defines the path for the cold buckets, which are the oldest and least frequently accessed data in an index1. By setting the coldPath to point to the NAS mount point, the Splunk administrator can achieve the retention strategy of having older data on slower NAS storage.

# 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

"When you use forwarder management to create a new server class, it saves the server class definition in a copy of serverclass.conf under $SPLUNK_HOME/etc/system/local. If, instead of using forwarder management, you decide to directly edit serverclass.conf, it is recommended that you create the serverclass.conf file in that same directory, $SPLUNK_HOME/etc/system/local."

- Section: About channels and sending data

Sending events to HEC with indexer acknowledgment active is similar to sending them with the setting off. There is one crucial difference: when you have indexer acknowledgment turned on, you must specify a channel when you send events. The concept of a channel was introduced in HEC primarily to prevent a fast client from impeding the performance of a slow client. When you assign one channel per client, because channels are treated equally on Splunk Enterprise, one client can't affect another. You must include a matching channel identifier both when sending data to HEC in an HTTP request and when requesting acknowledgment that events contained in the request have been indexed. If you don't, you will receive the error message, "Data channel is missing." Each request that includes a token for which indexer acknowledgment has been enabled must include a channel identifier, as shown in the following example cURL statement, where represents the event data portion of the request

"All Splunk Enterprise instances functioning as management components needs access to an Enterprise license. Management components include the deployment server, the indexer cluster manager node, the search head cluster deployer, and the monitoring console."

"The deployment server is the tool for distributing configurations, apps, and content updates to groups of Splunk Enterprise instances."

"Specify how far (how many characters) into an event Splunk software should look for a timestamp." since TIME_PREFIX = ^ and timestamp is from 0-29 position, so D=30 will pick up the WHOLE timestamp correctly.

"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."

 The setting that allows the configuration of Splunk to allow events to span over more than one line is SHOULD_LINEMERGE. This setting determines whether consecutive lines from a single source should be concatenated into a single event. If SHOULD_LINEMERGE is set to true, Splunk will attempt to merge multiple lines into one event based on certain criteria, such as timestamps or regular expressions. Therefore, option A is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [Configure event line merging - Splunk Documentation]

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.

because transforms.conf is the right configuration file to state the regex expression.
