SPLK-1003 Splunk Enterprise Certified Admin Questions and Answers

When creating new user roles in Splunk, it ' s recommended to define roles that incorporate the necessary capabilities and index access permissions. This approach allows for granular control over user access and aligns with best practices for role-based access control.

" You can create custom roles and assign those roles to your users. Custom roles let you make granular adjustments to user access, including... Role inheritance... Capabilities... Allowed and default indexes... "

— About configuring role-based user access -

By creating roles that incorporate both capabilities and index access, administrators can efficiently manage user permissions and maintain a secure Splunk environment.

In Splunk Enterprise , when integrating with an LDAP (Lightweight Directory Access Protocol) directory for authentication, user access is governed by the mapping between LDAP groups and Splunk roles . A user authenticated via LDAP must belong to at least one LDAP group that is mapped to a Splunk role. Without this mapping, the user can authenticate successfully against LDAP but will not be granted any role privileges inside Splunk, and therefore cannot log in to the Splunk web interface.

Splunk documentation explicitly states:

“When you integrate Splunk Enterprise with LDAP, a user must be assigned at least one Splunk role through an LDAP group mapping. If the user does not belong to a mapped group, they cannot log into Splunk.”

This ensures that user permissions are inherited from LDAP-to-role mappings and provides centralized management of authentication and authorization.

" 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.

- 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 < data > represents the event data portion of the request

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.

" To activate distributed search, you add search peers, or indexers, to a Splunk Enterprise instance that you desingate as a search head. You do this by specifying each search peer manually. "

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.

The correct answer is D. No, because the event time is greater than the retention time.

According to the Splunk documentation1, the frozenTimePeriodInSecs setting in indexes.conf determines how long Splunk software retains indexed data before deleting it or archiving it to a remote storage. The default value is 188697600 seconds, which is equivalent to six years. The setting can be overridden on a per-index basis.

In this case, the cat_facts index has a frozenTimePeriodInSecs setting of 2630000 seconds, which is equivalent to about 30 days. This means that any event that is older than 30 days from the current time will be removed from the index and will not be searchable.

The event timestamp was 3739283 seconds ago, which is equivalent to about 43 days. This means that the event is older than the retention time of the cat_facts index and will not be searchable.

The other settings in the stanza, such as maxHotSpanSecs and maxTota1DataSizeMB, do not affect the retention time of the events. They only affect the size and duration of the buckets that store the events.

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.

https://docs.splunk.com/Documentation/Splunk/8.1.2/Admin/Aboutlicenseviolations

" An Enterprise license stack with a license volume of 100 GB of data per day or more does not currently violate. "

IgnoreOlderThan:This setting filters files for indexing based on their age. It does not prevent indexing of old data already in the file.

allowList:This setting allows specifying patterns to include files for monitoring, but it does not control indexing of pre-existing data.

monitor:This is the default method for monitoring files but does not address indexing pre-existing data.

followTail:This attribute, when set in inputs.conf, ensures that Splunk starts reading a file from the end (tail) and does not index existing old data. It is ideal for scenarios with large files where only new updates are relevant.

The Splunk Deployment Server is a centralized component used to distribute configurations and apps to multiple deployment clients , such as forwarders, indexers, or other Splunk instances.

By default, all deployment apps that the Deployment Server manages are stored in the directory:

$SPLUNK_HOME/etc/deployment-apps/

Each subdirectory under this path represents a deployment app that can be pushed to one or more clients based on rules defined in serverclass.conf.

The Deployment Server stages updates in /etc/deployment-apps/ and deploys them to clients based on matching server classes. This mechanism allows centralized management and configuration consistency across distributed Splunk environments.

Reference (Splunk Documentation):

Splunk® Enterprise Admin Manual → Use the deployment server to deploy configurations

serverclass.conf.spec and example → “Deployment server staging area is $SPLUNK_HOME/etc/deployment-apps/.”

Splunk Docs: “About deployment server”

" 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. "

https://docs.splunk.com/Documentation/Splunk/8.1.3/Security/ConfigureLDAPwithSplunkWeb

" You can map either users or groups, but not both. If you are using groups, all users must be members of an appropriate group. Groups inherit capabilities form the highest level role they ' re a member of. " " If your LDAP environment does not have group entries, you can treat each user as its own group. "

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 < IP_address/hostname > : < management_port >  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 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.

Splunk REST API is a valid method to create a Splunk user. The Splunk REST API allows administrators to create, edit, and delete users programmatically using HTTP requests. The other options are not valid methods to create a Splunk user. Creating a support ticket does not create a user, but requests assistance from Splunk support. Creating a user on the host operating system does not create a Splunk user, but a system user. Adding the username to users.conf does not create a user, but modifies the configuration file that stores user information. References = Configure users with the CLI, Configure users and roles

 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]

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 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.

use transformations with props.conf and transforms.conf to:

– Mask or delete raw data as it is being indexed

–Override sourcetype or host based upon event values

– Route events to specific indexes based on event content

– Prevent unwanted events from being indexed

[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 "

- etc/system/local/ has better precedence at index time - for identical settings in the same file, the last one overwrite others, see :https://community.splunk.com/t5/Getting-Data-In/What-is-the-precedence-for-identical-stanzas-within-a-single/m-p/283566

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 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.

https://docs.splunk.com/Documentation/Forwarder/8.0.5/Forwarder/Configuretheuniversalforwarder

--Key configuration files are: inputs.conf controls how the forwarder collects data. outputs.conf controls how the forwarder sends data to an indexer or other forwarder server.conf for connection and performance tuning deploymentclient.conf for connecting to a deployment server

 Indexers, search head, deployment server, license master, universal forwarder. This is the combination of Splunk component instances that are needed to handle the volume of data from collecting log files from 50 Linux servers and 200 Windows servers, following the best practices. The roles and functions of these components are:

Indexers: These are the Splunk instances that index the data and make it searchable. They also perform some data processing, such as timestamp extraction, line breaking, and field extraction. Multiple indexers can be clustered together to provide high availability, data replication, and load balancing.

Search head: This is the Splunk instance that coordinates the search across the indexers and merges the results from them. It also provides the user interface for searching, reporting, and dashboarding. A search head can also be clustered with other search heads to provide high availability, scalability, and load balancing.

Deployment server: This is the Splunk instance that manages the configuration and app deployment for the universal forwarders. It allows the administrator to centrally control the inputs.conf, outputs.conf, and other configuration files for the forwarders, as well as distribute apps and updates to them.

License master: This is the Splunk instance that manages the licensing for the entire Splunk deployment. It tracks the license usage of all the Splunk instances and enforces the license limits and violations. It also allows the administrator to add, remove, or change licenses.

Universal forwarder: These are the lightweight Splunk instances that collect data from various sources and forward it to the indexers or other forwarders. They do not index or parse the data, but only perform minimal processing, such as compression and encryption. They are installed on the Linux and Windows servers that generate the log files.

The correct answer is D. Place both props . conf and transforms . conf on the Heavy Forwarder for source A, and place both props . conf and transforms . conf on the indexer for source B.

According to the Splunk documentation1, to mask sensitive data from raw events, you need to use the SEDCMD attribute in the props.conf file and the REGEX attribute in the transforms.conf file. The SEDCMD attribute applies a sed expression to the raw data before indexing, while the REGEX attribute defines a regular expression to match the data to bemasked.You need to place these files on the Splunk instance that parses the data, which isusually the indexer or the heavy forwarder2. The universal forwarder does not parse the data, so it does not need these files.

For source A, the data is routed through a heavy forwarder, which can parse the data before sending it to the indexer. Therefore, you need to place both props.conf and transforms.conf on the heavy forwarder for source A, so that the masking takes place before indexing.

For source B, the data is routed directly to the indexer, which parses and indexes the data. Therefore, you need to place both props.conf and transforms.conf on the indexer for source B, so that the masking takes place before indexing.

" 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 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.

" 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. "

https://docs.splunk.com/Documentation/Splunk/8.2.2/Updating/Aboutdeploymentserver

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

Set the stanza to have a server value equal to a comma-separated list of IP addresses and indexer ports for each of the indexers in the environment. This is explained in the Splunk documentation1, which states:

To enable automatic load balancing, set the stanza to have a server value equal to a comma-separated list of IP addresses and indexer ports for each of the indexers in the environment. For example:

[tcpout] server=10.1.1.1:9997,10.1.1.2:9997,10.1.1.3:9997

The forwarder then distributes data across all of the indexers in the list.

" 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. "

The Data Preview feature should be used when validating the parsing of data. The Data Preview feature allows you to preview how Splunk software will index your data before you commit the data to an index. You can use the Data Preview feature to check the following aspects of data parsing1:

Timestamp recognition: You can verify that Splunk software correctly identifies the timestamps of your events and assigns them to the _time field.

Event breaking: You can verify that Splunk software correctly breaks your data stream into individual events based on the line breaker and should linemerge settings.

Source type assignment: You can verify that Splunk software correctly assigns a source type to your data based on the props.conf file settings. You can also manually override the source type if needed.

Field extraction: You can verify that Splunk software correctly extracts fields from your events based on the transforms.conf file settings. You can also use the Interactive Field Extractor (IFX) to create custom field extractions.

The Data Preview feature is available in Splunk Web under Settings > Data inputs > Data preview. You can access the Data Preview feature when you add a new input or edit an existing input1.

The other options are incorrect because:

A. When extracting fields for ingested data. The Data Preview feature can be used to verify the field extraction for data that has not been ingested yet, but not for data that has already been indexed. To extract fields from ingested data, you can use the IFX or the rex command in the Search app2.

B. When previewing the data before searching. The Data Preview feature does not allow you to search the data, but only to view how it will be indexed. To preview the data before searching, you can use the Search app and specify a time range or a sample ratio.

C. When reviewing data on the source host. The Data Preview feature does not access the data on the source host, but only the data that has been uploaded or monitored by Splunk software. To review data on the source host, you can use the Splunk Universal Forwarder or the Splunk Add-on for Unix and Linux.

 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.

A role in Splunk is a classification that determines what capabilities and indexes a user has.A capability is a permission to perform a specific action or access a specific feature on the Splunk platform1.An index is a collection of data that Splunk software processes andstores2. By assigning roles to users, you can control what they can do and what data they can access on the Splunk platform.

Therefore, the correct answers are A and D. A role in Splunk determines what capabilities and indexes a user has. Option B is incorrect because Splunk servers do not use roles to remotely control each other.Option C is incorrect because Splunk servers use instances and components to determine what functions they control3.

https://docs.splunk.com/Documentation/Splunk/8.1.1/Indexer/HowSplunkstoresindexes

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.
