  https://docs.splunk.com/Documentation/Splunk/latest/Data/Configureeventlinebreaking 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.

• Question 132:

  When using license pools, volume allocations apply to which Splunk components?

  A. Indexers
  B. Indexes
  C. Heavy Forwarders
  D. Search Heads
  A. Indexers

  ---

  Explanation/Reference:

  When using license pools, volume allocations apply to indexers. A license pool is a group of indexers that share a certain amount of daily indexing volume. The license pool specifies how much data each indexer can index per day, as well as which indexes are available for each indexer. Therefore, option A is the correct answer.

• Question 133:

  Windows can prevent a Splunk forwarder from reading open files. If files need to be read while they are being written to, what type of input stanza needs to be created?

  A. Tail Reader
  B. Upload
  C. MonitorNoHandIe
  D. Monitor
  C. MonitorNoHandIe

  ---

  Explanation/Reference:

  The correct answer is C. MonitorNoHandle. MonitorNoHandle is a type of input stanza that allows a Splunk forwarder to read files on Windows systems as Windows writes to them.It does this by using a kernel-mode filter driver to capture raw

  data as it gets written to the file1.This input stanza is useful for files that get locked open for writing, such as the Windows DNS server log file2.

  The other options are incorrect because:

  A. Tail Reader is not a valid input stanza in Splunk.It is a component of the Tailing Processor, which is responsible for monitoring files and directories for new data3. B. Upload is a type of input stanza that allows Splunk to index a single file from a local or network file system.It is not suitable for files that are constantly being updated, as it only indexes the file once and does not monitor it for changes4. D. Monitor is a type of input stanza that allows Splunk to monitor files and directories for new data. However, it may not work for files that Windows prevents Splunk from reading while they are open.In such cases, MonitorNoHandle is a better option2.

  A Splunk forwarder is a lightweight agent that can forward data to a Splunk deployment. There are two types of forwarders: universal and heavy.A universal forwarder can only forward data, while a heavy forwarder can also perform parsing,

  filtering, routing, and aggregation on the data before forwarding it5. An input stanza is a section in the inputs.conf configuration file that defines the settings for a specific type of input, such as files, directories, network ports, scripts, or

  Windows event logs. An input stanza starts with a square bracket, followed by the input type and the input path or name. For example, [monitor:///var/log] is an input stanza for monitoring the /var/log directory.

• Question 134:

  The volume of data from collecting log files from 50 Linux servers and 200 Windows servers will require multiple indexers. Following best practices, which types of Splunk component instances are needed?

  A. Indexers, search head, universal forwarders, license master
  B. Indexers, search head, deployment server, universal forwarders
  C. Indexers, search head, deployment server, license master, universal forwarder
  D. Indexers, search head, deployment server, license master, universal forwarder, heavy forwarder
  C. Indexers, search head, deployment server, license master, universal forwarder

  ---

  Explanation/Reference:

  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.

• Question 135:

  Which file will be matched for the following monitor stanza in inputs. conf?

  [monitor: ///var/log/*/bar/*. txt]

  A. /var/log/host_460352847/temp/bar/file/csv/foo.txt
  B. /var/log/host_460352847/bar/foo.txt
  C. /var/log/host_460352847/bar/file/foo.txt
  D. /var/ log/ host_460352847/temp/bar/file/foo.txt
  C. /var/log/host_460352847/bar/file/foo.txt

  ---

  Explanation/Reference:

  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://]

  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.

• Question 136:

  The universal forwarder has which capabilities when sending data? (select all that apply) A. Sending alerts

  B. Compressing data

• Question 137:

  Which of the following methods will connect a deployment client to a deployment server? (select all that apply)

  A. Run $SPLUNK_ROME/bin/ splunk set deploy-poll : from the command line of the deployment client.
  B. Create and edit a deploymentserver . conf file in SSPLVNE{ on the deployment server.
  C. Create and edit a deploymentclient . conf file in SSPLTJNE( EOME/etc/ system/local on the deployment client.
  D. Run $SPLUNK ROME/bin/spiunk set deploy-poi i : from the command line of the deployment server.
  A. Run $SPLUNK_ROME/bin/ splunk set deploy-poll : from the command line of the deployment client.
  C. Create and edit a deploymentclient . conf file in SSPLTJNE( EOME/etc/ system/local on the deployment client.

  ---

  Explanation/Reference:

  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.

• Question 138:

  Assume a file is being monitored and the data was incorrectly indexed to an exclusive index. The index is cleaned and now the data must be reindexed. What other index must be cleaned to reset the input checkpoint information for that file?

  A. _audit
  B. _checkpoint
  C. _introspection
  D. _thefishbucket
  D. _thefishbucket

  ---

  Explanation/Reference:

  --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.

• Question 139:

  Running this search in a distributed environment:

  

  On what Splunk component does the eval command get executed?

  A. Heavy Forwarders
  B. Universal Forwarders
  C. Search peers
  D. Search heads
  C. Search peers

  ---

  Explanation/Reference:

  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.

• Question 140:

  Which of the following statements accurately describes using SSL to secure the feed from a forwarder?

  A. It does not encrypt the certificate password.
  B. SSL automatically compresses the feed by default.
  C. It requires that the forwarder be set to compressed=true.
  D. It requires that the receiver be set to compression=true.
  A. It does not encrypt the certificate password.
