Which of the following will cause the greatest reduction in disk size requirements for a cluster of N
indexers running Splunk Enterprise Security?
C
Explanation:
Decreasing the data model acceleration range will reduce the disk size requirements for a cluster of
indexers running Splunk Enterprise Security. Data model acceleration creates tsidx files that consume
disk space on the indexers. Reducing the acceleration range will limit the amount of data that is
accelerated and thus save disk space. Setting the cluster search factor or replication factor to N-1 will
not reduce the disk size requirements, but rather increase the risk of data loss. Increasing the
number of buckets per index will also increase the disk size requirements, as each bucket has a
minimum size. For more information, see
Data model acceleration
and
Bucket size
in the Splunk
documentation.
Stakeholders have identified high availability for searchable data as their top priority. Which of the
following best addresses this requirement?
A
Explanation:
Increasing the search factor in the cluster will best address the requirement of high availability for
searchable data. The search factor determines how many copies of searchable data are maintained
by the cluster. A higher search factor means that more indexers can serve the data in case of a failure
or a maintenance event. Increasing the replication factor will improve the availability of raw data,
but not searchable data. Increasing the number of search heads or CPUs on the indexers will improve
the search performance, but not the availability of searchable data. For more information,
see
Replication factor and search factor
in the Splunk documentation.
Search dashboards in the Monitoring Console indicate that the distributed deployment is
approaching its capacity. Which of the following options will provide the most search performance
improvement?
D
Explanation:
Adding more search peers and making sure forwarders distribute data evenly across all indexers will
provide the most search performance improvement when the distributed deployment is approaching
its capacity. Adding more search peers will increase the search concurrency and reduce the load on
each indexer. Distributing data evenly across all indexers will ensure that the search workload is
balanced and no indexer becomes a bottleneck. Replacing the indexer storage to SSD will improve
the search performance, but it is a costly and time-consuming option. Adding more search heads will
not improve the search performance if the indexers are the bottleneck. Rescheduling slow searches
to run during an off-peak time will reduce the search contention, but it will not improve the search
performance for each individual search. For more information, see [Scale your indexer cluster] and
[Distribute data across your indexers] in the Splunk documentation.
A Splunk architect has inherited the Splunk deployment at Buttercup Games and end users are
complaining that the events are inconsistently formatted for a web source. Further investigation
reveals that not all weblogs flow through the same infrastructure: some of the data goes through
heavy forwarders and some of the forwarders are managed by another department.
Which of the following items might be the cause of this issue?
C
Explanation:
The indexers may have different configurations than the heavy forwarders, which might cause the
issue of inconsistently formatted events for a web sourcetype. The heavy forwarders perform parsing
and indexing on the data before sending it to the indexers. If the indexers have different
configurations than the heavy forwarders, such as different props.conf or transforms.conf settings,
the data may be parsed or indexed differently on the indexers, resulting in inconsistent events. The
search head configurations do not affect the event formatting, as the search head does not parse or
index the data. The data inputs configurations on the forwarders do not affect the event formatting,
as the data inputs only determine what data to collect and how to monitor it. The forwarder version
does not affect the event formatting, as long as the forwarder is compatible with the indexer. For
more information, see [Heavy forwarder versus indexer] and [Configure event processing] in the
Splunk documentation.
A customer has installed a 500GB Enterprise license. They also purchased and installed a 300GB, no
enforcement license on the same license master. How much data can the customer ingest before the
search is locked out?
D
Explanation:
Search is not locked out when a customer has installed a 500GB Enterprise license and a 300GB, no
enforcement license on the same license master. The no enforcement license allows the customer to
exceed the license quota without locking search, but violations are still recorded. The customer can
ingest up to 800GB of data per day without violating the license, but if they ingest more than that,
they will incur a violation. However, the violation will not lock search, as the no enforcement license
overrides the enforcement policy of the Enterprise license. For more information, see [No
enforcement licenses] and [License violations] in the Splunk documentation.
What does the deployer do in a Search Head Cluster (SHC)? (Select all that apply.)
A, C
Explanation:
The deployer distributes apps and non-search related and manual configuration file changes to the
search head cluster members. The deployer does not bootstrap a clean Splunk install for a search
head cluster, as this is done by the captain. The deployer also does not distribute runtime knowledge
object changes made by users across the search head cluster, as this is done by the replication factor.
For more information, see
Use the deployer to distribute apps and configuration updates
in the
Splunk documentation.
When using the props.conf LINE_BREAKER attribute to delimit multi-line events, the
SHOULD_LINEMERGE attribute should be set to what?
D
Explanation:
When using the props.conf LINE_BREAKER attribute to delimit multi-line events, the
SHOULD_LINEMERGE attribute should be set to false. This tells Splunk not to merge events that have
been broken by the LINE_BREAKER. Setting the SHOULD_LINEMERGE attribute to true, auto, or none
will cause Splunk to ignore the LINE_BREAKER and merge events based on other criteria. For more
information, see
Configure event line breaking
in the Splunk documentation.
Which of the following should be included in a deployment plan?
A, B, C
Explanation:
A deployment plan should include business continuity and disaster recovery plans, current logging
details and data source inventory, and current and future topology diagrams of the IT environment.
These elements are essential for planning, designing, and implementing a Splunk deployment that
meets the business and technical requirements. A comprehensive list of stakeholders, either direct
or indirect, is not part of the deployment plan, but rather part of the project charter. For more
information, see
Deployment planning
in the Splunk documentation.
A multi-site indexer cluster can be configured using which of the following? (Select all that apply.)
B, C
Explanation:
A multi-site indexer cluster can be configured by directly editing
SPLUNK_HOME/etc/system/local/server.conf or running a splunk edit cluster-config command from
the CLI. These methods allow the administrator to specify the site attribute for each indexer node
and the site_replication_factor and site_search_factor for the cluster. Configuring a multi-site indexer
cluster via Splunk Web or directly editing SPLUNK_HOME/etc/system/default/server.conf are not
supported methods. For more information, see
Configure the indexer cluster with server.conf
in the
Splunk documentation.
Which index-time props.conf attributes impact indexing performance? (Select all that apply.)
B, D
Explanation:
The index-time props.conf attributes that impact indexing performance are LINE_BREAKER and
SHOULD_LINEMERGE. These attributes determine how Splunk breaks the incoming data into events
and whether it merges multiple events into one. These operations can affect the indexing speed and
the disk space consumption. The REPORT attribute does not impact indexing performance, as it is
used to apply transforms at search time. The ANNOTATE_PUNCT attribute does not impact indexing
performance, as it is used to add punctuation metadata to events at search time. For more
information, see [About props.conf and transforms.conf] in the Splunk documentation.
Which of the following are client filters available in serverclass.conf? (Select all that apply.)
A, B, D
Explanation:
The client filters available in serverclass.conf are DNS name, IP address, and platform (machine type).
These filters allow the administrator to specify which forwarders belong to a server class and receive
the apps and configurations from the deployment server. The Splunk server role is not a valid client
filter in serverclass.conf, as it is not a property of the forwarder. For more information, see [Use
forwarder management filters] in the Splunk documentation.
What log file would you search to verify if you suspect there is a problem interpreting a regular
expression in a monitor stanza?
D
Explanation:
The tailing_processor.log file would be the best place to search if you suspect there is a problem
interpreting a regular expression in a monitor stanza. This log file contains information about how
Splunk monitors files and directories, including any errors or warnings related to parsing the monitor
stanza. The splunkd.log file contains general information about the Splunk daemon, but it may not
have the specific details about the monitor stanza. The btool.log file contains information about the
configuration files, but it does not log the runtime behavior of the monitor stanza. The metrics.log
file contains information about the performance metrics of Splunk, but it does not log the event
breaking issues. For more information, see
About Splunk Enterprise logging
in the Splunk
documentation.
Which Splunk tool offers a health check for administrators to evaluate the health of their Splunk
deployment?
D
Explanation:
The Monitoring Console is the Splunk tool that offers a health check for administrators to evaluate
the health of their Splunk deployment. The Monitoring Console provides dashboards and alerts that
show the status and performance of various Splunk components, such as indexers, search heads,
forwarders, license usage, and search activity. The Monitoring Console can also run health checks on
the deployment and identify any issues or recommendations. The btool is a command-line tool that
shows the effective settings of the configuration files, but it does not offer a health check. The
DiagGen is a tool that generates diagnostic snapshots of the Splunk environment, but it does not
offer a health check. The SPL Clinic is a tool that analyzes and optimizes SPL queries, but it does not
offer a health check. For more information, see
About the Monitoring Console
in the Splunk
documentation.
In a four site indexer cluster, which configuration stores two searchable copies at the origin site, one
searchable copy at site2, and a total of four searchable copies?
B
Explanation:
In a four site indexer cluster, the configuration that stores two searchable copies at the origin site,
one searchable copy at site2, and a total of four searchable copies is site_search_factor = origin:2,
site2:1, total:4. This configuration tells the cluster to maintain two copies of searchable data at the
site where the data originates, one copy of searchable data at site2, and a total of four copies of
searchable data across all sites. The site_search_factor determines how many copies of searchable
data are maintained by the cluster for each site. The site_replication_factor determines how many
copies of raw data are maintained by the cluster for each site. For more information, see
Configure
multisite indexer clusters with server.conf
in the Splunk documentation.
Which of the following is true regarding Splunk Enterprise's performance? (Select all that apply.)
C, D
Explanation:
The following statements are true regarding Splunk Enterprise performance:
Adding search peers increases the search throughput as search load increases. This is because adding
more search peers distributes the search workload across more indexers, which reduces the load on
each indexer and improves the search speed and concurrency.
Adding search heads provides additional CPU cores to run more concurrent searches. This is because
adding more search heads increases the number of search processes that can run in parallel, which
improves the search performance and scalability. The following statements are false regarding Splunk
Enterprise performance:
Adding search peers does not increase the maximum size of search results. The maximum size of
search results is determined by the maxresultrows setting in the limits.conf file, which is
independent of the number of search peers.
Adding RAM to an existing search head does not provide additional search capacity. The search
capacity of a search head is determined by the number of CPU cores, not the amount of RAM.
Adding RAM to a search head may improve the search performance, but not the search capacity. For
more information, see
Splunk Enterprise performance
in the Splunk documentation.
