Which Splunk log file would be the least helpful in troubleshooting a crash?
Answer : A
The splunk_instrumentation.log file is the least helpful in troubleshooting a crash, because it contains information about the Splunk Instrumentation feature, which collects and sends usage data to Splunk Inc. for product improvement purposes. This file does not contain any information about the Splunk processes, errors, or crashes.The other options are more helpful in troubleshooting a crash, because they contain relevant information about the Splunk daemon, the standard error output, and the crash report12

When Splunk indexes data in a non-clustered environment, what kind of files does it create by default?
Answer : A
When Splunk indexes data in a non-clustered environment, it creates index and .tsidx files by default. The index files contain the raw data that Splunk has ingested, compressed and encrypted. The .tsidx files contain the time-series index that maps the timestamps and event IDs of the raw data. The rawdata and index files are not the correct terms for the files that Splunk creates. The compressed and .tsidx files are partially correct, but compressed is not the proper name for the index files. The compressed and meta data files are also partially correct, but meta data is not the proper name for the .tsidx files.
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?
Answer : B
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.

What is the recommended order of activities in the Splunk deployment process?
Answer : A
Splunk's official planning guidance explains that the deployment cycle begins with defining the system architecture, capacity planning, platform design, and topologies. Splunk states that before any component is installed, administrators must complete ''infrastructure planning and buildout,'' which includes determining indexer capacity, search head roles, clustering strategy, storage layout, and performance requirements. This foundational step ensures that all Splunk components have the proper hardware, network design, and scaling expectations.
After the environment is built, Splunk documentation states that the next stage is ''deployment and data onboarding,'' which includes configuring indexers, forwarders, parsing rules, event processing pipelines, data source validation, and enrichment steps such as field extractions, tagging, event types, and CIM alignment. Splunk describes this as the phase where you bring in data and confirm correctness, completeness, and normalization.
Only after the system is stable and populated with data does Splunk recommend ''user planning and rollout'', which includes developing dashboards, roles, knowledge objects, search best practices, and enabling user access. Splunk emphasizes that user onboarding should occur last, once infrastructure and data pipelines are fully validated.

(Where can files be placed in a configuration bundle on a search peer that will persist after a new configuration bundle has been deployed?)
Answer : D
According to the Indexer Clustering Administration Guide, configuration bundles pushed from the Cluster Manager (Master Node) overwrite the contents of the $SPLUNK_HOME/etc/slave-apps/ directory on each search peer (indexer). However, Splunk provides a special persistent location --- the _cluster app's local directory --- for files that must survive bundle redeployments.
Specifically, any configuration files placed in:
$SPLUNK_HOME/etc/slave-apps/_cluster/local/
will persist after future bundle pushes because this directory is excluded from the automatic overwrite process.
This is particularly useful for maintaining local overrides or custom configurations that should not be replaced by the Cluster Manager, such as environment-specific inputs, temporary test settings, or monitoring configurations unique to that peer.
Other directories under slave-apps are overwritten each time a configuration bundle is pushed, ensuring consistency across the cluster. Likewise, master-apps exists only on the Cluster Manager and is used for deployment, not persistence.
Thus, the _cluster/local folder is the only safe, Splunk-documented location for configurations that need to survive bundle redeployment.

Which of the following are client filters available in serverclass.conf? (Select all that apply.)
Answer : A, B, D
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.
(A customer has a Splunk Enterprise deployment and wants to collect data from universal forwarders. What is the best step to secure log traffic?)
Answer : A
Splunk Enterprise documentation clearly states that the best method to secure log traffic between Universal Forwarders (UFs) and Indexers is to implement Transport Layer Security (TLS) using signed SSL certificates. When Universal Forwarders send data to Indexers, this communication can be encrypted using SSL/TLS to prevent eavesdropping, data tampering, or interception while in transit.
Splunk provides default self-signed certificates out of the box, but these are only for testing or lab environments and should not be used in production. Production-grade security requires custom, signed SSL certificates --- either from an internal Certificate Authority (CA) or a trusted public CA. These certificates validate both the sender (forwarder) and receiver (indexer), ensuring data integrity and authenticity.
In practice, this involves:
Generating or obtaining CA-signed certificates.
Configuring the forwarder's outputs.conf to use SSL encryption (sslCertPath, sslPassword, and sslRootCAPath).
Configuring the indexer's inputs.conf and server.conf to require and validate client certificates.
This configuration ensures end-to-end encryption for all log data transmitted from forwarders to indexers.
Routing traffic through a WAF (Option C) does not provide end-to-end encryption for Splunk's internal communication, and securing search head--to--indexer communication (Option D) is unrelated to forwarder data flow.
