Which TWO of the following are valid ways to configure inputs on a Universal Forwarder?
This is the standard method for configuring inputs.
Why this answer
Inputs can be managed via the CLI or by manually editing configuration files in the local directory.
You are troubleshooting a file input that is not being ingested. You have verified the file path. Which command-line tool can show you if the file is being tracked by the monitor input?
This displays the status of all files monitored by the instance.
Why this answer
The 'splunk list monitor' command shows the status of currently tracked files.
What is the effect of setting 'autoLBFrequency' in outputs.conf on a forwarder?
It controls the rotation frequency between available indexers.
Why this answer
This setting determines how often the forwarder evaluates its load-balancing configuration to redistribute data across multiple indexers.
Which protocol is the default used by Splunk Universal Forwarders to communicate with Indexers?
This is the proprietary, efficient protocol for forwarding.
Why this answer
Splunk uses the Splunk-to-Splunk (S2S) protocol, typically over TCP/9997.
A Universal Forwarder is failing to send data to the Indexer. The indexer shows no incoming traffic. Where is the first place you should check for errors?
This log contains the primary diagnostic information for the forwarder.
Why this answer
The splunkd.log on the forwarder contains logs regarding connectivity and data sending issues.
A Splunk administrator has configured a Deployment Server to manage forwarders. Which file on the forwarder must be configured to establish communication with the Deployment Server?
This file is required on the forwarder to identify the Deployment Server location.
Why this answer
The deploymentclient.conf file is used on the client-side to specify the Deployment Server's URI and poll interval.
A Universal Forwarder reports as 'missing' in the Deployment Server. What is the most common cause?
If the client cannot reach the DS, it cannot report in.
Why this answer
A missing forwarder usually indicates a network connectivity issue between the client and the deployment server.
You have configured a serverclass in serverclass.conf on the Deployment Server. Which action is required to ensure that the forwarders receive the new configuration?
The 'reload deploy-server' command forces the Deployment Server to push new configurations to clients.
Why this answer
After updating configuration files on the Deployment Server, you must either wait for the poll interval or trigger a reload of the deployment server configuration.
You have a Heavy Forwarder performing data routing. You need to send data to two different indexer clusters based on the sourcetype. How do you configure this?
This is the standard pattern for routing data to different destinations.
Why this answer
Data routing requires defining multiple target groups in outputs.conf and referencing them in transforms.conf.
What is the primary function of the Deployment Server?
It pushes apps and configs to forwarder clients.
Why this answer
The Deployment Server acts as a central repository for managing configurations and apps across forwarders.
An administrator needs to monitor a script output every 60 seconds. Which configuration in inputs.conf is correct for a scripted input?
This is the correct syntax for defining a scripted input with a 60-second interval.
Why this answer
The interval attribute in seconds determines how often a script is executed.
Which TWO locations are common places to check for configuration files on a Linux Splunk instance?
System-wide settings reside here.
Why this answer
Configurations reside in system/local or app/local directories.
Which TWO of the following are true about Heavy Forwarders?
Advanced routing is a key capability.
Why this answer
Heavy Forwarders can perform indexing (if enabled) and parsing, which UFs cannot.
To monitor a network port using a Universal Forwarder, which stanza should be added to inputs.conf?
This stanza defines a network listener for data input.
If you need to change the logging level of a specific component on a Universal Forwarder, which file should you edit?
This file is specifically for configuring internal Splunk log levels.
Why this answer
log-local.cfg (or log.cfg) controls the granularity of internal Splunk logging.
You have a deployment server managing 500 Universal Forwarders. You need to update a specific app for only 50 of them based on OS type. How should you organize the deployment?
Server classes are designed to group forwarders for specific app deployment.
Why this answer
Serverclass.conf allows targeting clients using filters based on machine name or other attributes.
Which of the following is a primary reason to choose a Heavy Forwarder over a Universal Forwarder?
Heavy Forwarders can perform parsing and transformations which Universal Forwarders cannot.
Why this answer
Heavy Forwarders are required when you need to parse data, mask sensitive information, or route data based on content before it reaches the indexer.
When using the 'monitor' stanza in inputs.conf, what does the 'followTail' attribute do?
This prevents reading historical logs upon initial startup.
Why this answer
followTail ensures that only new data appended to the file is ingested, ignoring existing content.
What is the consequence of having the same 'serverName' in server.conf for two different Universal Forwarders?
This creates confusion and incorrect reporting in the Monitoring Console.
Why this answer
Splunk uses the serverName to uniquely identify internal logs; duplicate names cause conflicts in the monitoring console.
You are deploying a Universal Forwarder to a Windows server that must monitor local Event Logs and send them to an Indexer. Which component is required to handle the parsing of these logs before they are forwarded?
Universal Forwarders send raw data; parsing occurs on the Indexer tier.
Why this answer
Universal Forwarders do not perform heavy parsing. They forward data as-is, and the Indexer handles the parsing.
Which THREE actions occur when a Universal Forwarder is added to a Deployment Server?
The DS identifies what the client should receive.
Why this answer
The forwarder handshakes, downloads app bundles, and restarts/reloads as configured.
An administrator needs to monitor a local text file on a Windows server and send the data to a Splunk indexer. Which component is the most efficient choice for this task?
The Universal Forwarder is lightweight and specifically optimized for data collection and forwarding.
Why this answer
The Universal Forwarder is designed for minimal resource consumption when collecting data and forwarding it to an indexer.
You need to ensure that a Universal Forwarder continues to collect data during a network outage between the forwarder and the indexer. Which feature should be enabled in outputs.conf?
Persistent queues allow data to be written to disk, preventing data loss during network interruptions.
Why this answer
Persistent queuing allows the forwarder to store data locally on disk when the receiving indexer is unreachable.
To ensure a Universal Forwarder is using the correct index, where is the 'index' attribute defined?
The index assignment occurs at the input level.
Why this answer
The index for a data source is defined in inputs.conf.
Which TWO components must be configured on a Universal Forwarder to ensure data reaches the Indexer?
Defines the destination Indexer.
Why this answer
A forwarder needs to know what to collect (inputs.conf) and where to send it (outputs.conf).
What is the purpose of the 'whitelist' and 'blacklist' attributes in a serverclass.conf file?
This provides granular control over deployment targets.
Why this answer
These attributes filter which clients receive specific deployment apps.
You are configuring a Heavy Forwarder to mask sensitive credit card information before the data reaches the indexer. Which configuration file must you modify to implement this data transformation?
transforms.conf is used to define the regular expression-based masking rules.
Why this answer
Data transformations such as routing, filtering, and masking occur on the Heavy Forwarder via transforms.conf and props.conf.
When configuring a Deployment Client, what must be defined in deploymentclient.conf?
This allows the client to phone home to the server.
Why this answer
The client must specify the URI and port of the Deployment Server.
Which THREE attributes can be used in serverclass.conf to define target clients?
Identifies clients that should receive the app.
Why this answer
Filters can be applied using hostnames, IP addresses, or machine classes.
Which TWO settings in outputs.conf are recommended for load balancing data across multiple indexers?
Controls the load balancing rotation.
Why this answer
To balance load, one must provide a list of indexers and define the autoLB frequency.
When using a Heavy Forwarder to perform data masking, which stanza in transforms.conf is used to define the replacement regex?
This defines the transformation rule applied to the data stream.
Why this answer
The REGEX and FORMAT attributes within a transforms.conf stanza are used for data masking.
You are configuring a scripted input to run a python script. Where is the best location to store this script on a Universal Forwarder?
Storing in the app directory allows for proper bundling and distribution.
Why this answer
Scripts should reside within an app directory to ensure they are handled correctly by the deployment server and permissions.
Which THREE factors can impact the performance of a Universal Forwarder?
Data throughput is limited by network capacity.
Why this answer
Performance can be impacted by network bandwidth, CPU usage from heavy parsing if misconfigured, and I/O wait on disk.
How do you restart the Splunk service on a Linux-based Universal Forwarder?
