Quick Answer
The correct first step is to check if the forwarder is configured to send data to the correct indexer. This is the most common cause of the "No results found" error during onboarding because the universal forwarder relies on the outputs.conf file to specify the destination indexer’s IP address or hostname and the receiving port, typically 9997 for TCP output. If this configuration is wrong, the forwarder may send data to the wrong destination or nowhere at all, meaning the data never reaches the indexer tier for indexing and searching. On the Splunk Core Certified User SPLK-1002 exam, this question tests your understanding of the data pipeline’s first critical handoff—forwarder to indexer—and traps candidates who jump to checking search-time settings or data inputs first. Remember the mnemonic: "Outputs first, inputs last" when troubleshooting missing forwarded data.
This SPLK-1002 practice question tests your understanding of splunk basics and interface navigation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During onboarding, a new user can't find any data in Splunk. They see 'No results found' for all searches. The data is being forwarded from a universal forwarder. What should they check first?

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Check if the user has admin role
Why wrong: Permissions are important but not first step.
Check if the forwarder is configured to send to the correct indexer
Common misconfiguration.
Check if the firewall is blocking ports
Why wrong: Network issues would cause no indexing.
Check if the search is using the correct time range
Why wrong: Already tried all time ranges.

Correct answer & explanation
Check if the forwarder is configured to send to the correct indexer
Option B is correct because the most common reason a universal forwarder sends data that never appears in Splunk is misconfiguration of the outputs.conf file. The forwarder must specify the correct indexer IP address or hostname and the receiving port (default 9997) using the TCP output stanza; if this is wrong, data is sent to the wrong destination or nowhere at all. Checking the forwarder's configuration first isolates whether data is even reaching the indexer tier before investigating other potential issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often jump to network-level issues (firewall) or user permissions first, but Splunk's onboarding flow requires verifying the forwarder-to-indexer data path as the initial troubleshooting step, since without correct output configuration, no data can ever reach the indexer.
Detailed technical explanation
Under the hood, a universal forwarder uses outputs.conf to define one or more [tcpout:<target_group>] stanzas, each pointing to a server:port combination (e.g., 192.168.1.100:9997). If this stanza is missing or points to a non-existent indexer, the forwarder's splunkd process will log errors like 'No DNS entry for <hostname>' or 'Connection refused', but the data never leaves the forwarder. A real-world scenario is when a forwarder is configured with a load balancer VIP that is down, causing all forwarded data to be dropped silently until the network path is restored.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
