This SPLK-1003 practice question tests your understanding of transactions and event correlation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A Splunk admin is troubleshooting a transaction that groups firewall allow and deny events by session ID. The transaction should end when a deny event occurs for that session. Which transaction option should be used to define the end condition?
endswith="action=allow"
Why wrong: Incorrect: This would end on allow, which is opposite of the requirement.
startswith="action=deny"
Why wrong: Incorrect: This defines the start condition, not the end.
endswith="action=deny"
Correct: This ends the transaction when a deny event is encountered.
maxevents=2
Why wrong: Incorrect: This limits the number of events per transaction, not the end condition.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
endswith="action=deny"
Option C is correct because 'endswith='action=deny'' specifies the event that terminates the transaction. Option A starts with deny, Option B ends with allow, and Option D limits the number of events but does not define an end condition.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
endswith="action=allow"
Why it's wrong here
Incorrect: This would end on allow, which is opposite of the requirement.
startswith="action=deny"
Why it's wrong here
Incorrect: This defines the start condition, not the end.
endswith="action=deny"
Why this is correct
Correct: This ends the transaction when a deny event is encountered.
Related concept
Static NAT maps one inside address to one outside address.
maxevents=2
Why it's wrong here
Incorrect: This limits the number of events per transaction, not the end condition.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SPLK-1003 NAT questions on configuration and troubleshooting.
