SPLK-1003 Transactions and Event Correlation Practice Question
This SPLK-1003 practice question tests your understanding of transactions and event correlation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 administrator at a company with 500 employees needs to correlate VPN login events with subsequent network access logs to track user sessions. The VPN logs contain fields: user, src_ip, timestamp, event_type (login or logout). The network logs contain fields: user, dst_ip, timestamp, action (allow or deny). Both logs are indexed daily. The administrator wants to create a search that groups each VPN login with all network access events from that user within the next 8 hours. However, the current search using `transaction user startswith="login" endswith="logout" maxspan=8h` is returning many incomplete transactions where the logout event is missing. What is the most efficient way to improve the correlation without missing sessions?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use `transaction user startswith="login" endswith="logout" maxspan=8h keepevicted=true`.
Option B is correct because adding keepevicted=true will output incomplete transactions (those missing the logout event) as evicted transactions, allowing the analyst to see all sessions, including those where the logout was not recorded. Option A (maxevents=100) may still miss sessions if they don't have a logout. Option C (stats with bucket) does not properly group events into sessions. Option D (removing startswith/endswith) would group all events of the same user within 8 hours, potentially merging separate sessions inaccurately.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use a different approach: `... | stats values(*) as * by user, time_bucket | ...` with bucket times.
Why it's wrong here
Incorrect: stats does not preserve event sequence or properly group sessions.
✗
Change to `transaction user maxspan=8h` and remove startswith/endswith.
Why it's wrong here
Incorrect: Removing boundaries would group all events of that user within 8h, merging sessions and losing login/logout context.
✓
Use `transaction user startswith="login" endswith="logout" maxspan=8h keepevicted=true`.
Why this is correct
Correct: keepevicted=true outputs incomplete transactions, including those missing logout.
Related concept
Standard ACLs match source addresses.
✗
Use `transaction user maxspan=8h maxevents=100` and filter manually.
Why it's wrong here
Incorrect: maxevents=100 doesn't solve missing logout; incomplete sessions still not captured.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SPLK-1003 ACL questions on filtering logic and placement.
