SPLK-1003 Macros, Saved Searches and CIM Practice Question
This SPLK-1003 practice question tests your understanding of macros, saved searches and cim. 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.
Exhibit
Refer to the exhibit.
Macro definition:
```
define my_summary($index, $time_range) [search index=$index$ earliest=$time_range$ latest=now | stats count by sourcetype | rename count as total]
```
The macro is called as:
```
| `my_summary(main, -1h)`
```
The admin calls the macro as shown. What will be the expanded search string?

A
search index=main earliest=-1h latest=now | stats count by sourcetype | rename count as total
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
search index=main earliest=-1h latest=now | stats count by sourcetype | rename count as total
Option A is correct because macro arguments are substituted: $index$ becomes 'main', $time_range$ becomes '-1h'. The brackets define the search inside. Option B incorrectly concatenates. Option C uses single quotes. Option D swaps order.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
search index=main earliest=-1h latest=now | stats count by sourcetype | rename count as total
Static NAT maps one inside address to one outside address.
✗
search index='main' earliest='-1h' latest=now | stats count by sourcetype | rename count as total
Why it's wrong here
Quotes are not added by macro expansion; they are passed literally if included in argument.
✗
search index=-1h earliest=main latest=now | stats count by sourcetype | rename count as total
Why it's wrong here
Order of arguments is reversed; first argument maps to $index$.
✗
search index=main|earliest=-1h latest=now | stats count by sourcetype | rename count as total
Why it's wrong here
Incorrect spacing; macro expands with spaces around arguments.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
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
Got this wrong? Here's your next step.
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.

What is the correct answer to this question?
The correct answer is: search index=main earliest=-1h latest=now | stats count by sourcetype | rename count as total — Option A is correct because macro arguments are substituted: $index$ becomes 'main', $time_range$ becomes '-1h'. The brackets define the search inside. Option B incorrectly concatenates. Option C uses single quotes. Option D swaps order.
