This SPLK-1003 practice question tests your understanding of advanced visualization and lookups. 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.
Which TWO settings are required in a transforms.conf stanza for a file-based lookup to work? (Select two.)
max_matches
Why wrong: Optional; limits number of matches per event.
match_type
Required to define the matching algorithm (e.g., exact, CIDR).
case_sensitive_match
Why wrong: Optional; defaults to false.
filename
Required to specify the lookup CSV file.
default_match
Why wrong: Optional; defines default value when no match found.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
match_type
Options A and C are correct because filename specifies the lookup file, and match_type specifies how to compare the source field (e.g., exact, CIDR). Options B, D, and E are optional: max_matches limits matches, default_match provides a default value, case_sensitive_match is an advanced option.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
max_matches
Why it's wrong here
Optional; limits number of matches per event.
match_type
case_sensitive_match
Why it's wrong here
Optional; defaults to false.
filename
Why this is correct
Required to specify the lookup CSV file.
Related concept
CIDR notation defines the prefix length.
default_match
Why it's wrong here
Optional; defines default value when no match found.
Common exam traps
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related SPLK-1003 subnetting questions on CIDR, address ranges, and subnet selection.
