Why One Index Returns Events Older Than 24 Hours — maxGlobalTimeFieldSec
This SPLK-1002 practice question tests your understanding of splunk basics and interface navigation. 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.
```
[default]
maxGlobalTimeFieldSec = 3600
[sample_index]
repFactor = auto
maxGlobalTimeFieldSec = 604800
```
Refer to the exhibit. An administrator notices that searches against the 'sample_index' index return events older than 24 hours, while searches against other indexes do not. What is the most likely explanation?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Exhibit
Refer to the exhibit.
```
[default]
maxGlobalTimeFieldSec = 3600
[sample_index]
repFactor = auto
maxGlobalTimeFieldSec = 604800
```
A
The maxGlobalTimeFieldSec setting for 'sample_index' is much higher than the default.
maxGlobalTimeFieldSec limits the time window for searches; a higher value allows older events.
B
The default stanza sets a maxGlobalTimeFieldSec that applies to all indexes, but is overridden incorrectly.
Why wrong: The default stanza is overridden for sample_index, but the effect is as described.
C
The index 'sample_index' has a replication factor set that allows older data.
Why wrong: repFactor affects copy count, not time window.
D
The search time range is configured in the search itself to include older data for that index.
Why wrong: The exhibit is server config, not search time range.

Correct answer & explanation
✓
The maxGlobalTimeFieldSec setting for 'sample_index' is much higher than the default.
The `maxGlobalTimeFieldSec` setting in indexes.conf controls the maximum age (in seconds) of events that can be returned by a global search (i.e., a search without an explicit time range). If this value is set much higher than the default (which is typically 86400 seconds, or 24 hours), searches against that index will return events older than 24 hours even when no time range is specified. This explains why only 'sample_index' shows older data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
maxGlobalTimeFieldSec limits the time window for searches; a higher value allows older events.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse `maxGlobalTimeFieldSec` with the `maxTimeFieldSec` setting (which limits the maximum time range a user can search), or assume that the issue is related to search time range configuration or replication factor, rather than the index-level time constraint for global searches.
Detailed technical explanation
How to think about this question
The `maxGlobalTimeFieldSec` parameter is defined in the `[indexname]` stanza of indexes.conf and defaults to 86400 (24 hours). When a search is run without an explicit time range (i.e., a global search), Splunk uses this setting to limit the time window of events returned. If an administrator increases this value (e.g., to 604800 for 7 days), the index will return events up to that age. This is often used for indexes that contain historical data or logs that need to be accessible without requiring a time picker adjustment.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SPLK-1002 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

What is the correct answer to this question?
The correct answer is: The maxGlobalTimeFieldSec setting for 'sample_index' is much higher than the default. — The `maxGlobalTimeFieldSec` setting in indexes.conf controls the maximum age (in seconds) of events that can be returned by a global search (i.e., a search without an explicit time range). If this value is set much higher than the default (which is typically 86400 seconds, or 24 hours), searches against that index will return events older than 24 hours even when no time range is specified. This explains why only 'sample_index' shows older data.
