A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
You are choosing a replication factor for a new indexer cluster. What number does that setting fix?
Correct.
Checked against help.splunk.com, August 2026Concept
The factor is a promise about how many machines can fail before data is lost. Everything about cluster sizing follows from that number.
Why B
Splunk states that peer nodes store incoming data in buckets, that the cluster maintains multiple copies of each bucket on separate peer nodes, and that the number of copies of each bucket the cluster maintains is the replication factor.
Source
Splunk Docs: Replication factor, checked August 2026Peer nodes store incoming data in buckets, and the cluster maintains multiple copies of each bucket. The cluster stores each bucket copy on a separate peer node. The number of copies of each bucket that the cluster maintains is the replication factor.
Now you: objective 15.1 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
Your cluster must keep working through the simultaneous loss of two peer nodes. How many peer failures can a cluster tolerate?
Sample question 2 of 3
In your indexer cluster each peer indexes its own incoming data and also stores copies sent from other peers. Which roles does a single peer play?
Sample question 3 of 3
An administrator asks the default search factor. What value does Splunk give?
