Splunk Enterprise Certified Architect Practice Test

When should multiple search pipelines be enabled?

1. Only if disk IOPS is at 800 or better.

2. Only if there are fewer than twelve concurrent users.

3. Only if running Splunk Enterprise version 6.6 or later.

4. Only if CPU and memory resources are significantly under-utilized.

The correct answer is: Only if CPU and memory resources are significantly under-utilized.

Enabling multiple search pipelines is primarily beneficial when the CPU and memory resources are significantly under-utilized. This setup allows Splunk to efficiently manage more concurrent searches, improving performance when resource availability is not a constraint. By leveraging additional search pipelines, Splunk can optimize query execution and enhance overall throughput, particularly in scenarios where the existing resources can support the increased workload. In contrast, other conditions like disk IOPS limitations, concurrent user counts, or specific software version requirements do not directly correlate with the need for multiple search pipelines. While disk IOPS or the number of concurrent users can influence performance, they do not dictate whether multiple search pipelines should be implemented. The core principle is to maximize resource utilization, which is why under-utilized CPU and memory resources are the most relevant factor for enabling multiple search pipelines.
