Splunk Enterprise Certified Architect Practice Test

Why is RAID 10 recommended for Splunk indexing?

1. It provides high performance and redundancy.

2. It allows for cheaper storage options.

3. It simplifies data recovery processes.

4. It is the only option available.

The correct answer is: It provides high performance and redundancy.

RAID 10 is recommended for Splunk indexing primarily because it combines the benefits of high performance and redundancy. This configuration achieves both by mirroring data across multiple disks (which provides redundancy) and striping data across those mirrored sets (which enhances read and write performance). In the context of Splunk, where fast access to indexed data is crucial for search and analytics, the ability to rapidly read and write large volumes of data is essential. When data is mirrored, even if one disk fails, the data is still safe and accessible from the other mirrored disk, ensuring that the system remains reliable and minimizes downtime. Other choices do not align as closely with the specific requirements of Splunk indexers. While RAID configurations can potentially involve cost considerations or ease of recovery, these attributes don't directly address the core demands of indexing operations. RAID 10’s combination of speed and fault tolerance makes it a robust choice for Splunk’s data-heavy environment, thus firmly establishing it as the preferred choice for indexing tasks.
