课程介绍

The CompTIA Storage+ Powered by SNIA Certification is a vendor-neutral credential.While there is no prerequisite requirement, CompTIA recommends that the Storage+ certification is intended to follow one of the CompTIA foundational level exams A+,Network+, or Server+.

This exam will certify that the successful candidate has the knowledge and skills required to configure basic networks to include archive, backup, and restoration technologies.Additionally, the successful candidate will be able to understand the fundamentals of business continuity, application workload, system integration, and storage/system administration, while performing basic troubleshooting on connectivity issues and referencing documentation.
