The E20-657 exam is EMC's official test for the EMC Certification credential, a certification at the Specialist level. Earning it tells employers your skills have been verified by the vendor itself, which carries real weight in hiring and promotion decisions. Within the same certification track, it sits alongside EMC Proven Professional - Isilon Specialist, so it can also serve as a stepping stone toward those credentials.

EMC divides the EMC Isilon Specialist Exam for Technical Support Engineers exam into 5 domains. The largest ones are Data Protection and Management, Installation and Configuration, Isilon Architecture — together these account for the bulk of your score, so start there. The complete domain-by-domain outline appears in the exam topics section above on this page.
