The entire exam structure is based on five domains. Each of them is focused on a particular skill area and tries to check the test-taker’s knowledge about it using multiple sub-domains that are observed below:
- Backup, Archive, and Replication (24%)
The final part of the exam content is all about major fault tolerance techniques and the measurements for information availability. By the end of this domain, test-takers should be able to explain what is the backup granularity and backup targets and key methods. In addition, the knowledge of the ways for data deduplication and essential data archiving solutions architecture is also well-covered in this domain. Replication uses and migration techniques are the other topics that are not left behind.
- Security and Management (16%)
The focus of this module is on concepts like information security goals, terminologies, threats to storage infrastructure, and multiple security domains. This section also tries to explain the key security controls used for storage infrastructure protection and essential infrastructure management processes and functions.
- Storage Networking Technologies (20%)
A wide-spread awareness of storage networking technologies is what a Dell DEA-1TT4 aspirant should demonstrate within the second exam domain. This involves the understanding of the FC topologies, SAN (Storage Area Network), and FC architecture. What all it takes to perform virtualization and zoning in FC SAN and ways to explain TCP/IP along with IP SAN, and iSCSI protocol are also the areas assessed in this section. Finally, one has to learn more about elements as well as connectivities of FCoE and FCIP.
- Storage Systems (26%)
This exam domain is dedicated to the skills required for storage system management. Examinees have to be able to state how to implement NAS file sharing methods, what are the components of an intelligent storage system, methods for data access, the elements of the storage system of the block-based type, and more. Besides, thorough learning about RAID and storage provisioning as well as unified storage architecture, among other topics, is also required in this section.
- Modern Data Center Infrastructure (15%)
The information covered in this domain is all about how to classify data in a data center. The candidates should be able to define core characteristics and elements of a data center along with the relevant technologies used to drive the digital transformation.
Attention also has to be given to big data, IoT, machine learning, and AI technologies. All the crucial cognizance about building a modern data center, available options for this process, storage, and connectivity is included here as well.
