EMC D-ISM-FN-23 Actual Questions

Automated storage tiering is a feature of an intelligent storage system that allows data to be moved between tiers of storage based on usage patterns. This can provide better performance and cost savings by ensuring that data is stored in the most appropriate storage tier for its access patterns. For example, data that is frequently accessed can be stored in higher-performing storage tiers, while data that is infrequently accessed can be moved to lower-performing, lower-cost storage tiers.

Amazon S3 (Simple Storage Service) is a cloud-based file sharing protocol that provides file sharing through a REST API interface. S3 allows users to store and retrieve any amount of data at any time, using a simple web interface. It is widely used for cloud storage and integrates seamlessly with various applications and services.References:= Dell Information Storage and Management V5 course materials

Organizations deploy business continuity solutions to ensure the continuous availability and integrity of business-critical data and applications. Business continuity solutions help meet compliance requirements for data protection, ensuring that data is consistently backed up, secure, and recoverable in case of disasters or system failures. These solutions are essential for maintaining operational resilience and regulatory compliance.

Virtual provisioning is a storage management technique that enables more efficient allocation of storage to compute systems. It allows storage administrators to create virtual storage resources that are presented to compute systems as if they were physical resources, even if the physical storage capacity does not exist. Virtual provisioning supports various types of virtual storage, including thin LUNs and thin clones. Thin LUNs enable shared and rapid expansion with only minor disruptions. Multiple shared storage pools can be created, and each pool can be allocated to multiple thin LUNs. However, virtual provisioning does not prevent issues that arise from oversubscription; it is important to monitor and manage capacity utilization to avoid performance degradation or service disruptions.
