Cloud tiering is a technology that automatically moves inactive or infrequently accessed data from high-performance primary storage to lower-cost secondary storage, such as cloud-based object storage. This process is based on policies that are defined by the IT administrator. Cloud tiering is a part of the secondary storage tier, which is typically used for storing inactive or infrequently accessed data that does not require the high performance or low latency of primary storage. The primary storage tier is used for storing active or frequently accessed data that requires high performance and low latency. The application tier is used for hosting applications and services, while the policy tier is used for defining and enforcing data management policies. Reference: Section 4.4 Secondary Storage Tier, page 239.

RAID 6 is characterized by double parity, which means that it uses two parity blocks to protect against data loss. This double parity allows RAID 6 to tolerate the failure of two drives within the RAID array, making it more reliable than RAID 5, which only uses single parity.

Dell Certification Overview

The Business Continuity layer in a modern data center architecture is responsible for defining strategies and measures to minimize the impact of both planned and unplanned outages. This layer ensures that the organization can continue its critical operations without significant downtime. It includes disaster recovery planning, data protection, backup, and restore processes, ensuring the availability and resilience of IT services during disruptions.

Unified storage systems allow for the management of both file and block data in a single system, leading to better storage utilization. By consolidating different types of data, storage resources can be more efficiently allocated, reducing the amount of stranded or unused capacity and optimizing overall storage utilization.

In Fibre Channel networks, an E_port (Expansion port) is used to connect two FC switches. The "X" in the exhibit indicates a connection between two FC switches, representing an E_port, which allows the creation of larger fabrics by linking multiple switches.

References: Dell EMC ISM V5 Module 4, "Fibre Channel SAN," details the different types of FC ports and their functions.

A file server is a computer that provides a location for shared disk access, i.e. storage of computer files (such as text, image, sound, video) that can be accessed by other computers on the same network2. A general purpose file server is a file server that serves shares such as team shares, user home folders, work folders and software development shares3.

According to 4, a purpose-built NAS solution is a storage system that simplifies data management with easy NAS file sharing. A NAS solution provides shared access to files over a network using protocols such as NFS and SMB/CIFS5.

Based on these definitions4, a benefit of using a purpose-built NAS solution vs general purpose file servers is A. provides more efficient file sharing across Windows and Linux users6. This is because a purpose-built NAS solution supports both NFS and SMB/CIFS protocols that enable file sharing across different operating systems5.

The Cisco MDS-9132T switch model supports NVMe over Fibre Channel (FC) in a 32Gb/s SAN fabric. NVMe (Non-Volatile Memory Express) is a protocol designed for SSDs to exploit the performance potential of flash technology and provides faster data access compared to traditional SCSI protocols. The MDS-9132T is optimized for modern data centers requiring high-performance storage connectivity.

Data Center Bridging (DCB) is a set of IEEE standards that provide a lossless Ethernet network for Fibre Channel over Ethernet (FCoE). DCB enhances Ethernet networks to support the lossless delivery of storage traffic and other high-priority data by incorporating features like Priority-based Flow Control (PFC) and Enhanced Transmission Selection (ETS). These features ensure that storage traffic, such as FCoE, can be transmitted reliably over Ethernet without packet loss.References:= Dell Information Storage and Management V5 course materials

The Fibre Channel (FC) protocol stack is divided into several layers, each responsible for different functions:

FC-4: Mapping interface – This layer maps upper layer protocols to the lower FC layers.

FC-2: Routing and flow control – This layer handles the routing and flow control of data frames.

FC-1: Encode and decode – This layer is responsible for the encoding and decoding of data to ensure proper transmission over the network.

FC-0: Physical – This layer handles the physical transmission of data, including the cables, connectors, and signaling.

Therefore, the correct alignment of functions with each layer of the FC Protocol Stack is: C. Mapping interface Routing and flow control Encode and decode Physical

Dell Certification Overview

Serial Attached SCSI (SAS) is a protocol that offers a cost-effective balance between I/O performance and storage capacity, making it ideal for midrange storage applications. SAS devices provide higher data transfer rates and improved scalability compared to SATA while being more affordable than NVMe solutions, which are typically used for high-performance environments.
