Exam D-PE-FN-01 Topic 5 Question 28 Discussion

Network Attached Storage (NAS) is commonly utilized in backup solutions because it provides a centralized, scalable storage option that can be accessed over a network, making it ideal for storing and archiving large volumes of backed-up data. NAS devices support file-level access protocols like NFS and SMB, which are suitable for backup applications, allowing multiple servers or clients to store data efficiently. Unlike SAN arrays, which are more geared toward block-level storage for high-performance applications, NAS is cost- effective for backup and archiving needs. SSDs and NVMe drives are faster but more expensive for large- scale archiving, while hard disks are basic components but lack the networked accessibility of NAS. RAM and CPU cache are volatile and not suitable for persistent storage. This choice aligns with backup infrastructure design principles, emphasizing reliability and accessibility for on-site and off-site data protection. In contrast, options like SAN are better for enterprise storage but not primarily for backups due to higher complexity and cost.
