350-601 Question #636: Real Exam Question with Answer & Explanation

Question

What is a disadvantage of deploying network-attached storage (NAS) versus Fibre Channel for storage?

Options

• ANAS is more complex and expensive to implement.
• BNAS lacks the scalability and performance of Fibre Channel.
• CNAS centralizes storage devices, which makes them easier to manage.
• DNAS operates independently of an organization's operating system.

Explanation

Network-Attached Storage (NAS) and Fibre Channel (FC) are two different storage architectures, each with advantages and disadvantages. Disadvantage of NAS Compared to Fibre Channel: Lower Performance and Scalability: - NAS relies on TCP/IP over Ethernet, which introduces higher latency and lower throughput compared to Fibre Channel, which is optimized for high-speed, low-latency - NAS may experience bottlenecks due to network congestion and shared bandwidth, making it less ideal for high-performance applications. - Fibre Channel, on the other hand, operates on a dedicated storage network, providing higher speeds, lower latency, and better scalability.
