DEA-1TT5 Storage Networking (SAN and NAS)

Question 1

What protocol does NAS primarily use to share files with Windows clients?

Accepted Answer

SMB/CIFS

Answer

NAS systems use SMB (Server Message Block), also known as CIFS, to provide file sharing services to Windows clients on an IP network.

Question 2

What is the maximum speed of a 32Gb Fibre Channel link?

Accepted Answer

32 Gbps with ~3.2 GB/s effective throughput

Answer

A 32Gb Fibre Channel link provides 32 gigabits per second of raw bandwidth, translating to approximately 3.2 GB/s of effective data throughput after encoding overhead.

Question 3

What is a 'fabric' in Fibre Channel networking?

Accepted Answer

The switching infrastructure that interconnects FC devices and provides intelligent routing

Answer

A Fibre Channel fabric is a network of FC switches that enables any-to-any connectivity between initiators (servers) and targets (storage), providing routing, zoning, and name services.

Question 4

What is 'FCoE' (Fibre Channel over Ethernet)?

Accepted Answer

A protocol that encapsulates native Fibre Channel frames within Ethernet frames to converge storage and network traffic on the same links

Answer

FCoE encapsulates Fibre Channel frames inside Ethernet frames, enabling storage and LAN traffic to share the same 10GbE or 25GbE physical infrastructure while preserving FC semantics.

Question 5

In a NAS environment, what is an 'export' or 'share'?

Accepted Answer

A network-accessible directory or file system made available to clients by the NAS server

Answer

An NFS export or SMB share is a defined portion of the NAS file system that is made accessible to specified clients over the network with defined permissions.
