• false

Network Attached Storage device has ______________ components

• NAS head

• storage

• both of the above

• none of the above

NAS head includes the components are___________

• CPU and memory

• network interface cards

• NFS, CIFS, and other protocols for file sharing

• router

NAS provides____________________ to its clients. File I/O is a high-level request that specifies the file to be accessed

• second-level data access

• third-level data access

• four-level data access

The process of handling I/Os in a NAS environment is as ____________________

• The requestor (client) packages an I/O request into TCP/IP and forwards it through the network stack

• The NAS device converts the I/O request into an appropriate physical storage request

• When the NAS device receives data from the storage, it processes and repackages the data into an appropriate file protocol response

• The NAS device packages this response into TCP/IP again and forwards it to the client through the network

• Its operating system is optimized for file I/O which performs better than a general-purpose server

NAS devices does not support multiple file-service protocols to handle file I/O requests

• true

• false
