What does NAS stand for in the context of computer networks?

• Network Access Server

• Network Attached Storage

• Network Application Service

• Network Array System

Which of the following best describes the primary function of a NAS device?

• To store and share files over a network

• To manage network traffic

• To host websites

Which component is NOT typically part of a NAS system?

• Hard drives

• Network interface card

• Graphics processing unit (GPU)

• It cannot be expanded

Which of the following is a disadvantage of NAS?

• It can be accessed by multiple users

• It may become a bottleneck if network bandwidth is limited

• It supports data redundancy

• It is always more secure than direct-attached storage

Which of the following is NOT a typical maintenance task for NAS devices?

• Replacing failed hard drives

• Updating firmware

• Cleaning the device physically

• Replacing the network switch every month

What is the main purpose of RAID in NAS systems?

• To increase network speed
