CompTIA A+ Core 1 (220-1001) — Question 394

A thin client in a VDI environment receives the OS by connecting to the network through a number of devices. Which of the following is FIRST in the chain?

Answer options

• A. NIC
• B. Router
• C. VLAN
• D. Switch

Correct answer: A

Explanation

The Network Interface Card (NIC) is essential as it is the first point of connection for the thin client to access the network. Without the NIC, the thin client cannot communicate with any other devices like routers or switches. The other options are subsequent in the data transmission chain and rely on the NIC to establish the initial connection.
