Answer:
Trunk
Explanation:
Gigabit switches are meant for expanding the ethernet. Through this, you can add more PC to the ethernet. A managed switch is meant for providing more tailored features and tools to the users. The unmanaged switch only allows the two devices on the network to communicate with each other, as it just provides the connectivity. And for setting up the VLANs on it, we need the Trunk Switch. And hence, the correct option is Trunk.
