CompTIA Network+ (N10-007) — Question 603

A developer has asked a network engineer for a small network segment of five computers connected via a Layer 1 device, configured in a star topology, and segregated from the corporate network. Which of the following would BEST fulfill the developer's request?

Answer options

• A. Connect the five PCs to a hub that is not connected to the corporate network.
• B. Connect the five PCs to a switching router and assign the PCs to a separate VLAN.
• C. Connect the five PCs to a hardware firewall that is connected to the router.
• D. Connect the five PCs to a switch and configure the ports with implicit deny ACLs for outbound traffic.

Correct answer: A

Explanation

The correct answer is A because connecting the five PCs to a hub that is not connected to the corporate network creates a simple and isolated network segment as requested. Options B and D introduce unnecessary complexity with VLANs and ACLs, while option C does not provide the required isolation since a firewall would still allow some level of connection to the corporate network.
