Question

A network engineer is tasked with segmenting the company network to improve security protections. Which of the following strategies will the engineer most likely utilize to segment devices attached to the same switch?

Answer 1

To segment devices attached to the same switch while improving security protections, the network engineer will most likely utilize **VLANs (Virtual Local Area Networks)**.

VLANs allow network administrators to create distinct broadcast domains within a single physical switch. By segmenting the network into different VLANs, the engineer can isolate traffic between devices on the same switch, thus enhancing security by limiting unwanted access and reducing the potential impact of broadcast traffic.

For example:
- Devices belonging to the finance department could be placed in one VLAN, while those in the HR department could be placed in another VLAN. This ensures that the two groups do not have direct access to each other's traffic, providing an additional layer of security.

Furthermore, VLANs can be used in conjunction with access control lists (ACLs) and other security measures to reinforce the segmentation and protect sensitive data.

In summary, VLANs are the most likely strategy to be utilized for segmenting devices on the same switch to improve security protections.
