A small business wants to segment its network to isolate guest Wi-Fi from the internal network. They have a single wireless access point and a single switch. Which type of segmentation is most appropriate and cost-effective?

Virtual segmentation using a hypervisor

Logical segmentation using VLANs

Physical segmentation by installing a second access point and switch

Subnet segmentation without VLANs

Why is it important to document and review network segmentation rules regularly?

To reduce the need for IP addressing

To ensure the network remains aligned with current security requirements and to remove outdated rules

To increase the number of VLANs on the network

To ensure that all segments have the same security policy

In a segmented network, where is a firewall typically placed?

At the boundary between segments to control traffic flow

Only at the internet connection point

A security architect is implementing microsegmentation in a virtualized data center. They want to enforce a policy that only allows the application server to communicate with the database server on TCP port 1433, and only from the application server's IP address. Which technology is best suited for this?

A traditional perimeter firewall

A distributed firewall integrated with the hypervisor

Which type of device is commonly placed in a DMZ?

Database servers containing sensitive internal data
