Nutanix Certified Associate Practice Exam

How can an administrator ensure limited traffic between web, application, and database VMs in a Nutanix environment?

1. Separate the web, application, and database VMs onto dedicated VLANs.

2. Create a network for each type of VM and use policy-based routing.

3. Categorize the VMs in Prism Central and utilize Flow to set a security policy.

4. Configure a security policy and service chain redirecting the server traffic through the firewall.

The correct answer is: Categorize the VMs in Prism Central and utilize Flow to set a security policy.

To ensure limited traffic between web, application, and database VMs in a Nutanix environment, utilizing Flow in Prism Central to set a security policy is an effective approach. Flow is Nutanix's network security feature that provides visibility and control over traffic between virtual machines. By categorizing the VMs in Prism Central, an administrator can leverage Flow to define and enforce security policies that dictate how and if different types of VMs can communicate with each other. This method allows for granular control over traffic between the VMs, enabling the administrator to establish rules that limit or allow communication based on specific criteria, such as VM type or role. This helps to prevent unauthorized access and potential security risks, creating a more secure environment while still facilitating necessary communication under controlled conditions. Implementing this strategy enhances the overall security posture of the Nutanix environment, as it offers both visibility into traffic patterns and the ability to enforce restrictions as needed. In contrast, the other options, while they may provide other forms of network isolation or routing, do not leverage the specific security and visibility capabilities that Flow offers, making it a standout solution in this scenario.
