1v0-41.20 Associate VMware Network Virtualization Questions and Answers

To secure two virtual machines attached to the same segment, the customer can configure a distributed firewall rule using NSX Data Center. The NSX Distributed Firewall (DFW) allows for micro-segmentation, providing granular security controls and policies that can be applied to individual virtual machines, even if they are on the same network segment.

VMware HCX Overview

VMware NSX provides network virtualization capabilities within the virtual infrastructure layer of the Software-Defined Data Center (SDDC). NSX abstracts the network infrastructure away from the underlying hardware and provides a software-defined networking layer that allows for the creation, management, and automation of virtual networks.

NSX Intelligence is the solution designed to help detect lateral threat movement on east-west network traffic across multi-cloud environments. It provides real-time visibility, analytics, and security posture monitoring, making it easier to identify and mitigate threats within the network.

The key value for the VMware approach to a software-defined data center (SDDC) is a vendor-agnostic platform. VMware's SDDC architecture supports a wide range of hardware, software, and cloud environments, providing flexibility and interoperability regardless of the underlying vendor.

VMware SDDC Benefits

The NSX-T feature that an administrator should use to secure Virtual Machines on the same Layer Two Segment is the Distributed Firewall. The Distributed Firewall provides micro-segmentation and east-west traffic control directly at the virtual network interface card (vNIC) level, allowing for granular security policies to be enforced within the virtual environment.

To integrate NSX-T Data Center security services while maintaining current security service providers, the following features can help:

A. Guest Introspection: This allows third-party security services to interact with guest virtual machines directly, providing additional security capabilities such as antivirus and antimalware.

C. Network Introspection: This enables the integration of third-party network security services, such as IDS/IPS, to monitor and protect network traffic within the NSX environment.

The Data Plane in the NSX-T Data Center architecture performs the network traffic forwarding. The Data Plane is responsible for the actual handling of packets, including switching, routing, and firewall enforcement. It operates based on the instructions from the Control Plane.

NSX Cloud is the VMware product designed to manage and extend data center networks into VMware Cloud on AWS and Microsoft Azure Cloud. NSX Cloud provides consistent networking and security for applications running in both private data centers and public clouds, ensuring seamless connectivity and uniform policy enforcement across hybrid environments.

The Management Plane in the NSX-T Data Center Architecture is responsible for create, read, update, and delete (CRUD) operations. This plane includes the NSX Manager and provides a single point for configuration and management of the NSX environment.

The three types of transport nodes in NSX-T are:

A. NSX Edges: These are nodes that provide edge services and north-south routing.

D. Bare-metal servers: These servers can be configured as transport nodes to extend NSX-T networking and security to physical workloads.

F. Hypervisors: These nodes run virtualized workloads and host NSX-T virtual switches, enabling NSX-T to manage network traffic within the virtual environment.

vCenter Server is required to deploy NSX Edge virtual machines. The NSX Edge provides routing, firewall, VPN, load balancing, and other network services. The deployment and management of NSX Edge virtual machines are handled through the vSphere Web Client, which necessitates the use of vCenter Server.
