2V0-41.23 Exam Dumps : VMware NSX 4.x Professional

Distributed Firewall on VDS is a feature of NSX-T Data Center that allows users to install Distributed Security for vSphere Distributed Switch (VDS) without the need to deploy an NSX Virtual Distributed Switch (N-VDS). This feature provides NSX security capabilities such as Distributed Firewall (DFW), Distributed IDS/IPS, Identity Firewall, L7 App ID, FQDN Filtering, NSX Intelligence, and NSX Malware Prevention. To enable this feature, the following requirements must be met in the environment:

• The NSX version must be 3.2 and later1. This is the minimum version that supports Distributed Security for VDS.
• The VDS version must be 6.6.0 and later1. This is the minimum version that supports the NSX host preparation operation that activates the DFW with the default rule set to allow.

According to the VMware NSX Documentation, these are the two places where you need to configure the VLANs used in VRF Lite:

• Uplink trunk segment: This is a segment that connects a tier-0 gateway to a physical network using multiple VLAN tags. You need to configure the VLAN IDs for each VRF on this segment.
• Uplink interface of the VRF gateway: This is an interface that connects a VRF gateway to an uplink trunk segment using a specific VLAN tag. You need to configure the VLAN ID for each VRF on this interface.

Route-based VPN is a VPN type that uses Virtual Tunnel interfaces (VTI) to establish IPSec tunnels between an NSX Edge node and remote sites2. A VTI is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The VTI acts as an end point of the IPSec tunnel and routes traffic between the NSX Edge node and the remote site2. Route & SSL based VPNs, Policy & Route based VPNs, and SSL-based VPN are not VPN types that use VTI. References: Virtual Private Network (VPN)
