Question #1
Which two of the following will be used for Ingress traffic on the Edge node supporting a Single Tier topology? (Choose two.)
Select 2 answers.
Correct answer: B, C
Explanation
The two interfaces that will be used for ingress traffic on the Edge node supporting a Single Tier topology are: B. Tier-0 Uplink interface C. Downlink Interface for the Tier-0 DR The Tier-0 Uplink interface is the interface that connects the Tier-0 gateway to the external network. It is used to receive traffic from the physical router or switch that is the next hop for the Tier-0 gateway. The Tier-0 Uplink interface can be configured with a static IP address or use BGP to exchange routes with the external network. The Downlink Interface for the Tier-0 DR is the interface that connects the Tier-0 gateway to the workload segments. It is used to receive traffic from the VMs or containers that are attached to the segments. The Downlink Interface for the Tier-0 DR is a logical interface (LIF) that is distributed across all transport nodes that host the segments. The Downlink Interface for the Tier-0 DR has an IP address that acts as the default gateway for the VMs or containers on the segments.
Question #7
When a stateful service is enabled for the first lime on a Tier-0 Gateway, what happens on the NSX Edge node'
Correct answer: A
Explanation
The answer is A. SR is instantiated and automatically connected with DR. SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1 The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1 When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2 According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3 To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources: VMware NSX Documentation: NSX Edge Components 1 VMware NSX 4.x Professional: NSX Edge Architecture VMware NSX 4.x Professional: NSX Edge Routing
