Which two characteristics of the underlying physical network does VMware NSX require for robust IP transport?
A. The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP) and Multichassis Link Aggregation (MLAG).
B. The physical network should provide scalable network I/O using Equal Cost Multipathing (ECMP).
C. QoS is not necessary since classification and marking will be done in the overlay.
D. QoS classification and marking is required to provide end-to-end flow control.
Answer: B,D

- An administrator has deployed NSX in an environment containing a mix of vSphere 5 hosts. The implementation includes the Distributed Firewall Service, but the administrator finds that rules are not being applied to all affected virtual machines. What two conditions would cause this behavior?
- An administrator wishes to control traffic flow between two virtual machines. The virtual machines are in the same subnet, but are located on separate ESXi hosts. The administrator deploys an Edge Firewall to one of the hosts and verifies the default firewall rule is set to deny, but the two virtual machines can still communicate with each other. What task will correct this issue?

- An administrator manages a TFTP server virtual machine that is connected to a Logical Switch with a VNI of 7321. The TFTP server has been configured to use port 1069. An NSX Edge Service Gateway is connected to VNI 7321 and has an uplink interface with access to the physical network. Assume external users can reach the Service Gateway. What should the administrator configure to ensure external connections to the TFTP server are successful?
- Which statement is true regarding an NSX Edge gateway device configured with a DNS Server?
- A vSphere administrator wants to setup an NSX Edge Service Gateway to provide traveling employees secure access to company servers located in specific network segments within the corporate Data Centers. The solution has to be as scalable as possible. Which Virtual Private Network solution will satisfy the administrator's requirements?
- A company has augmented its Data Center infrastructure by using vCloud Hybrid Service during peak hours. The company wants to extend their existing subnets into the cloud while workloads retain their existing IP addresses. The virtual machines in these subnets use an NSX Edge Gateway as their default gateway. Which solution should this company use?
- A vSphere administrator wants to setup an NSX Edge Service Gateway to provide traveling employees secure access to company servers located in specific network segments within the corporate Data Center. The remote access solution must provide a method to authenticate the users. Which two methods can be used with the NSX Edge Service Gateway?
- Which two statements are true regarding Layer 2 VPNs?
- A company hosts an internal website on multiple virtual machines attached to a Logical Switch with VNI 7321. A Distributed Router serves as the virtual machines' default gateway. When an user resolves the URL for the website, the internal DNS server responds with the IP address of one of the virtual machine's IP addresses in a round robin fashion. This approach results in some virtual machines having a much higher number of user sessions than others. The company wants to deploy a NSX Edge Service Load Balancer to improve on this situation. Which distribution method can be configured on the NSX Edge Load Balancer to meet the company's needs?
- A vSphere administrator deployed an NSX Edge Load Balancer in HP mode. What happens in the event the Load Balancer has a failure?
- Which two options are valid distribution methods used by the NSX Edge Load Balancer?
- You are tasked with designing a data center architecture that should maximize the use of vMotion within your environment.
