Refer to the exhibit. An administrator would like to change the private IP address of the NAT VM I72.l6.101.il to a public address of 80.80.80.1 as the packets leave the NAT-Segment network. Which type of NAT solution should be implemented to achieve this?
Correct Answer: B
SNAT stands for Source Network Address Translation. It is a type of NAT that translates the source IP address of outgoing packets from a private address to a public address. SNAT is used to allow hosts in a private network to access the internet or other public networks1 In the exhibit, the administrator wants to change the private IP address of the NAT VM 172.16.101.11 to a public address of 80.80.80.1 as the packets leave the NAT-Segment network. This is an example of SNAT, as the source IP address is modified before the packets are sent to an external network. According to the VMware NSX 4.x Professional Exam Guide, SNAT is one of the topics covered in the exam objectives2 To learn more about SNAT and how to configure it in VMware NSX, you can refer to the following resources: VMware NSX Documentation: NAT 3 VMware NSX 4.x Professional: NAT Configuration 4 VMware NSX 4.x Professional: NAT Troubleshooting 5
Question 3
Which table on an ESXi host is used to determine the location of a particular workload for a frame-forwarding decision?
What needs to be configured on a Tler-0 Gateway lo make NSX Edge Services available to a VM on a VLAN-backed logical switch?
Correct Answer: B
Explanation To make NSX Edge Services available to a VM on a VLAN-backed logical switch, you need to configure a VLAN Uplink on the Tier-0 Gateway. A VLAN Uplink is a logical interface that connects the Tier-0 Gateway to the physical network and provides external connectivity for the NSX Edge Services1. A VLAN Uplink can be configured on the NSX Manager UI by selecting Networking > Tier-0 Gateways > Interfaces > Set > Add Interface1. https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-D641380B-4C8E-4C8A-AF64-4261A266
Question 5
In an NSX environment, an administrator is observing low throughput and congestion between the Tier-O Gateway and the upstream physical routers. Which two actions could address low throughput and congestion? (Choose two.)
Correct Answer: B,C
Explanation ECMP (Equal Cost Multi-Path) is a routing protocol that increases the north and south communication bandwidth by adding an uplink to the tier-0 logical router and configure it for each Edge node in an NSX Edge cluster2. The ECMP routing paths are used to load balance traffic and provide fault tolerance for failed paths2. The tier-0 logical router must be in active-active mode for ECMP to be available2. A maximum of eight ECMP paths are supported2. Configuring ECMP on the tier-0 gateway can address low throughput and congestion by distributing the traffic among multiple paths and avoiding bottlenecks. Deploying Large size Edge node/s can also address low throughput and congestion by providing more resources (memory, CPU, disk) for the Edge node to handle the network traffic. The NSX Edge VM system requirements vary depending on the appliance size, which affects the bandwidth, NAT/firewall, load balancer, and VPN capabilities of the Edge node1. A Large size Edge node has 32 GB memory, 8 vCPU, 200 GB disk space, and can support 2-10 Gbps bandwidth, L2-L4 features, and L7 load balancer1. An Extra Large size Edge node has 64 GB memory, 16 vCPU, 200 GB disk space, and can support more than 10 Gbps bandwidth, L2-L4 features, L7 load balancer, and VPN1. Deploying a larger size Edge node can improve the performance and capacity of the tier-0 gateway.
