QUESTION 26
An NSX Edge Service Gateway has two interfaces:
Internal interface named Internal Access
— IP address = 10.10.10.1
— Network mask = 255.255.255.0
Uplink interface named Physical Uplink
— IP address = 20.20.20.1
— Network mask = 255.255.255.0

Which three steps should the vSphere administrator do to add the SNAT rule? (Choose three)
A. Apply the SNAT rule to the Internal Access interface.
B. Select 10.10.10.1 as the translated source IP.
C. Apply the SNAT rule on the Physical Uplink interface.
D. Select 10.10.10.0/24 as the original subnet.
E. Choose 20.20.20.2 as the translated source IP.
Answer: CDE
QUESTION 27
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?
A. Create a DNAT rule with the original port of 69 and translated port of 1069.
B. Create a SNAT rule with the original port of 1069 and translated port of 69.
C. Create a SNAT rule with the original port of 69 and translated port of 1069.
D. Create a DNAT rule with the original port of 1069 and translated port of 69.
Answer: A
QUESTION 28
Which two actions take place when an active NSX Edge instance fails? (Choose two.)
A. Once the original NSX Edge instance is recovered, it preempts the other NSX Edge instance and takes over the active role.
B. The standby NSX Edge instance becomes the active instance and requests routing updates from the routing neighbors.
C. Once the original NSX Edge instance is recovered, the NSX Manager attempts to place it on a different host from the other NSX Edge instance.
D. The standby NSX Edge instance becomes the active instance and retains any routing neighbor adjacencies.
Answer: CD
QUESTION 29
