A network administrator has been tasked with deploying a 3-tier application across two data centers. Tier-1 and tier-2 will be located in Datacenter-A and tier-3 will be located in Datacenter-B.
Which NSX components are needed to make this deployment functional?
A. A universal transport zone deployed with a universal distributed logical router (UDLR), a universal logical switch and two local logical switches connected to the UDLR.
B. A universal transport zone deployed with a universal distributed logical router (UDLR), two universal logical switches and a single logical switch connected to the UDLR.
C. A universal transport zone deployed with a universal distributed logical router (UDLR) and three universal logical switches connected to the UDLR.
D. A universal transport zone, a universal distributed logical router (UDLR) and three local switches in each data center connected to the UDLR
Correct Answer: C — because there is no ESG in answers. (Describeed by Aria)
You must use a universal logical router to route between universal logical switches. If you need to route between a universal logical switch and a logical switch, you must use an Edge Services Gateway
