What are two advantages for using NSX for vSphere’s Logical Switching? (Choose two.)
A.
Expands the number of available VLANs.
B.
Allows for Layer 2 switching over Layer 3 infrastructure.
C.
Distributes Layer 3 data across multiple hypervisors.
D.
Provides for 10,000 logical segments.
I would say B definitely and D strongly. A is not true. C does not require NSX at all.
Not sure what the maximum is for logical segments.

D. is not possible. VXLAN expands the number of available logical Ethernet segments from 4094 to over 16 million logical segments, so a. is correct

A is not correct. You cannot expand the number of VLANs.

A has to be correct as VXLAN would overlay existing transport VLAN and enable to create 16Mil (possibly) network segements.

VXLAN is not VLAN.
VLAN is at Layer2 level.
VXLAN is at Layer 3. Encapsulating L2 over L3. VLAN technology is not aware of the VXLAN and then, the number of VLANs is not extended.

D is good. It doesn’t say a “maximum” of 10,000 segments, it says it provides for 10k. Which is more than standard VLANs can offer.

Are these questions still valid?

It should be A & B.
VXLAN is an extention of VLAN, so it allows extention beyound the current 4096 VLAN limits.
D should not be correct, its 10,000 vswitches supported, not logical segments.

I read wrong, the answer should be B & D

If anyone is trying for the 2V0-642 (aka NSX 6.2 exams), almost none of the 170+ questions appears in the exams.
I managed to pass with 330 (300 to pass). I did all the tests here, read up some documentations and played with NSX in my firm. So just doing the tests here will not help you pass the exams as almost none of the questions appear for 2V0-642 exams.
There is a lot of focus on the following:
– cross vcenter requirements, setup and operations, with uDLR, uTZ, HA, etc
– network topology/protocols and how they work with NSX example, OSPF, BGP, etc
– security groups and data security
– DFW and FW in Edges
– troubleshooting tools like netflow IPfix, etc
– good understanding of vSphere VDS and VSS and ESXi
– VXLAN flows with NSX

Had the same issue Kelvin. Unfortunately for me, I got a 290 something. Do you know of a good study guide for the 2V0-642? I have been looking for one and have not had much luck.
Thanks,
Josh

Even I had rough times I scored 274… I am preparing hard way so I can clear it.
