Which NSX component decreases layer 2 broadcast domains and improves network efficiency and scale?
Which NSX component decreases layer 2 broadcast domains and improves network efficiency
and scale?
B
The Answer is A – the use of Logical Switches – which means the implementation of VXLAN segments, means smaller layer 2 physical domains and more layer 3 aggregated bandwidth between layer 2 segments, providing a more scalable network.
Michael,
The answer is indeed B. As stated by VMware NSX documentation, “Dynamic routing provides the necessary forwarding information between layer 2 broadcast domains, thereby allowing you to decrease layer 2 broadcast domains and improve network efficiency and scale.”

Support michael. Answer should be A. Layer 2 not require router and logical router is different than logical routing
Ask this question for physical hardware: Which network component decreases layer 2 broadcast domains and improves network efficiency and scale?
A VLAN
B Router
C Firewall
D VPN
I answer A: VLAN. A router connects VLAN with layer 3. If you have a big broadcast domain you split your network up into VLAN’s. Now we translate this to NSX and I come to answer A. But if you read the text VMware puts on: https://pubs.vmware.com/NSX-6/index.jsp#com.vmware.nsx.admin.doc/GUID-885CE12B-43BF-4259-9DE5-9A7CD9EA5104.html The answer is B:
This is bad info of VMware, never decrease broadcast with more routers 🙂
Agree, but… If you segment brodcast domain with VLANs – you need a Router to implement the same level of comunication as before segmentation… B from my point of view.
I want to bring light into this discussion. Logical Switches cannot decrease any broadcast domain, that’s just done by the use of different subnets and thereby the use of routers are necessary. Of course you can use VLANs, which is logical segmentation at all – but then you need routers (for example “on a stick”) to route traffic between these different subnets.
If they talk about scalability, they mean Microsegmentation, I think.
The interesting problem is WHAT L2 broadcast domains, on the physical network vxlan and logical switches reduce the size of L2 domains (can do L3 access switches). So if you are talking about underlay logical switches, overlay logical routers
