A customer needs an OpenStack-based cloud datacenter with several virtual machines that will be placed in
multiple VLANs. The customer needs to use Virtual Extensible LAN (VXLAN)
Or Generic Routing Encapsulation (GRE) technology to support multi-tenant traffic. The architect recommends
the following HPE server equipment:
BladeSystem c7000 enclosure
Virtual Connect 20/40 F8 modules
BL460c Gen9 servers with FlexFabric 20Gb 2-port 650FLB Adapters
Which rationale supports the architect’s recommended configuration?
A.
It allows RDMA over Converged Ethernet (RoCE)
B.
It improves performance of OpenStack instance provisioning
C.
It improves performance of overlay networks with a tunnel offload engine
D.
It allows configuration of interconnect module stacking
Explanation:
FlexFabric 20/40 F8 do not support RoCE so A is incorrect.
One feature of FlexFabric 650FLB is “Improve performance of overlay networking with tunnel offload on a 20 GbE adapter (VXLAN and NVGRE)”.
So we can exclude A for sure, B is not mentioned at all on Study Guide.
I would go for C.
