Which two VMware recommendations should an architect follow when configuring top of rack (ToR) switches in an NSX-T Data Center environment? (Choose two.)
A.
Use only IPv4 addressing in all deployments.
B.
Configure redundant physical switches to enhance availability.
C.
Configure switch ports that connect to ESXi host manually as trunk ports.
D.
Configure switch ports with a Dynamic Trunking Protocol.
E.
Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.
BC is Correct:
Top of Rack Physical Switches
When configuring top of rack (ToR) switches, consider the following best practices:
- Configure redundant physical switches to enhance availability.
- Configure switch ports that connect to ESXi hosts manually as trunk ports. Virtual switches
are passive devices and do not support trunking protocols, such as Dynamic Trunking
Protocol (DTP).
- Modify the Spanning Tree Protocol (STP) on any port that is connected to an ESXi NIC to
reduce the time to transition ports over to the forwarding state, for example using the Trunk
PortFast feature found in a Cisco physical switch.
- Provide DHCP or DHCP Helper capabilities on all VLANs used by TEP VMkernel ports. This
setup simplifies the configuration by using DHCP to assign IP address based on the IP subnet
in use.
- Configure jumbo frames on all switch ports, inter-switch link (ISL), and switched virtual
interfaces (SVIs).

B and C are correct. E would be correct if it was reduce instead of increase the time:

Also B should be correct...but is noit strictly related with configuration but it is an architectural decision to improve avalaibility so basically agree with C,D
The correct answers are BC
