NEW QUESTION # 46
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. Configure redundant physical switches to enhance availability.
- B. Configure switch ports with a Dynamic Trunking Protocol.
- C. Configure switch ports that connect to ESXi host manually as trunk ports.
- D. Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.
- E. Use only IPv4 addressing in all deployments.
Answer: A,C
Explanation:
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).
