3V0-42.20 Exam - Question 34


Which two VMware recommendations should an architect follow when configuring top of rack (ToR) switches in an NSX-T Data Center environment? (Choose two.)

Show Answer
Correct Answer: BC

When configuring top of rack (ToR) switches in an NSX-T Data Center environment, it is important to follow certain best practices to ensure optimal performance and reliability. Configuring redundant physical switches enhances availability by providing failover capabilities in case one switch fails. Additionally, switch ports that connect to ESXi hosts should be manually configured as trunk ports because virtual switches are passive devices and do not support trunking protocols like Dynamic Trunking Protocol (DTP). These measures help ensure a stable and robust network setup for an NSX-T Data Center environment.

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). https://docs.vmware.com/en/VMware-Validated-Design/5.0.1/vmware-validated-design-501-sddc-nsxt-workload-architecture-design.pdf

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

B and C are correct. E would be correct if it was reduce instead of increase the time: https://docs.vmware.com/en/VMware-Validated-Design/5.0.1/vmware-validated-design-501-sddc-nsxt-workload-architecture-design.pdf
