NEW QUESTION # 19
An architect is helping an organization with the Physical Design of an NSX-T Data Center solution. This information was gathered during a workshop about ESXi Host networking:
A total of 50 ESXi hosts to be configured as Transport Nodes.
All ESXi hosts have a dedicated 2 X Intel 10Gbps Physical Network adapter for the Overlay Traffic.
To achieve low latency, high throughput, redundancy, and performance, which two NIC teaming policies should the architect recommend? (Choose two.)
- A. Load Balance Source
- B. Failover Order
- C. Load Balance Port ID
- D. Load Balance Source MAC
- E. Load Balance Source Port ID
Answer: A,D
Explanation:
Uplink profiles within NSX-T shows that you can only use Load balance Source and Load balance Source MAC, failover order doesnt provide any load balancing or high throughput https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/installation/GUID-50FDFDFB-F660-4269-9503-39AE2BBA95B4.html
https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/installation/GUID-50FDFDFB-F660-4269-9503-39AE2BBA95B4.html Failover Order: Select an active uplink is specified along with an optional list of standby uplinks. If the active uplink fails, the next uplink in the standby list replaces the active uplink. No actual load balancing is performed with this option. Load Balance Source: Select a list of active uplinks. When you configure a transport node, you can pin each interface of the transport node to one active uplink. This configuration allows use of several active uplinks at the same time. Load Balance Source MAC Address: Select an uplink based on a hash of the source Ethernet.

- NSX Manager must be set up to use FQDN.
Data Plane Recovery
- The same internet provider must be used if public IP addresses are exposed through services such as NAT or load balancer.
- The HA mode for the tier-0 gateway must be active-standby, and the failover mode must be preemptive.
Cloud Management System
- The cloud management system (CMS) must support an NSX-T Data Center plug-in. In this release, VMware Integrated OpenStack (VIO) and vRealize Automation (vRA) satisfy this requirement.

NEW QUESTION # 29
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. Modify the Spanning Tree Protocol to increase the time to transition to the forwarding state.
- E. Configure switch ports with a Dynamic Trunking Protocol.
Answer: B,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).
