質問 # 34
An architect is helping an organization with the Logical Design of an NSX-T Data Center solution.
This information was gathered during the Assessment Phase:
There is a performance based SLA for East - West traffic.
The business critical applications require prioritization of their traffic.
One of the services is a file share and has a high demand for bandwidth.
Which selection should the architect include in their design? (Choose the best answer.)

A. Include a segment QoS profile and review the impact of utilizing this feature.
B. Monitor East-West traffic throughout normal business cycles.
C. Meet with the organization's application team to get additional information.
D. Review average North/South traffic from the core switches and firewall.

正解：A

解説：
QoS provides high-quality and dedicated network performance for preferred traffic that requires high bandwidth. The QoS mechanism does this by prioritizing sufficient bandwidth, controlling latency and jitter, and reducing data loss for preferred packets even when there is a network congestion.

質問 # 37
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.

A. Load Balance Source Port ID
B. Load Balance Source
C. Load Balance Source MAC
D. Load Balance Port ID
E. Failover Order

正解：B、C

解説：
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.
