質問 # 29
When deploying east-west network introspection, which Service Virtual Machine (SVM) deployment method achieves the least amount of traffic hair pinning?
- A. Place a partner SVM on each compute cluster node.
- B. Centralize partner SVMs in a service cluster.
- C. Create a secondary vNIC on each quest VM for SVM communication.
- D. Add partner SVMs to an edge cluster.
"For SVMs deployed on compute hosts, an SVM does not need to be installed on every host. Some customers prefer to deploy the partner SVM on each host to achieve the least amount of traffic hairpinning. When the partner SVM is deployed in a service cluster, traffic is sent from the compute hosts across the overlay to the hosts in the service cluster."
正解：A

"If you move an alarm into a Suppressed state, you are prompted to specify the duration in hours. After the specified duration passes, the alarm state reverts to Open. However, if the system determines the condition has been corrected, the alarm state changes to Resolved." https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-EB1BB1D3-8892-4890-BE74-EF43CFC75F19.html

* A maximum of eight ECMP paths are supported.
* Hashing is based on 2-tuple IP source and destination addresses.
