The correct answer is A & E. As per VMware documentation: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-5D7E3D43-6497-4273-99C1-77613C36AD75.html Requirements for Multisite Deployments The bandwidth must be at least 1 Gbps and the latency (RTT) must be less than 150 ms. MTU must be at least 1600. 9000 is recommended.

A and E. Fragmentation on RTeps is allowed, so "must use 1600" is wrong. It would need to be 1700 anyway as a minimum. 9000 recommended is true.

A & E are correct. Requirements for Multisite Deployments Inter-site Communication - The bandwidth must be at least 1 Gbps and the latency (RTT) must be less than 150 ms. - MTU must be at least 1600. 9000 is recommended. NSX Manager Configuration - Automatic backup when NSX-T Data Center configuration changes must be enabled. - 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. https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/administration/GUID-5D7E3D43-6497-4273-99C1-77613C36AD75.html

AE are correct. Read the question. It says 'VMware recommendation' not 'at least'. The recommendation is 9000. So, AE
