Which three should be taken into consideration when configuring a Stretched Cluster? (Choose three.)
When configuring a Stretched Cluster, it is crucial to consider the bandwidth between sites, the geographical distance, and the latency between sites. Bandwidth ensures there is sufficient data transfer capability between the sites. Geographical distance is important because as it increases, the complexity of managing latency and bandwidth also increases. Finally, latency between sites must be taken into consideration to ensure efficient operation and data synchronization, because high latency can severely impact performance.
I think A, C, and E are correct. When calculating the bandwidth between the data sites and the witness site the rule of thumb is 2Mbps for every 1000 objects, so knowing the number of objects would be useful. The Geographical distance is irrelevant when the bandwidth and latency are correct.
I think A-D-E are correct
A,C,E bandwith sizing is strictly correlated to objects number
ADE. C is not correct because Stretched Cluster Witness Node size is determined by number of Components not Objects. Version, Latency and Bandwidth are all mentioned: https://core.vmware.com/resource/vsan-stretched-cluster-guide#networking-requirements
A,C,E are correct
C, D, E. VMware design guide explain latency between sites. Stretched cluster was introduced in vSAN version 6.1 and vSAN Stretched Cluster can support a maximum of 45,000 components. https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec6-sub1
