NEW QUESTION # 14
A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.
The following requirements must be met:
* Each MSSQL cluster is made up of 3 nodes
* Highest possible availability against node failures
* Some of the vSAN clusters will only consume storage
What should the architect recommend?

- D. vSAN Direct
Answer: A
Explanation:
Reference:
vSAN 6.7 expands the functionality of the vSAN iSCSI Target service to provide the SCSI-3 persistent reservations support for shared disks for windows failover cluster if using the SQL Server FCI, high availability mode is a requirement. The vSAN iSCSI Target service at the vSAN cluster level should be enabled for this purpose. VSAN streched cluster may be used to increase the data availability across data centres. https://blogs.vmware.com/virtualblocks/2019/03/26/considerations-for-running-microsoft-sql-server-workloads-on-vmware-vsan/

NEW QUESTION # 24
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?
- A. vSAN proactive tests haven't been run yet.
- B. vSAN network diagnostic mode is not enabled.
- C. vSAN performance verbose mode is not enabled.
- D. vSAN performance service is turned off.
Answer: D
Explanation:
Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.
