- B. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
- C. Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration
- D. Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA
Answer : A
Question 7

Which vSphere feature should the vSAN administrator implement?
- A. vSphere Distributed Services Engine
- B. vSphere High Availability
- C. vSphere Fault Tolerance
- D. vSphere Distributed Resource Scheduler
Answer : C
Question 8
What is the purpose of host rebuild reserve in vSAN?

- B. Reserves space in case of single host failure
- C. Stores vSphere HA heartbeats
- D. Allocates capacity for vCLS
Answer : B
Question 9
An architect is designing a vSAN stretched cluster and needs to ensure that data remains on a given site in case of a network partition between the sites.
Which configuration would do this?
- A. Preferred and secondary sites
- B. vCenter High Availability
- C. Distributed Resource Scheduler
- D. vSphere High Availability
Answer : A
Question 10
A customer wants to validate if Skyline online health is working for vSAN and finds out that Skyline is not fully configured yet.
What two requirements must be met to make sure that Skyline online health will work? (Choose two.)
- A. Add the Skyline license into Virtual Center
- B. Enable Skyline Health on the vSAN Cluster
- C. Enable CEIP and join the program
- D. Have a working Internet connection
- E. Have vCenter on version 7 or higher
Answer : CD
Question 11
An administrator has been tasked with upgrading existing vSAN OSA cluster hosts with a SSD cache device per host to a NVMe device (hot plug).
Which fact should guide the administrator's action?
- A. The disk group must be deleted on each physical host in the vSAN OSA cluster to use the NVMe device.
- B. The disk group does not need to be removed before adding new cache.
- C. The host must be removed from vSAN OSA cluster before changing cache devices.
- D. The cache disk drives must have a larger capacity.
Answer : A
Question 12
An administrator must choose between deploying a virtual witness or a physical witness for a vSAN Stretched Cluster. The administrator eventually decides to use a virtual witness.
What is a benefit of selecting this approach?
- A. Increased vSAN datastore capacity
