An architect is designing the datastore configuration of a new vSphere-based solution. The following information was obtained during the initial meeting with the customer: There is currently 500 production and DMZ virtual machine workloads spread evenly across the primary and secondary site. The profile of the workloads (per site) is as follows: - DMZ: -- 75 x Small: 1 vCPU, 2GB RAM, 200 GB disk - Production: -- 50 x Small: 1 vCPU, 2 GB RAM, 200 GB disk -- 100 x Medium: 2 vCPU, 4 GB RAM, 200 GB disk -- 25 x Large: 4 vCPU, 8 GB RAM, 500 GB disk The average IO Profile per workload is 70/30 read/write. The solution should cater to 10% storage growth in the first year. The solution should cater to 15% virtual machine snapshot overhead. The storage team has confirmed: - A scalable external storage array has been deployed per site to support the storage requirements. - The storage array will connect to all hosts using a dedicated Fibre Channel storage area network fabric. - Usable storage capacity is available in 10 TB LUNs. - As many LUNs as required can be provided. - Every effort should be made to ensure the number of required LUNs is minimized. The security team has stated that all DMZ and production workloads must remain logically isolated from each other. Given the information provided, which three design decisions should the architect make to meet the requirements? (Choose three.)
Answer options
A: Six 10TB VMFS datastores will be configured on each site for all production workloads. Correct answer
B: Four 10TB VMFS datastores will be configured on each site for all production workloads.
C: Each 10TB LUN will be configured as a VMFS datastore. Correct answer
D: Two 10TB VMFS datastores will be configured on each site for all DMZ workloads. Correct answer
E: Each 10TB LUN will be configured as an NFS datastore.
F: Seven 10TB VMFS datastores will be configured on each site for all workloads.
Correct Answer:
A. Six 10TB VMFS datastores will be configured on each site for all production workloads.; C. Each 10TB LUN will be configured as a VMFS datastore.; D. Two 10TB VMFS datastores will be configured on each site for all DMZ workloads.
Explanation

Six 10TB VMFS datastores will be configured on each site for all production workloads. This choice is based on the need to distribute production workloads across multiple datastores while ensuring that each datastore is large enough to accommodate the space required by the workloads. Given the average sizes of the virtual machines and the growth and snapshot overhead, six 10TB VMFS datastores would be appropriate for production workloads, ensuring scalability while minimizing the number of LUNs. Each 10TB LUN will be configured as a VMFS datastore. VMFS (Virtual Machine File System) is the standard choice for vSphere environments when using Fibre Channel LUNs. It provides the necessary features, such as concurrency and high-performance access, for production workloads. This option is appropriate given that the storage array uses Fibre Channel for connection and VMFS is the standard file system for such configurations. Two 10TB VMFS datastores will be configured on each site for all DMZ workloads. The DMZ workloads are smaller in number and storage requirements compared to the production workloads, so configuring two 10TB VMFS datastores for DMZ workloads will provide enough capacity while maintaining logical isolation. This approach also minimizes the number of LUNs required to meet the storage growth needs.
