An architect is responsible for the lifecycle management design for a brownfield vSphere-based solution.
The following information has been provided during initial meetings around the new solution:
Existing heterogeneous server hardware will be used to provide the hosting platform.
The available hardware is:
- 10 servers that contain 2 x 20-Core Intel Xeon processors and 512 GB RAM from Vendor A
- 10 servers that contain 2 x 24-Core Intel Xeon processors and 768 GB RAM from Vendor A
- 20 servers that contain 2 x 16-Core AMD EPYC processors and 512 GB RAM from Vendor B
- 10 servers that contain 1 x 24-Core AMD EPYC processors and 256 GB RAM from Vendor B
All of the hardware is currently listed on the VMware Hardware Compatibility List (HCL).
All existing server hardware has 36 months vendor support remaining.
The requirements from the customer are:
REQ001 - The solution must support the hosting of 5,000 workloads spread across two physical sites.
REQ002 - The solution should minimize the number of clusters.
REQ003 - The solution must ensure that there is no impact to service when completing upgrades.
Given the resource requirements needed for the solution, the architect has calculated that all of the existing servers will be required to provide sufficient resources for the new environment. The Intel-based (Vendor A) servers will be deployed to the primary site and both the Intel-based and AMD-based servers (Vendor B) will be deployed to the secondary site.
Which assumption should the architect make to support the lifecycle management of vSphere 8?
An architect is designing a new vSphere solution. The customer has stated that the solution will be used to host different types of applications, some of which have special considerations. The customer has provided the following information in relation to the special considerations:

An architect is discussing recoverability considerations for a new vSphere solution as part of a requirements workshop. The customer has informed the architect that the company policy is to not perform backups of ESXi hosts due to their selected backup software not supporting the ESXi software. In the past, when hosts have experienced failures, the hosts have been reinstalled from the VMware provided ESXi image and manually configured by an administrator. The customer asks the architect to design a solution that will reduce the manual effort required by the administrator to return a failed host to service.
What could the architect include in the design to meet the customer's request?
An architect is designing an upgrade to an existing vSphere environment. The project has been created to provide options for enabling growth and scalability, without increasing the data center footprint.

The existing vSphere environment uses an external fibre attached storage array for the vSphere environment
The storage array is connected via 4 Gbps fibre cards host bus adaptors (HBAs)
The storage array does not support VMware Storage APIs—Data Protection (VADP)
The architecture must support scaling virtual machines CPU, memory, and storage
The environment will grow by an additional 20% virtual machines year over year
Only two additional racks of equipment can be provisioned
Which design choice will meet these requirements?
An architect is discussing the design of a vSphere solution with a customer. The following requirements have been defined for the solution:

Which two implications should the architect include in the design in relation to this design decision? (Choose two.)
An architect is documenting the design for a new multi-site vSphere solution. The customer has informed the architect that the workloads hosted on the solution are managed by application teams who must perform a number of steps to return the application to service following a failover of the workloads to the secondary site. These steps are defined as the Work Recovery Time (WRT). The customer has provided the architect with the following information about the workloads, including the recovery time objective (RTO) and recovery point objective (RPO):
Critical workloads have a WRT of 12 hours
Production workloads have a WRT of 24 hours
Development workloads have a WRT of 24 hours
All workloads have an RPO of 4 hours
Critical workloads have an RTO of 1 hour
Production workloads have an RTO of 12 hours
Development workloads have an RTO of 24 hours
The customer has also confirmed that production and development workloads are managed by the same team and the disaster recovery solution will not begin the recovery of the development workloads until all critical and production workloads have been recovered at the secondary site.
Which three statements would the architect document as the maximum tolerable downtime (MTD) for workloads within the design? (Choose three.)

The solution must support physical segregation of management and workload traffic.
Any traffic from virtual infrastructure-level operations (such as migrations of workloads between hosts within a cluster) must not impact any workload.
The solution should react to any substantial impact of physical network traffic to ensure workload traffic is unaffected.
In response to this requirement, the architect makes the following logical design decisions:
The solution will separate vSphere management traffic from all other network traffic.
The solution will ensure that all replication and vMotion traffic will be separated from all other traffic.
The solution will separate workload traffic from all other network traffic.
The customer has a hardware standard for physical VMware ESXi host servers that includes 6 x 10 GbE network.

An architect is creating the design for a vSphere platform that will be used as the target for a migration from multiple legacy vSphere platforms that are being decommissioned. The customer has provided the following information:
Each legacy platform has its own set of virtual machine templates stored in OVF format.
All of the templates need to be migrated to the new platform.
After migration, the templates should be centralized into a single location.
The templates must be accessible to all clusters in the new platform vCenter instance.
Any new templates added to the central location must be automatically available to all clusters.
Administrators must be able to deploy new virtual machines directly from the template instances.
The customer also confirmed that after the migrations are complete, the new platform will be the only vSphere solution available.
Which design choice should the architect evaluate in the logical design for the storage and management of virtual machine templates?
