• Question 82:

  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?

  A. The different processor architectures across both sites will remediate against a shared vSphere Lifecycle Manager baseline.

  A. Only certain commands can be executed in the sandboxed shell
  B. Only administrative accounts can access the sandbox shell

• Question 84:

  Capacity planning will ensure that the environment does not exceed 70% of peak-average utilization on deployment.

  CPU purchases will favor clock speed and last level cache over cores per socket.

  Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days.

  Path Selection policy will be set to round robin and set to switch paths with every SCSI command.

  vCPU to pCPU ratio may not exceed 5:1. What are three considerations when designing for performance? (Choose three.)

  A. Path Selection policy will be set to round robin and set to switch paths with every SCSI command.
  B. vCPU to pCPU ratio may not exceed 5:1.
  C. Capacity planning will ensure that the environment does not exceed 70% of peak- average utilization on deployment.
  D. All ESXi hosts must have four paths to the storage array.
  E. CPU purchases will favor clock speed and last level cache over cores per socket.
  F. Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days.
  B. vCPU to pCPU ratio may not exceed 5:1.
  E. CPU purchases will favor clock speed and last level cache over cores per socket.
  F. Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days.

• Question 85:

  What is an example of a performance design quality?

  A. The solution must scale to meet spikes in CPU demand.
  B. The solution must provide 40 physical CPU cores and 20 TB of physical memory.
  C. The solution must support applications with a maximum tolerable downtime (MTD) of four hours.
  D. The solution must support applications with 1,000 transactions per second (TPS).
  A. The solution must scale to meet spikes in CPU demand.

• Question 86:

  An architect is discussing the design of a vSphere solution with a customer. The following requirements have been defined for the solution:

  The solution must provide data encryption at rest

  The solution must provide the ability to reduce the amount of storage consumed from duplicate data

  The solution must minimize the amount of resources consumed by the encryption process.

  The architect has made a design decision that VM Encryption will be used to meet these requirements.

  Which two implications should the architect include in the design in relation to this design decision? (Choose two.)

  A. Encryption is a CPU-intensive feature. Resource Pools should be used to assign shares to the encrypted VMs.
  B. When data is encrypted by the storage device, the effectiveness of de-duplication on the storage will be unaffected.
  C. Encryption is a CPU-intensive feature. The ESXi hosts should use the AES-NI BIOS setting to improve the performance of encryption and reduce CPU utilization.
