Advanced Design VMware vSphere 7.x Questions and Answers

Question 1

During a transformation project kick-off meeting, an architect highlights specific areas on which to focus while developing the new conceptual design.

Which two of the listed statements are business requirements? (Choose two.)

Options:

A.

The project should use the existing storage devices within the data center

B.

Sites must support a network latency of less than 12 ms round-trip time (RTT)

C.

The solution must allow data replication between sites

D.

There is no budget specifically assigned for disaster recovery

E.

There must not be a single point of failure for the virtual infrastructure

Question 2

An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.

The platform has recently commissioned new hosts to update the development cluster.

The development cluster host configuration is:

  • 4 ESXi hosts with 2 sockets × 16 cores
  • 512 GB RAM divided evenly between sockets
  • There is no resource contention

The benchmarking cluster host configuration is:

  • 8 ESXi hosts with 2 sockets × 8 cores
  • 256 GB RAM divided evenly between sockets
  • There is no resource contention

The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.

What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

Options:

A.

The database tier breaches a single NUMA node boundary for the benchmarking cluster

B.

The database tier breaches a single NUMA node boundary for the development cluster

C.

The development cluster can support a lower %Ready time per vCPU

D.

The development cluster has more available RAM per host

Question 3

An architect is preparing a design for a company planning digital transformation. During the requirements gathering workshop, the following requirements (REQ) and constraints (CON) are identified:

  • REQ01 The platform must host different types of workloads including applications that must be compliant with internal security standard.
  • REQ02 The infrastructure must initially run 100 virtual machines.
  • REQ03 Ten of the virtual machines must be compliant with internal security standard.
  • REQ04 The internal security standard specifies logical network separation for in-scope applications.
  • CON01 The customer has already purchased the licenses as part of another project.
  • CON02 The customer has five physical servers that must be reused.

Additionally, based on resource requirements, four physical servers will be enough to run all workloads. Which recommendation should the architect make to meet requirements while minimizing project costs?

Options:

A.

Use Network I/O Control to ensure the internal security zone has higher share value

B.

Purchase additional servers and plan separate, isolated clusters for workloads that must be compliant with internal security

C.

Use a single cluster and ensure that different security zones are separated at least with dedicated VLANs and firewall

D.

Use a single cluster and configure DRS anti-affinity rules to ensure internal security compliant virtual machines cannot migrate between ESXi hosts.
