Advanced Design VMware vSphere 7.x Questions and Answers

Question 1

An architect is designing a vSphere environment for a customer based on the following information:

  • The vSphere cluster will have three hosts only due to budget considerations.
  • A database cluster (node majority) consisting of three virtual machines will be running on the vSphere cluster.

Which two recommendations can the architect make so that the customer achieves the highest level of

application availability while taking into consideration operational resiliency? (Choose two.)

Options:

A.

Create VM-VM anti-affinity rules

B.

Set das.respectvmvmantiaffinityrules to false

C.

Create VM-Host anti-affinity rules

D.

Disable vSphere HA during maintenance

E.

Set das.ignoreinsufficienthbdatastore to true

Question 2

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 3

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
