QUESTION 8

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?

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 9

An architect is tasked with designing a new VMware software-defined data center (SDDC) solution for an
online retail customer who has a primary and secondary data center as well as 10 distribution hubs.
The customer has provided the following business requirements to help inform the design:
The solution must support the running of up to 1,000 concurrent virtual machines across the primary and
secondary data center.
The solution must support the running of up to 20 concurrent virtual machines in each distribution hub.
The solution must support the separation of management and lines-of-business application virtual machines.
All management components (including directory services, backup, automation, operations and logging)
must be deployed to the primary data center.
All virtual infrastructure components must have redundancy of N+1.
All sites are connected to each other using a wide area network that has multiple diversely routed links.
The solution should support a monthly uptime target of 99.9%.
The recovery time objective (RTO) for the solution must be four hours.
The recovery point objective (RPO) for the solution must be 24 hours.

–
Steps to confirm the web server is operating correctly will take 15 minutes after the application server is online. An
application server
–
Steps to confirm application server integrity will take 15 minutes after the database is online. A database server
-The database server will be managed by a database administrator, with an agreed service-level agreement (SLA) to
restore and validate database services within one hour.

vMotion, vSAN and Fault Tolerance traffic, and the second one for virtual machine traffic
D. Use a NIC teaming policy based on the physical NIC load
