You are a virtualization consultant at a company that develops its own inhouse website trading
systems. The new website will be deployed in a vSphere 5 platform, which consists of two clusters
and four ESXi hosts (one for each project—the SDLC hosts—for all levels of testing and
development prior to production deployment).
The production cluster has been configured for fully automated DRS and VMware HA. During the
SDLC, the website platform was developed on a single development ESXi host inside a single
VLAN. The system was successfully tested within the SDLC ESXi hosts and then deployed to the
production cluster in a single vApp and a single VLAN.
Following a successful midweek, the new application starts to show signs of latency. Suddenly
several applications across the cluster are being impacted by network latency issues. Metrics are
collected and show that the amount of network traffic between the database and application
servers of the new website platform are at 96% utilization on the physical switch links between
ESXi hosts in the production cluster. What should you do?

A.
Recommend that the website platform be fixed and removed from the production system.

B.
Create a DRS affinity rule to ensure that the database and applications servers stay on the
same ESXi host and do not traverse the physical network when communicating.

C.
Configure Network I/O Control to ensure that the network latency is alleviated between the
database and applications servers.
