Application performance test cases are most accurate if based on .
Answer(s): A
The best validation is to place a platform under a typical test of what it will be faced with in the field--for example, having a simulated number of users go through a workflow (perhaps a website).

You are a VMware consultant for a large enterprise running VMware vSphere 4.1. You are reviewing the upgrade documentation created to take the company to version 5.X of the software. The upgrade has several requirements, including the following:Minimize the impact to the business applications Do a full rollback, if required, for any issues not foreseen by the project team You notice in the documentation that the upgrade to VMFS 5 is mentioned as being nondisruptive and having zero impact on the technical solution. Is this technically correct?

During an upgrade of VMware vSphere 4.1 to vSphere 5.0, several virtual machines appeared to have lost network configuration. What is the possible cause of the issue?
Answer(s): C
This can be experienced when migrating from a virtual machine hardware level and have an old version of VMware tools installed. The guest operating system may not understand the hardware and may create or lose information such as the MAC address and network settings. By upgrading VMware tools first and then upgrading the hardware the correct drivers and software are present for a non-impacting upgrade.
