1. True or false: Virtualization is a tool for testing and development.
2. True or false: Blade servers are constantly gaining share in the enterprise market but they are not as cost-effective as rack-mounted servers for smaller deployments.
3. True or false: Virtualization can ease backup, reduce administrative demands and improve security at the desktop level.
4. True or false: Low server utilization can impair your ability to expand your infrastructure, your budget to buy new hardware and your resources to deploy it.
5. True or false: Virtualization can ease backup, reduce administrative demands and improve security at the desktop level.
6. True or false: Incrementally introducing blades into the server room along with legacy hardware creates operational challenges.
7. True or false: Virtualization can help defray the cost of a data center expansion.
8. True or false: When you're planning a virtualized infrastructure project, the first thing you need to do is evaluate available products.
9. True or false: Blades make it easier to implement network-attached storage.
10. True or false: An application running within a virtual machine uses fewer resources than one running on a physical machine.
How did you do?
1. True or false: Virtualization is a tool for testing and development.
Answer: True.
A single physical server can host dozens of virtualized development environments, where you can safely run and test several applications at once without impacting your mission-critical production environment.
2. True or false: Blade servers are constantly gaining share in the enterprise market but they are not as cost-effective as rack-mounted servers for smaller deployments.
Answer: False.
Although that was true originally, newer products are being developed with the midmarket in mind. For example, smaller footprint, lower up-front investment and more user-friendly power adapters are among the promises of HP's BladeSystem c3000.

3. True or false: Virtualization can ease backup, reduce administrative demands and improve security at the desktop level.
Answer: True.
With the right technologies, you can host desktops in virtual machines, running on centralized servers in your data center.
4. True or false: Low server utilization can impair your ability to expand your infrastructure and your budget to buy new hardware.
Answer: True.
All that wasted space wastes resources. Furthermore, according to analyst Tony Iams, servers in many companies typically run at 15-20% of their capacity, which may not be a sustainable ratio in the current economic environment.
5. True or false: Blade servers and server virtualization are two different and incompatible approaches to server consolidation.
Answer: False.
In fact, an approach that combines both blades and virtualization will do more than consolidate space by increasing efficiency and security.
6. True or false: Incrementally introducing blades into the server room along with legacy hardware creates operational challenges.
Answer: False.
Actually, introducing blades into the server room isn't any more likely to create any more challenges than running rack-mounted and tower-based servers in the same room. Read our tip to learn more about towers, racks and blades
7. True or false: Virtualization can help defray the cost of a data center expansion.
Answer: True.
This becomes an important selling feature for virtualization when you consider that the average rack of servers or storage takes up seven square feet.
8. True or false: When you're planning a virtualized infrastructure project, the first thing you need to do is evaluate available products.
Answer: False.
The first thing you need to do is take stock. A detailed inventory of your entire computing environment will identify your requirements.
9. True or false: Blades make it easier to implement network-attached storage.
Answer: True.
It's easier to connect network storage to a blade than to individual servers.
10. True or false: An application running within a virtual machine uses fewer resources than one running on a physical machine.
Answer: False.
In fact, given the same workload, an application running in a virtual machine requires more resources than one on a physical machine.
