Para-virtualization

Question 11

_____ virtualization allows multiple users to simultaneously access the same application installed on a central server.

Answer 11

Application Virtualization

Question 12

What type of virtualization is used to pool physical storage from multiple, often separate,
network storage devices into one logical storage device that is centrally controlled?

Answer 12

Storage Virtualization

Question 13

What are the common applications of virtualization technologies? (6)

Answer 13

1. Development and Testing
2. Training
3. Server Consolidation
4. Load Balancing
5. Server Pooling
6. Disaster Recovery

Question 14

What type of hypervisor has the virtualization software installed directly on the machine
hardware?

Answer 14

Type 1 Hypervisor
(Bare-metal)

Question 15

What type of hypervisor is installed onto an operating system?

Answer 15

Type 2 Hypervisor
(Hosted)

Question 16

What is a disadvantage of a Bare-Metal hypervisor?

Answer 16

limited hardware support

(because the hypervisor usually has limited built-in device drivers)

Question 17

What is the advantages of a Type 2 hypervisor?

Answer 17

Better hardware compatibility

(OS is responsible for the hardware drivers instead of the hypervisor.)

What are the four main benefits of virtualization?

Answer 18

1. Infrastructure simplification
2. Reduction in Total Cost of Ownership (TCO)
3. Environmental Issues
4. Improved Responsiveness

Question 19

A Total Cost of Ownership (TCO) benefit increases a business’s return on investment (ROI) and is achieved by __________, __________, and _________.

Answer 19

1. Increased server utilization
2. Decreased management infrastructure costs
3. Lowered costs to deploy new environments

Question 19

(True/False) Server consolidation allows one server to virtually host many once-dedicated servers that may have been underutilized in their stand-alone state.

Answer 19

True

Question 20

Name the three environmental issues that virtualization addresses.

Answer 20

1. Reduce electrical energy consumption
2. Decreased cooling requirements
3. Decreased physical space requirements

Question 21
