Module 2 - Lesson 1&2 - Pre Quiz Virtualisation and Benefits

What is a benefit of virtualization in terms of cost savings?

• Cost savings through hardware consolidation

• Higher energy consumption

• No impact on cost

• Increased hardware costs

What is the benefit of virtualization in terms of resource utilization?

• Increased cost of physical resources

• Better utilization of physical resources

• Decreased efficiency of physical resources

• No impact on physical resources

What is a benefit of virtualization in terms of scalability?

• Limited flexibility in resource allocation

• Increased security measures

• Higher cost of hardware maintenance

• Easier allocation and reallocation of resources

What is the benefit of virtualization in terms of testing and development?

• Limited flexibility and scalability

• Increased hardware costs and resource utilization

• Isolated testing environments and quick environment setup

• Slower testing and development process

What is a benefit of virtualization in terms of simplified management?

• Increased hardware costs

• Centralized management of multiple virtual machines

• Decreased flexibility in managing resources

• Limited ability to scale virtual machines

What is the purpose of a virtual switch in a virtualization environment?

• Allocating CPU resources to virtual machines

• Managing storage for virtual machines

• Handling network traffic between virtual machines

• Creating isolated environments for VMs

In vSphere, how is memory managed for virtual machines?

• Each VM is allocated a fixed amount of physical memory

• Memory is dynamically shared among VMs based on demand

• vSphere does not manage memory for virtual machines

• VMs directly access physical memory without intervention from vSphere

How does vSphere contribute to the scalability of a virtualized environment?

• Allocates a fixed number of CPUs to each VM

• Manages memory statically, without adaptation to changing demands

• Dynamically adjusts resources like CPU, memory, network, and storage based on workload

• Limits the number of VMs that can run concurrently
