Ans: (1) VPCs are provisioned in a logically isolated part of a shared public cloud
(2) The VPC infrastructure is owned, managed, and operated by the public cloud service provider
3. If an organization needs to run a highly sensitive and mission critical application with unpredictable performance and capacity requirements, which of the following models would best meet its requirements?
Ans: Hybrid Cloud
Module 4 – Graded Quiz
1. Is it possible to run completely different operating systems on Virtual Machines (VMs) that are on a single host? If yes, what makes this possible?
Ans: Yes, Virtualization makes it possible— to have VMs, running different operating systems, on a single host.
2. Which of these scenarios is ideal for the use of bare metal servers, as opposed to virtual servers? Select two.
Ans: (1) CPU and I/O intensive workloads correct
(2) Huge performance and strict security and compliance requirements correct
3. Subnets are the main area where security is implemented in the cloud. What is used to provide security at the virtual instance level in subnets?
Ans: Security Groups or SGs
