Question 1

Q: Where are public cloud services hosted?

Answer 1

A: On hardware resources at the Cloud Service Provider’s (CSP) location.

Question 2

Q: Who can share the physical resources in a public cloud?

Answer 2

A: Any customer of the CSP.

Question 3

Q: What types of services do CSPs provide?

Answer 3

A: Cloud services such as storage space, applications, compute capacity, or network functions.

Question 4

Q: What is one characteristic of the resources in a public cloud?

Answer 4

A: They are shared among multiple customers.

Question 5

Q: Can customers directly access the hardware in a public cloud?

Answer 5

A: No, customers cannot access the hardware directly.

Question 6

Q: What do customers rely on from CSPs in a public cloud?

Answer 6

A: Security measures to protect data and resources.

Question 7

Q: Does reliance on CSP security measures eliminate customer responsibility for data security?

Answer 7

A: No, customers still have responsibility for their data security.

Question 8

Q: What is the main concern for customers using a public cloud?

Answer 8

A: The security of their data and compliance with industry standards.

Question 9

Q: What is a key consideration when selecting a CSP?

Answer 9

A: The adequacy of their security measures.

Question 10

Q: What should customers check regarding security in the SLA?

Answer 10

A: Security requirements and terms of agreement.

Question 11

Q: What is one requirement that may be included in the SLA?

Answer 11

A: Encryption of all data in transit or storage.

Question 12

Q: What defines a private cloud service?

Answer 12

A: It is hosted on hardware resources used exclusively by a single organization.

Question 13

Q: Where can the hardware for a private cloud be located?

Answer 13

A: In a CSP’s data center or the organization’s own data center.

Question 14

Q: What is a key characteristic of private cloud hardware usage?

Answer 14

A: No other organization can use the hardware for their own cloud.

Question 15

Q: What advantage does a private cloud provide in terms of configuration?

Answer 15

A: Greater control over the exact configuration of the hardware used.

Question 16

Q: What is a common motivation for deploying a private cloud on-premises?

Answer 16

A: The need to keep sensitive data on-site.

Question 17

Q: What technology is commonly used in traditional data centers?

Answer 17

A: Virtualization.

Question 18

Q: Does virtualization provide flexibility in hardware interaction?

Answer 18

A: Yes, it allows for flexible service deployment.

Question 19

Q: How are configurations in virtualization related to physical hardware?

Answer 19

A: They are closely tied to the underlying physical hardware.

Question 20

Q: What is a key advantage of a private cloud over traditional data centers?

Answer 20

A: Greater isolation and control over resources.

Question 21

Q: Can traditional data centers use cloud models?

Answer 21

A: Yes, but they may not provide the same level of service isolation as private clouds.

Question 22

Q: What is a potential limitation of virtualization in a traditional data center?

Answer 22

A: Dependence on the physical hardware for service configurations.

Question 23

Q: How is a cloud more abstracted from physical hardware?

Answer 23

A: Through a cloud API layer of communication managed by virtualization software.

Question 24

Q: What type of approach does private cloud security require?

Answer 24

A: A traditional approach to securing a network perimeter.

Question 25

Q: What components need to be secured in a virtual environment?

Answer 25

A: The hypervisor, virtual machines (VMs), and physical hosts.

Question 26

Q: How should systems be isolated on physical hosts?

Answer 26

A: By security zone, ensuring low-security systems are not on the same machine as high-security systems.

Question 27

Q: Why is it important to segment virtual systems from physical hosts?

Answer 27

A: To prevent guest machines from accessing the physical host’s systems and configurations inappropriately.

Question 28

Q: What is a hybrid cloud?

Answer 28

A mix of both public and private cloud components, or a combination of cloud and traditional on-prem services.

Question 29

Q: Why do some organizations opt for a hybrid cloud model?

Answer 29

A: Not every application, data set, or service is suitable for the cloud.

Question 30

Q: What is the most common cloud deployment model?

Answer 30

A: Hybrid cloud model.

Question 31

Q: Are most organizations fully committed to the cloud?

Answer 31

A: Relatively few organizations are ready or able to commit fully to the cloud.

Question 32

Q: What are the two main components of a hybrid cloud?

Answer 32

A: Public cloud and private cloud.

Question 33

Q: What kind of services can be included in a hybrid cloud model?

Answer 33

A: Both cloud services and traditional on-premises services.
