Mastering Cloud Computing Concepts

What are the three main cloud service models?

• DaaS, FaaS, CaaS

• IaaS, SaaS, DBaaS

• PaaS, SaaS, XaaS

• IaaS, PaaS, SaaS

Define Infrastructure as a Service (IaaS).

• Infrastructure as a Service (IaaS) is a cloud computing service model that provides virtualized computing resources over the internet.

• Infrastructure as a Service (IaaS) is a type of data storage service.

• IaaS is a software development platform for building applications.

• Infrastructure as a Service (IaaS) is a physical server rental service.

What is Platform as a Service (PaaS) used for?

• PaaS is primarily used for data storage and backup.

• PaaS is used for developing, testing, and deploying applications in a cloud environment.

• PaaS is a type of hardware used for networking.

• PaaS is mainly focused on providing physical servers for businesses.

Explain Software as a Service (SaaS) with an example.

• An example of SaaS is Microsoft Word, which is installed on local computers.

• An example of SaaS is Adobe Photoshop, which requires a software download.

• An example of SaaS is a traditional desktop application that runs offline.

• An example of SaaS is Google Workspace, which provides applications like Gmail, Google Docs, and Google Drive accessible online.

Identify the four primary cloud deployment types.

• public cloud, private cloud, hybrid cloud, community cloud

• managed cloud

• secure cloud

• virtual cloud

What is the difference between public and private clouds?

• Public clouds are shared and accessible over the internet; private clouds are dedicated to one organization.

• Public clouds are only for government use; private clouds are for personal data.

• Public clouds are more secure than private clouds; private clouds are less accessible.

• Public clouds require physical servers on-site; private clouds are hosted remotely.

Describe a hybrid cloud environment.

• A hybrid cloud environment does not allow data sharing between clouds.

• A hybrid cloud environment integrates private and public clouds, allowing data and applications to be shared between them.

• A hybrid cloud environment only uses private cloud resources.

• A hybrid cloud environment is solely based on public cloud services.

What are the key benefits of using cloud computing?

• Key benefits of using cloud computing include scalability, cost efficiency, accessibility, and enhanced collaboration.

• Limited data storage

• Increased hardware requirements

• Reduced internet connectivity needs

List three common security measures in cloud computing.

• Data backup, firewall protection, user training

• Network monitoring, physical security, software updates

• Malware scanning, password complexity, incident response plans

• Data encryption, access control, regular security audits

What is data encryption and why is it important in the cloud?

• Data encryption is the process of deleting unnecessary files in the cloud.

• Data encryption is only necessary for on-premises data storage.

• Data encryption is a method of increasing internet speed in the cloud.

• Data encryption is the process of converting information into a secure format to protect it from unauthorized access, and it is important in the cloud to ensure the confidentiality and integrity of sensitive data.
