What feature does not belong in a private cloud?
-
Metered billing
-
Self-service portal
-
Dial-home support
-
Rapid elasticity
AI Explanation
To answer this question, we need to understand the features typically associated with a private cloud.
A private cloud is a cloud computing model where resources are dedicated to a single organization. It provides similar benefits to a public cloud, such as scalability, flexibility, and self-service, but with added control and security.
Let's go through each option to understand why it does or does not belong in a private cloud:
Option A) Metered billing - This option can be present in a private cloud. Metered billing refers to the practice of measuring resource usage and charging users based on that usage. It can help organizations track and manage costs.
Option B) Self-service portal - This option is commonly associated with private clouds. A self-service portal allows users to provision and manage resources on-demand without the need for manual intervention from IT administrators.
Option C) Dial-home support - This option does not typically belong in a private cloud. Dial-home support refers to a feature where devices automatically report their status and performance to a central support system. This feature is more commonly associated with traditional IT infrastructure rather than a private cloud.
Option D) Rapid elasticity - This option is commonly associated with private clouds. Rapid elasticity refers to the ability to quickly scale resources up or down based on demand. It allows organizations to dynamically allocate and deallocate resources as needed.
Based on the above explanations, the correct answer is option C) Dial-home support. This option does not typically belong in a private cloud.
Amazon Web Services is which type of cloud computing distribution model?
-
Software as a Service
-
Platform as a Service
-
Infrastructure as a Service
-
None of the above
To answer this question, you need to understand the different types of cloud computing distribution models.
A. Software as a Service (SaaS): This model provides software applications over the internet on a subscription basis. Users do not have to worry about managing the underlying infrastructure or the software itself. Examples of SaaS providers include Salesforce, Dropbox, and Google Workspace.
B. Platform as a Service (PaaS): This model provides a platform for developing, testing, and deploying applications. PaaS providers offer a complete development environment, including operating systems, programming languages, and development tools. Examples of PaaS providers include Heroku, Microsoft Azure App Service, and Google App Engine.
C. Infrastructure as a Service (IaaS): This model provides virtualized computing resources over the internet. It includes virtual machines, storage, and networking capabilities. Users have control over the operating system and applications running on the infrastructure. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
D. None of the above: This option implies that Amazon Web Services (AWS) does not fall into any of the mentioned cloud computing distribution models.
To determine the correct answer, you need to identify which distribution model AWS falls into.
The correct answer is:
C. Infrastructure as a Service (IaaS)
Explanation: Amazon Web Services (AWS) is a prominent example of an IaaS provider. It offers a wide range of virtualized computing resources, such as EC2 instances, storage services like S3, and networking services like VPC. Users can provision and manage these resources as needed, providing them with the flexibility and control over their infrastructure.

Option C) Symantec - This option is incorrect because there is no recent news or announcement about Symantec shutting down its cloud storage service.
Option D) Iron Mountain - This option is correct because Iron Mountain recently announced the closure of its cloud storage service. This decision was made to focus on their core business of physical data storage and management.
Therefore, the correct answer is Option D) Iron Mountain.
What is Cloud Foundry?
-
A factory that produces cloud components
-
VMware-led closed source PaaS
-
An industry wide PaaS initiative
-
VMware-led open source PaaS
AI Explanation
To answer this question, you need to understand what Cloud Foundry is.
Option A) A factory that produces cloud components - This option is incorrect because Cloud Foundry is not a physical factory that produces cloud components. Rather, it is a platform that allows developers to deploy and run applications on cloud infrastructure.
Option B) VMware-led closed source PaaS - This option is incorrect because Cloud Foundry is not closed source. While VMware has been involved in the development of Cloud Foundry, it is an open-source project with contributions from various organizations.
Option C) An industry-wide PaaS initiative - This option is partially correct. Cloud Foundry is indeed an industry-wide Platform as a Service (PaaS) initiative. It was initially developed by VMware and is now governed by the Cloud Foundry Foundation, which includes various companies and organizations.
Option D) VMware-led open-source PaaS - This option is correct. Cloud Foundry is an open-source PaaS initiative that was initially led by VMware. It allows developers to deploy and run applications on cloud infrastructure.
The correct answer is Option D. This option is correct because Cloud Foundry is an open-source PaaS initiative led by VMware.

Which of these services is not Platform as a Service?
-
Force.com
-
Microsoft Azure
-
Amazon EC2
-
Joyent
To solve this question, the user needs to know the different types of cloud computing services. The three main types of cloud computing services are Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS). SaaS offers software applications over the Internet, IaaS offers virtualized computing resources over the Internet, and PaaS provides a platform for developers to build, test, and deploy applications over the Internet.
Now, let's go through each option and explain why it is right or wrong:
A. Force.com: This option is a PaaS service offered by Salesforce.com. Force.com provides a platform for developers to build and deploy web applications and mobile apps over the Internet. Hence, this is a Platform as a Service.
B. Microsoft Azure: This option is a cloud computing platform and Infrastructure as a Service (IaaS) service offered by Microsoft. Azure provides virtualized computing resources over the Internet, such as virtual machines (VMs) and storage. Thus, this is an Infrastructure as a Service.
C. Amazon EC2: This option is also an IaaS service offered by Amazon Web Services (AWS). Amazon EC2 provides virtualized computing resources over the Internet, such as VMs and storage. Thus, this is an Infrastructure as a Service.
D. Joyent: This option is a cloud computing company that offers Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) services. Joyent provides virtualized computing resources over the Internet, as well as a platform for developers to build and deploy applications over the Internet. Hence, this is both Infrastructure as a Service and Platform as a Service.
Therefore, the answer is: C. Amazon EC2, since it is not a Platform as a Service, but an Infrastructure as a Service.
