You build an application to serve your current customers. Most of your customers use your service from 3:00 pm to 6:00 pm, so you increase your resource capacity during those times. After 9:00 pm, very few of your customers use your web application, so you decrease your resource capacity after 9:00 pm.
Changing your application's resource capacity to meet changes in demand is an example of which cloud concept?
High availability
Security
Scalability
Utility-based metering
The _____________ cloud service model offers a balance between customization and user control, allowing developers to focus on designing at the application layer while the service handles the administration of the virtual architecture, including the network and operating system.
Infrastructure-as-a-Service
Platform-as-a-Service
Software-as-a-Service
Traditional on-premise
What is a key benefit of Virtualization?
Increased operational cost
Quicker remote connectivity
Reduced network latency
Reduced capital expenditure
What are some of the benefits that the public cloud provides when compared to on-premises data centers? (Choose 3 answers)
Minimizing issues caused by outdated technology
Simplify experimentation with new technology
Compatibility with any application
Potential for exponential growth
Public cloud vendors have a common definition of what aspects of security are the vendor's responsibility and what aspects of security are the end user's responsibility. This is referred to as the Shared Responsibility Model.
Under the Shared Responsibility Model, which of the following would be the end user's responsibility?
Access to the physical datacenter
Creating authentication and authorization mechanisms for a cloud storage service
Availability of a cloud storage service
Operation and administration of the hardware hosting virtual resources
In what way is a private cloud model similar to a public cloud model?
Both private and public cloud models physical hardware are managed by the end users hosting their applications on the hardware.
In both private and public cloud models, the cloud infrastructure is hosted on the premises of a business using it.
Using both private and public cloud will increase a business' capital expenditures to acquire hardware hosting the cloud.
Both private and public cloud models use virtualization to differentiate themselves from traditional on-premise servers.
Moving to the cloud will present many new issues for businesses to consider and anticipate as they migrate from an on-premises environment. Which of the following below is not an issue specific to cloud computing?
Potential increased dependency on the public internet
Restoring service in the event of a server failure
Potential increased risk of cyberattack
Limitations and constraints in platform service level agreements
A ________ cloud deployment model is where a vendor makes available the use of shared infrastructure, including compute, storage and network resources, that can be provisioned on demand and typically accessed over the internet.
private
hybrid
public
community
There are numerous questions a business should consider before it starts planning a migration to the cloud. Which of the following is not a fundamental business question to consider?
How will migration address the current weaknesses in my business?
What technologies will my business utilize in the cloud?
How will migration to the cloud provide benefits to my customers?
How will migration to the cloud help me achieve key business objectives?
What benefit of cloud computing allows you to increase or decrease the power or quantity of resources at any time, without extensive installation or physical processes of provisioning?
Scalability
Economy of Scale
High availability
Utility-based metering
You have been hired as an IT summer intern for a small, but quickly expanding, restaurant chain. The restaurant chain owner wants to expand her online presence by creating a website that will add more online features such as downloadable menus, real-time reservations, online ordering, web-based email, and a possible interactive chat during restaurant hours.
The website will have high access demands from the 4:00 pm to 11:00 pm peak hours, and slower access demands during off-peak hours. The owner does not have any IT experience, and does not want to become involved in the extra work of maintaining IT equipment.
What do you recommend she do?
Implement a hybrid cloud-computing environment.
Implement a private cloud-computing environment.
Implement a matrixed cloud-computing environment.
Implement a public cloud-computing environment.
Migration to the cloud presents numerous potential benefits, but it will not solve all of a business's challenges. Which of the following is not an immediate benefit provided by the cloud?
Improved application performance
Utility-based metering
On-demand resourcing
Economy of scale
The ___________________ model requires no software installation and focuses on design simplicity and ease of use. It offers a minimal level of service customization.
Infrastructure-as-a-Service
Platform-as-a-Service
Software-as-a-Service
Traditional on-premise
Which of the following cloud computing concepts refers to increasing or decreasing compute resources based on demand?
Elasticity
Fault tolerance
Load balancing
High availability
What is the most accurate definition of cloud computing?
Cloud computing is a pool of servers offering compute resources that are designed to be issued exclusively to individual tenants (users and organizations).
Cloud computing is a remote virtual pool of on-demand shared resources offering compute, storage, and network services that can be rapidly deployed at scale.
Cloud computing is a term used to describe virtualized technology.
Cloud computing is a physical pool of compute, storage, and network resources that cannot be accessed over the internet.
The ___________________ cloud service model offers the greatest amount of user customization and control, but requires the greatest amount of user administration including the operating system, but not physical hardware.
Infrastructure-as-a-Service (IaaS)
Platform-as-a-Service (PaaS)
Software-as-a-Service (SaaS)
Traditional on-premise
You have deployed a small web app to your cloud service provider's server. You then deploy a second copy of the app into a second availability zone, and a third copy in a third availability zone.
What are you achieving with these steps?
High availability
Agility
On-demand resourcing
Consumption-based metering
Which service model allows you to configure and customize your environment from the hardware up?
Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
‘Anything’ as a Service (XaaS)
What cloud resource type stores structured data used by cloud applications?
Storage
Compute
Network
Database
A business uses a combination of vendor-managed hardware, such as AWS, Azure, or Google Cloud, and its own hardware on premises to host virtualized resources. This is an example of the ___________ cloud deployment model.
public
