Sertification Preparation - 1

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• Minimizing issues caused by outdated technology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
