The Cloud

Which of the following is a key benefit of cloud computing in terms of operational costs?

• It requires less energy consumption than traditional IT infrastructure.

• It uses resources more efficiently and reduces inconsistent availability and high operational costs.

• It increases the need for physical hardware and data centers.

• It eliminates the need for virtual machines.

What is the primary function of Platform as a Service (PaaS) in cloud computing?

• To provide a remote storage platform for data access.

• To allow users to buy, develop, test, deploy, and manage software applications.

• To monitor software applications and notify personnel when performance issues arise.

• To offer communication services such as VoIP and VPN services.

Which service would be the best fit for an organization that needs to store large amounts of data, allowing easy access from various devices?

• Storage services

• Communications services

• Platform as a Service (PaaS)

• Software as a Service (SaaS)

  How does the cloud enable data center/server consolidation?

• By allowing servers to be run individually without virtual machines.

• By maintaining separate infrastructure for each server.

• By eliminating the need for virtualization altogether.

• By moving servers from current data centers to the cloud and hosting virtual machines on a virtualization host.

What does the concept of multi-tenancy in cloud computing allow organizations to do?

• It allows multiple organizations to use the same application while keeping their data and configurations separate.

• It provides a single organization with multiple cloud service providers.

• It ensures that all users share the same server infrastructure, lowering costs.

• It helps organizations to separate and manage their on-premises data and cloud data.

What is a key responsibility of clients when using the pay-as-you-go cloud subscription model?

• The cloud provider automatically deprovisions resources when not in use.

• The client is responsible for ensuring that resources are provisioned only when needed, to avoid waste.

• The client is only billed for infrastructure, but not for software usage.
  
  

• The client must pay upfront for all cloud services for the year.

Which type of expenditure covers the costs of servers, networking equipment, and other physical assets used in a traditional data center?

• Operating Expenses (OpEx)

• Cloud computing costs

• Capital Expenditures (CapEx)

• Subscription-based cloud billing

In a traditional data center, which of the following would be categorized as an Operating Expense (OpEx)?

• The cost of acquiring servers and networking equipment

• The cost of electricity and staff to manage the servers

• The cost of building and maintaining data center infrastructure

• The cost of acquiring real estate for a new data center

Which of the following best describes scalability in the context of cloud computing?

• The ability of an application to function as its size or volume changes to meet user needs.
  
  

• The ability to keep all systems operating continuously without any failure.
  
  

• The ability to store large volumes of data without impacting performance.
  
  

• The ability to automatically upgrade hardware without manual intervention.

Why is elasticity an important feature of cloud computing?

• It helps ensure that resources are always over-provisioned.

• It automatically adjusts the number of users accessing a service to meet demand.

• It allows resources to be automatically added or removed to match changing workloads.

• It limits the amount of resources that can be used at any given time.
