IGCSE ICT Cloud Computing Quiz

What are two advantages of cloud computing?

• Inflexibility and slow performance

• Limited storage and high cost

• Security risks and lack of control

• Scalability and cost savings

Explain the benefits of scalability and flexibility in cloud computing.

• Scalability allows for easy resource adjustment, while flexibility enables the use of different services and resources based on specific needs.

• Scalability does not allow for resource adjustment, while flexibility restricts the use of different services and resources based on specific needs.

• Scalability makes it difficult to adjust resources, while flexibility limits the use of different services and resources based on specific needs.

• Scalability only allows for resource adjustment in one direction, while flexibility does not enable the use of different services and resources based on specific needs.

What are two disadvantages of cloud computing?

• Security concerns and dependency on internet connectivity

• Limited storage space and slow processing speed

• High cost and lack of control over data

• Incompatibility with certain software and hardware

Discuss the potential risks of data security and privacy in cloud computing.

• High cost of cloud services

• Physical security of servers

• Limited access to data from different devices

• Unauthorized access, data breaches, data loss, lack of control over data storage and management

What are two types of cloud computing services?

• Desktop as a Service (DaaS) and Security as a Service (SECaaS)

• Platform as a Service (PaaS) and Database as a Service (DBaaS)

• Hardware as a Service (HaaS) and Network as a Service (NaaS)

• Infrastructure as a Service (IaaS) and Software as a Service (SaaS)

Explain the differences between SaaS and IaaS.

• SaaS is used for virtual reality gaming, while IaaS is used for online shopping.

• SaaS is software hosted on the cloud, while IaaS provides infrastructure such as servers and storage.

• SaaS is a type of pasta, while IaaS is a type of sauce.

• 1. Using Google Drive for storing and accessing files. 2. Using Netflix for streaming movies and TV shows.

Explain how companies use cloud computing for storage and collaboration.

• Using physical servers and restricting access to files to only one location

• Storing data on remote servers and allowing employees to access and work on the same files from different locations

• Storing data on local hard drives and manually transferring files between employees

• Storing data on floppy disks and sharing them through email
