• To manage and store the data used by the ERP system

• To process the user inputs and interact with the database tier

• To provide a user-friendly interface for interacting with the ERP system

• To distribute the processing load and ensure scalability

Which tier in ERP architecture contains the core business logic and application processing?

• Web Tier

• Application Tier

• Presentation Tier

• Data Tier

What is the main goal of cloud architecture?

• To manage and distribute various components of the software across different layers

• To offer a platform allowing developers to build, deploy, and manage applications

• To eliminate the need for users to install, maintain, or update the software

• To provide efficient, scalable, and reliable computing services

Which cloud service model offers virtualized computing resources over the internet, including virtual machines, storage, and networking?

• Software as a Service (SaaS)

• Private Cloud

• Infrastructure as a Service (IaaS)

• Platform as a Service (PaaS)

What is a key benefit of cloud computing?

• Reduced capital and operating expenditures for IT equipment and support personnel

• Dynamic scalability available on demand

• No need to install anything on the user’s computer

• Promotes green computing environment as servers in cloud run on clean energy

What is a limitation of cloud computing?

• Accessed from everywhere, as long as you have an Internet connection

• Pay for subscription, not for licenses and upgrades

• Vulnerability

• Guaranteed reliability

What is a key component of cloud architecture that provides virtual networks, load balancers, and other networking components to connect and manage communication between different cloud resources?

• Cloud Service Models

• Networking

• Compute Resources

• Storage

Which cloud deployment model combines public and private clouds, allowing data and applications to be shared between them?

• Public Cloud

• Private Cloud

• Hybrid Cloud

• Cloud Infrastructure

What is a benefit of three-tier architecture in ERP systems?

• Easier to increase reliability of a system by implementing multiple levels of redundancy

• No maintenance fees for software or hardware

• Possible conflict of interest, if the company who stores your applications decides to create a similar application to what you created on their servers

• Not suited for all highly competitive industries like biotech where intellectual property cannot be protected easily

What is a limitation of three-tier architectures in ERP systems?

• Reduced capital and operating expenditures for IT equipment and support personnel

• Promotes green computing environment as servers in cloud run on clean energy

• A key limitation with three-tier architectures is that the development environment is reportedly more difficult to use than the visually oriented development of two-tier applications

• No need to install anything on the user’s computer
