Your company is designing a multi-tenant application that will use elastic pools and Azure SQL databases. The application will be used by 30 customers.
You need to design a storage solution for the application. The solution must meet the following requirements:
✑ Operational costs must be minimized.
✑ All customers must have their own database.
✑ The customer databases will be in one of the following three Azure regions: East US, North Europe, or South Africa North.
What is the minimum number of elastic pools and Azure SQL Database servers required?
Answer:
The minimum number of elastic pools and Azure SQL Database servers required is:
three elastic pools and one Azure SQL Database server.
Explanation:
The above will ensure that the Azure regions of East US, North Europe, or South Africa North are grouped into their three elastic pools. Since cost minimization must be achieved, at the same time, one Azure SQL Database server will be enough to manage the 30 databases required, with one for each customer. Creating more than one Database server will increase the operational costs.

Give two example computer applications for which connection-oriented service is appropriate. Now give two examples for which connectionless service is best.
Answer:
File transfer, remote login, and video on demand need connection-oriented service.
Explanation:
I HOPE THIS HELPS
A connection-oriented service is a data transfer mechanism used at the session layer. Connectionless service is an in-data communication that is used to convey data at the OSI model's transport layer.
What is a connection-oriented service?A connection-oriented service is a data transfer mechanism used at the session layer. Unlike its opposite, connectionless service, connection-oriented service necessitates the establishment of a session connection between the sender and recipient, similar to a phone conversation. Although not all connection-oriented protocols are considered reliable, this method is generally thought to be more reliable than a connectionless service.
What is a connection-less service?Connectionless service is a notion in data communications that is used to convey data at the OSI model's transport layer (layer 4). It refers to data transmission between two nodes or terminals in which data is transferred from one node to the other without first confirming that the destination is accessible and ready to accept the data. There is no need for a session connection between the sender and the receiver; the sender just begins delivering data.
Telnet, rlogin, and FTP are examples of services that leverage connection-oriented transport services. And Connectionless services include User Datagram Protocol (UDP), Internet Protocol (IP), and Internet Control Message Protocol (ICMP).
