Final answer:
The correct statements about SaaS are that users can often pay monthly with possible additional fees, and they connect to these services over the Internet using a web browser; hence, two statements given are true.
Step-by-step explanation:
For Software as a Service (SaaS), which of the following are true:
- The statement that SaaS does not typically have pay-as-you-go pricing, unlike PaaS and IaaS, is false. SaaS often offers pay-as-you-go pricing models.
- It is true that you often pay monthly for your SaaS applications like Shopify, and there might be an additional per transaction fee.
- Another true statement is that users connect to SaaS over the Internet, usually with a web browser.
- The claim that all of the underlying infrastructure is run and managed by your own staff at your Data Center is false in the context of SaaS as the service provider is responsible for managing the infrastructure.
Therefore, the correct answers are options b and c, meaning that '2 of the above are correct' as stated in option e.
