- B. To store and manage files
- C. To deploy and manage virtual machines
- D. To execute code in response to events or HTTP requests
正解：D
解説：
Oracle Cloud Infrastructure Functions is a serverless computing service that allows developers to run code without managing servers. It is designed to respond to events or HTTP requests and is ideal for event-driven applications.
質問 # 16
What is the primary purpose of fault domains in Oracle Cloud Infrastructure?
- A. To distribute instances across different physical hardware within an availability domain
- B. To ensure all instances are on the same physical hardware
- C. To connect availability domains with low latency
- D. To handle encryption of traffic between instances
正解：A
解説：
Fault domains in Oracle Cloud Infrastructure are used to distribute instances across different physical hardware within an availability domain. This helps in ensuring high availability and fault tolerance by reducing the impact of hardware failures on instances.
質問 # 17
Why might you choose to use containers instead of virtual machines?
- A. Containers are less flexible in terms of resource allocation.
- B. Containers require more resources to run.
- C. Containers allow for faster startup time and more efficient resource usage.
- D. Containers provide better isolation than virtual machines.
正解：C
解説：
Containers share the host operating system's kernel, leading to quicker startup times and lower overhead compared to virtual machines. They offer more agility and resource efficiency, making them suitable for scalable applications.
質問 # 18
In Oracle Cloud Infrastructure, what does the Universal Credits pricing model allow customers to do?
- A. Use prepaid credits for any eligible cloud service
- B. Receive a fixed amount of resources for a specific price
- C. Pay a fixed price for all services
- D. Pay only for services they use with no upfront commitment
正解：A
解説：
Using prepaid credits for any eligible cloud service is a feature of the Universal Credits pricing model in Oracle Cloud Infrastructure. Customers can allocate their prepaid credits to various services based on their needs and usage.
