Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which of the following four (4) descriptions of containers are accurate?

1. Can be accessed over the internet by IP address or domain name

2. Can scale out as needed

3. Represents a single app and its dependencies

4. Requires you to configure the host virtual machine

The correct answer is: Can be accessed over the internet by IP address or domain name

The choice indicating that containers can be accessed over the internet by IP address or domain name is accurate. Containers are deployed on hosts that are typically configured to have network settings, allowing them to be accessed remotely, often through an IP address or a domain name. This accessibility is a key feature of containers, as they are designed to support distributed applications and microservices architectures, making it easy for developers to expose their applications to users and other services. In the context of other characteristics regarding containers, it's important to note that they can indeed scale out as needed, which is a core advantage of containerization in cloud environments. Containers allow for efficient resource utilization and can quickly be replicated to accommodate increased demand. Additionally, containers represent a single application along with its dependencies, ensuring that the application runs consistently across different environments. This encapsulation helps eliminate compatibility issues between different machines or environments. Lastly, while configuring the host virtual machine is part of deploying a container, it is not a requirement from the container's perspective. Containers are designed to abstract away much of the underlying infrastructure, meaning users typically don't need to manage or configure the host VMs in a traditional sense when working with container orchestration platforms like Kubernetes or Azure Kubernetes Service. Thus, focusing on the other three aspects
