You plan to deploy a containerized application that requires .NET Core. You need to create a container image for the application. The image must be as small as possible. Which base image should you use?
Nano Server base container image
This is our smallest base container image. As mentioned above, this means less APIs available. For Nano Server, we focused on scenarios where developers will be writing new applications on which the framework can target the specific APIs of Nano Server. Examples of frameworks, languages, or apps that are supported on Nano Server are .Net Core (now called .Net)
Here’s a brief overview of the different container images and their best use cases:
1. Nano Server:
o Best for lightweight, modern applications built on .NET Core or similar frameworks.
o Ideal for scenarios requiring minimal APIs and fast scaling.
2. Server Core:
o Suitable for "lift-and-shift" scenarios where existing Windows Server applications are moved to containers without code changes.
o Provides medium-sized API support.
3. Windows:
o Offers full Windows API support, making it ideal for applications requiring extensive Windows libraries.
o Largest image, suitable for workloads needing comprehensive compatibility.
4. Windows Server:
o Similar to the Windows image but slightly smaller.
o Supports server-specific features and applications.
Answer: B, Nano Server
Nano Server is the smallest Windows container base image available and is specifically optimized for running .NET Core applications in containers.

Nano Server is a lightweight, minimal-footprint version of Windows Server designed specifically for containerized applications.
It has a smaller image size compared to Server Core and is well-suited for running .NET Core applications in containers, helping to reduce the overall image size and resource usage.
