You plan to deploy an Azure Container Instance named container1 and need the ability to reuse DNS name labels. Which networking option should container1 use?

The public networking type allows you to specify a DNS name label for your container instance, which can be reused after the container instance is deleted. This is because the DNS name label is associated with the public IP address, which can be released and reallocated. The private networking type places the container instance within a virtual network, and while it can have a private DNS name, it doesn't support the reuse of public DNS name labels in the same way. Deploying to a new subnet on VNet1 is a private networking scenario and doesn't directly address the reuse of public DNS name labels. A confidential SKU refers to a specific security offering for confidential computing and is unrelated to DNS name label reuse.
