Show Suggested Answer

Suggested Answer: D

To dynamically make Kubernetes resources discoverable to public DNS servers, you can use ExternalDNS. ExternalDNS is a Kubernetes add-on that automates the management of DNS records for your Kubernetes services and ingresses. It can be configured to monitor the changes in your Kubernetes resources and automatically update DNS records in a supported DNS provider. By integrating ExternalDNS with your Kubernetes cluster, you can ensure that the DNS records for your services and ingresses are automatically created, updated, or deleted based on changes in your Kubernetes resources. This allows your Kubernetes resources to be discoverable by external systems through public DNS servers.

D) ExternalDNS all the way. Anything else and you might as well just have your services running in a black box.

ExternalDNS, obviously. Unless you want your Kubernetes resources to be as hard to find as a needle in a haystack.

I'm with Kelvin. D) ExternalDNS is the clear winner here. Unless you want your Kubernetes services to be, you know, undiscoverable.

Gotta be D) ExternalDNS. It's the only option that mentions 'public DNS servers' in the question.

Hmm, I'm torn between B) DynDNS and D) ExternalDNS. Guess I'll go with the one that's Kubernetes-specific.

CoreDNS is a flexible and extensible DNS server that can be easily integrated with Kubernetes. It allows for dynamic updates to DNS records, making it a suitable choice for making resources discoverable to public DNS servers.

I'm pretty sure it's C) CoreDNS. That's the default DNS server in Kubernetes, right?
