An administrator was requested to create a pod with two interfaces to separate the application...

Multus is an open-source container network interface plugin for Kubernetes that enables attaching multiple network interfaces to pods. Contour is an open-source Kubernetes ingress controller that provides dynamic configuration updates and makes use of the Envoy proxy as a data plane. By installing these two packages in a VMware Tanzu Kubernetes Grid cluster, an administrator can create a pod with two interfaces and use Contour to route the application and management traffic to different networks.

The other options are incorrect because:

external-dns is a package that synchronizes exposed Kubernetes services and ingresses with DNS providers. It does not provide multiple interfaces for pods.

cert-manager is a package that automates the management and issuance of TLS certificates from various sources. It does not provide multiple interfaces for pods.

qrafana is not a valid package name. The correct spelling is Grafana, which is a package that provides visualization and analytics for metrics collected by Prometheus. It does not provide multiple interfaces for pods.
