VMware 2V0-71.23 Online Questions & Answers

• Question 61:

  What is the function of Velero?

  A. Backup and restore Kubernetes clusters
  B. Monitor cluster services
  C. Publish DNS records for applications to DNS servers
  D. Collect data and logs from different sources, unify them, and send them to multiple destinations
  A. Backup and restore Kubernetes clusters

  ---

  Explanation/Reference:

  Velero is an open source tool that can safely backup and restore, perform disaster recovery, and migrate Kubernetes cluster resources and persistent volumes. Velero can capture both the Kubernetes objects and the persistent volumes associated with an application, and restore them in a different cluster or namespace. Velero also supports different storage providers to store its backups, such as AWS S3, Azure Blob Storage, Google Cloud Storage, and more. References:

• Question 62:

  Which two package management tools can be used to configure and install applications on Kubernetes? (Choose two.)

  A. Grafana
  B. Fluent bit
  C. Carvel
  D. Helm
  E. Multus
  C. Carvel
  D. Helm

  ---

  Explanation/Reference:

  Two package management tools that can be used to configure and install applications on Kubernetes are: Carvel. Carvel is a set of tools that provides a simple, composable, and flexible way to manage Kubernetes configuration, packaging, and deployment. Carvel includes tools such as kapp, which applies and tracks Kubernetes resources in a cluster; ytt, which allows templating YAML files; kbld, which builds and pushes images to registries; kpack, which automates image builds from source code; and vendir, which syncs files from different sources into a single directory. Carvel is integrated with VMware Tanzu Kubernetes Grid and can be used to deploy and manage applications on Tanzu clusters. Helm. Helm is a tool that helps users define, install, and upgrade complex Kubernetes applications using charts. Charts are packages of pre-configured Kubernetes resources that can be customized with values. Helm uses a client- server architecture with a command line tool called helm and an in-cluster component called Tiller. Helm can be used to deploy applications from the official Helm charts repository or from custom charts created by users or vendors. Helm is also integrated with VMware Tanzu Kubernetes Grid and can be used to deploy and manage applications on Tanzu clusters.

• Question 63:

  What project does Contour leverage for the data plane?

  A. NSX Load Balancer
  B. Istio
  C. Envoy
  D. Prometheus
  C. Envoy

  ---

  Explanation/Reference:

  Contour is an open-source Kubernetes ingress controller that provides dynamic configuration updates and makes use of the Envoy proxy as a data plane1. Envoy is an open-source edge and service proxy that can handle large volumes of

  network traffic between services in a cloud-native environment2. Contour leverages Envoy's advanced features such as load balancing, health checking, dynamic service discovery, circuit breaking, rate limiting, and more3. Contour also

  integrates with Envoy's external authorization filter to support external authentication and authorization providers4.

  The other options are incorrect because:

  NSX Load Balancer is a VMware solution that provides L4 and L7 load balancing and ingress control for Kubernetes clusters5. It is not the data plane for Contour. Istio is an open-source service mesh that provides a uniform way to connect,

  secure, control, and observe services in a distributed system6. It is not the data plane for Contour.

  Prometheus is an open-source systems monitoring and alerting toolkit that can collect metrics from various sources, including Kubernetes clusters7. It is not the data plane for Contour.
