A Deployment is a Kubernetes object that allows you to perform a rolling update without disrupting services. A Deployment manages a ReplicaSet or a Pod and provides declarative updates for them. You can describe the desired state of your application using a Deployment, and it will change the actual state to the desired state at acontrolled rate. A Deployment also allows you to roll back to a previous version if something goes wrong during the update14.

The other options are incorrect because:

• A ReplicaSet is a Kubernetes object that ensures that a specified number of pod replicas are running at any given time. It does not provide any mechanism for updating or rolling back pods15.
• A Service is a Kubernetes object that defines a logical set of pods and a policy to access them. It does not provide any mechanism for updating or rolling back pods16.
• A Container is not a Kubernetes object, but rather a component of a Pod. A Pod is the smallest deployable unit of computing in Kubernetes. A Pod can contain one or more containers that share storage and network resources. A Pod does not provide any mechanism for updating or rolling back itself or its containers17.

VMware Tanzu Service Mesh Advanced is the VMware product UI that allows browsing Global Namespace Topology. A Global Namespace is a logical group of services that span multiple clusters and clouds, providing consistent service discovery, security, and observability10. A Global Namespace Topology is a graphical representation of the services and their connections in a Global Namespace, showing the key metrics and health status of each service11. To browse the Global Namespace Topology, an administrator can use the Tanzu Service Mesh Console, which is the web-based user interface for managing Tanzu Service Mesh12.

The other options are incorrect because:

• NSX Advanced Load Balancer is a VMware product that provides load balancing, web application firewall, and container ingress services for applications across various data centers and clouds13. It does not allow browsing Global Namespace Topology.
• NSX is a VMware product that provides network virtualization and security for applications across various data centers and clouds. It does not allow browsing Global Namespace Topology.
• Tanzu Mission Control is a VMware product that provides centralized management and governance for Kubernetes clusters across multiple teams and clouds. It does not allow browsing Global Namespace Topology.

VMware Tanzu Mission Control and Tanzu CLI package plugin are two methods that can be used to install Fluent Bit on a VMware Tanzu Kubernetes Grid cluster. VMware Tanzu Mission Control is a centralized management platform for Kubernetes clusters across different environments. It allows users to install Fluent Bit on any attached cluster from the web console or the CLI, and configure the output plugins for log forwarding. Tanzu CLI package plugin is a command-line tool that enables users to interact with VMware Tanzu packages and services. It allows users to install Fluent Bit from a package repository on any standalone management or workload cluster, and configure the output plugins for log forwarding.
