VMware 2V0-71.23 Exam With Confidence Using Practice Dumps

VMware Aria Operations for Applications (formerly VMware Tanzu Observability) is a SaaS solution that collects and analyzes traces, metrics, and logs from various sources, including Tanzu Kubernetes Grid clusters, applications, and services. It provides a single source of truth for actionable insights into the performance, availability, and behavior of the entire application stack. It also enables users to create dashboards, alerts, and reports based on the collected data.

The other options are incorrect because:

• Watches defined infrastructure systems to keep track of health of resources is a description of VMware Tanzu Mission Control, which is another SaaS solution that provides centralized management and governance for Tanzu Kubernetes Grid clusters across multiple platforms.
• Automates the remediation of Kubernetes platform resources based on collected data is a description of VMware Tanzu Service Mesh, which is a service thatcreates an enterprise-class service mesh for consistent control and security for microservices, end users, and data.
• Tracks metrics, logs, and alerts based on specified thresholds is a partial description of VMware Aria Operations for Applications, but it does not mention the trace analysis and the single source of truth features.

A VM class in VMware vSphere with Tanzu specifies the CPU, memory, and resource reservations for a VM10. vSphere with Tanzu offers several preconfigured VM classes which you can use as is, edit, or delete. You can also create custom VM classes in your vCenter Server instance and it will be available to all Supervisor Clusters and the namespaces created in these clusters11.

When you create or edit a VM class, you can configure the following attributes:

• Name: A unique DNS compliant name that identifies the VM class.
• vCPU Count: The number of virtual CPUs (vCPUs) for a VM. This is a VM hardware configuration.
• CPU Resource Reservation: The guaranteed minimum CPU resource allocation for a VM. This value is expressed in percentage (%).
• Memory: The memory configured for a VM in MB, GB, or TB. This is a VM hardware configuration.
• Memory Resource Reservation: The guaranteed minimum memory resource allocation for a VM. This value is expressed in percentage (%).
• Storage: The storage configured for a VM in MB, GB, or TB. This is a VM hardware configuration.

The other options are incorrect because:

• Network is not an attribute that can be configured in a VM class. Network configuration is done at the namespace level by using network policies12.
• Operating system is not an attribute that can be configured in a VM class. Operating system configuration is done at the image level by using content libraries.
• PCI devices are not an attribute that can be configured in a VM class. PCI devices are not supported by vSphere with Tanzu.

Antrea is the default CNI for new Tanzu Kubernetes Grid workload clusters8. Antrea is an open-source Kubernetes networking solution that implements the Container Network Interface (CNI) specification and uses Open vSwitch (OVS) as the data plane9. Antrea supports various features such as network policies, service load balancing, NodePortLocal, IPsec encryption, IPv6 dual-stack, and more10.

The other options are incorrect because:

• Multus CNI is an open-source container network interface plugin for Kubernetes that enables attaching multiple network interfaces to pods11. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.
• Flannel is an open-source simple and easy-to-use overlay network that satisfies the Kubernetes requirements12. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.
• Calico is an open-source network and network security solution for containers, virtual machines, and native host-based workloads13. It is not the default CNI for Tanzu Kubernetes Grid workload clusters.
