  Which statement describes a Global Namespace in VMware Tanzu Service Mesh?

  A. Apply a single policy to multiple namespaces across multiple clusters.

  B. Automatic placement of the workload to any global cluster based on traffic demand.

  C. Define an application boundary and provides consistent traffic routing, connectivity, resiliency, and security for applications across multiple clusters.

  D. Provide distributed ingress and egress services to support multiple namespaces across multiple clusters.

  Correct Answer: C

  The statement that correctly describes a global namespace in VMware Tanzu Service Mesh is that it defines an application boundary and provides consistent traffic routing, connectivity, resiliency, and security for applications across multiple clusters. A global namespace is a logical abstraction of an application from the underlying infrastructure that spans across multiple clusters and clouds4. A global namespace connects the resources and workloads that make up the application into one virtual unit and manages their identity, discovery, connectivity, security, and observability4. A global namespace also enables automatic service discovery and cross-cluster communication within the application boundary4. References: Global Namespaces - VMware Docs

• Question 23:

  Which statement describes a Container Storage Interface (CSI) in VMware Tanzu Kubernetes Grid?

  A. It is a plug-in that onlyworks with vSphere object storage.

  B. It is a plug-in that is only used for clusters which require cloud native storage.

  C. It is a plug-in that allows providers to expose storage as persistent storage.

  D. It is a plug-in that is required for ephemeral storage.

  Correct Answer: C

  A Container Storage Interface (CSI) in VMware Tanzu Kubernetes Grid is a plug-in that allows providers to expose storage as persistent storage for Kubernetes clusters. CSI is a standard interface that defines an abstraction layer for container orchestrators to work with storageproviders3. VMware Tanzu Kubernetes Grid supports StorageClass objects for different storage types, provisioned by Kubernetes internal ("in- tree") or external ("out-of-tree") plug-ins. Two of the supported storage types are vSphere Cloud Native Storage (CNS) and Amazon EBS, which use the vSphere CSI driver and the AWS EBS CSI driver respectively4.

• Question 25:

  Which three capabilities are supported by VMware Aria Operations for Applications (formerly VMware Tanzu Observability)? (Choose three.)

  A. Unified log management

  B. Setting Service Objectives

  C. Integration with VMware Aria Automation Config (formerly vRealize Automation SaltStack Config)

  D. Create a Tanzu Kubernetes cluster

  E. Event tracing

  F. Out-of-the-box and user-configurable dashboards

  Correct Answer: AEF

  Three capabilities that are supported by VMware Aria Operations for Applications (formerly VMware Tanzu Observability) are: Unified log management: Users can browse logs to troubleshoot their issues, for example, if they notice anomalies on their metrics charts or see that a service on the application map has large latency value. Users can also drill into related logs directly from charts, alerts, and traces2. Event tracing: Users can work with a service map, examine traces and spans, and drill down into problem areas in their code. Users can also view traces and spans from a single source of truth across logs, metrics, and traces1. Out-of-thebox and user-configurable dashboards: Users can visualize their data based on query results in various chart types (such as line plot, point plot, table, pie chart, etc.) and organize them in dashboards. Users can also interact with charts and dashboards in real time, such as zoom in, zoom out, change the time window, change the focus, and so on1.

• Question 28:

  What is the role of Prometheus in a VMware Tanzu Kubernetes Grid cluster?

  A. Provide the functionality of a lightweight log processor and forwarder that allows you to collect data and logs from different sources.

  B. Collect metrics from target clusters at specified intervals, evaluate rule expressions, display the results, and trigger alerts if certain conditions arise.

  C. Inject time-series database (TSDB) data into high-quality graphs and visualizations.

  D. Extend the open-source Docker distribution by adding the functionalities usually required by users such as security and identity control and management.

  Correct Answer: B

  Prometheus is an open-source systems monitoring and alerting toolkit that can collect metrics from target clusters at specified intervals, evaluate rule expressions, display the results, and trigger alerts if certain conditions arise8. Tanzu

  Kubernetes Grid includes signed binaries for Prometheus that users can deploy on workload clusters to monitor cluster health and services9. Prometheus uses a pull model to scrape metrics from various sources, such as Kubernetes nodes,

  pods, services, and endpoints. Prometheus stores the collected metrics in a time-series database and allows users to query them using PromQL, a powerful query language. Prometheus also supports defining alert rules based on metric

  values and sending notifications to external systems, such as Alertmanager8.

  The other options are incorrect because:

  Provide the functionality of a lightweight log processor and forwarder that allows you to collect data and logs from different sources is a description of Fluent Bit, which is an open-source log processor and forwarder that can be used to collect

  data and logs from Kubernetes clusters and send them to various destinations10. Fluent Bit is not part of Tanzu Kubernetes Grid. Inject time-series database (TSDB) data into high-quality graphs and visualizations is a description of Grafana,

  which is an open-source visualization and analytics software that can be used to query, visualize, alert on, and explore metrics from various sources, including Prometheus11. Grafana is not part of Tanzu Kubernetes Grid.

  Extend the open-source Docker distribution by adding the functionalities usually required by users such as security and identity control and management is a description of Harbor, which is an open-source cloud native registry that can be

  used to store, sign, and scan container images for vulnerabilities12. Harbor is not part of Tanzu Kubernetes Grid.

• Question 29:

  Which version of VMware vSphere introduces the capability for provisioning a workload cluster using a cluster class (ClusterClass) from VMware Tanzu Mission Control?

  A. VMware vSphere 8

  B. VMware vCenter Server 6.7 Update 3

  C. VMware vSphere 6.7

  D. VMware

  Correct Answer: A

  VMware vSphere 8 is the version of VMware vSphere that introduces the capability for provisioning a workload cluster using a cluster class (ClusterClass) from VMware Tanzu Mission Control. ClusterClass is a feature of Cluster API that allows users to define a reusable cluster configuration template and use it to create consistent clusters with a predefined shape and size. Tanzu Mission Control leverages ClusterClass to enable users to create Tanzu Kubernetes clusters in vSphere with Tanzu using a default cluster class. The default cluster class specifies the number of control plane nodes, worker nodes, and the resources allocated to each node. To use ClusterClass with Tanzu Mission Control, the vSphere environment must be running version 8.0 or later, and the Supervisor Cluster must be upgraded from vSphere 7.0U3. The other options are incorrect because: VMware vCenter Server 6.7 Update 3 is not a version of VMware vSphere, but rather a version of VMware vCenter Server, which is the centralized management platform for vSphere environments. VMware vCenter Server 6.7 Update 3 does not support ClusterClass or Tanzu Mission Control. VMware vSphere 6.7 is an older version of VMware vSphere that does not support ClusterClass or Tanzu Mission Control. VMware vSphere 6.7 reached end of general support on October 15, 2022. VMware is not a version of VMware vSphere, but rather the name of the company that develops and sells VMware vSphere and other products.
