  Explanation/Reference:

  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 47:

  What is the Kubernetes component that is responsible for workload creation?

  A. API Sep/er
  B. Scheduler
  C. etcd
  D. Kubelel
  B. Scheduler

  ---

  Explanation/Reference:

  The Scheduler is the Kubernetes component that is responsible for workload creation. The Scheduler is responsible for assigning pods to nodes based on various factors, such as resource availability, node affinity, taints and tolerations, and pod priority. The Scheduler watches for newly created pods that have no node assigned, and selects a suitable node for them to run on. The Scheduler then informs the API server of its decision, and the API server binds the pod to the node. References: Scheduling | Kubernetes, Kubernetes Components | Kubernetes

• Question 48:

  What is the purpose of a service mesh?

  A. Provides dynamic application load balancing and autoscaling across multiple clusters and multiple sites.
  B. Provides a centralized, global routing table to simplify and optimize traffic management.
  C. Provides service discovery across multiple clusters.
  D. Provides an infrastructure layer that makes communication between applications possible, structured, and observable.
  D. Provides an infrastructure layer that makes communication between applications possible, structured, and observable.

  ---

  Explanation/Reference:

  A service mesh is a dedicated infrastructure layer that you can add to your applications to provide capabilities like observability, traffic management, and security, without adding them to your own code. A service mesh consists of network proxies paired with each service in an application and a set of management processes. The proxies are called the data plane and the management processes are called the control plane. The data plane intercepts calls between different services and processes them; the control plane is the brain of the mesh that configures and monitors the data plane1. A service mesh makes communication between applications possible, structured, and observable by providing features such as load balancing, service discovery, encryption, authentication, authorization, routing, retries, timeouts, fault injection, metrics, logs, and traces2. The other options are incorrect because: Provides dynamic application load balancing and autoscaling across multiple clusters and multiple sites is a description of VMware Tanzu Service Mesh Global Namespaces feature3, which is built on top of a service mesh. It is not the purpose of a service mesh in general. Provides a centralized, global routing table to simplify and optimize traffic management is a description of VMware Tanzu Service Mesh Global Mesh Network feature4, which is also built on top of a service mesh. It is not the purpose of a service mesh in general. Provides service discovery across multiple clusters is a partial description of a service mesh, but it does not capture the full scope of its purpose. Service discovery is one of the features that a service mesh provides, but it is not the only one. References: What's a service mesh?, The Istio service mesh, Service mesh - Wikipedia
