Which kubectl command updates objects?
- A. kustomize <filename> yaml
- B. create - <filename> yam
- C. apply -f <filename>.yaml
Answer: C
Explanation:
Explanation
Use kubectl apply to create or update resources from a file or stdin. This command does a three-way diff between the previous configuration, the input configuration, and the current configuration of the resource, and then applies the changes.
Use kubectl patch to update Kubernetes API objects in place. Do a strategic merge patch or a JSON merge patch.
Use kubectl replace to delete and re-create the resource. You can use this command to update immutable fields of a resource, such as its kind or name.

Which open-source projects provide data visualization in the kyma-system Namespace? Note: There are 2 correct Answers to this question.
- A. Grafana
- B. Prometheus Web UI
- C. Vector
- D. Loki
Answer: A,B
Explanation:
Explanation
Grafana and Prometheus Web UI are the open-source projects that provide data visualization in the kyma-system Namespace. Grafana is a visualization and analysis tool that can create dashboards from various data sources, such as Prometheus and Loki. Prometheus Web UI is a web interface that allows users to query and visualize the metrics collected by Prometheus. Both Grafana and Prometheus Web UI can be accessed from the Kyma Dashboard by selecting the namespace kyma-system and choosing the menu option Configuration -> Tools.

NEW QUESTION # 29
Where are Kubernetes objects persisted?
- A. The row store
- B. The etod key-value store
- C. The column store
- D. The key value store
Answer: B
Explanation:
Explanation
Kubernetes objects are persisted in the etcd key-value store, which is a distributed and consistent data store that serves as the backbone of the Kubernetes cluster. The etcd store holds the configuration data, state, and metadata of the cluster, and is accessed by the Kubernetes API server. The etcd store ensures that the cluster state is consistent and reliable across multiple nodes and failures. The other options are not relevant for Kubernetes object persistence, as they are either different types of data stores (column store, row store) or misspelled (key value store).

NEW QUESTION # 30
How can you create a Kubernetes object from a file?
- A. kubectl install-from-file <file>
- B. kubectl install t <file>
- C. kubectl create -from-file <file>
- D. kubectl create -f <file>
Answer: D
Explanation:
Explanation
You can use the kubectl create -f command to create a Kubernetes object from a file. The file can be a YAML or JSON file that specifies the configuration of the object, such as its apiVersion, kind, metadata, and spec.
The file can also be a URL that points to a remote file. The kubectl create -f command will send a POST request to the Kubernetes API server with the content of the file, and the API server will create the object according to the file. The other options are not valid kubectl commands. References: Imperative Management of Kubernetes Objects Using Configuration Files, Kubernetes Object Management

NEW QUESTION # 33
What are some features of Kubernetes? Note: There are 3 correct Answers to this question.
- A. Process management and optimization
- B. Integration and assessment
- C. Extensibility and ecosystem
- D. Automated rollouts and rollbacks
- E. Immutability and self-healing
Answer: C,D,E
Explanation:
Explanation
Some of the features of Kubernetes are:
Immutability and self-healing: Kubernetes treats pods as immutable, meaning that they are not modified after they are created. Instead, pods are replaced with new ones when they need to be updated or repaired. This ensures that the pods are always in a consistent and predictable state. Kubernetes also monitors the health and availability of the pods and automatically restarts, reschedules, or replicates them if they fail or become unresponsive1.
Extensibility and ecosystem: Kubernetes is designed to be extensible and modular, allowing users to customize and extend its functionality according to their needs. Kubernetes supports various extensions, such as custom resources, operators, admission controllers, schedulers, network plugins, storage plugins, and more. Kubernetes also has a large and vibrant ecosystem of tools, services, and applications that are built on top of or integrate with it2.
Automated rollouts and rollbacks: Kubernetes enables users to deploy and update their applications with zero downtime, using declarative configuration and rolling updates. Kubernetes ensures that only a certain number of pods are changed at a time, and that the new pods are ready before terminating the old ones. Kubernetes also tracks the history of each update and allows users to roll back to a previous version if something goes wrong3.

NEW QUESTION # 34
Which service does the SAP BTP service operator on SAP BTP, Kyma runtime use to consume services on SAP BTP?
- A. SAP API Business Hub
- B. SAP Service Manager
- C. SAP Service Marketplace
Answer: B
Explanation:
Explanation
The SAP BTP service operator on SAP BTP, Kyma runtime uses the SAP Service Manager to consume services on SAP BTP. The SAP Service Manager is a component that provides a unified way of provisioning, accessing, and managing services from different providers and platforms. The SAP Service Manager implements the Open Service Broker API (OSB API) to communicate with service brokers and expose their services to applications. The SAP BTP service operator on SAP BTP, Kyma runtime leverages the SAP Service Manager to create and manage service instances and bindings for SAP BTP services in the Kyma cluster. The SAP BTP service operator also synchronizes the service catalog from the SAP Service Manager to the Kyma Service Catalog, so that users can discover and consume SAP BTP services through the Kyma Console or the Kubernetes API.

NEW QUESTION # 39
If an application requires a persistent state between reboots, what must be done before it can be deployed?
- A. Create a Persistent Volume Claim for a pod.
- B. Create a Persistent Volume in the namespace
- C. Create a new entry in etcd.
Answer: A
Explanation:
Explanation
A Persistent Volume Claim (PVC) is a request for storage by a user. It is similar to a Pod, which is a request for compute resources by a user. A PVC enables a Pod to consume a slice of the available storage in the cluster without knowing the details of the underlying storage infrastructure. A PVC is associated with a StorageClass, which defines the type and characteristics of the storage. A PVC is also bound to a Persistent Volume (PV), which is an abstraction of the physical or cloud-based storage resource. A PV is created by the cluster administrator and has a lifecycle independent of any Pod. A PVC can specify the size, access mode, and storage class of the PV it requires. Before deploying an application that needs persistent state, a user must create a PVC for the Pod that will run the application. The PVC will then be automatically bound to a suitable PV by the cluster, or dynamically provisioned if the storage class supports it. The Pod can then mount the PVC as a volumeand access the persistent storage12345.
