NEW QUESTION # 114
Which kubectl command syntax is valid for implementing a rolling update deployment strategy in Kubernetes? (Choose the best answer.)
Answer: A
Explanation:
The correct syntax for implementing a rolling update deployment strategy in Kubernetes using the kubectl command is: kubectl rolling-update < deployment-name > --image=image:v2 This command initiates a rolling update of the specified deployment by updating the container image to image:v2. The rolling update strategy ensures that the new version of the application is gradually deployed while maintaining availability and minimizing downtime.
NEW QUESTION # 115
Which OCI CLI command generates or merges the cluster configuration file required to authorize kubectl access to an OKE cluster?
Answer: D
Explanation:
Oracle documents oci ce cluster create-kubeconfig as the OCI CLI operation used to create the Kubernetes configuration file required for access to an OKE cluster. The command accepts the cluster OCID through -- cluster-id and, by default, writes or updates $HOME/.kube/config. The resulting kubeconfig contains the cluster endpoint and the OCI CLI authentication mechanism that enables kubectl to obtain authentication tokens when communicating with the Kubernetes API server. Commands named update-kubeconfig, download-kubeconfig, and generate-kubeconfig are not valid OCI CLI subcommands for this operation.
Therefore, oci ce cluster create-kubeconfig is the documented command for establishing the local kubeconfig required to administer an OKE cluster through kubectl.
NEW QUESTION # 116
Which of the following step is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl?
Answer: A
Explanation:
The step that is NOT required for setting up the Container Engine for Kubernetes (OKE) cluster access using a local installation of kubectl is to generate an Auth token from the OCI console. The authentication for accessing the OKE cluster using kubectl can be performed using the OCI CLI configuration, specifically the API signing key pair and the kubeconfig file. Here are the correct steps for setting up the OKE cluster access using a local installation of kubectl: Set up the kubeconfig file: The kubeconfig file contains the necessary information to authenticate and access the OKE cluster using kubectl. It includes details such as the cluster endpoint, authentication method, and credentials. Generate an API signing key pair (if you do not already have one) and upload the public key of the API signing key pair: The API signing key pair is used for authentication with the OCI services. The public key of the key pair needs to be uploaded to the OCI Console to associate it with your user account. Install and configure the Oracle Cloud Infrastructure (OCI) CLI: The OCI CLI provides a command-line interface to interact with the OCI services. It needs to be installed and configured with your OCI credentials, including the user ' s OCID, tenancy OCID, region, and the path to the API signing key pair. By completing these steps, you can configure kubectl to access and manage your OKE clusters from your local machine using the OCI CLI authentication configuration.
NEW QUESTION # 117
Which limit represents the maximum write throughput supported per partition of an Oracle Cloud Infrastructure stream when designing high-volume data producer workloads?
Answer: B
Explanation:
Oracle ' s current OCI Streaming limits specify that each stream partition supports a total data write rate of 1 MB per second. Partition count is therefore a fundamental capacity-planning parameter for producer workloads. If an application is expected to produce more than 1 MB per second, the stream must contain enough partitions to distribute the required ingress throughput appropriately. Oracle ' s partitioning guidance likewise states that expected throughput should be calculated before stream creation because each partition is limited to the 1 MB-per-second write rate. The 2 MB figure is not the documented write limit, while 4 MB and 8 MB exceed the per-partition ingress capacity. Therefore, the maximum write throughput represented by the available choices is 1 MB per second.
NEW QUESTION # 118
Which TWO are part of the Cloud Native Computing Foundation (CNCF) container runtime? (Choose two.)
Answer: C,D
Explanation:
The two components that are part of the Cloud Native Computing Foundation (CNCF) container runtime are:
containerd: containerd is an open-source container runtime that provides a runtime environment for containers, including managing container images, executing containers, and handling container lifecycle events. It is designed to be lightweight and extensible, providing the necessary functionality to run containers efficiently. runc: runc is a lightweight container runtime that serves as a reference implementation of the Open Container Initiative (OCI) runtime specification. It is responsible for launching and managing containers based on OCI specifications, including handling container isolation, namespaces, cgroups, and other low-level container operations. These two components, containerd and runc, are widely used in the container ecosystem and are part of the CNCF ' s efforts to promote and develop open-source technologies for cloud-native computing.
