Important IBM C1000-150 Exam Questions

Answer: D

Explanation:

A best practice for application pod high availability is to use multiple pods across both worker and master nodes. This ensures redundancy and increased availability of the application. Additionally, using multiple small pods on a master node can improve resource utilization and reduce overall costs. For more information on best practices for application pod high availability, please refer to the following references: 1. 'Pod Autoscaler Best Practices' from Kubernetes Docs: https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale-best-practices/ 2. 'High Availability for Containerized Workloads with Kubernetes' from AWS: https://aws.amazon.com/blogs/compute/high-availability-for-containerized-workloads-with-kubernetes/.

Answer: C

Explanation:

A Cloud Pak for Business Automation starter deployment can be upgraded to a production deployment if required. It is designed to provide a quick and easy way to get started with the capabilities offered by the Cloud Pak for Business Automation. It is possible to include the Automation Document Processing capability in a starter deployment. The starter deployment uses the Operator Lifecycle Manager to deploy and manage the components of the Cloud Pak for Business Automation.

Answer: D

Explanation:

To generate a higher level of detail in operator logs, you can configure a detailed operator trace in a ConfigMap. This allows you to specify the level of logging for different components of the operator and can provide more information about the operator's behavior. The level of logging can be set to 'debug', 'info', 'warning' or 'error' in the ConfigMap. You can access the ConfigMap by using the 'oc edit configmap' command and then editing the 'loglevel' field.

It's also important to note that there are other ways to troubleshoot issues with operators and their logs, such as running the 'oc logs' command on the operator pod, or using the 'oc adm must-gather' command to collect cluster state and diagnostic information.

Answer: B

Explanation:

The Business Automation Workflow (BAW) transaction log file contains information about the data that is written to databases. It records the data that is written to the database as part of a BAW process. This can include information such as the process instance ID, the task that was executed, the user that performed the task, and the data that was written to the database. This log file is useful for troubleshooting and auditing purposes.

Answer: D

Explanation:

The command 'oc get pods -n NAMESPACE' is used to verify that all the pods are running after Operators are deployed. This command allows you to view the status of all pods in a specific namespace, which is useful for troubleshooting issues and ensuring that all pods are running correctly. The command will show the name, status, and other information about each pod in the specified namespace.

It's important to note that the other commands such as oc debug pods, oc describe pods, and oc status pods can also be used to troubleshoot issues but oc get pods is the command that is used to verify that all the pods are running after Operators are deployed.
