Question 1

When using the product Certificate manager service, what might one consider in regards to the default setting of refreshing certificates?

APods that use the refreshed certificate are automatically restarted.

BCertificates cannot be configured to automatically refresh.

CCertificate Refresh is disabled by default.

DPods that use the refreshed certificate need to be manually restarted.

Answer : C

When using the product Certificate manager service, the default setting of refreshing certificates is disabled. Pods that use the refreshed certificate do not need to be manually restarted, as certificate refresh will be automatically enabled when the certificate expires.

Question 2

How can diagnostic commands be run in order to avoid packaging extraneous log files?

ARun them from an existing directory.

BRun them from an empty directory.

CEnable the debug parameter before running them.

DRun them with the --replace parameter.

Answer : B

In order to avoid packaging extraneous log files, diagnostic commands should be run from an empty directory. This will ensure that only the necessary log files are packaged.

Question 3

After scaling a Process Mining deployment, which two replica set values are updated?

AREADY

BPROGRESS

CWAITING

DCOMPLETED

EDESIRED

Answer : D, E

After scaling a Process Mining deployment, the replica set values for COMPLETED and DESIRED are updated.

Question 4

Which command is used to verify that all the pods are running after Operators are deployed?

Aoc debug pods -n NAMESPACE

Boc describe pods -n namespace

Coc status pods -n NAMESPACE

Doc get pods -n NAMESPACE

Answer : D

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.

Question 5

What can be done to generate a higher level of detail if the operator logs are not detailed enough?

ARun the logs command on the operator pod.

BSpecify the image when you run the oc adm must-gather command.

CIncrease in the verbosity in the Ansible log.

DConfigure a detailed operator trace in a ConfigMap.

Answer : D

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.

Question 7

The migration of data from Cloud Pak for Business Automation versions that do not support an upgrade require an Administrator to follow which process?

AAll Cloud Pak for Business Automation versions currently support a direct upgrade with the standard applicable procedures.

BUninstall the current deployment and follow the migration instructions for each component to point to the existing persistent stores.

CUpgrade the core capabilities first, then the Cloud Pak for Business Automation Operator, followed by the Foundation Operator.

DMirror the existing persistent stores allowing the Operator to upgrade accordingly.

Answer : B

Migrating data from a Cloud Pak for Business Automation version that does not support an upgrade requires an Administrator to uninstall the current deployment and follow the migration instructions for each component, pointing them to the existing persistent stores

When migrating data from Cloud Pak for Business Automation versions that do not support an upgrade, an Administrator must uninstall the current deployment and follow the migration instructions for each component to point to the existing persistent stores. This process involves migrating data from the existing databases and persistent volumes to the new deployment. This process may also require creating new configurations and customizing the new deployment to match the previous one.
