Oracle Cloud Infrastructure 2025 Developer Professional Sample Questions (Q20-Q25):

NEW QUESTION # 20
Which kubectl command syntax is valid for implementing a rolling update deployment strategy in Kubernetes? (Choose the best answer.)

A. kubectl update -c <container> --iniage=image: v2
B. kubectl rolling-update <deployment-name> --image=image:v2
C. kubectl update <deployment-name> --image=image:v2
D. kubectl upgrade -c <container> --image=image:v2

Answer: B

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 # 21
(CHK_4>2) Which TWO statements are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service? (Choose two.)

A. A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys.
B. The throughput of a stream is defined by a partition. A partition provides 1 MB/sec data input and 2 MB/sec data output.
C. OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days.B
D. Although OCI Streaming automatically encrypts all data while in transit, it is the developer's responsibility to encrypt data at rest, if needed.
E. OCI Streaming can support up to 2,000 requests per second to each partition.

Answer: A,E

Explanation:
The two statements that are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service are: A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys. This statement is not valid because the OCI Streaming service currently supports only private endpoints. Customer managed encryption keys are not currently supported for OCI Streaming. OCI Streaming can support up to 2,000 requests per second to each partition. This statement is not valid because the throughput of a stream is not defined by the partition in terms of requests per second. The throughput of a stream is defined in terms of data input and output rates. Each partition provides 1 MB/sec data input and 2 MB/sec data output, but it does not correspond to a specific number of requests per second. The other statements are valid: OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days. Although OCI Streaming automatically encrypts all data while in transit, it is the developer's responsibility to encrypt data at rest, if needed.

NEW QUESTION # 22
You encounter an unexpected error when invoking Oracle Functions from your Cloud Shell session named myfunction in the myapp application. Which option will get you more information on the error?

A. fn --debug invoke myapp myfunction
B. Contact Oracle support with your error message
C. fn --verbose invoke myapp myfunction
D. DEBUG=1 fn invoke myapp myfunction

Answer: D

Explanation:
The option that will get you more information on the error when invoking Oracle Functions from your Cloud Shell session is: "DEBUG=1 fn invoke myapp myfunction". Setting the environment variable DEBUG=1 before invoking the function using the fn command allows you to enable debug mode, which provides more detailed information about the execution of the function. This can be useful for troubleshooting and understanding the root cause of the error. By using the command "DEBUG=1 fn invoke myapp myfunction", the function invocation will be executed with debug mode enabled, and additional debug information will be displayed in the console output. This information can include stack traces, detailed error messages, and other relevant details that can help identify and resolve the issue. Using the verbose option (--verbose) or debug option (--debug) with the fn command may also provide additional information, but the specific behavior may depend on the version and configuration of the fn CLI tool. While contacting Oracle support with the error message is always an option, enabling debug mode using the DEBUG=1 environment variable provides immediate access to more detailed information and can help in diagnosing and resolving the error more efficiently.

NEW QUESTION # 23
Which two "Action Type" options are NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition? (Choose two.)

A. Functions
B. Slack
C. Streaming
D. Email
E. Notifications

Answer: B,D

Explanation:
The two "Action Type" options that are NOT available in an Oracle Cloud Infrastructure (OCI) Events rule definition are: Email (Correct) Slack (Correct) The available "Action Type" options in OCI Events rule definition include Functions, Notifications, and Streaming. However, email and Slack are not directly supported as action types in OCI Events. Instead, you can use Notifications to send notifications to various notification channels, including email and Slack, through the OCI Notifications service.

NEW QUESTION # 24
Which TWO are required to access the Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster from the kubectl CLI? (Choose two.)

A. OCI Identity and Access Management (IAM) Auth Token.
B. A configured OCI API signing key pair.
C. An SSH key pair with the public key added to the cluster worker nodes.
D. Install and configure the OCI CLI.
E. Tiller enabled on the OKE cluster.

Answer: B,D

Explanation:
The correct options are: A configured OCI API signing key pair: The API signing key pair is used for authentication and authorization to access OCI resources, including the OKE cluster. The private key should be configured on your local machine to authenticate API requests. An SSH key pair with the public key added to the cluster worker nodes: This is required for secure SSH access to the worker nodes in the OKE cluster. You need to generate an SSH key pair and add the public key to the cluster's worker node pool during cluster creation or update. Therefore, the correct options are having a configured OCI API signing key pair and an SSH key pair with the public key added to the cluster worker nodes.
