Question: 1
Your organization uses a federated identity provider to login to your Oracle Cloud Infrastructure (OCI) environment. As a developer, you are writing a script to automate some operation and want to use OCI CLI to do that. Your security team doesn't allow storing private keys on local machines.
How can you authenticate with OCI CLI?
A. Run oci setup keys and provide your credentials
B. Run oci session refresh ---profile
C. Run oci session authenticate and provide your credentials
D. Run oci setup oci-cli-rc ---file path/to/target/file
Answer : C

Question: 3
You have been asked to create a stateful application deployed in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) that requires all of your worker nodes to mount and write data to persistent volumes.
Which two OCI storage services should you use?
A. Use OCI File Services as persistent volume.
B. Use GlusterFS as persistent volume.
C. Use OCI Block Volume backed persistent volume.
D. Use open source storage solutions on top of OCI.
E. Use OCI Object Storage as persistent volume.

Answer: AC
Question: 4
You are a consumer of Oracle Cloud Infrastructure (OCI) Streaming service. Which API should you use to read and process the stream?
A. ListMessages
B. GetMessages
C. GetObject
D. ReadMessages
Explanation:
Answer: B
https://docs.cloud.oracle.com/en-us/iaas/Content/Streaming/Concepts/streamingoverview.htm Building consumers to read and process messages from a stream using the GetMessages API . How Streaming Works:
The Streaming service provides a robust, scalable mechanism that you can use to produce and consume high volumes of data between application components.
Here's how Streaming works: a producer publishes messages to a stream, which is an append-only log. These messages are distributed among the partitions using the message's key.
Streams are divided into a number of partitions for scalability. Partiti ns allow you to distribute a stream by splitting messages across multiple nodes (or brokers). Each partiti n can be placed on a separate machine to allow multiple consumers to read a stream in parallel. Multiple consumers can read from any partiti n regardless of where the partiti n is hosted.
A consumer can read messages from one or more streams. Each message within a stream is marked with an offset value, so a consumer can pick up where it left off if it is interrupted.
You can use the Streaming service by: A.Creating a stream using the Console or API.
B.Using a producer to publish data to the stream.
C. Building consumers to read and process messages from a stream using the GetMessages API . .

Question: 5
Which two handle Oracle Functions authentication automatically?
A. Oracle Cloud Infrastructure SDK
B. cURL
C. Oracle Cloud Infrastructure CLl
D. Signed HTTP Request
E. Fn Project CLI
Explanation:
Answer: CE
If you use the Fn Project CLI or the Oracle Cloud Infrastructure CLI to invoke a function, authentication is handled for you. See Using the Fn Project CLI to Invoke Functions and Using the Oracle Cloud Infrastructure CLI to Invoke Functions.
If you use an Oracle Cloud Infrastructure SDK to invoke a function, you can use the SDK to handle authentication. See Using SDKs to Invoke Functions.
If you make a signed HTTP request to a function's invoke endpoint, you'll have to handle authentication yourself by including a signature and the OCID of the compartment to which the function belongs in the request header
Fn Project CLI you can create an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure and specify --provider oracle This option enables Oracle Functions to perform authentication and authorization using Oracle Cloud Infrastructure request signing, private keys, user groups, and policies that grant permissions to those user groups.
