From a DevOps process standpoint, it is a good practice to keep changes to an application under version control. Which of the following allows changes to a Docker image to be stored in a version control system?
Answer: C
Explanation:
The option that allows changes to a Docker image to be stored in a version control system is: docker commit The docker commit command is used to create a new image from a container ' s changes. It takes a running container as input, captures the changes made to it, and creates a new image with those changes. This new image can then be tagged and pushed to a registry, or saved locally. By using docker commit, you can effectively capture the changes made to a container as a new image and store it in a version control system along with the Dockerfile and other project files. This allows for reproducibility and traceability of changes to the Docker image over time.

You are designing an automated integration testing strategy for a containerized microservice deployed to an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. The microservice ' s integration tests must write test events to an OCI Stream within a specific compartment. To comply with security mandates, you must avoid the use of hardcoded credentials, long-lived API signing keys, or manual token injection during the automated test execution. Which TWO configurations are required to securely authorize the test suite to access the OCI Streaming service? (Choose TWO.)
Answer: B,D
Explanation:
For OKE workloads running on managed worker nodes, OCI Instance Principals provide credential-free access to OCI APIs. Oracle documents creating a dynamic group containing the worker-node Compute instances, commonly using a matching rule based on instance.compartment.id, and then granting that dynamic group appropriate permissions through an IAM policy. Streaming permissions can authorize publishing to streams without embedding user credentials in application configuration. Hardcoded Auth Tokens violate the stated security requirement, root privileges do not bypass OCI IAM authentication, and security lists only control network traffic rather than service authorization. For modern enhanced OKE clusters, Oracle now provides Workload Identity for finer-grained pod-level authorization and recommends it where appropriate; however, among the options supplied, the documented instance-principal configuration is A and B.
NEW QUESTION # 63
Which option best defines microservices?
Answer: D
Explanation:
The correct answer is: " A finely tuned piece of software that performs a single or small collection of tasks. " Microservices are a software architectural approach where a system is decomposed into small, independent services that are responsible for performing a specific set of tasks. Each microservice is designed to be focused, finely tuned, and highly cohesive, handling a single or a small collection of related tasks. This granularity allows for better scalability, maintainability, and flexibility in building complex applications. The other options provided do not accurately define microservices: An open-source system for automating deployment, scaling, and management of containerized applications refers to a container orchestration tool like Kubernetes, which can be used to manage microservices but is not a definition of microservices itself. A statically typed and compiled language describes a type of programming language characteristic and is not specific to the concept of microservices. An organized collection of structured information or data, typically stored electronically in a computer system is a definition of a database or data storage system and is unrelated to microservices.

Which concept in OCI Queue is responsible for hiding a message from other consumers for a predefined amount of time after it has been delivered to a consumer?
Answer: D
Explanation:
Visibility timeout is the concept in OCI Queue that is responsible for hiding a message from other consumers for a predefined amount of time after it has been delivered to a consumer1. The visibility timeout can be set at the queue level when creating a queue, or it can be specified when consuming or updating messages1. If a consumer is having difficulty successfully processing a message, it can update the message to extend its invisibility1. If a message's visibility timeout is not extended, and the consumer does not delete the message, it returns to the queue1.Verified References: Overview of Queue
NEW QUESTION # 65
You are developing a cloud native serverless application where uploaded PDF documents inside an OCI Object Storage bucket must automatically trigger an OCI Function for text processing. You have created an OCI Events rule configured with the condition eventType: com.oraclecloud.objectstorage.createbucket matching the bucket ' s compartment. However, when test files are uploaded, the function does not trigger.
Which TWO actions must you perform to successfully implement and troubleshoot this event-driven integration?
Answer: B,D
Explanation:
Object-level state changes in OCI Object Storage donot emit Events by default. Oracle requires the bucket ' sEmit Object Eventscapability to be enabled before object create, update, or delete events are generated. In addition, the rule must use the correct event type. com.oraclecloud.objectstorage.createbucket represents creation of a bucket itself, whereas uploading a new object generates com.oraclecloud.objectstorage.
createobject. Therefore, the current rule can never match ordinary PDF uploads. Dynamic groups are not used to assign identities to buckets, Events does not require permission to read the actual object ' s contents, and no VCN Service Gateway is necessary for this native OCI service integration. Consequently, B and D are required.
