NEW QUESTION # 48
You are developing an asynchronous, decoupled billing microservice that consumes payment messages from an Oracle Cloud Infrastructure (OCI) Queue. You notice that some corrupted payment payloads are causing the consumer application to fail and restart repeatedly, leaving the messages unprocessed and blocking the queue. To isolate these toxic messages, you want to redirect them to a Dead Letter Queue (DLQ) after 5 failed delivery attempts.
Which TWO configuration steps or characteristics must you apply to implement this solution?
Answer: B,E
Explanation:
The supplied Word answer key requires correction here. Current Oracle Queue documentation explicitly states that adead letter queue is automatically created when a queue is created. Therefore, option C is correct and option B is not. Oracle also provides the Maximum delivery attempts setting, which controls how many unsuccessful deliveries can occur before a problematic message is transferred to the DLQ. Setting that value to 5 implements the requested retry threshold. No separately provisioned target queue is required, consumer groups are optional and unrelated to enabling DLQ functionality, and administrators do not create an IAM policy authorizing a source queue resource to write to its automatically associated DLQ. Consequently, the verified current answer isA, C, not the Word file ' s A, B.
NEW QUESTION # 49
You are developing a polyglot serverless application using Oracle Functions. Which language cannot be used to write your function code?
Answer: B
Explanation:
Oracle Functions does not currently support PL/SQL as a language for writing function code. PL/SQL is a procedural language used in Oracle Database for developing stored procedures, triggers, and other database- related code. However, Oracle Functions supports several other popular programming languages such as Go, Node.js, Python, and Java, allowing developers to choose the language that best suits their application requirements and their familiarity with the language. While PL/SQL is powerful for working with the Oracle Database, it is not an option for writing function code in the Oracle Functions serverless architecture.
NEW QUESTION # 50
Which is ONE of the differences between a microservice and a serverless function?
Answer: D
Explanation:
The correct answer is: Microservices are used for long running operations while serverless functions are used for short running operations. One of the key differences between microservices and serverless functions is the duration of their execution. Microservices are typically designed to handle long-running operations and may continuously run and process requests as part of a larger system. They are often deployed and managed as long-lived services. On the other hand, serverless functions are designed to handle short-lived operations or tasks that execute in response to specific events or triggers. They are event-driven and execute only when invoked, providing a lightweight and ephemeral computing model. Serverless functions are often used for executing small, isolated pieces of code without the need for managing infrastructure or scaling concerns.
While both microservices and serverless functions can be stateless or stateful depending on the specific implementation, the key distinction lies in the typical duration and execution pattern of these components within an application architecture.
NEW QUESTION # 51
What is the difference between continuous delivery and continuous deployment in the DevOps methodology?
(Choose the best answer.)
Answer: A
Explanation:
The two correct differences between continuous delivery and continuous deployment in the DevOps lifecycle are: Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process. In continuous delivery, the software is ready for deployment, but the decision to deploy is made manually by a human. On the other hand, continuous deployment automates the deployment process, and once the software passes all the necessary tests and quality checks, it is automatically deployed without human intervention. Continuous delivery utilizes automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment. In continuous delivery, the software is automatically deployed to a development or staging environment for further testing and validation. However, the actual deployment to the production environment is performed manually. In continuous deployment, the software is automatically deployed to the production environment, eliminating the need for manual intervention in the deployment process. These differences highlight the level of automation and human involvement in the deployment process between continuous delivery and continuous deployment approaches in the DevOps lifecycle.
NEW QUESTION # 52
Your cloud-native banking microservice retrieves API tokens stored in OCI Vault. To meet strict security compliance standards, you must configure secret rules on these vault secrets. The security policies mandate that the secret contents must automatically expire and have their retrieval blocked 30 days after creation, and any previously used token content must never be allowed for reuse, even if the older secret version containing that content has been deleted. Which TWO configurations must you specify within the secret rules to satisfy these compliance requirements?
Answer: B,E
Explanation:
OCI Vault provides both Secret Expiry Rules and Secret Reuse Rules. secret_version_expiry_interval uses an ISO 8601 duration, so P30D establishes a 30-day validity period. Setting is_secret_content_retrieval_blocked_on_expiry to true ensures secret contents cannot be retrieved after expiry, satisfying the first requirement. For the second requirement, a SECRET_REUSE_RULE prevents previously used secret contents from being reused across versions. Oracle ' s SDK documentation confirms that is_enforced_on_deleted_secret_versions=true extends that restriction even when the previous secret version has been deleted. Setting either Boolean to false would weaken the stated controls.
HSM_PURGE_RULE is not one of the documented OCI Vault secret-rule types. Therefore, C and D jointly satisfy both requirements.
