NEW QUESTION # 14
Which statement is NOT valid regarding the comparison between cloud-native and cloud-based applications?
Answer: C
Explanation:
Option C reverses a fundamental cloud-native characteristic. Oracle describes cloud-native applications as being designed for automated scale-up and scale-down in response to changing workload demand.
Technologies including containers, Kubernetes, serverless architectures, microservices, and automated DevOps processes are specifically intended to reduce manual infrastructure management. Oracle also identifies scalability, resilience, reduced operational overhead, and cost optimization through cloud consumption models as major cloud-native advantages. Applications migrated to cloud infrastructure without substantial architectural modernization can retain monolithic dependencies, fixed capacity assumptions, and manual provisioning practices. Therefore, claiming that cloud-native applications require manual host provisioning while cloud-based applications automatically scale by default is technically inverted. C is consequently the NOT valid statement among the available choices.
NEW QUESTION # 15
What is the maximum allowable size for a secret bundle stored in the Oracle Cloud Infrastructure (OCI) Vault service?
Answer: D
Explanation:
Oracle Secret Management documentation explicitly specifies that themaximum allowable size for a secret bundle is 25 KB. This limit applies when creating a secret or creating a new version of an existing secret.
When using the OCI Console, administrators can enter plain-text secret contents and the Console performs the required Base64 encoding. When communicating directly with the service through supported APIs or CLI operations, secret contents must be supplied in the required encoded form. Secrets are intended for security- sensitive values such as passwords, API tokens, certificates, and configuration credentials rather than arbitrary large files. Payloads exceeding the supported secret-bundle size should therefore be redesigned, divided appropriately, or stored using a service suited to larger objects. Consequently, B is the verified Oracle limit.
NEW QUESTION # 16
Which statement is NOT valid regarding testing methodologies for cloud native applications?
Answer: D
Explanation:
Statement D is NOT valid. Oracle ' s cloud application architecture guidance explicitly describes integration testing as validating interactions and data flow between components, modules, and services. In a cloud-native architecture, those interactions commonly occur through network-based APIs, service endpoints, databases, and messaging systems. Oracle recommends test environments that resemble production rather than restricting integration testing to isolated developer workstations. Unit testing does focus on individual units of code and typically isolates dependencies. API mocking can emulate unavailable dependent services, while performance testing evaluates responsiveness, scalability, and stability under varying workloads such as load and stress conditions. Therefore, the claim that integration testing is exclusively local and does not validate network communication contradicts the actual purpose of integration testing.
NEW QUESTION # 17
You developed a microservices-based application that runs in an Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) cluster. Your security team wants to use SSL termination for this application.
What should you do to create a secure SSL termination for this application using the fewest steps possible?
Answer: A
Explanation:
The correct answer is: " Create a self-signed certificate and its corresponding key. Create a Kubernetes secret using the certificate and the key. Then add these annotations to the Kubernetes service: annotations: service.
beta.kubernetes.io/oci-load-balancer-ssl-ports: ' 443 ' service.beta.kubernetes.io/oci-load-balancer-tls-secret:
ssl certificate-secret. " To create a secure SSL termination for your microservices-based application running in an OCI Container Engine for Kubernetes (OKE) cluster, you can follow these steps: Create a self-signed certificate and its corresponding key: Generate a self-signed SSL certificate and its private key using a tool like OpenSSL. Create a Kubernetes secret: Create a Kubernetes secret using the certificate and key obtained in the previous step. This secret will securely store the certificate and key within the Kubernetes cluster. Add annotations to the Kubernetes service: Modify the Kubernetes service that exposes your application and add the following annotations to enable SSL termination: annotations: service.beta.kubernetes.io/oci-load- balancer-ssl-ports: ' 443 ' (specify the SSL port as 443) annotations: service.beta.kubernetes.io/oci-load- balancer-tls-secret: ssl certificate-secret (specify the name of the Kubernetes secret containing the certificate and key) By following these steps, you can create a secure SSL termination for your application using a self- signed certificate and Kubernetes secret. The annotations added to the Kubernetes service ensure that the SSL port is configured correctly and the TLS secret is utilized for SSL termination when traffic reaches the load balancer. The other options provided are not the most suitable approaches for achieving secure SSL termination in an OCI Container Engine for Kubernetes (OKE) cluster: Adding annotations related to the OCI load balancer SSL secret key is not the correct approach for SSL termination in this scenario. Using Let ' s Encrypt to generate a self-signed certificate and configuring it on the OCI Load Balancer is not necessary when you can create and manage the SSL certificate within the Kubernetes cluster using a Kubernetes secret.
NEW QUESTION # 18
Which design pattern is used when a microservice needs to atomically perform a database write and send a notification event using a single local transaction?
Answer: C
Explanation:
The Transactional Outbox pattern addresses the distributed-system dual-write problem by recording both the business-state change and an outgoing event within one local database transaction. Rather than attempting to atomically update a database and independently publish to a messaging platform, the service writes the event into an outbox table alongside the business update. Because both database modifications occur within the same transaction, they commit or roll back together. A separate publisher subsequently reads the outbox and sends the event to the messaging infrastructure. Oracle ' s current microservices architecture documentation explicitly identifies Transactional Outbox as the pattern for sending a message and performing a data manipulation operation within a single local transaction. Saga and CQRS address different distributed-system concerns.
