NEW QUESTION # 74
Which configuration parser type is mandatory when setting up a custom log with the OCI Unified Monitoring Agent if no log structure parsing is required?
Answer: C
Explanation:
Oracle explicitly states that theNONEparser type is required when configuring the Unified Monitoring Agent even when no particular parsing of the incoming log structure is desired. The agent configuration still requires a parser declaration so it knows how the input should be handled. NONE allows the log content to be collected without applying structural parsing such as JSON, SYSLOG, regular-expression, or Apache-style parsing. Oracle ' s SDK model also lists NONE as a supported parserType value. RAW, DEFAULT, and UNSTRUCTURED are not the documented parser-type identifiers for this purpose. Consequently, administrators configuring custom logs that should be ingested without parsing must explicitly select or specify NONE, making C the correct answer.
NEW QUESTION # 75
You are a developing a microservices application that will be a consumer of the Oracle Cloud Infrastructure (OCI) Streaming service. Which API method should you use to read and process a stream?
Answer: D
Explanation:
The correct API method to read and process a stream in the Oracle Cloud Infrastructure (OCI) Streaming service is " GetMessages " . When consuming messages from a stream in OCI Streaming, you use the " GetMessages " API method. This method allows you to retrieve a batch of messages from the stream for processing. You can specify parameters such as the number of messages to retrieve, the maximum size of the messages, and the timeout for the request. By using the " GetMessages " API method, you can retrieve messages from the stream and then process them in your microservices application. This allows you to consume and handle the data in real-time as it becomes available in the stream. The " GetMessages " method provides flexibility in how you consume and process the messages, enabling you to implement custom logic and workflows based on your specific application requirements.
NEW QUESTION # 76
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 # 77
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,D
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.
NEW QUESTION # 78
Which pattern is used to decompose a monolithic application by gradually replacing specific parts of its functionality with microservices?
Answer: A
Explanation:
The Strangler Pattern is specifically designed for incremental modernization of a monolithic application.
Oracle ' s cloud-native guidance describes it as gradually replacing portions of a monolith with microservices over time, minimizing disruption and avoiding the operational risk of a complete " big bang " rewrite. New functionality or migrated capabilities are implemented as independent services while remaining functionality continues to operate in the existing monolith. Eventually, the legacy application can be retired after its responsibilities have been progressively replaced. The Saga Pattern instead manages distributed transactions, the Sidecar Pattern places supporting functionality beside an application workload, and the Transactional Outbox Pattern provides reliable coordination between database changes and event publishing. Therefore, the pattern matching gradual monolith decomposition is the Strangler Pattern.
