NEW QUESTION # 70
Your team has been tasked with debugging a Cloud Native application developed using the following Oracle Cloud Infrastructure (OCI) services: Object Storage, Events, Functions, API Gateway, and Autonomous Database. Which of these is NOT a valid option for troubleshooting issues in OCI? (Choose the best answer.)
Answer: B
Explanation:
To troubleshoot issues in OCI, the option that is not valid is: Trace performance issues in the Application Performance Monitoring service by enabling Function traces. While the Application Performance Monitoring service in OCI allows you to monitor and trace the performance of your applications, it is specifically designed for monitoring OCI Functions (serverless functions) and does not directly apply to all types of applications. The other options mentioned, such as configuring logs in the OCI Logging service, leveraging OCI Cloud Guard for debug logs, viewing service metrics in the OCI Monitoring service, and using OCI Service Connector Hub for log forwarding, are valid options for troubleshooting and monitoring applications in OCI.
NEW QUESTION # 71
Which token authentication policy configuration parameter should be defined when adjusting for potential clock synchronization differences between the external OAuth2 identity provider and the OCI API Gateway?
Answer: B
Explanation:
maxClockSkewInSeconds specifies the maximum expected difference between the system clock of the token issuer and the OCI API Gateway. Oracle documents this value as part of token/JWT authentication policy configuration. The gateway accounts for the configured skew when evaluating time-dependent JWT claims such as nbf (not before) and exp (expiration), preventing otherwise valid tokens from being rejected because of minor clock differences between systems. Oracle currently documents a valid range from 0 through 120 seconds for the JWT policy. maxCacheDurationInHours controls caching behavior rather than clock synchronization, while SSL verification relates to certificate validation. allowedClockVariance is not the documented OCI API Gateway property. Therefore, B is the correct configuration parameter.
NEW QUESTION # 72
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: A,B
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 # 73
You are configuring an Oracle Cloud Infrastructure Events rule to process lifecycle changes for both Object Storage objects and Compute instances within a single compartment. Which JSON filter attribute structure correctly groups multiple event types under a single filter condition?
Answer: A
Explanation:
Oracle Events uses the singular top-level field eventType to identify the type of event represented by an event message. When a rule must match more than one event type, Oracle explicitly documents placing multiple event-type strings in a JSON array assigned to eventType. Values within that array operate as alternatives, allowing the condition to match an event corresponding to any listed type. eventTypes, actionTypes, and filterType are not valid substitutes for the documented field. Likewise, concatenating event types into a single pipe-delimited or comma-delimited string does not create multiple event matches. Option D therefore implements the exact structure Oracle shows in its Events filtering examples for a rule covering multiple event types.
NEW QUESTION # 74
You deployed a Python application to an Oracle Container Engine for Kubernetes (OKE) cluster. However, while testing you found a bug, which you rectified and then created a new Docker image. You now need to ensure that if this new image does not work once deployed, you should be able to roll back to the previous version. Using kubect1, which strategy should you use?
Answer: C
Explanation:
A rolling update is a deployment strategy that gradually replaces the old version of an application with the new version without any downtime4. OKE supports rolling updates by using the kubectl rollout command4. A rolling update allows you to roll back to the previous version if something goes wrong with the new version4.
Therefore, using a rolling update strategy with kubectl ensures that you can roll back to the previous version of your Python application if the new image does not work once deployed.Verified References: Deploy Oracle Container Engine for Kubernetes
