NEW QUESTION # 175
Which resolution rule does an Oracle Cloud Infrastructure API Gateway apply when determining the routing target for an incoming request that matches multiple overlapping route paths within a deployment?
Answer: D
Explanation:
The Word source identifiesLongest path matchas the answer, meaning the more specific matching route takes precedence when a request could satisfy multiple path patterns. This is consistent with the general routing principle that more specific path patterns take precedence over broader prefixes. Oracle ' s current OCI API Gateway documentation confirms that deployment routes are defined using URL path patterns and that path parameters and wildcard segments can be used for matching requests to backends. However, the currently published OCI API Gateway pages retrieved for verification do not explicitly state a universal "longest path match" precedence rule for overlapping deployment routes. Therefore, C is the answer recorded in the supplied source, but this particular rule is not stated verbatim in the current OCI API Gateway documentation located during verification.
NEW QUESTION # 176
You are deploying a containerized database application on a host using the standard Docker engine. To prevent data loss when the container instance is destroyed or updated, you must configure a storage mechanism that isolates application data from the volatile container layer and guarantees persistence. Which TWO statements or approaches correctly describe Docker storage components that satisfy this requirement?
Answer: B,C
Explanation:
Persistent container data must be stored outside the container ' s ephemeral writable layer. Docker volumes provide Docker-managed storage that remains independently available from the lifecycle of an individual container. Bind mounts provide another persistence mechanism by mapping a specified host file or directory directly into the container. Oracle ' s Docker documentation demonstrates both data volumes and host-path mounts for externalizing files from containers and preserving them independently. The writable container layer is removed with the container, a tmpfs mount stores data in volatile memory rather than persistent disk, and Docker image layers are immutable and cannot receive normal runtime database writes. Therefore, Docker volumes and bind mounts are the two valid persistence approaches described.
NEW QUESTION # 177
Your organization has mandated strict IAM policy isolation for microservices accessing an Oracle Cloud Infrastructure (OCI) Queue named payment-queue in a compartment named prod-payment-compartment. A producer microservice deployed on an OCI Compute instance needs to publish transaction messages into the queue, but corporate security dictates that this microservice must not have permission to view queue configurations, delete queues, or read/consume messages. You have created a dynamic group named payment- producer-dg that contains the Compute instance hosting the producer microservice.
Which IAM policy statement must you write to satisfy this security requirement with the least privilege?
Answer: A
NEW QUESTION # 178
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,E
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 # 179
A developer has created another version of a microservice and wants 10% of the traffic to flow towards it for testing purposes. The application is already configured using OCI (Oracle Cloud Infrastructure) Service Mesh. Which of the following steps is the right approach to achieve this goal?
Answer: D
