NEW QUESTION # 87
You are designing the persistence layer for a multi-service financial application where each microservice must completely isolate its private persistent data to enforce a bounded context. Which database configuration strategy should you implement within a multi-tenant Oracle Database to satisfy this requirement with the lowest operational overhead?
Answer: D
Explanation:
Oracle specifically recommends the multitenant database model for microservices because multiple Pluggable Databases can reside within one Container Database while retaining logical isolation. Oracle ' s microservices architecture guidance identifies PDBs as a strong persistence choice forbounded-context isolation, security, and high availability. Allocating a PDB per microservice isolates that service ' s private database objects while avoiding the infrastructure and operational overhead of provisioning an entire VM database system for every service. Shared schemas or shared tables weaken service autonomy and create tight coupling between bounded contexts. Because a CDB can host multiple isolated PDBs while sharing common database infrastructure and administration, option B best combines isolation with operational efficiency.
NEW QUESTION # 88
Which is the smalled unit of Kubernetes architecture?
Answer: C
Explanation:
The smallest unit of Kubernetes architecture is a Pod. A Pod is a logical grouping of one or more containers that are deployed together on the same host and share the same network namespace, storage, and other resources. It represents the smallest deployable unit in Kubernetes and is used to encapsulate and manage one or more closely related containers. Containers within a Pod are scheduled and deployed together, allowing them to communicate and share resources efficiently.
NEW QUESTION # 89
Which statement is NOT valid regarding the OCI Vulnerability Scanning service (VSS) for container images stored in Oracle Cloud Infrastructure Registry (OCIR)?
Answer: D
Explanation:
Oracle explicitly states that youcannot create a container image target using a repository that is already specified in another target. Therefore, a single OCIR repository cannot simultaneously be assigned to multiple Vulnerability Scanning targets simply to apply different recipes, making A invalid. Oracle also documents that a newly created target scans a configurable initial number of existing images, with one image being the default, and subsequently scans newly pushed images. Scan results are stored in the compartment containing the Vulnerability Scanning target, even when the repository resides elsewhere. Before creating a target, administrators must also grant Vulnerability Scanning permission to pull images from Container Registry.
Consequently, B, C, and D accurately describe documented VSS behavior.
NEW QUESTION # 90
Your development team wants to configure API Gateway request validation to shield an upstream backend microservice from ill-formed API calls. You want to test the validation rules in your staging environment first without blocking any non-compliant client requests, and you want to ensure the gateway checks that a mandatory HTTP header is present. Which TWO configurations should you apply to your API Gateway deployment specification to meet this requirement?
Answer: B,D
Explanation:
OCI API Gateway request validation supportsEnforcing, Permissive, and Disabledvalidation modes. In Permissive mode, requests are validated and failures are recorded, but even non-compliant requests continue to the backend, making it appropriate for testing the impact of validation before enforcing it. Oracle also supports explicit header validation rules in which a header can be marked required: true. Enforcing mode instead blocks requests that fail validation and returns a 4xx response. No dynamic group is required for API Gateway to validate standard HTTP headers, and request.auth relates to authentication context rather than header-presence validation. Therefore, A and C directly satisfy both stated requirements.
NEW QUESTION # 91
Which is NOT a valid backend-type option available when configuring an Oracle Cloud Infrastructure (OCI) API Gateway Deployment?
Answer: C
Explanation:
When configuring an OCI API Gateway deployment, you need to specify the backend type for each route in your API deployment specification3. The backend type determines how the API gateway handles requests to that route and forwards them to the appropriate backend service3. The following backend types are valid options for an OCI API Gateway deployment3:
* HTTP_BACKEND: The API gateway forwards requests to an HTTP or HTTPS URL as the backend service.
* ORACLE_FUNCTIONS_BACKEND: The API gateway invokes an Oracle Functions function as the backend service.
* STOCK_RESPONSE_BACKEND: The API gateway returns a stock response without invoking any backend service. ORACLE STREAMS_BACKEND is not a valid backend type for an OCI API Gateway deployment. Oracle Streams is a fully managed, scalable, and durable messaging service that you can use to ingest and consume large amounts of data in real-time4. However, Oracle Streams is not supported as a backend service for an OCI API Gateway deployment.
