The Twelve-Factor methodology requires configuration to be separated from application code and backing services to be treated as attached resources. Oracle ' s Twelve-Factor guidance specifically recommends keeping configuration outside the Docker image and supplying deployment-specific values through the environment. This allows the same application artifact to move between development, test, and production without rebuilding it. Kubernetes ConfigMaps or environment variables implement this principle effectively. The backing-services factor similarly treats databases, queues, caches, and external services as replaceable resources referenced through configuration rather than hardcoded dependencies. Consequently, switching a database or message broker should require configuration changes rather than application-code changes. Hardcoding credentials or environment-specific values violates configuration separation, while sharing one database across environments is not required for dev/prod parity. Therefore, B and D are correct.

(OPT) iad.ocir.io/myproject/heyoci/myapp:latest The three valid tags for an image named myapp in the heyoci namespace of the Oracle Cloud Infrastructure Registry (OCIR) in the us-ashburn-1 (iad) region are: iad.ccir.io/heyoci/myapp:latest This tag specifies the latest version of the myapp image in the heyoci namespace in the iad region. iad.ocir.io/heyoci/myapp:0.0.2-beta This tag specifies version 0.0.2-beta of the myapp image in the heyoci namespace in the iad region. us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta This tag specifies version 0.0.2-beta of the myapp image in the heyoci namespace in the us-ashburn-1 region. The other options mentioned are not valid tags for the given scenario: us-ashburn-1.ocir.io/heyoci/myapp:0.0.2-beta (incorrect format, missing the namespace) iad.ocir.io/myproject/heyoci/myapp:latest (incorrect format, incorrect order of namespace and project) us-ashburn-1.ocir.io/myproject/heyoci/myapp:latest (incorrect format, incorrect order of namespace and project) The correct format for tagging an image in OCIR is < region > .ocir.io/ < namespace > / < repository > : < tag > .

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.

Explanation

The two statements that are NOT valid regarding the Oracle Cloud Infrastructure (OCI) Streaming service are: A stream can be configured with either a public or a private endpoint with support for customer managed encryption keys. This statement is not valid because the OCI Streaming service currently supports only private endpoints. Customer managed encryption keys are not currently supported for OCI Streaming. OCI Streaming can support up to 2,000 requests per second to each partition. This statement is not valid because the throughput of a stream is not defined by the partition in terms of requests per second. The throughput of a stream is defined in terms of data input and output rates. Each partition provides 1 MB/sec data input and 2 MB/sec data output, but it does not correspond to a specific number of requests per second. The other statements are valid: OCI Streaming stores all data for 24 hours by default, but that can be extended up to 7 days. Although OCI Streaming automatically encrypts all data while in transit, it is the developer ' s responsibility to encrypt data at rest, if needed.
