Oracle Updated 1z0-1084-26 Exam Questions and Answers by savanna

OCI Secret Management requires asymmetric encryption keywhen a Vault key is selected to encrypt secret contents. Oracle explicitly states that asymmetric keys cannot be used for secret encryption. Of the listed algorithms, AES is the supported symmetric key-shape algorithm; RSA and ECC are asymmetric algorithms, while 3DES is not an available OCI Vault master-key shape for this purpose. OCI Vault supports AES symmetric keys for encryption and decryption, typically using a 256-bit key length. Therefore, when creating a customer-managed key intended to protect OCI secrets, the appropriate key algorithm is Advanced Encryption Standard (AES). This requirement ensures that secret bundles can be encrypted and decrypted through the Vault cryptographic service.

Explanation

The two correct differences between continuous delivery and continuous deployment in the DevOps lifecycle are: Continuous delivery is a process that initiates deployment manually, while continuous deployment is based on automating the deployment process. In continuous delivery, the software is ready for deployment, but the decision to deploy is made manually by a human. On the other hand, continuous deployment automates the deployment process, and once the software passes all the necessary tests and quality checks, it is automatically deployed without human intervention. Continuous delivery utilizes automatic deployment to a development environment, while continuous deployment involves automatic deployment to a production environment. In continuous delivery, the software is automatically deployed to a development or staging environment for further testing and validation. However, the actual deployment to the production environment is performed manually. In continuous deployment, the software is automatically deployed to the production environment, eliminating the need for manual intervention in the deployment process. These differences highlight the level of automation and human involvement in the deployment process between continuous delivery and continuous deployment approaches in the DevOps lifecycle.

Option D is invalid because OCI Streaming imposes a maximum request/message payload size of approximately1 MiB, not 10 MB. Oracle ' s current Streaming documentation also verifies the remaining statements. Stream retention can be configured between 24 hours and seven days. Cursors are temporary consumption pointers and expire five minutes after being returned by the service. Private endpoints can be configured at the stream-pool level using a private subnet in a VCN, keeping producer and consumer traffic from traversing the public internet. These limits affect application architecture directly: payloads larger than the Streaming request limit normally need to be chunked or stored externally with only a reference carried in the message. Therefore, D is the only invalid statement.

OCI dynamic groups identify Compute instances using the documented instance.id attribute, making B valid. Oracle Container Registry documentation also shows manage repos as a policy capable of authorizing image pushes within a specified compartment, making D the sufficient policy among the supplied choices. container.instance is not a valid Compute-instance matching variable, while inspect repos provides only discovery-level permissions. use repos does not supply the repository update permissions required for pushing images. For stricter production least privilege, Oracle additionally documents conditioning a manage repos policy to specific permissions such as REPOSITORY_READ, REPOSITORY_UPDATE, and REPOSITORY_CREATE; however, that granular variant is not offered among these choices. Therefore, B and D are the correct selections.
