質問 # 173
What is the maximum allowable size for a secret bundle stored in the Oracle Cloud Infrastructure (OCI) Vault service?
正解：B
解説：
Oracle Secret Management documentation explicitly specifies that themaximum allowable size for a secret bundle is 25 KB. This limit applies when creating a secret or creating a new version of an existing secret.
When using the OCI Console, administrators can enter plain-text secret contents and the Console performs the required Base64 encoding. When communicating directly with the service through supported APIs or CLI operations, secret contents must be supplied in the required encoded form. Secrets are intended for security- sensitive values such as passwords, API tokens, certificates, and configuration credentials rather than arbitrary large files. Payloads exceeding the supported secret-bundle size should therefore be redesigned, divided appropriately, or stored using a service suited to larger objects. Consequently, B is the verified Oracle limit.
質問 # 174
With the volume of communication that can happen between different components in cloud-native applications, it is vital to not only test functionality, but also service resiliency. Which statement is true regarding service resiliency?
正解：A
解説：
The correct answer is: " Resiliency is about recovering from failures without downtime or data loss. " Service resiliency, in the context of cloud-native applications, is the ability of a service or system to recover from failures and continue functioning without downtime or data loss. It involves designing and implementing mechanisms to handle failures, such as network outages, hardware failures, or software errors, in a way that minimizes the impact on the overall system. The goal of resiliency is to ensure that the application or service can continue to operate and provide a certain level of functionality, even in the face of failures. This typically involves techniques such as redundancy, fault tolerance, and graceful degradation. By implementing resiliency measures, a cloud-native application can recover and adapt to failures, maintain availability, and preserve data integrity. The other statements are not accurate regarding service resiliency: Resiliency is not about not bringing a service to a functioning state after a failure. Instead, it is about recovering from failures and ensuring continued functionality. Resiliency is not about avoiding failures entirely. While it is desirable to prevent failures, resiliency focuses on the ability to handle and recover from failures when they do occur.
Resiliency testing is not limited to a test environment. It is important to test and validate the resiliency measures in both test environments and production environments to ensure the application can effectively handle failures in real-world scenarios.
質問 # 175
Which statement is NOT valid regarding custom metrics and the OCI Monitoring PostMetricData API?
正解：B
解説：
Statement C is invalid because Oracle permits custom metrics to be postedas frequently as every second. The one-minute value applies to the minimum aggregation interval when metric data is subsequently queried, not to the ingestion frequency. Oracle also verifies the remaining statements. PostMetricData requires timestamps to be less than two hours in the past and less than ten minutes in the future. Custom namespaces must not use reserved prefixes such as oci_ or oracle_. The API additionally allows a maximum of 20 dimensions per metric group in a single posting operation. Therefore, interpreting one minute as the minimum interval between raw metric submissions incorrectly confuses ingestion frequency with Monitoring ' s aggregation
/query interval. Option C is consequently the NOT valid statement.
質問 # 176
Which master encryption key shape algorithm must be used when configuring a customer-managed key to encrypt a secret in the Oracle Cloud Infrastructure (OCI) Vault?
正解：A
解説：
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.
質問 # 177
You are developing an asynchronous, decoupled billing microservice that consumes payment messages from an Oracle Cloud Infrastructure (OCI) Queue. You notice that some corrupted payment payloads are causing the consumer application to fail and restart repeatedly, leaving the messages unprocessed and blocking the queue. To isolate these toxic messages, you want to redirect them to a Dead Letter Queue (DLQ) after 5 failed delivery attempts.
Which TWO configuration steps or characteristics must you apply to implement this solution?
正解：A、B
解説：
The supplied Word answer key requires correction here. Current Oracle Queue documentation explicitly states that adead letter queue is automatically created when a queue is created. Therefore, option C is correct and option B is not. Oracle also provides the Maximum delivery attempts setting, which controls how many unsuccessful deliveries can occur before a problematic message is transferred to the DLQ. Setting that value to 5 implements the requested retry threshold. No separately provisioned target queue is required, consumer groups are optional and unrelated to enabling DLQ functionality, and administrators do not create an IAM policy authorizing a source queue resource to write to its automatically associated DLQ. Consequently, the verified current answer isA, C, not the Word file ' s A, B.
