NEW QUESTION # 61
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?
Answer: C
Explanation:
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.

You are developing a distributed application and you need a call to a path to always return a specific JSON content deploy an OCI API Gateway with the below API deployment specification. What is the correct value for type? { " routes " : [{ " path " : " /hello " , " methods " : [ " Get " ), " backend " : { " type " : " ----------------
" , " status " : 200, " headers " : [{ " name " : " Content-Type " , " value " : " application/json " }] " body " : "
{\ " myjson\ " : \ " consistent response\ " } " }}]}
Answer: C
Explanation:
The correct value for the " type " field in the API deployment specification is " STOCK_RESPONSE_BACKEND " . By setting the " type " to " STOCK_RESPONSE_BACKEND " , you are indicating that the backend for the specified route should return a pre-defined response. This type of backend is commonly used when you want a specific response to be returned consistently, regardless of the actual backend service implementation. In this case, the API deployment specification is configured to have a single route with the path " /hello " and the method " GET " . The backend section specifies the type as " STOCK_RESPONSE_BACKEND " . Additionally, it defines the response status code as 200, sets the " Content-Type " header to " application/json " , and provides the JSON content in the " body " field. Using this configuration, any request to the " /hello " path with the " GET " method will always receive a consistent JSON response with the content " { " myjson " : " consistent response " } " .

You have created a repository in Oracle Cloud Infrastructure Registry (OCIR) in the us-ashburn-1 (iad) region in your tenancy with the heyoci namespace. Which three are valid tags for an image named myapp? (Choose three.)
Answer: A,C,F
Explanation:
(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 > .
NEW QUESTION # 64
What are the TWO main reasons you would choose to implement a serverless architecture? (Choose two.)
Answer: C,E
Explanation:
The two main reasons to choose a serverless architecture are: Automatic horizontal scaling: Serverless architectures allow for automatic scaling of resources based on demand. The infrastructure automatically provisions and scales resources as needed, ensuring that applications can handle varying workloads efficiently. This eliminates the need for manual scaling and optimizes resource utilization. Reduced operational cost: Serverless architectures follow a pay-per-use model, where you are billed only for the actual execution time and resources consumed by your functions. This leads to cost savings as you don ' t have to pay for idle resources. Additionally, serverless architectures remove the need for managing and maintaining servers, reducing operational overhead and associated costs.Explanation: No need for integration testing:
Integration testing is still necessary in serverless architectures to ensure that functions integrate correctly with other components and services. Serverless functions can interact with various event sources, databases, and APIs, and testing is required to verify the integration points. Improved in-function state management:
Serverless architectures typically encourage stateless functions that operate on short-lived requests or events.
While there are mechanisms to manage state within a function, serverless architectures are designed to be stateless by default, promoting scalability and fault tolerance. Easier to run long-running operations:
Serverless functions are generally designed for short-lived operations rather than long-running tasks. If you have a requirement for long-running operations, a serverless architecture may not be the ideal choice, as it has execution time limits and may not provide the necessary resources for extended execution.
NEW QUESTION # 65
Which statement is NOT valid regarding context variables used for dynamic backend routing in Oracle Cloud Infrastructure API Gateway?
Answer: B
Explanation:
Oracle API Gateway documents the context-variable selectors available for dynamic backend routing.
Supported selectors include request.auth[ < key > ], request.headers[ < key > ], request.host, request.path[ < key > ], request.query[ < key > ], request.subdomain[ < key > ], and usage-plan information. Therefore, headers, authentication claims, and query parameters can all participate directly in backend-selection rules.
Although API Gateway can expose the request body to amulti-argument authorizer function, Oracle does not list request.body[ < key > ] as a supported selector for dynamic backend routing. Its presence in that separate authorizer context does not make it a dynamic-routing selector capable of parsing arbitrary JSON fields.
Consequently, A, B, and C describe supported routing context variables, while D incorrectly extends the routing model to request-body key selection.
