Oracle Cloud Infrastructure Developer Professional Sample Questions (Q83-Q88):

NEW QUESTION # 83
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?

A. A separate target queue must be manually created first and then selected as the designated Dead Letter Queue.
B. A dead letter queue is automatically created when you create the queue, so no manual DLQ resource creation is required.
C. Modify the " Maximum delivery attempts " setting of the queue to 5.
D. Configure an IAM policy specifically allowing the source queue to write to a target DLQ queue.
E. Enable consumer groups on the queue because DLQ functionality is only supported when utilizing consumer groups.

Answer: B,C

Explanation:
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.

NEW QUESTION # 84
Which TWO statements accurately describe an Oracle Functions application? (Choose two.)

A. A common context to store configuration variables that are available to all functions in the application.
A Docker image containing all the functions that share the same configuration.
B. An application based on Oracle Functions, Oracle Cloud Infrastructure (OCI) Events, and OCI API Gateway services.
C. A Docker image containing all the functions that share the same configuration.
D. A small block of code invoked in response to an OCI Events service.A logical group of functions.

Answer: A,D

Explanation:
The correct statements are: A common context to store configuration variables that are available to all functions in the application. A Docker image containing all the functions that share the same configuration. A logical group of functions.Explanation: An Oracle Functions application provides a common context for functions within the application. It allows you to store configuration variables that are accessible by all the functions in the application. Functions within the same application can share the same Docker image, which contains the common configuration and dependencies. An Oracle Functions application serves as a logical group that organizes related functions. Functions within the same application can be managed collectively, and they can interact and share resources within the application context.

NEW QUESTION # 85
Your company has recently deployed a new web application that uses Oracle Functions. Your manager instructs you to implement monitoring metrics to manage your systems more effectively. You know that Oracle Functions automatically monitors functions on your behalf and reports metrics via Oracle Cloud Infrastructure (OCI) Monitoring. Which TWO metrics are collected and made available by this feature?
(Choose two.)

A. Number of times a function is invoked
B. Amount of RAM used by a function
C. Number of times a function Is removed
D. Length of time a function runs
E. Amount of CPU used by a function

Answer: B,E

Explanation:
The correct answers are: Amount of RAM used by a function: Oracle Functions collects and reports the amount of memory (RAM) used by a function during its execution. This metric helps in monitoring and optimizing the resource consumption of functions. Length of time a function runs: Oracle Functions captures and provides the duration of function executions. This metric allows you to track the performance and responsiveness of your functions and identify any potential bottlenecks or delays. These metrics provide valuable insights into the resource utilization and performance of your functions, enabling you to monitor and optimize their behavior in the Oracle Cloud Infrastructure (OCI) environment.

NEW QUESTION # 86
Your organization is developing serverless applications with Oracle Functions. Many functions will need to store state data in a database, which will require using appropriate credentials. However, your corporate security standards mandate encryption of secret information, such as database passwords. How would you address this security requirement?

A. Leverage application-level configuration variables to store passwords because they are automatically encrypted by Oracle Functions.
B. Use the OCI Vault service to auto-encrypt the password and then set an application-level configuration variable to reference the auto-decrypted password inside your function container.
C. Encrypt the password using the OCI Vault service and then decrypt this password in your function code with the generated key.
D. Use OCI Console to enter the password in the function configuration section in the provided input field.

Answer: C

Explanation:
The best way to store and use secret information, such as database passwords, in Oracle Functions is to use the OCI Vault service. The OCI Vault service provides encryption and decryption capabilities for sensitive data. You can use the OCI Vault service to encrypt the password and store it as an application-level configuration variable. Then, you can use the generated key to decrypt the password in your function code when you need to access the database.

NEW QUESTION # 87
You are building a cloud native serverless travel application with multiple Oracle Functions in Java, Python, and Node.js. You need to build and deploy these functions to a single application named travel-app. Which command will help you complete this task successfully?

A. fn function deploy app travel-app--all
B. fn app --app travel-app deploy --ext java pyljs
C. fn app deploy --app travel-app --all
D. fn deploy--app travel-app --all

Answer: D

Explanation:
The correct answer is: fn deploy --app travel-app --allExplanation: To build and deploy multiple Oracle Functions as part of a single application named " travel-app, " you can use the fn deploy command with the appropriate options. The command fn deploy --app travel-app --all is the correct syntax. Here ' s what each part of the command does: fn deploy: This command is used to deploy functions and applications in Oracle Functions. --app travel-app: This option specifies the application name as " travel-app, " indicating that you want to deploy functions to this application. --all: This option indicates that you want to deploy all the functions within the application. By using fn deploy --app travel-app --all, you can build and deploy all the functions in your travel application across different programming languages (Java, Python, and Node.js) to the " travel-app " application in Oracle Functions.
