Select 3You are developing an application using the AWS SDK for Python (Boto3) to upload files to an S3 bucket. During testing, an error is raised when attempting to upload a file. Which of the following exceptions should you handle to ensure the application can deal with common issues during the upload process?
- A
botocore.exceptions.ClientError
- B
botocore.exceptions.EndpointConnectionError

FileNotFoundError
- D
IndexError
- E
ValueError
Show answer and explanation
Correct answers: A, B, C
Explanation
When working with AWS SDKs, it is essential to handle various exceptions that may arise depending on the operation. For uploading files to S3, common exceptions include ClientError for issues with the API call, EndpointConnectionError for network or endpoint-related problems, and FileNotFoundError for missing files. Properly handling these exceptions ensures your application is robust and can gracefully handle errors during runtime.
- A. Correct.
This is correct. ClientError is a common exception raised by the AWS SDK when there is an issue with the request, such as invalid credentials, missing permissions, or an incorrect bucket name.
- B. Correct.
This is correct. EndpointConnectionError is raised when the SDK cannot connect to the specified endpoint, which could happen due to network issues or incorrect configuration.
- C. Correct.
This is correct. FileNotFoundError occurs when the file specified for the upload does not exist, which is a common issue during file operations.
- D. Incorrect.
This is incorrect. IndexError is not relevant to AWS SDK operations or file uploads. It pertains to attempting to access an invalid index in a Python list.
- E. Incorrect.
This is incorrect. ValueError is not related to the types of exceptions commonly raised by AWS SDKs during file uploads.
