C, D Correct answer

C, D Correct answer

C. Check if the file exists in the specified bucket location.
D. Check if correct permissions are configured for the S3 user.

### **Explanation:**
When an **Amazon S3 data stream** fails to refresh with a "**NO FILE FOUND**" error message, the likely causes are related to either the **file location** or **permissions**. Here's what to check:

1. **C. Check if the file exists in the specified bucket location**
- Ensure that the file you're expecting to stream from **Amazon S3** is **present** in the **specified bucket and path**.
- If the file doesn't exist at the specified location or has been moved/renamed, Data Cloud will not be able to find it.

2. **D. Check if correct permissions are configured for the S3 user**
- The **S3 user** (the account connecting Data Cloud to Amazon S3) must have the **correct permissions** (read access) to the specified S3 bucket and file.
- Check the **IAM policies** for the S3 user and ensure they grant necessary **read** permissions for the specific file and bucket.

### **Why Not the Other Options?**
- **A. Check if correct permissions are configured for the Data Cloud user**
- Permissions for the **Data Cloud user** are less likely to be the cause of this issue since the error specifically mentions the file not being found in S3. The permissions issue is more likely on the **S3 side**.
- **B. Check if the Amazon S3 data source is enabled in Data Cloud Setup**
- While it is important that the data source is configured, this error is more likely related to the file's **location or permissions** rather than whether the source is enabled....
