A developer is creating an AWS Lambda function that needs credentials to connect to an Amazon RDS for MySQL database. An Amazon S3 bucket currently stores the credentials. The developer needs to improve the existing solution by implementing credential rotation and secure storage. The developer also needs to provide integration with the Lambda function.
Which solution should the developer use to store and retrieve the credentials with the LEAST management overhead?

1. A. Store the credentials in AWS Systems Manager Parameter Stor
2. B. Select the database that the parameter will acces
3. C. Use the default AWS Key Management Service (AWS KMS) key to encrypt the paramete
4. D. Enable automatic rotation for the paramete
5. E. Use the parameter from Parameter Store on the Lambda function to connect to the database.
6. F. Encrypt the credentials with the default AWS Key Management Service (AWS KMS) ke
7. G. Store the credentials as environment variables for the Lambda functio
8. H. Create a second Lambda function to generate new credentials and to rotate the credentials by updating the environment variables of the first Lambda functio
9. I. Invoke the second Lambda function by using an Amazon EventBridge rule that runs on a schedul
10. J. Update the database to use the new credential
11. K. On the first Lambda function, retrieve the credentials from the environment variable
12. L. Decrypt the credentials by using AWS KMS, Connect to the database.
13. M. Store the credentials in AWS Secrets Manage
14. N. Set the secret type to Credentials for Amazon RDS databas
15. O. Select the database that the secret will acces
16. P. Use the default AWS Key Management Service(AWS KMS) key to encrypt the secre
17. Q. Enable automatic rotation for the secre
18. R. Use the secret from Secrets Manager on the Lambda function to connect to the database.
19. S. Encrypt the credentials by using AWS Key Management Service (AWS KMS). Store the credentials in an Amazon DynamoDB tabl
20. T. Create a second Lambda function to rotate the credential
21. . Invoke the second Lambda function by using an Amazon EventBridge rule that runs on a schedul
22. . Update the DynamoDB tabl
23. . Update the database to use the generated credential
24. . Retrieve the credentials from DynamoDB with the first Lambda functio
25. . Connect to the database.

Correct Answer: C

A company is using an AWS Lambda function to process records from an Amazon Kinesis data stream. The company recently observed slow processing of the records. A developer notices that the iterator age metric for the function is increasing and that the Lambda run duration is constantly above normal.
Which actions should the developer take to increase the processing speed? (Choose two.)

1. A. Increase the number of shards of the Kinesis data stream.
2. B. Decrease the timeout of the Lambda function.
3. C. Increase the memory that is allocated to the Lambda function.
4. D. Decrease the number of shards of the Kinesis data stream.
5. E. Increase the timeout of the Lambda function.

Correct Answer: AC
