B.

a single subnet inside the VPC.

C.

a placement group.

D.

a single Availability Zone.

Question 58

Question 59

An application team uses an Amazon Aurora MySQL DB cluster with one Aurora Replica. The application team notices that the application read performance degrades when user connections exceed 200. The number of user connections is typically consistent around 180. with occasional sudden increases above 200 connections. The application team wants the application to automatically scale as user demand increases or decreases.

Which solution will meet these requirements?

Options:

A.

Migrate to a new Aurora multi-master DB cluster. Modify the application database connection string.

B.

Modify the DB cluster by changing to serverless mode whenever user connections exceed 200.

C.

Create an auto scaling policy with a target metric of 195 DatabaseConnections

D.

Modify the DB cluster by increasing the Aurora Replica instance size.

Question 60

A SysOps administrator needs to give users the ability to upload objects to an Amazon S3 bucket. The SysOps administrator creates a presigned URL and provides the URL to a user, but the user cannot upload an object to the S3 bucket. The presigned URL has not expired, and no bucket policy is applied to the S3 bucket.

Which of the following could be the cause of this problem?

Options:

A.

The user has not properly configured the AWS CLI with their access key and secret access key.

B.

The SysOps administrator does not have the necessary permissions to upload the object to the S3 bucket.

C.

The SysOps administrator must apply a bucket policy to the S3 bucket to allow the user to upload the object.

D.

The object already has been uploaded through the use of the presigned URL, so the presigned URL is no longer valid.
