A company’s legacy application is currently relying on a single-instance Amazon RDS MySQL database
without encryption. Due to new compliance requirements, all existing and new data in this database
must be encrypted. How should this be accomplished?
A. Create an Amazon S3 bucket with server-side encryption enabled. Move all the data to Amazon S3.
Delete the RDS instance.
B. Enable RDS Multi-AZ mode with encryption at rest enabled. Perform a failover to the standby instance
to delete the original instance.
C. Take a Snapshot of the RDS instance. Create an encrypted copy of the snapshot. Restore the RDS
instance from the encrypted snapshot.
D. Create an RDS read replica with encryption at rest enabled. Promote the read replica to master and
switch the over to the new master. Delete the old RDS instance. C. Take a Snapshot of the RDS
instance. Create an encrypted copy of the snapshot. Restore the RDS instance from the encrypted
snapshot.
A manufacturing company wants to implement predictive maintenance on its machinery equipment. The
company will install thousands of IoT sensors that will send data to AWS in real time. A solutions
architect is tasked with implementing a solution that will receive events in an ordered manner for each
1
,machinery asset and ensure that data is saved for further processing at a later time. Which solution
would be MOST efficient?
A. Use Amazon Kinesis Data Streams for real-time events with a partition for each equipment asset. Use
Amazon Kinesis Data Firehose to save data to Amazon S3.
B. Use Amazon Kinesis Data Streams for real-time events with a shard for each equipment asset. Use
Amazon Kinesis Data Firehose to save data to Amazon EBS.
C. Use an Amazon SQS FIFO queue for real-time events with one queue for each equipment asset.
Trigger an AWS Lambda function for the SQS queue to save data to Amazon EFS.
D. Use an Amazon SQS standard queue for real-time events with one queue for each equipment asset.
Trigger an AWS Lambda function for the SQS queue to save data to Amazon S3. A. Use Amazon
Kinesis Data Streams for real-time events with a partition for each equipment asset. Use Amazon Kinesis
Data Firehose to save data to Amazon S3.
A company’s website runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The
website has a mix of dynamic and static content. Users around the globe are reporting that the website
is slow. Which set of actions will improve website performance for users worldwide?

Amazon Route 53 record to point to the CloudFront distribution.
B. Create a latency-based Amazon Route 53 record for the ALB. Then launch new EC2 instances with
larger instance sizes and register the instances with the ALB.
C. Launch new EC2 instances hosting the same web application in different Regions closer to the users.
Then register instances with the same ALB using cross-Region VPC peering.
D. Host the website in an Amazon S3 bucket in the Regions closest to the users and delete the ALB and
EC2 instances. Then update an Amazon Route 53 record to point to the S3 bucket. A. Create an
Amazon CloudFront distribution and configure the ALB as an origin. Then update the Amazon Route 53
record to point to the CloudFront distribution.
A company has been storing analytics data in an Amazon RDS instance for the past few years. The
