Question 221

A company has a photo sharing social networking application. To provide a consistent experience for users, the company performs some image processing on the photos uploaded by users before publishing on the application. The image processing is implemented using a set of Python libraries.

The current architecture is as follows:

The image processing Python code runs in a single Amazon EC2 instance and stores the processed images in an Amazon S3 bucket named ImageBucket. The front-end application, hosted in another bucket, loads the images from ImageBucket to display to users.

With plans for global expansion, the company wants to implement changes in its existing architecture to be able to scale for increased demand on the application and reduce management complexity as the application scales. Which combination of changes should a solutions architect make? (Choose two.)

Question 225

A Solutions Architect is designing a highly available and reliable solution for a cluster of Amazon EC2 instances. The Solutions Architect must ensure that any EC2 instance within the cluster recovers automatically after a system failure. The solution must ensure that the recovered instance maintains the same IP address.

How can these requirements be met?

Create an AWS Lambda script to restart any EC2 instances that shut down unexpectedly.

Create an Auto Scaling group for each EC2 instance that has a minimum and maximum size of 1.

Create a new t2.micro instance to monitor the cluster instances. Configure the t2.micro instance to issue an aws ec2 reboot-instances command upon failure.

Create an Amazon CloudWatch alarm for the StatusCheckFailed_System metric, and then configure an EC2 action to recover the instance.

Question 226

A bank is designing an online customer service portal where customers can chat with customer service agents. The portal is required to maintain a 15-minute RPO or RTO in case of a regional disaster. Banking regulations require that all customer service chat transcripts must be preserved on durable storage for at least 7 years, chat conversations must be encrypted inflight, and transcripts must be encrypted at rest. The Data Loss Prevention team requires that data at rest must be encrypted using a key that the team controls, rotates, and revokes.

Which design meets these requirements?

The chat application logs each chat message into Amazon CloudWatch Logs. A scheduled AWS Lambda function invokes a CloudWatch Logs CreateExportTask every 5 minutes to export chat transcripts to Amazon S3. The S3 bucket is configured for cross-region replication to the backup region. Separate AWS KMS keys are specified for the CloudWatch Logs group and the S3 bucket.

The chat application logs each chat message into two different Amazon CloudWatch Logs groups in two different regions, with the same AWS KMS key applied. Both CloudWatch Logs groups are configured to export logs into an Amazon Glacier vault with a 7-year vault lock policy with a KMS key specified.

The chat application logs each chat message into Amazon CloudWatch Logs. A subscription filter on the CloudWatch Logs group feeds into an Amazon Kinesis Data Firehose which streams the chat messages into an Amazon S3 bucket in the backup region. Separate AWS KMS keys are specified for the CloudWatch Logs group and the Kinesis Data Firehose.

The chat application logs each chat message into Amazon CloudWatch Logs. The CloudWatch Logs group is configured to export logs into an Amazon Glacier vault with a 7-year vault lock policy. Glacier cross-region replication mirrors chat archives to the backup region. Separate AWS KMS keys are specified for the CloudWatch Logs group and the Amazon Glacier vault.

Question 229

A company is using an Amazon EMR cluster to run its big data jobs. The cluster’s jobs are invoked by AWS Step Functions Express Workflows that consume various Amazon Simple Queue Service (Amazon SQS) queues. The workload of this solution is variable and unpredictable. Amazon CloudWatch metrics show that the cluster's peak utilization is only 25% at times and that the cluster sits idle the rest of the time. A solutions architect must optimize the costs of the cluster without negatively impacting the time it takes to run the various jobs. What is the MOST cost-effective solution that meets these requirements?

Modify the EMR cluster by turning on automatic scaling of the core nodes and task nodes with a custom policy that is based on cluster utilization. Purchase Reserved Instance capacity to cover the master node.

Modify the EMR cluster to use an instance fleet of Dedicated On-Demand Instances for the master node and core nodes, and to use Spot Instances for the task nodes. Define target capacity for each node type to cover the load.

Purchase Reserved Instances for the master node and core nodes. Terminate all existing task nodes in the EMR cluster.

Modify the EMR cluster to use capacity-optimized Spot Instances and a diversified task fleet. Define target capacity for each node type with a mix of On-Demand Instances and Spot Instances.

Question 230

A solutions architect needs to migrate 50 TB of NFS data to Amazon S3. The files are on several NFS file servers on corporate network. These are dense file systems containing tens of millions of small files. The system operators have configured the file interface on an AWS Snowball Edge device and are using a shell script to copy data. Developers report that copying the data to the Snowball Edge device is very slow. The solutions architect suspects this may be related to the overhead of encrypting all the small files and transporting them over the network. Which changes can be made to speed up the data transfer?

Cluster two Snowball Edge devices together to increase the throughput of the devices.

Change the solution to use the S3 Adapter instead of the file interface on the Snowball Edge device.

Increase the number of parallel copy jobs to increase the throughput of the Snowball Edge device.

Connect directly to the USB interface on the Snowball Edge device and copy the files locally.
