Question 112

- (Exam Topic 1)
A solutions architect is evaluating the reliability of a recently migrated application running on AWS. The front end is hosted on Amazon S3 and accelerated by Amazon CloudFront. The application layer is running in a stateless Docker container on an Amazon EC2 On-Demand Instance with an Elastic IP address. The storage layer is a MongoDB database running on an EC2 Reserved Instance in the same Availability Zone as the application layer.
Which combination of steps should the solutions architect take to eliminate single points of failure with minimal application code changes? (Select TWO.)

A. Create a REST API in Amazon API Gateway and use AWS Lambda functions as the application layer.
B. Create an Application Load Balancer and migrate the Docker container to AWS Fargate.
C. Migrate the storage layer to Amazon DynamoD8.
D. Migrate the storage layer to Amazon DocumentD8 (with MongoDB compatibility).
E. Create an Application Load Balancer and move the storage layer to an EC2 Auto Scaling group.

Question 113

Your company hosts a social media site supporting users in multiple countries. You have been asked to provide a highly available design tor the application that leverages multiple regions tor the most recently accessed content and latency sensitive portions of the wet) site The most latency sensitive component of the application involves reading user preferences to support web site personalization and ad selection. In addition to running your application in multiple regions, which option will support this appIication’s requirements?

A. Serve user content from S3. CIoudFront and use Route53 latency-based routing between ELBs in each region Retrieve user preferences from a local DynamoDB table in each region and leverage SQS to capture changes to user preferences with SOS workers for propagating updates to each table.
B. Use the S3 Copy API to copy recently accessed content to multiple regions and serve user content from S3. C|oudFront with dynamic content and an ELB in each region Retrieve user preferences from an EIasticCache cluster in each region and leverage SNS notifications to propagate user preference changes to a worker node in each region.
C. Use the S3 Copy API to copy recently accessed content to multiple regions and serve user content from S3 CIoudFront and Route53 latency-based routing Between ELBs In each region Retrieve user preferences from a DynamoDB table and leverage SQS to capture changes to user preferences with SOS workers for propagating DynamoDB updates.
D. Serve user content from S3. C|oudFront with dynamic content, and an ELB in each region Retrieve user preferences from an EIastiCache cluster in each region and leverage Simple Workflow (SWF) to manage the propagation of user preferences from a centralized OB to each EIastiCache cluster.

Correct Answer:A

Question 114

You are designing a personal document-archMng solution for your global enterprise with thousands of employee. Each employee has potentially gigabytes of data to be backed up in this archMng solution. The solution will be exposed to the employees as an application, where they can just drag and drop their files to the archMng system. Employees can retrieve their archives through a web interface. The corporate network has high bandwidth AWS Direct Connect connectMty to AWS.
You have a regulatory requirement that all data needs to be encrypted before being uploaded to the cloud.
How do you implement this in a highly available and cost-efficient way?

A. Manage encryption keys on-premises in an encrypted relational databas
B. Set up an on-premises server with sufficient storage to temporarily store files, and then upload them to Amazon S3, providing a client-side master key.
C. Mange encryption keys in a Hardware Security ModuIe (HSM) appliance on-premises serve r with sufficient storage to temporarily store, encrypt, and upload files directly into Amazon Glacier.
D. Nlanage encryption keys in Amazon Key Management Service (KMS), upload to Amazon Simple Storage Service (S3) with client-side encryption using a KMS customer master key ID, and configure Amazon S3 lifecycle policies to store each object using the Amazon Glacier storage tier.
E. Manage encryption keys in an AWS C|oudHSNI applianc
F. Encrypt files prior to uploading on the employee desktop, and then upload directly into Amazon Glacier.

Correct Answer:C

Question 115

You have a periodic Image analysis application that gets some files In Input analyzes them and tor each file writes some data in output to a ten file the number of files in input per day is high and concentrated in a few hours of the day.
Currently you have a server on EC2 with a large EBS volume that hosts the input data and the results it takes almost 20 hours per day to complete the process
What services could be used to reduce the elaboration time and improve the availability of the solution?

A. S3 to store I/O file
B. SQS to distribute elaboration commands to a group of hosts working in paralle
C. Auto scaling to dynamically size the group of hosts depending on the length of the SQS queue
D. EBS with Provisioned IOPS (PIOPS) to store I/O file
E. SNS to distribute elaboration commands to a group of hosts working in parallel Auto Scaling to dynamically size the group of hosts depending on the number of SNS notifications
F. S3 to store I/O files, SNS to distribute evaporation commands to a group of hosts working in paralle
G. Auto scaling to dynamically size the group of hosts depending on the number of SNS notifications
H. EBS with Provisioned IOPS (PIOPS) to store I/O files SQS to distribute elaboration commands to a group of hosts working in parallel Auto Scaling to dynamically size the group ot hosts depending on the length of the SQS queue.
