Question 1

A company is receiving semi-structured and structured data from different sources every day. The Solutions Architect plans to use big data processing frameworks to analyze vast amounts of data and access it using various business intelligence tools and standard SQL queries.

Which of the following provides the MOST high-performing solution that fulfills this requirement?

Options :

A : Create an Amazon EC2 instance and store the processed data in Amazon EBS.

B : Create an Amazon EMR cluster and store the processed data in Amazon Redshift.

C : Use AWS Glue and store the processed data in Amazon S3.

D : Use Amazon Kinesis Data Analytics and store the processed data in Amazon DynamoDB.

Answer: B

Question 2

A company plans to host a web application in an Auto Scaling group of Amazon EC2 instances. The application will be used globally by users to upload and store several types of files. Based on user trends, files that are older than 2 years must be stored in a different storage class. The Solutions Architect of the company needs to create a cost-effective and scalable solution to store the old files yet still provide durability and high availability.

Which of the following approach can be used to fulfill this requirement? (Select TWO.)

Options :

A :

Use Amazon EBS volumes to store the files. Configure the Amazon Data Lifecycle Manager (DLM) to schedule snapshots of the volumes after 2 years.

B : Use Amazon EFS and create a lifecycle policy that will move the objects to Amazon EFS-IA after 2 years.

C : Use Amazon S3 and create a lifecycle policy that will move the objects to Amazon S3 Standard-IA after 2 years.

D : Use Amazon S3 and create a lifecycle policy that will move the objects to Amazon S3 Glacier after 2 years.

E : Use a RAID 0 storage configuration that stripes multiple Amazon EBS volumes together to store the files. Configure the Amazon Data Lifecycle Manager (DLM) to schedule snapshots of the volumes after 2 years.

Answer: C,D

Question 3

An online events registration system is hosted in AWS and uses ECS to host its front-end tier and an RDS configured with Multi-AZ for its database tier. What are the events that will make Amazon RDS automatically perform a failover to the standby replica? (Select TWO.)

Options :

A : Compute unit failure on secondary DB instance

B : Storage failure on primary

C :

Loss of availability in primary Availability Zone

D : In the event of Read Replica failure

E : Storage failure on secondary DB instance

Answer: B,C

Question 4

A company is launching a new application deployed on an Amazon Elastic Container Service (Amazon ECS) cluster and is using the Fargate launch type for ECS tasks. The company is monitoring CPU and memory usage because it is expecting high traffic to the application upon its launch. However, the company wants to reduce costs when utilization decreases.

What should a solutions architect recommend?

Options :

A : Use Amazon EC2 Auto Scaling to scale at certain periods based on previous traffic patterns

B : Use an AWS Lambda function to scale Amazon ECS based on metric breaches that trigger an Amazon CloudWatch alarm

C : Use Amazon EC2 Auto Scaling with simple scaling policies to scale when ECS metric breaches trigger an Amazon CloudWatch alarm

D : Use AWS Application Auto Scaling with target tracking policies to scale when ECS metric breaches trigger an Amazon CloudWatch alarm

Answer: D

Question 5

A company has a service that reads and writes large amounts of data from an Amazon S3 bucket in the same AWS Region. The service is deployed on Amazon EC2 instances within the private subnet of a VPC. The service communicates with Amazon S3 over a NAT gateway in the public subnet. However, the company wants a solution that will reduce the data output costs.

Which solution will meet these requirements MOST cost-effectively?

Options :

A : Provision a dedicated EC2 NAT instance in the public subnet. Configure the route table for the private subnet to use the elastic network interface of this instance as the destination for all S3 traffic.

B : Provision a dedicated EC2 NAT instance in the private subnet. Configure the route table for the public subnet to use the elastic network interface of this instance as the destination for all S3 traffic.

C : Provision a VPC gateway endpoint. Configure the route table for the private subnet to use the gateway endpoint as the route for all S3 traffic.

D : Provision a second NAT gateway. Configure the route table for the private subnet to use this NAT gateway as the destination for all S3 traffic.
