Question 7

A company wants to replace its call system with a solution built using AWS managed services. The company call center would like the solution to receive calls, create contact flows, and scale to handle growth projections. The call center would also like the solution to use deep learning capabilities to recognize the intent of the callers and handle basic tasks, reducing the need to speak an agent. The solution should also be able to query business applications and provide relevant information back to calls as requested.
Which services should the Solution Architect use to build this solution? (Choose three.)

A. Amazon Rekognition to identity who is calling.

B. Amazon Connect to create a cloud-based contact center.

C. Amazon Alexa for Business to build conversational interface.

D. AWS Lambda to integrate with internal systems.

E. Amazon Lex to recognize the intent of the caller.

F. Amazon SQS to add incoming callers to a queue.

Correct Answer:BDE

Question 8

A Solutions Architect needs to design a highly available application that will allow authenticated users to stay connected to the application even when there are underlying failures
Which solution will meet these requirements?

A. Deploy the application on Amazon EC2 instances Use Amazon Route 53 to forward requests to the EC2 Instances Use Amazon DynamoDB to save the authenticated connection details

B. Deploy the application on Amazon EC2 instances in an Auto Scaling group Use an internet-facing Application Load Balancer to handle requests Use Amazon DynamoDB to save the authenticated connection details

C. Deploy the application on Amazon EC2 instances in an Auto Scaling group Use an internet-facing Application Load Balancer on the front end Use EC2 instances to save the authenticated connectiondetails

D. Deploy the application on Amazon EC2 instances in an Auto Scaling group Use an internet-facing Application Load Balancer on the front end Use EC2 instances hosting a MySQL database to save the authenticated connection details

Correct Answer:B

Question 9

A Solutions Architect has been asked to look at a company’s Amazon Redshift cluster, which has quickly become an integral part of its technology and supports key business process. The Solutions Architect is to increase the reliability and availability of the cluster and provide options to ensure that if an issue arises, the cluster can either operate or be restored within four hours.
Which of the following solution options BEST addresses the business need in the most cost-effective manner?

A. Ensure that the Amazon Redshift cluster has been set up to make use of Auto Scaling groups with the nodes in the cluster spread across multiple Availability Zones.

B. Ensure that the Amazon Redshift cluster creation has been template using AWS CloudFormation so it can easily be launched in another Availability Zone and data populated from the automated Redshift back-ups stored in Amazon S3.

C. Use Amazon Kinesis Data Firehose to collect the data ahead of ingestion into Amazon Redshift and create clusters using AWS CloudFormation in another region and stream the data to both clusters.

D. Create two identical Amazon Redshift clusters in different regions (one as the primary, one as the secondary). Use Amazon S3 cross-region replication from the primary to secondary). Use Amazon S3 cross-region replication from the primary to secondary region, which triggers an AWS Lambda function to populate the cluster in the secondary region.

Correct Answer:B
https://aws.amazon.com/redshift/faqs/?nc1=h_ls Q: What happens to my data warehouse cluster availability and data durability if my data warehouse cluster's Availability Zone (AZ) has an outage? If your Amazon Redshift data warehouse cluster's Availability Zone becomes unavailable, you will not be able to use your cluster until power and network access to the AZ are restored. Your data warehouse cluster's data is preserved so you can start using your Amazon Redshift data warehouse as soon as the AZ becomes available again. In addition, you can also choose to restore any existing snapshots to a new AZ in the same Region. Amazon Redshift will restore your most frequently accessed data first so you can resume queries as quickly as possible.

Question 11

A company is migrating its marketing website and content management system from an on-premises data center to AWS. The company wants the AWS application to be developed in a VPC with Amazon EC2 instances used for the web servers and an Amazon RDS instance for the database.
The company has a runbook document that describes the installation process of the on-premises system. The company would like to base the AWS system on the processes referenced in the runbook document. The runbook document describes the installation and configuration of the operating systems, network settings, the website, and content management system software on the servers. After the migration is complete, the company wants to be able to make changes quickly to take advantage of other AWS features.
How can the application and environment be deployed and automated in AWS, while allowing for future changes?

A. Update the runbook to describe how to create the VPC, the EC2 instances, and the RDS instance for the application by using the AWS Consol

B. Make sure that the rest of the steps in the runbook are updated to reflect any changes that may come from the AWS migration.

C. Write a Python script that uses the AWS API to create the VPC, the EC2 instances, and the RDS instance for the applicatio

D. Write shell scripts that implement the rest of the steps in the runboo

E. Have the Python script copy and run the shell scripts on the newly created instances to complete the installation.

F. Write an AWS CloudFormation template that creates the VPC, the EC2 instances, and the RDS instance for the applicatio

G. Ensure that the rest of the steps in the runbook are updated to reflect any changes that may come from the AWS migration.

H. Write an AWS CloudFormation template that creates the VPC, the EC2 instances, and the RDS instance for the applicatio

I. Include EC2 user data in the AWS CloudFormation template to install and configure the software.

Correct Answer:D

Question 12

While debugging a backend application for an loT system that supports globally distributed devices a Solutions Architect notices that stale data is occasionally being sent to user devices. Devices often share data, and stale data does not cause issues in most cases However device operations are disrupted when a device reads the stale data after an update
The global system has multiple identical application stacks deployed In different AWS Regions If a user device travels out of its home geographic region it will always connect to the geographically closest AWS Region to write or read data The same data is available in all supported AWS Regions using an Amazon DynamoDB global table
What change should be made to avoid causing disruptions in device operations'?

A. Update the backend to use strongly consistent read

B. Update the devices to always write to and read from their home AWS Region

C. Enable strong consistency globally on a DynamoDB global table Update the backend to use strongly consistent reads

D. Switch the backend data store to Amazon Aurora MySQL with cross-region replicas Update the backend to always write to the master endpoint

E. Select one AWS Region as a master and perform all writes in that AWS Region only Update the backend to use strongly consistent reads
