A company is planning to launch a new steady-state workload on AWS that must be

accessible 24 hours a day, 7 days a week.

What is the MOST cost-effective Amazon EC2 pricing option?

• On-Demand Instances
• Spot Instances
• Dedicated Hosts
• Reserved Instances

Which AWS services can be used to move data from on-premises data centers to AWS? (Select

TWO.)

• AWS Snowball

• Amazon API Gateway

• AWS Database Migration Service (AWS DMS)

• Amazon ElastiCache

• AWS Lambda

A company must store critical business data in Amazon S3 with a backup to another

AWS Region

How can this be achieved?

• Storing data in a local server

• Amazon S3 Same Replication

• Amazon S3 Cross-Region Replication

• Using a third-party cloud storage provider

Under the shared responsibility model, which of thefollowing tasks are the responsibility of the customer?

(Choose two.)

• Deploying hardware in different Availability Zones.

• Replacing failed hard disk drives.

• Encrypting data in transit and at rest.

• Managing the VPC network access control lists.

• Maintaining the underlying Amazon EC2 hardware.

Under the AWS shared responsibility model, AWS is responsible for what combination of the

following? (Select TWO)

• Maintaining the hardware that constitutes the cloud

• Updating Amazon EC2 security groups

• Setting and maintaining Amazon S3 access permissions.

• Managing physical access to AWS data centers

• Configuring network ACLS

Which AWS service can be used to automatically scale an application up and down without making capacity

planning decisions?

• AWS CloudTrail

• AWS CloudFormation
• AWS Lambda
• Amazon EBS

Which of the following services is in the category of AWS serverless platform?

• Cloud Watch

• Cloud Trail

• AWS Lambda
• IBM Cloud Functions

A company is migrating from an on-premises infrastructure to the AWS Cloud. One of the company’s

applications stores files on a Windows file server farm that uses Distributed File System Replication

(DFSR) to keep data in sync. A solutions architect needs to replace the file server farm.

Which service should the solutions architect use?

• Amazon S3
• Amazon FSx for Windows File Server
• Amazon EFS
• Amazon Glacier

A company’s application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The

instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. On the first day of

every month at midnight, the application becomes much slower when the month-end financial calculation

batch executes. This causes the CPU utilization of the EC2 instances to immediately peak to 100%, which

disrupts the application.

What should a solutions architect recommend to ensure the application is able to handle the workload and

avoid downtime?

• Make a scheduled scalinig policy in ASG

• Move the application to a different cloud provider
• Manually increase the CPU capacity of the existing instances
• Shut down the entire application during the month-end financial calculation batch

How can a customer increase security to AWS account logons?

• Use the same password for all accounts
• Disable multi-factor authentication (MFA)
• Use easily guessable passwords
• Enable multi-factor authentication (MFA) and use strong, unique passwords
