Questions # 1:

A company wants to use Amazon Workspaces in combination with thin client devices to replace aging desktops. Employees use the desktops to access applications that work with clinical trial data. Corporate security policy states that access to the applications must be restricted to only company branch office locations. The company is considering adding an additional branch office in the next 6 months.

Questions # 3:

A company is migrating a legacy application from an on-premises data center to AWS. The application consists of a single application server and a Microsoft SQL

Server database server. Each server is deployed on a VMware VM that consumes 500 TB of data across multiple attached volumes.

The company has established a 10 Gbps AWS Direct Connect connection from the closest AWS Region to its on-premises data center. The Direct Connect connection is not currently in use by other services.

Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime? (Choose two.)

A company wants to run a custom network analysis software package to inspect traffic as traffic leaves and enters a VPC. The company has deployed the solution by using AWS Cloud Formation on three Amazon EC2 instances in an Auto Scaling group. All network routing has been established to direct traffic to the EC2 instances.

Whenever the analysis software stops working, the Auto Scaling group replaces an instance. The network routes are not updated when the instance replacement occurs.

Which combination of steps will resolve this issue? {Select THREE.)

In the Cloud Formation template, write a condition that updates the network routes when a replacement instance is launched.

Questions # 5:

A company has a sales system that stores transactions as .csv files in an Amazon S3 bucket. The S3 bucket is configured to use S3 Intelligent-Tiering. Most of the .csv files are between 64 KB and 100 KB in size. All rows and columns of the .csv files must be read when the data is processed. The company must keep the data for 5 years.

The company stores several million xsv files every day. The company must minimize the cost of storing and querying the xsv files.

The company wants to use AWS managed services where possible and does not want to rewrite the application. A solutions architect needs to implement a solution to resolve scaling issues and minimize licensing costs as the application scales.

Which solution will meet these requirements MOST cost-effectively?

Options:

Questions # 8:

A solutions architect needs to assess a newly acquired company’s portfolio of applications and databases. The solutions architect must create a business case to migrate the portfolio to AWS. The newly acquired company runs applications in an on-premises data center. The data center is not well documented. The solutions architect cannot immediately determine how many applications and databases exist. Traffic for the applications is variable. Some applications are batch processes that run at the end of each month.

The solutions architect must gain a better understanding of the portfolio before a migration to AWS can begin.

Questions # 9:

A company deploys workloads in multiple AWS accounts. Each account has a VPC with VPC flow logs published in text log format to a centralized Amazon S3 bucket. Each log file is compressed with gzjp compression. The company must retain the log files indefinitely.

A security engineer occasionally analyzes the togs by using Amazon Athena to query the VPC flow logs. The query performance is degrading over time as the number of ingested togs is growing. A solutions architect: must improve the performance of the tog analysis and reduce the storage space that the VPC flow logs use.

Which solution will meet these requirements with the LARGEST performance improvement?

Options:

Create an AWS Lambda function to decompress the gzip flies and to compress the tiles with bzip2 compression. Subscribe the Lambda function to an s3: ObiectCrealed;Put S3 event notification for the S3 bucket.

The company has configured AWS Backup to run every 4 hours on several Amazon EFS mount points in the eu-west-2 Region. The backups are stored in the default vault. The company needs a disaster recovery (DR) plan that restores into the eu-west-1 Region and a specific recovery account. The backups must be encrypted at all times. Which solution will meet these requirements?

Redirect the backups to the new backup vault. Configure a key policy statement to allow access to the key from the recovery account. Schedule a cross-account backup plan to the recovery account.

Create an Amazon S3 bucket. Create a new multi-Region customer managed KMS key to encrypt the S3 bucket data. Schedule a copy job from the backup vault that copies the data to the S3 bucket. Configure cross-account access for the recovery account to the S3 bucket. Schedule a second copy job in the recovery account to copy the data from the S3 bucket into the default vault.

Configure AWS DataSync to copy the EFS data to eu-west-1 in the source account. In the recovery account, create a new backup vault. Encrypt the data by using an AWS managed KMS key. In the source account, schedule a cross-account backup plan to the recovery account's vault in eu-west-1.

Questions # 11:

A company built an application based on AWS Lambda deployed in an AWS CloudFormation stack. The last production release of the web application introduced an issue that resulted in an outage lasting several minutes. A solutions architect must adjust the deployment process to support a canary release.

Which solution will meet these requirements?

Options:

Questions # 12:

A media storage application uploads user photos to Amazon S3 for processing by AWS Lambda functions. Application state is stored in Amazon DynamoOB tables. Users are reporting that some uploaded photos are not being processed properly. The application developers trace the logs and find that Lambda is experiencing photo processing issues when thousands of users upload photos simultaneously. The issues are the result of Lambda concurrency limits and the performance of DynamoDB when data is saved.

Which combination of actions should a solutions architect take to increase the performance and reliability of the application? (Select TWO.)

Options:

Evaluate and adjust the RCUs for the DynamoDB tables.

Evaluate and adjust the WCUs for the DynamoDB tables.

Questions # 13:

A software company hosts an application on AWS with resources in multiple AWS accounts and Regions. The application runs on a group of Amazon EC2 instances in an application VPC located in the us-east-1 Region with an IPv4 CIDR block of 10.10.0.0/16. In a different AWS account, a shared services VPC is located in the us-east-2 Region with an IPv4 CIDR block of 10.10.10.0/24. When a cloud engineer uses AWS CloudFormation to attempt to peer the application

VPC with the shared services VPC, an error message indicates a peering failure.

Which factors could cause this error? (Choose two.)

Options:

The IPv4 CIDR ranges of the two VPCs overlap

The VPCs are not in the same Region

One or both accounts do not have access to an Internet gateway

One of the VPCs was not shared through AWS Resource Access Manager

Questions # 14:

A company is building a software-as-a-service (SaaS) solution on AWS. The company has deployed an Amazon API Gateway REST API with AWS Lambda integration in multiple AWS Regions and in the same production account.

The company offers tiered pricing that gives customers the ability to pay for the capacity to make a certain number of API calls per second. The premium tier offers up to 3,000 calls per second, and customers are identified by a unique API key. Several premium tier customers in various Regions report that they receive error responses of 429 Too Many Requests from multiple API methods during peak usage hours. Logs indicate that the Lambda function is never invoked.

What could be the cause of the error messages for these customers?

Options:

The Lambda function reached its concurrency limit.

The Lambda function its Region limit for concurrency.

The company reached its API Gateway account limit for calls per second.

The company reached its API Gateway default per-method limit for calls per second.

Questions # 15:

Which combination of steps will meet these requirements? (Select THREE.)

Options:

In Amazon CloudWatch, graph the sum of the ReadThrottleEvents metric and the sum of the WriteThrottleEvents metric for each table over a period of 1 month.

In Amazon CloudWatch, graph the sum of the ConsumedReadCapacityUnits metric and the sum of the ConsumedWriteCapacityUnits metric for each table over a period of 1 month.

Change the provisioned RCUs to 1 for the unused tables. Change the provisioned WCUs to 1 for the unused tables.

Change the capacity mode of the unused tables to on-demand mode.
