Question # 81

A company is developing a web application that runs on Amazon EC2 instances in an Auto Scaling group behind a public-facing Application Load Balancer (ALB). Only users from a specific country are allowed to access the application. The company needs the ability to log the access requests that have been blocked. The solution should require the least possible maintenance.

Which solution meets these requirements?

A.

Create an IPSet containing a list of IP ranges that belong to the specified country. Create an AWS WAF web ACL. Configure a rule to block any requests that do not originate from an IP range in theIPSet. Associate the rule with the web ACL. Associate the web ACL with the ALB.

B.

Create an AWS WAF web ACL. Configure a rule to block any requests that do not originate from the specified country. Associate the rule with the web ACL. Associate the web ACL with the ALB.

C.

Configure AWS Shield to block any requests that do not originate from the specified country. Associate AWS Shield with the ALB.

D.

Create a security group rule that allows ports 80 and 443 from IP ranges that belong to the specified country. Associate the security group with the ALB.

Question # 83

A company ingests and processes streaming market data. The data rate is constant. A nightly process that calculates aggregate statistics is run, and each execution takes about 4 hours to complete. The statistical analysis is not mission critical to the business, and previous data points are picked up on the next execution if a particular run fails.

The current architecture uses a pool of Amazon EC2 Reserved Instances with 1-year reservations running full time to ingest and store the streaming data in attached Amazon EBS volumes. On-Demand EC2 instances are launched each night to perform the nightly processing, accessing the stored data from NFS shares on the ingestion servers, and terminating the nightly processing servers when complete. The Reserved Instance reservations are expiring, and the company needs to determine whether to purchase new reservations or implement a new design.

Which is the most cost-effective design?

A.

Update the ingestion process to use Amazon Kinesis Data Firehose to save data to Amazon S3. Use a scheduled script to launch a fleet of EC2 On-Demand Instances each night to perform the batch processing of the S3 data. Configure the script to terminate the instances when the processing is complete.

B.

Update the ingestion process to use Amazon Kinesis Data Firehose to save data to Amazon S3. Use AWS Batch with Spot Instances to perform nightlyprocessing with a maximum Spot price that is 50% of the On-Demand price.

C.

Update the ingestion process to use a fleet of EC2 Reserved Instances with 3-year reservations behind a Network Load Balancer. Use AWS Batch with SpotInstances to perform nightly processing with a maximum Spot price that is 50% of the On-Demand price.

D.

Update the ingestion process to use Amazon Kinesis Data Firehose to save data to Amazon Redshift. Use Amazon EventBridge to schedule an AWS Lambdafunction to run nightly to query Amazon Redshift to generate the daily statistics.

Question # 84

Question:

A company provisions short-lived AWS accounts for students. Each account needs access to ml.p2.xlarge SageMaker instances for training and inference. The default quotas are insufficient.

How should quota increases be automated during account provisioning?

A.

Create a quota request template inus-east-1, enable template association, and add quotas for ml.p2.xlarge training and endpoint usage in ap-southeast-2.

B.

Use ml.p2.xlarge training warm pool quota in ap-southeast-2.

C.

Create the template in ap-southeast-2 for SageMaker quotas in us-east-1.

D.

Use warm pool quotas in us-east-1.

Question # 85

A solutions architect is creating an AWS CloudFormation template from an existing manually created non-production AWS environment The CloudFormation template can be destroyed and recreated as needed The environment contains an Amazon EC2 instance The EC2 instance has an instance profile that the EC2 instance uses to assume a role in a parent account

The solutions architect recreates the role in a CloudFormation template and uses the same role name When the CloudFormation template is launched in the child account, the EC2 instance can no longer assume the role in the parent account because of insufficient permissions

What should the solutions architect do to resolve this issue?

A.

In the parent account edit the trust policy for the role that the EC2 instance needs to assume Ensure that the target role ARN in the existing statement that allows the sts AssumeRole action is correct Save the trust policy

B.

In the parent account edit the trust policy for the role that the EC2 instance needs to assume Add a statement that allows the sts AssumeRole action for the root principal of the child account Save the trust policy

C.

Update the CloudFormation stack again Specify only the CAPABILITY_NAMED_IAM capability

D.

Update the CloudFormation stack again Specify the CAPABIUTYJAM capability and the CAPABILITY_NAMEDJAM capability

Question # 86

A solutions architect is investigating an issue in which a company cannot establish new sessions in Amazon Workspaces. An initial analysis indicates that the issue involves user profiles. The AmazonWorkspaces environment is configured to use Amazon FSx for Windows File Server as the profile share storage. The FSx for Windows File Server file system is configured with 10 TB of storage.

The solutions architect discovers that the file system has reached its maximum capacity. The solutions architect must ensure that users can regain access. The solution also must prevent the problem from occurring again.

Which solution will meet these requirements?

A.

Remove old user profiles to create space. Migrate the user profiles to an Amazon FSx for Lustre file system.

B.

Increase capacity by using the update-file-system command. Implement an Amazon CloudWatch metric that monitors free space. Use Amazon EventBridge to invoke an AWS Lambda function to increase capacity as required.

C.

Monitor the file system by using the FreeStorageCapacity metric in Amazon CloudWatch. Use AWS Step Functions to increase the capacity as required.

D.

Remove old user profiles to create space. Create an additional FSx for Windows File Server file system. Update the user profile redirection for 50% of the users to use the new file system.

Question # 87

A retail company has an on-premises data center in Europe. The company also has a multi-Region AWS presence that includes the eu-west-1 and us-east-1 Regions. The company wants to be able to route network traffic from its on-premises infrastructure into VPCs in either of those Regions. The company also needs to support traffic that is routed directly between VPCs in those Regions. No single points of failure can exist on the network.

The company already has created two 1 Gbps AWS Direct Connect connections from its on-premises data center. Each connection goes into a separate Direct Connect location in Europe for high availability. These two locations are named DX-A and DX-B, respectively. Each Region has a single AWS Transit Gateway that is configured to route all inter-VPC traffic within that Region.

Which solution will meet these requirements?

A.

Create a private VIF from the DX-A connection into a Direct Connect gateway. Create a private VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with the Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.

B.

Create a transit VIF from the DX-A connection into a Direct Connect gateway. Associate the eu-west-1 transit gateway with this Direct Connect gateway. Create a transit VIF from the DX-B connection into a separate Direct Connect gateway. Associate the us-east-1 transit gateway with this separate Direct Connect gateway. Peer the Direct Connect gateways with each other to support high availability and cross-Region routing.

C.

Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Configure the Direct Connect gateway to route traffic between the transit gateways.

D.

Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.
