Question # 73

A healthcare provider is planning to store patient data on AWS as PDF files. To comply with regulations, the company must encrypt the data and store the files in multiple locations. The data must be available for immediate access from any environment.

A.

Store the files in an Amazon S3 bucket. Use the Standard storage class. Enable server-side encryption with Amazon S3 managed keys (SSE-S3) on the bucket. Configure cross-Region replication on the bucket.

B.

Store the files in an Amazon Elastic File System (Amazon EFS) volume. Use an AWS KMS managed key to encrypt the EFS volume. Use AWS DataSync to replicate the EFS volume to a second AWS Region.

C.

Store the files in an Amazon Elastic Block Store (Amazon EBS) volume. Configure AWS Backup to back up the volume on a regular schedule. Use an AWS KMS key to encrypt the backups.

D.

Store the files in an Amazon S3 bucket. Use the S3 Glacier Flexible Retrieval storage class. Ensure that all PDF files are encrypted by using client-side encryption before the files are uploaded. Configure cross-Region replication on the bucket.

Question # 75

Question:

A company wants to deploy an internal web application on AWS. The web application must be accessible only from the company's office. The company needs to download security patches for the web application from the internet. The company has created a VPC and has configured an AWS Site-to-Site VPN connection to the company's office. A solutions architect must design a secure architecture for the web application. Which solution will meet these requirements?

Options:

A.

Deploy the web application on Amazon EC2 instances in public subnets behind a public Application Load Balancer (ALB). Attach an internet gateway to the VPC. Set the inbound source of the ALB's security group to 0.0.0.0/0.

B.

Deploy the web application on Amazon EC2 instances in private subnets behind an internal Application Load Balancer (ALB). Deploy NAT gateways in public subnets. Attach an internet gateway to the VPC. Set the inbound source of the ALB's security group to the company's office network CIDR block.

C.

Deploy the web application on Amazon EC2 instances in public subnets behind an internal Application Load Balancer (ALB). Deploy NAT gateways in private subnets. Attach an internet gateway to the VPC. Set the outbound destination of the ALB's security group to the company's office network CIDR block.

D.

Deploy the web application on Amazon EC2 instances in private subnets behind a public Application Load Balancer (ALB). Attach an internet gateway to the VPC. Set the outbound destination of the ALB's security group to 0.0.0.0/0.

Question # 76

A company runs a stateless web application in production on a group of Amazon EC2 On-Demand Instances behind an Application Load Balancer. The application experiences heavy usage during an 8-hour period each business day. Application usage is moderate and steady overnight Application usage is low during weekends.

The company wants to minimize its EC2 costs without affecting the availability of the application.

Which solution will meet these requirements?

A.

Use Spot Instances for the entire workload.

B.

Use Reserved instances for the baseline level of usage Use Spot Instances for any additional capacity that the application needs.

C.

Use On-Demand Instances for the baseline level of usage. Use Spot Instances for any additional capacity that the application needs

D.

Use Dedicated Instances for the baseline level of usage. Use On-Demand Instances for any additional capacity that the application needs

Question # 77

Question:

A company wants to migrate an application to AWS. The application runs on Docker containers behind an Application Load Balancer (ALB). The application stores data in a PostgreSQL database. The cloud-based solution must use AWS WAF to inspect all application traffic. The application experiences most traffic on weekdays. There is significantly less traffic on weekends. Which solution will meet these requirements in the MOST cost-effective way?

Options:

A.

Use a Network Load Balancer (NLB). Create a web access control list (web ACL) in AWS WAF that includes the necessary rules. Attach the web ACL to the NLB. Run the application on Amazon Elastic Container Service (Amazon ECS). Use Amazon RDS for PostgreSQL as the database.

B.

Create a web access control list (web ACL) in AWS WAF that includes the necessary rules. Attach the web ACL to the ALB. Run the application on Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon RDS for PostgreSQL as the database.

C.

Create a web access control list (web ACL) in AWS WAF that includes the necessary rules. Attach the web ACL to the ALB. Run the application on Amazon Elastic Container Service (Amazon ECS). Use Amazon Aurora Serverless as the database.

D.

Use a Network Load Balancer (NLB). Create a web access control list (web ACL) in AWS WAF that has the necessary rules. Attach the web ACL to the NLB. Run the application on Amazon Elastic Container Service (Amazon ECS). Use Amazon Aurora Serverless as the database.
