What is the most cost-effective solution to reduce cost without impacting performance for an AWS database using EC2 and EBS?

Single Choice

A company is running a custom database in the AWS Cloud. The database uses Amazon EC2 for compute and uses Amazon Elastic Block Store (Amazon EBS) for storage. The database runs on the latest generation of EC2 instances and uses a General Purpose SSD (gp2) EBS volume for data.

The current data volume has the following characteristics:

• The volume is 512 GB in size.
• The volume never goes above 256 GB utilization.
• The volume consistently uses around 1,500 IOPS.

A solutions architect needs to conduct an analysis of the current database storage layer and make a recommendation about ways to reduce cost.

Which solution will provide the MOST cost savings without impacting the performance of the database?

Convert the data volume to the Cloud HDD (sc1) type. Leave the volume as 512 GB. Set the volume IOPS to 1,500.

Convert the data volume to the Provisioned IOPS SSD (io2) type. Resize the volume to 256 GB. Set the volume IOPS to 1,500.

Convert the data volume to the Provisioned IOPS SSD (io2) Block Express type. Leave the volume as 512 GB. Set the volume IOPS to 1,500.

Convert the data volume to the General Purpose SSD (gp3) type. Resize the volume to 256 GB. Set the volume IOPS to 1,500.

What Backup Strategy Meets a 1-Hour RTO for Amazon EFS with Minimal Cost?

Single Choice

A company is running a distributed application on a set of Amazon EC2 instances in an Auto Scaling group. The application stores large amounts of data on an Amazon Elastic File System (Amazon EFS) file system, and new data is generated monthly. The company needs to back up the data in a secondary AWS Region to restore from in case of a performance problem in its primary Region. The company has an RTO of 1 hour. A solutions architect needs to create a backup strategy while minimizing the extra cost.

Which backup strategy should the solutions architect recommend to meet these requirements?

Create a pipeline in AWS Data Pipeline. Copy the data to an EFS file system in the secondary Region. Create a lifecycle policy to move files to the EFS One Zone-Infrequent Access storage class.

Set up automatic backups by using AWS Backup. Create a copy rule to copy backups to an Amazon S3 bucket in the secondary Region. Create a lifecycle policy to move backups to the S3 Glacier storage class.

Set up AWS DataSync and continuously copy the files to an Amazon S3 bucket in the secondary Region. Create a lifecycle policy to move files to the S3 Glacier Deep Archive storage class.

Turn on EFS Cross-Region Replication and set the secondary Region as the target. Create a lifecycle policy to move files to the EFS Infrequent Access storage class in the secondary Region.

How can the company remediate the potential single point of failure for access to the application?

Single Choice

A company is running a line-of-business (LOB) application on AWS to support its users. The application runs in one VPC, with a backup copy in a second VPC in a different AWS Region for disaster recovery. The company has a single AWS Direct Connect connection between its on-premises network and AWS. The connection terminates at a Direct Connect gateway.

All access to the application must originate from the company s on-premises network and traffic must be encrypted in transit through the use of IPsec. The company is routing traffic through a VPN tunnel over the Direct Connect connection to provide the required encryption.

A business continuity audit determines that the Direct Connect connection represents a potential single point of failure for access to the application. The company needs to remediate this issue as quickly as possible.

Which approach will meet these requirements?

Order a second Direct Connect connection to a different Direct Connect location. Terminate the second Direct Connect connection at the same Direct Connect gateway.

Configure an AWS Site-to-Site VPN connection over the internet. Terminate the VPN connection at a virtual private gateway in the secondary Region.

Create a transit gateway. Attach the VPCs to the transit gateway, and connect the transit gateway to the Direct Connect gateway. Configure an AWS Site-to-Site VPN connection, and terminate it at the transit gateway.

How can a solutions architect secure access to a new REST API in AWS without exposing it to the public internet?

Single Choice

A company is running an application in the AWS Cloud. The application consists of microservices that run on a fleet of Amazon EC2 instances in multiple Availability Zones behind an Application Load Balancer. The company recently added a new REST API that was implemented in Amazon API Gateway. Some of the older microservices that run on EC2 instances need to call this new API.

The company does not want the API to be accessible from the public internet and does not want proprietary data to traverse the public internet.

What should a solutions architect do to meet these requirements?

Create an AWS Site-to-Site VPN connection between the VPC and the API Gateway. Use API Gateway to generate a unique API key for each microservice. Configure the API methods to require the key.

Create an interface VPC endpoint for API Gateway, and set an endpoint policy to only allow access to the specific API. Add a resource policy to API Gateway to only allow access from the VPC endpoint. Change the API Gateway endpoint type to private.

Modify the API Gateway to use IAM authentication Update the IAM policy for the IAM role that is assigned to the EC2 instances to allow access to the API Gateway Move the API Gateway into a new VPC. Deploy a transit gateway and connect the VPCs.

Create an accelerator in AWS Global Accelerator, and connect the accelerator to the API Gateway. Update the route table for all VPC subnets with a route to the created Global Accelerator endpoint IP address. Add an API key for each service to use for authentication.

How Can Email Replication Backlog in AWS Regions Be Reduced?

Multiple Choice

A company is running an email application across multiple AWS Regions. The company uses Ohio (us-east-2) as the primary Region and Northern Virginia (us-east-1) as the Disaster Recovery (DR) Region. The data is continuously replicated from the primary Region to the DR Region by a single instance on the public subnet in both Regions. The replication messages between the Regions have a significant backlog during certain times of the day. The backlog clears on its own after a short time, but it affects the application s RPO.

Which of the following solutions should help remediate this performance problem? (Choose two.)

Increase the size of the instances.

Have the instance in the primary Region write the data to an Amazon SQS queue in the primary Region instead, and have the instance in the DR Region poll from this queue.

Use multiple instances on the primary and DR Regions to send and receive the replication data.

Change the DR Region to Oregon (us-west-2) instead of the current DR Region.

Attach an additional elastic network interface to each of the instances in both Regions and set up load balancing between the network interfaces.
