B. Convert the Aurora cluster to an Aurora global database. Configure managed failover.
C. Create a new Aurora cluster in us-west-1 that has Cross-Region Replication.
D. Create a new Aurora cluster in us-west-1. Use AWS Database Migration Service (AWS DMS) to sync both clusters.

Answer

B


Q133. A company runs workloads in the AWS Cloud. The company wants to centrally collect security data to assess security across the entire company and to improve workload protection.

C. Configure a data lake in Amazon Security Lake to collect the security data. Upload the data to an Amazon S3 bucket.
D. Configure an AWS Database Migration Service (AWS DMS) replication instance to load the security data into an Amazon RDS cluster.

Answer

C


Q134. A company is migrating five on-premises applications to VPCs in the AWS Cloud. Each application is currently deployed in isolated virtual networks on premises and should be deployed similarly in the AWS Cloud. The applications need to reach a shared services VPC. All the applications must be able to communicate with each other.

If the migration is successful, the company will repeat the migration process for more than 100 applications.

Which solution will meet these requirements with the LEAST administrative overhead?

A. Deploy software VPN tunnels between the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets to the shared services VPC.
B. Deploy VPC peering connections between the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets to the shared services VPC through the peering connection.
C. Deploy an AWS Direct Connect connection between the application VPCs and the shared services VPAdd routes from the application VPCs in their subnets to the shared services VPC and the applications VPCs. Add routes from the shared services VPC subnets to the applications VPCs.
D. Deploy a transit gateway with associations between the transit gateway and the application VPCs and the shared services VPC. Add routes between the application VPCs in their subnets and the application VPCs to the shared services VPC through the transit gateway.

Answer

D


Q135. A company wants to use Amazon Elastic Container Service (Amazon ECS) to run its on-premises application in a hybrid environment. The application currently runs on containers on premises.

The company needs a single container solution that can scale in an on-premises, hybrid, or cloud environment. The company must run new application containers in the AWS Cloud and must use a load balancer for HTTP traffic.

Which combination of actions will meet these requirements? (Choose two.)

A. Set up an ECS cluster that uses the AWS Fargate launch type for the cloud application containers. Use an Amazon ECS Anywhere external launch type for the on-premises application containers.
B. Set up an Application Load Balancer for cloud ECS services.
C. Set up a Network Load Balancer for cloud ECS services.
D. Set up an ECS cluster that uses the AWS Fargate launch type. Use Fargate for the cloud application containers and the on-premises application containers.
E. Set up an ECS cluster that uses the Amazon EC2 launch type for the cloud application containers. Use Amazon ECS Anywhere with an AWS Fargate launch type for the on-premises application containers.

Answer

A, B


Q136. A company wants to relocate its on-premises MySQL database to AWS. The database accepts regular imports from a client-facing application, which causes a high volume of write operations. The company is concerned that the amount of traffic might be causing performance issues within the application.

How should a solutions architect design the architecture on AWS?

A. Provision an Amazon RDS for MySQL DB instance with Provisioned IOPS SSD storage. Monitor write operation metrics by using Amazon CloudWatch. Adjust the provisioned IOPS if necessary.
B. Provision an Amazon RDS for MySQL DB instance with General Purpose SSD storage. Place an Amazon ElastiCache cluster in front of the DB instance. Configure the application to query ElastiCache instead.
C. Provision an Amazon DocumentDB (with MongoDB compatibility) instance with a memory optimized instance type. Monitor Amazon CloudWatch for performance-related issues. Change the instance class if necessary.
D. Provision an Amazon Elastic File System (Amazon EFS) file system in General Purpose performance mode. Monitor Amazon CloudWatch for IOPS bottlenecks. Change to Provisioned Throughput performance mode if necessary.

Answer

A


Q137. A company runs an application in the AWS Cloud that generates sensitive archival data files. The company wants to rearchitect the application’s data storage. The company wants to encrypt the data files and to ensure that third parties do not have access to the data before the data is encrypted and sent to AWS. The company has already created an Amazon S3 bucket.

Which solution will meet these requirements?

A. Configure the S3 bucket to use client-side encryption with an Amazon S3 managed encryption key. Configure the application to use the S3 bucket to store the archival files.
B. Configure the S3 bucket to use server-side encryption with AWS KMS keys (SSE-KMS). Configure the application to use the S3 bucket to store the archival files.
C. Configure the S3 bucket to use dual-layer server-side encryption with AWS KMS keys (SSE-KMS). Configure the application to use the S3 bucket to store the archival files.
D. Configure the application to use client-side encryption with a key stored in AWS Key Management Service (AWS KMS). Configure the application to store the archival files in the S3 bucket.

Answer

D


Q138. A company uses Amazon RDS with default backup settings for its database tier. The company needs to make a daily backup of the database to meet regulatory requirements. The company must retain the backups for 30 days.

Which solution will meet these requirements with the LEAST operational overhead?

A. Write an AWS Lambda function to create an RDS snapshot every day.
B. Modify the RDS database to have a retention period of 30 days for automated backups.
C. Use AWS Systems Manager Maintenance Windows to modify the RDS backup retention period.
D. Create a manual snapshot every day by using the AWS CLI. Modify the RDS backup retention period.

Answer

B


Q139. A company that runs its application on AWS uses an Amazon Aurora DB cluster as its database. During peak usage hours when multiple users access and read the data, the monitoring system shows degradation of database performance for the write queries. The company wants to increase the scalability of the application to meet peak usage demands.

Which solution will meet these requirements MOST cost-effectively?

A. Create a second Aurora DB cluster. Configure a copy job to replicate the users’ data to the new database. Update the application to use the second database to read the data.
B. Create an Amazon DynamoDB Accelerator (DAX) cluster in front of the existing Aurora DB cluster. Update the application to use the DAX cluster for read-only queries. Write data directly to the Aurora DB cluster.
C. Create an Aurora read replica in the existing Aurora DB cluster. Update the application to use the replica endpoint for read-only queries and to use the cluster endpoint for write queries.
D. Create an Amazon Redshift cluster. Copy the users’ data to the Redshift cluster. Update the application to connect to the Redshift cluster and to perform read-only queries on the Redshift cluster.

Answer

C


Q140. A company’s near-real-time streaming application is running on AWS. As the data is ingested, a job runs on the data and takes 30 minutes to complete.
