A company runs an ecommerce application on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2

Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales based on CPU utilization metrics. The ecommerce

application stores the transaction data in a MySQL 8.0 database that is hosted on a large EC2 instance.

The database's performance degrades quickly as application load increases. The application handles more read requests than write transactions.

The company wants a solution that will automatically scale the database to meet the demand of unpredictable read workloads while maintaining

high availability.

Which solution will meet these requirements?

• A. Use Amazon Redshift with a single node for leader and compute functionality.

• B. Use Amazon RDS with a Single-AZ deployment Configure Amazon RDS to add reader instances in a different Availability Zone.

• C. Use Amazon Aurora with a Multi-AZ deployment. Configure Aurora Auto Scaling with Aurora Replicas.

• D. Use Amazon ElastiCache for Memcached with EC2 Spot Instances.

A solutions architect is designing a VPC with public and private subnets. The VPC and subnets use IPv4 CIDR blocks. There is one public subnet

and one private subnet in each of three Availability Zones (AZs) for high availability. An internet gateway is used to provide internet access for the

public subnets. The private subnets require access to the internet to allow Amazon EC2 instances to download software updates.

What should the solutions architect do to enable Internet access for the private subnets?

• A. Create three NAT gateways, one for each public subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to

  the NAT gateway in its AZ.

• B. Create three NAT instances, one for each private subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic

  to the NAT instance in its AZ.

• C. Create a second internet gateway on one of the private subnets. Update the route table for the private subnets that forward non-VPC traffic

  to the private internet gateway.

• D. Create an egress-only internet gateway on one of the public subnets. Update the route table for the private subnets that forward non-VPC

  traffic to the egress-only Internet gateway.

A company recently migrated a message processing system to AWS. The system receives messages into an ActiveMQ queue running on an

Amazon EC2 instance. Messages are processed by a consumer application running on Amazon EC2. The consumer application processes the

messages and writes results to a MySQL database running on Amazon EC2. The company wants this application to be highly available with low

operational complexity.

Which architecture offers the HIGHEST availability?

• A. Add a second ActiveMQ server to another Availability Zone. Add an additional consumer EC2 instance in another Availability Zone.

  Replicate the MySQL database to another Availability Zone.

• B. Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an additional consumer EC2 instance in

  another Availability Zone. Replicate the MySQL database to another Availability Zone.

• C. Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an additional consumer EC2 instance in

  another Availability Zone. Use Amazon RDS for MySQL with Multi-AZ enabled.

• D. Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an Auto Scaling group for the consumer EC2

  instances across two Availability Zones. Use Amazon RDS for MySQL with Multi-AZ enabled.

A company runs an on-premises application that is powered by a MySQL database. The company is migrating the application to AWS to increase

the application's elasticity and availability.

The current architecture shows heavy read activity on the database during times of normal operation. Every 4 hours, the company's development

team pulls a full export of the production database to populate a database in the staging environment. During this period, users experience

unacceptable application latency. The development team is unable to use the staging environment until the procedure completes.

A solutions architect must recommend replacement architecture that alleviates the application latency issue. The replacement architecture also

must give the development team the ability to continue using the staging environment without delay.

Which solution meets these requirements?

• A. Use Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production. Populate the staging database by implementing a backup and

  restore process that uses the mysqldump utility.

• B. Use Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production. Use database cloning to create the staging database on-demand.

• C. Use Amazon RDS for MySQL with a Multi-AZ deployment and read replicas for production. Use the standby instance for the staging

  database.

• D. Use Amazon RDS for MySQL with a Multi-AZ deployment and read replicas for production. Populate the staging database by implementing

  a backup and restore process that uses the mysqldump utility.
