A company runs its two-tier ecommerce website on AWS. The web tier consists of a load balancer that sends traffic to Amazon EC2 instances. The database tier uses an Amazon RDS DB instance. The EC2 instances and the RDS DB instance should not be exposed to the public internet. The EC2 instances require internet access to complete payment processing of orders through a third-party web service. The application must be highly available.
Which combination of configuration options will meet these requirements? (Choose two.)

1. A. Use an Auto Scaling group to launch the EC2 instances in private subnet
2. B. Deploy an RDS Multi-AZ DB instance in private subnets.
3. C. Configure a VPC with two private subnets and two NAT gateways across two Availability Zones.Deploy an Application Load Balancer in the private subnets.
4. D. Use an Auto Scaling group to launch the EC2 instances in public subnets across two Availability Zones.Deploy an RDS Multi-AZ DB instance in private subnets.
5. E. Configure a VPC with one public subnet, one private subnet, and two NAT gateways across two Availability Zone
6. F. Deploy an Application Load Balancer in the public subnet.
7. G. Configure a VPC with two public subnets, two private subnets, and two NAT gateways across two Availability Zone
8. H. Deploy an Application Load Balancer in the public subnets.

Correct Answer: AE
Before you begin: Decide which two Availability Zones you will use for your EC2 instances. Configure your virtual private cloud (VPC) with at least one public subnet in each of these Availability Zones. These public subnets are used to configure the load balancer. You can launch your EC2 instances in other subnets of these Availability Zones instead.

A company runs an Oracle database on premises. As part of the company’s migration to AWS, the company wants to upgrade the database to the most recent available version. The company also wants to set up disaster recovery (DR) for the database. The company needs to minimize the operational overhead for normal operations and DR setup. The company also needs to maintain access to the database's underlying operating system.
Which solution will meet these requirements?

1. A. Migrate the Oracle database to an Amazon EC2 instanc
2. B. Set up database replication to a different AWS Region.
3. C. Migrate the Oracle database to Amazon RDS for Oracl
4. D. Activate Cross-Region automated backups to replicate the snapshots to another AWS Region.
5. E. Migrate the Oracle database to Amazon RDS Custom for Oracl
6. F. Create a read replica for the database in another AWS Region.
7. G. Migrate the Oracle database to Amazon RDS for Oracl
8. H. Create a standby database in another Availability Zone.

A company collects data from thousands of remote devices by using a RESTful web services application that runs on an Amazon EC2 instance. The EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket. The number of remote devices will increase into the millions soon. The company needs a highly scalable solution that minimizes operational overhead.
Which combination of steps should a solutions architect take to meet these requirements9 (Select TWO.)

1. A. Use AWS Glue to process the raw data in Amazon S3.
2. B. Use Amazon Route 53 to route traffic to different EC2 instances.
3. C. Add more EC2 instances to accommodate the increasing amount of incoming data.
4. D. Send the raw data to Amazon Simple Queue Service (Amazon SOS). Use EC2 instances to process the data.
5. E. Use Amazon API Gateway to send the raw data to an Amazon Kinesis data strea
6. F. Configure Amazon Kinesis Data Firehose to use the data stream as a source to deliver the data to Amazon S3.

Correct Answer: AE
"RESTful web services" => API Gateway.
"EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket"
=> GLUE with (Extract - Transform - Load)

A company is using a centralized AWS account to store log data in various Amazon S3 buckets. A solutions architect needs to ensure that the data is encrypted at rest before the data is uploaded to the S3 buckets. The data also must be encrypted in transit.
Which solution meets these requirements?

1. A. Use client-side encryption to encrypt the data that is being uploaded to the S3 buckets.
2. B. Use server-side encryption to encrypt the data that is being uploaded to the S3 buckets.
3. C. Create bucket policies that require the use of server-side encryption with S3 managed encryption keys (SSE-S3) for S3 uploads.
4. D. Enable the security option to encrypt the S3 buckets through the use of a default AWS Key Management Service (AWS KMS) key.

Correct Answer: A

A solutions architect is designing a new API using Amazon API Gateway that will receive requests from users. The volume of requests is highly variable; several hours can pass without receiving a single request. The data processing will take place asynchronously, but should be completed within a few seconds after a request is made.
Which compute service should the solutions architect have the API invoke to deliver the requirements at the lowest cost?

1. A. An AWS Glue job
2. B. An AWS Lambda function
3. C. A containerized service hosted in Amazon Elastic Kubernetes Service (Amazon EKS)
4. D. A containerized service hosted in Amazon ECS with Amazon EC2

Correct Answer: B
API Gateway + Lambda is the perfect solution for modern applications with serverless architecture.
