1. A. Create an Auto Scaling group that uses three instances across each of two Regions
2. B. Modify the Auto Scaling group to use three instances across each of two Availability Zones
3. C. Create an Auto Scaling template that can be used to quickly create more instances in another Region
4. D. Change the ALB in front of the Amazon EC2 instances in a round-robin configuration to balance traffic to the web tier

A company has deployed an API in a VPC behind an internet-facing Application Load Balancer (ALB) An application that consumes the API as a client is deployed in a second account in private subnets behind a NAT gateway. When requests to the client application increase, the NAT gateway costs are higher than expected. A solutions architect has configured the ALB to be internal.
Which combination of architectural changes will reduce the NAT gateway costs'? (Select TWO )

1. A. Configure a VPC peering connection between the two VPC
2. B. Access the API using the private address
3. C. Configure an AWS Direct Connect connection between the two VPC
4. D. Access the API using the private address.
5. E. Configure a ClassicLink connection for the API into the client VPC Access the API using the ClassicLink address.
6. F. Configure a PrivateLink connection for the API into the client VP
7. G. Access the API using the PrivateLink address.
8. H. Configure an AWS Resource Access Manager connection between the two accounts Access the API using the private address

A solutions architect is designing a solution where users will De directed to a backup static error page it the primary website is unavailable The primary website's DNS records are hosted in Amazon Route 53 where their domain is pointing to an Application Load Balancer (ALB)
Which configuration should the solutions architect use to meet the company's needs while minimizing changes and infrastructure overhead?

1. A. Point a Route 53 alias record to an Amazon CloudFront distribution with the ALB as one of its origins Then, create custom error pages for the distribution
2. B. Set up a Route 53 active-passive failover configuration Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy
3. C. Update the Route 53 record to use a latency-based routing policy Add the backup static error page hosted within an Amazon S3 bucket to the record so the traffic is sent to the most responsive endpoints
4. D. Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoints Route 53 will only send requests to the instance if the health checks fail for the ALB

Correct Answer: B

An application running on AWS uses an Amazon Aurora Multi-AZ deployment for its database When evaluating performance metrics, a solutions architect discovered that the database reads are causing high I/O and adding latency to the write requests against the database
What should the solutions architect do to separate the read requests from the write requests?

1. A. Enable read-through caching on the Amazon Aurora database
2. B. Update the application to read from the Multi-AZ standby instance
3. C. Create a read replica and modify the application to use the appropriate endpoint
4. D. Create a second Amazon Aurora database and link it to the primary database as a read replica.

Correct Answer: C
