Amazon (SAA-C03) Exam Questions And Answers page 10
A company has been storing analytics data in an Amazon RDS instance for the past few years. The company asked a solutions architect to find a solution that allows users to access this data using an API. The expectation is that the application will experience periods of inactivity but could receive bursts of traffic within seconds.
Which solution should the solutions architect suggest?
Which solution should the solutions architect suggest?
Set up an Amazon API Gateway and use AWS Elastic Beanstalk.
Set up an Amazon API Gateway and use AWS Lambda functions.
Set up an Amazon API Gateway and use Amazon EC2 with Auto Scaling.

A company has copied 1 PB of data from a colocation facility to an Amazon S3 bucket in the us-east-1 Region using an AWS Direct Connect link. The company now wants to copy the data to another S3 bucket in the us-west-2 Region. The colocation facility does not allow the use of AWS Snowball.
What should a solutions architect recommend to accomplish this?
What should a solutions architect recommend to accomplish this?
Order a Snowball Edge device to copy the data from one Region to another Region.
Transfer contents from the source S3 bucket to a target S3 bucket using the S3 console.
Use the aws S3 sync command to copy data from the source bucket to the destination bucket.
Add a cross-Region replication configuration to copy objects across S3 buckets in different Regions.

A company has created a multi-tier application for its ecommerce website. The website uses an Application Load Balancer that resides in the public subnets, a web tier in the public subnets, and a MySQL cluster hosted on Amazon EC2 instances in the private subnets. The MySQL database needs to retrieve product catalog and pricing information that is hosted on the internet by a third-party provider. A solutions architect must devices a strategy that maximizes security without increasing operational overhead.
What should the solutions architect do to meet these requirements?
What should the solutions architect do to meet these requirements?
Deploy a NAT instance in the VPC. Route all the internet-based traffic through the NAT instance.
Deploy a NAT gateway in the public subnets. Modify the private subnet route table to direct all internet-bound traffic to the NAT gateway.
Configure an internet gateway and attach it to the VPC. Modify the private subnet route table to direct internet-bound traffic to the internet gateway.
Configure a virtual private gateway and attach it to the VPC. Modify the private subnet route table to direct internet-bound traffic to the virtual private gateway.

A company has created an isolated backup of its environment in another Region. The application is running in warm standby mode and is fronted by an Application Load Balancer (ALB). The current failover process is manual and requires updating a DNS alias record to point to the secondary ALB in another Region.
What should a solutions architect do to automate the failover process?
What should a solutions architect do to automate the failover process?
Enable an ALB health check
Enable an Amazon Route 53 health check.
Crate an CNAME record on Amazon Route 53 pointing to the ALB endpoint.
Create conditional forwarding rules on Amazon Route 53 pointing to an internal BIND DNS server.

A company has created a VPC with multiple private subnets in multiple Availability Zones (AZs) and one public subnet in one of the AZs. The public subnet is used to launch a NAT gateway. There are instances in the private subnets that use a NAT gateway to connect to the internet. In case of an AZ failure, the company wants to ensure that the instances are not all experiencing internet connectivity issues and that there is a backup plan ready.
Which solution should a solutions architect recommend that is MOST highly available?
Which solution should a solutions architect recommend that is MOST highly available?
Create a new public subnet with a NAT gateway in the same AZ. Distribute the traffic between the two NAT gateways.
Create an Amazon EC2 NAT instance in a new public subnet. Distribute the traffic between the NAT gateway and the NAT instance.
Create public subnets in each AZ and launch a NAT gateway in each subnet. Configure the traffic from the private subnets in each AZ to the respective NAT gateway.
Create an Amazon EC2 NAT instance in the same public subnet. Replace the NAT gateway with the NAT instance and associate the instance with an Auto Scaling group with an appropriate scaling policy.

A company has deployed a database in Amazon RDS for MySQL. Due to increased transactions, the database support team is reporting slow reads against the DB instance and recommends adding a read replica.
Which combination of actions should a solutions architect take before implementing this change? (Choose two.)
Which combination of actions should a solutions architect take before implementing this change? (Choose two.)
Enable binlog replication on the RDS primary node.
Choose a failover priority for the source DB instance.
Allow long-running transactions to complete on the source DB instance.
Create a global table and specify the AWS Regions where the table will be available.
Enable automatic backups on the source instance by setting the backup retention period to a value other than 0.

A company has deployed a multiplayer game for mobile devices. The game requires live location tracking of players based on latitude and longitude. The data store for the game must support rapid updates and retrieval of locations.
The game uses an Amazon RDS for PostgreSQL DB instance with read replicas to store the location data. During peak usage periods, the database is unable to maintain the performance that is needed for reading and writing updates. The game s user base is increasing rapidly.
What should a solutions architect do to improve the performance of the data tier?
