1. A company's production application runs online transaction processing (OLTP) transactions on an Amazon RDS MySQL DB instance. The company is launching a new reporting tool that will access the same data. The reporting tool must be highly available and not impact the performance of the production application.How can this be achieved?

A) Create hourly snapshots of the production RDS DB instance.
B) Create a Single-AZ RDS Read Replica of the production RDS DB instance. Create a second Single-AZ RDS Read Replica from the replica.
C) Create multiple ROS Read Replicas of the production RDS DB instance. Place the Read Replicas in an Auto Scaling group
D) Create a Multi-AZ RDS Read Replica of the production RDS DB instance.



2. A company has two-tier application architecture that runs in public and private subnets. Amazon EC2 instances running the web application are in the public subnet and a database runs on the private subnet. The web application instances and the database are running in a single Availability Zone (AZ).Which combination of steps should a solutions architect take to provide high availability for this architecture? Select two(Select 2answers)

A) Create new public and private subnets in a new AZ. Create a database using Amazon EC2 in one AZ
B) Add the existing web application instances to an Auto Scaling group behind an Application Load Balancer.
C) Create new public and private subnets in the same AZ for high availability
D) Create new public and private subnets in the same VPC, each in a new AZ. Migrate the database to an Amazon RDS multi-AZ deployment
E) Create an Amazon EC2 Auto Scaling group and Application Load Balancer spanning multiple AZS


3. A company's website runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The website has a mix of dynamic and static content. User around the globe are reporting that the website is slow.Which set of actions will improve website performance for users worldwide?

A) Create an Amazon CloudFront distribution and configure the ALB as an origin. Then update the Amazon Route 53 record to point to the CloudFront distribution.
B) Launch new EC2 instances hosting the same web application in different Regions closer to the users. Then register the instances with the same ALB using cross-Region VPC peering.
C) Create a latency-based Amazon Route 53 record for the ALB. Then launch new EC2 instances with larger instance sizes and register the instances with the ALB.
D) Host the website in an Amazon S3 bucket in the Regions closest to the users and delete the ALB and EC2 instances. Then update an Amazon Route 53 record to point to the S3 buckets.



4. A company's application is running on Amazon EC2 instance within an Auto Scaling group behind an Elastic Load Balancer. Based on the application's history, the company anticipates a spike in traffic during a holiday each year. A solutions architect must design a strategy to ensure that the Auto Scaling group proactively increases capacity to minimize any performance impact on application users.Which solution will meet these requirements?

A) Configure an Amazon Simple Notification Service (Amazon SNS) notification to send alerts when there are autoscaling EC2_INSTANCE_LAUNCH events.
B) Create a recurring scheduled action to scale up the Auto Scaling group before the expected period of peak demand.
C) Create an Amazon CloudWatch alarm to scale up the EC2 instances when CPU utilization exceeds 90%
D) Increase the minimum and maximum number of EC2 instances in the Auto Scaling group during the peak demand period.



5. An Amazon EC2 administrator created the following policy associated with an IAM group containing several users:{ 'Version': '2012-10-17', 'Statement': { { 'Effect': 'Allow', 'Action': 'ec2:TerminateInstances', 'Resource': '*', 'Condition': { 'IpAddress': { 'aws:SourceIP': '10.100.100.0/24' } } }, { 'Effect': 'Deny', 'Action': 'ec2:*', 'Resource': '*', 'Condition': { 'StringNotEquals': { 'ec2:Region': 'us-east-1' } } } }}What is the effect of this policy?

A) Users can terminate an EC2 instance in any AWS Region except us-east-1.
B) Users can terminate an EC2 instance with the IP address 10.100.100.1 in the us-east-1 Region
C) Users can terminate an EC2 instance in the us-east-1 Region when the user's source IP is 10.100.100.254
D) Users cannot terminate an EC2 instance in the us-east-1 Region when the user's source IP is 10.100.100.254
