  1. 1A Solutions Architect is designing a service that must have four Amazon EC2 instances running between 8 AM and 6 PM daily. The service requires one EC2 instance outside of those hours.
    What is the MOST cost-effective way to provide enough compute?
    1. AUse one Amazon EC2 Reserved Instance and use an Auto Scaling Group scheduled action to add three EC2 On-Demand instances at 7:30 AM and remove three instances at 6:10 PM.
    2. BUse one Amazon EC2 Reserved Instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
    3. CUse one Amazon EC2 On-Demand instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
    4. DUse one Amazon EC2 On-Demand instance and use an Auto Scaling Group scheduled action to add three EC2 Spot instances at 7:30 AM and remove three instances at 6:10 PM.
  2. 2A company plans to use an Amazon VPC to deploy a web application consisting of an elastic load balancer, a fleet of web and application servers, and an
    Amazon RDS MySQL database that should not be accessible from the Internet. The proposed design must be highly available and distributed over two Availability
    Zones.
    What would be the MOST appropriate VPC design for this specific use case?
    1. ATwo public subnets for the elastic load balancer, two public subnets for the web servers, and two public subnets for Amazon RDS.
    2. BOne public subnet for the elastic load balancer, two private subnets for the web servers, and two private subnets for Amazon RDS
    3. COne public subnet for the elastic load balancer, one public subnet for the web servers, and one private subnet for the database.
    4. DTwo public subnets for the elastic load balancer, two private subnets for the web servers, and two private subnets for RDS.
  3. 3A workload in an Amazon VPC consists of a single web server launched from a custom AMI. Session state is stored in a database.
    How should the Solutions Architect modify this workload to be both highly available and scalable?
    1. ACreate a launch configuration with a desired capacity of two web servers across multiple Availability Zones. Create an Auto Scaling group with the AMI ID of the web server image. Use Amazon Route 53 latency-based routing to balance traffic across the Auto Scaling group.
    2. BCreate a launch configuration with the AMI ID of the web server image. Create an Auto Scaling group using the newly-created launch configuration, and a desired capacity of two web servers across multiple regions. Use an Application Load Balancer (ALB) to balance traffic across the Auto Scaling group.
    3. CCreate a launch configuration with the AMI ID of the web server image. Create an Auto Scaling group using the newly-created launch configuration, and a desired capacity of two web servers across multiple Availability Zones. Use an ALB to balance traffic across the Auto Scaling group.
    4. DCreate a launch configuration with the AMI ID of the web server image. Create an Auto Scaling group using the newly-created launch configuration, and a desired capacity of two web servers across multiple Availability Zones. Use Amazon Route 53 weighted routing to balance traffic across the Auto Scaling group.
