A company is designing a VPC for a web application that will scale horizontally. They need to ensure that the IP addressing scheme can accommodate future growth without redesign. Which approach should they use?

Use a large CIDR block (e.g., /16) and divide it into smaller subnets for each tier

Use multiple VPCs with peering for each tier

Use a small CIDR block (e.g., /28) and rely on NAT for scaling

Use a single subnet for all resources

A company is deploying a multi-tier application across two Availability Zones. They need to ensure that if one AZ fails, the application remains available. Which placement strategy should they use?

Place web servers in one AZ and database servers in another AZ

Place all resources in one Availability Zone and use a Network Load Balancer

Place identical resources in both Availability Zones and use an Application Load Balancer to distribute traffic

Place resources in a single VPC with a single subnet

A company is designing a VPC for a web application that must scale. They want to avoid manual intervention when traffic increases. Which configuration supports this?

Use a NAT gateway in a single Availability Zone

Use a VPC peering connection to another VPC

Use an Auto Scaling group with a target tracking policy and distribute instances across multiple Availability Zones

Use a single large instance with an Elastic IP

An application load balancer is configured with a target group that has instances with varying processing capacities. The company wants to distribute requests based on the number of outstanding requests each instance has, so that instances with fewer pending requests receive more traffic. Which load balancing algorithm should be used?
