What is a primary benefit of building loosely coupled systems?

It reduces the need for security controls

It eliminates the need for monitoring

A failure in one component is less likely to cause a failure in other components

A company runs a customer-facing web application on a single Amazon EC2 instance in one Availability Zone. The application experiences occasional unplanned instance failures, causing downtime. The company wants to improve availability with minimal architectural change. What should the company do?

Create an Amazon Machine Image (AMI) backup of the instance daily.

Launch a second instance in a different Availability Zone and place both behind an Application Load Balancer.

Increase the instance size to handle more load and reduce the chance of failure.

Place the instance in a different AWS Region and update the DNS record.

A company runs a development environment that is only used during business hours (9 AM to 5 PM) on weekdays. The environment consists of several EC2 instances. The company wants to reduce costs. What is the most effective way to achieve this?

Move the instances to a different AWS Region.

Purchase Reserved Instances for the environment.

Stop the instances outside of business hours.

Terminate the instances and recreate them from an AMI each morning.

How can using managed services help with cost optimization?

By reducing the operational overhead of maintaining the underlying infrastructure

By automatically reducing the price of all AWS services

By providing unlimited storage for free

By eliminating all compute costs
