Question 1

A company's website is hosted on an Amazon EC2 instance. The website's content is stored on an Amazon EBS volume. The company wants a cost-effective and automated backup solution. Which AWS service should be used?

Amazon S3 replication Amazon EC2 AMI Create Amazon EBS volumes Create Amazon EBS snapshots

Correct Answer: Create Amazon EBS snapshots

Amazon EBS snapshots are the best solution for cost-effective and automated backups of EBS volumes. EBS snapshots are incremental backups of your EBS volume, which store only the changes since your last snapshot. This makes them cost-effective and fast to create.

Question 2

Your company hosts their application on multiple EC2 instances behind a load balancer. In case of a region-wide disaster, they want to recover in another AWS region with minimal downtime. What should be the recovery strategy?

Multi-region replication Backup and restore Pilot light architecture Active-Active architecture

Correct Answer: Pilot light architecture

Pilot light architecture includes keeping a minimal version of the environment always running in the standby region. In case of disaster, the pilot light can be scaled up quickly to meet the production workload, reducing downtime significantly.

Question 3

A financial company stores their transactional data in an Amazon RDS instance. They need to ensure minimal data loss in case of a disaster. What should the company do?

Enable RDS Read Replicas Enable Multi-AZ deployment and configure automated backups Replicate data to Amazon S3 Enable Multi-AZ deployment and copy RDS snapshots

Correct Answer: Enable Multi-AZ deployment and configure automated backups

By enabling Multi-AZ deployment and configuring automated backups, the company can achieve the highest level of durability and minimize data loss. Multi-AZ configurations provide a standby replica of the primary DB instance in a different availability zone, and automated backups create point-in-time snapshots of the instance.
