SAA-C03 Exam Dumps - AWS Certified Solutions Architect - Associate (SAA-C03)

In compliance mode, a protected object version can't be overwritten or deleted by any user, including the root user in your AWS account. When an object is locked in compliance mode, its retention mode can't be changed, and its retention period can't be shortened. Compliance mode helps ensure that an object version can't be overwritten or deleted for the duration of the retention period. In governance mode, users can't overwrite or delete an object version or alter its lock settings unless they have special permissions. With governance mode, you protect objects against being deleted by most users, but you can still grant some users permission to alter the retention settings or delete the object if necessary. In Governance mode, Objects can be deleted by some users with special permissions, this is against the requirement.

Compliance:

- Object versions can't be overwritten or deleted by any user, including the root user

- Objects retention modes can't be changed, and retention periods can't be shortened

Governance:

- Most users can't overwrite or delete an object version or alter its lock settings

- Some users have special permissions to change the retention or delete the object

This solution meets the requirements of directing users to a backup static error page if the primary website is unavailable, minimizing changes and infrastructure overhead. Route 53active-passive failover configuration can route traffic to a primary resource when it is healthy or to a secondary resource when the primary resource is unhealthy. Route 53 health checks can monitor the health of the ALB endpoint and trigger the failover when needed. The static error page can be hosted in an S3 bucket that is configured as a website, which is a simple and cost-effective way to serve static content.

Option A is incorrect because using a latency routing policy can route traffic based on the lowest network latency for users, but it does not provide failover functionality. Option C is incorrect because using an active-active configuration with the ALB and an EC2 instance can increase the infrastructure overhead and complexity, and it does not guarantee that the EC2 instance will always be healthy. Option D is incorrect because using a multivalue answer routing policy can return multiple values for a query, but it does not provide failover functionality.

AWS Backup provides a centralized, fully managed solution to automate and manage backups for a wide range of AWS resources, including Aurora databases. Configuring a backup plan with daily backups and a 90-day retention policy ensures operational efficiency and simplicity for compliance purposes.

Option A:Aurora automated backups support point-in-time recovery but do not provide the operational efficiency of a centralized backup management system like AWS Backup.

Option B:AWS Backup with point-in-time recovery is a valid solution but does not specify daily backups with retention, which is the most operationally efficient approach.

Option C:Manual backups require significant operational overhead to create and delete backups regularly, which is not efficient.

Option D:Using AWS Backup with a daily backup plan and 90-day retention provides an automated and efficient solution.

Backing Up Aurora Databases

The company wants to deploy its containerized application workloads to a VPC across three Availability Zones, with high availability and minimal changes to the application. The solution that will meet these requirements with the least operational overhead is:

Use Amazon Elastic Container Service (Amazon ECS). Amazon ECS is a fully managed container orchestration service that allows you to run and scale containerized applications on AWS. Amazon ECS eliminates the need for you to install, operate, and scale your own cluster management infrastructure. Amazon ECS also integrates with other AWS services, such as VPC, ELB, CloudFormation, CloudWatch, IAM, and more.

Configure Amazon ECS Service Auto Scaling to use target tracking scaling. Amazon ECS Service Auto Scaling allows you to automatically adjust the number of tasks in your service based on the demand or custom metrics. Target tracking scaling is a policy type that adjusts the number of tasks in your service to keep a specified metric at a target value. For example, you can use target tracking scaling to maintain a target CPU utilization or request count per task for your service.

Set the minimum capacity to 3. This ensures that your service always has at least three tasks running across three Availability Zones, providing high availability and fault tolerance for your application.

Set the task placement strategy type to spread with an Availability Zone attribute. This ensures that your tasks are evenly distributed across the Availability Zones in your cluster, maximizing the availability of your service.

This solution will provide high availability across Availability Zones, require minimal changes to the application, and reduce the operational overhead of managing your own cluster infrastructure.
