Amazon Web Services Updated SAA-C03 Exam Questions and Answers by clayton

This solution meets the requirements because it allows the company to track and manage its cloud spending by using cost allocation tags to assign costs to different departments, creating usage budgets to set spending limits, and adding alert thresholds to receive notifications when the spending reaches a certain percentage of the budget. This way, the company can monitor its experimental workloads and avoid overspending on the cloud.

This solution meets the requirements because it enables the company to observe the performance and behavior of its microservices-based application on Amazon EKS. Amazon CloudWatch Container Insights is a feature that collects, aggregates, and summarizes metrics and logs from containerized applications and microservices. Container Insights integrates with Amazon EKS and Kubernetes to provide metrics at the cluster, node, pod, task, and service level. You can use Container Insights to monitor the CPU, memory, disk, and network utilization of your EKS clusters and identify bottlenecks, latency spikes, and other issues. AWS X-Ray is a service that collects data about requests that your application serves, and provides tools that you can use to view, filter, and gain insights into that data. X-Ray integrates with Amazon EKS and Kubernetes to trace the requests that your microservices make to downstream AWS resources, microservices, databases, and web APIs. You can use X-Ray to analyze the root cause of errors, faults, and performance issues, and visualize the service map of your application.

To design a resilient solution that can improve the recovery time for the system, a solutions architect should recommend creating an Amazon CloudWatch alarm to recover the EC2 instance in case of failure. This solution has the following benefits:

It allows the EC2 instance to be automatically recovered when a system status check failure occurs, such as loss of network connectivity, loss of system power, software issues on the physical host, or hardware issues on the physical host that impact network reachability1.

It preserves the instance ID, private IP addresses, Elastic IP addresses, and all instance metadata of the original instance. A recovered instance is identical to the original instance, except for any data that is in-memory, which is lost during the recovery process1.

It does not require any modification of the application code or the EC2 instance configuration. The solutions architect can create a CloudWatch alarm using the AWS Management Console, the AWS CLI, or the CloudWatch API2.

This solution meets the requirements because it uses the following components and features:

AdministratorAccess identity-based policy: This is an AWS managed policy that provides full access to AWS services and resources1. By attaching this policy to the IAM user group, the solutions architect can grant the permissions needed for the designated employees to perform any task in the AWS account.

IAM user group: This is a collection of IAM users that share common permissions2. By creating a user group and adding the five designated employees as members, the solutions architect can simplify the management of permissions and reduce the risk of human errors or inconsistencies.

IAM users: These are identities that represent the designated employees in AWS2. By creating an IAM user for each employee and requiring them to sign in with their own credentials, the solutions architect can enhance the security and accountability of the AWS account.
