   A company runs a web application on EC2 instances behind an Application Load Balancer. The application is stateless and uses an Auto Scaling group. The company has a strict Service Level Agreement (SLA) that requires 99.99% availability. The application experiences sudden, unpredictable spikes in traffic. The current Auto Scaling policy is based on average CPU utilization. During a recent spike, the application became overloaded because the scaling policy did not add instances quickly enough. What should a solutions architect do to improve the application's ability to handle sudden spikes?

   • AUse a combination of a target tracking policy and a step scaling policy, and also use an Application Load Balancer (ALB) connection draining to handle in-flight requests.
   • BUse a scheduled scaling policy to add capacity during known peak hours.
   • CUse a step scaling policy with a larger number of instances to add and a shorter cooldown period.
   • DUse a target tracking policy based on a lower CPU utilization threshold to add capacity earlier.

   A company runs a microservices application on Amazon ECS. The application has been experiencing intermittent failures that are difficult to trace. The operations team wants to identify the root cause of errors by analyzing traces across multiple services. What should a solutions architect do?

   • AEnable AWS X-Ray tracing on the ECS tasks and instrument the application code with the X-Ray SDK.
   • BEnable VPC Flow Logs and analyze them in Amazon CloudWatch Logs Insights.
   • CConfigure Amazon CloudWatch Container Insights to monitor CPU and memory usage of each task.
   • DSet up an Amazon EventBridge rule to capture all ECS task state changes and send them to Amazon SNS.

   What is the primary purpose of implementing fault isolation in a distributed system?

   • ATo eliminate the need for backups by making systems more resilient
   • BTo ensure that all components share the same failure domain for easier troubleshooting
   • CTo increase the complexity of the system to deter potential attackers
   • DTo reduce the blast radius of a failure by limiting its impact to a small set of components

   A company runs a critical relational database on a single Amazon RDS DB instance in us-east-1. The application is read-heavy, and the company has a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. The database currently has automated backups enabled. What should a solutions architect do to meet these objectives?

   • AIncrease the backup retention period to 35 days and perform a manual snapshot daily.
   • BEnable deletion protection on the database and configure a maintenance window during off-peak hours.
   • CEnable Multi-AZ deployment and create a read replica in a different AWS Region.
   • DMove the database to a larger instance class to handle more read traffic and reduce latency.
