   A DevOps engineer wants to configure an Auto Scaling policy that maintains EC2 instance CPU utilization at approximately 50%. The policy should automatically adjust capacity to meet this target without requiring manual thresholds. Which type of scaling policy should be used?

   • AStep scaling policy
   • BTarget tracking policy
   • CSimple scaling policy
   • DScheduled scaling policy

   A company runs a batch processing application on EC2 instances. The workload is predictable: it peaks at 80% CPU for 2 hours every night, but is otherwise idle. The team wants to automate scaling to match this pattern and minimize costs. Which scaling approach is most appropriate?

   • AUse scheduled scaling actions to add capacity before the peak and remove it after
   • BUse a target tracking policy based on CPU utilization
   • CManually adjust the desired capacity each night
   • DUse a step scaling policy with a large scale-out adjustment

   A team uses AWS Lambda to process events from an Amazon SQS queue. The Lambda function is CPU-intensive and can only process a limited number of messages concurrently. During peak load, the function is invoked too frequently, causing errors and timeouts. The team wants to control the maximum number of concurrent invocations to protect downstream resources. What should they configure?

   • ASet the function timeout to a higher value
   • BSet a reserved concurrency limit on the Lambda function
   • CUse a provisioned concurrency configuration
   • DIncrease the batch size for the SQS event source

   A DevOps engineer notices that an Auto Scaling group is repeatedly adding and removing instances in short succession, causing instability and increased costs. This behavior is known as scaling thrashing. Which remediation strategy is MOST effective to reduce this issue?

   • ASet the Auto Scaling group's minimum and maximum size to the same value
   • BDecrease the cooldown period to allow faster reactions
   • CUse a simple scaling policy with a small adjustment step
   • DIncrease the cooldown period and use a larger scaling adjustment step

   A team is designing a multi-Region architecture for disaster recovery. They want to ensure that if one Region fails, traffic is automatically redirected to a healthy Region. Which Route 53 routing policy is BEST suited for this requirement?

   • AGeolocation routing policy
   • BWeighted routing policy
   • CLatency-based routing policy
   • DFailover routing policy
