Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Auto Scaling
AWS Auto Scaling can automatically adjust the number of EC2 instances based on CloudWatch alarms for CPU utilization, making it suitable for scaling SAP application servers. Option A is wrong because Elastic Load Balancing distributes traffic but does not scale instances. Option B is wrong because AWS Lambda is for serverless compute, not for running SAP application servers. Option C is wrong because AWS CloudFormation is an infrastructure-as-code service, not for automatic scaling.
