PAS-C01 Operations and Maintenance Practice Question
An SAP system running on AWS experiences periodic performance degradation. Analysis shows that the issue occurs when an on-premises monitoring system polls the SAP application server. Which AWS service can help mitigate this by caching or throttling requests?
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 WAF
(AWS WAF) is correct because AWS WAF can rate-limit incoming requests from specific IP addresses, reducing the load caused by frequent polling from the on-premises monitoring system. Option A (Amazon Route 53) is a DNS service and cannot throttle or cache application-level requests. Option C (Amazon CloudFront) caches content but is not designed for application-level throttling of requests to an SAP application server. Option D (Elastic Load Balancing) distributes traffic but does not provide request throttling or rate limiting.
