Your SAP stack has an app server at 99.5% and a HANA DB across AZs at 99.99%. A colleague says the composite SLA is 99.5% (the weakest link). Why is that wrong, and which way does the real number move?

The business signed for 99.95% S/4HANA uptime. Your AWS infrastructure SLAs all clear that bar. Why can you still breach the business-uptime SLA, and what closes the gap?

Name the four single-region HA/DR patterns for SAP and the one property that separates the 99.5% pair from the 99.99% / ~0-RPO pair.

If a single AWS transit center inside a region fails, do instances in one AZ lose connectivity to another AZ? Why or why not, and what does the answer let you trust?

An auditor asks who is accountable when S/4HANA is unavailable: AWS's service SLA or the MSP's SLA. How do the two differ in scope, and which one covers a misconfiguration outage?

You have a tightly integrated SAP system group (ERP, BW, CRM, SRM, GTS). Every per-system RPO is met on failover, yet finance reports cross-system data is inconsistent. Which objective did you miss, and what does it demand?
