QOS with Exactly Once (EO) delivery guarantee corresponds to tRFC (transactional RFC) in SAP, which ensures messages are delivered exactly once without duplication through transaction safety. sRFC is synchronous RFC, aRFC is asynchronous, and qRFC is queued RFC - none provide EO semantics.
To answer this question, we need to understand the different types of RFC (Request for Comments) in the context of Quality of Service (QoS).
QOS(EO) stands for Quality of Service (QoS) with Exactly Once delivery semantics. This means that the QoS ensures that each message is delivered exactly once, without duplication or loss.
Now let's go through each option to understand why it is correct or incorrect:
Option A) sRFC - This option is incorrect because sRFC stands for Synchronous RFC, which is used for synchronous remote function calls in SAP systems. It is not related to QoS.
Option B) aRFC - This option is incorrect because aRFC stands for Asynchronous RFC, which is used for asynchronous remote function calls in SAP systems. It is not related to QoS.
Option C) qRFC - This option is incorrect because qRFC stands for Queue RFC, which is used for managing the execution of remote function calls in SAP systems. It is not related to QoS.
Option D) tRFC - This option is correct because tRFC stands for Transactional RFC, which provides exactly once delivery semantics for remote function calls in SAP systems. It ensures that each message is delivered exactly once, without duplication or loss. tRFC is the RFC type that corresponds to QOS(EO).
Therefore, the correct answer is option D) tRFC.
