You are migrating SAP to Azure. The ASCS application servers are in one Azure zone, and the SAP databaseserver in in a different Azure zone. ASCS/ERS is configured for high availability.During performance testing, you discover increased response times in Azure, even though the Azureenvironment has better computer and memory configurations than the on-premises environment.During the initial analysis, you discover an increased wait time for Enqueue.What are three possible causes of the increased wait time? Each correct answer presents a complete solution.NOTE: Each correct selection is worth one point.
C) misconfigured load balancer rules and health check probes for Enqueue and ASCS and D) active Enqueue replication and E) network latency between the database server and the SAP application servers
A) a missing Enqueue profile
B) disk I/O during Enqueue backup operations

[All AZ-120 Questions]

You are migrating SAP to Azure. The ASCS application servers are in one Azure zone, and the SAP database

server in in a different Azure zone. ASCS/ERS is configured for high availability.

During performance testing, you discover increased response times in Azure, even though the Azure

environment has better computer and memory configurations than the on-premises environment.

During the initial analysis, you discover an increased wait time for Enqueue.

What are three possible causes of the increased wait time? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Suggested Answer: C, D, E

E: The network latency across Availability Zones is not the same in all Azure regions. In some cases, you can deploy and run the SAP application layer across different zones because the network latency from one zone to the active DBMS VM is acceptable. But in some Azure regions, the latency between the active DBMS VM and the SAP application instance, when deployed in different zones, might not be acceptable for SAP business processes.

Yeah, I agree with E, that distance between zones can really add up!

B could be a factor too, disk I/O can slow things down during backups.

Surprised to see A as a potential cause, I thought that was always set up right!

I think C is also a strong possibility, load balancer misconfigurations can mess things up.

Definitely E, network latency can be a big issue.

I keep thinking about disk I/O issues. I recall a case study where backup operations slowed down response times significantly.

I wonder if the load balancer settings could be causing the delays. We practiced troubleshooting load balancer configurations, and it seems relevant.

I’m not entirely sure, but I think a missing Enqueue profile might lead to issues. We had a similar question about configuration problems in our last practice exam.

I remember we discussed network latency in class, especially how it can impact performance when servers are in different zones. That could definitely be a factor here.
