Topic #: 10

An SAP solutions architect is leading the SAP basis team for a company. The company's SAP landscape includes SAP HANA database instances for the following systems sandbox development quality assurance test {QAT} system performance test (SPT) and production. The sandbox development and OAT systems are running on Amazon EC2 On-Demand Instances. The SPT and production systems are running on EC2 Reserved Instances All the EC2 instances are using Provisioned IOPS SSO (K)2) Amazon Elastic Block Store (Amazon EBS) volumes.

The entire development learn is in the same time zone and works from 8 AM to 6 PM. The sandbox system is for research and testing that are not critical. The SPT and production systems are business critical The company runs load-testing jobs and stress-testing jobs on the QAT systems overnight to reduce testing duration.

AUse a Spot Fleet instead of the Reserved Instances and On-Demand Instances

BUse Amazon EventBridge (Amazon CloudWatch Events) and Amazon CloudWatch alarms to stop the development and sandbox EC2 instances from 7 PM every night to 7 AM the next day

DChange the EBS volume type to Throughput Optimized HDD (sti) for the /hana/data and nana, log file systems for the production and non-production SAP HANA databases

Show Suggested Answer

Suggested Answer: B

B is correct because using Amazon EventBridge (Amazon CloudWatch Events) and Amazon CloudWatch alarms to stop the development and sandbox EC2 instances from 7 PM every night to 7 AM the next day reduces the infrastructure cost for the non-critical systems that are not used during that time. This solution also requires the least amount of administrative effort as it is automated and does not require manual intervention.
