Topic #: 1

[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

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 QAT 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 (io2) Amazon Elastic Block Store (Amazon EBS) volumes.
The entire development team 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. The company wants to optimize infrastructure cost for the existing AWS resources.
How can the SAP solutions architect meet these requirements with the LEAST amount of administrative effort?

A. Use a Spot Fleet instead of the Reserved Instances and On-Demand Instances.
B. Use 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.
C. Make the SAP basis team available 24 hours a day, 7 days a week to use the AWS CLI to stop and start the development and sandbox EC2 instances manually.
D. Change the EBS volume type to Throughput Optimized HDD (st1) for the /hana/data and /hana/log file systems for the production and non-production SAP HANA databases.

Selected Answer: B

B: Amazon EventBridge can automate your AWS services and respond to system events such as application availability issues or resource changes. Events from AWS services are delivered to EventBridge in near-real time. You can write simple rules to indicate which events are of interest to you and what automated actions to take when an event matches a rule. Amazon CloudWatch Alarms watches a single metric over a time period you specify and performs one or more actions based on the value of the metric relative to a threshold over time. Therefore, in this scenario, you can automate stopping of the development and sandbox EC2 instances during the off-peak hours to save costs without requiring the SAP basis team to manually stop and start the instances, which will save time and reduce administrative effort.
