PAS-C01 Operations and Maintenance Practice Question
An SAP administrator receives an alert that the HANA database has switched to read-only mode. The administrator checks the disk space and finds that the /hana/data volume is 100% full. What is the most efficient way to resolve this issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the size of the EBS volume using the console or CLI
EBS volumes can be increased in size online without downtime using the AWS Management Console or CLI, providing immediate additional space to resolve the read-only issue. Option A is incorrect because deleting backup files may not free enough space and is not a long-term solution. Option B is incorrect because restarting the database does not add storage space. Option C is incorrect because creating a new EC2 instance with larger disks requires migration and causes unnecessary downtime compared to simply increasing the EBS volume size.
