PAS-C01 Technology Practice Question
Network Topology
Refer to the exhibit. An SAP administrator is reviewing the EBS volume configuration for a SAP HANA /hana/data volume. The volume is 500 GB gp2 with DeleteOnTermination set to false. The instance is in us-east-1a. Which action should the administrator take to improve performance for SAP HANA?
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
✓
Modify the volume to gp3 and provision 5000 IOPS.
SAP HANA requires a minimum of 5000 IOPS for /hana/data. The gp2 volume provides 1500 IOPS (3 IOPS per GB). The administrator should either increase the volume size to at least 1667 GB to get 5000 IOPS, or change to gp3 with provisioned IOPS of 5000 or more. The best practice for SAP HANA is to use multiple volumes in RAID 0, but the question asks about improving performance for this volume. Changing to gp3 with higher IOPS is a direct improvement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Take a snapshot and create a new volume in us-east-1b.
Why it's wrong here
Changing availability zone does not improve performance.
- ✗
Enable encryption on the volume.
Why it's wrong here
Encryption does not improve performance.
- ✓
Modify the volume to gp3 and provision 5000 IOPS.
Why this is correct
gp3 allows provisioning higher IOPS independently of size.
- ✗
Set DeleteOnTermination to true.
Why it's wrong here
DeleteOnTermination does not affect performance.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
