Answer: io2 - Provisioned IOPS SSD

Question 2

Cost-effective storage for infrequently accessed log files?

Answer: sc1 - Cold HDD

Question 3

Big data analytics requiring high throughput?

Answer: st1 - Throughput Optimized HDD

Snapshot Scenarios

Question 4

How to copy encrypted snapshot to another region?

Answer: Copy with re-encryption using destination region KMS key

Question 5

Restore from snapshot with immediate full performance?

Answer: Enable Fast Snapshot Restore (FSR)

Question 6

Automate daily snapshots with 30-day retention?

Answer: Use Data Lifecycle Manager (DLM)

Security & Encryption Questions

Question 7

How to encrypt existing unencrypted EBS volume?

  • • Create snapshot of volume
  • • Copy snapshot with encryption
  • • Create new volume from encrypted snapshot
  • • Replace original volume

Question 8

Enable encryption for all new EBS volumes?

  • • Enable EBS encryption by default
  • • Configure at account level
  • • Set default KMS key
  • • Apply per region

Performance Scenarios

Question 9

gp2 volume performance degrading after initial burst?

Answer: Upgrade to gp3 or increase volume size

Question 10

Inconsistent EBS performance on EC2 instance?

Answer: Enable EBS-optimized instance

Question 11

Monitor EBS volume performance metrics?

Answer: Use CloudWatch VolumeReadOps, VolumeWriteOps

Advanced Features

Question 12

Share EBS volume between multiple EC2 instances?

Answer: Use Multi-Attach with io1/io2 and cluster file system

Question 13

Increase EBS volume size without downtime?

Answer: Use Elastic Volumes feature

Question 14

Oracle RAC cluster storage requirements?

Answer: io2 Multi-Attach with cluster-aware file system

Scenario-Based Questions

Scenario 1: Database Migration

Company migrating 2TB database requiring 15,000 IOPS with 99.99% uptime SLA.

Solution:

  • • Use io2 volume type
  • • Enable Multi-AZ deployment
  • • Configure automated backups
  • • Use EBS-optimized instances

Scenario 2: Disaster Recovery

Critical application needs cross-region backup with 4-hour RTO requirement.

Solution:

  • • Automated cross-region snapshot copying
  • • Enable Fast Snapshot Restore in DR region
  • • Use Data Lifecycle Manager
  • • Test restore procedures regularly

Common Mistakes

Mistake 1

Using HDD volumes as boot volumes

Mistake 2

Expecting Multi-Attach to work with standard file systems

Mistake 3

Not extending file system after volume resize

Exam Tips

Remember IOPS Limits

gp3: 16,000 | io2: 64,000 | gp2: 16,000

Know Volume Types

Match workload requirements to appropriate type

Understand Encryption

Cannot directly encrypt existing volumes

Key EBS Exam Concepts

  • • Volume types: gp3 (latest general purpose), io2 (high IOPS), st1 (throughput), sc1 (cold)
  • • Snapshots are incremental, stored in S3, and can be copied across regions
  • • Multi-Attach requires io1/io2 volumes and cluster-aware file systems
  • • Encryption uses KMS, can be enabled by default, and cannot be removed once enabled
  • • EBS-optimized instances provide dedicated bandwidth for consistent performance
