- A
Share the AMI with the target region.
Why wrong: Sharing does not copy the AMI; it only allows other accounts to use it in the same region.
- B
Copy the AMI and underlying EBS snapshots to the DR region.
Copying the AMI and snapshots to the DR region allows launching an instance in that region, meeting the RTO.
- C
Use EBS snapshots directly in the DR region.
Why wrong: EBS snapshots are specific to a region; they cannot be used directly in another region.
- D
Configure AWS Backup to copy backups to the DR region.
Why wrong: While AWS Backup can copy backups, the question asks for the most efficient approach; copying the AMI and snapshot is the standard method.

SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs a critical database on an EC2 instance with an EBS volume. The administrator wants to create a disaster recovery plan that can recover the database in a different AWS Region within 4 hours. The database size is 1 TB. What is the MOST efficient approach to meet the RTO?
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
✓
Copy the AMI and underlying EBS snapshots to the DR region.
Option B is correct because copying the AMI and its underlying EBS snapshots to the DR region creates a fully independent, bootable image that can be launched as an EC2 instance in the target region. This approach directly supports the 4-hour RTO by allowing the administrator to pre-stage the AMI copy or initiate the copy on-demand, and then launch the instance from the copied AMI without needing to recreate the volume from individual snapshots or reconfigure instance metadata.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Use EBS snapshots directly in the DR region.
Why it's wrong here

Why it's wrong here
While AWS Backup can copy backups, the question asks for the most efficient approach; copying the AMI and snapshot is the standard method.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'sharing' an AMI (which only grants cross-account access, not cross-region availability) with 'copying' an AMI (which physically replicates the image to another region), leading them to select Option A despite it not enabling DR in a different region.
Detailed technical explanation
How to think about this question
When you copy an AMI to another region, AWS automatically copies the associated EBS snapshots and registers a new AMI in the destination region, preserving the block device mapping, instance metadata, and launch permissions. This process can be initiated via the AWS CLI, SDK, or Console, and the copy time depends on snapshot size and network transfer speed; for a 1 TB volume, incremental snapshots can reduce the initial copy time if the source AMI was created from an existing snapshot. In a real-world scenario, pre-copying the AMI to the DR region and keeping it updated with periodic copies ensures the RTO is met, as the administrator only needs to launch an instance from the pre-staged AMI.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
