The answer is to create a snapshot of the volume and then create a new volume in us-east-1b from that snapshot. This is the most efficient method because EBS volumes are strictly tied to their Availability Zone and cannot be attached to instances in a different AZ, so a snapshot is the only native way to copy the data across AZs without detaching or moving the original volume. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of EBS snapshot mechanics and the specific constraints of SAP HANA workloads, where minimizing downtime and avoiding unnecessary overhead like creating AMIs or using rsync over the network is critical. A common trap is assuming you can simply detach and reattach the volume to a different AZ, but that fails because volumes are AZ-scoped. Remember the memory tip: “Snapshots cross AZs, volumes stay put.”
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Network Topology
An SAP administrator runs the AWS CLI command shown in the exhibit to describe an EBS volume attached to an EC2 instance running SAP HANA. The instance is in the us-east-1a Availability Zone. The administrator needs to create a volume in us-east-1b and copy the data from the existing volume. What is the most efficient way to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a snapshot of the volume and then create a new volume in us-east-1b from the snapshot
Creating a snapshot of the existing volume is the most efficient way to copy data across Availability Zones. Then, create a new volume in us-east-1b from that snapshot. Detaching the volume and attaching it to an instance in us-east-1b is not possible because the volume is tied to its AZ. Creating an AMI is unnecessary overhead. Using rsync over the network would require an instance in the same AZ and network bandwidth.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use rsync to copy data from the instance to a new volume in us-east-1b over the network
Why it's wrong here
This would require network transfer and may be slower and less efficient than using snapshots.
✗
Detach the volume from the instance and attach it to an instance in us-east-1b
Why it's wrong here
EBS volumes are tied to their Availability Zone and cannot be attached to instances in a different AZ.
✓
Create a snapshot of the volume and then create a new volume in us-east-1b from the snapshot
Why this is correct
Snapshots are AZ-independent and can be used to create volumes in different AZs.

Read the scenario before looking for a memorised answer.
✗
Create an AMI from the instance and launch a new instance in us-east-1b
Why it's wrong here
This would include the OS and other volumes, which is more overhead than needed.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.

TExam Day Tips
→Underline the problem statement mentally.
→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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
