The answer is to use AWS Backup to schedule snapshots of the EBS volumes and copy them to the DR region. This approach meets the 1-hour RPO by taking snapshots every hour and satisfies the 4-hour RTO through automated restore procedures, all while minimizing changes to the existing SAP ASE environment. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding that AWS Backup provides a simple, agentless snapshot-based DR method that avoids complex replication setups like SAP ASE native replication or AWS DMS, which require significant licensing or ongoing change management. A common trap is assuming Multi-AZ or native replication is needed for cross-region DR, but snapshots copied between regions are the most straightforward solution for SAP ASE when RPO and RTO are moderate. Memory tip: think “snap and ship” for cross-region DR with AWS Backup.
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.
A company runs SAP Business Suite on AWS and wants to implement a disaster recovery (DR) solution with a Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 1 hour. The primary site is in us-east-1, and DR site will be in us-west-2. The database is running on SAP ASE. The company wants to minimize changes to the existing SAP environment and avoid complex replication setups. What is the most suitable DR approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Backup to schedule snapshots of the EBS volumes and copy them to the DR region.
Option A is correct. Using AWS Backup to take frequent snapshots of the database and application volumes and copying them to the DR region can meet the RPO of 1 hour if snapshots are taken every hour. Restoring from snapshots can be automated to meet the RTO. Option B is wrong because Database Migration Service is for ongoing replication, not backup/restore. Option C is wrong because SAP ASE native replication requires significant changes and licensing. Option D is wrong because Multi-AZ is for high availability within a region, not DR across regions.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Deploy a Multi-AZ database in the primary region.
Why it's wrong here
Multi-AZ does not provide cross-region DR.
✗
Set up SAP ASE native replication to a standby database in the DR region.
Why it's wrong here
Complex and requires licensing.
✓
Use AWS Backup to schedule snapshots of the EBS volumes and copy them to the DR region.
Why this is correct
Simple and meets RPO/RTO with proper scheduling.
Clue confirmation
The clue words "primary", "minimum / minimize" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use AWS Database Migration Service to continuously replicate data to the DR region.
Why it's wrong here
DMS requires source changes and may not be straightforward for SAP ASE.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
