Quick Answer
The correct answer is AWS Elastic Disaster Recovery (AWS DRS). This service is purpose-built for enterprise workloads like SAP S/4HANA, providing continuous, block-level replication with sub-second recovery point objectives (RPO) and automated recovery orchestration, which directly supports the required 4-hour recovery time objective (RTO). On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of native disaster recovery services versus traditional backup solutions; a common trap is confusing AWS DRS with AWS Backup or manual snapshot strategies, which cannot guarantee sub-second RPO or automated failover within a strict RTO window. Remember that AWS DRS is the direct successor to CloudEndure Disaster Recovery and is optimized for SAP’s consistent state replication across Regions or Availability Zones. A helpful memory tip: DRS stands for “Disaster Recovery for SAP,” and the key metric to associate with it is sub-second RPO—if the question demands near-zero data loss and fast automated recovery, DRS is your service.
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 is planning to run SAP S/4HANA on AWS. They need to ensure that the SAP system can be restored within 4 hours in the event of a disaster. Which AWS service should be used to achieve this recovery time objective (RTO)?
AWS Elastic Disaster Recovery
DRS provides fast recovery for SAP systems.
EBS snapshots copied to another region
Why wrong: Snapshots alone may not meet RTO without automation.
AWS CloudEndure Disaster Recovery
Why wrong: CloudEndure is now part of DRS, but DRS is the current service.
Amazon S3 cross-region replication
Why wrong: S3 replication does not cover full system recovery.

Correct answer & explanation
AWS Elastic Disaster Recovery
AWS Elastic Disaster Recovery (AWS DRS) is the correct service because it provides continuous replication of SAP S/4HANA workloads with sub-second RPO and supports automated recovery orchestration, enabling restoration within the 4-hour RTO. It is the direct successor to CloudEndure Disaster Recovery and is purpose-built for enterprise applications like SAP, offering non-disruptive testing and fast failover to a secondary AWS Region or Availability Zone.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Snapshots alone may not meet RTO without automation.
AWS CloudEndure Disaster Recovery
Why it's wrong here
CloudEndure is now part of DRS, but DRS is the current service.
Amazon S3 cross-region replication
Why it's wrong here
S3 replication does not cover full system recovery.
Common exam traps
The trap here is that candidates confuse AWS Elastic Disaster Recovery with its predecessor name 'CloudEndure Disaster Recovery' (Option C), which is the same service but the exam expects the current AWS branding, or they mistakenly think periodic EBS snapshots (Option B) can achieve a 4-hour RTO for SAP without considering the recovery time for snapshot restoration and database consistency.
Detailed technical explanation
AWS Elastic Disaster Recovery uses continuous block-level replication at the volume layer via an agent installed on the source server, which sends data changes to a staging area in the target region. During a failover, it launches fully provisioned EC2 instances from the replicated volumes, and you can use launch templates to automate SAP-specific configurations (e.g., EBS optimization, instance types). A real-world scenario: if a primary region fails, AWS DRS can spin up the SAP system in the DR region within minutes, but you must ensure the target region has sufficient SAP-licensed instance capacity (e.g., r5.metal) to meet the 4-hour RTO.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
