PAS-C01 AWS Database Migration Service (DMS) 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. A key principle to apply: aWS Database Migration Service (DMS). 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 SAP application on an SAP HANA database in a single Availability Zone on AWS. The database is 2 TB in size. The company needs to implement a disaster recovery (DR) strategy with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. The DR region must be in a different AWS Region. Which solution meets these requirements with the LEAST operational overhead?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "least"

    Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

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

Use AWS Database Migration Service (DMS) to continuously replicate data from the HANA database to a HANA database in the DR region.

AWS Database Migration Service (DMS) with continuous replication (change data capture) can achieve an RPO of 15 minutes for a 2 TB SAP HANA database across AWS Regions. The RTO of 2 hours is achievable by provisioning the target HANA instance in advance and applying changes. This solution uses a fully managed AWS service, reducing operational overhead compared to manual scripting or third-party tools. While SAP HANA System Replication (HSR) is native, cross-region synchronous replication is not feasible due to latency; asynchronous HSR could meet the RPO but is not listed as an option. DMS provides continuous replication with minimal setup and monitoring, making it the best choice among the given options.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Configure SAP HANA System Replication (HSR) in a multitier setup with a primary in the source region and a synchronous secondary in the DR region. Use HANA takeover for failover.

    Why it's wrong here

    This option specifies a synchronous secondary in the DR region. Synchronous HSR across AWS Regions is infeasible because network latency would impact performance and may cause replication delays, violating the RPO. Asynchronous HSR would be required, but the option text does not specify asynchronous, making this answer incorrect.

  • Use AWS Database Migration Service (DMS) to continuously replicate data from the HANA database to a HANA database in the DR region.

    Why this is correct

    Correct. AWS DMS can continuously replicate HANA data with change data capture, meeting the RPO of 15 minutes. The target database can be pre-provisioned, and automated failover can be configured using DMS ongoing replication, achieving an RTO of 2 hours. This is a managed service, reducing operational overhead.

    Clue confirmation

    The clue word "least" in the question point toward this answer.

    Related concept

  • Deploy a second HANA node in a different Availability Zone in the same region and configure HANA System Replication. Use AWS Global Accelerator to route traffic to the standby.

    Why it's wrong here

    This option places the secondary HANA node in a different Availability Zone within the same region, failing to meet the requirement for a different AWS Region. Additionally, using Global Accelerator for database traffic is not standard practice and adds complexity.

  • Use AWS Backup to schedule daily snapshots of the HANA database and copy them to the DR region. In the event of a disaster, restore the latest snapshot to a new HANA instance.

    Why it's wrong here

    Daily snapshots provide an RPO of 24 hours, which exceeds the required 15 minutes. Restoring a snapshot and configuring the database cannot achieve an RTO of 2 hours reliably. This solution also requires manual intervention during recovery, increasing operational overhead.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap is that candidates assume SAP HANA System Replication is always the best solution for HANA DR, but synchronous replication across AWS Regions is not feasible due to latency. They may overlook AWS DMS as a viable managed alternative that can meet the RPO/RTO with lower operational overhead.

Detailed technical explanation

How to think about this question

SAP HANA System Replication uses log-based replication where the primary sends redo log entries to the secondary; in synchronous mode, the primary waits for acknowledgment from the secondary before committing a transaction, ensuring RPO=0. For cross-region setups, network latency must be below the HANA replication timeout (default 30 seconds) and bandwidth must sustain the log volume; a 2 TB database typically generates logs at 10-50 MB/s, requiring at least 1 Gbps dedicated link. The multitier setup allows a cascading replication to an additional site, but here a direct synchronous link to the DR region is used.

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.

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.
