PAS-C01 Technology Practice Question

This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 designing a disaster recovery (DR) strategy for its SAP environment on AWS. The primary region is us-east-1 and the DR region is us-west-2. The SAP application and database must be recoverable within 4 hours (RTO) and with a maximum data loss of 15 minutes (RPO). The database is SAP HANA. Which combination of services meets these requirements?

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.

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

Configure HANA System Replication (HSR) between the primary and DR regions, with a standby EC2 instance in us-west-2.

Option B is correct because HANA System Replication with log shipping provides low RPO (15 minutes) and can be combined with a standby instance in the DR region for failover within 4 hours. Option A is wrong because EBS snapshots alone may not achieve 15-minute RPO. Option C is wrong because DMS is for homogeneous migrations, not real-time replication. Option D is wrong because S3 is for backups, not replication.

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.

  • Use Amazon EBS snapshots replicated across regions, restoring in the DR region with a CloudFormation template.

    Why it's wrong here

    EBS snapshots are periodic and cannot guarantee 15-minute RPO; also, restoring large volumes takes time.

  • Back up the HANA database to Amazon S3 and copy the backup to the DR region using cross-region replication.

    Why it's wrong here

    Backup and restore typically have higher RPO and RTO than replication.

  • Configure HANA System Replication (HSR) between the primary and DR regions, with a standby EC2 instance in us-west-2.

    Why this is correct

    HSR provides near-synchronous replication with RPO as low as seconds, meeting the 15-minute requirement.

    Clue confirmation

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

    Related concept

    Static NAT maps one inside address to one outside address.

  • Use AWS Database Migration Service (DMS) with ongoing replication to an RDS for SAP HANA instance in the DR region.

    Why it's wrong here

    DMS is not designed for real-time replication of SAP HANA; HSR is the native solution.

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.
