PAS-C01 Practice Test 18 — 15 Questions

Question 1

A company is designing a disaster recovery (DR) strategy for SAP S/4HANA on AWS. The primary region is us-east-1 and the DR region is us-west-2. The RPO is 15 minutes and RTO is 1 hour. Which approach should be used to replicate SAP HANA data?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Configure HANA System Replication across regions. HANA System Replication (HSR) is the only option that meets the 15-minute RPO and 1-hour RTO for SAP HANA data replication across regions. HSR uses log-based asynchronous replication to continuously ship redo logs to the DR region, enabling near-real-time data synchronization with minimal data loss. This is the native SAP-recommended method for cross-region DR of SAP HANA databases.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication

Answer

Use Amazon S3 Cross-Region Replication for backup files

Answer

Use AWS Backup cross-region copy of EBS snapshots

Question 2

A company is running SAP Business Suite on AWS with a Microsoft SQL Server database. The operations team needs to implement automated database backups with point-in-time recovery. Which AWS service should be used to achieve this?

Accepted Answer

AWS Backup. AWS Backup (option B) is the correct service for automated database backups with point-in-time recovery for SQL Server running on EC2. It supports SQL Server databases on EC2 and provides automated backup scheduling and point-in-time recovery capabilities. Option A (AWS Storage Gateway) is for hybrid cloud storage, not database backup. Option C (AWS DMS) is for database migration, not backup. Option D (Amazon RDS for SQL Server) is a managed database service, but since the SQL Server is on EC2, RDS does not apply.

Answer

AWS Storage Gateway

Answer

AWS Database Migration Service (DMS)

Answer

Amazon RDS for SQL Server

Question 3

A company is migrating its SAP ERP system to AWS and wants to minimize downtime during the migration. Which THREE strategies should be considered? (Choose three.)

Accepted Answer

Use Amazon S3 Transfer Acceleration to speed up data transfer.. Amazon S3 Transfer Acceleration is correct because it uses AWS edge locations to accelerate uploads to S3 over long distances, leveraging optimized network paths and the TCP protocol to reduce latency and improve throughput. For large SAP database exports, this can significantly reduce the time required for the initial data transfer to AWS, thereby minimizing overall migration downtime.

Answer

Shut down the source system and perform a full database export to S3.

Answer

Perform a full export and import of the SAP system during a maintenance window.

Question 4

An SAP system administrator needs to apply an operating system patch to an Amazon EC2 instance running SAP NetWeaver. The instance is part of an Auto Scaling group. What is the BEST approach to minimize downtime?

Accepted Answer

Use a rolling update by updating the launch configuration and performing an instance refresh.. An instance refresh in an Auto Scaling group allows you to apply a new launch configuration (which includes the patched AMI or user data) to all instances in a rolling, controlled manner. This minimizes downtime by replacing instances one at a time or in batches, ensuring the SAP NetWeaver application remains available throughout the process. Detaching, stopping, or terminating individual instances would cause unnecessary disruption or require manual reattachment, which is not optimal for high-availability SAP landscapes.

Answer

Detach the instance from the Auto Scaling group, apply the patch, and reattach.

Answer

Stop the instance, apply the patch, and start it.

Answer

Terminate the instance and let Auto Scaling launch a new one with the patch.

Question 5

A large enterprise is migrating its SAP S/4HANA system to AWS. The system includes a production SAP HANA database (4 TB) and a development SAP HANA database (1 TB). The migration strategy is to use SAP HANA System Replication (HSR) for both databases to EC2 instances in the same AWS region. The company has a compliance requirement that the production database must be in a different AWS account than the development database. The network between on-premises and AWS uses AWS Direct Connect with 10 Gbps bandwidth. During the test migration, the HSR replication for the development database works, but the production database fails to establish replication. The error log shows: "HSR connection timed out." The security groups and network ACLs for the production target EC2 instance allow inbound traffic on port 30101 from the on-premises source IP. What is the most likely cause of the failure?

Accepted Answer

The production target EC2 instance is in a different AWS account, and there is no VPC peering or Transit Gateway between the accounts to allow connectivity.. HSR requires communication between the source and target HANA instances. If the target is in a different account, VPC peering or Transit Gateway is needed for cross-account connectivity. Option A is correct because cross-account communication requires VPC peering or Transit Gateway. Option B is wrong because the port is correct. Option C is wrong because HSR does not use port 443. Option D is wrong because the source is on-premises, not in another AWS account.

Answer

The production source HANA instance is not configured to replicate to a different AWS account.

Answer

The production target EC2 instance is using the wrong port for HSR.

Answer

The security group on the production target EC2 instance does not allow inbound traffic on port 443.

Question 6

A company is migrating its SAP ECC system to SAP S/4HANA on AWS. The current database is running on Oracle. They want to minimize downtime during the migration. Which TWO services or features should they consider to achieve a near-zero downtime migration? (Select TWO.)

Accepted Answer

Use AWS Snowball to transfer the initial Oracle data dump to AWS.. To achieve near-zero downtime migration from Oracle to SAP HANA on AWS, two key services are recommended: AWS Snowball for the initial bulk data transfer to AWS, and AWS Database Migration Service (DMS) for ongoing replication of changes from Oracle to HANA. SAP HANA System Replication (HSR) is used for replication between two HANA systems, not for heterogeneous migration from Oracle. EC2 Hibernate and EBS Snapshots are not designed for live database migration across different engines.

Answer

Use SAP HANA System Replication (HSR) for the final synchronization.

Answer

Use EC2 Hibernate to pause the source instance during cutover.

Answer

Use Amazon EBS Snapshots for point-in-time recovery and replication.

Question 7

An architect is designing a disaster recovery (DR) solution for an SAP ERP system on AWS. The primary site is in us-east-1 and the DR site is in us-west-2. The SAP application uses an Oracle database. The RTO is 4 hours and RPO is 1 hour. Which solution meets these requirements with the least operational overhead?

Accepted Answer

Configure AWS Database Migration Service (DMS) with ongoing replication from the primary Oracle database to a standby in us-west-2. AWS Database Migration Service (DMS) with ongoing replication provides continuous change data capture (CDC) from the primary Oracle database to a standby in us-west-2, meeting the 1-hour RPO and 4-hour RTO with minimal operational overhead. DMS handles schema conversion, replication, and failover without requiring manual intervention or complex Oracle licensing, making it the most efficient choice for cross-region DR.

Answer

Set up Oracle Active Data Guard between the primary and DR regions

Answer

Take daily EBS snapshots of the database volumes and copy them to us-west-2, then restore using the snapshots

Answer

Use AWS Backup to copy EC2 AMIs and RDS snapshots to us-west-2 every hour

Question 8

A company is migrating an on-premises SAP ERP system to AWS. The system uses a large Oracle database. The migration must minimize downtime. Which AWS service should be used for the database migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can migrate databases with minimal downtime by using ongoing replication. Option A is incorrect because AWS SMS is designed for server migration, not database migration. Option B is incorrect because AWS Application Migration Service (MGN) is also for server migration. Option C is incorrect because AWS Schema Conversion Tool (SCT) assists with schema and code conversion but is not a full database migration service. Option D is correct because AWS Database Migration Service (DMS) can migrate Oracle databases to AWS with minimal downtime using continuous replication.

Answer

AWS Server Migration Service (SMS)

Answer

AWS Application Migration Service (MGN)

Answer

AWS Schema Conversion Tool (SCT)

Question 9

A company is planning to migrate a large SAP HANA database to AWS using AWS Snowball Edge devices. The database size is 50 TB and the migration must be completed within a week. Which TWO actions should the company take to ensure a successful migration?

Accepted Answer

Order multiple Snowball Edge devices to transfer data in parallel.. Snowball Edge devices have a usable storage capacity of up to 80 TB per device, but to transfer 50 TB within a one-week window, using multiple devices in parallel significantly reduces the total transfer time. Parallel data transfer allows the company to split the workload across devices, maximizing throughput and meeting the tight migration deadline.

Answer

Use AWS Direct Connect to accelerate data transfer from Snowball Edge to AWS.

Answer

Split the data into smaller chunks because each Snowball Edge can only hold 10 TB.

Answer

Copy the data directly to an Amazon S3 bucket using the Snowball Edge client.

Question 10

A company runs SAP HANA on AWS using a scale-up configuration. The system is experiencing high CPU utilization on the HANA server during peak load. The SAP administrator wants to add more CPU resources without disruption. Which action should be taken?

Accepted Answer

Add an additional HANA node to create a scale-out configuration and distribute the load.. Adding an additional HANA node to create a scale-out configuration allows the system to distribute the workload across multiple nodes, providing additional CPU resources without downtime. SAP HANA supports scale-out configurations where new nodes can be added online using the 'ALTER SYSTEM ADD WORKER' command, enabling CPU scaling without restarting the existing system.

Answer

Enable Multi-AZ deployment for high availability.

Answer

Change the EC2 instance type to a larger size using the AWS Management Console.

Answer

Increase the provisioned IOPS on the EBS volumes.

Question 11

A company is designing an SAP HANA disaster recovery (DR) solution on AWS. The primary site is in us-east-1, and the DR site is in us-west-2. The RPO must be less than 15 minutes, and the RTO must be less than 2 hours. Which replication strategy meets these requirements?

Accepted Answer

SAP HANA system replication with synchronous mode and pre-provisioned DR instances.. SAP HANA system replication with synchronous mode ensures that every committed transaction is replicated to the DR site before acknowledgment, meeting the <15-minute RPO. Pre-provisioned DR instances in us-west-2 allow rapid failover, enabling the <2-hour RTO by eliminating the need to provision infrastructure during recovery.

Answer

SAP HANA log shipping to an S3 bucket in the DR region.

Answer

S3 cross-region replication for HANA data files.

Answer

EBS snapshot replication to the DR region every 15 minutes.

Question 12

An SAP HANA administrator runs the AWS CLI command shown in the exhibit. The volume is attached to an SAP HANA server. The HANA database is experiencing low write throughput. Which action would most likely improve performance?

Accepted Answer

Change the volume type to io2 and provision 6000 IOPS.. The AWS CLI command output shows the volume is a gp2 volume with a size of 500 GB. gp2 volumes provide a baseline IOPS of 3 per GB, so this volume has 1,500 baseline IOPS. For SAP HANA workloads requiring high write throughput, gp2's burst model is insufficient. Changing to io2 Block Express with provisioned 6000 IOPS delivers consistent, high-performance IOPS needed for sustained write operations, directly addressing the low write throughput issue.

Answer

Detach the volume and reattach it to a different instance.

Answer

Increase the volume size to 1 TB to double the baseline IOPS.

Answer

Enable EBS optimization on the attached instance.

Question 13

Which TWO of the following are best practices for running SAP HANA on AWS? (Select TWO.)

Accepted Answer

Use EBS Snapshots for backup of HANA data volumes.. EBS Snapshots provide a consistent, crash-consistent backup mechanism for HANA data volumes when used with application-consistent procedures (e.g., pre-freeze/post-thaw scripts via AWS Backup or custom automation). Snapshots are block-level, incremental, and can be automated for point-in-time recovery, aligning with SAP HANA backup best practices on AWS.

Answer

Use Amazon EFS as the storage layer for HANA data files.

Answer

Use T3 instances for production to save costs.

Answer

Use Amazon RDS Multi-AZ for HANA database replication.

Question 14

A company is planning to migrate a critical application to AWS using the 7 Rs migration strategy. The application is currently running on a large VMware VM. Which THREE strategies are appropriate for this migration? (Choose three.)

Accepted Answer

Rehost: Use AWS VM Import/Export to migrate the VM to EC2. Rehost (A) is appropriate because AWS VM Import/Export allows you to migrate VMware VMs directly to Amazon EC2 as AMIs, enabling a lift-and-shift migration with minimal changes. This is a core 7 Rs strategy for moving existing virtualized workloads to AWS.

Answer

Retire: Decommission the application as it is no longer needed

Answer

Retain: Keep the application on-premises

Question 15

An SAP administrator runs the AWS CLI command shown in the exhibit for an EC2 instance running SAP HANA. The administrator notices that the /dev/sdf volume does not have DeleteOnTermination set to true. What is the impact of this configuration?

Accepted Answer

The volume will persist after instance termination, preserving data.. When the DeleteOnTermination attribute of an EBS volume is set to false (as indicated by the absence of 'true' in the AWS CLI output for /dev/sdf), the volume will not be automatically deleted when the EC2 instance is terminated. Instead, the volume enters a 'available' state and persists independently, preserving all data for later use or reattachment. This is critical for SAP HANA workloads where data volumes must survive instance termination for disaster recovery or migration scenarios.

Answer

The volume will be detached but not deleted.

Answer

The volume will be automatically deleted when the instance is terminated.

Answer

The volume cannot be attached to another instance.
