PAS-C01 Practice Exam 63 — 20 Questions

Question 1

A company is migrating a large SAP NetWeaver system to AWS. The system includes an SAP HANA database and multiple SAP application servers. The company wants to minimize downtime and ensure data consistency during the migration. They plan to use SAP HANA system replication for the database and AWS Application Migration Service (AWS MGN) for the application servers. Which additional step is required to ensure that the application servers are consistent with the database at cutover?

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

Accepted Answer

Stop the SAP application servers on-premises before the final database takeover, and then start them on AWS after the database is available.. To ensure data consistency during a migration that uses SAP HANA system replication for the database and AWS MGN for application servers, the SAP application servers must be stopped before the final database takeover. This prevents any writes to the old database after the new one is promoted. After takeover, the application servers can be started on AWS and connected to the new database. Other options either propose unsupported tools or irrelevant features.

Answer

Enable SAP HANA multitenant database containers on the target system to isolate the application servers during the migration.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate ongoing changes from the on-premises SAP HANA database to Amazon EC2 after the initial system replication.

Answer

Configure AWS MGN to continuously replicate the application servers and then perform a final synchronization of the application servers with the database before cutover.

Question 2

An SAP Basis team is migrating an SAP S/4HANA system to AWS. The on-premises source runs SAP HANA 2.0 SPS06 on a scale-up appliance, and the target will run on an Amazon EC2 X2idn instance with Amazon EBS gp3 volumes. The team wants to use the SAP DMO procedure with SUM to combine the database migration and the SAP software upgrade in a single pass. Which prerequisite must be satisfied on the target before SUM/DMO can complete successfully?

Accepted Answer

The target system must have a supported SAP HANA revision installed and the SAP Host Agent plus SUM must be able to reach the SAP Support Portal for the required DMO and upgrade packages.. SUM/DMO depends on a supported SAP HANA revision on the target and on access to the required DMO and upgrade packages from the SAP Support Portal or a staged directory. Memory, filesystem layout, and source topology are not prerequisites in the way they are sometimes assumed. Meeting the software availability and revision requirements lets the combined migration and upgrade proceed.

Answer

The target EC2 instance must have at least twice the memory of the source appliance so that DMO can hold both the old and new database versions in memory.

Answer

The target Amazon EBS volumes must be configured with the same disk sizes and mount points as the source, including the original /hana/data and /hana/log layout.

Answer

The source system must be converted to a distributed SAP HANA scale-out configuration before DMO so that the target can be a scale-up instance.

Question 3

A company runs SAP ERP Central Component (ECC) on AWS with an Oracle database on a single EC2 instance. The database is on Amazon EBS volumes with a 15-minute RPO requirement. The operations team needs to restore the database to a specific point in time within the last 7 days after accidental data deletion. Which solution provides the required point-in-time recovery?

Accepted Answer

Use Oracle RMAN to back up to Amazon S3 and configure archive log mode with a 7-day retention, then restore using RMAN point-in-time recovery.. Oracle RMAN with archive log mode is the native mechanism for point-in-time recovery of an Oracle database. By backing up to Amazon S3 and retaining archived logs for 7 days, the team can restore to any moment within that window, satisfying both the 15-minute RPO and the 7-day PITR requirement. EBS snapshots and AWS Backup operate at the volume level and cannot roll forward through logs.

Answer

Enable EBS snapshots every 15 minutes and restore the most recent snapshot.

Answer

Enable Amazon RDS for Oracle with automated backups and use the RDS console to restore to a point in time.

Answer

Configure AWS Backup to take hourly backups of the EBS volumes and use AWS Backup restore to recover to a specific timestamp.

Question 4

A company is deploying SAP S/4HANA on AWS and must ensure that the SAP HANA database achieves the lowest possible latency for write-intensive operations. The database will run on an EC2 instance from the memory-optimized family. The company wants to use Amazon EBS volumes for the data and log areas. Which EBS volume type and configuration should be used for the HANA log volume to meet the latency requirement?

Accepted Answer

Provisioned IOPS SSD (io2 Block Express) with a size and IOPS ratio that supports sub-millisecond latency, attached to the instance.. The HANA log volume requires the lowest possible write latency, and io2 Block Express is the only EBS volume type engineered for sub-millisecond latency with high durability. Its ability to provision high IOPS and throughput per volume, combined with direct instance attachment, ensures the consistent performance needed for write-intensive log operations. Other volume types either lack the necessary latency characteristics or are optimized for different workloads.

Answer

General Purpose SSD (gp3) with a baseline of 3,000 IOPS and 125 MB/s, relying on burst credits for peak writes.

Answer

Cold HDD (sc1) with a large volume size to minimize cost while providing adequate latency for log writes.

Answer

Throughput Optimized HDD (st1) with a large volume size to maximize burst throughput for the log volume.

Question 5

A company is migrating a small SAP Business One system to AWS. The system uses Microsoft SQL Server as the database. The company wants to minimize the migration effort and use a managed database service. Which AWS service should they use for the database?

Accepted Answer

Amazon RDS for SQL Server. SAP Business One requires a relational database, and Microsoft SQL Server is a supported option. Amazon RDS for SQL Server provides a managed environment that reduces operational effort while meeting the application's requirements. The other services are either non‑relational or not designed for transactional workloads.

Answer

Amazon Redshift

Answer

Amazon ElastiCache for Redis

Answer

Amazon DynamoDB

Question 6

An SAP Basis team is deploying a new SAP S/4HANA production system on AWS. The database layer will run on Amazon EC2 with SAP HANA, and the team wants a storage configuration for the HANA data and log volumes that provides the lowest and most consistent latency. Which storage option should the team choose for the HANA data and log volumes?

Accepted Answer

Provisioned IOPS SSD (io2 Block Express) EBS volumes attached to the HANA instance, with IOPS and throughput sized to the SAP HANA storage KPIs.. SAP HANA data and log volumes require block storage with very low, consistent latency and provisioned IOPS. io2 Block Express EBS volumes meet the SAP HANA storage KPIs and are the validated option for EC2-based HANA deployments, while object stores and network file systems cannot deliver the required block-level performance.

Answer

Amazon S3 buckets mounted through a file gateway to provide virtually unlimited capacity for HANA data and log files.

Answer

Amazon FSx for Lustre file system mounted on the HANA instance to serve data and log volumes over the network.

Answer

General Purpose SSD (gp3) EBS volumes sized at 16,000 IOPS and 1,000 MiB/s to balance cost and performance.

Question 7

A company runs SAP NetWeaver on AWS and uses an Application Load Balancer (ALB) to distribute traffic to multiple SAP Web Dispatcher instances. The operations team notices that during peak loads, some user sessions are being routed to a different Web Dispatcher instance, causing session loss. Which configuration change should be made to ensure session stickiness?

Accepted Answer

Enable sticky sessions on the ALB target group using duration-based stickiness with an appropriate cookie.. Application Load Balancer supports duration-based sticky sessions via a cookie, which binds a user's session to a specific target. This ensures that all requests from that user during the session are routed to the same SAP Web Dispatcher instance, preventing session loss. The other options do not provide session affinity; NLB lacks cookie-based stickiness, and algorithm changes or cross-zone balancing do not bind sessions to a target.

Answer

Enable cross-zone load balancing on the ALB to ensure even distribution across all targets.

Answer

Configure the ALB to use the least outstanding requests algorithm instead of round robin.

Answer

Replace the ALB with a Network Load Balancer (NLB) and enable sticky sessions on the NLB target group.

Question 8

A company is deploying a new SAP NetWeaver application server on AWS. The SAP application must be able to communicate with the HANA database and other SAP components within the same VPC. The company wants to minimize latency and ensure that the application servers can be quickly scaled. Which AWS service should be used to provide a virtual network for the SAP deployment?

Accepted Answer

Amazon Virtual Private Cloud (Amazon VPC). Amazon VPC is the foundational service for creating a virtual network in AWS. It allows you to define subnets, route tables, and gateways, enabling secure and efficient communication between SAP application servers and the HANA database. Other services like Direct Connect, Transit Gateway, and Route 53 serve different networking purposes and do not provide the core virtual network.

Answer

AWS Direct Connect

Answer

AWS Transit Gateway

Answer

Amazon Route 53

Question 9

A company runs SAP S/4HANA on AWS with the HANA database on an x1e.32xlarge EC2 instance. The system must be highly available across two Availability Zones within a single AWS Region. The company requires an RPO of zero and an RTO of less than 15 minutes. Which approach should be used to meet these requirements?

Accepted Answer

Deploy SAP HANA with synchronous replication to a secondary EC2 instance in a different Availability Zone using SUSE HAE, and use an overlay IP address for automatic failover.. SUSE HAE with synchronous replication across Availability Zones is the recommended AWS solution for SAP HANA high availability with zero data loss and rapid failover. The overlay IP ensures seamless reconnection. Other options fail to meet RPO=0 or RTO<15 minutes, or use unsupported services.

Answer

Deploy SAP HANA on a single EC2 instance with frequent EBS snapshots every 5 minutes, and restore from snapshot in case of failure.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate SAP HANA data to a standby instance in another Availability Zone, and manually promote the standby during a failure.

Answer

Configure SAP HANA system replication in asynchronous mode to a secondary instance in another Availability Zone, and use an Application Load Balancer to distribute connections.

Question 10

A company is deploying SAP Business Suite on AWS and needs to ensure that the SAP application servers can automatically scale based on workload. The application servers are stateless and run on Amazon EC2 instances. Which AWS service should be used to automatically adjust the number of application server instances?

Accepted Answer

AWS Auto Scaling. AWS Auto Scaling is the correct service to automatically adjust the number of EC2 instances for stateless SAP application servers. It integrates with Elastic Load Balancing to distribute traffic and can scale based on CloudWatch metrics. The other services are either not designed for SAP workloads or do not provide the required control over EC2 instances.

Answer

Amazon ECS with AWS Fargate

Answer

AWS Elastic Beanstalk

Answer

AWS Lambda

Question 11

A company is deploying SAP NetWeaver on AWS and needs to ensure that the SAP application servers can communicate with the SAP HANA database with the lowest possible latency. The SAP application servers and the HANA database will be in the same AWS Region. Which AWS networking configuration should the company use?

Accepted Answer

Place the application servers and the HANA database in the same VPC and the same subnet, and enable enhanced networking on the EC2 instances.. The lowest latency is achieved by placing both SAP application servers and the HANA database in the same VPC and subnet, and enabling enhanced networking on the EC2 instances. This minimizes network paths and maximizes performance, which is critical for SAP. Other options introduce additional network components or disable performance features.

Answer

Place the application servers in a public subnet and the HANA database in a private subnet, and use an internet gateway for communication.

Answer

Place the application servers and the HANA database in separate VPCs and connect them using AWS Transit Gateway with equal-cost multi-path (ECMP) routing.

Answer

Place the application servers and the HANA database in the same subnet but disable enhanced networking to reduce overhead.

Question 12

A company is migrating a mission-critical SAP S/4HANA system to AWS. The system uses SAP HANA with a large dataset. The migration must minimize downtime and ensure data consistency. The team plans to use AWS DataSync for the /hana/data and /hana/log volumes from on-premises NFS storage to Amazon EFS. Which statement about this plan is accurate?

Accepted Answer

AWS DataSync can copy the HANA data and log files to Amazon EFS, but HANA does not support running on EFS; the target must use Amazon EBS or FSx for Lustre.. SAP HANA requires block-level storage such as Amazon EBS or FSx for Lustre for data and log volumes. Amazon EFS is not supported for HANA, despite being a scalable file system. AWS DataSync can transfer files to EFS, but the target architecture would be invalid for HANA. The correct approach involves using DataSync to move data to a supported storage service or using a database-level migration method like HANA system replication or backup/restore.

Answer

AWS DataSync supports SAP HANA system replication, so it can be used to set up a standby HANA system on AWS with minimal downtime.

Answer

AWS DataSync can copy the HANA data and log files to Amazon EFS, and HANA can run on EFS if the EFS file system is provisioned with sufficient throughput.

Answer

AWS DataSync can copy the HANA data and log files directly to Amazon EBS volumes, and HANA will start without additional configuration.

Question 13

A company is planning to migrate its SAP Business Suite on Oracle database to AWS. The database is currently running on physical servers with high memory and I/O requirements. The company wants to minimize downtime during the migration and ensure that the target environment meets SAP certification requirements. Which AWS service should be used to perform the migration with minimal downtime?

Accepted Answer

SAP-certified EC2 instances with Oracle Database on EC2, using Oracle Data Guard for replication. To migrate SAP Business Suite on Oracle to AWS with minimal downtime, the recommended approach is to use SAP-certified EC2 instances and set up Oracle Data Guard for replication from on-premises to AWS. This allows for a controlled switchover with minimal downtime and ensures the target environment meets SAP certification. Other options like RDS for Oracle, AWS MGN, or Snowball Edge either do not meet certification requirements, cause excessive downtime, or are not designed for database replication.

Answer

AWS Application Migration Service (AWS MGN) to replicate the entire server to EC2

Answer

AWS Snowball Edge to transfer database backups to Amazon S3 and then restore to EC2

Answer

AWS Database Migration Service (AWS DMS) with Oracle as source and Amazon RDS for Oracle as target

Question 14

A company runs SAP S/4HANA on AWS with a single HANA database tenant on an r5.12xlarge EC2 instance (48 vCPUs, 384 GiB memory). The SAP application servers run on separate c5.4xlarge instances. The company now needs to add a second HANA tenant for a non-production copy of the same system. The existing instance has 384 GiB memory, and the production tenant consumes approximately 200 GiB. The non-production tenant will require at least 120 GiB. Which action should the company take to satisfy the requirement?

Accepted Answer

Resize the EC2 instance to an instance type with at least 512 GiB memory and configure SAP HANA multiple containers (MDC) to host both tenants.. SAP HANA multiple containers (MDC) allows multiple tenant databases within a single SAP HANA system. The existing r5.12xlarge has 384 GiB memory, and the production tenant uses 200 GiB. Adding a 120 GiB tenant exceeds available memory. Resizing to an instance with at least 512 GiB (e.g., r5.16xlarge) provides enough memory for both tenants, and MDC is supported on virtualized EC2 instances. This satisfies the requirement without unnecessary bare-metal hardware or separate systems.

Answer

Enable SAP HANA dynamic tiering on the existing instance to offload the non-production tenant's data to disk, allowing both tenants to run within 384 GiB.

Answer

Keep the current instance and create a second HANA system on a new EC2 instance, then use SAP HANA system replication to sync the non-production tenant.

Answer

Resize the EC2 instance to a bare-metal instance type with at least 768 GiB memory and enable SAP HANA multiple containers (MDC) on that instance.

Question 15

A company is planning to migrate an SAP Business Warehouse system running on SAP HANA to AWS. The migration team wants to validate that the target Amazon EC2 instance and storage configuration will meet the SAP HANA performance and sizing requirements before the production cutover. Which AWS resource should the team consult to confirm the certified instance types and storage configurations for SAP HANA on AWS?

Accepted Answer

The SAP HANA hardware directory and the AWS SAP HANA certification documentation. SAP HANA certification is defined by SAP's hardware directory, with AWS publishing the corresponding certified EC2 instance types and storage configurations for HANA on AWS. Consulting these authoritative sources confirms that the target instance and storage meet production requirements before cutover. Pricing tools, Trusted Advisor, and pilot CloudWatch metrics do not provide certification data and cannot validate an unsupported configuration.

Answer

The AWS Pricing Calculator

Answer

AWS Trusted Advisor

Answer

Amazon CloudWatch metrics from a pilot instance

Question 16

A company is migrating a large SAP HANA database (12 TB) to AWS using SAP HANA system replication. The source is on-premises, and the target is an Amazon EC2 instance. The network bandwidth between the sites is 1 Gbps, and the initial replication is expected to take several days. The company wants to minimize the impact on the production system during the initial replication. Which configuration should be used for the initial replication to reduce the load on the source system?

Accepted Answer

Perform a backup on the source, transfer it to AWS, and then start system replication.. Performing a backup and transferring it to AWS allows you to seed the target database without continuously reading from the production source. After the backup is restored on the target, system replication can be started to synchronize the delta changes, which is a much smaller load on the source. This approach is recommended for large databases over limited bandwidth.

Answer

Use asynchronous replication with a high log replay backlog.

Answer

Increase the network bandwidth to 10 Gbps to speed up the initial replication.

Answer

Use SAP HANA multitenant database containers to isolate the replication process.

Question 17

A company runs SAP NetWeaver on AWS and wants to automate the patching of the underlying Amazon EC2 instances for both Linux and Windows operating systems. The operations team needs a centralized service that can apply patches on a schedule and report compliance. Which AWS service should be used?

Accepted Answer

AWS Systems Manager Patch Manager. AWS Systems Manager Patch Manager provides a centralized, automated way to patch EC2 instances running Linux and Windows. It integrates with maintenance windows to schedule patching and with Systems Manager Compliance to report on patch status. This makes it the ideal service for automating patching in an SAP on AWS environment, reducing manual effort and ensuring consistency.

Answer

AWS Config

Answer

AWS OpsWorks for Puppet Enterprise

Answer

Amazon Inspector

Question 18

A company is running an SAP S/4HANA system on AWS. The application servers are on Amazon EC2 instances in a private subnet, and the SAP HANA database is on an Amazon EC2 instance in another private subnet. The company wants to ensure that the application servers can resolve the database hostname and that traffic between them is encrypted in transit. The company also wants to minimize management overhead. Which solution should be implemented?

Accepted Answer

Use Amazon Route 53 private hosted zone for DNS resolution and enable encryption using TLS on the SAP HANA database.. Using a Route 53 private hosted zone provides internal DNS resolution for the SAP HANA database hostname, and enabling TLS on SAP HANA encrypts communication between the application servers and the database. This combination is fully managed and requires minimal operational effort, unlike solutions involving Direct Connect, load balancers, or PrivateLink, which are either irrelevant or add unnecessary complexity.

Answer

Use AWS Cloud Map for service discovery and enable encryption using AWS PrivateLink.

Answer

Use AWS Direct Connect with a public virtual interface for DNS and enable IPsec VPN for encryption.

Answer

Configure an Application Load Balancer to distribute traffic to the database and use AWS Certificate Manager for encryption.

Question 19

A company runs SAP NetWeaver on AWS and uses AWS Backup to protect its Amazon EBS volumes. The compliance team requires that backup jobs for the SAP production account be isolated from the account's own administrators, so that even an account administrator cannot delete recovery points. Which AWS Backup feature should be implemented to meet this requirement?

Accepted Answer

Enable AWS Backup Vault Lock in compliance mode on the backup vault.. AWS Backup Vault Lock in compliance mode enforces a WORM policy that even the account root user cannot bypass. This is the only option that prevents account administrators from deleting SAP recovery points, meeting the strict compliance requirement. Other options either manage cost, rely on modifiable IAM policies, or add redundancy without preventing deletion.

Answer

Configure an AWS Backup lifecycle policy to transition recovery points to cold storage after 30 days.

Answer

Attach an IAM policy to the backup vault that denies backup:DeleteRecoveryPoint to all principals.

Answer

Enable AWS Backup Cross-Region Backup to copy recovery points to a secondary region.

Question 20

A company is running SAP NetWeaver on AWS and wants to use Amazon FSx for NetApp ONTAP for the shared file system that stores SAP transport files and global directories. The system must be highly available across two Availability Zones. Which TWO configurations are required to meet these requirements? (Choose two.)

Accepted Answer

Mount the file system on each SAP application server using the NFS protocol.. To meet HA and shared storage requirements for SAP NetWeaver on AWS, the FSx for NetApp ONTAP file system must be deployed in a Multi-AZ configuration for automatic failover, and the application servers must mount it using NFS, which is the supported protocol for Linux-based SAP systems. SMB is for Windows, and the other options do not apply.

Answer

Create an AWS Storage Gateway file gateway to front the FSx for NetApp ONTAP file system.

Answer

Enable Amazon S3 Intelligent-Tiering for the file system's storage.

Answer

Configure the file system to use the SMB protocol for all application servers.
