PAS-C01 Practice Exam 67 — 20 Questions

Question 1

A company is migrating an SAP S/4HANA system to AWS using a homogeneous system copy with SWPM. The database is SAP HANA 2.0 SPS06 on an on-premises appliance. The migration team wants to use SAP HANA system replication to keep the target in sync and perform a near-zero-downtime cutover. The source and target are in different network segments with a 40 ms round-trip latency and no shared storage. Which statement correctly describes a constraint the team must account for when planning this replication-based cutover?

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

Accepted Answer

SAP HANA system replication in asynchronous mode can be used across the WAN link to avoid latency-induced primary performance degradation, accepting some potential data loss at cutover.. HANA system replication is log-based and does not need shared storage, so the shared-LUN constraint is false. Identical hardware is not required, and replication does not substitute for the SWPM system copy. Across a high-latency WAN link, synchronous modes would penalize primary commit times, so asynchronous replication is the appropriate choice, with the acknowledged risk of losing the last unshipped redo logs unless the application is quiesced and a final flush is forced before takeover.

Answer

SAP HANA system replication requires shared storage between primary and secondary sites, so the migration cannot proceed without presenting the same LUNs to both sites.

Answer

SAP HANA system replication requires the secondary to use identical hardware and the same SID as the primary, otherwise replication will not initialize.

Answer

SAP HANA system replication automatically performs the SWPM-based system copy, so the team does not need to run a separate homogeneous system copy step on the target.

Question 2

A company is migrating a large SAP Business Warehouse (BW) system on SAP HANA to AWS. The system uses a custom ABAP code that includes frequent SELECT statements on a large table without proper indexing. The migration team needs to ensure optimal performance after the migration. Which TWO actions should the team take to improve performance? (Choose two.)

Accepted Answer

Analyze the ABAP code and create appropriate secondary indexes on the frequently accessed columns.. Creating secondary indexes on frequently queried columns and partitioning the large table are the most effective actions to improve query performance in SAP HANA. Indexes reduce scan times, while partitioning enables parallel processing and better data management. Together, they address the root cause of slow SELECT statements without unnecessary hardware scaling.

Answer

Implement SAP HANA table replication to a secondary instance for read offloading.

Answer

Enable SAP HANA dynamic tiering to offload cold data to disk.

Answer

Increase the size of the SAP HANA instance to a larger EC2 instance type with more memory.

Question 3

A company is planning to migrate its SAP NetWeaver Application Server ABAP system to AWS. The system currently runs on physical servers on-premises. The company wants to reduce the migration time and effort by using AWS Application Migration Service (AWS MGN). Which statement is true regarding the use of AWS MGN for this SAP system?

Accepted Answer

AWS MGN can replicate the SAP system to AWS and automatically convert it to run on Amazon EC2 instances, supporting both Linux and Windows.. AWS Application Migration Service (AWS MGN) is designed to simplify and expedite server migrations to AWS by replicating source servers and automatically converting them to run on EC2. It supports both Linux and Windows, making it suitable for SAP NetWeaver ABAP systems. It does not require specific virtualization platforms and can handle physical servers, aligning with the company's on-premises setup.

Answer

AWS MGN only supports migration of databases, not application servers, so it cannot be used for SAP NetWeaver.

Answer

AWS MGN cannot be used for SAP systems because SAP does not support migrations to AWS using replication tools.

Answer

AWS MGN requires the source servers to be running on VMware vSphere or Microsoft Hyper-V.

Question 4

A company is running SAP S/4HANA on AWS and wants to reduce the total cost of ownership by using Amazon EC2 Auto Scaling for the SAP application servers. The application servers are stateless and can be terminated at any time. The company uses an Application Load Balancer (ALB) to distribute traffic. Which configuration should the SAP administrator use to ensure that the SAP application servers can be automatically scaled based on CPU utilization?

Accepted Answer

Create a launch template with the SAP application server AMI, create an Auto Scaling group with a target tracking scaling policy based on average CPU utilization, and register the Auto Scaling group with the ALB target group.. A launch template defines the instance configuration, and an Auto Scaling group with a target tracking scaling policy automatically adjusts capacity to maintain a target CPU utilization. Registering the group with the ALB target group ensures that traffic is distributed and health checks are performed. This is the most efficient and recommended approach for stateless SAP application servers.

Answer

Configure a step scaling policy that adds or removes instances based on Amazon CloudWatch alarms for CPU utilization, and use an Amazon EC2 Auto Scaling group with a launch configuration.

Answer

Use AWS Systems Manager Automation to run a runbook that starts or stops EC2 instances based on CPU utilization, and attach a scheduled scaling policy to the Auto Scaling group.

Answer

Create an Auto Scaling group with a simple scaling policy that scales based on CPU utilization, and use an Application Load Balancer to distribute traffic without registering the Auto Scaling group with a target group.

Question 5

A company is deploying SAP S/4HANA on AWS and needs to ensure that the SAP HANA database meets the SAP certification requirements for storage performance. Which AWS storage option should be used for the SAP HANA data and log volumes?

Accepted Answer

Amazon EBS io1 or io2 volumes. SAP HANA requires storage with consistent high IOPS and low latency, which is provided by Amazon EBS Provisioned IOPS SSD volumes (io1/io2). These volumes are certified by SAP for HANA and are the recommended choice for data and log volumes. Other storage options lack the necessary performance characteristics.

Answer

Amazon S3 Standard

Answer

Amazon EFS General Purpose

Answer

Amazon EBS gp2 volumes

Question 6

A company runs its SAP NetWeaver ABAP application servers on Amazon EC2 instances in a private subnet. The SAP HANA database resides on a separate EC2 instance in the same VPC. The company needs to ensure that the SAP application servers can resolve the HANA database hostname and that the database is not accessible from the internet. Which combination of AWS services should be used to meet these requirements with the LEAST operational overhead?

Accepted Answer

Use Amazon Route 53 private hosted zone for internal DNS resolution and a security group that allows traffic only from the application server security group.. The SAP application servers need to resolve the HANA hostname privately, and the database must remain inaccessible from the internet. A Route 53 private hosted zone provides DNS resolution scoped to the VPC, while a security group referencing the application server security group enforces instance-level access control. This native integration avoids public exposure and custom DNS infrastructure, meeting both requirements with minimal management effort.

Answer

Use an Application Load Balancer to distribute traffic to the HANA database and a network ACL to restrict access to the private subnet.

Answer

Deploy a self-managed BIND DNS server on a dedicated EC2 instance and use AWS Network Firewall to filter traffic between subnets.

Answer

Assign Elastic IP addresses to the EC2 instances and use a public Route 53 hosted zone with restrictive security groups.

Question 7

A company runs an SAP HANA database on AWS. The operations team needs to monitor the database for performance issues and receive alerts when certain thresholds are exceeded. They want to use AWS native services to collect and analyze SAP HANA metrics. Which AWS service should be used to collect custom metrics from SAP HANA and trigger alarms?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch is the AWS service designed for monitoring and observability. It can collect custom metrics from SAP HANA using the CloudWatch agent or by publishing metrics via the AWS CLI/SDK. You can then set alarms on these metrics to alert when thresholds are breached. This provides a native AWS solution for monitoring SAP HANA and integrating with other AWS services for automated responses.

Question 8

A company is running an SAP S/4HANA system on AWS with a single SAP HANA database on an EC2 instance. The database uses EBS volumes for data and log. The company needs to implement a backup strategy that allows them to restore the database to any point in time within the last 7 days. Which combination of AWS services and features should be used to achieve this?

Accepted Answer

SAP HANA backup and recovery with continuous log backups to Amazon S3. SAP HANA point-in-time recovery requires continuous log backups in addition to data backups. By configuring SAP HANA to back up logs to Amazon S3, you can restore to any point in time within the retention period. This is the standard SAP approach and is supported on AWS. Other options either do not provide PITR or are not applicable to SAP HANA.

Answer

AWS Storage Gateway with continuous replication to Amazon S3

Answer

Amazon RDS for SAP HANA with automated backups and point-in-time recovery

Answer

AWS Backup with EBS snapshots taken every hour, retained for 7 days

Question 9

A company is deploying SAP S/4HANA on AWS using a scale-out SAP HANA database with three worker nodes and one standby node. The database must be able to fail over automatically if a worker node becomes unavailable. Which AWS service or feature should be used to manage the cluster and automate the failover?

Accepted Answer

SUSE Linux Enterprise High Availability Extension. For SAP HANA scale-out on AWS, automatic failover requires a supported cluster manager that integrates with SAP HANA system replication. SUSE Linux Enterprise High Availability Extension provides the Pacemaker cluster, SAPHanaSR resource agents, and fencing needed to detect a failed worker and promote the standby node. Other AWS services do not provide the HANA-aware cluster resource management required for this scenario.

Question 10

A company runs SAP NetWeaver on Amazon EC2 instances in a single AWS account. The operations team needs to receive an alert when the CPU utilization of a production SAP application server exceeds 80% for 10 minutes. They want a fully managed AWS service that can trigger an Amazon SNS notification. Which service should they use to create the alarm?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch is the appropriate service because it collects EC2 metrics and supports alarms with threshold and time-period conditions. An alarm can be set to trigger when CPU utilization is greater than 80% for 10 minutes and publish to an SNS topic for notification. The other services either log API activity, provide best-practice recommendations, or report AWS service health, none of which can monitor and alarm on customer resource CPU metrics.

Question 11

A company is deploying an SAP NetWeaver application server on AWS. The application server must access a shared file system for /sapmnt and must be able to survive the failure of a single Availability Zone. The company wants to use a managed AWS service to reduce administrative effort. Which solution should be used?

Accepted Answer

Deploy an Amazon EFS file system with mount targets in multiple Availability Zones and mount it from the SAP application servers by using NFS.. Amazon EFS is a managed NFS file system that supports mount targets in multiple Availability Zones, so it remains accessible if one AZ fails. It can be mounted by Linux-based SAP NetWeaver application servers for /sapmnt, and AWS handles the underlying file system management. This meets the shared file system and AZ-resilience requirements with less administrative effort than self-managed options.

Answer

Create an Amazon EBS volume in one Availability Zone and attach it to all application server instances in the Auto Scaling group.

Answer

Deploy an AWS Storage Gateway file gateway in each Availability Zone and present an NFS share to the SAP application servers.

Answer

Deploy an Amazon FSx for Windows File Server file system in a Multi-AZ configuration and mount it from the SAP application servers by using SMB.

Question 12

A company is running an SAP NetWeaver application server on AWS. The application server uses a shared file system for SAP transport directory and global files. The company wants to use a fully managed, scalable, and highly available file system that supports the SMB protocol for Windows-based SAP application servers. Which AWS service should they use?

Accepted Answer

Amazon FSx for Windows File Server.. For Windows-based SAP application servers requiring SMB, Amazon FSx for Windows File Server is the appropriate choice. It is fully managed, supports SMB, integrates with Active Directory, and provides high availability and scalability. It is specifically designed for Windows workloads and is recommended for SAP NetWeaver shared file systems. Other options either do not support SMB natively or are not optimized for this use case.

Answer

Answer

Amazon S3 with SMB gateway.

Answer

Amazon FSx for Lustre.

Question 13

A company runs SAP S/4HANA on AWS and uses an Amazon Route 53 private hosted zone for internal DNS resolution. The SAP application servers must resolve the SAP HANA database hostname to its private IP address. The company also wants to implement a disaster recovery (DR) strategy where the HANA database can be failed over to a secondary instance in another Availability Zone, and the DNS record should automatically point to the new primary. Which Route 53 configuration should be used?

Accepted Answer

Create a Route 53 failover routing policy with a primary record pointing to the current HANA instance and a secondary record pointing to the DR instance, both with health checks.. Route 53 failover routing is designed for active-passive DR scenarios. By configuring a primary record with a health check and a secondary record, Route 53 automatically redirects DNS queries to the secondary when the primary is unhealthy. This ensures SAP application servers reconnect to the DR HANA instance without manual DNS changes, providing seamless failover.

Answer

Create a Route 53 simple routing policy with a single record containing both HANA instance IP addresses, and rely on the client to choose.

Answer

Create a Route 53 latency-based routing policy with records for both HANA instances, and use health checks to remove unhealthy records.

Answer

Create a Route 53 weighted routing policy with equal weights for both HANA instances, and rely on the application to retry on failure.

Question 14

A company is migrating an SAP NetWeaver ABAP system from on-premises to AWS. The system uses a central instance and a separate database instance. The company wants to minimize the cost of the migration by using the existing SAP licenses and avoiding additional SAP software costs. Which migration method should they use?

Accepted Answer

Perform a homogeneous system copy of the SAP system to AWS, keeping the same SAP SID and database platform.. A homogeneous system copy preserves the SAP SID and database platform, allowing the company to reuse existing SAP licenses without additional costs. Other methods either require new licenses, involve reinstallation, or incorrectly assume that AWS services handle SAP licensing.

Answer

Reinstall the SAP system from scratch on AWS and request new SAP license keys from SAP.

Answer

Perform a heterogeneous system copy with a database migration to SAP HANA, which requires new SAP HANA licenses.

Answer

Use AWS Application Migration Service (MGN) to replicate the SAP servers to AWS, which automatically transfers SAP licenses to AWS.

Question 15

A company runs SAP S/4HANA on an Amazon EC2 instance. The operations team wants to be proactively notified whenever the average CPU utilization of the instance exceeds 85% for 10 consecutive minutes, and they need the notification delivered to an email address. The monitoring solution must use native AWS services and require minimal administrative overhead. Which combination of AWS services should be used to meet these requirements?

Accepted Answer

Amazon CloudWatch with a CPU utilization alarm that publishes to an Amazon SNS topic with an email subscription.. Amazon CloudWatch is the AWS-native service for collecting and monitoring EC2 metrics. A CloudWatch alarm can evaluate CPU utilization over a specified period and trigger an action when the threshold is crossed. Publishing to Amazon SNS with an email subscription provides immediate notification. This combination requires no agents or custom code for basic EC2 metrics, meeting the minimal-overhead requirement.

Answer

Amazon Inspector with a continuous assessment template, and an Amazon SNS topic with an email subscription for findings.

Answer

AWS Config with a custom rule that evaluates CPU utilization, and an Amazon EventBridge rule that invokes an AWS Lambda function to send an email.

Answer

AWS CloudTrail with a trail that delivers logs to an Amazon S3 bucket, and an S3 event notification that sends an email via Amazon SES.

Question 16

A company runs SAP NetWeaver ABAP on a single AWS account with EC2 instances across two Availability Zones. The operations team must receive an alert whenever the CPU utilization of any EC2 instance tagged with the key "SAPSystem" and value "PRD" exceeds 85% for five consecutive minutes. Which AWS service should be used to detect this condition and trigger the notification?

Accepted Answer

Amazon CloudWatch. The requirement is a performance-metric threshold with a sustained duration and a notification action. Amazon CloudWatch metric alarms evaluate EC2 metrics such as CPUUtilization over configurable periods, support tag-based scoping, and integrate with Amazon SNS for alerting. The other services handle auditing, best-practice checks, or configuration compliance, none of which can evaluate live CPU utilization against an 85% threshold.

Question 18

A company runs SAP Business Suite on AWS with an Oracle database on an Amazon EC2 instance. The database is experiencing high I/O latency during peak load. The EC2 instance is an r5.4xlarge with two 1 TB gp2 EBS volumes in a RAID 0 configuration. The company wants to improve I/O performance without changing the instance type. Which action should be taken?

Accepted Answer

Replace the gp2 volumes with io1 volumes with a high provisioned IOPS value.. Provisioned IOPS volumes (io1/io2) allow you to specify a consistent IOPS level independent of volume size, which is ideal for I/O-intensive databases like Oracle. gp2 volumes may not provide sufficient baseline IOPS for peak loads. Other options do not directly address the IOPS bottleneck.

Answer

Change the RAID configuration from RAID 0 to RAID 1.

Answer

Enable EBS optimization on the EC2 instance.

Answer

Increase the size of the gp2 volumes to 2 TB each.

Question 19

A company is planning to migrate its SAP NetWeaver ABAP stack to AWS. The SAP system currently runs on AIX with Oracle Database. The company wants to move to a Linux-based environment on Amazon EC2 and use SAP HANA as the new database. They need to perform the migration with minimal downtime and ensure that the SAP system is fully supported on AWS. Which migration method should they use?

Accepted Answer

Use SAP Database Migration Option (DMO) with the Software Update Manager (SUM) to migrate to SAP HANA on AWS.. SAP DMO with SUM is the standard tool for migrating SAP systems to SAP HANA while changing the operating system and database. It performs the migration in a single step, minimizing downtime and ensuring the target system is supported on AWS. It is specifically designed for this scenario and is widely used for SAP migrations to AWS.

Answer

Use AWS Application Migration Service (AWS MGN) to lift and shift the SAP system to EC2, then perform a database migration to SAP HANA.

Answer

Answer

Use SAP HANA System Replication to replicate from Oracle to SAP HANA on AWS.

Question 20

An SAP Basis administrator is designing a high availability solution for an SAP NetWeaver ABAP stack on AWS. The solution must automatically recover from an EC2 instance failure in the primary Availability Zone and ensure that the SAP Central Services (SCS) instance is highly available. Which combination of AWS services and configurations should be used?

Accepted Answer

Configure an overlay IP address and a cluster with Pacemaker and Corosync on two EC2 instances in different Availability Zones, using a secondary private IP address that can be moved between instances.. The recommended high availability design for SAP SCS on AWS uses a Pacemaker and Corosync cluster with an overlay IP address across two Availability Zones. This allows automatic failover of the SCS instance and its virtual IP, ensuring continuous availability. Other options either do not support stateful failover or do not provide the required automation.

Answer

Use an Auto Scaling group with a launch configuration that includes the SCS instance, and place the SCS instance behind an Application Load Balancer.

Answer

Deploy the SCS instance on a single EC2 instance with an Elastic IP address, and use Amazon Route 53 health checks to fail over to a standby instance in another Availability Zone.

Answer

Use AWS Elastic Disaster Recovery to replicate the SCS instance to another Region, and configure automatic failover with a recovery time objective (RTO) of 15 minutes.
