PAS-C01 Practice Exam 61 — 20 Questions

Question 1

A company is migrating its SAP Solution Manager 7.2 system to AWS. The system uses an Oracle database and runs on IBM AIX on-premises. The migration team wants to move to a Linux-based Amazon EC2 instance with SAP HANA as the new database. Which migration method should the team use?

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

Accepted Answer

Heterogeneous system copy with database migration using SAP Software Provisioning Manager (SWPM) and the SAP HANA migration option.. A heterogeneous system copy with database migration using SWPM and the SAP HANA migration option is the correct method because it supports changing both the operating system and the database in a single process. This approach is specifically designed for migrations from non-HANA databases to SAP HANA on a different OS, such as from Oracle on AIX to SAP HANA on Linux.

Answer

Perform a database-level migration using Oracle Data Pump to export data to Amazon S3, then import into SAP HANA using SAP HANA tools.

Answer

Use AWS Application Migration Service (MGN) to replicate the AIX server to EC2 and then change the database.

Answer

Homogeneous system copy using SWPM with the same database type, then upgrade to SAP HANA.

Question 2

A company is migrating an SAP ERP Central Component system with an Oracle database to AWS. The database is 8 TB and the business requires a cutover window of no more than 6 hours. The team plans to use Oracle Data Guard in maximum performance mode to replicate to an Amazon RDS for Oracle target, then perform a switchover. The network link between on-premises and AWS supports 1 Gbps. Which consideration most affects whether the 6-hour cutover window can be met?

Accepted Answer

RDS for Oracle does not support Oracle Data Guard, so the replication design must be replaced with a physical standby on Amazon EC2 before cutover.. The decisive constraint is that Amazon RDS for Oracle does not allow the privileged configuration that Oracle Data Guard requires, so a Data Guard standby cannot be hosted on RDS. The team should run the Oracle standby on Amazon EC2, where SYSDBA control is available, or choose another replication approach. WAN replication and link capacity are manageable through seeding and maximum performance mode, and DB identity is not the fundamental blocker.

Answer

Oracle Data Guard maximum performance mode cannot be used across a WAN link and must be replaced with maximum availability mode.

Answer

Oracle Data Guard switchover requires the target database to use the same DB name and DBID as the source, which is not possible on RDS for Oracle.

Answer

A 1 Gbps link is insufficient to replicate an 8 TB database in the initial synchronization, so the cutover window cannot be met regardless of tooling.

Question 3

A company is planning to deploy a new SAP S/4HANA system on AWS. The company wants to minimize the risk of data loss in case of a failure and needs a recovery point objective (RPO) of less than 1 minute. The system will use an SAP HANA database. Which AWS service should be used to achieve this RPO for the HANA database?

Accepted Answer

SAP HANA System Replication with synchronous mode to a secondary instance in another Availability Zone.. SAP HANA System Replication in synchronous mode provides continuous replication with an RPO of zero, ensuring that no data is lost in case of a failure. This meets the requirement of an RPO of less than 1 minute. Other options either do not provide continuous replication, are not applicable to HANA, or do not exist as described.

Answer

Amazon S3 Cross-Region Replication for the HANA data and log files stored in S3.

Answer

AWS Backup with a backup plan that runs every 5 minutes.

Answer

Amazon RDS for SAP HANA with Multi-AZ deployment.

Question 4

A company is running SAP NetWeaver on AWS with multiple application servers and a central SAP HANA database. The company needs to ensure that the SAP application servers can automatically discover and connect to the database after a failover. Which AWS service should be used to manage the database connection endpoint?

Accepted Answer

An overlay IP address managed by a cluster manager such as SUSE Linux Enterprise High Availability Extension or Red Hat Enterprise Linux High Availability Add-On.. In SAP on AWS high-availability architectures, a cluster manager (such as SUSE Linux Enterprise High Availability Extension or Red Hat Enterprise Linux High Availability Add-On) manages an overlay IP address that is associated with the active database instance. SAP application servers connect to this virtual IP, so when a failover occurs, the IP moves to the new primary, and the application servers automatically reconnect without manual reconfiguration. This is the standard and recommended approach.

Answer

AWS Global Accelerator with an endpoint group for the database instances.

Answer

Amazon Route 53 with a private hosted zone and a CNAME record pointing to the active database instance.

Answer

AWS Cloud Map

Question 5

A company runs SAP NetWeaver on AWS and uses Amazon CloudWatch for monitoring. The operations team wants to receive alerts when the SAP application server's CPU utilization exceeds 80% for 10 minutes. They also want to automatically restart the application server if it becomes unresponsive. Which two actions should they take to meet these requirements? (Choose two.)

Accepted Answer

Create a CloudWatch alarm on the CPUUtilization metric with a threshold of 80% for 10 minutes and configure an Amazon SNS topic to notify the operations team.. To alert on CPU utilization, create a CloudWatch alarm with the specified threshold and duration, and use SNS for notifications. To automatically restart an unresponsive server, use Systems Manager Automation triggered by the alarm. These two actions together provide both alerting and remediation, meeting the requirements.

Answer

Configure AWS CloudTrail to log all API calls and create a CloudWatch alarm based on the StopInstances API call to detect unresponsive servers.

Answer

Use AWS Config to monitor the EC2 instance's configuration and trigger an AWS Lambda function to restart the instance when the configuration changes.

Answer

Enable detailed monitoring on the EC2 instance to get 1-minute metrics and create a CloudWatch alarm with a threshold of 80% for 5 minutes.

Question 6

A company runs an SAP S/4HANA system on AWS with the application servers on Amazon EC2 instances and the SAP HANA database on a separate EC2 instance. Users report intermittent slow response times during month-end processing. Amazon CloudWatch metrics show that the application server instances have high CPU utilization but low network throughput, and the SAP HANA database has low CPU utilization. The SAP Basis team wants to improve performance without over-provisioning. Which action should they take?

Accepted Answer

Increase the size of the application server EC2 instances to a larger instance type with more vCPUs.. The performance data points to the application servers as the bottleneck because they have high CPU utilization while the database has low CPU utilization. Scaling up the application server instances provides additional compute resources to handle the increased processing demand during month-end closing. This approach is more effective than changing network settings, database resources, or load balancing, which do not address the CPU constraint on the application layer.

Answer

Migrate the SAP HANA database to a larger EC2 instance type with more memory.

Answer

Configure an Application Load Balancer to distribute traffic across multiple application server instances.

Answer

Enable enhanced networking with the Elastic Network Adapter (ENA) on the application server instances.

Question 7

A company operates SAP S/4HANA on AWS with SAP HANA System Replication between two Availability Zones. During a planned operating system patching window, the administrator must patch the secondary HANA host and then the primary host while keeping the replication relationship healthy. Which sequence of operations should the administrator perform?

Accepted Answer

Patch the secondary host while replication is active, then perform a takeover so the secondary becomes primary, patch the former primary, and re-register it as the new secondary.. Rolling maintenance in an SAP HANA System Replication landscape always begins with the node that is not serving production traffic. Patching the standby, taking over so it becomes primary, patching the former primary, and then re-registering it as the new standby preserves a live production node throughout and keeps the replication relationship correctly oriented after the window.

Answer

Stop both HANA instances, patch both hosts, restart the primary, and let SAP HANA System Replication automatically resynchronize the secondary in delta mode.

Answer

Patch the primary host first, then perform a takeover on the secondary, and finally re-register the original primary as the new secondary.

Answer

Suspend SAP HANA System Replication, patch both hosts, then resume replication and run a full data backup on the primary.

Question 8

A company is deploying SAP HANA on AWS using a scale-out architecture with multiple EC2 instances. The company needs to ensure that the HANA database can automatically recover from an Availability Zone failure with minimal data loss and downtime. Which combination of AWS services and configurations should be used?

Accepted Answer

Use SAP HANA system replication with a secondary site in another Availability Zone, and configure an overlay IP address with a cluster manager like Pacemaker.. SAP HANA system replication with a secondary site in another Availability Zone, combined with a cluster manager like Pacemaker for overlay IP management, is the standard high availability solution on AWS. It provides automatic failover and minimal data loss, meeting the requirements for scale-out deployments.

Answer

Use Amazon S3 for HANA data storage and AWS Lambda for automatic failover.

Answer

Deploy HANA scale-out across multiple Availability Zones using Amazon EC2 Auto Scaling and an Application Load Balancer.

Answer

Deploy HANA on a single EC2 instance with a large instance size and use EBS snapshots for recovery.

Question 9

A company is planning to migrate its SAP Business Suite on anyDB to AWS. The migration team wants to use an AWS service that automates the replication of the database to Amazon EC2 while allowing them to choose the target database engine. Which AWS service should they use?

Accepted Answer

AWS Database Migration Service (AWS DMS). AWS Database Migration Service (AWS DMS) is specifically built for database migrations, supporting both homogeneous and heterogeneous moves. It replicates data continuously and allows the target database engine to be different from the source, which is ideal for SAP Business Suite on anyDB migrations.

Question 11

A company is deploying a new SAP application on AWS. They want to ensure the Amazon EC2 instances used for the SAP application servers are optimally configured for SAP. Which action should they take?

Accepted Answer

Select an instance type that is certified by SAP for the specific SAP application and workload.. SAP and AWS jointly certify specific EC2 instance types for SAP applications. Using a certified instance type ensures that the instance meets SAP's performance and compatibility requirements, and that it is supported by both vendors. This is the most direct way to ensure the instances are optimally configured for the SAP application, as opposed to using general-purpose types, monitoring, or cost-saving measures that do not address suitability.

Answer

Enable detailed monitoring in Amazon CloudWatch for all instances.

Answer

Use Spot Instances for all SAP application servers to reduce cost.

Answer

Use a general-purpose instance type like M5 for all SAP application servers.

Question 12

A company runs SAP S/4HANA on AWS with an SAP HANA database on an EC2 instance. The database is using Amazon EBS io2 volumes for data and log. The company wants to implement a disaster recovery (DR) solution that provides a recovery point objective (RPO) of less than 5 minutes and a recovery time objective (RTO) of less than 30 minutes. The DR site must be in a different AWS Region. Which solution should be implemented to meet these requirements?

Accepted Answer

Configure SAP HANA system replication (HSR) to a secondary HANA instance in the DR Region, with asynchronous replication mode, and use AWS Global Accelerator for network acceleration.. The correct answer is to configure SAP HANA system replication (HSR) to a secondary instance in the DR Region with asynchronous replication. HSR is the native SAP solution for HANA DR and can meet the RPO and RTO requirements. AWS Global Accelerator improves network performance between Regions. Other options either do not meet the RPO/RTO or are not application-consistent for HANA.

Answer

Use AWS Elastic Disaster Recovery (DRS) to replicate the EC2 instance and EBS volumes to the DR Region, and perform a failover when needed.

Answer

Use Amazon S3 cross-region replication to copy SAP HANA backups to the DR Region, and restore the database from backups in the event of a disaster.

Answer

Use Amazon EBS snapshots with cross-region copy to replicate the HANA data and log volumes to the DR Region, and create new EBS volumes from snapshots during a disaster.

A company is migrating its SAP NetWeaver ABAP stack to AWS using a homogeneous system copy. The source system runs on an on-premises server with HP-UX and an Oracle database. The target will use Amazon EC2 with SUSE Linux and SAP HANA. The migration team must determine the appropriate method. Which migration approach should they use?

Accepted Answer

Perform a heterogeneous system copy using the SAP Software Provisioning Manager with the 'Target Database' option set to SAP HANA.. The migration involves changing both the operating system (HP-UX to Linux) and the database (Oracle to SAP HANA). This qualifies as a heterogeneous system copy, which SAP supports through Software Provisioning Manager. The tool handles the data conversion and platform-specific adjustments required for SAP HANA on AWS. Other options either do not support the required changes or are not SAP-recommended.

Answer

Export the SAP system using SAP data extraction tools, create a new SAP system on AWS with SAP HANA, and manually reapply all customizations and data.

Answer

Perform a homogeneous system copy using a backup and restore of the Oracle database, then convert the database to SAP HANA using the SAP HANA database migration option.

Answer

Use AWS Application Migration Service (MGN) to replicate the on-premises server to AWS, then change the operating system and database in place.

Question 15

A company is migrating an SAP NetWeaver system to AWS. The system consists of a central services instance, multiple application servers, and a database. The company wants to ensure that the application servers can be automatically replaced if they fail, and that the system can scale out during peak periods. Which AWS service should a solutions architect use to meet these requirements?

Question 16

A company is migrating its SAP S/4HANA system to AWS. The system uses SAP HANA 2.0 SPS05 and runs on a scale-up architecture. The company wants to use Amazon EC2 instances with SAP HANA certified hardware. They need to ensure that the instance type supports the required memory and that the storage configuration meets SAP's performance requirements for the HANA database. Which combination of EC2 instance family and storage type should they use?

Accepted Answer

Use an X1e instance with Amazon EBS io1 volumes with provisioned IOPS for data and log.. SAP HANA on AWS requires memory-optimized EC2 instances certified by SAP, such as X1e or High Memory instances. For storage, provisioned IOPS volumes like io1 or io2 are necessary to meet the low-latency, high-IOPS demands of HANA. Using general-purpose instances or throughput-optimized HDD volumes would not meet performance requirements and could violate SAP support agreements.

Answer

Use an X1e instance with Amazon EBS gp2 volumes for data and log.

Answer

Use an X1e instance with Amazon EBS st1 volumes for data and log.

Answer

Use an M5 instance with Amazon EBS io1 volumes with provisioned IOPS for data and log.

Question 17

A company runs SAP NetWeaver on AWS and wants to reduce the cost of the SAP application servers during non-business hours. The application servers are currently running 24/7 on EC2 instances. The company requires that the SAP system be automatically started and stopped on a schedule, and that the SAP application servers be gracefully shut down to avoid data corruption. Which solution should be implemented?

Accepted Answer

Use AWS Systems Manager Automation with a maintenance window to run a script that calls SAP start/stop commands on the instances.. To automatically start and stop SAP application servers on a schedule while ensuring graceful shutdown, AWS Systems Manager Automation with a maintenance window is the appropriate solution. It can run SAP-specific start/stop commands on the instances, preserving data integrity. Other options either do not gracefully shut down SAP or are not schedule-based.

Answer

Use AWS Lambda to stop the EC2 instances directly via the StopInstances API call at night and start them in the morning.

Answer

Create an Auto Scaling group with a scheduled scaling policy to terminate instances at night and launch new ones in the morning.

Answer

Configure an Amazon CloudWatch alarm to trigger an AWS Lambda function that stops the instances when CPU utilization is low.

Question 18

A company is deploying SAP S/4HANA on AWS and needs to ensure that the SAP HANA database can be backed up to Amazon S3 without storing AWS credentials on the EC2 instance. The backup must be encrypted at rest. Which combination of steps should the company take?

Accepted Answer

Attach an IAM role to the EC2 instance with permissions to the S3 bucket and enable S3 default encryption.. The most secure and operationally sound method is to attach an IAM role to the EC2 instance, which provides temporary credentials to the SAP HANA backup process. The SAP HANA backint agent can use these credentials to write directly to S3. Enabling default encryption on the S3 bucket ensures that all backup objects are encrypted at rest. This avoids storing long-term AWS credentials on the instance.

Answer

Configure SAP HANA to write backups to an Amazon EBS volume and use AWS Backup to copy to S3 with encryption.

Answer

Use AWS Storage Gateway to back up SAP HANA to S3 and enable S3 default encryption.

Answer

Store AWS access keys in an SAP HANA secure store and enable default encryption on the S3 bucket.

Question 19

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as the database and runs on SUSE Linux Enterprise Server. The migration team wants to ensure that the SAP HANA database is highly available across two Availability Zones. Which two configurations should be used to achieve this? (Choose two.)

Accepted Answer

Deploy SAP HANA with synchronous replication to a secondary instance in a different Availability Zone using SAP HANA System Replication.. To achieve high availability for SAP HANA across two Availability Zones on AWS, you should use SAP HANA System Replication in synchronous mode to replicate data to a secondary instance in a different Availability Zone, and configure an overlay IP with a cluster manager like Pacemaker to manage failover and client connectivity. These two configurations together provide zero data loss and automated failover.

Answer

Use Amazon S3 Cross-Region Replication to replicate the HANA data and log backups to another region.

Answer

Use an Amazon Route 53 latency-based routing policy to distribute traffic between the two HANA instances.

Answer

Deploy both HANA instances in the same Availability Zone to reduce network latency.

Question 20

A company is deploying a new SAP HANA database on an Amazon EC2 instance. The company needs to ensure that the storage configuration provides the required IOPS and throughput for the database. The chosen instance type is r5.8xlarge. Which storage configuration should the company use to meet SAP HANA performance requirements?

Accepted Answer

Use multiple io1 EBS volumes in a RAID 0 configuration for data and separate io1 volumes for log.. SAP HANA requires high IOPS and low latency for data and log files. Provisioned IOPS io1 volumes allow independent provisioning of IOPS, and RAID 0 aggregates multiple volumes to achieve the required performance. Separating data and log onto different volumes prevents I/O contention, which is a best practice for SAP HANA on AWS.

Answer

Use a single gp2 EBS volume for all SAP HANA data and log files.

Answer

Use a single st1 throughput-optimized HDD volume for all SAP HANA files.

Answer

Use Amazon S3 for SAP HANA data and log storage, mounted via AWS Storage Gateway.
