PAS-C01 Practice Exam 55 — 20 Questions

Question 1

An SAP administrator runs the AWS CLI command shown in the exhibit. The SAP HANA instance is running on an r5.4xlarge in us-east-1a. The administrator wants to change the instance type to r5.8xlarge to improve performance. What must the administrator do first?

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

Accepted Answer

Stop the instance from the AWS Management Console.. To change the instance type of an EC2 instance, the instance must first be stopped. While stopped, you can modify the instance type via the AWS Management Console, CLI, or SDK. After the instance is stopped, the administrator can change the type from r5.4xlarge to r5.8xlarge and then start the instance again.

Answer

Create an AMI of the instance and launch a new instance with the larger type.

Answer

Detach the EBS volumes and attach them to a new instance.

Answer

Modify the instance type in the instance settings while it is running.

Question 2

An SAP system on AWS is experiencing performance degradation. The SAP administrator wants to monitor the EC2 instance's CPU utilization and memory usage. Which AWS service should be used to collect memory metrics?

Accepted Answer

Amazon CloudWatch Agent. Amazon CloudWatch by default collects only basic metrics like CPU utilization, not memory usage. The Amazon CloudWatch Agent is required to collect custom metrics such as memory utilization from EC2 instances by sending data to CloudWatch via the PutMetricData API. This agent can be installed on the SAP EC2 instance to capture both CPU and memory metrics for performance monitoring.

Answer

Amazon CloudWatch (default metrics)

Answer

AWS Systems Manager Inventory

Answer

AWS Trusted Advisor

Question 3

Which THREE of the following are valid methods to automate the installation of SAP HANA on AWS? (Choose three.)

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP (Option B) is a valid method to automate SAP HANA installation because it provides a guided, automated deployment experience that collects input for infrastructure sizing, configuration, and software installation, then orchestrates the provisioning of AWS resources and the SAP HANA software setup. It reduces manual effort by automating the deployment of SAP HANA on AWS, making it a correct choice for this question.

Answer

AWS Systems Manager Automation

Answer

AWS OpsWorks

Question 4

A company runs its SAP system on AWS and uses a Multi-AZ RDS for Oracle database for the SAP Central Services (SCS) instance. The SCS instance is currently on a single EC2 instance in one Availability Zone. The company wants to ensure high availability for the SCS service. What should they do?

Accepted Answer

Implement an SAP ASCS/ERS cluster using two EC2 instances and a shared file system.. SAP Central Services (SCS) can be made highly available by implementing an SAP ASCS/ERS cluster using two EC2 instances and a shared file system (such as Amazon FSx for Windows or EBS Multi-Attach) with a floating IP. This provides automatic failover in case of instance or AZ failure. Option B is incorrect because placing the SCS on a larger EC2 instance with EBS snapshots does not provide high availability; it only offers data backup and recovery, not automatic failover. Option C is incorrect because an Application Load Balancer is designed for HTTP/HTTPS traffic and cannot handle SAP-specific protocols used by SCS. Option D is incorrect because the RDS for Oracle database is used for the SAP database, not for the SCS instance; the SCS requires its own file system and cannot run on RDS.

Answer

Place the SCS instance on a larger EC2 instance and use EBS snapshots for recovery.

Answer

Use an Application Load Balancer to distribute traffic to multiple SCS instances.

Answer

Configure the SCS instance on the existing RDS for Oracle database.

Question 5

The exhibit shows a CloudFormation template snippet. During migration, the SAP application server fails to start because the root volume is too small. What is the most efficient fix?

Accepted Answer

Modify the template to increase VolumeSize to 100 and update the stack.. Modifying the template to increase the volume size and updating the stack is the proper Infrastructure as Code approach. Option A is wrong because modifying the volume directly is not recommended for CloudFormation-managed resources. Option C is wrong because stopping the instance is not necessary for volume modification, but the template should be updated. Option D is wrong because deleting and recreating is less efficient.

Answer

Manually resize the EBS volume via the AWS Console and then update the stack.

Answer

Stop the instance, modify the volume size, and start the instance.

Answer

Delete the stack and create a new one with a larger volume.

Question 6

An SAP system is running on EC2 instances with EBS volumes. The administrator wants to automate the creation of point-in-time snapshots of the EBS volumes for disaster recovery. Which AWS service is best suited for this?

Accepted Answer

Amazon Data Lifecycle Manager (DLM). Amazon Data Lifecycle Manager (DLM) is specifically designed to automate the creation, retention, and deletion of EBS snapshots for backup and disaster recovery. Option A (AWS Backup) can also back up EBS volumes but is a broader service; DLM is more tailored for EBS snapshot lifecycle management. Option B (Amazon S3 Lifecycle policies) manages object lifecycle in S3, not EBS snapshots. Option D (AWS CloudFormation) provisions infrastructure but does not directly automate snapshot creation.

Answer

AWS Backup

Answer

Amazon S3 Lifecycle policies

Answer

AWS CloudFormation

Question 7

A company is migrating its SAP ERP system to AWS using the SAP S/4HANA migration approach. They need to replicate the source system continuously to the target before cutover. Which AWS service should be used for this continuous replication?

Accepted Answer

AWS CloudEndure Migration. AWS CloudEndure Migration provides continuous block-level replication from on-premises servers to AWS, making it suitable for SAP S/4HANA migrations requiring ongoing replication before cutover. AWS SCT (A) is for schema conversion, not replication. AWS SMS (B) migrates entire servers but does not support continuous replication. AWS DMS (C) can replicate databases but has limitations for SAP-specific workloads and is not the recommended service for SAP S/4HANA continuous replication. Therefore, AWS CloudEndure (D) is the correct choice.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (DMS)

Question 8

A company is migrating an SAP HANA database to AWS. The database must be backed up automatically. Which TWO AWS services can be used for this purpose? (Choose 2.)

Accepted Answer

Amazon S3. Amazon S3 is correct because it can be used as a target for SAP HANA backup and recovery using the SAP HANA Backup to S3 feature, which allows direct backup of HANA databases to S3 buckets via the SAP HANA Studio or hdbsql commands. AWS Backup is correct because it provides a fully managed backup service that can automate and centralize backups of SAP HANA databases running on Amazon EC2 instances, using the AWS Backup console or API to create and manage backup policies.

Answer

Amazon RDS

Answer

AWS Database Migration Service

Answer

Amazon EFS

Question 9

An SAP Basis team is troubleshooting a performance issue on an SAP HANA database running on AWS. The HANA index server is consuming high CPU. The team suspects that the underlying EC2 instance is throttled. Which CloudWatch metric should be checked to confirm CPU throttling?

Accepted Answer

CPUCreditBalance. CPUCreditBalance indicates the number of CPU credits available for burstable performance instances. If the credit balance is depleted, the instance is throttled, which can cause high CPU usage with limited performance. Option A (CPUUtilization) shows CPU usage but does not directly indicate throttling. Option B (NetworkIn) and Option D (DiskReadOps) are unrelated to CPU throttling.

Answer

CPUUtilization

Answer

NetworkIn

Answer

DiskReadOps

Question 10

A company wants to implement a backup strategy for SAP HANA on AWS. The backup must be stored securely and be accessible for restore to a different AWS Region. Which combination of AWS services should be used?

Accepted Answer

Use AWS Backup with cross-region backup copy. AWS Backup with cross-region backup copy is the correct choice because it provides a fully managed, policy-driven backup service that natively supports SAP HANA on Amazon EC2, including automated cross-region copy for disaster recovery. This ensures backups are stored securely (encrypted at rest and in transit) and can be restored in a different AWS Region without manual intervention.

Answer

Take EBS snapshots and copy them to another region

Answer

Store HANA backups in Amazon S3 Standard-IA

Answer

Use Amazon S3 Glacier Deep Archive

Question 11

A global company is migrating its SAP ERP system to AWS. The system runs SAP ECC on IBM AIX with Oracle Database. The company plans to move to SAP S/4HANA on AWS. The source system is 5 TB in size. The network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must be completed within a 2-week window with minimal downtime. The company has a SAP license that allows running S/4HANA on certified hardware. They have already used AWS SCT to convert the database schema to SAP HANA-compatible format. They now need to execute the data migration. The team is considering the following options:

Option A: Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover.
Option B: Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA.
Option C: Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA.
Option D: Use SAP HANA system replication from the source Oracle database to the target HANA database.

Which option is the most feasible and efficient for this migration?

Accepted Answer

Use AWS DMS with ongoing replication from Oracle to HANA, then perform a final cutover. The most feasible because AWS DMS supports heterogeneous migrations from Oracle to SAP HANA, and the ongoing replication capability minimizes downtime during the cutover. Option A (SAP HANA system replication) is incorrect because it requires the source database to already be SAP HANA, not Oracle. Option B (Snowball Edge) is inefficient for this scenario because restoring from backup files does not provide ongoing replication, and the 2-week window with minimal downtime would be difficult to achieve. Option C (DataSync to EFS) is designed for file transfers, not database migration, and importing into HANA would require additional complex steps. The schema conversion has already been done with AWS SCT, so DMS can handle the data migration efficiently.

Answer

Use SAP HANA system replication from the source Oracle database to the target HANA database

Answer

Use AWS Snowball Edge to transfer the Oracle backup files to AWS, then restore to HANA

Answer

Use AWS DataSync to copy the Oracle data files to Amazon EFS, then import into HANA

Question 12

An SAP administrator is configuring the /hana/data volume for SAP HANA on an EC2 instance. The exhibit shows the /etc/fstab entry. What is the purpose of the 'noatime' mount option?

Accepted Answer

To disable updating the access time on files, improving performance.. The 'noatime' mount option disables the update of inode access timestamps (atime) on every file read. For SAP HANA, which performs high-frequency I/O operations on the /hana/data volume, this eliminates unnecessary metadata writes, reducing disk I/O overhead and improving overall filesystem performance.

Answer

To enable swap space on the volume.

Answer

To enable disk quotas.

Answer

To mount the volume as read-only.

Question 13

Which TWO AWS services can be used to monitor SAP system performance and send alerts? (Choose two.)

Accepted Answer

Amazon Simple Notification Service (SNS). Amazon CloudWatch is the primary AWS monitoring service that can collect metrics from SAP systems (e.g., via SAP Cloud Connector or custom scripts) and trigger alarms based on thresholds. Amazon SNS is the notification service that CloudWatch alarms use to send alerts via email, SMS, or HTTP endpoints. Together, they form the standard monitoring and alerting pipeline for SAP workloads on AWS.

Answer

Amazon Inspector

Answer

AWS Config

Answer

AWS Trusted Advisor

Question 14

An SAP HANA database is running on a Dedicated Host in us-east-1a. The system requires a disaster recovery site in us-west-2. What limitation does the use of a Dedicated Host impose on the DR setup?

Accepted Answer

The DR site requires a separate Dedicated Host in us-west-2, increasing cost.. A Dedicated Host in us-east-1a is a physical server dedicated to your use, and to set up disaster recovery in us-west-2, you must provision a separate Dedicated Host in that region. This increases costs as you are paying for two Dedicated Hosts instead of one, and the DR host cannot be shared or reserved in advance for a specific instance type without an active allocation.

Answer

The DR site must also use a Dedicated Host, which cannot be reserved in advance.

Answer

The Dedicated Host cannot be used with SAP HANA System Replication.

Answer

The HANA instance cannot be migrated to a different host, so DR is not possible.

Question 15

A company is deploying SAP S/4HANA on AWS and needs to choose instance types that are certified by SAP. Which TWO instance families are SAP-certified for production SAP HANA workloads?

Accepted Answer

R5. The question asks for two certified instance families for production SAP HANA workloads. Among the provided options, only R5 (A) and X1e (C) are SAP-certified for production HANA. T3, M5, and P3 are not certified. Therefore, the correct answers are A and C.

Answer

T3

Answer

M5

Answer

P3

Question 16

A company runs SAP Business Suite on AWS and wants to implement a disaster recovery solution using a pilot light approach. Which THREE components should be pre-provisioned in the DR region to reduce recovery time?

Accepted Answer

Pre-allocated Elastic IP addresses. Pre-allocated Elastic IP addresses (Option C) are correct because in a pilot light DR setup, you need to ensure that the Elastic IPs are reserved in the DR region ahead of time. This allows you to quickly remap them to the recovered EC2 instances during failover, avoiding the delay of requesting new IPs or dealing with IP address conflicts. By pre-provisioning the Elastic IPs, you reduce the time required to restore network connectivity and DNS mappings, which is critical for meeting RTO objectives.

Answer

An Amazon RDS for SAP HANA instance

Answer

Running EC2 instances for all SAP components

Question 17

An SAP system on AWS needs to store sensitive configuration files securely and automatically rotate the encryption keys. Which AWS service should be used?

Accepted Answer

AWS Systems Manager Parameter Store with AWS KMS.. AWS Systems Manager Parameter Store integrated with AWS KMS is the correct choice because it provides a secure, hierarchical store for sensitive configuration data (like SAP configuration files) and supports automatic key rotation via KMS-managed keys. Parameter Store can store encrypted strings using KMS keys, and KMS can be configured to rotate the underlying encryption key automatically every year (or on demand), meeting the requirement for both secure storage and automated key rotation.

Answer

Amazon S3 with server-side encryption.

Answer

AWS Key Management Service (KMS) alone.

Answer

AWS Secrets Manager.

Question 18

A company is migrating a multi-tier application to AWS. The application includes a load balancer, web servers, and an Oracle database. The migration plan includes using AWS DMS for the database. During the initial full load, the DMS task fails with an error indicating insufficient memory. The source database is on an EC2 instance with 4 GB RAM. What should the migration team do to resolve this issue?

Accepted Answer

Increase the size of the DMS replication instance. The error 'insufficient memory' during the initial full load in AWS DMS typically indicates that the replication instance does not have enough memory to handle the data volume or LOB processing. Increasing the size of the DMS replication instance provides more memory for caching, transformation, and LOB handling, directly resolving the resource constraint without altering the source database or task structure.

Answer

Disable LOB support in the DMS task

Answer

Split the migration into multiple smaller tasks

Answer

Increase the memory of the source EC2 instance

Question 19

A company is migrating a legacy monolithic application to a microservices architecture on AWS. The application currently uses an Oracle database with complex stored procedures. The company wants to minimize changes to the application code during migration. Which database migration strategy should the company use?

Accepted Answer

Replatform the application by migrating the Oracle database to Amazon RDS for Oracle. The company wants to minimize changes to the application code during migration. By replatforming the Oracle database to Amazon RDS for Oracle, the application can continue to use the same Oracle database engine, stored procedures, and SQL dialect with minimal or no code changes. This approach avoids the need to rewrite complex stored procedures or adapt to a different database engine, which would be required with other migration strategies.

Answer

Migrate the database to Amazon Aurora with PostgreSQL compatibility using the AWS Database Migration Service (DMS)

Answer

Store the data in Amazon S3 and use Athena for querying

Answer

Refactor the application to use Amazon DynamoDB as the database

Question 20

Which TWO actions should an SAP administrator take to ensure high availability for an SAP HANA database on AWS? (Choose two.)

Accepted Answer

Enable SAP HANA system replication. Options A and D are correct. Enabling SAP HANA system replication provides data redundancy and automatic failover within the same region. Using a Multi-AZ deployment (e.g., with Amazon EBS multi-attach or cluster) ensures the database is available across different Availability Zones, providing automatic failover and high availability. Option B is wrong because a single large instance is a single point of failure. Option C is wrong because manual snapshots are not automatic and do not provide high availability. Option E is wrong because a single EBS volume is a single point of failure and does not provide redundancy.

Answer

Deploy the database on a single large instance

Answer

Schedule regular manual snapshots

Answer

Use a single EBS volume with high IOPS
