PAS-C01 Practice Test 28 — 15 Questions

Question 1

A company is migrating a legacy SAP ECC 6.0 system to SAP S/4HANA on AWS. The current database is IBM Db2. Which AWS service should be used to assess the source system and plan the migration?

Accepted Answer

AWS Migration Evaluator. AWS Migration Evaluator (formerly TSO Logic) is the correct service for assessing the source SAP ECC 6.0 system and planning the migration to SAP S/4HANA. It provides a data-driven business case, including SAP-specific insights such as system sizing, licensing, and total cost of ownership. AWS Application Discovery Service is used for server-level discovery and dependency mapping, not SAP-specific assessment. AWS CloudEndure Migration is for lift-and-shift migration, not assessment. AWS Database Migration Service (DMS) is for migrating databases, not assessment.

Answer

AWS Application Discovery Service

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (DMS)

Question 2

A company is migrating a Windows-based .NET application to AWS. The application currently uses Active Directory for authentication. Which AWS service should they use to maintain a similar authentication experience?

Accepted Answer

AWS Directory Service for Microsoft Active Directory. AWS Directory Service for Microsoft Active Directory provides a managed Microsoft Active Directory in the AWS cloud, allowing the application to authenticate against Active Directory without changes. Option A is correct. Option B (Simple AD) is a Samba-based directory, not fully compatible with all .NET AD features. Option C (IAM) manages access to AWS resources, not application authentication. Option D (Cognito) is for external user pools, not enterprise AD integration.

Answer

AWS Directory Service Simple AD

Answer

AWS Identity and Access Management (IAM)

Answer

Amazon Cognito

Question 3

Which TWO AWS services can be used to migrate an on-premises SAP HANA database to AWS with minimal downtime? (Choose 2.)

Accepted Answer

SAP Landscape Transformation (SLT). (SAP Landscape Transformation) is correct because SLT can replicate data in real-time from an on-premises SAP system to SAP HANA on AWS, enabling minimal downtime migration. Option E (SAP HANA System Replication) is correct because HSR provides native, continuous database replication with automatic failover, allowing migration with minimal downtime. Options B (AWS Backup), C (AWS DMS), and D (CloudEndure) are incorrect: AWS Backup is for backup/restore, not continuous replication; DMS does not support SAP HANA as a source; CloudEndure is not recommended for SAP HANA workloads.

Answer

AWS Backup

Answer

AWS Database Migration Service (DMS)

Answer

AWS CloudEndure Migration

Question 4

A company is migrating an SAP HANA system from on-premises to AWS. The HANA system uses a large amount of memory (2 TB). Which EC2 instance type is most suitable for this workload?

Accepted Answer

x2iedn.32xlarge. (x2iedn.32xlarge) is correct because it is a memory-optimized instance with up to 4 TB of memory, making it suitable for SAP HANA workloads requiring 2 TB of memory. Option B (c5n.18xlarge) is wrong because c5n instances are compute-optimized and have less memory. Option C (m5n.24xlarge) is wrong because m5n instances are general-purpose and cannot support 2 TB of memory. Option D (r5.24xlarge) is wrong because r5 instances have a maximum memory of 768 GB.

Answer

c5n.18xlarge

Answer

m5n.24xlarge

Answer

r5.24xlarge

Question 5

A company is migrating their SAP Business Warehouse (BW) system to AWS. They want to use Amazon S3 for BW near-line storage (NLS). They have set up an S3 bucket and configured the SAP BW NLS connection. However, when they test the connection, it fails. What is the MOST likely cause?

Accepted Answer

Missing AWS Storage Gateway File Gateway setup between SAP and S3. SAP BW near-line storage (NLS) requires an S3-compatible interface. AWS Storage Gateway File Gateway provides a file system interface that SAP can mount and use as NLS, bridging the gap between SAP's NFS-based requirements and Amazon S3 object storage. Option A is incorrect: KMS encryption does not block SAP access; SAP can be configured to access encrypted buckets. Option B is incorrect: S3 bucket names are globally unique, so a name mismatch with region is not possible. Option C is incorrect: Multipart uploads are enabled by default for all S3 buckets and are not a prerequisite for NLS.

Answer

The S3 bucket is encrypted with AWS KMS and SAP cannot access it

Answer

The S3 bucket name does not match the AWS region

Answer

The S3 bucket is not configured for multipart uploads

Question 6

A company is migrating an SAP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS/ERS). Which THREE components are required for a highly available SAP ASCS/ERS setup on AWS? (Choose THREE.)

Accepted Answer

A cluster manager (e.g., Pacemaker). For a highly available SAP ASCS/ERS setup on AWS, three components are required: a cluster manager (e.g., Pacemaker) to manage failover (Option A), a shared file system (e.g., Amazon FSx or EFS) to store the SAP profile and transport directories (Option D), and an Elastic IP address to provide a stable virtual IP that can be moved between EC2 instances during failover (Option E). An Application Load Balancer (Option B) is not used for ASCS/ERS, and Amazon Route 53 health checks (Option C) are optional for DNS-based routing, not a required component.

Answer

An Application Load Balancer

Answer

Amazon Route 53 health checks

Question 7

A company is migrating a critical SAP HANA database to AWS. The database size is 2 TB. They require the highest network throughput and low latency between EC2 instances. Which EC2 placement strategy should they use?

Accepted Answer

Cluster Placement Group. Placement Groups with Cluster Placement provide low latency and high throughput within a single AZ. Option D (Cluster Placement Group) is correct. Option A (Spread Placement Group) is for high availability, not performance. Option B (Partition Placement Group) is for large distributed systems. Option C (Dedicated Hosts) provides licensing benefits, not network performance.

Answer

Spread Placement Group across multiple Availability Zones

Answer

Partition Placement Group

Answer

Dedicated Hosts

Question 8

A company wants to migrate a 10 TB SAP HANA database to AWS with minimal downtime. The network bandwidth between the on-premises data center and AWS is 1 Gbps. Which migration method is most suitable?

Accepted Answer

Use AWS Snowball Edge to transfer the initial data load, then use AWS DMS for ongoing replication.. Given the large data size and limited bandwidth, using AWS Snowball Edge for initial load reduces network dependency. AWS DMS with CDC requires a stable connection but initial load over 1 Gbps would take >22 hours. Backup/restore over network also suffers from bandwidth. SAP HANA System Replication requires high bandwidth and low latency.

Answer

Use SAP HANA System Replication directly over the internet.

Answer

Use AWS DMS with ongoing replication to migrate data incrementally.

Answer

Use AWS Backup to back up the database to S3 and restore to an EC2 instance.

Question 9

A company is migrating a critical SAP system to AWS using the SAP Landscape Virtualization Management (LVM) and AWS Launch Wizard. What is the primary benefit of using AWS Launch Wizard for SAP deployment?

Accepted Answer

It automates the deployment of SAP systems based on AWS best practices. AWS Launch Wizard automates the deployment of SAP systems by providing guided best-practice recommendations, reducing manual effort and errors. Option B is wrong because Launch Wizard is for deployment, not migration; migration requires other tools like AWS Migration Service or SAP LVM. Option C is wrong because Launch Wizard focuses on initial deployment, not ongoing backup and disaster recovery management, though it can integrate with AWS Backup. Option D is wrong because Launch Wizard provides cost estimates but does not automatically optimize deployment for cost; cost optimization requires separate analysis.

Answer

It provides a fully automated migration from on-premises to AWS

Answer

It manages the backup and disaster recovery of the SAP system

Answer

It automatically optimizes the deployment for cost

Question 10

Which THREE factors are essential when planning the migration of an SAP system with near-zero downtime requirements? (Choose three.)

Accepted Answer

Network bandwidth between source and target. For near-zero downtime migration, network bandwidth (A) determines the speed of initial and delta data transfer, directly impacting the cutover window. Data volume and change rate (B) affect the feasibility of completing delta syncs within the allowed downtime. The ability to perform a final delta sync (D) is crucial to minimize the final cutover window by synchronizing only changes since the last sync. Performance testing strategy (C) can be done post-migration and does not directly affect downtime planning. Storage type choice (E) impacts performance but not the downtime itself, as long as sufficient throughput is available.

Answer

Performance testing strategy for the target system

Answer

Choice of storage type (EBS vs. EFS)

Question 11

A company is migrating SAP HANA to AWS and needs to ensure high availability. The database must be replicated synchronously across two Availability Zones with automatic failover. Which AWS service should be used?

Accepted Answer

SAP HANA System Replication (HSR) with Pacemaker. SAP HANA System Replication (HSR) with Pacemaker provides synchronous replication and automatic failover, making it the appropriate solution for high availability across Availability Zones. Amazon EBS Multi-Attach is incorrect because it is limited to a single AZ and not designed for SAP HANA replication. AWS DMS is for database migration, not ongoing HA. Amazon RDS Multi-AZ is for RDS databases and does not support SAP HANA.

Answer

Amazon EBS Multi-Attach volumes

Answer

AWS Database Migration Service (DMS)

Answer

Amazon RDS Multi-AZ deployment

Question 12

An organization is migrating a critical SAP workload to AWS. They need to ensure compliance with SAP's 'Bring Your Own License' (BYOL) model. Which THREE steps should they take?

Accepted Answer

Verify that the SAP licenses are eligible for migration to AWS. The correct answers are C, D, and E. Option C is correct because you must verify that your SAP licenses are eligible for migration to AWS under the BYOL model. Option D is correct because using Dedicated Hosts or Dedicated Instances is required to meet SAP licensing requirements for BYOL. Option E is correct because SAP software must be deployed on instances that support 'software license mobility' to comply with the BYOL model. Option A is incorrect because SAP BYOL does not allow unrestricted migration of licenses; you must adhere to specific licensing terms. Option B is incorrect because AWS License Manager is an optional tool for license tracking, not a mandatory step for BYOL compliance.

Answer

Migrate existing SAP licenses to AWS without any restrictions

Answer

Use AWS License Manager to track and manage licenses

Question 13

A company is migrating their SAP S/4HANA system to AWS. They plan to use SAP HANA Cockpit for migration. During the pre-migration assessment, they find that the on-premises HANA system uses a mix of row and column store tables. The target AWS HANA instance is provisioned on a memory-optimized instance. They want to ensure optimal performance post-migration. Which additional step should they take?

Accepted Answer

Convert row store tables to column store tables where possible. Converting row store tables to column store improves performance for analytical workloads, which is typical for S/4HANA. Option A is wrong because reducing memory allocation could degrade performance. Option B is wrong because disabling compression would increase storage and memory usage. Option D is wrong because increasing parallelism may not help if the storage layout is suboptimal.

Answer

Reduce the memory allocation of the HANA instance

Answer

Disable data compression on the target HANA instance

Answer

Increase the number of HANA index servers

Question 14

Which TWO methods can be used to migrate an SAP system from on-premises to AWS while minimizing the need for re-architecture? (Choose two.)

Accepted Answer

Rehost by manually copying servers to Amazon EC2. Lift-and-shift (rehost) using AWS Application Migration Service and the 7-Migration Strategies (7Rs) rehost approach minimize re-architecture. Option A is wrong because replatforming involves some changes. Option D is wrong because refactoring involves significant re-architecture. Option E is wrong because AWS DMS is for databases, not full systems.

Answer

Replatform by moving to Amazon RDS for SAP

Answer

Refactor the application to use microservices

Answer

Use AWS Database Migration Service to move the database to Amazon Aurora

Question 15

An SAP system on AWS uses a Multi-AZ RDS for SQL Server as the database. During a failover test, the application experienced a 2-minute outage. The application team wants to reduce this downtime. What should the operations team recommend?

Accepted Answer

Enable automatic failover handling in the application's JDBC connection string.. Enabling Multi-AZ with automatic failover in the JDBC connection string allows the application to automatically reconnect to the new primary without manual intervention. Option A is wrong because increasing instance size does not affect failover time. Option B is wrong because a different Multi-AZ configuration does not reduce failover time. Option D is wrong because RDS Proxy is not supported for SQL Server.

Answer

Increase the DB instance size to improve failover performance.

Answer

Configure Multi-AZ with SQL Server Mirroring instead of Always On Availability Groups.

Answer

Use Amazon RDS Proxy to manage connections.
