PAS-C01 Practice Exam 57 — 20 Questions

Question 1

A company is migrating an SAP system to AWS and needs to ensure that the SAP application can communicate with the database over a low-latency, high-bandwidth connection. What is the best practice for network architecture?

Accepted Answer

Place the SAP application and database in the same VPC and same Availability Zone.. Placing the SAP application and database in the same VPC and Availability Zone minimizes latency. Separate AZs increase latency. Different regions introduce significant latency. On-premises connection defeats purpose of migration.

Answer

Place the SAP application on-premises and the database on AWS.

Answer

Place the SAP application and database in separate Availability Zones within the same region.

Answer

Place the SAP application in a different AWS Region than the database.

Question 2

An SAP administrator runs the AWS CLI command shown in the exhibit. The SAP application is experiencing performance issues. The administrator notices that one instance is stopped. What is the most likely impact of this on the SAP landscape?

Accepted Answer

The SAP application will be unavailable or have reduced capacity.. If the SAP application server is stopped, the application will be unavailable or degraded. The database is not shown. Stopped instances do not incur compute charges. Instance type mismatch is not the issue; the running instance is larger.

Answer

The SAP system will be fully functional as long as the database is running.

Answer

The running instance will automatically take over the workload.

Answer

The stopped instance will continue to incur charges.

Question 3

A company is migrating its SAP ERP system to AWS and needs to ensure that the SAP license is compliant. The company has a production license for SAP ERP. What should the company do for licensing on AWS?

Accepted Answer

Use the existing SAP license under the Bring Your Own License (BYOL) model.. Option B is correct because AWS allows bring-your-own-license (BYOL) for SAP, and the company can reuse its existing license. Option A is wrong because SAP does not provide a free license for AWS. Option C is wrong because purchasing a new license is unnecessary. Option D is wrong because subscription is an option but not required.

Answer

Request a free SAP license for AWS from SAP.

Answer

Use a subscription-based SAP license from the AWS Marketplace.

Answer

Purchase a new SAP license for AWS.

Question 4

A company is migrating an SAP NetWeaver system from on-premises to AWS. They plan to use the same SAP SID and keep the same hostname. The migration will be performed using SAP Software Provisioning Manager (SWPM) with the option 'System Rename' set to 'No'. What must be configured in the AWS environment to ensure the system functions correctly?

Accepted Answer

Ensure the same private IP address is assigned to the Amazon EC2 instance. Option A is incorrect because the system uses the same hostname, so DNS updates are not needed. Option B is incorrect because AWS does not enforce different private IPs; the old IP can be reused. Option C is incorrect because the same SAP SID is allowed; no change required. Option D is correct because the Amazon EC2 instance must have the same private IP as the on-premises hostname resolves to, or the hostname must be resolvable via DNS or /etc/hosts.

Answer

Update the DNS records to point to the new public IP

Answer

Change the SAP SID to a new value

Answer

Assign a different private IP address to avoid conflicts

Question 5

Which THREE actions should be taken to ensure minimal downtime during an SAP system migration to AWS using SAP HSR (HANA System Replication)?

Accepted Answer

Perform a takeover to the target system to finalize migration.. To minimize downtime, you need to replicate data in advance, configure a takeover, and pre-create resources. Option A ensures the target is ready. Option B is the core replication mechanism. Option C allows quick cutover. Option D is wrong because disabling backup does not reduce downtime and risks data loss. Option E is wrong because manual sync is not needed with HSR.

Answer

Disable backups on the source system to reduce load.

Answer

Manually copy data files to AWS before starting replication.

Question 6

A company is migrating a critical Oracle database to Amazon RDS for Oracle. The database is 2 TB in size and has a high transaction rate. The migration must have minimal downtime. Which TWO AWS services or features should be used to achieve this? (Choose two.)

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication. AWS DMS with ongoing replication (change data capture) is the correct approach for minimal downtime migration. AWS Schema Conversion Tool (SCT) is used for schema conversion, which is necessary when moving to RDS Oracle. Option B (AWS Server Migration Service) is for server migration, not databases. Option C (AWS DataSync) is for file/object transfers. Option D (AWS Snowball) is for large offline data transfer, not suitable for minimal downtime.

Answer

AWS DataSync

Answer

AWS Snowball

Answer

AWS Server Migration Service (SMS)

Question 7

A company is migrating a .NET application running on Windows Server to AWS. They plan to use Amazon EC2 with a Windows license included. The current application uses SQL Server Standard edition. Which migration strategy minimizes licensing costs?

Accepted Answer

Use Amazon RDS for SQL Server with License Included pricing.. Option C is correct because using RDS SQL Server with License Included eliminates the need for SQL Server licenses. Options A, B, and D are incorrect: BYOL requires existing licenses; Dedicated Hosts and Dedicated Instances are more expensive and unnecessary.

Answer

Lift and shift to EC2 with SQL Server BYOL on Dedicated Hosts.

Answer

Use EC2 with SQL Server Standard on Dedicated Instances to ensure isolation.

Answer

Use EC2 with SQL Server Web edition, which is cheaper but may not support all features.

Question 8

A company is migrating a large SAP ERP system to AWS. Which TWO AWS services are essential for high availability and disaster recovery? (Choose two.)

Accepted Answer

AWS Elastic Disaster Recovery (DRS). Correct options: B and D. Route 53 provides DNS failover; AWS Elastic Disaster Recovery enables replication and recovery. Options A, C, and E are incorrect: S3 is storage; CloudWatch is monitoring; DMS is for databases, not full system recovery.

Answer

Amazon CloudWatch

Answer

AWS Database Migration Service

Answer

Amazon S3

Question 9

A company is migrating its SAP ERP system to AWS. The system uses an SAP HANA database and runs on SUSE Linux Enterprise Server (SLES). The company wants to use the same SLES version on AWS and needs to ensure that the instance type supports the required SAP HANA workload. Which AWS resource should the administrator use to find the appropriate instance types?

Accepted Answer

The SAP Certified and Supported SAP HANA Hardware Directory on the SAP website.. Option A is correct because the SAP Certified and Supported SAP HANA Hardware Directory lists all AWS instance types certified for SAP HANA. The administrator can filter by provider, OS, and instance type. Options B, C, D are incorrect because they do not provide the certified hardware list.

Answer

The AWS Well-Architected Framework documentation.

Answer

The SAP on AWS Implementation Guide.

Answer

The AWS Trusted Advisor console.

Question 10

A company is planning to migrate an SAP BusinessObjects environment to AWS. They need to ensure high availability for the Web Application Server tier. Which AWS service should they use to distribute traffic across multiple instances?

Accepted Answer

Application Load Balancer (ALB). An Application Load Balancer (ALB) distributes HTTP/HTTPS traffic across targets. NLB is for TCP/UDP. Global Accelerator improves performance but not primarily for load balancing. Route 53 is DNS.

Answer

AWS Global Accelerator

Answer

Network Load Balancer (NLB)

Answer

Amazon Route 53

Question 11

An administrator uses AWS Launch Wizard to deploy an SAP S/4HANA system with high availability. After deployment, they notice that only one database instance is created. What is the most likely reason?

Accepted Answer

The deployment encountered an error and only created one instance.. High availability for SAP HANA typically requires at least two nodes (primary and secondary). If only one is created, the HA configuration may have failed or the parameter was ignored. The backup retention and instance classes are correct.

Answer

The instance class r5.8xlarge is not certified for HANA.

Answer

The HighAvailability parameter was set to false.

Answer

The Launch Wizard does not support HA for HANA.

Question 12

A company is migrating its SAP system to AWS. The system uses a custom ABAP program that writes to a local file system. Which TWO AWS services can the company use to provide a shared file system accessible to multiple EC2 instances?

Accepted Answer

Amazon FSx for Lustre. Options A and C are correct. Amazon EFS provides a NFS file system that can be mounted on multiple Linux instances. Amazon FSx for Lustre is a high-performance file system for HPC workloads. Option B is wrong because Amazon S3 is object storage. Option D is wrong because Amazon EBS can only be attached to one instance. Option E is wrong because Amazon RDS is a database service.

Answer

Amazon RDS

Answer

Amazon S3

Answer

Amazon EBS

Question 13

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size. The migration window is limited to 3 days. Which AWS service should be used to perform the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is designed for large data transfers when network bandwidth is limited. The 2 TB database can be physically shipped and loaded onto AWS. AWS Direct Connect is for ongoing connectivity, not bulk transfer. AWS DataSync is for smaller datasets over the network. AWS DMS is for ongoing replication and requires network bandwidth.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Direct Connect

Question 14

Which THREE considerations are important when planning the migration of an SAP HANA database to AWS using HANA System Replication (HSR)?

Accepted Answer

The target EC2 instance must have at least the same amount of RAM as the source.. HSR requires network latency below 10 ms for synchronous replication, and the target instance must have sufficient memory and storage. Network bandwidth is important but not the only factor. The source and target can be in different Regions, but latency must be acceptable. Encryption is not a prerequisite for HSR.

Answer

The source and target must be in the same AWS Region.

Answer

The source database must be encrypted before replication can start.

Question 15

Amazon S3 Transfer Acceleration

Question 18

Refer to the exhibit. An EC2 instance is running and has a public IP address. A security engineer needs to verify that the instance is not publicly accessible from the internet. Which additional step is required?

Accepted Answer

Check the security group inbound rules.. Option C is correct because the security group rules determine inbound access. Option A is incorrect because NACLs are not shown. Option B is incorrect because the instance has a public IP. Option D is incorrect because subnet routing does not affect inbound security.

Answer

Check if the instance has a public IP.

Answer

Check the route table for an internet gateway.

Answer

Check the network ACL of the subnet.

Question 19

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as its database. The company has a complex networking setup with multiple VPCs and on-premises connectivity via AWS Direct Connect. The SAP HANA system replication will be used for high availability across two Availability Zones. What is the minimum number of Elastic Network Interfaces (ENIs) required per HANA instance to support the recommended network architecture?

Accepted Answer

2. Option B is correct because the recommended architecture for SAP HANA on AWS with system replication uses three ENIs per HANA instance: one for management/backup, one for client-facing traffic, and one for replication. Option A is too few, Options C and D are not standard.

Answer

1
