PAS-C01 Mock Exam 82 — 25 Questions

Question 1

A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for the migration. The on-premises network team reports that the Direct Connect link is consistently at 80% utilization during business hours. What should the company do to ensure a successful migration without impacting production traffic?

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

Accepted Answer

Schedule the migration during off-peak hours to avoid high utilization.. The correct approach is to schedule the migration during off-peak hours when the link utilization is lower to avoid congestion. Increasing bandwidth may not be feasible immediately. Using VPN over the internet may add latency and security concerns. Snowball is for large data volumes, but if the data volume is manageable, off-peak migration is simpler.

Answer

Increase the bandwidth of the Direct Connect link.

Answer

Use AWS Site-to-Site VPN over the internet as an alternative.

Answer

Use AWS Snowball Edge to transfer the data physically.

Question 2

A company is migrating an SAP HANA database to AWS. They have set up HANA System Replication (HSR) between the on-premises primary and an AWS secondary. The initial data synchronization is complete, but during the final cutover, the replication breaks due to network latency. What should the company do to complete the migration successfully?

Accepted Answer

Perform a manual takeover to promote the AWS secondary to primary.. The correct action is to perform a manual failover using HSR takeover, which will promote the AWS secondary to primary and allow the system to continue. Increasing timeout may not resolve underlying latency. Restarting replication will take time. Setting up a new replication is unnecessary.

Answer

Set up a new HSR connection with a different port.

Answer

Increase the HSR timeout settings on the primary.

Answer

Restart the initial synchronization from scratch.

Question 3

An SAP system on AWS is using a Multi-AZ deployment for high availability. The SAP Central Services (ASCS) and Enqueue Replication Server (ERS) are running on separate EC2 instances. During a failover test, the ASCS instance fails, but the ERS does not take over. What is the most likely cause?

Accepted Answer

The floating IP address is not configured to move to the ERS instance. SAP Enqueue Replication requires a floating IP address (using AWS Elastic IP or Route 53) that moves from ASCS to ERS during failover. If the floating IP is not properly configured, the ERS cannot take over. DNS resolution is not the primary method. Health checks are not the issue. Instance type is irrelevant.

Answer

The ERS instance does not have the required security group rules

Answer

The DNS TTL is set too high

Answer

The ERS instance is in a different subnet

Question 4

An SAP system administrator needs to ensure that an EC2 instance running SAP can access an S3 bucket containing installation media. The instance is in a private subnet without internet access. What is the recommended way to provide access to S3?

Accepted Answer

Create a VPC Gateway Endpoint for S3.. A VPC Gateway Endpoint for S3 allows instances in a private subnet to access S3 without internet access. NAT Gateway is for internet access, Direct Connect is for on-premises connectivity, and VPN is for site-to-site.

Answer

Set up a VPN connection to S3.

Answer

Set up a NAT Gateway in the public subnet.

Answer

Use AWS Direct Connect to connect to S3.

Question 5

A company is deploying SAP NetWeaver on AWS and needs to ensure high availability for the SAP Central Services (ASCS) instance. Which TWO AWS features should be used together to achieve this?

Accepted Answer

Network Load Balancer (NLB). Amazon EFS provides a shared filesystem for the ASCS cluster, and a Network Load Balancer (NLB) is used to distribute traffic to the active ASCS instance. S3 is not suitable for shared files, and Multi-AZ for RDS is for databases, not ASCS.

Answer

Amazon RDS Multi-AZ

Answer

Application Load Balancer (ALB)

Answer

Amazon S3

Question 6

Refer to the exhibit. An SAP administrator has the IAM policy shown. The administrator needs to attach an EBS volume to an EC2 instance that is tagged with SAPSystem=DEV. Will the administrator be able to perform the attach operation?

Accepted Answer

No, because the condition requires the tag SAPSystem=PRD. The policy allows AttachVolume and DetachVolume actions, but only when the volume or instance resource has the tag SAPSystem=PRD. Since the instance is tagged DEV, the condition is not met, and the operation will be denied.

Answer

No, because the policy does not allow attaching volumes

Answer

Yes, because the policy allows the actions

Answer

Yes, because the resource is not restricted

Question 7

An SAP system uses an Application Load Balancer (ALB) to distribute traffic to web servers. The ALB is configured with a health check that fails, causing the web servers to be marked as unhealthy. What is a possible reason for the health check failure?

Accepted Answer

The web server is not configured to respond to the health check path. A common health check failure is when the health check path (e.g., /health) returns a non-200 status code. The security group allowing traffic from the ALB is required. Instance type does not affect health check. The subnet is not a direct cause.

Answer

The instance is in a private subnet

Answer

The instance type is not supported by the ALB

Answer

The security group for the ALB does not allow outbound traffic

Question 8

Answer

AWS CloudEndure Migration

Question 9

A company is migrating its SAP system to AWS and wants to use AWS Backup to manage backups of SAP HANA databases running on EC2 instances. What is the prerequisite for this integration?

Accepted Answer

The HANA database must be registered as a resource in AWS Backup using the Backint agent.. AWS Backup supports HANA databases via the SAP HANA Backint integration. The HANA database must be registered as a resource in AWS Backup, which requires the Backint agent. Options A (SAP HANA in-memory backup) is not a thing. Option B (Dedicated Host) is not required. Option C (not using EBS snapshots) is unnecessary.

Answer

The HANA database must be configured to use in-memory backups.

Answer

The HANA database must not use EBS snapshots for backup.

Answer

The EC2 instance must be running on a Dedicated Host.

Question 10

An organization is migrating a large SAP HANA workload to AWS. The current on-premises environment uses IBM Spectrum Scale (GPFS) for shared storage. Which AWS storage solution should they use to provide a similar shared file system for SAP HANA?

Accepted Answer

Amazon FSx for NetApp ONTAP. Amazon FSx for NetApp ONTAP provides a fully managed shared file system that supports NFS, SMB, and iSCSI protocols, and can replace GPFS for SAP HANA. EBS is block storage not shared. S3 is object storage. EFS is NFS but lacks some enterprise features needed for HANA.

Answer

Amazon S3

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Elastic File System (EFS)

Question 11

A company is running SAP ERP on AWS and using a shared file system for the SAP transport directory. The file system must be accessible from multiple EC2 instances in different Availability Zones. Which AWS storage solution should be used?

Accepted Answer

Amazon EFS. Amazon EFS provides a scalable, shared file system that can be mounted from multiple EC2 instances across Availability Zones. Amazon S3 is object storage, not a file system. Amazon FSx for Windows File Server is for Windows-based environments. Amazon EBS cannot be shared across instances.

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Answer

Amazon EBS

Question 12

A company is designing an SAP HANA disaster recovery solution using SAP HANA System Replication. Which TWO AWS services are required to enable automatic failover across AWS Regions?

Accepted Answer

AWS Elastic Load Balancing (NLB). AWS Route 53 provides DNS-based failover routing to redirect traffic to the DR region. AWS Elastic Load Balancing (NLB) is used to distribute traffic to the HANA instances and can be used with a floating IP. AWS Direct Connect is not required. AWS CloudFormation is not needed for automatic failover. AWS Shield is for DDoS protection.

Answer

AWS Direct Connect

Answer

AWS CloudFormation

Answer

AWS Shield

Question 13

A company wants to migrate its SAP HANA database to AWS and needs to minimize downtime. Which AWS service should be used for a near-zero downtime migration?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication and can migrate SAP HANA to AWS with minimal downtime. Server Migration Service (SMS) is for server migrations, Snowball is for large data transfers offline, and Direct Connect is for network connectivity.

Answer

AWS Direct Connect

Answer

AWS Snowball

Answer

AWS Server Migration Service (SMS)

Question 14

A company runs an SAP HANA database on an AWS EC2 instance. The database experiences high latency during peak hours. The operations team suspects network bottlenecks. Which AWS service should be used to analyze network traffic patterns and identify the source of latency?

Accepted Answer

VPC Flow Logs. VPC Flow Logs capture IP traffic information for network interfaces, enabling analysis of traffic patterns and bottlenecks. AWS CloudTrail logs API calls, not network traffic. AWS Trusted Advisor provides best-practice checks but not detailed network analysis. AWS X-Ray traces application requests, not network-level traffic.

Answer

AWS X-Ray

Answer

AWS Trusted Advisor

Answer

AWS CloudTrail

Question 15

Refer to the exhibit. An SAP administrator checks the configuration of an EBS volume. The volume is attached to an SAP HANA instance. What is the potential performance bottleneck?

Accepted Answer

The IOPS and throughput are too low for SAP HANA. The volume type is gp3 with 3000 IOPS and 125 MB/s throughput. SAP HANA requires high IOPS and throughput. With only 3000 IOPS and 125 MB/s, this volume may be a bottleneck for production HANA workloads. The DeleteOnTermination setting is not a performance issue. The size and snapshot are not immediate concerns.

Answer

The volume is attached to an instance in a different Availability Zone

Answer

The DeleteOnTermination flag is set to false

Answer

The volume is not encrypted

Question 16

A company is migrating an SAP ERP system to AWS. The migration must be completed within a limited time window. Which THREE services can be used to accelerate the migration? (Choose three.)

Accepted Answer

AWS CloudEndure Migration. Options A, B, and C are correct: AWS SMS (now MGN) can automate server replication, AWS DMS can migrate databases, and AWS CloudEndure (now part of MGN) can replicate servers. Option D is incorrect because Trusted Advisor is for optimization, not migration. Option E is incorrect because CloudFormation is for infrastructure provisioning, not data migration.

Answer

AWS Trusted Advisor

Answer

AWS CloudFormation

Question 17

An SAP system on AWS is experiencing high latency between the application server and the database server. Both are in the same VPC but different subnets. What is the most effective way to reduce latency?

Accepted Answer

Place both instances in a placement group in the same Availability Zone.. Placing both the SAP application server and database server in a placement group within the same Availability Zone ensures they are in close physical proximity, often on the same rack or within the same cluster. This minimizes network hops and reduces latency to single-digit microseconds, which is critical for SAP's high-throughput, low-latency communication between application and database layers.

Answer

Move the database to a different Availability Zone.

Answer

Use a VPN connection between subnets.

Answer

Increase the instance size of both servers.

Question 18

A company is migrating an on-premises SAP HANA database to AWS. The current HANA system uses 2 TB of storage and requires high IOPS. The company wants to use Amazon EBS for storage. Which EBS volume type is most suitable for the HANA data volume?

Accepted Answer

io2 Block Express. SAP HANA requires high IOPS and low latency, and io2 Block Express provides the highest performance for such requirements. Option A is wrong because sc1 is a cold HDD, which provides low IOPS and is not suitable for SAP HANA. Option B is wrong because st1 is throughput-optimized HDD, designed for large sequential workloads, not for high IOPS. Option C is wrong because gp3 is a general-purpose SSD; while it can provide up to 16,000 IOPS, io2 Block Express offers higher and more consistent IOPS and lower latency, making it the preferred choice for SAP HANA data volumes.

Answer

sc1

Answer

st1

Answer

gp3

Question 19

Accepted Answer

AWS Database Migration Service (AWS DMS) with a heterogeneous migration using the SAP HANA target endpoint. AWS DMS supports heterogeneous migrations, including from Oracle to SAP HANA, by using built-in conversion capabilities or integrating with AWS SCT for schema transformation. This allows continuous data replication with minimal downtime, as DMS can perform ongoing changes from the source during the migration window.

Answer

AWS Schema Conversion Tool (AWS SCT)

Answer

AWS Server Migration Service (SMS)

Answer

AWS Database Migration Service (AWS DMS) with a homogeneous migration

Question 20

An SAP administrator runs the df command on an SAP HANA server and sees the output above. The /hana/data filesystem is 96% full. Which action should be taken to prevent the database from running out of space?

Accepted Answer

Increase the size of the EBS volume and extend the filesystem. The correct action is to increase the size of the EBS volume and extend the filesystem because the /hana/data filesystem is 96% full, and SAP HANA requires sufficient free space for data growth and savepoint operations. Simply increasing the EBS volume size without extending the filesystem (e.g., using resize2fs or xfs_growfs) would not make the additional space available to the operating system. This approach directly addresses the capacity issue without unnecessary changes to performance or instance type.

Answer

Increase the IOPS of the EBS volume

Answer

Delete old database logs to free up space

Answer

Migrate the database to a larger instance type
