PAS-C01 Practice Test 37 — 15 Questions

Question 1

An SAP system on AWS sends large amounts of batch data via RFC calls between two EC2 instances in the same VPC. The application team reports high network latency. Which configuration change would most effectively reduce latency?

Accepted Answer

Place both EC2 instances in the same cluster placement group.. Option A is correct because placement groups provide low latency, high throughput networking. Option B is wrong because ENA is already recommended for enhanced networking. Option C is wrong because Elastic Fabric Adapter is for HPC, not general SAP. Option D is wrong because public IPs do not reduce latency within VPC.

Answer

Assign Elastic IP addresses to both instances.

Answer

Enable Elastic Network Adapter (ENA) on both instances.

Answer

Use Elastic Fabric Adapter (EFA) for network communication.

Question 2

A company is running an SAP HANA database on an EC2 instance with EBS volumes. The database experiences high write latency during peak hours. Which configuration change would most effectively reduce latency?

Accepted Answer

Use EBS io2 Block Express volumes with multi-attach enabled.. Option B is correct because using EBS io2 Block Express volumes provides consistent low latency and high IOPS for demanding workloads like SAP HANA. Option A is wrong because gp3 volumes have lower performance compared to io2 Block Express. Option C is wrong because increasing instance size may not directly address storage latency. Option D is wrong because instance store volumes are ephemeral and not suitable for persistent database storage.

Answer

Switch to gp3 EBS volumes with maximum throughput.

Answer

Increase the EC2 instance size to a compute-optimized type.

Answer

Migrate the data to instance store volumes.

Question 3

An SAP administrator runs the above CLI command and sees the output. The EC2 instance i-0a1b2c3d4e5f6g7h8 is stopped. What will happen if the administrator attempts to start the instance?

Accepted Answer

The instance will start successfully and the volume will be attached.. Option A is correct. The volume is of type io2 with 10,000 IOPS, which is supported. The instance start will attach the volume and boot normally. Option B is wrong because volume type is supported. Option C is wrong because multi-attach is disabled but not required. Option D is wrong because size is acceptable.

Answer

The instance will fail to start because the volume type is not supported.

Answer

The instance will start but the volume will not attach because multi-attach is disabled.

Answer

The instance will start but the volume will be read-only.

Question 4

An SAP administrator notices that the SAP HANA database performance has degraded significantly during peak hours. The HANA instance is running on an r5.8xlarge EC2 instance with EBS gp2 volumes. Monitoring shows high I/O wait times on the data volume. Which change is MOST likely to improve performance?

Accepted Answer

Use Amazon EBS io2 Block Express volumes with high IOPS.. Option D is correct because switching to io2 volumes with provisioned IOPS provides consistent low-latency I/O, solving high I/O wait. Option A (increasing instance size) may not address I/O bottleneck. Option B (gp3) is better than gp2 but still burstable. Option C (enable Multi-AZ) does not improve I/O performance.

Answer

Enable Multi-AZ deployment for SAP HANA.

Answer

Upgrade the EC2 instance to a larger size like r5.16xlarge.

Answer

Change the EBS volume type from gp2 to gp3 with 3000 IOPS.

Question 5

A company is running an SAP HANA database on an Amazon EC2 instance. The storage is configured with multiple EBS volumes striped using LVM. The company wants to ensure the database performance is consistent and can detect potential bottlenecks. Which AWS service should be used to monitor the EBS volume metrics such as Average Queue Length and Throughput?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch provides metrics for EBS volumes including Average Queue Length (VolumeQueueLength) and Throughput (VolumeReadBytes/VolumeWriteBytes). Option A is correct. AWS CloudTrail records API calls, not performance metrics. AWS Trusted Advisor provides best-practice checks but not detailed EBS metrics. Amazon Inspector is for security assessments.

Answer

AWS Trusted Advisor

Answer

Amazon Inspector

Answer

AWS CloudTrail

Question 6

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 offers several automation tools: CloudFormation with a custom template (A), AWS Launch Wizard for SAP (B), and SAP Cloud Appliance Library (C) all can automate HANA installation. AWS Systems Manager (D) can run scripts but not a full HANA installation out-of-the-box. OpsWorks (E) is for Chef/Puppet, not directly for HANA.

Answer

AWS Systems Manager Automation

Answer

AWS OpsWorks

Question 7

An SAP administrator needs to ensure that all API calls made to AWS services by the SAP system are logged for auditing purposes. Which AWS service should be enabled?

Accepted Answer

AWS CloudTrail. Option B is correct because AWS CloudTrail logs all API calls to AWS services. Option A is wrong because Amazon CloudWatch is for metrics and logs. Option C is wrong because AWS Config records resource configurations. Option D is wrong because VPC Flow Logs capture IP traffic information.

Answer

AWS Config

Answer

Amazon CloudWatch

Answer

VPC Flow Logs

Question 8

A company is running SAP HANA on a bare metal EC2 instance. The system experiences a hardware failure that causes an instance stop. The company needs to recover the instance quickly. What should the company do to minimize recovery time?

Accepted Answer

Configure an Amazon CloudWatch alarm to automatically recover the instance. For bare metal instances, automatic recovery via CloudWatch alarm can restart the instance on healthy hardware if the instance is configured with an Elastic IP or is part of an ASG. Option B is correct. Manual restart (A) is slower. EBS snapshots (C) require restore time. Changing to a virtualized instance (D) may not be immediate.

Answer

Use AWS CloudFormation to recreate the instance

Answer

Manually start the instance from the EC2 console

Answer

Restore the instance from the latest EBS snapshot

Question 9

A company is migrating its SAP landscape to AWS. The SAP systems consist of multiple instances (development, quality, production) running on different EC2 instances. The company wants to automate the provisioning of these instances using infrastructure as code. Which AWS service should be used to define and provision the SAP infrastructure in a repeatable manner?

Accepted Answer

AWS CloudFormation. Option B is correct because AWS CloudFormation allows you to define infrastructure as code in templates and provision resources in a repeatable manner. Option A is wrong because AWS Elastic Beanstalk is for deploying applications, not for defining infrastructure. Option C is wrong because OpsWorks is for configuration management, not infrastructure provisioning. Option D is wrong because AWS Service Catalog is for creating and managing a catalog of approved IT services.

Answer

AWS Elastic Beanstalk

Answer

AWS Service Catalog

Answer

AWS OpsWorks

Question 10

Refer to the exhibit. An IAM policy is attached to an IAM role used by an SAP automation script. The script is failing to start an EC2 instance. What is the most likely cause?

Accepted Answer

The script is not using HTTPS, so the Deny statement blocks all actions.. Option A is correct because the policy has an explicit Deny effect when aws:SecureTransport is false, meaning the script must use HTTPS. If the script uses HTTP (non-secure transport), the Deny statement blocks all actions including StartInstances. Option B is wrong because the policy allows ec2:StartInstances on all resources. Option C is wrong because the policy allows ec2:DescribeInstances and StartInstances. Option D is wrong because the policy allows s3:GetObject and s3:PutObject on the specific bucket.

Answer

The policy does not grant permission to start instances.

Answer

The policy does not allow ec2:DescribeInstances.

Answer

The script does not have access to the S3 bucket.

Question 11

A company has a mission-critical SAP S/4HANA system running on AWS with a multi-node HANA database. The system must be highly available with an RPO of 0 and an RTO of less than 30 minutes. The database uses SAP HANA System Replication (HSR) with synchronous replication. Which THREE components are essential for this high-availability architecture?

Accepted Answer

An ENSA2 (Enqueue Replication 2) enqueue server.. Options A, C, and D are correct: A secondary HANA instance in a different AZ provides failover; a cluster manager (e.g., Pacemaker) manages failover; an ENSA2 enqueue server ensures data consistency. Option B is wrong: An Application Load Balancer is for HTTP traffic, not HANA. Option E is wrong: A VPN connection is not required for AWS internal traffic.

Answer

An Application Load Balancer to distribute traffic between HANA nodes.

Answer

A VPN connection between the two Availability Zones.

Question 12

A company is migrating an SAP ERP system to AWS. The system requires low-latency access to a shared file system for SAP transport directories. The file system must be accessible from multiple EC2 instances in different Availability Zones. Which storage solution meets these requirements?

Accepted Answer

Amazon EFS file system.. Option C is correct because Amazon EFS provides a shared file system accessible from multiple AZs with low latency. Option A is wrong because instance store is ephemeral and not shared. Option B is wrong because EBS volumes can only be attached to one instance at a time. Option D is wrong because S3 is object storage, not a file system.

Answer

Amazon EBS volumes snapshotted and shared across instances.

Answer

Instance store volumes on each EC2 instance.

Answer

Amazon S3 with Transfer Acceleration.

Question 13

A company is running an SAP HANA database on an EC2 instance with a large amount of memory. The system is experiencing performance issues during peak loads. Which AWS service should be used to capture detailed performance metrics for analysis?

Accepted Answer

Amazon CloudWatch. Option D is correct because Amazon CloudWatch can collect detailed performance metrics from EC2 instances, including memory utilization, if the CloudWatch agent is installed. Option A is wrong because AWS CloudTrail records API activity, not performance metrics. Option B is wrong because AWS Config tracks resource configuration changes. Option C is wrong because AWS X-Ray traces application requests, not system-level performance.

Answer

AWS Config

Answer

AWS CloudTrail

Answer

AWS X-Ray

Question 14

Which THREE considerations are important when designing an SAP HANA multi-node (scale-out) deployment on AWS? (Choose three.)

Accepted Answer

Use a cluster placement group for low-latency network.. Options A, C, and D are correct. SAP HANA multi-node requires low latency between nodes, so placement groups are recommended (A). Each node needs its own EBS volume for data and log (C). The number of nodes is limited by the instance type's networking and EBS bandwidth (D). Option B is wrong because multi-node uses multiple instances, not a single large instance. Option E is wrong because EBS Multi-Attach is not supported for HANA; each node needs its own volume.

Answer

Use EBS Multi-Attach to share volumes between nodes.

Answer

Use a single large EC2 instance with many vCPUs.

Question 15

A company is running SAP NetWeaver on AWS and wants to implement high availability for the ASCS instance. Which AWS service can be used to monitor and automatically restart the ASCS instance if it fails?

Accepted Answer

Amazon CloudWatch with EC2 Auto Recovery. Option B is correct because Amazon CloudWatch can monitor instance status and trigger an Auto Recovery action to restart the instance in the same Availability Zone. Option A is wrong because ELB is for traffic distribution, not instance recovery. Option C is wrong because Lambda can perform actions but not directly restart instances without additional setup; CloudWatch Auto Recovery is simpler. Option D is wrong because EC2 Auto Scaling is for scaling groups, not single instance recovery.

Answer

EC2 Auto Scaling group

Answer

AWS Lambda with a scheduled function

Answer

Elastic Load Balancing (ELB)
