PAS-C01 Practice Test 47 — 15 Questions

Question 1

A company wants to migrate its SAP ERP system from on-premises to AWS using the SAP Application Performance Standard (SAPS) sizing approach. The current on-premises system has a SAPS rating of 15,000. The company needs to select an EC2 instance type that can provide sufficient compute capacity. Which EC2 instance family is most suitable for SAP HANA workloads?

Accepted Answer

x1e. Option A is correct because SAP HANA is memory-intensive and x1e instances are certified for HANA. Option B is wrong because c5 is compute-optimized, not memory-optimized. Option C is wrong because m5 is general purpose. Option D is wrong because p3 is GPU-optimized.

Answer

c5

Answer

p3

Answer

m5

Question 2

An SAP system running on AWS is configured with a Multi-AZ RDS for SAP HANA database. The primary database fails, but the automatic failover does not occur. What is the most likely reason?

Accepted Answer

Multi-AZ is not supported for RDS for SAP HANA. Option B is correct because Multi-AZ for RDS for SAP HANA is not supported; RDS for SAP HANA does not have Multi-AZ capability. Option A is incorrect because RDS does not use Elastic IPs. Option C is incorrect because Multi-AZ is not a paid option; it incurs costs but is not disabled by billing. Option D is incorrect because RDS for HANA does not use EBS snapshots for replication.

Answer

The Multi-AZ configuration was not paid for

Answer

The standby instance was not configured with EBS snapshots

Answer

The primary instance does not have an Elastic IP attached

Question 3

A company is running SAP HANA on an EC2 instance. The storage is configured with multiple EBS volumes striped using LVM. The SAP administrator notices that disk I/O latency spikes during peak hours. Which change would MOST effectively reduce latency without incurring additional cost?

Accepted Answer

Use an EBS-optimized EC2 instance type. Option B is correct because EBS-optimized instances provide dedicated network bandwidth for EBS I/O, reducing contention. Option A is incorrect because increasing volume size does not directly reduce latency. Option C is incorrect because RAID 0 increases throughput but not lower latency. Option D is incorrect because provisioning IOPS increases cost.

Answer

Increase the size of the EBS volumes

Answer

Provision additional IOPS on the EBS volumes

Answer

Switch from LVM to RAID 0 striping

Question 4

An SAP system is deployed on EC2 instances in a VPC. The security team requires that all traffic between the SAP application and database tiers must be encrypted in transit. Which TWO actions should be taken to meet this requirement? (Choose two.)

Accepted Answer

Configure SSL/TLS certificates on the database and application servers. Options A and D are correct: an SSL/TLS certificate enables encryption, and security group rules should restrict traffic to only necessary ports. Option B is incorrect because NACLs are stateless and do not encrypt traffic. Option C is incorrect because VPC Peering does not encrypt traffic by itself. Option E is incorrect because Internet Gateway is for internet traffic.

Answer

Attach an Internet Gateway to the VPC

Answer

Create a VPC Peering connection between the subnets

Answer

Use network ACLs to allow only database traffic

Question 5

An SAP system uses an NFS share from an EFS file system for transport files. Recently, the transport directory performance has degraded. Which change would most likely improve performance?

Accepted Answer

Enable Provisioned Throughput on the EFS file system.. Option B is correct because using Provisioned Throughput on EFS ensures consistent performance regardless of file system size. Option A is wrong because increasing burst credits only helps temporarily. Option C is wrong because FSx for Lustre is for high-performance computing, not general purpose NFS. Option D is wrong because moving to S3 would require application changes.

Answer

Increase the burst credit balance by creating more files.

Answer

Migrate the transport directory to Amazon FSx for Lustre.

Answer

Use Amazon S3 with an NFS mount via AWS Storage Gateway.

Question 6

An SAP system running on AWS is experiencing performance degradation. The system uses a shared file system for /sapmnt and /usr/sap/trans. The file system is hosted on an Amazon EFS file system. Which configuration change is most likely to improve throughput for these file systems?

Accepted Answer

Change the EFS performance mode to Max I/O to support higher levels of aggregate throughput and operations per second.. Option D is correct because EFS performance mode 'Max I/O' is designed for high throughput and parallel operations, typical for SAP shared mounts. Option A is wrong because General Purpose (Burstable) mode is for lower throughput workloads. Option B is wrong because Provisioned Throughput is for consistent throughput but not specifically for parallel access. Option C is wrong because increasing burst credit balance is not a configuration option; burst credits are earned automatically.

Answer

Increase the Provisioned Throughput of the EFS file system.

Answer

Switch the EFS file system to General Purpose (Burstable) performance mode.

Answer

Enable burst credits on the EFS file system to handle peak loads.

Question 7

Refer to the exhibit. An SAP HANA administrator runs the command to check the attached volume. The volume is attached to an instance but the database is reporting low IOPS. What should the administrator check next?

Accepted Answer

Check if the EC2 instance is EBS-optimized and has sufficient network bandwidth.. Option D is correct because the volume is io1 with 10,000 IOPS, but the instance may not have EBS-optimized enabled, limiting throughput. Option A is wrong because the volume type is io1, not gp2. Option B is wrong because the volume size (500 GB) does not directly affect IOPS. Option C is wrong because NVMe driver is for instance store volumes, not EBS.

Answer

Check if the volume size is sufficient; increase to 1 TB.

Answer

Check if the volume type should be changed to gp2 for better burst performance.

Answer

Check if the instance is using the NVMe driver for the EBS volume.

Question 8

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 9

An SAP system administrator is setting up monitoring for SAP NetWeaver on AWS. They want to send custom SAP application metrics to CloudWatch for alerting. What is the most efficient way to achieve this?

Accepted Answer

Install the Amazon CloudWatch Agent on the EC2 instance and configure it to collect SAP metrics. The CloudWatch Agent can collect custom metrics from the OS and applications, including SAP, and publish them to CloudWatch. AWS Lambda can be used but requires custom code and more overhead. SAP Solution Manager does not natively integrate with CloudWatch. AWS Systems Manager is for management, not custom metric publishing.

Answer

Use SAP Solution Manager to export metrics to CloudWatch via API

Answer

Use AWS Lambda to periodically query SAP and push metrics to CloudWatch

Answer

Configure AWS Systems Manager to collect SAP metrics

Question 10

An SAP system administrator is configuring an SAP HANA database on an EC2 instance with multiple EBS volumes. The administrator wants to ensure that the data volumes are mirrored to protect against volume failure. Which RAID configuration should the administrator use for the HANA data volumes?

Accepted Answer

RAID 10. Option A is correct because RAID 10 (striping + mirroring) provides both performance and redundancy, recommended for HANA data. Option B is wrong because RAID 0 provides no redundancy. Option C is wrong because RAID 5 has write penalty. Option D is wrong because RAID 6 has higher write penalty.

Answer

RAID 5

Answer

RAID 0

Answer

RAID 6

Question 11

An SAP administrator needs to back up SAP HANA database to Amazon S3. Which AWS service or feature should be used to automate this backup?

Accepted Answer

SAP HANA Backup and Recovery with Backint. Option B is correct because the SAP HANA Backup and Recovery feature can back up directly to S3 via the Backint agent. Option A is incorrect because S3 Lifecycle policies manage object retention, not backup initiation. Option C is incorrect because AWS Backup supports some databases but not SAP HANA directly. Option D is incorrect because EBS snapshots capture the entire volume, not just the HANA database, and are not SAP HANA-aware.

Answer

Amazon EBS snapshots

Answer

AWS Backup

Answer

S3 Lifecycle policies

Question 12

An SAP system running on AWS experienced a database failure. The recovery plan uses cross-Region Amazon RDS snapshots. The RPO is 15 minutes and the RTO is 2 hours. Which AWS service should be used to automate snapshot replication across Regions?

Accepted Answer

AWS Backup. Option C is correct because AWS Backup can automate cross-Region snapshot copying with scheduling. Option A is incorrect because RDS automated backups are region-specific and cannot be cross-Region. Option B is incorrect because S3 Cross-Region Replication is for objects, not RDS snapshots. Option D is incorrect because CloudFormation does not automate snapshot replication.

Answer

AWS CloudFormation

Answer

Amazon RDS automated backups

Answer

Amazon S3 Cross-Region Replication

Question 13

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 14

A company is running SAP on AWS and wants to automate the installation of SAP applications using infrastructure as code. Which AWS service should be used to define the infrastructure?

Accepted Answer

AWS CloudFormation. Option D is correct because AWS CloudFormation allows defining infrastructure as code. Option A is wrong because OpsWorks is for Chef/Puppet. Option B is wrong because Elastic Beanstalk is for web applications. Option C is wrong because CodeDeploy is for application deployment, not infrastructure.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Elastic Beanstalk

Question 15

A company is troubleshooting an issue where SAP users cannot log in to the SAP GUI. The SAP application server is running on an EC2 instance behind an Application Load Balancer (ALB). The ALB is configured to use the HTTPS listener on port 443. Which configuration is most likely causing the issue?

Accepted Answer

The ALB is terminating HTTPS connections, but the SAP application server expects unencrypted DIAG protocol.. Option B is correct because SAP GUI typically uses DIAG protocol over TCP 3200, not HTTPS. The ALB should have a Network Load Balancer for TCP traffic. Option A is wrong because listener on 443 is fine for HTTPS but not for SAP GUI traffic. Option C is wrong because security group rules are not the primary issue. Option D is wrong because health checks are not directly related to user login.

Answer

The ALB's target group is not configured with health checks.

Answer

The security group for the ALB does not allow inbound traffic on port 3300.

Answer

The ALB's stickiness settings are misconfigured, causing session persistence issues.
