PAS-C01 Design of SAP Workloads on AWS Practice Test 24 — 15 Questions

Question 1

A company is deploying SAP S/4HANA on AWS. They need to choose the appropriate storage for the database volume to meet high IOPS and low latency requirements. Which AWS storage service should they use?

Accepted Answer

Amazon EBS io2 Block Express volumes. Amazon EBS io2 Block Express volumes provide high IOPS and low latency, suitable for SAP HANA database workloads. Option A is wrong because EBS gp3 is for general-purpose, not optimized for high IOPS. Option B is wrong because EFS is file storage, not block. Option D is wrong because S3 is object storage.

Answer

Amazon EFS

Answer

Amazon S3

Answer

Amazon EBS gp3 volumes

Question 2

An SAP administrator is designing a disaster recovery plan for SAP NetWeaver on AWS. They want to minimize RTO and RPO while keeping costs low. Which strategy should they use?

Accepted Answer

Use AWS Elastic Disaster Recovery (DRS) with SAP HANA system replication. Using AWS Elastic Disaster Recovery (DRS) with SAP HANA replication provides low RTO/RPO and cost-effective DR. Option A is wrong because EC2 Image Builder is for AMI creation, not DR. Option B is wrong because manual snapshots have higher RPO. Option D is wrong because S3 replication does not replicate running instances.

Answer

Use AWS EC2 Image Builder to create daily AMIs

Answer

Take manual EBS snapshots every 12 hours

Answer

Replicate SAP application data to an S3 bucket in another region

Question 3

A company runs SAP Business Suite on AWS with a large SAP HANA database. They observe high memory utilization and need to scale up. Which instance type should they choose to provide the highest memory capacity for SAP HANA?

Accepted Answer

u-12tb1.112xlarge. The u-12tb1.112xlarge instance provides 12 TB of memory, which is the highest among the options. Option A is wrong because the x1e.32xlarge has 3.9 TB. Option B is wrong because the r5.24xlarge has 768 GB. Option C is wrong because the m5.24xlarge has 384 GB.

Answer

r5.24xlarge

Answer

x1e.32xlarge

Answer

m5.24xlarge

Question 4

A company is migrating its SAP ERP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS architecture should they implement?

Accepted Answer

Configure a two-node cluster with a virtual IP (VIP) using AWS Route 53 health checks and failover. ASCS high availability requires a cluster with a virtual IP address managed by a load balancer or route table update. Option A is wrong because a single instance is not HA. Option B is wrong because Auto Scaling does not handle ASCS failover properly. Option D is wrong because Multi-AZ RDS is for databases, not ASCS.

Answer

Run ASCS on Amazon RDS for SAP with Multi-AZ

Answer

Deploy ASCS on a single large EC2 instance

Answer

Use an Auto Scaling group with a minimum of 2 instances

Question 5

An SAP administrator notices that the SAP HANA database backups to Amazon S3 are failing intermittently with timeout errors. The backup script uses the AWS CLI to copy files to an S3 bucket. What is the most likely cause and solution?

Accepted Answer

The backup files are large and the CLI command does not use multipart upload; use multipart upload and increase timeout values. Intermittent timeouts may be due to network connectivity issues or insufficient retries. Using multipart upload for large files and enabling retries can resolve this. Option A is wrong because S3 bucket policies do not cause timeouts. Option B is wrong because S3 Transfer Acceleration is for speed, not timeouts. Option D is wrong because S3 lifecycle policies do not affect uploads.

Answer

The S3 bucket policy is too restrictive, modify the policy

Answer

The S3 bucket has a lifecycle policy that deletes objects too quickly

Answer

S3 Transfer Acceleration is not enabled, enable it

Question 6

A company is planning to run SAP HANA on AWS. What is the recommended practice for sizing the EC2 instance for SAP HANA?

Accepted Answer

Select an instance type from the SAP HANA certified list on AWS. SAP HANA requires that the instance be certified for SAP HANA on AWS. Option A is wrong because memory is just one factor. Option B is wrong because vCPU count is not the primary criterion. Option D is wrong because network bandwidth is secondary.

Answer

Choose an instance with the highest network bandwidth

Answer

Choose an instance with the highest vCPU count

Answer

Choose an instance with the most memory available

Question 7

A company runs SAP S/4HANA on AWS and needs to back up the SAP HANA database to Amazon S3. They want to automate backups and ensure they are encrypted at rest. Which solution should they use?

Accepted Answer

Configure SAP HANA Backint agent to back up directly to S3 with SSE-S3 encryption. SAP HANA backup to S3 can be done using the hdbbackint interface with the SAP HANA Backint agent for S3, which supports encryption. Option A is wrong because AWS Backup does not directly integrate with hdbbackint. Option B is wrong because S3 lifecycle does not handle backups. Option D is wrong because AWS KMS alone does not perform backups.

Answer

Use AWS Backup to schedule backups to S3

Answer

Use an S3 lifecycle policy to transition backups to S3

Answer

Use AWS KMS to encrypt backups and store them manually

Question 8

An organization is deploying a large SAP HANA system on AWS. They need to ensure that the EBS volumes for the /hana/data and /hana/log directories are configured with optimal performance and resilience. Which configuration should they use?

Accepted Answer

Use io2 Block Express volumes with /hana/data on a RAID 0 set and /hana/log on a RAID 1 set. SAP HANA on AWS requires /hana/data and /hana/log to be on separate EBS volumes. Using io2 Block Express volumes with RAID 0 for data and RAID 1 for log is recommended. Option A is wrong because gp3 may not provide enough IOPS. Option B is wrong because /hana/log should be on separate volumes from /hana/data. Option D is wrong because /hana/data should use RAID 0 for performance.

Answer

Use io2 Block Express volumes with /hana/data on a RAID 1 set and /hana/log on a RAID 0 set

Answer

Use a single large gp3 EBS volume for both /hana/data and /hana/log

Answer

Use io2 Block Express volumes with /hana/data on one volume and /hana/log on another, no RAID

Question 9

A company runs SAP NetWeaver on AWS and notices that the application server is experiencing high CPU utilization during peak hours. They need to scale out the SAP application tier. What is the best approach?

Accepted Answer

Use an Auto Scaling group to automatically launch additional application servers and register them with the SAP application load balancer. Adding more SAP application servers (ASCS) behind an Application Load Balancer distributes load and provides HA. Option A is wrong because vertical scaling is limited. Option B is wrong because ASG alone does not register with SAP load balancer. Option C is wrong because launching manually is not automated.

Answer

Use AWS Global Accelerator to distribute traffic

Answer

Increase the instance size of the existing application server

Answer

Manually launch additional EC2 instances and configure them as application servers

Question 10

Which TWO actions are recommended for securing an SAP system on AWS? (Choose TWO.)

Accepted Answer

Enable encryption at rest for EBS volumes and RDS instances. Using security groups to control traffic and enabling encryption at rest are key security measures. Option B is wrong because public subnets are not recommended. Option D is wrong because disabling CloudTrail reduces visibility. Option E is wrong because default VPC security groups are too permissive.

Answer

Disable AWS CloudTrail to reduce logging overhead

Answer

Place all SAP servers in a public subnet for easier management

Answer

Use the default VPC security group for all SAP instances

Question 11

Which THREE factors should be considered when sizing an EC2 instance for SAP HANA? (Choose THREE.)

Accepted Answer

Total memory available on the instance. SAP HANA certification, memory requirements, and vCPU/network performance are key. Option D is wrong because instance store is not persistent. Option E is wrong because GPU is not required for most SAP HANA workloads.

Answer

GPU acceleration for HANA calculations

Answer

Instance store availability for HANA data

Question 12

Which TWO configurations are mandatory for an SAP HANA system replication setup on AWS? (Choose TWO.)

Accepted Answer

A virtual IP (VIP) address for the HANA system. SAP HANA system replication requires a virtual IP address and a replication network. Option B is wrong because a load balancer is optional. Option C is wrong because a separate VPC is not required. Option E is wrong because encryption is recommended but not mandatory.

Answer

An Application Load Balancer in front of the HANA instances

Answer

Encryption of data in transit using SSL

Answer

A separate VPC for the secondary instance

Question 13

A company is running SAP on AWS and needs to back up their SAP HANA database daily. The backup must be stored cost-effectively and retained for 7 years for compliance. Which AWS service should be used for long-term backup storage?

Accepted Answer

Amazon S3 Glacier Deep Archive. Option B is correct because S3 Glacier Deep Archive is the most cost-effective storage class for long-term retention of backups. Option A is wrong because S3 Standard is too expensive for 7-year retention. Option C is wrong because EBS Snapshots are not designed for long-term archival and have higher cost. Option D is wrong because S3 One Zone-IA is not suitable for long-term retention due to lower durability and potential data loss in case of facility failure.

Answer

Amazon S3 One Zone-IA

Answer

Amazon S3 Standard

Answer

Amazon EBS Snapshots

Question 14

An SAP administrator notices that the SAP application server is experiencing high latency when reading from the shared /sapmnt directory mounted from an Amazon EFS file system. The EFS file system is in General Purpose performance mode and uses Bursting throughput mode. The administrator checks CloudWatch metrics and sees that BurstCreditBalance is near zero. What is the most cost-effective solution to address the latency?

Accepted Answer

Enable Provisioned Throughput mode on the EFS file system. Option D is correct because switching to Provisioned Throughput mode ensures consistent throughput without relying on burst credits. Option A is wrong because switching to Max I/O performance mode does not increase throughput. Option B is wrong because EBS gp3 volumes are not shared across instances. Option C is wrong because increasing burst credit balance is not possible; burst credits are earned based on storage size.

Answer

Increase the size of the EFS file system to increase the burst credit balance

Answer

Mount the /sapmnt directory from an Amazon EBS gp3 volume instead

Answer

Change the EFS performance mode to Max I/O

Question 15

A company is planning to migrate their SAP system to AWS. They need to ensure that the SAP application servers and database servers are in the same AWS Region but in different Availability Zones for high availability. The network latency between Availability Zones must be minimal. Which AWS service should be used to connect the instances?

Accepted Answer

Use the default VPC network within the same VPC spanning multiple Availability Zones. Option A is correct because AWS uses a redundant, high-bandwidth, low-latency network between Availability Zones. Option B is wrong because VPC Peering is used for connecting different VPCs. Option C is wrong because Direct Connect is for on-premises connections. Option D is wrong because Transit Gateway is for hub-and-spoke connectivity, not needed for within a VPC.

Answer

Set up VPC Peering between the Availability Zones

Answer

Establish an AWS Direct Connect connection

Answer

Use AWS Transit Gateway to connect the subnets
