PAS-C01 Design of SAP Workloads on AWS Practice Test 10 — 15 Questions

Question 1

A company is running SAP on AWS and wants to use a custom AMI for SAP application servers. They need to ensure that the AMI is encrypted using AWS KMS. Which step is required to launch encrypted instances from this AMI?

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

Accepted Answer

Copy the AMI and specify a KMS key for encryption.. To launch encrypted instances from an unencrypted custom AMI, you must first copy the AMI and specify a KMS key for encryption during the copy process. This creates an encrypted AMI that can then be used to launch encrypted instances. AWS does not allow you to directly encrypt an existing AMI in place; the copy operation is the required mechanism.

Answer

Use an AWS Marketplace AMI that is already encrypted.

Answer

Use the AWS Management Console to modify the AMI to enable encryption.

Answer

Specify the KMS key ID in the run-instances command.

Question 2

Which TWO statements are correct regarding SAP HANA backup strategies on AWS? (Choose two.)

Accepted Answer

S3 can be used as a backup destination for SAP HANA using AWS Backup.. AWS Backup natively supports SAP HANA as a managed backup service, allowing backups to be stored directly in Amazon S3. This provides a durable, scalable, and cost-effective backup destination without the need to manage backup infrastructure or scripts. Option B is correct because AWS Backup integrates with SAP HANA to automate full, incremental, and differential backups to S3.

Answer

EBS snapshots are the most cost-effective option for long-term backup retention.

Answer

S3 Standard-IA storage class is optimal for cross-region replication.

Answer

SAP HANA backup to EBS volumes is the recommended method for long-term archival.

Question 3

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

Accepted Answer

The instance must have enough memory to fit the HANA database.. SAP HANA is an in-memory database that loads the entire dataset into RAM for processing. The EC2 instance must have sufficient memory to accommodate the HANA database size, including overhead for system tables and temporary data, as specified in the SAP HANA memory sizing guidelines.

Answer

The instance should have GPU accelerators for faster query processing.

Answer

The instance must have local instance store volumes for data persistence.

Question 4

Which TWO AWS services can be used to monitor SAP system performance and send alerts? (Choose two.)

Accepted Answer

Amazon Simple Notification Service (SNS). Amazon CloudWatch is the primary AWS monitoring service that can collect metrics from SAP systems (e.g., via SAP Cloud Connector or custom scripts) and trigger alarms based on thresholds. Amazon SNS is the notification service that CloudWatch alarms use to send alerts via email, SMS, or HTTP endpoints. Together, they form the standard monitoring and alerting pipeline for SAP workloads on AWS.

Question 5

A company is migrating its SAP HANA database to AWS and needs to choose the most appropriate EC2 instance type. The workload requires high memory bandwidth and is CPU-intensive. Which instance family would best meet these requirements?

Accepted Answer

X1e instance family. The X1e instance family is purpose-built for high-memory, CPU-intensive SAP HANA workloads, offering up to 3.9 TB of memory and high memory bandwidth per vCPU. This aligns with SAP HANA's requirement for large in-memory databases and compute-intensive processing, making D the correct choice.

Answer

M5 instance family

Answer

I3 instance family

Answer

C5 instance family

Question 6

An SAP Basis administrator notices that the SAP application server on an EC2 instance is experiencing intermittent high latency when writing to the SAP HANA database. The HANA database is on a separate EC2 instance in the same VPC and Availability Zone. Which configuration change is most likely to resolve the issue?

Accepted Answer

Enable Jumbo Frames on the network interfaces. The intermittent high latency when writing to SAP HANA is likely caused by network packet fragmentation. Enabling Jumbo Frames (MTU 9001) on the network interfaces of both the SAP application server and the HANA database EC2 instances reduces the number of packets required for large data transfers, lowers CPU overhead for packet processing, and improves throughput. This is a standard recommendation for SAP on AWS to optimize network performance between application and database layers.

Answer

Launch the instances in a cluster placement group

Answer

Enable EBS optimization on both instances

Answer

Change the Elastic Network Adapter (ENA) to SR-IOV

Question 7

A company is designing a highly available SAP NetWeaver system on AWS. They plan to use a two-node ASCS/ERS cluster with SUSE Linux Enterprise Server (SLES). Which AWS service is required to manage the virtual IP address for the cluster?

Accepted Answer

Amazon Route 53. Amazon Route 53 is required to manage the virtual IP address for the two-node ASCS/ERS cluster by using DNS failover. In a SLES-based SAP NetWeaver cluster on AWS, the cluster software (e.g., Pacemaker) updates a Route 53 DNS record with the private IP address of the active node, enabling clients to connect via a hostname that resolves to the current primary node. This DNS-based approach replaces traditional virtual IP (VIP) floating, which is not natively supported in AWS VPC due to the lack of gratuitous ARP or multicast.

Answer

AWS VPC Peering

Answer

Amazon EBS

Answer

Elastic Load Balancing

Question 8

An SAP administrator is troubleshooting a performance issue on an SAP HANA database running on an r5.24xlarge instance. The database is I/O bound during high load periods. The administrator has already verified that the EBS volumes are not saturated. What should the administrator check next?

Accepted Answer

Check the Elastic Network Adapter (ENA) settings and consider tuning the ring buffer size. On an r5.24xlarge instance, EBS optimization is always enabled by default, so verifying it again is unnecessary. The issue is I/O bound during high load, but EBS volumes are not saturated, indicating the bottleneck is likely at the network layer. The Elastic Network Adapter (ENA) ring buffer size can become overwhelmed under high network traffic, causing packet drops and increased latency, which manifests as I/O wait. Tuning the ring buffer size (e.g., using `ethtool -G eth0 rx 4096 tx 4096`) can reduce drops and improve throughput for SAP HANA's network-intensive operations.

Answer

Verify that EBS optimization is enabled

Answer

Increase the SWAP space on the instance

Answer

Upgrade to a compute-optimized instance like c5.24xlarge

Question 9

A company is implementing SAP S/4HANA on AWS and wants to ensure that the system is backed up properly. They need to back up the HANA database and the application layer. Which approach is recommended for backing up the HANA database?

Accepted Answer

Use the AWS Backint agent to back up HANA to Amazon S3. The AWS Backint agent is the recommended and supported method for backing up SAP HANA databases on AWS. It integrates directly with SAP HANA's native backup interface (backint for SAP HANA) to stream backup data to Amazon S3, ensuring consistent, incremental, and catalog-aware backups without relying on file-system-level snapshots.

Answer

Use EBS snapshots for the HANA data volumes

Answer

Configure an S3 lifecycle policy to archive the HANA log files

Answer

Use AWS Backup with a backup plan that includes the HANA instance

Question 10

An SAP administrator needs to migrate an on-premises SAP HANA system to AWS. The total size of the HANA data and log volumes is 5 TB. The administrator wants to minimize downtime and use the fastest possible initial data transfer method. Which approach should they use?

Accepted Answer

Use AWS Snowball Edge to physically ship the data. AWS Snowball Edge provides a physical data transfer device that can be shipped to the on-premises site, loaded with the 5 TB of SAP HANA data and log volumes, and then shipped back to AWS for ingestion into an S3 bucket. This approach offers the fastest initial transfer for large datasets (multi-TB) over a WAN, as it bypasses network bandwidth limitations entirely, minimizing downtime compared to internet-based or dedicated network transfers.

Answer

Use Amazon S3 Transfer Acceleration to upload the data over the internet

Answer

Use AWS Direct Connect to transfer the data over a dedicated network connection

Answer

Use VPC Peering to connect on-premises to AWS and copy data

Question 11

A company is running SAP ERP on AWS and is experiencing high costs due to underutilized EC2 instances. The SAP system is non-production and can tolerate interruptions. Which approach would most cost-effectively reduce costs without compromising the ability to resume operations quickly?

Accepted Answer

Use EC2 Spot Instances for the application servers and configure them to be terminated gracefully. EC2 Spot Instances offer significant cost savings (up to 90% compared to On-Demand) for fault-tolerant, non-production SAP workloads. By configuring graceful termination (e.g., using lifecycle hooks or AWS Systems Manager to drain SAP application server connections before the instance is interrupted), the system can resume quickly when capacity becomes available again, meeting the requirement for cost reduction without compromising rapid recovery.

Answer

Purchase Reserved Instances for the current usage to get a discount

Answer

Increase the instance size to improve performance and reduce runtime

Answer

Use Dedicated Hosts to reduce licensing costs

Question 12

An SAP administrator is setting up a new SAP HANA system on AWS and needs to ensure that the system can recover from an Availability Zone failure. Which strategy should they implement for high availability?

Accepted Answer

Set up HANA System Replication across two Availability Zones. HANA System Replication (HSR) is the native SAP mechanism for achieving high availability across Availability Zones (AZs). By replicating data synchronously or synchronously in-memory to a standby instance in a different AZ, it ensures automatic failover with minimal data loss in the event of an AZ failure. This directly meets the requirement for recovery from an AZ failure without relying on storage-level or database-agnostic approaches.

Answer

Attach multiple Elastic Network Interfaces (ENIs) to the HANA instance

Answer

Configure the HANA database with Amazon RDS Multi-AZ

Answer

Take EBS snapshots every hour and restore in another AZ

Question 13

A company is deploying a mission-critical SAP S/4HANA system on AWS. They need to ensure the highest level of availability and minimize data loss. Which TWO strategies should they implement? (Choose two.)

Accepted Answer

Set up HANA System Replication in synchronous mode across two Availability Zones. HANA System Replication in synchronous mode ensures that every committed transaction is written to the primary and replicated to a secondary HANA instance before the commit is acknowledged. This provides near-zero data loss (RPO=0) and, combined with automatic failover, supports high availability across Availability Zones.

Answer

Use EC2 Spot Instances for the primary application server

Answer

Configure automated EBS snapshots every 5 minutes

Answer

Use Amazon RDS Multi-AZ for the HANA database

Question 14

An SAP administrator is designing a backup strategy for an SAP HANA database on AWS. They want to use the Backint interface with Amazon S3. Which THREE components are required? (Choose three.)

Accepted Answer

IAM role with permissions to write to the S3 bucket. The Backint interface for SAP HANA on AWS requires an IAM role that grants the AWS Backint Agent permissions to write backup data to the designated S3 bucket. Without this IAM role, the agent cannot authenticate or perform PutObject operations against S3, making the backup fail.

Answer

EBS volumes for the backup catalog

Answer

S3 Transfer Acceleration enabled

Question 15

A company is planning to migrate its SAP landscape to AWS. They want to use AWS services to reduce operational overhead. Which TWO services can help automate the deployment and configuration of SAP systems? (Choose two.)

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP is correct because it provides a guided, step-by-step process to size, configure, and deploy SAP systems on AWS, automatically provisioning the necessary EC2 instances, storage, and networking. It reduces operational overhead by automating the deployment and initial configuration of SAP landscapes, including HANA databases and NetWeaver applications.
