Question 2

An SAP Basis administrator needs to apply security patches to the operating system of SAP EC2 instances. The administrator wants to use AWS Systems Manager Patch Manager. Which THREE steps are required to set up patching? (Choose THREE.)

Accepted Answer

Create a patch baseline in AWS Systems Manager.. To set up patching with AWS Systems Manager Patch Manager, you need three steps: Create a patch baseline (A) to define which patches to apply. Install the SSM Agent on each EC2 instance (C) to allow Systems Manager to communicate with the instances. Associate the instances with a maintenance window (E) to schedule when patching occurs. Options B and D are not required: Lambda is not needed because Patch Manager handles the patching process, and CloudWatch Logs are not mandatory for patching operations.

Answer

Create an AWS Lambda function to invoke the patching process.

Answer

Configure Amazon CloudWatch Logs to store patch logs.

Question 3

A company is migrating an SAP BusinessObjects environment to AWS. The migration must ensure that the legacy reporting system remains accessible during the transition. Which AWS service can help facilitate this by allowing the company to redirect traffic gradually?

Accepted Answer

Amazon Route53 with weighted routing policies. Amazon Route53 with weighted routing policies can gradually shift traffic from on-premises to AWS by assigning weights to DNS records. Option A (Amazon CloudFront) is a content delivery network, not for traffic shifting. Option B (Elastic Load Balancer) distributes traffic within AWS, not for gradual migration. Option C (AWS Global Accelerator) improves performance but does not provide weighted routing. Option D (Amazon Route53 with weighted routing policies) is correct because it allows incremental traffic redirection during migration.

Answer

Amazon CloudFront

Answer

Elastic Load Balancer (ELB)

Answer

AWS Global Accelerator

Question 4

A company is migrating an SAP ERP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS). The company plans to use a shared file system for the SAP transport directory. Which TWO AWS services can be used to provide a highly available shared file system for this purpose?

Accepted Answer

Amazon FSx for NetApp ONTAP. Options D (Amazon FSx for NetApp ONTAP) and E (Amazon EFS) are correct because they provide NFS-based shared file systems that support the required protocols for SAP transport directory and can be configured for high availability. Option A (Amazon EBS Multi-Attach) is block storage, not a shared file system, and does not support concurrent read/write operations required for SAP. Option B (Amazon S3) is object storage, not POSIX-compliant. Option C (Amazon FSx for Windows File Server) uses SMB protocol, not NFS, which is required by SAP.

Answer

Amazon EBS Multi-Attach

Answer

Amazon S3

Answer

Amazon FSx for Windows File Server

Question 5

A company is planning to migrate its SAP NetWeaver system from on-premises to AWS. The system uses an SAP HANA database. The company wants to use the SAP System Migration (sum) tool. Which THREE prerequisites must be met before starting the migration?

Accepted Answer

The target SAP HANA database must be installed and running.. For an SAP System Migration (SUM) to AWS with HANA, the target HANA database must be installed and running (A), the target system must have the SAP kernel and required libraries (B), and source and target must be on the same OS (D) to ensure compatibility. HTTP proxy (C) is not a prerequisite; communication between source and target does not require a proxy. The source system does not need to be fully shut down before starting; SUM can be run with the source system running (E).

Answer

An HTTP proxy must be configured for communication between source and target.

Answer

The source SAP system must be fully shut down before starting the migration.

Question 6

A company is migrating a critical application to AWS and needs to ensure compliance with PCI DSS. The application handles credit card numbers. Which AWS service should be used to encrypt the data at rest?

Accepted Answer

AWS CloudHSM. AWS CloudHSM, is correct because it provides dedicated hardware security modules (HSMs) that are FIPS 140-2 Level 3 compliant, which is often required for PCI DSS compliance when handling credit card numbers. Option A (Amazon S3 server-side encryption) is incorrect because it is used for encrypting objects in S3 and does not provide dedicated HSM capabilities. Option B (AWS KMS) is a managed key service but is FIPS 140-2 Level 2 only, which may not meet the stringent requirements of PCI DSS for protecting cardholder data. Option D (AWS Secrets Manager) is incorrect because it manages secrets such as database credentials, not encryption keys for data at rest.

Answer

Amazon S3 server-side encryption

Answer

AWS Key Management Service (KMS)

Answer

AWS Secrets Manager

Question 7

A company is migrating an SAP S/4HANA system to AWS. The system requires high availability across two Availability Zones. Which AWS service should be used to attach a block-level storage volume that can be concurrently accessed by two EC2 instances in active/passive mode?

Accepted Answer

Use Amazon FSx for NetApp ONTAP to provide a shared block storage volume accessible from both AZs.. Amazon FSx for NetApp ONTAP provides a shared block-level storage volume that can be concurrently accessed by multiple EC2 instances across different Availability Zones using the iSCSI protocol. In an active/passive SAP S/4HANA setup, this allows the passive instance to mount the same storage volume and take over if the active instance fails, meeting the high-availability requirement across two AZs.

Answer

Question 10

An SAP ERP system on AWS is experiencing performance degradation. A review shows that the Amazon EBS volumes used for SAP transport directories are gp2 with high throughput but high latency. The SAP team needs improved I/O performance without changing the total storage capacity. Which action should be taken?

Accepted Answer

Change the volume type to io2 Block Express with provisioned IOPS.. Io2 Block Express volumes provide consistent, high-performance IOPS with sub-millisecond latency, which directly addresses the high-latency issue with gp2 volumes. This option improves I/O performance without changing storage capacity, as required by the SAP team. gp2 volumes suffer from burst bucket limitations, leading to high latency under sustained throughput, while io2 Block Express offers provisioned IOPS for predictable performance.

Answer

Change the volume type to gp3 and increase baseline IOPS.

Answer

Move the transport directories to instance store volumes.

Answer

Enable EBS throughput optimization on the EC2 instance.

Question 11

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 12

A company is implementing an SAP S/4HANA system on AWS. The system must be highly available across multiple Availability Zones. Which of the following strategies should the company implement for the SAP Central Services (ASCS) instance to meet high availability requirements?

Accepted Answer

Deploy a Pacemaker cluster with two EC2 instances across Availability Zones using a shared file system.. SAP Central Services (ASCS) requires a highly available cluster that can manage the Enqueue and Message Server processes. A Pacemaker cluster across two Availability Zones, using a shared file system (e.g., Amazon EFS or a replicated file system), provides the necessary fencing, resource monitoring, and failover for ASCS. This architecture ensures that if the primary ASCS instance fails, the secondary instance in the other AZ can take over with minimal downtime, meeting the high availability requirement.

Answer

Deploy a single EC2 instance with a large instance type to handle failover.

Answer

Configure SAP HANA System Replication between two Availability Zones.

Answer

Use Amazon RDS for SAP Central Services with Multi-AZ deployment.

Question 13

A company is migrating an SAP system to AWS and wants to use AWS Systems Manager for patching. The SAP application server is running Windows. What is a prerequisite for Systems Manager to manage the instance?

Accepted Answer

Install the AWS Systems Manager Agent (SSM Agent) on the instance. AWS Systems Manager requires the SSM Agent to be installed and running on managed instances to perform patching and other management operations. The SSM Agent processes Systems Manager requests, executes run commands, and reports instance state back to the Systems Manager service. Without the agent, the instance cannot communicate with the Systems Manager endpoint or receive patching instructions.

Answer

Install the Amazon CloudWatch agent on the instance

Answer

Enable AWS Config on the instance

Answer

Assign a public IP address to the instance

Question 14

A company is running a critical SAP application on SAP HANA in an AWS Single-AZ deployment. The application has experienced downtime twice in the last month due to underlying hardware failures. What is the MOST cost-effective solution to minimize future downtime without compromising performance?

Accepted Answer

Deploy the SAP HANA database in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones.. Deploying SAP HANA in a Multi-AZ configuration using SAP HANA System Replication (HSR) across Availability Zones provides synchronous replication and automatic failover in case of hardware failure. This minimizes downtime without requiring a larger instance or manual intervention, and maintains performance by using the same instance type and storage configuration as the primary.

Answer

Move the SAP HANA instance to a larger instance type to improve hardware reliability.

Answer

Use Dedicated Hosts to ensure physical isolation from other AWS customers.

Answer

Implement automated snapshots of the SAP HANA data volume and restore in case of failure.

Question 15

A company needs to migrate a large amount of on-premises data to Amazon S3. The data is stored on tape backups. The migration must be completed within 2 weeks. Which AWS service should they use?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a physical device designed for large-scale data transfers when network bandwidth is limited or transfer time is critical. For migrating petabytes of tape backup data to Amazon S3 within 2 weeks, Snowball Edge provides a cost-effective and fast solution by shipping physical storage devices. Option A (AWS DataSync) is an online data transfer service, but for large tape backups, the transfer may take longer than 2 weeks over typical internet connections. Option B (AWS Database Migration Service) is specifically for migrating databases, not tape file data. Option D (AWS Storage Gateway) provides hybrid cloud storage but is not optimized for bulk one-time migration of tape archives.

Answer

AWS DataSync

Answer

AWS Database Migration Service

Answer

AWS Storage Gateway

Question 16

A company is running SAP S/4HANA on AWS with a scale-out HANA configuration. The system is experiencing performance degradation during peak hours. Monitoring shows high network throughput on the HANA nodes. Which EC2 instance family is best suited to mitigate this?

Accepted Answer

x2iedn instances with high network bandwidth.. The x2iedn instances are specifically designed for SAP HANA scale-out configurations, offering high memory per vCPU and dedicated high network bandwidth via the Elastic Network Adapter (ENA). In a scale-out HANA setup, nodes communicate intensively over the network for data synchronization and shared storage access, so high network throughput directly mitigates the performance degradation during peak hours.

Answer

c5 instances with placement groups.

Answer

r5 instances with enhanced networking.

Answer

m5 instances with EBS optimization.

Question 17

An organization is migrating a multi-tier application to AWS. The web tier runs on EC2 instances behind an Application Load Balancer. The database tier uses a self-managed MySQL instance on EC2. To achieve high availability, they plan to use Multi-AZ deployment. Which migration step should they prioritize to ensure minimal downtime?

Accepted Answer

Set up continuous replication using DMS and perform a cutover. Setting up continuous replication using AWS DMS (Database Migration Service) ensures data is synchronized between the source and target databases with minimal lag. This allows a quick cutover, significantly reducing downtime during migration. Option A is correct. Option B is not prioritized for minimal downtime as snapshots require downtime to restore. Option C is wrong because a one-time full load alone would miss ongoing changes, causing data loss. Option D defeats the high-availability goal by not using Multi-AZ from the start.

Answer

Configure Amazon EBS snapshots for the database volume

Answer

Use AWS DMS for one-time full load only

Answer

Launch the database in a single Availability Zone first

Question 18

A company is designing an SAP environment on AWS and needs to ensure high availability for SAP HANA. Which TWO AWS services or features are commonly used to achieve this? (Choose TWO.)

Accepted Answer

Amazon Route 53 with failover routing. Amazon Route 53 with failover routing is correct because it allows DNS-based routing to redirect traffic to a secondary SAP HANA instance in another Availability Zone if the primary fails. This is a common pattern for achieving high availability for SAP HANA on AWS, as it works in conjunction with SAP HANA system replication to provide automatic failover at the DNS level.

Answer

Amazon EFS with Multi-AZ mount targets

Answer

Amazon S3 cross-region replication

Answer

AWS Global Accelerator with endpoint weights

Question 19

A company runs its SAP HANA database on an EC2 instance with EBS volumes. The database requires consistent high IOPS and low latency. The system is currently using EBS gp2 volumes, but performance is inconsistent during peak loads. Which TWO steps should the administrator take to improve storage performance? (Choose 2)

Accepted Answer

Configure multiple EBS volumes in a RAID 0 stripe set.. Options C and D are correct. C: Configuring multiple EBS volumes in a RAID 0 stripe set increases throughput by combining I/O across volumes, which helps with peak loads. D: Migrating to EBS io2 Block Express volumes with provisioned IOPS ensures consistent high IOPS and low latency. A is incorrect because increasing gp2 volume size only raises baseline IOPS but does not guarantee consistent high IOPS during peak loads. B is incorrect because regular EBS snapshots do not improve performance and can degrade it during snapshot creation. E is incorrect because EBS-optimized instances are enabled by default for current generation instances and are not a storage performance improvement step.

Answer

Increase the size of the existing gp2 volumes to increase baseline IOPS.

Answer

Take regular EBS snapshots to improve performance.

Answer

Enable EBS-optimized on the EC2 instance.

Question 20

An SAP system on AWS is experiencing performance issues due to high I/O wait times on the database server. The database runs on an EC2 instance with EBS volumes. Which THREE actions can improve the I/O performance? (Choose THREE.)

Accepted Answer

Use instance store SSDs for the database logs. Instance store SSDs provide very low latency and high IOPS directly attached to the EC2 host, which is ideal for database log files that require frequent, synchronous writes. By offloading the logs from EBS to instance store, you reduce contention on the EBS volumes and improve overall I/O performance for the SAP database.

Answer

Reduce the volume size to increase the burst duration

Answer

Configure RAID 0 of multiple gp2 volumes
