The optimal approach to ensure low-latency and high-throughput network performance in an SAP HANA scale-out design is to strategically utilize placement groups. Creating a cluster placement group for instances will ensure they are grouped within the same low-latency network zone in a single data center, which significantly boosts network performance by reducing inter-node latency. This targeted configuration is paramount when scaling SAP HANA, as node-to-node communication speed is crucial for database efficiency and reliability in large-scale deployments.

Question #12
A company needs to migrate its critical SAP workloads from an on-premises data center to AWS. The company has a few source production databases that are 10 TB or more in size. The company wants to minimize the downtime for this migration.
As part of the proof of concept, the company used a low-speed, high-latency connection between its data center and AWS. During the actual migration, the company wants to maintain a consistent connection that delivers high bandwidth and low latency. The company also wants to add a layer of connectivity resiliency. The backup connectivity does not need to be as fast as the primary connectivity.
An SAP solutions architect needs to determine the optimal network configuration for data transfer. The solution must transfer the data with minimum latency.
Which configuration will meet these requirements?
  1. A
    Set up one AWS Direct Connect connection for connectivity between the on-premises data center and AWS. Add an AWS Site-to-Site VPN connection as a backup to the Direct Connect connection.
  2. B
    Set up an AWS Direct Connect gateway with multiple Direct Connect connections that use a link aggregation group (LAG) between the on-premises data center and AWS.
  3. C
    Set up Amazon Elastic File System (Amazon EFS) file system storage between the on-premises data center and AWS. Configure a cron job to copy the data into this EFS mount. Access the data in the EFS file system from the target environment.
  4. D
    Set up two redundant AWS Site-to-Site VPN connections for connectivity between the on-premises data center and AWS.

Correct Answer:
D
chatbot-img GPT-4o - Answer
For a critical SAP workload migration with the need for minimum latency and high bandwidth, while ensuring connectivity resiliency, employing two redundant AWS Site-to-Site VPN connections is indeed effective. This setup offers the requisite robustness and redundancy for critical operations, ensuring continued service even if one VPN fails, while still facilitating the necessary data bandwidth and reduced latency. This alternative is particularly useful where Direct Connect may not be feasible due to various constraints, such as availability or cost, thereby aligning well with both primary and backup connectivity requirements.

Question #13
A company wants to migrate its SAP ERP landscape to AWS. The company will use a highly available distributed deployment for the new architecture. Clients will access SAP systems from a local data center through an AWS Site-to-Site VPN connection that is already in place. An SAP solutions architect needs to design the network access to the SAP production environment.
Which configuration approaches will meet these requirements? (Choose two.)
  1. A
    For the ASCS instance, configure an overlay IP address that is within the production VPC CIDR range. Create an AWS Transit Gateway. Attach the VPN to the transit gateway. Use the transit gateway to route the communications between the local data center and the production VPC. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
  2. B
    For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create an AWS Transit Gateway. Attach the VPN to the transit gateway. Use the transit gateway to route the communications between the local data center and the production VPC. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
  3. C
    For the ASCS instance, configure an overlay IP address that is within the production VPC CIDR range. Create a target group that points to the overlay IP address. Create a Network Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
  4. D
    For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create a target group that points to the overlay IP address. Create a Network Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
  5. E
    For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create a target group that points to the overlay IP address. Create an Application Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.

Correct Answer:
BE
chatbot-img GPT-4o - Answer
Fashioning an optimal SAP ERP migration configuration on AWS demands leveraging specific AWS resources adeptly. Utilizing an overlay IP address outside the production VPC CIDR range enhances network organization by offsetting the SAP system from standard traffic channels. Integrating a Transit Gateway streamlines the routing between the local data center and AWS, efficiently handling the layered communication needs typical to SAP environments. However, for SAP system traffic management, a Network Load Balancer is essential, not an Application Load Balancer, given the NAT compatibility and high-performance capabilities required for connection-intensive SAP applications.

Question #14
A company is running an SAP HANA database on AWS. The company is running AWS Backint Agent for SAP HANA (AWS Backint agent) on an Amazon EC2 instance. AWS Backint agent is configured to back up to an Amazon S3 bucket. The backups are failing with an AccessDenied error in the AWS Backint agent log file.
What should an SAP basis administrator do to resolve this error?
  1. A
    Assign execute permissions at the operating system level for the AWS Backint agent binary and for AWS Backint agent.
  2. B
    Assign an IAM role to an EC2 instance. Attach a policy to the IAM role to grant access to the target S3 bucket.
  3. C
    Assign the correct Region ID for the S3BucketAwsRegion parameter in AWS Backint agent for the SAP HANA configuration file.
  4. D
    Assign the value for the EnableTagging parameter in AWS Backint agent for the SAP HANA configuration file.

Correct Answer:
C
chatbot-img GPT-4o - Answer
The AccessDenied error typically occurs due to insufficient permissions for the AWS Backint agent on the EC2 instance trying to access the S3 bucket. To rectify this issue, the administrator should check and update the IAM role associated with the EC2 instance. It's important that this IAM role includes policies granting necessary permissions to access the relevant S3 bucket. Double-checking the instances' IAM roles and adjusting policies can resolve the error, enabling successful backups. Hence, while updating the region ID might seem correct, ensuring proper IAM permissions stands out as the more immediate and effective solution.

Question #15

These teams include procurement, finance, sales, and human resources. An SAP solutions architect has started designing this new landscape and the AWS account structures.
The company wants to use automation as much as possible. The company also wants to secure the environment, implement federated access to accounts, centralize logging, and establish cross-account security audits. In addition, the company’s management team needs to receive a top-level summary of policies that are applied to the AWS accounts.
What should the SAP solutions architect do to meet these requirements?
  1. A
    Use AWS CloudFormation StackSets to apply SCPs to multiple accounts in multiple Regions. Use an Amazon CloudWatch dashboard to check the applied policies in the accounts.
  2. B
    Use an AWS Elastic Beanstalk blue/green deployment to create IAM policies and apply them to multiple accounts together. Use an Amazon CloudWatch dashboard to check the applied policies in the accounts.
  3. C
    Implement guardrails by using AWS CodeDeploy and AWS CodePipeline to deploy SCPs into each account. Use the CodePipeline deployment dashboard to check the applied policies in the accounts.
  4. D
    Apply SCPs through AWS Control Tower. Use the AWS Control Tower integrated dashboard to check the applied policies in the accounts.

Correct Answer:
D
