Amazon PAS-C01 Exam Dumps

Option B is correct because it uses AWS Direct Connect gateway with multiple Direct Connect connections that use a link aggregation group (LAG) between the on-premises data center and AWS. This provides high availability and redundancy for the network connection, as well as increased bandwidth and lower latency. It also allows the use of an overlay IP address that is outside the production VPC CIDR range for the ASCS instance, which is recommended by SAP for high availability.

Option D is correct because it uses two redundant AWS Site-to-Site VPN connections for connectivity between the on-premises data center and AWS. This provides a backup connection in case one of the VPN connections fails. It also allows the use of an overlay IP address that is outside the production VPC CIDR range for the ASCS instance, which is recommended by SAP for high availability.

Option A is incorrect because it uses an overlay IP address that is within the production VPC CIDR range for the ASCS instance, which is not recommended by SAP for high availability. It also uses only one AWS Direct Connect connection, which does not provide redundancy or load balancing for the network connection.

Option C is incorrect because it uses Amazon Elastic File System (Amazon EFS) file system storage between the on-premises data center and AWS, which is not a network configuration for data transfer. It also uses an Application Load Balancer, which does not support TCP protocol for the ASCS instance.

Option E is incorrect because it uses an Application Load Balancer, which does not support TCP protocol for the ASCS instance. It also uses a target group that points to the overlay IP address, which is not necessary for the network access to the ASCS instance.

SAP software is secured by a license using a hardware key (customer key). As described in SAP note 174911,'' this hardware key is based upon a MAC address of a network card in your Linux system''. In certain situations the algorithm can pick a different network card than it used for calculation before, thus returning a different hardware key.

The change in hypervisor from Xen to Nitro may be the cause of the hardware ID change. https://docs.aws.amazon.com/sap/latest/general/overview-sap-on-aws.html#:~:text=SAP%20Note%202113263,AWS%20Hardware%20ID

A is correct because ensuring that the SAP kernel versions are 7.45 or later is required to support IMDSv2 only. SAP kernel versions below 7.45 do not support IMDSv2 and will fail to start if IMDSv1 is disabled. The other options are not relevant for the security enhancement and may create an SAP outage.

gp2 and gp3 volumes balance price and performance for a variety of workloads, while io1, io2, and io2 Block Express volumes provide the highest performance for mission-critical applications. From these options, you can choose the best storage solution that meets your performance and cost requirements. We recommend the io2 or io2 Block Express configuration for mission-critical SAP HANA production workloads.
