PAS-C01 Practice Test 11 — 15 Questions

Question 1

A company is migrating an SAP ECC system to AWS and needs to ensure low-latency connectivity between the application server and the database server. Both servers will be in the same VPC but different subnets. Which configuration best minimizes latency?

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

Accepted Answer

Place the servers in the same placement group and the same Availability Zone. Placing both the SAP application server and database server in the same placement group and the same Availability Zone ensures they are physically close together within a single data center, minimizing network latency. This configuration leverages the low-latency, high-bandwidth network connectivity provided by a cluster placement group, which is critical for SAP ECC workloads that require rapid database transactions.

Answer

Place the servers in different placement groups but the same Availability Zone

Answer

Use a cluster placement group spanning two Availability Zones

Answer

Place the servers in different Availability Zones but within the same region

Question 2

An SAP Basis team is implementing SAP HANA system replication across two AWS Availability Zones. The HANA primary instance uses Provisioned IOPS SSD (io2) EBS volumes. The secondary instance must be kept in sync with minimal data loss. Which networking configuration is required to ensure low-latency, high-throughput replication traffic between the instances?

Accepted Answer

Enable Enhanced Networking (ENA) on both instances.. The correct configuration is to enable Enhanced Networking (ENA) on both instances. ENA provides high throughput and low latency for SAP HANA replication traffic across Availability Zones. ClassicLink is deprecated, VPN adds unnecessary latency, and VPC peering is not needed between subnets already in the same VPC. Cluster placement groups cannot span Availability Zones.

Answer

Use ClassicLink to connect the instances.

Answer

Set up a VPN connection between the instances.

Answer

Configure VPC peering between the two subnets.

Question 3

An SAP system on AWS is using a Multi-AZ deployment for high availability. The SAP Central Services (ASCS) and Enqueue Replication Server (ERS) are running on separate EC2 instances. During a failover test, the ASCS instance fails, but the ERS does not take over. What is the most likely cause?

Accepted Answer

The floating IP address is not configured to move to the ERS instance. In SAP on AWS Multi-AZ HA designs, the ASCS and ERS instances share a floating (virtual) IP address that must move from the failed ASCS to the ERS during failover, typically managed by a cluster agent (e.g., Pacemaker or SIOS LifeKeeper). If the floating IP is not configured to move, the ERS never takes over even though it is healthy — this is the most likely cause of the described failure.

Answer

The ERS instance does not have the required security group rules

Answer

The DNS TTL is set too high

Answer

The ERS instance is in a different subnet

Question 4

A company is migrating an SAP HANA database to AWS. The system requires a high-performance storage solution with low latency for database files, and the storage must be scalable without downtime. Which AWS storage solution should the company use for the SAP HANA data volume?

Accepted Answer

Amazon EBS io2 Block Express. Amazon EBS io2 Block Express is the correct choice because it provides up to 256,000 IOPS per volume with sub-millisecond latency, meeting SAP HANA's strict performance requirements for data volumes. It also supports Elastic Volumes, allowing you to scale storage capacity and performance without downtime, which is critical for production SAP HANA systems.

Answer

Amazon S3

Answer

Amazon EBS st1

Answer

Amazon EBS gp3

Question 5

A company is migrating SAP HANA to AWS and needs to ensure high availability. The database must be replicated synchronously across two Availability Zones with automatic failover. Which AWS service should be used?

Accepted Answer

SAP HANA System Replication (HSR) with Pacemaker. SAP HANA System Replication (HSR) with Pacemaker provides synchronous replication and automatic failover, making it the appropriate solution for high availability across Availability Zones. Amazon EBS Multi-Attach is incorrect because it is limited to a single AZ and not designed for SAP HANA replication. AWS DMS is for database migration, not ongoing HA. Amazon RDS Multi-AZ is for RDS databases and does not support SAP HANA.

Answer

Amazon EBS Multi-Attach volumes

Answer

AWS Database Migration Service (DMS)

Answer

Amazon RDS Multi-AZ deployment

Question 6

Which TWO of the following are valid strategies to improve the availability of an SAP HANA database on AWS?

Accepted Answer

Implement automatic failover using SAP HANA System Replication.. Option A is correct because SAP HANA System Replication (HSR) provides continuous replication of data from a primary to a secondary HANA system and, combined with a cluster manager such as Pacemaker or an AWS overlay IP, enables automatic failover so the standby takes over with minimal RTO/RPO. Option D is correct because deploying HSR across two Availability Zones places the primary and secondary nodes in physically separate data centers with independent power and networking, protecting against a full AZ outage while keeping replication synchronous or near-synchronous. Option B is not valid because Amazon RDS does not offer a HANA engine, so Multi-AZ for HANA is not a supported service. Option C is not a high-availability strategy: daily snapshots only provide point-in-time recovery with hours of potential data loss and long restore times, not continuous availability. Option E is not correct because scaling up the EC2 instance improves performance/capacity, not availability, and a single larger instance remains a single point of failure.

Answer

Use Amazon RDS for HANA with Multi-AZ deployment.

Answer

Take daily snapshots of the HANA data volume.

Answer

Use a larger EC2 instance type for the HANA server.

Question 7

An SAP system administrator needs to automate the patching of Amazon RDS for SAP ASE databases. Which AWS service can be used to schedule and apply database patches automatically?

Accepted Answer

Amazon RDS maintenance window. Amazon RDS maintenance window is a built-in feature that allows you to schedule automatic patching for RDS databases, including SAP ASE. It is the appropriate mechanism for automating patching. Options A (AWS OpsWorks) is for configuration management. Option C (AWS Systems Manager Maintenance Windows) can orchestrate tasks but cannot directly apply RDS patches; RDS manages patching internally. Option D (AWS Systems Manager Patch Manager) is designed for EC2 instances, not RDS.

Answer

AWS OpsWorks

Answer

AWS Systems Manager Maintenance Windows

Answer

AWS Systems Manager Patch Manager

Question 8

A company is designing an SAP system on AWS with SAP HANA as the database. The system must be highly available across multiple Availability Zones. Which TWO actions should the company take to meet this requirement?

Accepted Answer

Configure SAP HANA System Replication (HSR) in synchronous mode. Option A is correct because SAP HANA System Replication (HSR) in synchronous mode replicates data from the primary HANA instance to a secondary instance in another Availability Zone with zero data loss (RPO=0), which is the standard mechanism for HANA database high availability on AWS. Option D is correct because a Pacemaker cluster (typically with Corosync and a fencing/STONITH mechanism) automates the detection of a primary node failure and orchestrates the takeover of the HANA secondary, which is required for a true highly available, multi-AZ SAP HANA deployment. Option B is not appropriate because EBS snapshots are point-in-time backups with no continuous replication, so restoring in another AZ would incur significant RPO/RTO and does not provide automatic HA. Option C is incorrect because S3 cross-region replication is for object storage and is not a supported replication mechanism for live SAP HANA database files. Option E is incorrect because manual DNS failover is not automated, introduces human error and long recovery times, and does not satisfy a highly available multi-AZ design.

Answer

Perform periodic EBS snapshots and restore in another AZ

Answer

Use Amazon S3 cross-region replication for the database files

Answer

Use manual failover by changing DNS records

Question 9

A company is designing an SAP S/4HANA deployment on AWS with high availability. They want to use a shared file system for the SAP transport directory. Which AWS service should they use for this shared file system?

Accepted Answer

Amazon EFS. Amazon EFS is the correct choice because it provides a fully managed, POSIX-compliant, NFS-based shared file system that can be mounted concurrently by multiple EC2 instances across different Availability Zones, which is exactly what an SAP transport directory requires. The SAP transport directory (e.g., /usr/sap/trans) must be accessible from all SAP application servers in the high-availability cluster, and EFS supports the necessary file locking and consistency semantics for SAP's transport management system (TMS).

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with multi-attach enabled

Answer

Amazon S3

Question 10

A company is migrating its SAP ERP system to AWS and wants to use storage that offers the highest IOPS for the SAP HANA database. Which storage option should be used?

Accepted Answer

Provisioned IOPS SSD (io2) volumes. For SAP HANA databases on AWS, the highest IOPS is achieved using Provisioned IOPS SSD (io2) volumes, which are designed for latency-sensitive, I/O-intensive workloads. io2 volumes offer up to 256,000 IOPS per volume with 99.999% durability, making them the optimal choice for SAP HANA's demanding performance requirements.

Answer

General Purpose SSD (gp3) volumes

Answer

Instance Store volumes

Answer

Throughput Optimized HDD (st1) volumes

Question 11

A company is migrating its SAP environment to AWS using AWS Launch Wizard for SAP. Which TWO pieces of information does Launch Wizard require to deploy an SAP system? (Choose TWO.)

Accepted Answer

SAP product version (e.g., SAP S/4HANA 2020). Option A is correct because AWS Launch Wizard for SAP requires you to specify the SAP product and version (for example, SAP S/4HANA 2020 or SAP NetWeaver) so it can select the appropriate deployment pattern, sizing, and supported operating system and database combinations. Option E is correct because the SAP system ID (SID), a three-character identifier such as S4H, is mandatory for defining the SAP system's naming, directories, and instance configuration during deployment. Option B is not required; Launch Wizard does not ask for the number of SAP users, since sizing is driven by the selected SAP product, deployment size, and instance type choices. Option C is not required because on-premises IP addresses are irrelevant to a new AWS deployment; Launch Wizard works with the target VPC, subnets, and CIDR ranges you specify in AWS. Option D is not required because the AWS account ID is implicitly known from the credentials used to run Launch Wizard and is not an input field for the deployment.

Answer

Number of SAP users

Answer

On-premises IP addresses

Answer

AWS account ID

Question 12

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 13

A company is running SAP ERP on AWS and using a shared file system for the SAP transport directory. The file system must be accessible from multiple EC2 instances in different Availability Zones. Which AWS storage solution should be used?

Accepted Answer

Amazon EFS. Amazon EFS is a fully managed, scalable, elastic NFS file system that can be mounted on multiple EC2 instances across multiple Availability Zones within a region. It is ideal for shared file systems like the SAP transport directory, which must be accessible from multiple instances in different AZs. EFS provides the required cross-AZ accessibility and POSIX compliance.

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Answer

Amazon EBS

Question 14

Refer to the exhibit. An SAP administrator runs the AWS CLI command and receives the output shown. The SAP application server (instance i-0abcd1234) is in 'running' state, but the SAP application is not reachable. The security group allows inbound traffic on port 3200. What is the MOST likely cause of the issue?

Accepted Answer

The operating system firewall on the instance is blocking port 3200.. The instance is in 'running' state and the security group allows inbound traffic on port 3200, yet the SAP application is unreachable. This indicates a host-level firewall (e.g., iptables, firewalld, or Windows Firewall) on the SAP application server is blocking inbound connections to port 3200, which operates independently of AWS security groups and network ACLs.

Answer

The network ACL for the subnet is blocking outbound traffic.

Answer

The instance is in a stopped state.

Answer

The security group inbound rule for port 3200 is not applied to the instance.

Question 15

A company is migrating an SAP environment to AWS and wants to automate the provisioning of infrastructure using code. Which AWS service should be used for this purpose?

Accepted Answer

AWS CloudFormation. AWS CloudFormation enables infrastructure as code (IaC) to provision and manage AWS resources in a repeatable and automated manner, which is ideal for automating SAP environment provisioning. Option A (AWS Elastic Beanstalk) is incorrect because it is a platform-as-a-service (PaaS) for deploying and scaling web applications, not for provisioning general infrastructure. Option B (AWS CloudFormation) is correct because it directly provides infrastructure as code. Option C (AWS CodeDeploy) is incorrect because it automates application deployments to compute services, not infrastructure provisioning. Option D (AWS OpsWorks) is incorrect because it is a configuration management service using Chef/Puppet, not a direct infrastructure provisioning service like CloudFormation.

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Answer

AWS OpsWorks
