PAS-C01 Practice Test 10 — 10 Questions

Question 1

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?

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

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 2

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 3

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 4

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 5

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

Question 6

A company runs SAP Business Warehouse (BW) on AWS. The BW system uses a single HANA database instance on an r5.12xlarge EC2 instance with 4 EBS io1 volumes for data. The company has noticed that during peak data loads, the CPU utilization on the HANA instance reaches 90%. An SAP consultant recommends increasing the CPU capacity. The company wants to minimize costs and avoid over-provisioning. What is the most cost-effective solution to increase CPU capacity for the HANA instance?

Accepted Answer

Change the EC2 instance type to a larger size in the r5 family, such as r5.16xlarge, to add more vCPUs.. The simplest and most cost-effective way to increase CPU capacity is to resize the EC2 instance to a larger instance type within the same family (e.g., r5.16xlarge or r5.24xlarge). This provides more vCPUs without needing to change the architecture. Option B is incorrect because increasing EBS volume IOPS does not add CPU capacity. Option C is incorrect because launching additional HANA instances for scale-out is complex and more expensive. Option D is incorrect because using a different instance family (e.g., compute-optimized) may require reconfiguration and is not as straightforward as resizing within the same family.

Answer

Increase the provisioned IOPS on the EBS volumes to improve I/O performance.

Answer

Deploy additional HANA worker nodes and configure a scale-out system.

Answer

Migrate the HANA instance to a compute-optimized instance family, such as c5.

Question 7

A company is migrating a SAP BusinessObjects environment to AWS. Which AWS service can be used to automate the deployment of the SAP BusinessObjects components?

Accepted Answer

AWS CloudFormation. AWS CloudFormation allows infrastructure as code to automate the deployment of SAP BusinessObjects. Option A is wrong because AWS OpsWorks is for Chef/Puppet, not directly for SAP. Option B is wrong because AWS Elastic Beanstalk is for web applications, not SAP. Option C is wrong because AWS CodePipeline is for CI/CD, not infrastructure deployment.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodePipeline

Question 8

A company is migrating an SAP HANA database from on-premises to AWS. The current system uses 8 TB of data. The migration must be completed within a 4-hour downtime window. The network link has 1 Gbps throughput. What is the MOST efficient migration strategy?

Accepted Answer

Use AWS Snowball Edge to transfer the data offline. At 1 Gbps, transferring 8 TB over the network would take approximately 18 hours (8 TB * 1024 GB/TB * 8 bits/byte / 1 Gbps = 65536 seconds = ~18 hours), exceeding the 4-hour window. AWS Snowball Edge (Option D) can transport 8 TB offline, avoiding the bandwidth constraint. Option A (AWS DMS) would not meet the time constraint. Option B (Direct Connect) still has the same bandwidth limitation. Option C (AWS MGN) is for server migration, not database migration.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication

Answer

Use AWS Direct Connect to increase bandwidth

Answer

Use AWS Application Migration Service (MGN)

Question 9

A company is migrating an SAP BusinessObjects (BO) system to AWS. The system includes a large number of reports and users. What is the recommended approach to migrate the SAP BO repository?

Accepted Answer

Use the SAP BusinessObjects Promotion Management tool to export and import the repository. SAP BusinessObjects provides a built-in Promotion Management tool for exporting and importing the repository, ensuring a clean migration of reports, users, and other content. Option A is incorrect because reinstalling and manually copying report files is error-prone and misses the repository structure. Option B is incorrect because AWS DMS is designed for database migration, not for SAP BO application-level content. Option D is incorrect because manual extraction is not recommended and lacks integrity checks.

Answer

Reinstall SAP BO on AWS and manually copy the report files

Answer

Use AWS Database Migration Service (DMS) to replicate the repository database

Answer

Manually extract the repository files from the database and copy them to AWS

Question 10

A company is running SAP Business Suite on AWS and wants to improve the disaster recovery posture by replicating data to another AWS Region. The solution must have a recovery time objective (RTO) of less than 15 minutes and a recovery point objective (RPO) of less than 5 minutes. Which approach should they take?

Accepted Answer

Configure SAP HANA system replication with synchronous mode.. SAP HANA system replication in synchronous mode ensures that every committed transaction is replicated to the secondary region before acknowledging the commit, achieving an RPO of effectively zero (less than 5 minutes) and enabling rapid failover within seconds, meeting the RTO of under 15 minutes. This is the only native SAP solution that provides the required low-latency, consistent replication for SAP Business Suite on AWS.

Answer

Use AWS Database Migration Service for continuous replication.

Answer

Use Amazon S3 cross-Region replication for transaction logs.

Answer

Use AWS Backup to create cross-Region EBS snapshots every 5 minutes.
