PAS-C01 Practice Test 11 — 15 Questions

Question 1

A company is running SAP on AWS and needs to ensure high availability for their SAP HANA database. They have set up a multi-AZ deployment with replication. During a planned failover test, the secondary node fails to take over. Which AWS service should be used to monitor and automatically remediate the replication status?

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

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch is the correct service to monitor SAP HANA replication status. It can track metrics such as replication lag or state and, through CloudWatch Alarms, automatically trigger remediation actions like invoking an AWS Lambda function or an AWS Systems Manager Automation runbook to restart replication or adjust configurations. AWS Direct Connect is a network connectivity service and does not monitor or remediate database replication. AWS Elastic Beanstalk is a PaaS service for web applications, not HANA replication. AWS Lambda can perform remediation but does not natively monitor; it requires CloudWatch for triggering.

Answer

AWS Elastic Beanstalk

Answer

AWS Direct Connect

Answer

AWS Lambda

Question 2

An SAP HANA system on AWS is experiencing slow backup performance when using Backint to Amazon S3. The backup throughput is only 200 MB/s. The environment uses an m5.24xlarge instance with 25 Gbps network. What is the most likely cause and solution?

Accepted Answer

The Backint agent is configured with too few parallel streams. Increase the number of streams in the Backint configuration.. The most likely cause is that the Backint agent is configured with too few parallel streams. Backint for SAP HANA on AWS uses multiple concurrent streams to upload backup data to S3; if the stream count is too low, it cannot saturate the available network bandwidth, resulting in throughput far below the instance's 25 Gbps capacity. Increasing the number of parallel streams in the Backint configuration allows the backup to fully utilize the network and achieve higher throughput.

Answer

The network bandwidth is insufficient. Enable S3 Transfer Acceleration.

Answer

The EBS volumes are too slow. Use instance store volumes for temporary storage.

Answer

The S3 bucket is not using multipart upload. Enable multipart upload on the bucket.

Question 3

A company is running SAP HANA on AWS and needs to ensure high availability for the SAP Central Services (ASCS/ERS) instance. Which TWO actions should be taken to achieve this? (Choose two.)

Accepted Answer

Configure ASCS and ERS on separate EC2 instances in different Availability Zones.. SAP Central Services (ASCS/ERS) must run on separate EC2 instances to avoid a single point of failure. Placing them in different Availability Zones (AZs) ensures that if one AZ fails, the other instance can take over, providing high availability. This aligns with SAP's recommendation for a multi-AZ architecture for ASCS/ERS in an SAP HANA on AWS environment.

Answer

Use an Application Load Balancer to distribute traffic between ASCS and ERS instances.

Answer

Deploy both ASCS and ERS on the same EC2 instance to reduce latency.

Answer

Place both ASCS and ERS in the same Availability Zone to minimize network latency.

Question 4

An SAP HANA database on AWS requires a backup strategy that includes incremental backups to minimize storage costs. The database is large (2 TB) and the backup window is short. Which AWS service or feature is most suitable for performing incremental backups of SAP HANA?

Accepted Answer

Amazon EBS Snapshots. D is correct because Amazon EBS Snapshots provide native incremental backup capability at the block level, which is ideal for large SAP HANA databases (2 TB) with short backup windows. Snapshots capture only changed blocks since the last snapshot, minimizing storage costs and backup time, and can be automated via AWS Backup or custom scripts.

Answer

Amazon S3 Lifecycle policies

Answer

AWS Backup

Answer

SAP HANA backup to Amazon S3

Question 5

A customer wants to migrate their SAP HANA database to AWS and needs to ensure that the EBS volumes for /hana/data and /hana/log are configured for maximum throughput and low latency. Which EBS volume type should be used for /hana/data?

Accepted Answer

io2. For SAP HANA workloads on AWS, the /hana/data volume requires the highest level of IOPS and low latency to support real-time data processing. io2 Block Express volumes provide up to 256,000 IOPS and sub-millisecond latency, making them the correct choice for /hana/data. io2 volumes also offer 99.999% durability, which is critical for SAP HANA database consistency.

Question 6

A company is migrating its SAP ERP system (with Oracle database) to AWS using the SAP-certified approach. The current on-premises environment uses Oracle RAC for high availability. The company wants to reduce licensing costs and simplify the architecture on AWS. Which of the following is the MOST efficient migration strategy?

Accepted Answer

Use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.. AWS does not support Oracle RAC in a fully supported manner for SAP. The best practice is to migrate to Amazon RDS for Oracle (single instance) or use a single Oracle instance on EC2. Using AWS DMS with ongoing replication minimizes downtime. Option C is correct because it uses DMS to migrate the Oracle database to Amazon RDS for Oracle single instance, which reduces licensing costs, and AWS MGN for the application servers, simplifying the architecture. Option A is incorrect because RDS for Oracle does not support Oracle RAC. Option B uses AWS DataSync, which is for file transfer, not database replication. Option D keeps Oracle RAC, which is costly and not simplified.

Answer

Use AWS DMS to migrate the database to Amazon RDS for Oracle, but then configure RDS for Oracle RAC.

Answer

Use AWS DataSync to copy the Oracle database files to EBS volumes, then restore on an EC2 instance.

Answer

Lift-and-shift the Oracle RAC cluster to EC2 using AWS Application Migration Service.

Question 7

A company is migrating a legacy mainframe application to AWS. The application uses COBOL and VSAM files. Which AWS service can best replicate the VSAM file system?

Accepted Answer

Amazon FSx for NetApp ONTAP. Amazon FSx for NetApp ONTAP provides a fully managed NetApp ONTAP file system that supports NFS, SMB, and iSCSI protocols. VSAM files from mainframe can be migrated to an NFS share on FSx for ONTAP, preserving file access patterns. Option A is incorrect because Amazon S3 is object storage and does not provide a file system interface required for VSAM. Option C is incorrect because Amazon EBS is block-level storage that attaches to EC2 instances and does not offer a native file system for VSAM. Option D is incorrect because Amazon EFS is a POSIX-compliant file system but does not support the specific VSAM file structures and features needed.

Answer

Amazon S3 with Object Lock

Answer

Amazon Elastic Block Store (EBS)

Answer

Amazon Elastic File System (EFS)

Question 8

An SAP Basis administrator is deploying a new SAP S/4HANA system on AWS. The architecture uses a multi-AZ deployment for high availability: primary database in us-east-1a, standby in us-east-1b. The ASCS instance is in us-east-1a with a replicated enqueue server (ERS) in us-east-1b. For the application servers, two instances are in us-east-1a and two in us-east-1b. The administrator needs to ensure that the SAP system remains available if an entire Availability Zone fails. What is the MOST important configuration step to achieve this?

Accepted Answer

Enable HANA system replication and configure ASCS with enqueue replication across the two AZs.. High availability across AZs requires both HANA system replication and enqueue replication. HANA system replication ensures the database can fail over to the standby in the other AZ. Enqueue replication (ERS) ensures that the lock table is replicated so that the ASCS can fail over without losing locks. Option A is wrong because Route53 routing only handles DNS resolution, not automatic failover of SAP services. Option B is wrong because an Application Load Balancer does not provide database failover; it distributes traffic to application servers. Option D is wrong because larger instance sizes increase capacity but do not provide high availability in case of AZ failure.

Answer

Configure Amazon Route53 with a failover routing policy for the SAP application URLs.

Answer

Place an Application Load Balancer in front of the database instances.

Answer

Use larger instance types for all SAP instances to handle the load.

Question 9

An SAP administrator runs the command shown in the exhibit. The volume is attached to an EC2 instance. The administrator plans to increase the volume size to 1000 GiB. After resizing, the volume type remains gp2. What is the expected baseline IOPS for the resized volume?

Accepted Answer

3000 IOPS. Gp2 volumes have a baseline IOPS of 3 IOPS per GiB, up to a maximum of 16,000 IOPS. For a 1000 GiB gp2 volume, the calculation is 1000 × 3 = 3000 IOPS, which is below the 16,000 IOPS cap, so the expected baseline IOPS is exactly 3000.

Answer

4500 IOPS

Answer

16,000 IOPS

Answer

1500 IOPS

Question 10

A company has an SAP HANA database running on an EC2 instance with EBS volumes. The database requires 10,000 IOPS consistently. The current volume type is gp3 with 3000 IOPS. Which change should be made to meet the IOPS requirement?

Accepted Answer

Change the volume type to io2 Block Express and provision 10,000 IOPS.. Io2 Block Express volumes are designed for high-performance workloads and can provision up to 256,000 IOPS, easily meeting the 10,000 IOPS requirement. Option B is wrong because increasing the volume size of a gp3 volume does not automatically increase IOPS beyond the baseline; gp3 IOPS are provisioned independently of size. Option C is wrong because while gp3 can be provisioned up to 16,000 IOPS, io2 Block Express offers consistent low-latency performance needed for SAP HANA. Option D is wrong because instance store volumes are ephemeral and data is lost on instance stop or termination, making them unsuitable for persistent database storage.

Answer

Increase the volume size of the gp3 volume to automatically increase IOPS.

Answer

Increase the IOPS on the existing gp3 volume to 10,000.

Answer

Add an instance store volume and move the data to it.

Question 11

A company is running SAP BusinessObjects on AWS. The application server is on an EC2 instance, and the database is on Amazon RDS for SQL Server. Users report that reports are taking longer to generate than expected. Which AWS service can be used to analyze the performance bottleneck?

Accepted Answer

Amazon CloudWatch with enhanced monitoring for RDS. Amazon CloudWatch with enhanced monitoring provides detailed OS-level metrics for RDS (CPU, memory, disk I/O, and network), along with EC2 metrics, enabling analysis of performance bottlenecks in SAP BusinessObjects. Option A (AWS Trusted Advisor) offers best-practice recommendations, not performance analysis. Option B (AWS CloudTrail) audits API calls, which is unrelated to performance. Option C (AWS X-Ray) is designed for tracing requests in distributed applications, not for database-level performance monitoring.

Answer

AWS Trusted Advisor

Answer

AWS CloudTrail

Answer

AWS X-Ray

Question 12

An SAP system running on AWS is experiencing performance degradation. The system uses a shared file system for /sapmnt and /usr/sap/trans. The file system is hosted on an Amazon EFS file system. Which configuration change is most likely to improve throughput for these file systems?

Accepted Answer

Change the EFS performance mode to Max I/O to support higher levels of aggregate throughput and operations per second.. Amazon EFS Max I/O performance mode is designed for workloads with high throughput and parallel operations, such as SAP shared file systems for /sapmnt and /usr/sap/trans. Option B (Provisioned Throughput) provides consistent throughput but is not specifically optimized for parallel access and may incur additional cost. Option C (General Purpose Burstable) is the default mode, which is suitable for lower throughput workloads and would not improve performance. Option D (Enable burst credits) is not a configurable option; EFS automatically uses burst credits when in Burstable mode, so enabling them is not applicable.

Answer

Increase the Provisioned Throughput of the EFS file system.

Answer

Switch the EFS file system to General Purpose (Burstable) performance mode.

Answer

Enable burst credits on the EFS file system to handle peak loads.

Question 13

A company is migrating its SAP ERP system to AWS and needs to minimize network latency between the SAP application servers and the database. Which architecture is recommended?

Accepted Answer

Place both the application and database servers in the same Availability Zone. Placing both the SAP application servers and the database in the same Availability Zone (AZ) minimizes network latency by keeping traffic within a single data center. Option A is incorrect because different AZs introduce additional latency due to inter-AZ data transfer. Option C is incorrect because different regions add significant latency and incur higher costs. Option D is incorrect because keeping the database on-premises introduces network latency over the internet or VPN connection.

Answer

Place the application servers in one AZ and the database in a different AZ

Answer

Place the application servers in one region and the database in another region

Answer

Keep the database on-premises and move only the application servers to AWS

Question 14

A company is migrating an SAP environment to AWS and needs to ensure that the SAP HANA database can be backed up efficiently. Which THREE AWS services can be used together to implement a backup strategy for SAP HANA?

Accepted Answer

Amazon EBS snapshots. The correct answers are B, D, and E. Amazon EBS snapshots provide point-in-time backups of SAP HANA data volumes. AWS Backup can automate and manage backup schedules for EBS snapshots and other resources. Amazon S3 can be used for long-term storage of backup files. Option A (Amazon RDS) is incorrect because SAP HANA is not an RDS database; it runs on EC2 with EBS volumes. Option C (Amazon DynamoDB) is a NoSQL database not used for SAP HANA backups.

Answer

Amazon RDS

Answer

Amazon DynamoDB

Question 15

A company is planning to migrate an SAP ERP system to AWS. They want to use an existing software license with no additional cost. Which AWS service allows them to bring their own SAP license?

Accepted Answer

AWS License Manager. AWS License Manager is the correct service for bring-your-own-license (BYOL) for SAP. Option A is wrong because AWS Organizations is for multi-account governance. Option C is wrong because AWS Systems Manager is for management, not licensing. Option D is wrong because AWS Service Catalog is for provisioning approved services.

Answer

AWS Organizations

Answer

AWS Systems Manager

Answer

AWS Service Catalog
