PAS-C01 Practice Test 30 — 15 Questions

Question 1

A company is designing a disaster recovery (DR) strategy for its SAP HANA database on AWS. The primary site is in us-east-1. The DR site must be in us-west-2. The company requires a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. Which AWS service should be used for replicating HANA data?

Accepted Answer

SAP HANA System Replication to an EC2 instance in us-west-2.. Option B is correct because SAP HANA System Replication with HANA replication over AWS Direct Connect or VPN to a different region can achieve an RPO of seconds and RTO of minutes, meeting the requirements. Option A is incorrect because Amazon EBS Snapshots are not real-time and cannot achieve 15-minute RPO. Option C is incorrect because S3 Cross-Region Replication is for S3 objects, not for HANA database files. Option D is incorrect because AWS Database Migration Service is for one-time migrations, not continuous replication.

Answer

AWS Database Migration Service with ongoing replication.

Answer

Amazon EBS Snapshots copied to us-west-2 every hour.

Answer

Amazon S3 Cross-Region Replication for HANA data files.

Question 2

A company is preparing to migrate its SAP ECC 6.0 system to SAP S/4HANA on AWS. The current on-premises system includes a single application server and a database server running Oracle. The total database size is 1.5 TB. The company plans to use a homogeneous migration approach by exporting the existing Oracle database and importing it into a new SAP HANA database running on AWS. The migration must be completed within a tight weekend window. The company has established a 1 Gbps AWS Direct Connect connection to AWS. Which migration strategy should the company use to minimize downtime?

Accepted Answer

Use the SAP Software Update Manager (SUM) with Database Migration Option (DMO). Perform the migration in a weekend window using the delta replication feature.. Option B is correct because SAP HANA Database Migration Option (DMO) with System Move is the recommended tool for migrating from any source database to SAP HANA. It can perform the migration online with minimal downtime by using a delta replication phase. The DMO tool is included in SAP Software Update Manager (SUM). Option A is incorrect because exporting and importing using SAP HANA Studio is a manual process that would take longer and require more downtime. Option C is incorrect because AWS Database Migration Service (DMS) does not support Oracle to HANA migrations with schema conversion. Option D is incorrect because using an Application Load Balancer is not a migration strategy.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate the Oracle database to HANA, and then switch over.

Answer

Use an Application Load Balancer to redirect traffic to the new HANA system after exporting the data to S3.

Answer

Use the SAP HANA Studio migration wizard to export the Oracle database and import it into HANA. This is the simplest method.

Question 3

A company is running SAP HANA on AWS. The HANA database is deployed on an r5.8xlarge instance. The company notices high CPU utilization on the instance during peak loads. The SAP team confirms that the HANA workload requires more CPU capacity. What is the most cost-effective way to increase CPU capacity without changing the instance family?

Accepted Answer

Resize the instance to a larger instance type in the r5 family.. Option D is correct because r5.8xlarge is a fixed instance size. To increase CPU capacity, the company can move to a larger instance in the same family (r5.12xlarge or r5.24xlarge) using instance resizing (stop the instance, change instance type, start). Option A is incorrect because adding EBS volumes does not increase CPU. Option B is incorrect because launching additional instances would require a distributed HANA setup which may not be cost-effective. Option C is incorrect because auto scaling is not applicable for a single HANA instance.

Answer

Add more EBS volumes with higher IOPS to offload CPU.

Answer

Launch additional r5.8xlarge instances and configure HANA scale-out.

Answer

Configure Auto Scaling to add instances during peak load.

Question 4

A company runs SAP on AWS and wants to back up its SAP HANA database to Amazon S3. The database is 2 TB in size. The backup must be encrypted at rest in S3 and must be cost-effective. Which approach should the company use?

Accepted Answer

Install the SAP HANA Backint agent for Amazon S3 and configure it to use SSE-S3 encryption. Option C is correct because Backint agent for SAP HANA integrates with AWS Backup and uses S3, enabling server-side encryption with SSE-S3 at no extra cost. Option A is wrong because AWS Backup does not support direct backup of SAP HANA to S3 without Backint. Option B is wrong because the SAP HANA file-level backup would require backup to EBS and then to S3, adding complexity. Option D is wrong because manual copy to S3 is not automated.

Answer

Use AWS Backup to directly back up the SAP HANA database to S3 with SSE-S3

Answer

Configure a cron job to copy the SAP HANA backup files from EBS to S3 using AWS CLI

Answer

Use SAP HANA Studio to export the database to a file on EBS and then manually upload to S3

Question 5

An SAP administrator is migrating an SAP Business Suite system from on-premises to AWS. The system uses an Oracle database that is 2 TB in size. The bandwidth between the on-premises data center and AWS is limited to 100 Mbps. The migration must be completed within a weekend (48 hours). The administrator decides to use AWS DMS for ongoing replication after an initial full load. However, the initial full load takes too long. What should the administrator do to accelerate the initial full load?

Accepted Answer

Use AWS Snowball Edge to physically transfer the database backup to AWS, then restore and use DMS for ongoing replication.. Option A is correct because using AWS Snowball Edge to transfer the database backup to AWS bypasses the network bottleneck. Option B is wrong because increasing instance size does not improve network speed. Option C is wrong because disabling encryption does not significantly speed up transfer. Option D is wrong because S3 Transfer Acceleration improves speed but may still be limited by 100 Mbps.

Answer

Disable encryption on the database backup to reduce transfer overhead.

Answer

Increase the size of the DMS replication instance to the largest available.

Answer

Use Amazon S3 Transfer Acceleration to speed up the upload.

Question 6

Which THREE of the following are best practices for securing SAP systems on AWS?

Accepted Answer

Encrypt EBS volumes using AWS KMS.. Options A, B, and D are correct. A: Using AWS KMS to encrypt EBS volumes ensures data at rest is encrypted. B: Security groups are stateful firewalls that control traffic between instances. D: IAM roles provide temporary credentials for EC2 instances to access AWS services securely. Option C is incorrect because public subnets expose instances to the internet, which is not a security best practice. Option E is incorrect because root user credentials should not be used for daily operations; IAM users are preferred.

Answer

Place all SAP instances in public subnets for easier access.

Answer

Store AWS credentials in the SAP application code for API access.

Question 7

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. Options A and B are correct. A: HANA System Replication is the primary method for synchronous replication across AZs. B: A Pacemaker cluster manages automatic failover. Option C is wrong because manual failover is not HA. Option D is wrong because EBS snapshots are not real-time. Option E is wrong because S3 replication is not for database.

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 8

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.. For SAP HANA high availability, the ASCS and ERS instances must run on separate EC2 instances (or separate Availability Zones) to avoid a single point of failure. Using a Network Load Balancer with a floating IP addresses for the virtual hostname ensures seamless failover. Option B (single instance) would not provide HA. Option E (using a Classic Load Balancer) is not recommended for SAP ASCS/ERS; AWS recommends NLB. Option C (single AZ) defeats HA. Option D (application-based routing) is not needed; NLB uses IP/host-based routing.

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 9

A company is running a large SAP S/4HANA production system on AWS. The system consists of a single HANA database instance running on an r5.24xlarge EC2 instance (with 768 GB of RAM), and multiple application server instances behind an Application Load Balancer. The database uses six EBS io1 volumes for data and log files, each with 20,000 provisioned IOPS. The application servers are in an Auto Scaling group. Recently, the company experienced a prolonged database outage when the primary EC2 instance failed. The recovery took over 4 hours because a new instance had to be launched and snapshots restored. The company wants to improve the Recovery Time Objective (RTO) to less than 30 minutes for the HANA database. They also want to minimize data loss with an RPO of less than 5 minutes. The company has a second AWS region (us-west-2) available for disaster recovery but prefers to keep costs low for the DR site. Which solution should the company implement?

Accepted Answer

Set up SAP HANA System Replication to a standby HANA instance in a different Availability Zone. Use a smaller instance type for the standby to reduce costs. Automate failover using a cluster manager like Pacemaker.. Option C is correct because SAP HANA System Replication (HSR) provides near-synchronous replication with a typical RPO of seconds and can be configured with automatic takeover to a standby instance in another Availability Zone. The standby can be a smaller instance (e.g., r5.12xlarge) to reduce costs. The takeover can be automated with Pacemaker, achieving RTO of minutes. Option A is incorrect because a new EC2 instance launch and snapshot restore cannot achieve 30-minute RTO. Option B is incorrect because Multi-AZ RDS is not for HANA. Option D is incorrect because HSR to a smaller instance in the same region provides DR but does not use the second region as specified.

Answer

Configure SAP HANA System Replication to a standby instance in the same region but use a larger instance to ensure capacity.

Answer

Configure automated Amazon EBS snapshots every 5 minutes and create an AMI for the HANA instance. In the event of a failure, launch a new instance from the AMI in the same Availability Zone.

Answer

Use Amazon RDS for SAP HANA with Multi-AZ deployment to automatically failover to a standby in another Availability Zone.

Question 10

An SAP system on AWS uses a shared file system for /sapmnt and /usr/sap/trans mounted from an EC2 instance running NFS. The NFS server experiences a failure causing downtime for all SAP application servers. The company wants a highly available shared file system with automatic failover. The budget is limited, and the company prefers a fully managed solution. Which AWS service should the company use?

Accepted Answer

Amazon EFS. Option A is correct because Amazon EFS is a fully managed NFS file system that is highly available across multiple Availability Zones. Option B is wrong because FSx for Windows File Server is not POSIX-compliant for SAP. Option C is wrong because EBS is not shared. Option D is wrong because S3 is not a POSIX file system.

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with a cluster file system

Answer

Amazon S3 with s3fs-fuse

Question 11

A company is designing a disaster recovery (DR) strategy for its SAP environment on AWS. The primary site is in us-east-1 and the DR site in us-west-2. The SAP HANA database is 3 TB and uses HANA System Replication (HSR) in async mode. The RPO requirement is 15 minutes. What is the most cost-effective way to meet the RPO?

Accepted Answer

Configure HANA System Replication in asynchronous mode over AWS Direct Connect.. HSR in async mode over AWS Direct Connect provides low latency and meets the RPO of 15 minutes. Option A (sync mode) would be costly and may have performance impact. Option B (S3 backup) has longer RPO. Option C (EBS snapshots) also has longer RPO. Option D is correct.

Answer

Take full database backups to Amazon S3 every 15 minutes.

Answer

Use EBS snapshots every 5 minutes to replicate data to DR region.

Answer

Use HANA System Replication in synchronous mode to ensure zero data loss.

Question 12

A company is migrating its SAP ERP system to AWS and wants to minimize downtime during the migration. Which THREE strategies should be considered? (Choose three.)

Accepted Answer

Use Amazon S3 Transfer Acceleration to speed up data transfer.. Using SAP Landscape Transformation (SLT) for real-time data replication, setting up AWS DMS for ongoing replication, and performing a near-zero downtime migration using SAP SWPM with DB migration option are all valid strategies. Option B (shutting down source) causes downtime. Option D (full export/import) causes extended downtime. Option E (using only S3) is not a migration strategy for live systems.

Answer

Shut down the source system and perform a full database export to S3.

Answer

Perform a full export and import of the SAP system during a maintenance window.

Question 13

A company is running SAP HANA on AWS using a scale-out architecture with multiple worker nodes. The system is used for real-time analytics. Recently, query performance has degraded. The HANA administrator notices that the data is not evenly distributed across nodes. What is the best course of action?

Accepted Answer

Redistribute the tables across nodes using HANA's table partitioning features.. HANA scale-out relies on table partitioning and distribution to ensure even data distribution. Redistributing tables using ALTER TABLE with REORGANIZE or reloading data can fix imbalance. Option A (add nodes) may help but does not fix existing imbalance. Option B (change instance type) is not directly related. Option D (memory) is not the issue. Option C is the targeted fix.

Answer

Increase the memory allocation for the HANA database.

Answer

Add more worker nodes to the scale-out cluster to distribute the load.

Answer

Upgrade the EC2 instance type of all nodes to a memory-optimized type.

Question 14

A company runs SAP S/4HANA on AWS in a multi-AZ deployment. The SAP HANA database is 2 TB and uses EBS gp3 volumes. During a monthly patching cycle, the primary database fails over to the secondary, but the secondary takes over 30 minutes to come online. Which TWO changes would most likely reduce the failover time? (Choose two.)

Accepted Answer

Increase the provisioned IOPS and throughput on the EBS log volumes.. HANA system replication in a multi-AZ setup can be optimized by using AWS placement groups for low latency, and increasing the log volume size to handle higher I/O during replication. Option A (single AZ) defeats HA. Option B (increasing log volume) helps sustain replication throughput. Option C (using different instance types) is not recommended. Option D (placement group) reduces network latency. Option E (EBS optimization) is already enabled by default on modern instances.

Answer

Use different EC2 instance types for primary and secondary to balance cost.

Answer

Deploy all HANA nodes in the same Availability Zone to reduce network latency.

Answer

Enable EBS optimization on the secondary instance's EBS volumes.

Question 15

A company is planning to migrate its SAP ECC system to SAP S/4HANA on AWS. The current system uses an IBM Db2 database on-premises. The target system will use SAP HANA as the database. The company wants to perform the migration with minimal downtime. Which tool or method should be used?

Accepted Answer

Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO).. SAP provides the Software Update Manager (SUM) with Database Migration Option (DMO) that supports migration from Db2 to HANA. Option A (IBM tools) are not applicable. Option B (AWS DMS) does not support Db2 to HANA well. Option C (SAP LT) is for ongoing replication, not one-time migration. Option D is correct.

Answer

Use IBM Db2 native tools to export the database and import into HANA.

Answer

Use AWS Database Migration Service (DMS) to replicate data from Db2 to HANA.

Answer

Use SAP Landscape Transformation (SLT) to replicate data in real-time.
