PAS-C01 Practice Exam 53 — 20 Questions

Question 1

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as its database. The company has a complex networking setup with multiple VPCs and on-premises connectivity via AWS Direct Connect. The SAP HANA system replication will be used for high availability across two Availability Zones. What is the minimum number of Elastic Network Interfaces (ENIs) required per HANA instance to support the recommended network architecture?

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

Accepted Answer

2. The minimum number of ENIs recommended for SAP HANA system replication across Availability Zones is 2. This allows separation of client traffic from HANA system replication traffic, which is a best practice. A single ENI can technically carry all traffic but does not adhere to the recommended network architecture. Option A (2) is the minimum, while Option B (1) is insufficient.

Answer

1

Question 2

An SAP HANA administrator sees the error log entry shown in the exhibit. The error occurs when a scheduled job tries to insert data into the BKPF table. What is the MOST likely cause?

Accepted Answer

The credentials used by the scheduled job are incorrect.. The error log entry indicates that the scheduled job is failing during an INSERT operation on the BKPF table. In SAP HANA, when a scheduled job fails with an authentication or authorization error, the most common cause is incorrect credentials being used by the job's connection to the database. This is because the job's runtime context does not have the correct user or password to establish a valid session, leading to a failure before any SQL operation is attempted.

Answer

The user does not have INSERT privilege on the BKPF table.

Answer

The SQL statement has a syntax error.

Answer

The table BKPF is full and cannot accept new rows.

Question 3

An SAP HANA database on EC2 is experiencing high I/O latency. The database uses a single EBS volume for /hana/log. The volume is a gp2 volume with 1000 GB size. The administrator notices that the volume's burst balance is depleted. Which action should be taken to improve latency?

Accepted Answer

Change the volume type to Provisioned IOPS SSD (io1) with sufficient IOPS. Switching to io1 provides consistent IOPS without burst balance. Option C (increasing size to 2000 GB) would double the baseline IOPS but not eliminate burst dependency. Option B (adding more volumes) may help but is more complex. Option A (using st1) is for throughput, not low latency.

Answer

Change the volume type to Throughput Optimized HDD (st1)

Answer

Add additional gp2 volumes and stripe them in a RAID 0

Answer

Increase the volume size to 2000 GB to double the baseline IOPS

Question 4

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

Question 5

A company is migrating an SAP HANA database using SAP HANA System Replication (HSR) to AWS. The target EC2 instance is in a different AWS Region than the source. The network latency between regions is high. What should the migration team configure to ensure successful replication?

Accepted Answer

Use AWS Global Accelerator to route traffic over the AWS global network. A VPN connection adds overhead and latency over the internet, worsening replication issues. Option B is incorrect because disabling HSR preload reduces memory usage but does not address high latency; it may even increase recovery time. Option C is correct because AWS Global Accelerator uses the AWS global network to optimize routing, reducing latency impact for HSR replication. Option D is incorrect because increasing HSR timeout values only masks timeout symptoms without resolving the underlying latency problem.

Answer

Set up a VPN connection to the target region

Answer

Disable HSR preload on the target

Answer

Increase the HSR timeout values significantly

Question 6

A company is designing a disaster recovery (DR) strategy for its SAP system on AWS. The primary site is in us-east-1 and the DR site in us-west-2. The RTO is 4 hours and RPO is 1 hour. Which AWS service should be used for cross-region replication of the SAP HANA database backups stored in Amazon S3?

Accepted Answer

Amazon S3 Cross-Region Replication (CRR).. Amazon S3 Cross-Region Replication (CRR) is the correct choice because it automatically replicates objects (including SAP HANA database backups) from a source S3 bucket in us-east-1 to a destination bucket in us-west-2, meeting the 1-hour RPO by ensuring backups are available in the DR region within minutes of upload. CRR operates asynchronously at the object level, requires no additional infrastructure, and directly supports the stated requirement for cross-region replication of S3-stored backups without introducing extra latency or complexity.

Answer

AWS Backup with a cross-region backup plan.

Answer

Use AWS Storage Gateway to replicate backups.

Answer

Enable S3 Versioning on the source bucket.

Question 7

A company is planning to migrate its SAP HANA database to AWS. The database is 5 TB in size and requires high IOPS for online transaction processing (OLTP) workloads. Which THREE AWS storage options are suitable for SAP HANA data volumes? (Choose THREE.)

Accepted Answer

EC2 instance store (NVMe SSD). EC2 instance store (NVMe SSD) provides very high IOPS and low latency directly attached to the host, which is suitable for SAP HANA data volumes that require high performance for OLTP workloads. However, instance store is ephemeral, so it must be used with replication or backup strategies for persistence.

Answer

Amazon S3

Answer

Amazon EFS

Question 8

An SAP administrator needs to ensure that all API calls made to AWS services by the SAP system are logged for auditing purposes. Which AWS service should be enabled?

Accepted Answer

AWS CloudTrail. AWS CloudTrail is the correct service because it records all API calls made to AWS services, including the caller identity, time, source IP, and request parameters. For SAP systems requiring audit logs of AWS interactions, CloudTrail provides the necessary event history for security analysis, resource change tracking, and compliance auditing.

Answer

AWS Config

Answer

Amazon CloudWatch

Answer

VPC Flow Logs

Question 9

A company is migrating an SAP ERP system to AWS. The SAP application servers use a shared /sapmnt filesystem. Which AWS storage solution is most suitable for this shared filesystem with high availability?

Accepted Answer

Amazon EFS. (Amazon EFS) is correct because Amazon EFS is a managed NFS filesystem that provides high availability and can be shared across multiple EC2 instances, making it suitable for the shared /sapmnt filesystem required by SAP. Option A (Amazon S3) is wrong because S3 is object storage, not a POSIX-compliant filesystem, and cannot be mounted as a shared filesystem. Option B (Amazon FSx for Windows File Server) is incorrect because SAP typically runs on Linux, and FSx for Windows is designed for Windows workloads. Option C (Amazon EBS with Multi-Attach) is not ideal because EBS Multi-Attach has limitations (max 16 instances, single Availability Zone) and is not as scalable or resilient as EFS for this use case.

Answer

Amazon S3 with a mount point

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with Multi-Attach enabled

Question 10

A company is designing a disaster recovery solution for SAP HANA on AWS using HANA System Replication. The primary site is in us-east-1 and the DR site is in us-west-2. Which component is required to enable replication across Regions?

Accepted Answer

AWS Site-to-Site VPN or AWS Direct Connect between the two Regions. To enable HANA System Replication (HSR) across AWS Regions, a reliable, low-latency network connection is required. AWS Site-to-Site VPN or AWS Direct Connect provides a dedicated, secure network path that meets SAP's latency and stability requirements. The other options (VPC peering, automated EBS snapshots, Global Accelerator, S3 Transfer Acceleration) are not required for HSR; HSR performs its own initial data synchronization, and VPC peering does not guarantee the required performance for HANA replication.

Answer

VPC peering between the two VPCs

Answer

Automated EBS snapshots of /hana/data and /hana/log volumes in us-east-1, copied to us-west-2

Answer

AWS Global Accelerator

Answer

Amazon S3 Transfer Acceleration

Question 11

An SAP administrator runs the CLI commands shown in the exhibit for a production EC2 instance. The output indicates that the instance is running but the system status is impaired. Which action should the administrator take to recover the instance?

Accepted Answer

Configure EC2 Auto Recovery and wait for recovery.. EC2 Auto Recovery is the correct action when the system status check fails (impaired) because it automatically recovers the instance by moving it to new hardware while preserving its configuration. Option A (reboot) does not address underlying hardware issues. Option B (restart SAP services) is irrelevant to hardware impairment. Option D (stop and start) does move the instance to new hardware, but it is a manual process and not the recommended automated recovery method. EC2 Auto Recovery is designed specifically for this scenario.

Answer

Reboot the instance using the AWS console.

Answer

Restart the SAP application services.

Answer

Stop and start the instance.

Question 12

An SAP system uses Amazon EFS for shared file storage for transport directories. The system is deployed across multiple Availability Zones. Which EFS performance mode is most suitable for this workload?

Accepted Answer

General Purpose performance mode.. General Purpose performance mode is the most suitable for SAP transport directories because it provides the lowest latency for file operations, which is critical for the frequent, small I/O operations typical of SAP transport processes. Max I/O mode, while offering higher throughput for large sequential I/O, introduces higher latency that can degrade SAP performance. General Purpose mode is the default and recommended mode for most EFS workloads, including SAP shared file systems.

Answer

Max I/O performance mode.

Answer

Provisioned Throughput mode.

Answer

Bursting Throughput mode.

Question 13

A company is planning to run SAP HANA on AWS. Which three are best practices for configuring the EC2 instance for SAP HANA? (Choose THREE.)

Accepted Answer

Enable CPU hyper-threading. (Enable CPU hyper-threading) is correct. For SAP HANA, hyper-threading is enabled by default and recommended for production workloads as it improves performance. Option C (Use EBS-optimized instances) is correct because EBS-optimized instances provide dedicated throughput between EC2 and EBS, ensuring consistent storage performance for HANA data and log volumes. Option E (Use placement groups for HANA instances) is correct. Placement groups enable low-latency, high-throughput networking between instances in the same group, which is critical for HANA scale-out or HA setups. Option B (Use burstable instance types (T2/T3)) is incorrect because burstable instances rely on CPU credits and are not designed for sustained high CPU utilization; they are not suitable for production HANA workloads. Option D (Allocate swap space on the instance) is incorrect because SAP HANA relies on in-memory processing and swap space is not recommended; it can degrade performance and is typically disabled.

Answer

Use burstable instance types (T2/T3)

Answer

Allocate swap space on the instance

Question 14

An architect is designing a network topology for an SAP system on AWS. The SAP application servers must be placed in private subnets, and the web dispatchers must be accessible from the internet. Which configuration should the architect use to meet these requirements?

Accepted Answer

Place the web dispatchers in public subnets, the application servers in private subnets, and use a Network Load Balancer in front of the web dispatchers. Web dispatchers need direct internet accessibility, which is achieved by placing them in public subnets with an Internet Gateway route. The SAP application servers must remain in private subnets for security, and a Network Load Balancer (NLB) in front of the web dispatchers provides layer 4 load balancing and health checks without exposing the dispatchers' IPs directly, while preserving client IP for logging and security.

Answer

Place all SAP servers in public subnets and use security groups to restrict access

Answer

Place the web dispatchers in private subnets and use a NAT Gateway for internet access

Answer

Place all servers in private subnets and use an Application Load Balancer for internet access

Question 15

A company is migrating its SAP ERP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). They plan to use two EC2 instances in different Availability Zones with a shared file system. Which AWS service should they use to manage the failover of the virtual IP address?

Accepted Answer

Use an Elastic IP address and reassign it during failover using a script.. An Elastic IP address can be used as a virtual IP for SAP ASCS/ERS failover. By associating the Elastic IP with the active EC2 instance in one Availability Zone, and having a script (e.g., a watchdog process) automatically reassociate the Elastic IP to the standby instance upon failure, you can achieve virtual IP failover. This is a common pattern on AWS for SAP high availability when using shared file systems. Option B is incorrect because Amazon Route 53 provides DNS failover, not virtual IP management; DNS time-to-live (TTL) delays make it unsuitable for fast failover in SAP environments. Option C is incorrect because an Application Load Balancer operates at Layer 7 and does not provide a static IP for SAP protocols. Option D is incorrect because Classic Load Balancer is deprecated and lacks the required static IP failover capability.

Answer

Configure Amazon Route 53 with failover routing and health checks for the virtual IP.

Answer

Deploy an Application Load Balancer to route traffic to the active instance.

Answer

Set up a Classic Load Balancer with cross-zone load balancing enabled.

Question 16

A company is migrating a web application to AWS and wants to minimize latency for global users. Which AWS service should be used to cache static content at edge locations?

Accepted Answer

Amazon CloudFront. Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations, reducing latency for global users. AWS Global Accelerator (Option C) improves performance by routing traffic to optimal endpoints but does not cache content. Amazon S3 Transfer Acceleration (Option B) speeds up uploads to S3 but does not cache at edge for delivery. AWS WAF (Option A) is a web application firewall and does not cache content.

Answer

AWS WAF

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Global Accelerator

Question 17

Refer to the exhibit. An operations team uses this CloudFormation template to launch SAP application servers. After deployment, the application server fails to join the SAP system. The team verified that the security group allows outbound traffic to the SAP system. What is the MOST likely cause?

Accepted Answer

The `LatestAmiId` parameter is not defined in the template.. The template uses `!Ref LatestAmiId` which does not exist as a parameter; it should be a parameter or a mapping. Option A is wrong because the instance type is parameterized. Option B is wrong because the security group is referenced correctly. Option C is wrong because the user data script is base64 encoded correctly.

Answer

The instance type is not specified correctly.

Answer

The security group ID is not properly referenced.

Answer

The user data script is not base64 encoded correctly.

Question 18

A company is running an SAP HANA database on an EC2 instance with EBS volumes. The database experiences high write latency during peak hours. Which configuration change would most effectively reduce latency?

Accepted Answer

Use EBS io2 Block Express volumes with multi-attach enabled.. SAP HANA is a high-performance in-memory database that requires extremely low-latency storage for its data and log volumes. EBS io2 Block Express volumes provide up to 256,000 IOPS per volume with single-digit millisecond latency, and multi-attach enables a cluster configuration for high availability. This directly addresses high write latency during peak hours by delivering consistent, ultra-low latency performance that gp3 or larger instances cannot match.

Answer

Switch to gp3 EBS volumes with maximum throughput.

Answer

Increase the EC2 instance size to a compute-optimized type.

Answer

Migrate the data to instance store volumes.

Question 19

A company is migrating its SAP ERP system running on Oracle to SAP HANA on AWS. The system has a database size of 2 TB. During migration planning, the team needs to minimize downtime. Which strategy should be used?

Accepted Answer

Use SAP HANA System Replication to initially load data from the source SAP HANA (or migrate using SAP DMO with SUM) and then switch over.. SAP DMO (Database Migration Option) with SUM (Software Update Manager) is the recommended approach for migrating SAP systems to SAP HANA with minimal downtime. It performs a heterogeneous migration directly from Oracle to SAP HANA, using a combination of initial data load and subsequent delta replication to reduce the final cutover window. This method is specifically designed for SAP landscapes and supports near-zero downtime migration scenarios.

Answer

Take a full backup of Oracle, restore to SAP HANA, and then apply incremental logs.

Answer

Use the AWS Database Migration Service (DMS) to perform an online migration from Oracle to SAP HANA.

Answer

Perform an export/import using SAP tools while the source database is online.

Question 20

A company is deploying a new SAP HANA database on AWS and needs to ensure the EBS volumes are optimized for throughput. Which EBS volume type should be used for the HANA data and log volumes?

Accepted Answer

io2 Block Express. For SAP HANA data and log volumes, io2 Block Express (option B) is the correct choice because it provides the highest throughput and IOPS consistency required for SAP HANA's demanding workload. io2 Block Express supports up to 256,000 IOPS and 4,000 MB/s throughput per volume, with 99.999% durability, making it ideal for mission-critical SAP HANA databases on AWS.
