PAS-C01 Practice Test 12 — 15 Questions

Question 1

An SAP NetWeaver system on AWS is configured with a shared file system between the application servers. Which AWS storage service should be used for this shared file system?

Accepted Answer

Amazon EFS. Amazon EFS is the correct choice because it provides a fully managed, NFS-based shared file system that can be mounted concurrently by multiple EC2 instances, making it ideal for SAP NetWeaver application servers that require a common file system for shared data such as transport directories, logs, and profile files. EFS supports the NFSv4.1 and NFSv4.0 protocols, ensuring POSIX-compliant file locking and consistency across the cluster.

Answer

AWS Storage Gateway File Gateway

Answer

Amazon S3

Answer

Amazon EBS with multi-attach

Question 2

A company runs a stateful web application on EC2 instances in an Auto Scaling group with a dynamic scaling policy based on CPU utilization. The application maintains session state in memory on each instance. Users report that they are frequently logged out and lose their session data during scaling events. What should the company do to resolve this issue?

Accepted Answer

Modify the application to store session state in an Amazon ElastiCache cluster. Storing session state externally in ElastiCache decouples session data from individual EC2 instances. This ensures that when instances are terminated or added during scaling events, users retain their session state regardless of which instance serves their request. ElastiCache provides a low-latency, in-memory cache that is ideal for session persistence in stateful web applications.

Answer

Change the scaling policy to a simple scaling policy instead of dynamic scaling

Answer

Enable sticky sessions (session affinity) on the Application Load Balancer

Answer

Increase the cooldown period for the Auto Scaling group

Question 3

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.. To ensure SAP system availability if an entire Availability Zone fails, the most critical step is to enable HANA system replication for the database and configure ASCS with enqueue replication across the two AZs. This provides automatic failover for both the database and the central services, which are single points of failure. Without these, the system would not survive an AZ outage.

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 4

A company uses AWS Lambda functions with reserved concurrency to process messages from an SQS queue. The operations team notices that the Lambda function sometimes throttles, causing messages to remain in the queue. What is the MOST likely cause and solution?

Accepted Answer

The reserved concurrency is set too low; increase the reserved concurrency for the function.. Lambda throttling occurs when the reserved concurrency limit is reached, preventing the function from processing new invocations. Since the function uses reserved concurrency, setting it too low restricts the number of concurrent executions, causing SQS messages to remain in the queue until concurrency becomes available. Increasing the reserved concurrency allows more parallel invocations, reducing throttling and improving message processing throughput.

Answer

The SQS visibility timeout is too short; increase it.

Answer

The Lambda function's dead-letter queue (DLQ) is not configured; set up a DLQ.

Answer

The SQS queue's redrive policy is too aggressive; reduce the maxReceiveCount.

Question 5

A company is migrating an SAP S/4HANA system to AWS. The migration strategy involves using SAP HANA System Replication (HSR) to replicate the source HANA database to an EC2 instance running HANA. During the final cutover, the replication link breaks and the target database becomes inconsistent. What should the migration team do to recover?

Accepted Answer

Perform a full HSR initial snapshot from the source to the target. When SAP HANA System Replication (HSR) link breaks and the target database becomes inconsistent, the most reliable recovery is to perform a full HSR initial snapshot from the source to the target. This re-establishes the replication and ensures the target is consistent with the source. Delta snapshots are only possible if the replication link is intact and the target is not too far behind.

Answer

Restart HSR with a delta snapshot from the source

Answer

Restore the target database from an AWS Backup

Answer

Use AWS DMS to replicate remaining changes

Question 6

An SAP administrator needs to ensure that all EC2 instances in the SAP landscape have the correct patches and configurations. Which AWS service can be used to automate OS patch management?

Accepted Answer

AWS Systems Manager Patch Manager. AWS Systems Manager Patch Manager automates the process of patching operating systems and applications across EC2 instances (and on-premises servers) using patch baselines, maintenance windows, and compliance reporting. It is the purpose-built AWS service for OS patch management at scale, making it the correct choice for an SAP landscape.

Answer

AWS CloudFormation

Answer

AWS OpsWorks

Answer

AWS Config

Question 7

A company runs SAP S/4HANA on AWS with a large HANA database (10 TB). The database uses EBS gp3 volumes. The system experiences performance degradation due to high disk I/O. The architect decides to migrate to EBS io2 Block Express volumes. Which THREE factors should the architect consider when planning the migration?

Accepted Answer

The maximum IOPS per volume supported by io2 Block Express is 256,000.. Io2 Block Express volumes support a maximum IOPS of 256,000 per volume, which is significantly higher than the 16,000 IOPS limit of gp3. This high IOPS capability is critical for large SAP HANA databases (10 TB) that experience performance degradation due to high disk I/O, as it allows the database to handle bursty workloads without throttling.

Answer

SAP HANA supports RAID 0 across multiple io2 volumes without additional software.

Answer

io2 Block Express volumes can be attached to multiple EC2 instances simultaneously using EBS Multi-Attach.

Question 8

A company is running SAP HANA on an EC2 instance with multiple EBS volumes for data and log. The instance is experiencing high write latency on the log volume. The administrator notices that the log volume is a gp2 EBS volume with 1,000 GB size and 3,000 IOPS baseline. The average write IOPS to the log volume is 4,000, with peaks up to 5,500. Which action should the administrator take to resolve the latency?

Accepted Answer

Replace the gp2 volume with an io2 Block Express volume provisioned at 6,000 IOPS.. The gp2 volume's baseline IOPS is 3,000, but the log volume requires an average of 4,000 write IOPS with peaks up to 5,500, which exceeds the burst balance, causing latency. Replacing with an io2 Block Express volume provisioned at 6,000 IOPS provides consistent high IOPS and low latency, ideal for SAP HANA log volumes. Option B is incorrect because st1 volumes are throughput-optimized, not IOPS-optimized, and would not address the IOPS bottleneck. Option C is incorrect because striping additional gp2 volumes adds complexity and still relies on burst performance, which may not sustain the required IOPS. Option D is incorrect because while increasing gp2 size to 2,000 GB doubles baseline IOPS to 6,000, gp2 still uses a burst model; if the burst balance is depleted, latency can occur. io2 Block Express provides provisioned, consistent performance without bursting.

Answer

Change the volume type to st1 (throughput optimized) to improve throughput.

Answer

Add a second log volume and stripe them using LVM.

Answer

Increase the gp2 volume size to 2,000 GB to double the baseline IOPS.

Question 9

A company is migrating a SAP system to AWS and needs to ensure that the SAP license is compliant. The current license is based on the number of users. What is the correct approach for SAP licensing on AWS?

Accepted Answer

Bring your own SAP license to AWS and ensure compliance with the user-based metric.. SAP licensing on AWS follows the same model as on-premises; the customer must license the SAP software based on users or engine size. Option A is wrong because AWS does not offer bring-your-own-license for all SAP products, but it is allowed. Option B is wrong because AWS does not include SAP licenses. Option D is wrong because AWS does not provide SAP licenses.

Answer

Purchase a SAP license through AWS Marketplace that is included in the EC2 instance cost.

Answer

Use AWS License Manager to track the number of vCPUs and report to SAP.

Answer

Use AWS License Manager to convert the user-based license to a processor-based license.

Question 10

A company is planning to run SAP HANA on AWS. What is the recommended practice for sizing the EC2 instance for SAP HANA?

Accepted Answer

Select an instance type from the SAP HANA certified list on AWS. AWS requires SAP HANA to run only on EC2 instance types that have been certified by SAP and listed in the SAP HANA Hardware Directory. This certification ensures the instance meets SAP's strict memory, CPU, and I/O requirements for production workloads. Selecting a non-certified instance can lead to unsupported configurations, performance issues, and loss of SAP support.

Answer

Choose an instance with the highest network bandwidth

Answer

Choose an instance with the highest vCPU count

Answer

Choose an instance with the most memory available

Question 11

A company is migrating its SAP system to AWS and needs to assess the current on-premises environment for compatibility. Which AWS tool should be used to collect system configuration and usage data for SAP systems?

Accepted Answer

AWS Application Discovery Service. AWS Application Discovery Service (option A) is the correct tool for collecting system configuration and usage data from on-premises environments, including SAP systems, to inform migration planning. AWS Migration Hub (option B) tracks migration progress across tools but does not perform data collection. AWS Systems Manager (option C) is for management and operations, not discovery. AWS Server Migration Service (option D) automates server replication but does not collect configuration or usage data.

Answer

AWS Migration Hub

Answer

AWS Systems Manager

Answer

AWS Server Migration Service (AWS SMS)

Question 12

An SAP administrator runs the AWS CLI command shown in the exhibit to describe an EBS volume attached to an EC2 instance running SAP HANA. The instance is in the us-east-1a Availability Zone. The administrator needs to create a volume in us-east-1b and copy the data from the existing volume. What is the most efficient way to achieve this?

Accepted Answer

Create a snapshot of the volume and then create a new volume in us-east-1b from the snapshot. EBS snapshots are stored in Amazon S3 and are region-scoped but can be used to create new EBS volumes in any Availability Zone within the same region. Creating a snapshot of the us-east-1a volume and then creating a new volume in us-east-1b from that snapshot is the most efficient, native AWS method to copy data across AZs. This avoids network transfer overhead and leverages AWS's internal snapshot copy mechanism.

Answer

Use rsync to copy data from the instance to a new volume in us-east-1b over the network

Answer

Detach the volume from the instance and attach it to an instance in us-east-1b

Answer

Create an AMI from the instance and launch a new instance in us-east-1b

Question 13

An SAP administrator is troubleshooting a performance issue on an SAP HANA database running on an r5.8xlarge EC2 instance. The application team reports that queries are slow during peak hours. CloudWatch metrics show high CPU utilization and high memory usage. Which instance type should the administrator choose to improve performance?

Accepted Answer

r5.24xlarge. The r5.24xlarge provides more CPU and memory than r5.8xlarge. Option A (m5.24xlarge) is wrong because m5 instances are general purpose and may not have enough memory for SAP HANA. Option B (t3.2xlarge) is wrong because t3 instances are burstable and not suitable for production HANA workloads. Option D (r5b.8xlarge) is wrong because while r5b is similar, it does not provide the additional CPU and memory required; upgrading to a larger instance size is more appropriate.

Answer

m5.24xlarge

Answer

t3.2xlarge

Answer

r5b.8xlarge

Question 14

Which TWO AWS services can be used to automate the deployment of SAP infrastructure using infrastructure as code? (Choose 2)

Accepted Answer

AWS Service Catalog. AWS CloudFormation (B) is correct because it is AWS's native infrastructure-as-code service that lets you define SAP infrastructure (VPCs, EC2 instances, EBS volumes, security groups, etc.) in JSON/YAML templates and deploy them repeatably and automatically. AWS Service Catalog (A) is correct because it lets administrators create and govern curated CloudFormation-based products (portfolios) that end users can launch on demand, which is a standard way to automate and standardize SAP infrastructure deployments with IaC under centralized control. AWS OpsWorks (C) is a configuration-management service (Chef/Puppet) focused on application stack configuration rather than declarative infrastructure provisioning, so it is not the intended IaC deployment service here. AWS CodeDeploy (D) automates application code deployments to EC2/on-premises/lambda, not infrastructure provisioning. AWS Elastic Beanstalk (E) is a PaaS for deploying web applications and does not provision arbitrary SAP infrastructure as code.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Elastic Beanstalk

Question 15

An organization has an SAP S/4HANA system running on AWS. The system uses a multi-node HANA scale-out configuration. The company wants to implement a disaster recovery solution with an RPO of less than 1 hour and an RTO of less than 2 hours. The DR site is in a different AWS Region. Which THREE components should be included in the DR plan?

Accepted Answer

Cross-region Amazon Machine Image (AMI) copies for the SAP application servers.. Option A is correct because copying AMIs of the SAP application servers to the DR Region provides pre-built, bootable server images so application servers can be launched quickly in the DR Region, which supports the RTO of under 2 hours. Option C is correct because an Amazon Route 53 DNS failover routing policy automatically redirects client traffic to the DR Region when the primary Region's health check fails, enabling timely failover. Option D is correct because SAP HANA System Replication in asynchronous mode continuously ships redo logs to the DR Region, achieving an RPO well under 1 hour for the multi-node scale-out HANA database. Option B is not appropriate because AWS Global Accelerator optimizes traffic routing for performance and availability using anycast IPs, but it does not provide the DNS-based regional failover mechanism needed here. Option E is not appropriate because daily EBS snapshots copied to the DR Region yield an RPO of up to 24 hours, which fails to meet the required RPO of less than 1 hour.

Answer

AWS Global Accelerator to route traffic to the closest Region.

Answer

Daily EBS snapshots of all volumes copied to the DR Region.
