PAS-C01 Practice Test 50 — 15 Questions

Question 1

A company wants to use an SAP-certified AMI for a non-production SAP system to reduce deployment time. Which AWS service provides access to SAP-certified AMIs?

Accepted Answer

AWS Marketplace. AWS Marketplace is the correct service because it provides access to SAP-certified AMIs that have been pre-configured and validated by SAP for running SAP workloads on AWS. These AMIs are published by AWS and SAP partners, ensuring compliance with SAP's certification requirements and reducing deployment time for non-production systems.

Answer

EC2 Image Builder

Answer

AWS Systems Manager

Answer

AWS Service Catalog

Question 2

An SAP system on AWS uses a Classic Load Balancer to distribute traffic to web dispatchers. The system is experiencing intermittent timeouts. What is the most likely cause?

Accepted Answer

The load balancer idle timeout setting is too low.. The Classic Load Balancer has a default idle timeout of 60 seconds for TCP connections. If the SAP application or web dispatchers keep connections open longer than this without data transfer (e.g., during long-running reports or user think time), the load balancer will close the connection, causing intermittent timeouts. Increasing the idle timeout to match the application's keep-alive settings resolves this.

Answer

The security group for the load balancer is blocking traffic.

Answer

Sticky sessions are enabled on the load balancer.

Answer

The load balancer health check interval is too short.

Question 3

A company wants to automate the deployment of SAP systems on AWS. Which AWS service is most appropriate for infrastructure as code (IaC) for SAP?

Accepted Answer

AWS CloudFormation. AWS CloudFormation is the most appropriate service for infrastructure as code (IaC) for SAP because it allows you to define and provision AWS infrastructure declaratively using templates. This enables repeatable, version-controlled deployments of complex SAP landscapes, including EC2 instances, networking, storage, and security groups, which is critical for SAP's strict architectural requirements.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Question 4

A company is deploying SAP S/4HANA on AWS and needs to ensure that the system can survive a single Availability Zone failure. Which architecture meets this requirement?

Accepted Answer

Deploy an active-passive setup with the primary in one AZ and a standby in another AZ, using replication. An active-passive SAP HANA setup with the primary in one Availability Zone (AZ) and a standby in another AZ, using HANA System Replication (HSR) in synchronous mode, ensures zero data loss and automatic failover if a single AZ fails. This architecture meets the SAP S/4HANA requirement for high availability (HA) across AZs, as HSR replicates data at the database level, and the standby can take over within minutes.

Answer

Store the database files on Amazon S3 and mount them to the EC2 instance

Answer

Use Amazon RDS Multi-AZ for the SAP HANA database

Answer

Deploy a single EC2 instance in one Availability Zone with EBS snapshots

Question 5

A company has an SAP system running on AWS that uses an Application Load Balancer (ALB) to distribute traffic to multiple EC2 instances. The operations team notices that the ALB is returning 503 errors intermittently. Which of the following is the MOST likely cause?

Accepted Answer

The target instances are failing health checks.. An ALB returns HTTP 503 Service Unavailable when it has no healthy targets to route traffic to. If the EC2 instances behind the ALB are failing health checks (e.g., due to application errors, misconfigured health check path, or overloaded instances), the ALB marks them unhealthy and returns 503 to clients. Intermittent 503s typically indicate that targets are flapping between healthy and unhealthy states.

Answer

The security group attached to the ALB is blocking inbound traffic from the targets.

Answer

The ALB does not have enough capacity to handle the traffic.

Answer

The SSL certificate on the ALB has expired.

Question 6

An SAP Basis administrator needs to monitor the health of SAP application servers running on EC2. The administrator wants to receive alerts when a server becomes unreachable or when critical SAP processes stop. Which AWS service should be used to create a custom dashboard and set up alarms?

Accepted Answer

Amazon CloudWatch. CloudWatch can monitor EC2 instances and create alarms based on custom metrics, including process status. Option A is wrong because CloudTrail is for auditing API calls. Option C is wrong because Config is for resource compliance. Option D is wrong because Trusted Advisor provides best-practice checks but not custom monitoring.

Answer

AWS CloudTrail

Answer

AWS Config

Answer

AWS Trusted Advisor

Question 7

A company is migrating an SAP HANA database to AWS using the SAP HANA System Replication (HSR) with asynchronous mode. The database size is 5 TB. The migration must be completed within 8 hours. Which AWS resource is most critical to ensure the initial data synchronization completes within the time window?

Accepted Answer

EC2 instance with high network bandwidth and Enhanced Networking. The initial data synchronization in SAP HANA System Replication (HSR) is network-intensive, as it transfers the full 5 TB database from the source to the target. High network bandwidth (e.g., using Enhanced Networking with ENA) directly reduces transfer time, making it the most critical resource to meet the 8-hour window. While EBS gp3 volumes (Option C) provide sufficient IOPS, they are secondary because the bottleneck is network throughput, not storage performance. Option B (EBS snapshots) is not used in HSR, and Option D (S3 multipart upload) is irrelevant for HSR.

Answer

EBS snapshots for the initial data copy

Answer

EBS gp3 volumes with sufficient IOPS

Answer

Amazon S3 multipart upload for initial data

Question 8

An administrator runs the command shown in the exhibit to check the status of an EBS volume attached to an SAP HANA instance. The volume is 200 GB gp3 and is attached to instance i-0a1b2c3d4e5f67890. The administrator wants to increase the I/O performance. The volume is currently set to 3000 IOPS (baseline for gp3). Which action will increase IOPS without downtime?

Accepted Answer

Modify the volume's IOPS setting to a higher value (e.g., 6000) using the modify-volume API.. For an EBS gp3 volume, IOPS and throughput can be modified independently of volume size using the ModifyVolume API (or 'aws ec2 modify-volume --iops'). gp3 allows IOPS from 3,000 to 16,000 and throughput from 125 to 1,000 MiB/s, and changes take effect without detaching the volume or downtime. Increasing IOPS from 3,000 to 6,000 is a valid online modification.

Answer

Detach the volume, increase the size to 500 GB, and reattach.

Answer

Modify the volume type to io2 Block Express and increase IOPS.

Answer

Take a snapshot of the volume and create a new volume with higher IOPS from the snapshot.

Question 9

A company is migrating its SAP landscape to AWS and has a requirement to use existing software licenses to reduce costs. Which AWS pricing model should be used?

Accepted Answer

Dedicated Hosts. Dedicated Hosts provide a physical server dedicated to a single customer, which allows you to use your existing software licenses, including Windows Server and SQL Server, and also SAP licenses that are tied to physical cores or sockets. This helps reduce costs by leveraging bring-your-own-license (BYOL).

Answer

Compute Savings Plans

Answer

Reserved Instances (RI)

Answer

Dedicated Instances

Question 10

A company is migrating a multi-tier web application to AWS. The web tier uses sticky sessions. The application tier uses a shared session store. Which architecture ensures high availability and scalability?

Accepted Answer

Use an Application Load Balancer with sticky sessions and Amazon ElastiCache for session storage.. Using an Application Load Balancer (ALB) with sticky sessions and Amazon ElastiCache for session storage ensures high availability and scalability. Sticky sessions keep users on the same instance for session duration, while ElastiCache provides a shared, highly available session store that survives instance failures.

Answer

Use an Application Load Balancer with sticky sessions enabled, and store sessions on each EC2 instance.

Answer

Use a Classic Load Balancer with sticky sessions and store sessions in RDS.

Answer

Use Amazon CloudFront with origin failover and store sessions in S3.

Question 11

An SAP system administrator needs to monitor the health of Amazon RDS for SAP ASE database instances. Which TWO CloudWatch metrics should be used to detect if the database is under memory pressure?

Accepted Answer

`FreeableMemory`. FreeableMemory (option C) is correct because it reports the amount of available RAM on the RDS instance, so a steadily declining or very low value directly signals that the SAP ASE database is running short of memory. SwapUsage (option D) is correct because rising swap activity indicates the instance has exhausted physical memory and is paging to disk, which is a classic symptom of memory pressure. Together these two CloudWatch metrics give the clearest picture of memory exhaustion on an Amazon RDS for SAP ASE instance. WriteIOPS (A) and ReadIOPS (B) measure disk I/O throughput and say nothing about memory availability, and DatabaseConnections (E) only reflects the number of active sessions, which can be high or low regardless of memory pressure.

Answer

`WriteIOPS`

Answer

`ReadIOPS`

Answer

`DatabaseConnections`

Question 12

A company is running SAP on AWS and wants to implement a patching strategy for the operating system of EC2 instances with minimal downtime. The instances are part of an Auto Scaling group. Which of the following approaches is the MOST appropriate?

Accepted Answer

Create a new Amazon Machine Image (AMI) with the latest patches, update the launch configuration, and perform a rolling update of the Auto Scaling group.. Creating a new AMI with the latest patches, updating the launch configuration, and performing a rolling update of the Auto Scaling group replaces instances with patched AMIs without downtime. Option A is incorrect because applying patches directly to running instances using AWS Systems Manager Patch Manager requires reboots, causing downtime for each instance. Option B is incorrect because stopping the Auto Scaling group stops all instances, resulting in full downtime. Option C is incorrect because using Patch Manager to patch all instances at the same time during a maintenance window would cause simultaneous reboots, leading to downtime.

Answer

Apply patches directly to the running instances using AWS Systems Manager Patch Manager and reboot each instance one at a time.

Answer

Stop the Auto Scaling group, patch the instances, and start the group again.

Answer

Use AWS Systems Manager Patch Manager to patch all instances at the same time during a maintenance window.

Question 13

Which THREE metrics should be monitored in Amazon CloudWatch to proactively identify performance issues in an SAP NetWeaver application server? (Choose three.)

Accepted Answer

CPUUtilization. CPUUtilization (B) is a core EC2 metric published by default to CloudWatch and directly reflects the compute load on the SAP NetWeaver application server, so sustained high values signal CPU bottlenecks that degrade dialog and background work processes. Memory utilization via the CloudWatch Agent (C) is essential because SAP NetWeaver relies heavily on memory (heap, extended memory, and buffers), and the default EC2 metrics do not expose OS-level memory usage, so the agent is required to detect swapping or memory pressure proactively. DiskQueueDepth (E) measures the number of outstanding I/O requests on an EBS volume, and rising values indicate storage latency that can stall SAP database and work-process I/O, making it a valid proactive performance indicator. S3 request metrics (A) only track object storage access patterns and have no bearing on the runtime performance of an SAP NetWeaver application server. VPC Flow Logs (D) capture IP traffic metadata for network troubleshooting and security analysis, not application server performance metrics, so they do not belong here.

Answer

S3 request metrics

Answer

VPC Flow Logs

Question 14

A company is migrating an SAP ERP system on Oracle to SAP HANA on AWS. The migration requires near-zero downtime. The company has a test environment that can be used for the migration rehearsal. The SAP HANA database will be 3 TB. Which migration approach should the company use to achieve near-zero downtime?

Accepted Answer

Use SAP Software Update Manager (SUM) with Database Migration Option (DMO).. SAP Software Update Manager (SUM) with Database Migration Option (DMO) is the correct approach because it combines the SAP system upgrade and the migration from Oracle to SAP HANA into a single process, leveraging SAP's own tools to minimize downtime. DMO uses a trigger-based replication mechanism that can achieve near-zero downtime by keeping the source Oracle database and target SAP HANA database synchronized during the migration window, which is critical for a 3 TB database where traditional backup-restore would exceed downtime limits.

Answer

Use AWS Database Migration Service (DMS) for ongoing replication.

Answer

Perform a full backup of the Oracle database and restore to SAP HANA.

Answer

Use SAP HANA Studio to export the Oracle schema and import into HANA.

Question 15

A company is running SAP HANA on an EC2 instance. The storage is provided by multiple EBS volumes. Which THREE considerations are important when configuring EBS volumes for SAP HANA? (Choose THREE.)

Accepted Answer

Use RAID 0 striping across multiple EBS volumes to increase throughput.. Option A is correct because SAP HANA is an in-memory database that generates heavy sequential and random I/O, and RAID 0 striping across multiple EBS volumes aggregates their IOPS and throughput into a single logical device, which is the AWS-recommended way to reach HANA's required performance levels. Option C is correct because HANA writes to data volumes and log volumes with different access patterns, and placing them on separate EBS volumes prevents log write latency from being degraded by data I/O contention, which is critical for HANA's recovery point objective. Option E is correct because EBS performance is provisioned per volume, so each volume must be sized with enough IOPS (for example, using io1/io2 or gp3 with provisioned IOPS) to satisfy SAP HANA's KPIs, since under-provisioned volumes cause unacceptable database latency. Option B is not appropriate because gp2 burst credits are a shared, best-effort mechanism that cannot guarantee sustained high IOPS for a production HANA workload, and SAP guidance favors provisioned-performance volumes. Option D is not appropriate because there is no generic 'EBS bursting' feature to enable on all volumes; burst behavior is specific to certain volume types and cannot be relied upon to deliver guaranteed throughput for HANA.

Answer

Use gp2 volumes with burst credits to handle peak IOPS.

Answer

Enable EBS bursting for all volumes to ensure high throughput.
