PAS-C01 Practice Test 30 — 15 Questions

Question 1

A company is migrating its SAP application from on-premises to AWS. The SAP application uses a shared file system (NFS) for transport directories. Which AWS service should the company use to replace the on-premises NFS?

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

Accepted Answer

Amazon EFS. Amazon EFS is a fully managed, scalable, elastic NFS file system for Linux-based workloads on AWS. It supports the NFSv4.1 protocol, making it a direct replacement for on-premises NFS shares used by SAP transport directories. EFS integrates natively with SAP-certified instances and provides shared, concurrent access across multiple EC2 instances and Availability Zones, which is essential for SAP transport directories.

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Answer

Amazon EBS

Question 2

A company runs SAP on AWS and needs to implement a disaster recovery (DR) strategy. The primary site is in us-east-1, and the DR site is in us-west-2. The database is SAP HANA. Which approach provides the lowest RPO?

Accepted Answer

SAP HANA system replication in synchronous mode across regions.. SAP HANA system replication in synchronous mode commits transactions on the primary only after the secondary acknowledges them, guaranteeing zero data loss (RPO ≈ 0) as long as the replication link is healthy. Although cross-region synchronous replication adds latency, it provides the lowest possible RPO, which is what the question asks for.

Answer

SAP HANA system replication in asynchronous mode.

Answer

Database backups to S3 and cross-region replication of S3 bucket.

Answer

EBS snapshots replicated to the DR region using cross-region snapshot copy.

Question 3

A company uses AWS CloudFormation to manage infrastructure. During an update, a stack fails to roll back and is left in UPDATE_ROLLBACK_FAILED state. The stack contains a DynamoDB table and a Lambda function. The operations team needs to fix the stack with minimal disruption. What should they do?

Accepted Answer

Use the ContinueUpdateRollback API to resume the rollback.. When a CloudFormation stack is in UPDATE_ROLLBACK_FAILED state, the recommended recovery action is to use the ContinueUpdateRollback API (or the AWS Management Console equivalent). This API instructs CloudFormation to skip the resources that failed to roll back and continue rolling back the remaining resources, bringing the stack to a consistent UPDATE_ROLLBACK_COMPLETE state. This approach minimizes disruption because it does not require deleting the stack or manually intervening with the DynamoDB table or Lambda function.

Answer

Manually delete the DynamoDB table and then retry the stack update.

Answer

Delete the stack and recreate it from the template.

Answer

Update the stack again with a different change set to bypass the failed resource.

Question 4

Which THREE factors should be considered when choosing a migration strategy for a legacy application to AWS? (Choose three.)

Accepted Answer

Total cost of ownership (TCO). Correct options: C, D, E. Total cost of ownership (TCO) is a key factor in migration decision-making. Business continuity requirements (RTO/RPO) ensure the application meets recovery objectives. Data sensitivity and compliance requirements dictate how data is handled during and after migration. Option A (Physical location) is less relevant because cloud migrations are not bound by physical location; servers can be migrated regardless of location. Option B (Programming language) alone does not determine the migration strategy; the application's architecture and dependencies are more important.

Answer

Physical location of the source server

Answer

Programming language used

Question 5

Match the SAP system type to its typical AWS deployment pattern.

Accepted Answer

SAP Production System: Typically deployed across multiple Availability Zones with SAP HANA System Replication for high availability.. SAP production systems require high availability and are typically deployed across multiple AZs. Development and sandbox systems have lower availability needs and are often in single AZs.

Answer

SAP Production System: Typically deployed in a single Availability Zone for cost optimization.

Answer

SAP Development System: Typically deployed across multiple Regions for disaster recovery.

Answer

SAP Sandbox System: Typically deployed across multiple Availability Zones with high availability.

Question 6

Which THREE metrics should an operations team monitor to detect performance issues in an SAP HANA database running on EC2?

Accepted Answer

CPU utilization. CPU utilization (A) is a core SAP HANA metric because HANA is an in-memory, highly parallelized database whose column-store operations and SQL execution consume significant CPU, so sustained high utilization directly signals query or workload performance degradation. Disk I/O read/write latency (B) must be monitored because HANA persists data and logs to disk (savepoints, redo log writes, and data loads from disk into memory), and elevated latency on EBS volumes stalls commits and checkpoints. Memory usage (D) is critical since HANA keeps the working data set in RAM; if memory pressure forces column-store tables to be unloaded or causes out-of-memory conditions, query performance drops sharply. Network packets in/out (C) is not a primary HANA performance indicator because packet counts alone don't reveal database-internal bottlenecks such as CPU saturation, memory eviction, or storage latency. Swap usage (E) is not applicable as a HANA performance metric because SAP HANA does not support swapping — it requires sufficient RAM and disables OS swap, so swap activity indicates a misconfiguration rather than a normal performance signal.

Answer

Network packets in/out

Answer

Swap usage

Question 7

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

Accepted Answer

AWS CloudTrail. AWS CloudTrail records every API call made to AWS services, capturing the identity of the caller, the time, the source IP, the request parameters, and the response. It is the canonical service for auditing API activity across an AWS account, including calls made by SAP automation, Lambda, or administrators.

Answer

AWS Config

Answer

Amazon CloudWatch Logs

Answer

VPC Flow Logs

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

Answer

Amazon CloudWatch

Answer

VPC Flow Logs

Question 9

A company runs SAP on AWS and needs to implement a disaster recovery strategy for their SAP NetWeaver system. The primary site is in us-east-1, and the DR site is in us-west-2. They want to minimize data loss and recovery time. Which approach meets these requirements?

Accepted Answer

Use SAP HANA System Replication in asynchronous mode across regions.. SAP HANA System Replication in asynchronous mode across regions is the correct approach because it provides near-zero recovery point objective (RPO) with minimal impact on primary system performance, while enabling rapid failover to the DR region in us-west-2. Asynchronous replication is suitable for cross-region scenarios where network latency would make synchronous mode impractical, and it meets the requirement to minimize both data loss and recovery time for SAP NetWeaver.

Answer

Use SAP HANA System Replication in synchronous mode across regions.

Answer

Use AWS Backup to back up the SAP HANA database and restore in us-west-2.

Answer

Use Amazon S3 cross-region replication for SAP HANA data files.

Question 10

A company is migrating a critical Oracle database to Amazon RDS for Oracle. They need to minimize downtime and ensure data consistency. Which AWS service should they use to perform an online migration with minimal impact?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication and can perform live migrations with minimal downtime. AWS Snowball is for offline data transfer. S3 Transfer Acceleration speeds up uploads to S3. Direct Connect establishes dedicated network connections but is not a migration service.

Answer

Answer

AWS Snowball

Answer

Amazon S3 Transfer Acceleration

Question 11

A company runs SAP on AWS and needs to automate the patching of SAP application servers. The solution should apply patches during a defined maintenance window and ensure high availability. What is the most efficient approach?

Accepted Answer

Use AWS Systems Manager Patch Manager with a maintenance window.. AWS Systems Manager Patch Manager with a maintenance window automates patching of SAP application servers, applies patches during defined windows, and ensures high availability by patching instances in a controlled manner. It is the most efficient and native AWS approach.

Answer

Update the CloudFormation stack to replace instances with new AMIs.

Answer

Use AWS Lambda to invoke Run Command on each instance sequentially.

Answer

Manually connect to each instance via SSH and apply patches.

Question 12

An organization is migrating a legacy application to AWS. The application requires a static IP address for client whitelisting. After migrating the application to an Application Load Balancer (ALB) with an Auto Scaling group, clients report connection failures. What should be done to resolve this issue?

Accepted Answer

Replace the ALB with a Network Load Balancer (NLB) and assign an Elastic IP.. An Application Load Balancer (ALB) does not support static IP addresses; its IP addresses can change. To provide a static IP for client whitelisting, you should replace the ALB with a Network Load Balancer (NLB), which supports Elastic IP addresses. This allows clients to whitelist a fixed IP. Placing an Nginx reverse proxy in front of the ALB with an Elastic IP is a workaround but adds complexity and is not the best practice. Assigning an Elastic IP directly to an ALB is not possible. Round-robin routing does not address the static IP requirement.

Answer

Place an Nginx reverse proxy in front of the ALB with an Elastic IP.

Answer

Assign an Elastic IP to the ALB.

Answer

Configure the ALB to use a round-robin routing algorithm.

Question 13

Which TWO AWS services can be used to monitor the health of SAP application servers? (Choose 2)

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch (D) is correct because it collects metrics, logs, and alarms from SAP application servers via the CloudWatch agent, enabling health monitoring of CPU, memory, disk, and custom SAP metrics. AWS Systems Manager (E) is correct because its tools such as Run Command, State Manager, and OpsCenter can check instance health, patch compliance, and run automation to remediate issues on SAP application servers. Amazon Route 53 (A) is a DNS and traffic-routing service, not an application server health monitor, though it can perform endpoint health checks for failover. Amazon S3 (B) is object storage and does not monitor server health. AWS CloudTrail (C) records API activity for auditing, not the runtime health of SAP application servers.

Answer

Amazon Route 53

Answer

Amazon S3

Answer

AWS CloudTrail

Question 14
