PAS-C01 Quick Quiz — 10 Questions

Question 1

A company is migrating a 10 TB SQL Server database to Amazon RDS for SQL Server using AWS DMS. The migration is taking longer than expected. Which TWO actions can improve the migration speed? (Choose two.)

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

Accepted Answer

Enable parallel loading by splitting tables into multiple tasks. Splitting tables into multiple DMS tasks enables parallel loading, which significantly reduces migration time by processing multiple tables concurrently. Option D is correct because increasing the DMS replication instance size provides more CPU and memory resources, allowing the instance to handle larger data volumes and higher throughput more efficiently.

Answer

Use a single DMS task with full LOB mode

Answer

Use S3 multipart upload for the data

Answer

Disable transaction logging on the source

Question 2

A company is running an SAP HANA database on an EC2 instance with EBS volumes. The operations team notices that the /hana/data filesystem is growing faster than expected and the available space is critically low. Which action should be taken to monitor the disk space usage proactively?

Accepted Answer

Publish custom CloudWatch metrics for disk space and set an alarm.. The correct option is C: publishing custom CloudWatch metrics for disk space and setting an alarm. CloudWatch does not natively collect OS-level filesystem metrics like /hana/data usage from EC2, so the CloudWatch agent must be installed to publish custom metrics (e.g., via the disk_used_percent metric in the CWAgent namespace), and an alarm can then proactively notify the team before space runs out. AWS Budgets (A) only tracks cost/spend, not actual disk utilization. AWS Config rules (B) evaluate resource configuration compliance, not filesystem space consumption. AWS Trusted Advisor (D) provides service-limit and best-practice checks but does not offer per-filesystem disk utilization monitoring for EC2 instances.

Answer

Configure AWS Budgets to alert on storage costs.

Answer

Use AWS Config rules to monitor disk space.

Answer

Create an AWS Trusted Advisor check for disk utilization.

Question 3

An SAP Basis administrator is migrating an SAP ERP system from an on-premises environment to AWS. The system uses an SAP HANA database. The migration must have minimal downtime. The administrator plans to use SAP HANA System Replication (HSR) to synchronize data to an AWS HANA instance. However, the network latency between on-premises and AWS is consistently around 50 ms. What should the administrator do to ensure that HSR can maintain synchronization without impacting source system performance?

Accepted Answer

Configure HSR in asynchronous mode with full sync disabled to avoid affecting source transaction performance.. With 50 ms network latency, synchronous replication would block source transactions while waiting for acknowledgment from the target, severely impacting performance. Asynchronous mode with full sync disabled allows HSR to send log buffers without waiting for the target to confirm, ensuring source system performance is unaffected while still maintaining eventual consistency for migration.

Answer

Use synchronous replication with a lower sync timeout setting to avoid blocking.

Answer

Keep synchronous replication but increase the replication timeout value in the HANA global.ini file.

Answer

Enable HANA delta merge operations during replication to reduce the amount of data transferred.

Question 4

An SAP administrator needs to implement a backup strategy for an SAP HANA database on AWS that provides point-in-time recovery (PITR) with minimal RPO. Which combination of AWS services should be used?

Accepted Answer

AWS Backup with Backint agent for SAP HANA. AWS Backup with the Backint agent for SAP HANA is the correct choice because it integrates directly with SAP HANA's native backup interface (Backint), enabling log backups and full/differential backups to Amazon S3. This combination supports point-in-time recovery (PITR) with minimal RPO by continuously backing up transaction logs, which is essential for meeting strict recovery objectives.

Answer

HANA backup to NFS on Amazon EFS

Answer

Amazon EBS snapshots of the HANA data volumes

Answer

Amazon S3 lifecycle policies

Question 5

A company runs SAP on AWS and has configured automated snapshots of EBS volumes for backup. The operations team discovers that the snapshots are not being deleted after the retention period. Which action should be taken to ensure snapshots are automatically deleted?

Accepted Answer

Use Amazon Data Lifecycle Manager to create a snapshot lifecycle policy.. Amazon Data Lifecycle Manager (DLM) is the native AWS service for automating the creation, retention, and deletion of EBS snapshots. By defining a lifecycle policy with a retention count or retention period, DLM automatically deregisters and deletes snapshots that exceed the schedule, which directly solves the problem of snapshots not being deleted.

Answer

Set an S3 Lifecycle policy on the snapshots.

Answer

Create a CloudWatch Events rule to invoke a Lambda function for deletion.

Answer

Configure retention policy directly on the EBS volume.

Question 6

Which TWO of the following are valid methods for monitoring SAP system performance on AWS? (Choose two.)

Accepted Answer

Configure SAP Solution Manager to send monitoring data to Amazon CloudWatch via the SAP Cloud Platform.. SAP Solution Manager can be configured to forward monitoring data to Amazon CloudWatch via the SAP Cloud Platform (now SAP BTP) using the Cloud Management Gateway or direct integration. This allows SAP-specific metrics like system load, work process usage, and response times to be visualized and alerted on in CloudWatch, enabling unified monitoring alongside AWS infrastructure metrics.

Answer

Enable AWS CloudTrail to capture system performance logs.

Answer

Use AWS Trusted Advisor to monitor real-time CPU utilization.

Answer

Use VPC Flow Logs to monitor database query performance.

Question 7

A company is planning to migrate its SAP ERP system to AWS. The system uses Oracle Database as its backend. The company wants to minimize licensing costs and administrative overhead. Which AWS database service is most suitable for this migration?

Accepted Answer

Amazon RDS for Oracle. Amazon RDS for Oracle is the most suitable choice because it directly supports Oracle Database, allowing the company to migrate its existing SAP ERP system with minimal re-architecture. It reduces administrative overhead through automated backups, patching, and replication, while still using the company's existing Oracle licenses (if they choose to bring their own license) to minimize licensing costs.

Answer

Amazon Redshift

Answer

Amazon DynamoDB

Answer

Amazon Aurora

Question 8

A company is running an SAP HANA database on an EC2 instance with an EBS gp3 volume. The workload is write-intensive and latency-sensitive. Which configuration change would provide the most consistent I/O performance?

Accepted Answer

Use an EBS io2 Block Express volume with provisioned IOPS. An SAP HANA database is extremely sensitive to I/O latency and requires consistent, high IOPS for write-intensive workloads. EBS io2 Block Express volumes provide up to 256,000 provisioned IOPS with 99.999% durability, delivering the predictable low-latency performance that gp3 volumes cannot guarantee under sustained write pressure. This makes D the correct choice for consistent I/O performance.

Answer

Switch to an EBS st1 (throughput-optimized HDD) volume

Answer

Enable EBS Multi-Attach for the gp3 volume

Answer

Increase the size of the existing gp3 volume to increase baseline throughput

Question 9

A company is planning to run SAP applications on AWS. The security team requires that all data transmitted between the SAP application servers and the SAP HANA database be encrypted in transit. The SAP HANA database is on an EC2 instance in the same VPC. The application servers are also in the same VPC. Which configuration should the company implement to meet the encryption requirement with minimal impact on performance?

Accepted Answer

Enable SAP HANA TLS/SSL encryption for the database connections. Enabling SAP HANA TLS/SSL encryption encrypts data in transit between application and database servers directly, with minimal performance impact as it is built into the SAP HANA client-server protocol. Option A is incorrect: AWS PrivateLink is used for private connectivity to services across VPCs or to AWS services, not for encrypting internal traffic within the same VPC, and introduces unnecessary complexity. Option C is incorrect: VPC peering connects separate VPCs but does not encrypt traffic by default; it also is not needed when both servers are in the same VPC. Option D is incorrect: a VPN connection adds network overhead and is designed for connectivity across networks or the internet, which is unnecessary and suboptimal for same-VPC communication.

Answer

Use AWS PrivateLink to connect the application to the database

Answer

Use VPC peering between the application and database subnets

Answer

Set up a VPN connection between the application and database servers

Question 10

An SAP system on AWS experiences intermittent performance issues. CloudWatch metrics show high CPU credit usage on the t3.large EC2 instance hosting the SAP application. The instance is configured as a 'standard' placement group. What is the MOST likely cause and recommended action?

Accepted Answer

The burstable instance is exhausting its CPU credits. Change to a non-burstable instance.. The t3.large is a burstable instance that earns CPU credits when idle and spends them when active. SAP applications often have sustained CPU demands that can exhaust the credit balance, causing performance throttling. Switching to a non-burstable instance (e.g., m5.large) provides consistent baseline CPU performance without credit-based limitations.

Answer

The instance size is too small. Move to a larger t3 instance.

Answer

The placement group is causing network bottlenecks. Move to a cluster placement group.

Answer

The EBS volume is not provisioned with enough IOPS. Increase the volume size.
