PAS-C01 Practice Test 2 — 10 Questions

Question 1

An SAP system administrator needs to monitor the CPU utilization of an EC2 instance running SAP NetWeaver and set an alarm when it exceeds 90% for 5 minutes. Which AWS service should they use?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch is the correct service because it provides detailed monitoring of EC2 instances, including CPU utilization metrics, and allows you to set CloudWatch Alarms that trigger when a metric exceeds a specified threshold (e.g., 90%) for a given number of consecutive evaluation periods (e.g., 5 minutes). This is the native AWS service designed for performance monitoring and alerting.

Answer

AWS CloudTrail

Answer

AWS Trusted Advisor

Answer

AWS Config

Question 2

An SAP administrator runs the AWS CLI command shown in the exhibit to check the status of a production HANA instance. The output shows the instance is running in us-east-1a. However, the SAP application team reports that the HANA database is not responding. What should the administrator check next to diagnose the issue?

Accepted Answer

The HANA database service is not running on the instance. The AWS CLI command only checks the EC2 instance state (e.g., 'running'), not the status of the HANA database service itself. Even if the instance is running, the HANA database service (hdbnameserver, hdbindexserver, etc.) may have crashed, failed to start, or been stopped. The administrator should SSH into the instance and run commands like 'systemctl status hdbindexserver' or 'sapcontrol -nr <instance_number> -function GetProcessList' to verify the HANA service status.

Answer

The EBS volumes are detached from the instance

Answer

The instance state is 'running' so no issue with the instance

Answer

The security group does not allow inbound traffic to the database port

Question 3

A company is running an SAP HANA database on an r5.8xlarge EC2 instance. The database experiences high memory pressure, and they want to add more memory without downtime. What should they do?

Accepted Answer

Modify the instance type to r5.12xlarge while the instance is running.. You can modify the instance type of a running EC2 instance without stopping it, provided the new type is compatible with the current configuration. In this case, changing from r5.8xlarge to r5.12xlarge increases memory from 256 GiB to 384 GiB, and both are in the same instance family, supporting live resizing. This allows the SAP HANA database to add memory without downtime, addressing high memory pressure.

Answer

Use AWS License Manager to add more memory to the instance.

Answer

Use Amazon RDS for SAP HANA to automatically scale memory.

Answer

Stop the instance and change the instance type to u-6tb1.112xlarge.

Question 4

An SAP administrator is migrating an SAP Business Suite system from on-premises to AWS. The system uses an Oracle database that is 2 TB in size. The bandwidth between the on-premises data center and AWS is limited to 100 Mbps. The migration must be completed within a weekend (48 hours). The administrator decides to use AWS DMS for ongoing replication after an initial full load. However, the initial full load takes too long. What should the administrator do to accelerate the initial full load?

Accepted Answer

Use AWS Snowball Edge to physically transfer the database backup to AWS, then restore and use DMS for ongoing replication.. The 2 TB database over a 100 Mbps link would take approximately 47 hours just for the transfer (2 TB * 8 / 100 Mbps / 3600 seconds ≈ 47.6 hours), leaving no time for restore and validation. AWS Snowball Edge provides a physical shipping alternative that bypasses network bandwidth constraints entirely, allowing the full load to be completed within the weekend. After restoring the backup from Snowball, AWS DMS can be used for ongoing replication of changes.

Answer

Disable encryption on the database backup to reduce transfer overhead.

Answer

Increase the size of the DMS replication instance to the largest available.

Answer

Use Amazon S3 Transfer Acceleration to speed up the upload.

Question 5

A company runs SAP ERP 6.0 on an Oracle database on EC2. The system is experiencing high CPU usage on the database server during peak hours. Analysis shows that the CPU is consumed by log writes. Which configuration change can reduce CPU usage?

Accepted Answer

Increase the Oracle log buffer size to reduce the number of log write operations.. High CPU usage from log writes indicates that the database is spending excessive CPU cycles on writing redo log entries to disk. Increasing the Oracle log buffer size reduces the frequency of log write operations by allowing more redo data to accumulate before a write is triggered, thereby lowering CPU overhead. This directly addresses the root cause without changing storage or compute capacity.

Answer

Disable archiving of redo logs.

Answer

Switch from EBS gp3 to io2 Block Express volumes.

Answer

Upgrade to a larger EC2 instance type with more vCPUs.

Question 6

A company is running SAP HANA on AWS and needs to ensure high availability for the database. Which AWS service should be used to automatically recover the HANA primary instance in case of an instance failure?

Accepted Answer

Amazon Route 53 health checks and failover routing. Amazon Route 53 health checks and failover routing can automatically detect an instance failure and route traffic to a standby HANA primary instance. By configuring a Route 53 DNS failover record with health checks against the primary instance, DNS resolution is updated to point to the secondary instance when the primary becomes unhealthy, enabling automated recovery without manual intervention.

Answer

Amazon CloudWatch alarms

Answer

AWS CloudFormation custom resources

Answer

AWS Lambda functions

Question 7

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 8

A company is migrating its SAP HANA database to AWS and needs to choose the most appropriate EC2 instance type. The workload requires high memory bandwidth and is CPU-intensive. Which instance family would best meet these requirements?

Accepted Answer

X1e instance family. The X1e instance family is purpose-built for high-memory, CPU-intensive SAP HANA workloads, offering up to 3.9 TB of memory and high memory bandwidth per vCPU. This aligns with SAP HANA's requirement for large in-memory databases and compute-intensive processing, making D the correct choice.

Answer

M5 instance family

Answer

I3 instance family

Answer

C5 instance family

Question 9

Which TWO are required considerations when sizing an SAP HANA instance on AWS for a production environment? (Choose two.)

Accepted Answer

Ensure the instance has enough memory to hold the HANA data in memory (RAM:data ratio).. SAP HANA is an in-memory database that requires all active data to reside in RAM. The RAM:data ratio must be carefully sized to ensure the instance has enough memory to hold the HANA data and log volumes in memory, typically with a 1:4 or 1:8 ratio depending on compression and workload. AWS provides specific instance types (e.g., x1e, u-6tb1) certified for SAP HANA that meet these memory requirements.

Answer

Provision instance store volumes for HANA data and log areas.

Answer

Purchase Reserved Instances for the HANA server to reduce costs.

Answer

Select an RDS instance type that supports SAP HANA.

Question 10

A company is running SAP on AWS and needs to design a disaster recovery (DR) solution with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 4 hours. The primary region is us-east-1 and the DR region is us-west-2. The SAP application uses an SAP HANA database with a size of 2 TB. Which combination of AWS services should be used to meet the DR requirements most cost-effectively?

Accepted Answer

Configure HANA System Replication (HSR) across regions and use a standby HANA instance in us-west-2 with a smaller instance size.. HANA System Replication (HSR) is the native SAP HANA replication technology that can achieve an RPO of 15 minutes or less by asynchronously replicating data across regions. By using a smaller standby instance in us-west-2, the solution meets the RTO of 4 hours (since the standby can be scaled up or promoted quickly) while minimizing ongoing DR costs. This approach is purpose-built for SAP HANA and avoids the overhead of third-party tools or backup-based restores.

Answer

Use AWS Database Migration Service (DMS) with continuous replication from the primary HANA database to a target in us-west-2.

Answer

Use AWS Backup with continuous backups and cross-region copy to achieve RPO of 15 minutes.

Answer

Use AWS Backup to take hourly backups of the HANA database and restore in us-west-2 during a disaster.
