PAS-C01 Technology Practice Test 5 — 15 Questions

Question 1

A company runs SAP HANA on AWS using a scale-up configuration. The system is experiencing high CPU utilization on the HANA server during peak load. The SAP administrator wants to add more CPU resources without disruption. Which action should be taken?

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

Accepted Answer

Add an additional HANA node to create a scale-out configuration and distribute the load.. Adding an additional HANA node to create a scale-out configuration allows the system to distribute the workload across multiple nodes, providing additional CPU resources without downtime. SAP HANA supports scale-out configurations where new nodes can be added online using the 'ALTER SYSTEM ADD WORKER' command, enabling CPU scaling without restarting the existing system.

Answer

Enable Multi-AZ deployment for high availability.

Answer

Change the EC2 instance type to a larger size using the AWS Management Console.

Answer

Increase the provisioned IOPS on the EBS volumes.

Question 2

A company is designing an SAP HANA disaster recovery solution on AWS. The primary system is in us-east-1, and the DR system must be in us-west-2. The RPO is 15 minutes, and RTO is 1 hour. Which TWO approaches meet these requirements? (Choose TWO.)

Accepted Answer

Use AWS Database Migration Service (DMS) with ongoing replication from the primary HANA database to a target HANA database in us-west-2.. Option A is correct because AWS DMS supports ongoing (change data capture) replication from an SAP HANA source to a target HANA database, continuously applying changes so the DR copy stays within the 15-minute RPO and can be promoted within the 1-hour RTO. Option D is correct because SAP HANA System Replication (HSR) is SAP's native mechanism for continuously shipping redo log changes to a secondary HANA instance, and in a multi-tier or delta-data-shipping configuration it keeps the secondary in us-west-2 within the 15-minute RPO while allowing a fast takeover that satisfies the 1-hour RTO. Option B is not appropriate because 15-minute EBS snapshots only capture point-in-time copies, so the actual data loss can approach 15 minutes or more and restoring volumes plus recovering HANA typically exceeds the 1-hour RTO. Option C does not meet the requirements because S3 Cross-Region Replication only copies backup files asynchronously, so the DR database must still be rebuilt from those backups, which cannot reliably achieve a 15-minute RPO or 1-hour RTO. Option E is incorrect because AWS MGN replicates whole servers at the block level for migration, not for continuous database-consistent HANA replication, and it does not provide the application-consistent, near-real-time DR needed here.

Answer

Take EBS snapshots of HANA data volumes every 15 minutes and copy them to us-west-2.

Answer

Use Amazon S3 Cross-Region Replication to copy HANA backup files to us-west-2.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire HANA server to us-west-2.

Question 3

An SAP system running on AWS is experiencing high latency in the application layer. The system uses a load balancer to distribute traffic across multiple EC2 instances. Which THREE actions could help diagnose the latency issue? (Choose THREE.)

Accepted Answer

Monitor the EC2 instance CPU and memory utilization using Amazon CloudWatch metrics.. Option A is correct because Amazon CloudWatch provides EC2 CPUUtilization and memory metrics (memory via the CloudWatch agent) that reveal whether application-layer latency stems from resource saturation on the instances behind the load balancer. Option C is correct because enabling detailed monitoring changes EC2 metrics from 5-minute to 1-minute granularity, giving the finer time resolution needed to correlate latency spikes with instance behavior. Option D is correct because Application Load Balancer access logs record per-request fields such as target_processing_time, response_time, and elb_status_code, which pinpoint slow requests and backend targets causing the latency. Option B does not belong because AWS Config evaluates resource compliance against desired configurations, not runtime latency. Option E does not belong because VPC Flow Logs capture IP-level metadata (accepted/rejected traffic, bytes, ports) and cannot show application-layer latency or packet loss/throttling details.

Answer

Check AWS Config rules for any non-compliant resources.

Answer

Review VPC Flow Logs to check for packet loss or throttling.

Question 4

A company is planning to run SAP NetWeaver on AWS and needs to ensure that the system is highly available. Which TWO AWS services should be combined to achieve HA for the SAP central services (ASCS/SCS) and the database? (Choose TWO.)

Accepted Answer

Elastic Load Balancing (ELB) to distribute traffic across multiple application server instances.. Option A is correct because Elastic Load Balancing distributes incoming SAP application traffic across multiple application server instances, so if one app server fails the load balancer routes requests to healthy instances, which is a core component of an HA architecture for SAP NetWeaver on AWS. Option C is correct because Amazon EC2 Auto Recovery automatically recovers an impaired instance (for example, one hosting ASCS/SCS) by moving it to healthy hardware and restarting it, preserving the instance ID, IP, and attached EBS volumes, which helps maintain availability of the central services. The other options do not belong: CloudFront (B) is a CDN for caching static content and does not provide HA for SAP central services or databases; S3 (D) is object storage for configuration files and is not an HA mechanism for running ASCS/SCS or the database; and Route 53 health checks with failover routing (E) can redirect DNS traffic to a standby endpoint but by itself does not provide the instance-level recovery or load distribution needed for the SAP central services and database HA scenario described.

Answer

Amazon CloudFront to cache static content.

Answer

Amazon S3 to store the SAP system configuration files.

Answer

Amazon Route 53 health checks with failover routing.

Question 5

An SAP administrator created the IAM policy shown in the exhibit. When trying to terminate an EC2 instance with ID i-abc123 in us-west-2, the action fails. What is the reason?

Accepted Answer

The ec2:TerminateInstances action is restricted to instances in us-east-1 only.. The policy includes a condition that restricts the ec2:TerminateInstances action to the us-east-1 region using the ec2:Region condition key. Since the instance i-abc123 is in us-west-2, the condition is not satisfied, causing the action to fail. AWS IAM policies evaluate conditions before allowing an action, and if the condition is not met, the action is denied.

Answer

There is an implicit Deny for all actions not explicitly allowed.

Answer

The policy is missing a condition key to allow termination in us-west-2.

Answer

The ec2:StartInstances and ec2:StopInstances actions are not granted for the specific instance.

Question 6

An SAP HANA administrator sees the error log entry shown in the exhibit. The error occurs when a scheduled job tries to insert data into the BKPF table. What is the MOST likely cause?

Accepted Answer

The credentials used by the scheduled job are incorrect.. The error log entry indicates that the scheduled job is failing during an INSERT operation on the BKPF table. In SAP HANA, when a scheduled job fails with an authentication or authorization error, the most common cause is incorrect credentials being used by the job's connection to the database. This is because the job's runtime context does not have the correct user or password to establish a valid session, leading to a failure before any SQL operation is attempted.

Answer

The user does not have INSERT privilege on the BKPF table.

Answer

The SQL statement has a syntax error.

Answer

The table BKPF is full and cannot accept new rows.

Question 7

A company is running an SAP HANA database on an Amazon EC2 instance. The storage is configured with multiple EBS volumes striped using LVM. The company wants to ensure the database performance is consistent and can detect potential bottlenecks. Which AWS service should be used to monitor the EBS volume metrics such as Average Queue Length and Throughput?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch is the correct service because it provides detailed, granular monitoring of EBS volume metrics such as Average Queue Length (AverageQueueLength) and Throughput (VolumeReadBytes/VolumeWriteBytes). These metrics are collected at 1-minute intervals by default for EBS volumes attached to Nitro-based EC2 instances, enabling you to detect performance bottlenecks like high queue depths or throughput saturation. CloudWatch also allows you to set alarms and create dashboards for proactive monitoring of SAP HANA database storage performance.

AWS CloudTrail

Question 8

A company is migrating its SAP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS/ERS) instance. The solution must support automatic failover in case of an instance failure. Which AWS service should be used to manage the floating IP address required for the SAP high availability setup?

Accepted Answer

Amazon Route 53. Amazon Route 53 can be configured with health checks and DNS failover to manage the floating IP address required for SAP Central Services (ASCS/ERS) high availability. When the primary ASCS instance fails, Route 53 automatically updates DNS resolution to point to the secondary instance's IP address, enabling automatic failover without requiring a static floating IP.

Answer

Elastic IP address

Answer

Amazon CloudFront

Answer

AWS Global Accelerator

Question 9

A company runs SAP on AWS and uses a Multi-AZ RDS for SAP HANA as the database. The database instance is m5.8xlarge with 1000 GB of gp2 storage. The application team reports that write latency spikes during peak hours. The average write throughput is 200 MB/s. Which change would most effectively reduce write latency?

Accepted Answer

Change the volume type to Provisioned IOPS (io1 or io2). The scenario involves a Multi-AZ RDS instance using gp2 storage. gp2 volumes in RDS have a burst-bucket model; for a 1000 GB volume, baseline performance is 3000 IOPS, which cannot sustain the required 200 MB/s write throughput (approximately 12,800 IOPS with 16 KB block size). Sustained high throughput leads to burst credit exhaustion, causing latency spikes. Option A (increasing volume size) improves baseline IOPS but still insufficient; Option B (EBS Auto Scaling) is not applicable to RDS; Option C (st1) is throughput-optimized but not suitable for latency-sensitive databases. Provisioned IOPS (io1/io2) provides guaranteed, consistent performance, eliminating latency spikes for SAP HANA.

Answer

Increase the volume size to 2000 GB

Answer

Enable EBS Auto Scaling on the volume

Answer

Change the volume type to Throughput Optimized (st1)

Question 10

A company is implementing SAP HANA on AWS and needs to ensure that the storage configuration meets the required IOPS and throughput. The SAP HANA system uses a scale-out architecture with multiple worker nodes. Which type of Amazon EBS volume is recommended for the /hana/data and /hana/log volumes in a production environment?

Accepted Answer

Provisioned IOPS SSD (io1 or io2). For SAP HANA production workloads on AWS, the /hana/data and /hana/log volumes require consistent, high IOPS and low latency. Provisioned IOPS SSD (io1 or io2) volumes are recommended because they allow you to specify a guaranteed IOPS rate independent of volume size, meeting SAP's strict performance requirements for scale-out architectures. General Purpose SSD volumes (gp2/gp3) cannot provide the sustained, predictable IOPS needed for critical SAP HANA operations, especially under burst conditions.

Answer

Throughput Optimized HDD (st1)

Answer

General Purpose SSD (gp2 or gp3)

Answer

Cold HDD (sc1)

Question 11

A company is running SAP on AWS and needs to back up the SAP HANA database daily. The database is 1 TB in size and the backup must be completed within 2 hours. The backup will be stored in Amazon S3. Which approach provides the fastest backup time while minimizing cost?

Accepted Answer

Use the SAP HANA Backint agent to stream backups directly to S3. The SAP HANA Backint agent is the native, certified integration for SAP HANA backups to Amazon S3. It streams backup data directly to S3 via the Backint API, eliminating intermediate storage and minimizing data transfer overhead. This approach achieves the fastest backup time because it avoids the latency of writing to instance store, EBS, or EFS before reaching S3, and it incurs only S3 storage costs without additional compute or storage fees.

Answer

Copy the backup files to an EC2 instance store, then upload to S3

Answer

Take EBS snapshots of the volume

Answer

Mount an Amazon EFS file system and write backups to it

Question 12

A company is deploying SAP NetWeaver on AWS and needs to configure the SAP application server instances for high availability. Which AWS feature is used to distribute traffic across multiple application server instances in different Availability Zones?

Accepted Answer

Application Load Balancer. The Application Load Balancer (ALB) is the correct AWS service for distributing traffic across multiple SAP application server instances in different Availability Zones. ALB operates at Layer 7, supports health checks, and can route HTTP/HTTPS traffic to target groups spanning multiple AZs, which is essential for SAP NetWeaver's stateless application layer high availability.

Answer

Auto Scaling group

Answer

Amazon Route 53 weighted routing

Answer

NAT Gateway

Question 13

A company is running SAP HANA on a bare metal EC2 instance. The system experiences a hardware failure that causes an instance stop. The company needs to recover the instance quickly. What should the company do to minimize recovery time?

Accepted Answer

Configure an Amazon CloudWatch alarm to automatically recover the instance. Amazon CloudWatch can automatically recover an impaired EC2 instance by restarting it on new underlying hardware, preserving the instance ID, private IP, Elastic IP, and EBS attachments. This minimizes recovery time by eliminating manual intervention and leveraging AWS's automated recovery mechanism, which is specifically designed for hardware failures on bare metal instances like those running SAP HANA.

Answer

Use AWS CloudFormation to recreate the instance

Answer

Manually start the instance from the EC2 console

Answer

Restore the instance from the latest EBS snapshot

Question 14

Which TWO of the following are required components for an SAP HANA scale-out deployment on AWS that uses shared storage for /hana/shared? (Choose two.)

Accepted Answer

Amazon EFS file system. For an SAP HANA scale-out deployment on AWS that uses shared storage for /hana/shared, the shared file system must be a network-accessible, POSIX-compliant, multi-attach storage service. Option A (Amazon EFS file system) is correct because EFS provides a fully managed NFSv4.1 file system that can be mounted concurrently by multiple EC2 instances across Availability Zones, which is exactly what /hana/shared requires in a scale-out topology. Option D (Amazon FSx for NetApp ONTAP) is also correct because it delivers a shared, POSIX-compliant NFS/SMB file system with multi-attach capability and is a supported AWS shared-storage option for SAP HANA /hana/shared. Option B (EC2 instance store) is not correct because it is ephemeral, physically attached to a single instance, and cannot be shared across the scale-out nodes. Option C (Amazon S3 bucket) is not correct because S3 is object storage, not a POSIX file system, and cannot be mounted directly as /hana/shared. Option E (Amazon EBS volume) is not correct because EBS volumes are block devices typically attached to a single EC2 instance (except limited Multi-Attach io1/io2 scenarios) and do not provide the shared NFS file system required for /hana/shared.

Answer

EC2 instance store

Answer

Amazon S3 bucket

Answer

Amazon EBS volume

Question 15

Which THREE of the following are valid methods to automate the installation of SAP HANA on AWS? (Choose three.)

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP (B) is correct because it is a purpose-built AWS service that guides you through deploying SAP HANA and SAP NetWeaver workloads on AWS, automatically provisioning the required EC2 instances, EBS volumes, and security groups based on SAP-certified best practices. SAP Cloud Appliance Library (C) is correct because it provides pre-configured, SAP-certified appliance templates (including SAP HANA) that can be deployed directly into an AWS account, automating the installation and configuration of the SAP software stack. AWS CloudFormation with a custom template (E) is correct because CloudFormation is an infrastructure-as-code service that can automate the provisioning of AWS resources and, via UserData scripts or AWS Systems Manager documents embedded in the template, execute the SAP HANA installation steps. AWS Systems Manager Automation (A) is not among the marked answers because, while it can run automation documents to configure instances, it is not a recognized end-to-end method for automating SAP HANA installation on AWS in this context. AWS OpsWorks (D) is not marked because it is a configuration-management service (Chef/Puppet) that has been deprecated for new customers and is not a standard method for automating SAP HANA installation on AWS.

Answer

AWS Systems Manager Automation

Answer

AWS OpsWorks
