PAS-C01 Design of SAP Workloads on AWS Practice Test 28 — 15 Questions

Question 1

A company is migrating an SAP S/4HANA system to AWS. The system requires high availability across two Availability Zones. Which AWS service should be used to attach a block-level storage volume that can be concurrently accessed by two EC2 instances in active/passive mode?

Accepted Answer

Use Amazon FSx for NetApp ONTAP to provide a shared block storage volume accessible from both AZs.. Option B is correct because Amazon EBS Multi-Attach allows a single EBS volume to be attached to multiple EC2 instances in the same Availability Zone, but for active/passive across AZs, shared EBS is not supported; the correct service is Amazon EFS, but EFS is file-level. For block-level concurrent access across AZs, Amazon FSx for NetApp ONTAP provides shared block storage. Option A is wrong because EBS Multi-Attach only works within a single AZ. Option C is wrong because FSx for Windows File Server is file-level. Option D is wrong because S3 is object storage.

Answer

Use Amazon FSx for Windows File Server with a multi-AZ file system.

Answer

Use Amazon S3 as a shared block storage device.

Answer

Use Amazon EBS Multi-Attach to attach a single EBS volume to both EC2 instances across AZs.

Question 2

An SAP Basis administrator is troubleshooting a performance issue on an SAP HANA database running on an EC2 instance. The administrator notices that the 'hdbcons' command shows high 'wait time' for 'disk I/O' operations. The instance is an r5.4xlarge with 500 GB of gp2 EBS volumes for /hana/data and /hana/log. Which of the following is the MOST effective action to improve disk I/O performance?

Accepted Answer

Change the EBS volume type from gp2 to gp3 with higher IOPS and throughput.. Option C is correct because converting gp2 volumes to gp3 provides higher baseline IOPS and throughput without additional cost for provisioned IOPS. Option A is wrong because disabling HANA's delta merge increases fragmentation, worsening performance. Option B is wrong because increasing EBS snapshot frequency does not affect I/O performance. Option D is wrong because using a larger instance type addresses compute, not disk I/O.

Answer

Increase the frequency of EBS snapshots to offload I/O.

Answer

Upgrade to a larger EC2 instance type with more CPU and memory.

Answer

Disable the HANA delta merge operation to reduce I/O load.

Question 3

A company runs SAP ERP on AWS using an Oracle database. To meet disaster recovery requirements, they need to replicate the database to a second AWS Region with low RPO. Which AWS service should be used for continuous, asynchronous replication of the Oracle database?

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication from the source Oracle database to a target Oracle database in the DR Region.. Option A is correct because AWS DMS with ongoing replication can continuously replicate Oracle data to another Region with low latency. Option B is wrong because S3 Cross-Region Replication is for objects, not databases. Option C is wrong because RDS for Oracle Read Replicas only work within the same Region. Option D is wrong because EC2 AMI copy is not continuous.

Answer

Copy the EC2 instance with the Oracle database as an AMI to the DR Region.

Answer

Amazon S3 Cross-Region Replication (CRR) to replicate database backups.

Answer

Amazon RDS for Oracle Read Replicas in the DR Region.

Question 4

Refer to the exhibit. An SAP administrator created this IAM policy for an SAP application user that performs database backups to Amazon S3. The user reports that backup jobs fail with an access denied error. What is the most likely cause?

Accepted Answer

The policy is missing s3:ListBucket permission on the bucket.. Option B is correct because the Deny statement denies s3:DeleteObject when SecureTransport is false, but the user may be using HTTPS (SecureTransport true), which is fine. However, the error is likely due to missing s3:ListBucket permission to list objects in the bucket. Option A is wrong because the policy allows PutObject. Option C is wrong because the Deny condition only applies when SecureTransport is false. Option D is wrong because the Allow statement exists.

Answer

The policy has a syntax error and is invalid.

Answer

The policy does not allow s3:PutObject for the bucket.

Answer

The Deny statement blocks all DeleteObject requests.

Question 5

A company runs SAP on AWS with an SAP HANA database on a single EC2 instance. They want to implement a disaster recovery solution with a recovery time objective (RTO) of 15 minutes and a recovery point objective (RPO) of 1 hour. The DR site is in a different AWS Region. Which approach meets these requirements?

Accepted Answer

Configure SAP HANA System Replication to a secondary instance in the DR Region and use automated EBS snapshots for cross-Region replication.. Option D is correct because SAP HANA System Replication with HANA Backup/Restore using cross-Region EBS snapshots can achieve RPO of 1 hour and RTO of 15 minutes if automated. Option A is wrong because copying AMIs every hour may not achieve RPO consistently and RTO may be longer. Option B is wrong because S3 versioning does not provide database-level replication. Option C is wrong because manual restore from backup cannot achieve 15-minute RTO.

Answer

Set up an automated process to copy the EC2 instance AMI to the DR Region every hour.

Answer

Use Amazon S3 Cross-Region Replication to replicate the HANA data directory to the DR Region.

Answer

Perform periodic HANA database backups to S3 and restore in the DR Region when needed.

Question 6

Which AWS service should be used to capture and analyze operating system-level metrics from an EC2 instance running SAP, such as memory utilization and disk I/O, and to set alarms based on thresholds?

Accepted Answer

Amazon CloudWatch with the CloudWatch Agent. Option C is correct because Amazon CloudWatch with the CloudWatch Agent can collect OS-level metrics and trigger alarms. Option A is wrong because AWS Config is for resource compliance. Option B is wrong because AWS Trusted Advisor provides best practice checks, not metrics. Option D is wrong because Amazon Inspector is for security assessments.

Answer

AWS Config

Answer

AWS Trusted Advisor

Answer

Amazon Inspector

Question 7

An SAP system on AWS is experiencing intermittent connectivity issues between the SAP application servers and the HANA database server. The network team confirms that the VPC network ACLs and security groups allow all required traffic. However, the issue occurs only during peak load. What is the most likely cause?

Accepted Answer

The EBS-optimized instance is not providing enough bandwidth for the database workload.. Option B is correct because EBS-optimized instances provide dedicated bandwidth for EBS traffic, and during peak load, the database workload may exceed the available EBS bandwidth, causing network I/O throttling and intermittent connectivity. This manifests as packet drops or timeouts between SAP application servers and the HANA database, even though security groups and ACLs are correctly configured.

Answer

The TCP segmentation offload (TSO) is causing packet drops.

Answer

The Elastic Network Adapter (ENA) is not enabled on the instance.

Answer

The instance is using IPv6 addresses for communication.

Question 8

A company plans to migrate its SAP ERP system from an on-premises environment to AWS. The system uses an Oracle database. Which AWS service provides the most cost-effective and high-performance storage for the Oracle data files?

Accepted Answer

Amazon EBS io2 Block Express volumes. Option B is correct because Amazon EBS io2 Block Express volumes offer high durability, high IOPS, and low latency suitable for Oracle databases. Option A is wrong because S3 is object storage. Option C is wrong because EFS is file storage. Option D is wrong because Instance Store is ephemeral.

Answer

EC2 Instance Store

Answer

Amazon EFS

Answer

Amazon S3

Question 9

An SAP administrator needs to set up a fault-tolerant architecture for SAP NetWeaver on AWS. The architecture must survive an entire Availability Zone failure. Which configuration is the most appropriate?

Accepted Answer

Use an Auto Scaling group to launch SAP application servers across multiple AZs behind an Application Load Balancer.. Option D is correct because an Auto Scaling group across multiple AZs with a load balancer provides fault tolerance for application servers. Option A is wrong because a single AZ does not survive AZ failure. Option B is wrong because EC2 without ASG lacks automatic recovery. Option C is wrong because a single EC2 instance with EBS snapshots is not highly available.

Answer

Deploy all SAP application servers in one Availability Zone and use Amazon EBS snapshots for backup.

Answer

Deploy SAP application servers across multiple AZs but without a load balancer.

Answer

Use a single large EC2 instance for all SAP components.

Question 10

A company runs SAP HANA on AWS. The system is experiencing high CPU utilization during peak hours. Which TWO actions should the administrator take to address this? (Choose two.)

Accepted Answer

Right-size the EC2 instance to a larger type with more vCPUs.. Option B and Option D are correct because right-sizing the instance (B) and implementing HANA workload management (D) directly address CPU utilization. Option A is wrong because disabling compression increases CPU for decompression. Option C is wrong because increasing EBS volume size does not affect CPU. Option E is wrong because reducing network throughput may impact performance.

Answer

Disable HANA columnar compression to reduce CPU overhead.

Answer

Increase the size of the /hana/data EBS volumes.

Answer

Reduce the network throughput of the EC2 instance.

Question 11

An SAP system on AWS uses an Oracle database. The administrator wants to automate the creation of daily backups and retain them for 30 days. Which THREE AWS services can be used together to achieve this? (Choose three.)

Accepted Answer

Amazon S3 lifecycle policies. Option A, Option C, and Option D are correct: AWS Backup (A) schedules backups, Amazon EBS snapshots (C) capture data, and Amazon S3 lifecycle policies (D) manage retention. Option B is wrong because AWS Lambda is not necessary for scheduling. Option E is wrong because CloudWatch is for monitoring.

Answer

AWS Lambda

Answer

Amazon CloudWatch Events

Question 12

A company is designing a disaster recovery solution for SAP HANA on AWS using HANA System Replication. The primary site is in us-east-1 and the DR site is in us-west-2. Which TWO components are required to enable replication across Regions? (Choose two.)

Accepted Answer

AWS Site-to-Site VPN or AWS Direct Connect between the two Regions. Option B and Option D are correct: A VPN or Direct Connect (B) provides network connectivity, and EBS snapshots (D) can be used to replicate data if synchronous replication is not feasible. Option A is wrong because S3 Transfer Acceleration is not needed. Option C is wrong because VPC peering does not work across Regions (use Transit Gateway or VPN). Option E is wrong because AWS Global Accelerator improves latency but is not required.

Answer

VPC peering between the two VPCs

Answer

AWS Global Accelerator

Answer

Amazon S3 Transfer Acceleration

Question 13

A company runs its SAP ERP system on AWS with an Oracle database on an EC2 instance. The system is used by thousands of users globally. Recently, the database has been experiencing slow query performance, especially during end-of-month processing. The administrator notices that the database instance is an r5.8xlarge with 32 vCPUs and 256 GB of memory, running on a single EBS io1 volume with 20,000 IOPS for the data files. The administrator has already optimized the SQL queries and increased the SGA size. However, performance remains poor. The Amazon CloudWatch metrics show that the EBS volume's Average Queue Length is consistently above 10 and the read latency spikes to over 100 ms during peak times. The CPU utilization is around 70%. Which action should the administrator take to resolve the I/O bottleneck?

Accepted Answer

Create multiple EBS io1 volumes and stripe them using RAID 0 at the OS level.. Option D is correct because distributing the Oracle data files across multiple EBS volumes with RAID 0 increases I/O parallelism and reduces queue length. Option A is wrong because increasing IOPS on a single volume may not help if the volume is already at its throughput limit. Option B is wrong because switching to gp3 may not provide enough IOPS for the workload. Option C is wrong because increasing instance size does not directly improve EBS performance; the bottleneck is at the storage layer.

Answer

Change the volume type to gp3 and increase the baseline IOPS.

Answer

Increase the IOPS of the existing io1 volume to 40,000.

Answer

Upgrade the EC2 instance to an r5.12xlarge with more network bandwidth.

Question 14

A company has deployed SAP S/4HANA on AWS using a single EC2 instance for the HANA database and multiple EC2 instances for the application servers. The system is in production and the company wants to implement high availability for the HANA database to minimize downtime during patching and failures. The HANA database is critical and must have an RTO of less than 5 minutes and an RPO of zero. The current setup uses a single EBS volume for /hana/data and another for /hana/log. The company has two Availability Zones available. Which solution meets the requirements?

Accepted Answer

Configure SAP HANA System Replication with automatic failover to a secondary HANA instance in another AZ.. Option B is correct because SAP HANA System Replication in active/passive mode with automatic failover provides near-zero RPO and fast RTO. Option A is wrong because manual failover takes longer than 5 minutes. Option C is wrong because EBS Multi-Attach does not support active/passive cross-AZ. Option D is wrong because a larger instance does not provide HA.

Answer

Attach the EBS volumes to two EC2 instances using EBS Multi-Attach.

Answer

Use AWS Backup to schedule snapshots every 5 minutes and restore in another AZ if needed.

Answer

Deploy the HANA database on a larger EC2 instance with higher availability SLA.

Question 15

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.. Option A is correct because using AWS Snowball Edge to transfer the database backup to AWS bypasses the network bottleneck. Option B is wrong because increasing instance size does not improve network speed. Option C is wrong because disabling encryption does not significantly speed up transfer. Option D is wrong because S3 Transfer Acceleration improves speed but may still be limited by 100 Mbps.

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.
