PAS-C01 Practice Test 3 — 10 Questions

Question 1

A company runs its SAP ERP system on AWS with an SAP HANA database on an EC2 instance. The database is configured with multiple EBS io1 volumes striped in a RAID 0. Recently, the company implemented a new backup process using AWS Backup with the Backint agent. However, during the backup window, the database performance degrades significantly, causing application timeouts. The database administrator checks CloudWatch metrics and sees that the EBS write latency spikes to over 50 ms during backups. The backup target is an S3 bucket in the same region. The EC2 instance type is r5.4xlarge with EBS-optimized enabled. What is the MOST likely cause of the performance degradation?

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

Accepted Answer

The Backint agent is consuming CPU and I/O resources, causing contention.. The Backint agent runs on the same EC2 instance as SAP HANA, consuming CPU and I/O resources during backup, causing contention and performance degradation. Option B is unlikely because with RAID 0 the aggregate IOPS is higher than the provisioned per volume limit. Option C is incorrect because the S3 bucket is in the same region as stated. Option D is incorrect because the r5.4xlarge instance supports EBS optimization and is suitable for Backint.

Answer

The EBS volumes have reached the provisioned IOPS limit of 20,000 IOPS.

Answer

The S3 bucket is in a different region, causing network latency.

Answer

The EC2 instance type does not match the requirements for Backint.

Question 2

A company is migrating a large-scale SAP environment to AWS. Which THREE AWS services can be used to optimize storage costs for SAP workloads? (Choose three.)

Accepted Answer

Amazon S3 Lifecycle policies to transition data. Amazon S3 Lifecycle policies (Option B) allow you to automatically transition SAP backup and archival data from S3 Standard to lower-cost storage classes like S3 Standard-IA or S3 Glacier, reducing storage costs without manual intervention. This is critical for SAP workloads where large volumes of backup data accumulate over time and do not require immediate access.

Answer

AWS Storage Gateway for on-premises caching

Answer

Amazon S3 Standard for all data

Question 3

A company is migrating a legacy application to AWS. The application currently uses Oracle Database and the company wants to migrate to Amazon Aurora PostgreSQL with minimal downtime. Which TWO steps should be taken to achieve this? (Choose TWO)

Accepted Answer

Use the AWS Schema Conversion Tool (SCT) to convert the Oracle schema to PostgreSQL.. The AWS Schema Conversion Tool (SCT) can automatically convert Oracle database schemas (including stored procedures, views, and data types) to a PostgreSQL-compatible format, which is essential when migrating to Amazon Aurora PostgreSQL. Option D is correct because AWS DMS with ongoing replication (change data capture) allows you to keep the source Oracle database and target Aurora PostgreSQL synchronized with minimal downtime, enabling a near-zero-downtime migration by capturing and applying incremental changes.

Answer

Rehost the Oracle database on an Amazon EC2 instance to minimize changes.

Answer

Configure Amazon Aurora PostgreSQL with Multi-AZ for high availability.

Answer

Export Oracle database as dump files and import into Aurora PostgreSQL using native tools.

Question 4

A company is designing a highly available SAP NetWeaver system on AWS. The architecture includes two EC2 instances running the ABAP application server in an Auto Scaling group. Which THREE components are required to maintain session persistence and distribute traffic? (Choose THREE.)

Accepted Answer

Health checks on the target group to detect unhealthy instances. Health checks on the target group are required to detect unhealthy EC2 instances running the ABAP application server. When an instance fails a health check, the load balancer automatically stops routing traffic to it, ensuring that only healthy instances serve requests. This is critical for maintaining high availability in an SAP NetWeaver environment, as it prevents session failures caused by underlying instance issues.

Answer

A shared file system (e.g., Amazon EFS) for /sapmnt

Answer

A Multi-AZ deployment for the SAP application servers

Question 5

An architect is designing a disaster recovery plan for an SAP system using SAP HANA. The primary site is in us-east-1 and the DR site is in us-west-2. The RPO is 15 minutes and RTO is 1 hour. Which TWO AWS services or features should the architect use to meet these requirements? (Choose TWO.)

Accepted Answer

AWS Elastic Disaster Recovery (AWS DRS). SAP HANA System Replication (option D) is the native SAP mechanism for replicating HANA databases synchronously or asynchronously, supporting an RPO of 15 minutes with asynchronous replication. AWS Elastic Disaster Recovery (option B) provides continuous block-level replication for the entire SAP system (including OS and application volumes) and enables automated failover within the 1-hour RTO. Together, they ensure both database consistency and full infrastructure recovery.

Answer

AWS Transit Gateway with VPC peering

Answer

Amazon S3 Cross-Region Replication

Answer

AWS CloudEndure Disaster Recovery

Question 6

A company is designing a disaster recovery (DR) strategy for SAP S/4HANA on AWS. The primary site is in us-east-1 and the DR site is in us-west-2. The SAP HANA database is 2 TB and requires Recovery Point Objective (RPO) of 15 minutes and Recovery Time Objective (RTO) of 4 hours. Which solution meets these requirements?

Accepted Answer

Configure SAP HANA System Replication (HSR) to an EC2 instance in us-west-2 with log replication in sync mode.. SAP HANA System Replication (HSR) with synchronous log replication meets the RPO of 15 minutes and RTO of 4 hours because it continuously replicates transaction logs to the DR site in us-west-2, ensuring near-zero data loss. In sync mode, the primary waits for the secondary to acknowledge log writes, which keeps the DR database consistent and ready for takeover within minutes, well under the 4-hour RTO. This is the only option that provides continuous, database-level replication with the required recovery objectives.

Answer

Use AWS S3 Cross-Region Replication to copy database backups every 15 minutes.

Answer

Take EBS snapshots of the HANA data volume every hour and copy them to us-west-2.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate changes to a HANA instance in us-west-2.

Question 7

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that is not supported by AWS Database Migration Service (DMS). The company needs to minimize downtime and automate the migration as much as possible. Which approach should be used?

Accepted Answer

Use AWS Application Migration Service (MGN) to replicate the entire server, including the database, to AWS.. AWS Application Migration Service (MGN) can replicate entire servers, including the operating system, applications, and the proprietary database, to AWS without requiring database-specific support. This minimizes downtime by using continuous block-level replication and automates the migration by converting the source server into a native AWS instance. Since AWS DMS does not support the proprietary database, MGN provides a viable path for migrating the entire workload as a whole.

Answer

Use AWS Database Migration Service (DMS) with a custom endpoint.

Answer

Export the database as a flat file, upload to Amazon S3, and import into Amazon RDS.

Answer

Use AWS Snowball to transfer database backups, then restore in Amazon RDS.

Question 8

An SAP system on AWS is running on an r5.16xlarge instance. The system is experiencing network throughput bottlenecks. Which step should be taken to improve network performance?

Accepted Answer

Enable Enhanced Networking and install the ENA driver. Enabling Enhanced Networking and installing the Elastic Network Adapter (ENA) driver is the standard method to achieve higher packet-per-second (PPS) performance, lower latency, and increased network bandwidth on supported instance types like r5.16xlarge. Without the ENA driver, the instance uses the older Xen network driver, which cannot utilize the full 25 Gbps network bandwidth available to r5 instances, leading to throughput bottlenecks.

Answer

Move the instance to a placement group

Answer

Attach an Elastic Fabric Adapter

Answer

Change the instance type to c5.18xlarge

Question 9

An SAP administrator needs to back up an SAP HANA database running on an Amazon EC2 instance. The requirement is to perform daily backups to Amazon S3 with minimal cost and impact on database performance. Which backup strategy should be used?

Accepted Answer

Use SAP HANA Backint integration to back up to S3. SAP HANA Backint integration allows direct, streaming backups from the HANA database to Amazon S3, which minimizes performance impact by offloading backup processing to the Backint agent and avoids intermediate storage. This approach is cost-effective as it uses S3's low-cost storage and eliminates the need for additional infrastructure, meeting the requirement for daily backups with minimal cost and database performance impact.

Answer

Use AWS Backup with the SAP HANA plugin

Answer

Create EBS snapshots of the database volumes

Answer

Configure S3 Lifecycle policies to move logs

Question 10

A company is deploying SAP NetWeaver on AWS and needs to ensure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which AWS services can be used to implement a failover cluster for ASCS and ERS? (Select THREE.)

Accepted Answer

Elastic Load Balancing. Elastic Load Balancing (ELB) is correct because it can be used in conjunction with a Network Load Balancer (NLB) to provide a stable endpoint for SAP ASCS and ERS failover. The NLB supports static IP addresses and can be configured with health checks that monitor the SAP service, automatically routing traffic to the healthy node in the cluster. This eliminates the need for a traditional floating IP and integrates with AWS-native failover mechanisms.

Answer

AWS CloudTrail

Answer

AWS Config
