PAS-C01 Practice Test 35 — 15 Questions

Question 1

A company is designing a disaster recovery (DR) strategy for SAP on AWS. The primary region is us-east-1 and the DR region is us-west-2. The SAP HANA database is 2 TB. The recovery point objective (RPO) is 15 minutes and the recovery time objective (RTO) is 4 hours. Which solution meets these requirements most cost-effectively?

Accepted Answer

HANA System Replication in asynchronous mode. HANA system replication in sync mode over a reasonable distance (us-east-1 to us-west-2) can achieve sub-15 minute RPO. However, latency may cause performance impact. Async mode is typically used for long distance. Option A (HANA System Replication in async mode) meets RPO and RTO cost-effectively. Option B (sync mode) may not be feasible due to latency. Option C (EBS snapshots) has higher RPO. Option D (RTO too high).

Answer

HANA System Replication in synchronous mode

Answer

Log shipping to an S3 bucket in DR region

Answer

EBS snapshot replication to DR region using AWS Backup

Question 2

An SAP system is running on an EC2 instance with a single Amazon EBS volume for data and log files. The database administrator wants to increase the IOPS performance without changing the instance type. Which action should be taken?

Accepted Answer

Modify the EBS volume to provisioned IOPS (io1/io2).. Option D is correct because you can increase the IOPS of an existing EBS volume by modifying it to a higher IOPS value. Option A is wrong because changing instance type may not be necessary. Option B is wrong because EBS optimization is enabled by default for certain instances. Option C is wrong because you cannot change EBS volume type directly to instance store; instance store is ephemeral.

Answer

Enable EBS optimization on the EC2 instance.

Answer

Change the EC2 instance type to a larger size.

Answer

Migrate the data to an instance store volume.

Question 3

A company is planning a migration of their SAP ERP system to AWS. They want to use SAP HANA as the database. The current on-premises database size is 2 TB. The migration must have minimal downtime. Which combination of AWS services and methods should be used to achieve a near-zero downtime migration?

Accepted Answer

Use AWS DMS with a SAP HANA source and target, configuring ongoing replication to minimize downtime. Option D is correct because AWS DMS with HANA as target supports minimal downtime using ongoing replication. Option A is incorrect because HSR requires a compatible HANA version setup. Option B is incorrect because DMS cannot replicate from HANA to HANA directly without a source HANA. Option C is incorrect because AWS Backup cannot replicate data in near-real-time.

Answer

Use AWS Database Migration Service (DMS) with an SAP HANA source and S3 as target

Answer

Use SAP HANA System Replication (HSR) to replicate data to an EC2 instance in AWS

Answer

Use AWS Backup to perform a continuous backup of the on-premises HANA database and restore to AWS

Question 4

A company is running a production SAP HANA database on an AWS EC2 instance with a single EBS gp3 volume. The database frequently experiences high write latency during peak hours. Which design change would MOST effectively reduce write latency?

Accepted Answer

Replace the single gp3 volume with multiple io2 Block Express volumes configured in a RAID 0 stripe.. Option C is correct because using multiple EBS io2 Block Express volumes with a RAID 0 stripe distributes the I/O and provides higher throughput and lower latency than a single gp3 volume. Option A (Increase gp3 volume size) might improve throughput but not latency as much as io2. Option B (Switch to a larger EC2 instance) does not directly address disk latency. Option D (Move to Amazon RDS) is not applicable for SAP HANA.

Answer

Increase the size of the existing gp3 volume to maximize its baseline throughput.

Answer

Migrate the database to a larger EC2 instance type with higher network bandwidth.

Answer

Move the SAP HANA database to Amazon RDS for SAP HANA.

Question 5

An SAP administrator is configuring high availability for SAP HANA using HANA system replication (HSR) across multiple Availability Zones. The administrator must ensure that the replication traffic is encrypted and uses the most efficient network path. Which TWO configurations meet these requirements? (Choose TWO.)

Accepted Answer

Enable SAP HANA system replication with TLS/SSL encryption.. Options A and C are correct. Option A (VPC peering) allows direct connectivity between AZs within the same region. Option C (TLS/SSL encryption) ensures encryption of replication traffic. Option B (VPN) adds overhead and is not needed. Option D (Direct Connect) is for on-premises connectivity. Option E (S3) is not involved.

Answer

Store replication data in Amazon S3 and have the secondary instance pull it.

Answer

Use AWS Direct Connect to connect the Availability Zones.

Answer

Configure a VPN connection between the Availability Zones.

Question 6

An SAP system on AWS needs to store sensitive configuration files securely and automatically rotate the encryption keys. Which AWS service should be used?

Accepted Answer

AWS Systems Manager Parameter Store with AWS KMS.. Option A is correct because AWS Systems Manager Parameter Store securely stores configuration and can integrate with KMS for key rotation. Option B is wrong because S3 does not automatically rotate keys. Option C is wrong because Secrets Manager is for secrets, not configuration with automatic rotation of keys. Option D is wrong because KMS manages keys, not configuration storage.

Answer

Amazon S3 with server-side encryption.

Answer

AWS Key Management Service (KMS) alone.

Answer

AWS Secrets Manager.

Question 7

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. Option A is correct because CloudWatch can monitor EC2 metrics and trigger alarms based on CPU utilization. Option B is wrong because CloudTrail is for auditing API calls, not monitoring. Option C is wrong because Config is for resource configuration tracking. Option D is wrong because Trusted Advisor provides best practice checks, not monitoring.

Answer

AWS CloudTrail

Answer

AWS Trusted Advisor

Answer

AWS Config

Question 8

An SAP Basis administrator needs to migrate an on-premises SAP ERP system running on Oracle to AWS. The system has a 2 TB database and requires minimal downtime (less than 1 hour). The current on-premises network bandwidth to AWS is 1 Gbps. Which migration strategy is MOST appropriate?

Accepted Answer

Use AWS Database Migration Service (DMS) with ongoing replication from Oracle to Amazon RDS for Oracle, then perform a final cutover.. Option B is correct because AWS DMS can perform ongoing replication to keep the target in sync, then a short cutover achieves <1 hour downtime. Option A (AWS MGN) is for server-level replication, not optimized for database migration with minimal downtime. Option C (SAP HSR) is specific to SAP HANA. Option D (SAP DMO) is a methodology but typically used for system copy or upgrade, not real-time replication.

Answer

Export the database using SAP HANA System Replication (HSR) to an Amazon EC2 instance with HANA.

Answer

Perform a manual export/import using Oracle Data Pump and transfer the dump file via AWS Direct Connect.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire server to AWS, then cut over.

Question 9

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.. Options A and B are correct. Elastic Load Balancing distributes traffic to multiple application servers. EC2 Auto Recovery automatically recovers an instance from hardware failure. Option C (S3) is for storage. Option D (CloudFront) is a CDN. Option E (Route 53) is for DNS, not HA for services.

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 10

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. An Application Load Balancer (ALB) can distribute HTTP/HTTPS traffic across multiple targets in different AZs. Option D is correct. Route 53 is a DNS service, not a load balancer. NAT Gateway is for outbound traffic. Auto Scaling groups manage instance count, not traffic distribution.

Answer

Auto Scaling group

Answer

Amazon Route 53 weighted routing

Answer

NAT Gateway

Question 11

An SAP system running on AWS is experiencing performance issues. The operations team suspects that the Amazon EBS volumes attached to the SAP application server are not providing sufficient IOPS. Which AWS service should be used to monitor the IOPS performance of the EBS volumes?

Accepted Answer

Amazon CloudWatch. Option D is correct because Amazon CloudWatch provides metrics for EBS volumes including IOPS. Option A is wrong because AWS CloudTrail logs API calls, not performance metrics. Option B is wrong because Amazon Inspector is for security assessment. Option C is wrong because AWS Config tracks resource configuration changes.

Answer

AWS Config

Answer

AWS CloudTrail

Answer

Amazon Inspector

Question 12

A company operates an SAP system on AWS with a shared SAP HANA database across multiple SAP applications. The database size is 5 TB. The operations team wants to implement a disaster recovery strategy with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. Which solution meets these requirements with the least operational overhead?

Accepted Answer

Configure SAP HANA System Replication (HSR) to a secondary instance in another AWS Region. Option C is correct because HANA System Replication with a standby in another Region provides near real-time replication and fast failover. Option A is incorrect because DMS cannot replicate HANA to S3 for DR. Option B is incorrect because backup to S3 has higher RPO. Option D is incorrect because CloudEndure is not optimized for HANA replication.

Answer

Use AWS DMS to replicate data to an S3 bucket in a different Region

Answer

Use SAP HANA backup to S3 and restore in another Region

Answer

Use AWS CloudEndure Disaster Recovery to replicate the entire server

Question 13

A company is planning to migrate its SAP landscape to AWS. The SAP systems include a production system, a QA system, and a development system. All systems use the same SAP S/4HANA version. Which strategy is MOST cost-effective for the DR (disaster recovery) setup?

Accepted Answer

Use cross-Region replication with AWS reserved instances for the DR systems.. Option D is correct because cross-Region replication for DR using a single reserved instance for each system is cost-effective compared to running full active instances. Option A (Active-active) would incur double cost. Option B (Pilot light) would require starting instances on failure, impacting RTO. Option C (Warm standby) is more expensive than cross-Region replication with reserved instances.

Answer

Set up warm standby in a second Region with a standby application server and database.

Answer

Use a pilot light strategy with AWS DMS ongoing replication.

Answer

Deploy active-active SAP systems in two AWS Regions with Elastic Load Balancing.

Question 14

An SAP application running on AWS is experiencing high latency for database write operations. The system uses SAP ASE on Amazon EC2 with gp2 EBS volumes. Which change is most likely to improve write performance?

Accepted Answer

Migrate to io1/io2 EBS volumes with provisioned IOPS.. Option B is correct because io1/io2 volumes provide consistent IOPS performance suitable for database workloads. Option A is wrong because gp3 may still not guarantee low latency writes. Option C is wrong because instance store is ephemeral and data is lost on stop/termination. Option D is wrong because S3 is object storage, not block storage for database.

Answer

Move database write logs to Amazon S3 for better throughput.

Answer

Migrate to gp3 EBS volumes with higher baseline performance.

Answer

Use instance store volumes for database data files.

Question 15

Which THREE services can be used together to implement a disaster recovery solution for SAP S/4HANA on AWS with a recovery time objective (RTO) of less than 1 hour and a recovery point objective (RPO) of less than 15 minutes?

Accepted Answer

SAP HANA System Replication across regions.. Option A is correct: HANA System Replication provides low RPO. Option C is correct: S3 can store backups for log replay. Option D is correct: CloudEndure Disaster Recovery can replicate entire servers. Option B is wrong because DMS doesn't support HANA. Option E is wrong because Glacier has retrieval times > 1 hour.

Answer

AWS Database Migration Service (DMS) for ongoing replication.

Answer

Amazon S3 Glacier for long-term backups.
