PAS-C01 Practice Test 41 — 15 Questions

Question 1

An SAP system administrator notices that the SAP Central Services (ASCS) instance on an EC2 instance has failed. The instance is still running, but the ASCS service is unresponsive. What is the MOST efficient way to restore the ASCS service without affecting the SAP application?

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

Accepted Answer

Restart the ASCS service using SAP MMC or sapcontrol.. The most efficient way to restore the ASCS service without affecting the SAP application is to restart the ASCS service using SAP MMC or sapcontrol (Option D). This action is quick and minimally disruptive, as it only restarts the service without impacting the underlying EC2 instance or requiring failover procedures. 
- Option A (fail over to secondary node) is less efficient because it requires a properly configured cluster environment and may take longer to orchestrate, and it may not be necessary if the primary node's service can be restarted.
- Option B (reboot the EC2 instance) is inefficient and disruptive because it restarts the entire instance, affecting all services and potentially causing downtime for the SAP application.
- Option C (restore from AMI backup) is the most time-consuming and resource-intensive approach, and is only appropriate if the instance or service is corrupt and cannot be recovered by restarting.

Answer

Manually fail over the ASCS to the secondary node in the cluster.

Answer

Reboot the EC2 instance hosting the ASCS.

Answer

Restore the ASCS instance from the most recent AMI backup.

Question 2

Refer to the exhibit. A company is migrating its data to Amazon S3. The security team has provided this IAM policy for the migration user. However, the migration fails with an Access Denied error when trying to upload files to the bucket. What is the most likely cause?

Accepted Answer

The bucket policy explicitly denies the s3:PutObject action for the IAM user.. The IAM policy allows s3:PutObject on the specified bucket. However, if the bucket has an explicit deny statement in its bucket policy that denies s3:PutObject for the user or any principal, that deny will override the IAM policy allow. Since the migration fails with Access Denied, the most likely cause is that the bucket policy explicitly denies the s3:PutObject action for the IAM user. Therefore, Option A is correct. Options B, C, and D are incorrect: Option B is wrong because the IAM policy does include s3:PutObject; Option C is wrong because there is no encryption requirement in the policy; Option D is wrong because default encryption does not cause Access Denied if the user lacks permission to use the key, but the policy does not mention KMS permissions.

Answer

The IAM policy does not include s3:PutObject permission.

Answer

The IAM policy does not include kms:Decrypt permission.

Answer

The bucket has default encryption enabled and the IAM user does not have permission to use the encryption key.

Question 3

A company is planning to migrate an SAP HANA database to AWS. Which THREE factors should the company consider when selecting an EC2 instance type for the SAP HANA database?

Accepted Answer

The instance must be EBS-optimized. For SAP HANA on AWS, EC2 instance types must be memory-optimized (e.g., r5, r6i, x1e) and listed in the SAP Certified Instance Types for SAP HANA. Additionally, instances must be EBS-optimized to provide dedicated bandwidth to EBS volumes. Burstable performance (option A) is not suitable for SAP HANA's consistent performance requirements. While the Nitro System (option C) is recommended, it is not a strict requirement.

Answer

The instance type must support burstable performance

Answer

The instance must be based on the AWS Nitro System

Question 4

A company is migrating its SAP landscape to AWS and wants to use SAP HSR (System Replication) for high availability. Which AWS feature is required to support SAP HSR?

Accepted Answer

Both instances in the same VPC with private IP connectivity. SAP HSR (System Replication) requires low-latency, reliable connectivity between the primary and secondary instances to synchronize data in real-time. Placing both instances in the same VPC enables them to communicate using private IP addresses, which are internal to the VPC and typically have lower latency and higher throughput compared to public IPs. This setup is essential for meeting the RPO and RTO requirements of SAP HSR. Options A (Elastic IP), B (Internet Gateway), and D (NAT Gateway) are not necessary for HSR and may introduce additional complexity or security risks.

Answer

Elastic IP addresses for each instance

Answer

Internet Gateway attached to the VPC

Answer

NAT Gateway for outbound traffic

Question 5

A company is migrating its SAP landscape to AWS and plans to use an SAP HANA multi-node scale-out configuration. Which THREE considerations are important for the network design?

Accepted Answer

Use a placement group to ensure nodes are in close proximity. For SAP HANA multi-node scale-out on AWS, three key network considerations are: using a placement group to ensure all nodes are in close physical proximity (option A), dedicating a separate network interface for HANA inter-node traffic to maximize performance (option B), and ensuring less than 1ms RTT latency between all nodes to meet HANA's strict requirements (option E). Option C (NAT Gateway) is incorrect because NAT Gateways provide outbound internet access, not inter-node connectivity. Option D (public IP addresses) is unnecessary and insecure for inter-node communication; private IPs with placement groups and low latency are sufficient.

Answer

Use a NAT Gateway for inter-node traffic

Answer

Use public IP addresses for inter-node communication

Question 6

A company is migrating a large SAP HANA system to AWS. The SAP system has strict latency requirements for storage and requires high IOPS. Which storage solution should be used for the SAP HANA data volume?

Accepted Answer

Amazon EBS io2 Block Express volumes. SAP HANA on AWS requires high-performance storage with high IOPS and sub-millisecond latency. Amazon EBS io2 Block Express volumes provide up to 256K IOPS and sub-millisecond latency, making them the appropriate choice for the SAP HANA data volume. Option A (Amazon S3) is object storage, not block storage, and is unsuitable for database volumes. Option C (Amazon EFS) is file storage, also not block storage. Option D (Amazon EBS gp3 volumes) is general purpose SSD but does not match the performance of io2 Block Express for HANA workloads.

Answer

Amazon S3

Answer

Amazon EFS

Answer

Amazon EBS gp3 volumes

Question 7

An SAP customer wants to reduce the cost of running a non-production SAP system on AWS. The system is used only during business hours (8 AM to 6 PM) on weekdays. What is the most cost-effective solution?

Accepted Answer

Use AWS Instance Scheduler to stop instances outside business hours.. Using AWS Instance Scheduler allows you to automatically stop instances outside business hours, reducing costs significantly for systems used only during specific times. Option A is incorrect because Reserved Instances are best for steady-state usage and would still incur costs for hours when the system is not needed. Option B is incorrect because Compute Savings Plans also require consistent usage to be cost-effective and do not eliminate charges for idle hours. Option C is incorrect because running On-Demand instances without scheduling does not reduce costs, as you pay for every hour regardless of usage.

Answer

Purchase Reserved Instances for 1-year term.

Answer

Purchase Compute Savings Plans for 3-year term.

Answer

Run the instances as On-Demand without any schedule.

Question 8

A company is migrating a large SAP ERP system to AWS using SAP HANA. They want to minimize downtime and ensure consistency. Which three approaches should they combine? (Choose THREE.)

Accepted Answer

Use AWS Snowball Edge for the initial data transfer. The correct combination involves Snowball Edge for the initial large data transfer (A), DMS with ongoing change data capture (D), and SAP HANA system replication for zero-downtime cutover (E). Snowball Edge handles the initial bulk load efficiently. DMS captures ongoing changes during migration. SAP HANA system replication provides continuous data synchronization for a seamless switch. Option B (DataSync) is redundant as DMS already handles ongoing replication. Option C (SMS) is designed for server-level migration, not for SAP HANA data. Thus, A, D, and E are the three approaches to combine.

Answer

Use AWS DataSync for ongoing replication

Answer

Use AWS Server Migration Service (SMS) for server replication

Question 9

An SAP administrator is migrating an on-premises SAP system to AWS using this IAM policy. When attempting to launch a new EC2 instance from an AMI stored in the S3 bucket, the launch fails. What is the likely cause?

Accepted Answer

The IAM policy does not include ec2:RunInstances.. The launch fails because the IAM policy does not include the ec2:RunInstances permission, which is required to launch new EC2 instances. Option A is incorrect because the ability to stop or start instances is not relevant to launching new instances. Option C is incorrect because the failure is due to the IAM policy, not the S3 bucket policy; the IAM policy may allow s3:GetObject but that does not overcome the lack of ec2:RunInstances. Option D is incorrect because describing instances is not a prerequisite for launching.

Answer

The policy does not allow stopping or starting instances.

Answer

The S3 bucket policy does not allow reading the AMI object.

Answer

The policy does not allow describing EC2 instances.

Question 10

A company is migrating an SAP Business Suite system to AWS. The system runs on AIX on IBM Power Systems. The company wants to rehost the system on AWS using a lift-and-shift approach. Which AWS service can replicate the AIX operating system to run on AWS?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) supports agent-based migration for AIX via the AWS Replication Agent. Option A (AWS CloudEndure Migration) has been rebranded as AWS MGN. Option B (AWS SMS) does not support AIX. Option C (AWS Database Migration Service) is for databases, not OS.

Answer

AWS CloudEndure Migration

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Question 11

A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for data transfer. The migration involves transferring 10 TB of data. Which AWS service is designed to accelerate data transfer over Direct Connect?

Accepted Answer

AWS DataSync. AWS DataSync is designed to accelerate data transfer over Direct Connect by optimizing network usage, performing automatic encryption, and managing retries. Amazon S3 Transfer Acceleration (Option A) is optimized for transfers over the internet using AWS edge locations, not Direct Connect. AWS VPN (Option B) provides a secure tunnel but does not accelerate bulk transfers. AWS Snowball (Option D) is an offline physical device, not for use with Direct Connect.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS VPN

Answer

AWS Snowball

Question 12

An SAP administrator executed the AWS CLI command shown in the exhibit. The EC2 instance i-0abcd1234efgh5678 is a SAP HANA database server. Which statement about the storage configuration is correct?

Accepted Answer

The data volume (/dev/sdf) will persist after instance termination.. /dev/sdf has DeleteOnTermination set to false, meaning it will not be deleted when the instance is terminated, preserving the data. Option A is incorrect because /dev/xvda will be deleted. Option B is incorrect because /dev/sdf is an EBS volume, not an instance store volume. Option D is incorrect because the command only shows block device mappings, not the root device type.

Answer

The root volume (/dev/xvda) will persist after instance termination.

Answer

The volume /dev/sdf is an instance store volume.

Answer

The instance is booting from an instance store volume.

Question 13

During the migration of an SAP HANA database to AWS, the migration team encounters high latency on the database connections. The team is using AWS Direct Connect. Which configuration change can help reduce latency?

Accepted Answer

Enable jumbo frames on the Direct Connect interface. Enabling jumbo frames reduces overhead by allowing larger packets, which can improve latency for large data transfers. Option B is incorrect because a VPN connection adds encapsulation overhead and can increase latency. Option C is incorrect because increasing bandwidth increases throughput but does not reduce latency; latency is affected by packet size and network path. Option D is incorrect because placing EC2 instances in the same Availability Zone reduces physical distance but does not guarantee reduced latency if the network path is not optimized.

Answer

Switch from Direct Connect to a VPN connection

Answer

Increase the bandwidth of the Direct Connect connection

Answer

Place the EC2 instances in the same Availability Zone

Question 14

Which THREE factors should be considered when selecting an EC2 instance type for an SAP HANA production system?

Accepted Answer

Memory (RAM) size. The correct answers are A, B, and C. SAP HANA is an in-memory database, so memory size (RAM) is critical. The instance must be SAP-certified to ensure compatibility and performance. Network bandwidth is important for HANA system replication and data transfer. Option D is incorrect because HANA uses EBS volumes for persistent storage, not instance store (which is ephemeral). Option E is incorrect because GPUs are not required for SAP HANA.

Answer

Instance store volumes

Answer

GPU capabilities

Question 15

A company runs an SAP HANA system on AWS. The system uses a three-node cluster with HANA System Replication (HSR) in a scale-out configuration. The cluster spans three Availability Zones. Which architecture ensures the highest availability for the SAP HANA database?

Accepted Answer

Use a cluster of nodes across three Availability Zones with HANA System Replication and automatic failover.. Deploying a three-node cluster across three Availability Zones with HANA System Replication and automatic failover maximizes availability by distributing the data across multiple AZs and ensuring automatic failover in case of an AZ failure. Option B is incorrect because HANA System Replication in active/active mode is not supported for scale-out configurations; typical HSR implementations use active/standby or multi-target replication. Option C is incorrect because Amazon RDS for SAP HANA does not exist; SAP HANA on AWS must be deployed on EC2 instances. Option D is incorrect because deploying all nodes in a single Availability Zone introduces a single point of failure, reducing availability compared to a multi-AZ deployment.

Answer

Configure HANA System Replication in active/active mode across all nodes.

Answer

Use Amazon RDS for SAP HANA with Multi-AZ deployment.

Answer

Deploy all nodes in a single Availability Zone with synchronous replication.
