PAS-C01 Practice Test 26 — 15 Questions

Question 1

A company is migrating its SAP system to AWS and wants to use a high-availability setup for the database layer. Which AWS service should the company use to achieve automatic failover for SAP HANA?

Accepted Answer

Amazon Route 53 with health checks. Amazon Route 53 can be configured with DNS failover using health checks to automatically redirect traffic to a standby SAP HANA database in the event of a primary failure. Option A is wrong because Amazon CloudFront is a content delivery network, not relevant for database failover. Option B is wrong because Elastic Load Balancing is designed for distributing traffic across multiple instances, not for database layer failover. Option D is wrong because AWS Global Accelerator improves application performance by routing traffic over the AWS global network, but it does not provide automatic failover for SAP HANA.

Answer

Amazon CloudFront

Answer

Elastic Load Balancing (ELB)

Answer

AWS Global Accelerator

Question 2

Refer to the exhibit. An IAM policy is attached to a role used by AWS DMS to write data to an S3 bucket. The migration fails with an access denied error. What is the most likely cause?

Accepted Answer

The policy does not include s3:AbortMultipartUpload.. DMS needs s3:PutObject and s3:AbortMultipartUpload actions. Option A is incorrect because the bucket exists. Option C is incorrect because encryption settings are not shown. Option D is incorrect because the policy allows PutObject.

Answer

The policy does not allow s3:PutObject.

Answer

The bucket has default encryption enabled.

Answer

The bucket name is incorrect.

Question 3

A company is migrating its SAP HANA database to AWS. The migration requires minimal downtime and data consistency. Which THREE steps should the company take to achieve this?

Accepted Answer

Use AWS DMS with change data capture (CDC) for ongoing replication.. To achieve minimal downtime and data consistency when migrating an SAP HANA database to AWS, the company should: Use AWS DMS with change data capture (CDC) for ongoing replication (B), create the target HANA database and schema in advance (C), and perform a full load of the data using AWS DMS before enabling CDC (D). A full backup and restore (A) would cause downtime, and disabling logging (E) is incorrect as it would compromise data consistency and recovery.

Answer

Take a full backup of the source database and restore it on the target.

Answer

Disable all logging on the source database to reduce overhead.

Question 4

Question 8

During the migration of an SAP NetWeaver system, the team notices that the application server performance is degraded after migrating to AWS. The system uses AWS EBS volumes for storage. Which of the following is the most likely cause of the performance degradation?

Accepted Answer

The EBS volumes have insufficient provisioned IOPS for the workload.. If EBS volumes are not provisioned with sufficient IOPS, the application server may experience performance degradation. EBS-optimized instances and appropriate volume types are important. EBS volumes are typically designed for durability, and encryption does not cause performance degradation.

Answer

The EBS volumes are using the wrong volume type.

Answer

The EBS volumes are not encrypted.

Answer

The EBS volumes are not EBS-optimized.

Question 9

A company is performing a large-scale migration of multiple SAP systems to AWS. They need to automate the replication of servers from on-premises to AWS while minimizing downtime. Which AWS service should they use to replicate entire servers (OS, applications, and data) in real-time?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS Application Migration Service (AWS MGN) replicates entire servers in real-time, enabling automated migration with minimal downtime. Option B is correct. Option A (AWS CloudFormation) is for infrastructure as code, not replication. Option C (AWS DataSync) is for file storage, not full server replication. Option D (AWS Database Migration Service) is for databases only.

Question 10

A company is migrating on-premises servers to AWS. After migrating, the administrator runs the AWS CLI command shown in the exhibit. The company wants to ensure that all EC2 instances are in the 'running' state. Which action should the administrator take?

Accepted Answer

Run aws ec2 start-instances --instance-ids i-1a2b3c4d5e6f7g8h. The instance with ID i-1a2b3c4d5e6f7g8h is in a stopped state. To transition it to the 'running' state, the administrator should use the start-instances command. Option A is correct because it starts the stopped instance. Option B (stop-instances) would stop running instances, which is not the desired action. Option C (reboot-instances) would reboot a running instance, but this instance is stopped. Option D (terminate-instances) would permanently delete the instance, which is not the goal.

Answer

Run aws ec2 stop-instances --instance-ids i-0a1b2c3d4e5f6g7h

Answer

Run aws ec2 reboot-instances --instance-ids i-2a3b4c5d6e7f8g9h

Place the database tier in subnets with a NAT Gateway

Answer

Place the database tier in subnets with an Internet Gateway

Answer

Place all tiers in public subnets

Question 14

Which THREE factors should be considered when choosing an instance type for an SAP HANA database on AWS? (Select THREE.)

Accepted Answer

Memory size of the instance. Options A, B, and E are correct. Memory size (A) is critical because SAP HANA is an in-memory database. The instance must be certified for SAP HANA (B) to ensure compatibility and support. Network throughput (E) is important for data replication and client access. Option C is incorrect because the number of attachable EBS volumes is not a primary selection criterion for SAP HANA. Option D is incorrect because GPU capabilities are not required for SAP HANA.

Answer

Number of EBS volumes that can be attached

Answer

GPU capabilities of the instance

Question 15

Which TWO components are typically migrated as part of an SAP workload migration to AWS?

Accepted Answer

SAP Central Services (ASCS/SCS).. When migrating an SAP workload to AWS, the key components that are typically migrated include SAP Central Services (ASCS/SCS) and the SAP HANA database. These are core parts of the SAP system. Option A is incorrect because AWS KMS encryption keys are infrastructure security components, not part of the workload itself. Option C is incorrect because AWS Direct Connect is a network connectivity service, not migrated. Option D is incorrect because IAM roles and policies are AWS access control mechanisms, not workload components.

Answer

AWS KMS encryption keys.

Answer

AWS Direct Connect virtual interface.

Answer

IAM roles and policies.
