PAS-C01 Practice Test 26 — 15 Questions

Question 1

An SAP system on AWS is experiencing performance issues due to high I/O wait times on the database server. The database runs on an EC2 instance with EBS volumes. Which THREE actions can improve the I/O performance? (Choose THREE.)

Accepted Answer

Use instance store SSDs for the database logs. Option A, Option C, and Option D are correct. Using EBS-optimized instances ensures dedicated bandwidth. Increasing EBS IOPS provides more throughput. Using instance store SSDs offers very low latency. Option B is wrong because RAID 0 of gp2 volumes still uses burst credits. Option E is wrong because reducing volume size decreases performance.

Answer

Reduce the volume size to increase the burst duration

Answer

Configure RAID 0 of multiple gp2 volumes

Question 2

A company is planning to run SAP HANA on AWS. What is the recommended practice for sizing the EC2 instance for SAP HANA?

Accepted Answer

Select an instance type from the SAP HANA certified list on AWS. SAP HANA requires that the instance be certified for SAP HANA on AWS. Option A is wrong because memory is just one factor. Option B is wrong because vCPU count is not the primary criterion. Option D is wrong because network bandwidth is secondary.

Answer

Choose an instance with the highest network bandwidth

Answer

Choose an instance with the highest vCPU count

Answer

Choose an instance with the most memory available

Question 3

A company runs SAP HANA on AWS using an m5.24xlarge instance. The storage is configured with multiple EBS io1 volumes striped with LVM. Recently, the database performance has degraded. CloudWatch shows that the EBS write latency averages 5 ms, and the queue depth is consistently below 1. What is the most likely cause of the performance degradation?

Accepted Answer

The LVM stripe width is misconfigured causing uneven I/O distribution. Option C is correct because if the stripe width is not optimal, the I/O may not be distributed evenly, leading to hot spots. Option A is wrong because io1 volumes can handle high IOPS. Option B is wrong because 5 ms latency is acceptable. Option D is wrong because EBS-optimized instances by default provide dedicated bandwidth.

Answer

The EBS-optimized instance feature is not enabled

Answer

The EBS volume type should be changed to gp3

Answer

The EBS write latency is too high and requires a larger instance

Question 4

A company is migrating an SAP Business Suite system to AWS. The system has a large database and requires high network throughput between the application and database tiers. Which Amazon EC2 placement group strategy should be used?

Accepted Answer

Cluster placement group. Option C is correct because a cluster placement group provides low-latency, high-throughput connectivity within a single Availability Zone, which is optimal for application and database tier communication. Option A is wrong because spread placement groups are for high availability and reduce correlated failures, not for low latency. Option B is wrong because partition placement groups are for large distributed workloads. Option D is wrong because no placement group would not guarantee low latency.

Answer

Spread placement group

Answer

Partition placement group

Answer

No placement group

Question 5

A company is planning to run SAP NetWeaver on AWS. Which TWO services are recommended for monitoring the SAP system? (Choose TWO.)

Accepted Answer

Amazon CloudWatch with SAP monitoring agent. Options A and C are correct. Amazon CloudWatch can monitor SAP metrics, and SAP Solution Manager can be integrated with AWS for comprehensive monitoring. Option B is wrong because AWS Config is for configuration auditing. Option D is wrong because AWS Trusted Advisor provides best-practice checks, not real-time monitoring. Option E is wrong because Amazon Inspector is for security assessment.

Answer

Amazon Inspector

Answer

AWS Trusted Advisor

Answer

AWS Config

Question 6

Which THREE storage options are supported for SAP HANA data files on AWS? (Select THREE.)

Accepted Answer

NVMe instance store SSDs on i3en instances. SAP HANA supports EBS io2, EBS gp3 (with sufficient IOPS), and NVMe instance store on certified instances. EFS and S3 are not supported for HANA data files.

Answer

Amazon EFS

Answer

Amazon S3

Question 7

An SAP system on AWS requires persistent storage for its database logs. Which storage option should be used to meet the performance requirements of SAP HANA?

Accepted Answer

Amazon EBS io2 Block Express volumes. Option C is correct because SAP HANA requires high-performance, low-latency storage, and EBS io2 Block Express volumes provide consistent low latency and high IOPS. Options A, B, and D do not meet the performance requirements.

Answer

Instance store volumes

Answer

Amazon S3

Answer

Amazon EFS

Question 8

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 9

An SAP administrator configures Route 53 failover routing as shown. The health check associated with the primary record is failing. What will happen to client requests for sap.example.com?

Accepted Answer

Route 53 will return the secondary CNAME record. Option B is correct. With failover routing, when the primary health check fails, Route 53 returns the secondary record. Option A is wrong because Route 53 does not failover to a different record type. Option C is wrong because the secondary record exists. Option D is wrong because Route 53 uses the secondary record, not return an error.

Answer

Route 53 will return the ALIAS record for the primary load balancer

Answer

Route 53 will return an error

Answer

Route 53 will return both records

Question 10

A company is designing a disaster recovery (DR) strategy for its SAP landscape on AWS. The DR site must be in a different AWS Region. Which TWO options can be used to replicate the SAP HANA database to the DR Region? (Choose TWO.)

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication. Option A and Option D are correct. SAP HANA System Replication can replicate to a different region using log shipping. AWS DMS can also replicate data to a target in another region. Option B is wrong because EBS snapshots are per-region and cannot be directly copied across regions without manual steps. Option C is wrong because S3 Cross-Region Replication replicates objects, not database transactions. Option E is wrong because RDS is not used for SAP HANA.

Answer

Amazon RDS Multi-Region replica

Answer

Amazon S3 Cross-Region Replication for HANA backup files

Answer

Amazon EBS snapshot copy to the DR Region

Question 11

An SAP administrator notices that the SAP HANA database backups to Amazon S3 are failing intermittently with timeout errors. The backup script uses the AWS CLI to copy files to an S3 bucket. What is the most likely cause and solution?

Accepted Answer

The backup files are large and the CLI command does not use multipart upload; use multipart upload and increase timeout values. Intermittent timeouts may be due to network connectivity issues or insufficient retries. Using multipart upload for large files and enabling retries can resolve this. Option A is wrong because S3 bucket policies do not cause timeouts. Option B is wrong because S3 Transfer Acceleration is for speed, not timeouts. Option D is wrong because S3 lifecycle policies do not affect uploads.

Answer

The S3 bucket policy is too restrictive, modify the policy

Answer

The S3 bucket has a lifecycle policy that deletes objects too quickly

Answer

S3 Transfer Acceleration is not enabled, enable it

Question 12

A company is planning to migrate their SAP system to AWS. They need to ensure that the SAP application servers and database servers are in the same AWS Region but in different Availability Zones for high availability. The network latency between Availability Zones must be minimal. Which AWS service should be used to connect the instances?

Accepted Answer

Use the default VPC network within the same VPC spanning multiple Availability Zones. Option A is correct because AWS uses a redundant, high-bandwidth, low-latency network between Availability Zones. Option B is wrong because VPC Peering is used for connecting different VPCs. Option C is wrong because Direct Connect is for on-premises connections. Option D is wrong because Transit Gateway is for hub-and-spoke connectivity, not needed for within a VPC.

Answer

Set up VPC Peering between the Availability Zones

Answer

Establish an AWS Direct Connect connection

Answer

Use AWS Transit Gateway to connect the subnets

Question 13

A company is designing a new SAP S/4HANA workload on AWS. Which storage service should be used for the SAP HANA data volume to meet the required throughput and latency for production systems?

Accepted Answer

Amazon EBS io2 Block Express volumes. Option B is correct because SAP HANA requires high IOPS and low latency, which is best provided by Amazon EBS io2 Block Express volumes with provisioned IOPS. Option A is wrong because EBS gp3 may not provide sufficient performance for large production HANA systems. Option C is wrong because S3 is object storage, not block storage. Option D is wrong because EFS is file storage, not block storage.

Answer

Amazon S3

Answer

Amazon EFS

Answer

Amazon EBS gp3 volumes

Question 14

A company is using SAP S/4HANA on AWS and wants to optimize costs. Which THREE actions would help reduce costs without impacting performance? (Choose THREE.)

Accepted Answer

Implement automatic start/stop for development and test instances. Options A, C, and E are correct. Using Reserved Instances for predictable workloads reduces cost. Rightsizing instances ensures you are not over-provisioned. Automating start/stop for non-production instances saves costs. Option B is wrong because gp2 is less expensive than io2 but may not meet performance requirements. Option D is wrong because Dedicated Hosts are more expensive.

Answer

Use Dedicated Hosts for better isolation

Answer

Replace io2 Block Express volumes with gp2 volumes

Question 15

Which TWO of the following are valid considerations when designing the network for SAP workloads on AWS? (Select TWO.)

Accepted Answer

Enable jumbo frames on the VPC for SAP application tier. SAP systems require jumbo frames to improve network performance, and placement groups can reduce latency. NACLs are stateless and can be used for security, but the question asks for design considerations.

Answer

Use a single subnet for all SAP tiers to simplify routing

Answer

Use a public subnet for the SAP database tier

Answer

Disable VPC Flow Logs to save costs
