PAS-C01 Practice Test 24 — 15 Questions

Question 1

An SAP administrator notices that the SAP HANA database is running out of memory frequently. The system is deployed on an EC2 instance with 512 GB of RAM. The HANA memory usage is peaking at 480 GB. What should the administrator do to resolve this issue?

Accepted Answer

Enable HANA memory overcommit and set the memory limit to 90%. Option D is correct because enabling HANA's memory overcommit can handle spikes beyond assigned memory. Option A is risky as it could cause swap thrashing. Option B would provide more headroom but is costly. Option C is not a viable solution.

Answer

Configure a swap file on the instance's root EBS volume

Answer

Migrate to an instance with more memory, such as x1e.32xlarge

Answer

Reduce the number of HANA table partitions

Question 2

An SAP administrator runs the AWS CLI command shown in the exhibit for an EC2 instance running SAP HANA. The administrator notices that the /dev/sdf volume does not have DeleteOnTermination set to true. What is the impact of this configuration?

Accepted Answer

The volume will persist after instance termination, preserving data.. The correct answer is C because if DeleteOnTermination is false, the EBS volume will persist after instance termination. This is important for data volumes like HANA data. Option A is incorrect because the volume remains in the account. Option B is incorrect because it will not be deleted. Option D is incorrect because the volume is attached.

Answer

The volume will be detached but not deleted.

Answer

The volume will be automatically deleted when the instance is terminated.

Answer

The volume cannot be attached to another instance.

Question 3

An SAP system is running on an EC2 instance with an instance profile that grants access to an S3 bucket. The application is unable to read a specific object from the bucket. What is the first step to troubleshoot the issue?

Accepted Answer

Check the IAM policy attached to the instance profile. Checking the IAM policy attached to the instance profile ensures the correct permissions are granted. Option B is wrong because security groups control network traffic, not S3 access. Option C is wrong because S3 bucket policies are separate from IAM. Option D is wrong because NACLs are for subnet traffic.

Answer

Check the security group associated with the instance

Answer

Check the network ACLs

Answer

Check the S3 bucket policy

Question 4

An SAP system is running on AWS with an SAP HANA database. The administrator needs to back up the HANA database to Amazon S3. Which AWS service or feature should be used to perform efficient incremental backups?

Accepted Answer

AWS Backup with the SAP HANA backup plan. Option A is correct. AWS Backup supports SAP HANA with incremental backups to S3. Option B is wrong because EBS snapshots are for volumes, not database-level backups. Option C is wrong because AWS Storage Gateway is for on-premises integration. Option D is wrong because S3 Transfer Acceleration speeds up uploads but does not manage backups.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Storage Gateway with volume gateway

Answer

Amazon EBS snapshots of the HANA data volumes

Question 5

An SAP administrator runs the AWS CLI command shown. The output shows /dev/sdf. Which SAP HANA volume is typically mounted at this device?

Accepted Answer

/hana/data. Option A is correct. The /dev/sdf device is commonly used for the /hana/data volume in SAP HANA on AWS. Option B is wrong because /hana/log is often /dev/sdg. Option C is wrong because /usr/sap is typically /dev/sdh. Option D is wrong because /hana/shared is usually on EFS or another device.

Answer

/hana/log

Answer

/usr/sap

Answer

/hana/shared

Question 6

A company wants to automate the deployment of SAP environments on AWS. Which AWS service should the company use to define the infrastructure as code?

Accepted Answer

AWS CloudFormation. Option A is correct because AWS CloudFormation allows defining infrastructure as code. Option B is wrong because AWS Elastic Beanstalk is for web applications, not SAP. Option C is wrong because OpsWorks is for Chef/Puppet. Option D is wrong because CodeDeploy is for application deployment, not infrastructure.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Elastic Beanstalk

Question 7

A company is migrating its SAP ERP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS architecture should they implement?

Accepted Answer

Configure a two-node cluster with a virtual IP (VIP) using AWS Route 53 health checks and failover. ASCS high availability requires a cluster with a virtual IP address managed by a load balancer or route table update. Option A is wrong because a single instance is not HA. Option B is wrong because Auto Scaling does not handle ASCS failover properly. Option D is wrong because Multi-AZ RDS is for databases, not ASCS.

Answer

Run ASCS on Amazon RDS for SAP with Multi-AZ

Answer

Deploy ASCS on a single large EC2 instance

Answer

Use an Auto Scaling group with a minimum of 2 instances

Question 8

An SAP administrator notices that the SAP application server is experiencing high latency when reading from the shared /sapmnt directory mounted from an Amazon EFS file system. The EFS file system is in General Purpose performance mode and uses Bursting throughput mode. The administrator checks CloudWatch metrics and sees that BurstCreditBalance is near zero. What is the most cost-effective solution to address the latency?

Accepted Answer

Enable Provisioned Throughput mode on the EFS file system. Option D is correct because switching to Provisioned Throughput mode ensures consistent throughput without relying on burst credits. Option A is wrong because switching to Max I/O performance mode does not increase throughput. Option B is wrong because EBS gp3 volumes are not shared across instances. Option C is wrong because increasing burst credit balance is not possible; burst credits are earned based on storage size.

Answer

Increase the size of the EFS file system to increase the burst credit balance

Answer

Mount the /sapmnt directory from an Amazon EBS gp3 volume instead

Answer

Change the EFS performance mode to Max I/O

Question 9

A company is designing a highly available SAP NetWeaver AS ABAP environment on AWS with a 2-node ASCS/ERS cluster. Which TWO of the following must be configured to ensure a successful failover? (Choose 2)

Accepted Answer

A shared file system (e.g., Amazon EFS) for /sapmnt. Options A and D are correct. A: A shared file system (e.g., EFS) is needed for /sapmnt. D: A virtual IP via Route53 or AWS CLI is required for client reconnection. B is wrong because EBS Multi-Attach is not supported for io1 volumes with Linux. C is wrong because each node needs its own instance store or EBS for local data. E is wrong because ASW is not an AWS service.

Answer

An AWS ASW (Automated SAP Workload) service

Answer

Amazon EBS io1 volumes with Multi-Attach enabled for the database

Answer

Each node must have its own /usr/sap//ASCS and /usr/sap//ERS directory on instance store

Question 10

A company is designing a disaster recovery solution for SAP HANA on AWS. The primary site is in us-east-1, and the DR site is in us-west-2. Which TWO strategies can be used to replicate HANA data to the DR region? (Choose TWO.)

Accepted Answer

Use AWS Database Migration Service (DMS) for ongoing replication. Options A and C are correct. SAP HANA System Replication can be configured across regions for continuous replication. AWS DMS can also replicate data to a target database in another region. Option B is wrong because EBS snapshots are not real-time and require manual copying. Option D is wrong because S3 Cross-Region Replication is for objects, not block storage. Option E is wrong because CloudEndure is for server migration, not HANA replication.

Answer

Copy EBS snapshots to the DR region using AWS CLI

Answer

Configure S3 Cross-Region Replication for HANA data files

Answer

Use AWS CloudEndure Disaster Recovery

Question 11

An SAP Basis team is designing a high-availability (HA) setup for SAP NetWeaver on AWS. They plan to use a shared file system for transport directories. Which storage solution provides the most cost-effective NFS share with support for automatic failover across Availability Zones?

Accepted Answer

Amazon FSx for NetApp ONTAP. Amazon FSx for NetWeaver (FSx for NetApp ONTAP) provides a fully managed NFS share with HA across AZs. Option A is wrong because EFS is a POSIX file system but not specifically optimized for SAP transport directories and may have cost implications. Option B is wrong because EBS can't be mounted across AZs. Option C is wrong because S3 is object storage, not a file system.

Answer

Amazon Elastic File System (EFS)

Answer

Amazon EBS Multi-Attach gp3 volume

Answer

Amazon S3 with AWS Storage Gateway file gateway

Question 12

Which THREE of the following are best practices for securing SAP systems on AWS?

Accepted Answer

Enable AWS CloudTrail to log all API calls. Option A is correct because security groups act as virtual firewalls for EC2 instances. Option C is correct because AWS KMS can be used to encrypt EBS volumes and S3 objects. Option E is correct because AWS CloudTrail provides audit logging of API calls. Option B is wrong because IAM users should not be used for SAP application authentication; instead, use SAP-specific authentication. Option D is wrong because storing secrets in source code is insecure; use AWS Secrets Manager instead.

Answer

Use IAM users to authenticate SAP system users

Answer

Store SAP system credentials in application source code

Question 13

An SAP administrator is planning a Disaster Recovery (DR) strategy for SAP HANA on AWS. The DR site is in a different AWS Region. Which AWS service can replicate SAP HANA data to the DR region with low Recovery Point Objective (RPO)?

Accepted Answer

SAP HANA System Replication with log shipping. Option A is correct. SAP HANA System Replication with log shipping can provide a low RPO by continuously replicating data to another region. Option B is wrong because EBS snapshots are periodic and may not achieve low RPO. Option C is wrong because S3 cross-region replication is object-level, not database-level. Option D is wrong because AWS Database Migration Service is for migrations, not ongoing replication for DR.

Answer

Amazon EBS snapshots copied to the DR region

Answer

AWS Database Migration Service (DMS) with ongoing replication

Answer

Amazon S3 cross-region replication

Question 14

An SAP administrator notices that the SAP application server performance degrades during peak hours. The application servers are running on EC2 instances with gp2 EBS volumes. The administrator suspects the EBS volumes are experiencing burst bucket depletion. Which action should the administrator take to improve performance?

Accepted Answer

Change the volume type to gp3 and adjust the IOPS and throughput settings.. Option C is correct because changing the volume type to gp3 provides baseline performance without burst credits, eliminating burst bucket depletion. Option A is wrong because gp2 volumes still use burst credits. Option B is wrong because Provisioned IOPS is more expensive and may not be needed. Option D is wrong because instance store volumes are ephemeral and not suitable for persistent data.

Answer

Increase the size of the gp2 volumes to increase the baseline IOPS.

Answer

Move the data to instance store volumes for better performance.

Answer

Change the volume type to io1 and provision high IOPS.

Question 15

A company is deploying SAP on AWS and needs to ensure high availability for the SAP application servers. Which TWO strategies can be used to achieve this? (Choose TWO.)

Accepted Answer

Use an Auto Scaling group with an Application Load Balancer. Option A and Option B are correct. Deploying across multiple Availability Zones and using an Auto Scaling group with a load balancer provides HA and scalability. Option C is wrong because a single instance does not provide HA. Option D is wrong because EBS Multi-Attach is limited and not for application servers. Option E is wrong because RDS is for databases, not application servers.

Answer

Use Amazon RDS Multi-AZ for the application tier

Answer

Use a single large EC2 instance with an Elastic IP

Answer

Attach the same EBS volume to multiple instances
