PAS-C01 Design of SAP Workloads on AWS Practice Test 33 — 15 Questions

Question 1

A company is deploying SAP S/4HANA on AWS and needs to ensure high availability for the database layer. Which TWO actions should the company take?

Accepted Answer

Configure SAP HANA System Replication across two Availability Zones. Option B is correct because SAP HANA System Replication (HSR) is the native SAP high-availability mechanism that continuously replicates data and redo logs from a primary to a secondary HANA node, and placing the two nodes in separate Availability Zones provides resilience against an AZ-level failure with automatic or manual takeover. Option D is correct because HANA's data and log volumes demand very high, consistent IOPS and low latency, and Amazon EBS io2 Block Express volumes deliver up to 256,000 IOPS and sub-millisecond latency with high durability, making them the recommended storage for production HANA on AWS. Option A is not a high-availability action for the database layer; S3 Standard-IA is a backup/archival storage class and does not provide failover or continuous availability. Option C is wrong because Amazon EFS is a shared NFS file system not certified or performant enough for HANA data volumes, which require block storage. Option E is wrong because EC2 Auto Scaling is designed for stateless, horizontally scalable workloads and cannot be used to fail over a stateful, vertically scaled HANA database instance.

Answer

Store HANA backups in Amazon S3 Standard-IA

Answer

Use Amazon EFS as the data volume for HANA

Answer

Enable EC2 Auto Scaling for the HANA instance

Question 2

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. In SAP HANA on AWS, the /dev/sdf device is typically mapped to the /hana/data volume. This is because AWS recommends using separate EBS volumes for /hana/data, /hana/log, and /hana/shared, and the default naming convention assigns /dev/sdf to the data volume in many SAP HANA deployment templates and AWS Quick Starts.

Answer

/hana/log

Answer

/usr/sap

Answer

/hana/shared

Question 3

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. When the health check associated with the primary record fails, Route 53 automatically fails over to the secondary record. In this configuration, the primary record is an ALIAS record pointing to a load balancer, and the secondary record is a CNAME record. Since the primary is unhealthy, Route 53 returns the secondary CNAME record, directing clients to the failover endpoint.

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 4

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.. The gp2 volume type uses a credit-based burst model where performance degrades once the burst bucket is depleted, especially under sustained high I/O. Changing to gp3 provides a baseline performance that does not rely on burst credits, and you can independently provision higher IOPS and throughput without increasing storage size, directly addressing the performance degradation during peak hours.

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 5

A company is planning to run SAP HANA on AWS and needs to ensure that the database meets the required memory and CPU performance. Which instance family should the company choose for the SAP HANA database?

Accepted Answer

X1e instances. SAP HANA is an in-memory database that requires large amounts of RAM and high memory bandwidth to keep all data in memory for real-time processing. The X1e instance family is specifically designed for high-memory workloads like SAP HANA, offering up to 4 TB of memory and high-frequency Intel Xeon processors, making it the only instance family among the options that meets SAP's certified memory and CPU requirements.

Answer

T3 instances

Answer

M5 instances

Answer

C5 instances

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. AWS CloudFormation is the correct choice because it allows you to define your entire SAP infrastructure—including EC2 instances, VPCs, security groups, and storage—as code using JSON or YAML templates. This enables repeatable, version-controlled, and automated deployments of SAP environments, which is essential for infrastructure as code (IaC) practices.

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Answer

AWS Elastic Beanstalk

Question 7

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 C is correct because an Auto Scaling group with an Application Load Balancer provides high availability for SAP application servers by automatically replacing failed instances and distributing incoming traffic across healthy targets in multiple subnets. Option E is correct because deploying application servers across multiple Availability Zones protects against a single AZ failure, which is a fundamental AWS high-availability design practice for SAP application tiers. Option A is incorrect because Amazon RDS Multi-AZ applies to the database tier, not the SAP application server tier. Option B is incorrect because a single large EC2 instance with an Elastic IP is a single point of failure and does not provide high availability. Option D is incorrect because standard EBS volumes cannot be attached to multiple EC2 instances simultaneously; only specific multi-attach-capable EBS volumes support that, and it is not a valid SAP application high-availability strategy.

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

Question 8

An SAP administrator applies the IAM policy shown in the exhibit to an IAM user. The administrator reports that the user can start and stop EC2 instances but cannot tag them. Why is the user unable to tag instances?

Accepted Answer

The policy does not include the ec2:CreateTags action.. The IAM policy explicitly grants ec2:StartInstances and ec2:StopInstances actions but does not include ec2:CreateTags. Without the ec2:CreateTags action, the user lacks the required permission to create or modify tags on EC2 instances, even though they can start and stop them.

Answer

The user does not have permission to describe instances.

Answer

The resource ARN is too restrictive.

Answer

There is an implicit deny for all actions not listed.

Question 9

An SAP administrator runs the command shown in the exhibit. The volume is attached to an EC2 instance. The administrator plans to increase the volume size to 1000 GiB. After resizing, the volume type remains gp2. What is the expected baseline IOPS for the resized volume?

Accepted Answer

3000 IOPS. Gp2 volumes have a baseline IOPS of 3 IOPS per GiB, up to a maximum of 16,000 IOPS. For a 1000 GiB gp2 volume, the calculation is 1000 × 3 = 3000 IOPS, which is below the 16,000 IOPS cap, so the expected baseline IOPS is exactly 3000.

Answer

4500 IOPS

Answer

16,000 IOPS

Answer

1500 IOPS

Question 11

A company runs SAP Business Suite on AWS with a large SAP HANA database. They observe high memory utilization and need to scale up. Which instance type should they choose to provide the highest memory capacity for SAP HANA?

Accepted Answer

u-12tb1.112xlarge. The u-12tb1.112xlarge is the correct choice because it is part of AWS's bare metal 'u' instance family, specifically designed for large in-memory databases like SAP HANA, offering up to 12 TB of RAM. This instance type provides the highest memory capacity among AWS instances, making it suitable for scaling up SAP HANA when high memory utilization is observed.

Answer

r5.24xlarge

Answer

x1e.32xlarge

Answer

m5.24xlarge

Question 12

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. AWS requires SAP HANA to run only on EC2 instance types that have been certified by SAP and listed in the SAP HANA Hardware Directory. This certification ensures the instance meets SAP's strict memory, CPU, and I/O requirements for production workloads. Selecting a non-certified instance can lead to unsupported configurations, performance issues, and loss of SAP support.

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 13

A company runs SAP NetWeaver on AWS and notices that the application server is experiencing high CPU utilization during peak hours. They need to scale out the SAP application tier. What is the best approach?

Accepted Answer

Use an Auto Scaling group to automatically launch additional application servers and register them with the SAP application load balancer. It provides an automated, elastic scaling solution for the SAP application tier. An Auto Scaling group can dynamically launch additional EC2 instances based on CPU utilization metrics and automatically register them with the SAP application load balancer, ensuring seamless distribution of incoming user traffic across multiple application servers without manual intervention.

Answer

Use AWS Global Accelerator to distribute traffic

Answer

Increase the instance size of the existing application server

Answer

Manually launch additional EC2 instances and configure them as application servers

Question 14

Which TWO actions are recommended for securing an SAP system on AWS? (Choose TWO.)

Accepted Answer

Enable encryption at rest for EBS volumes and RDS instances. Using security groups to control traffic and enabling encryption at rest are key security measures. Option B is wrong because disabling CloudTrail reduces visibility. Option D is wrong because public subnets are not recommended. Option E is wrong because default VPC security groups are too permissive.

Answer

Disable AWS CloudTrail to reduce logging overhead

Answer

Place all SAP servers in a public subnet for easier management

Answer

Use the default VPC security group for all SAP instances

Question 15

Which THREE factors should be considered when sizing an EC2 instance for SAP HANA? (Choose THREE.)

Accepted Answer

Total memory available on the instance. Option A is correct because SAP HANA is an in-memory database, so the total memory available on the instance must be large enough to hold the entire working dataset in RAM, making memory the primary sizing factor. Option C is correct because only EC2 instance types that are SAP HANA certified (listed in the SAP HANA hardware directory and AWS SAP HANA certified instances) are supported for production HANA deployments, so certification must be verified before sizing. Option D is correct because HANA performance depends on adequate vCPU count for query processing and sufficient network throughput (e.g., up to 100 Gbps on larger instances) for scale-out and data replication traffic. Option B is not correct because SAP HANA does not use GPU acceleration for its core in-memory calculations; it relies on CPU and memory. Option E is not correct because HANA data resides in memory and persists to EBS or other supported storage, not to EC2 instance store, which is ephemeral and not part of HANA sizing criteria.

Answer

GPU acceleration for HANA calculations

Answer

Instance store availability for HANA data
