PAS-C01 Operations and Maintenance Practice Test 25 — 15 Questions

Question 1

A company is running SAP on AWS and needs to ensure high availability for their SAP Central Services (ASCS) instance. They plan to use a multi-AZ deployment with a floating IP. Which AWS service should they use to manage the floating IP and failover?

Accepted Answer

Amazon Route 53. Option B is correct because Amazon Route 53 can be used to associate a DNS name with a health check and failover to a secondary IP in another AZ. Option A is wrong because Elastic Load Balancer (ELB) is for distributing traffic, not for floating IPs. Option C is wrong because AWS Global Accelerator improves performance, not floating IP failover. Option D is wrong because Amazon CloudFront is a CDN.

Answer

Elastic Load Balancer

Answer

AWS Global Accelerator

Answer

Amazon CloudFront

Question 2

A company is running an SAP S/4HANA system on AWS. During a planned maintenance window, the operations team needs to apply an SAP kernel patch that requires stopping all SAP instances. Which AWS service can be used to orchestrate the stop/start sequence of multiple EC2 instances and ensure proper dependencies are maintained?

Accepted Answer

AWS Systems Manager Automation. Option D is correct because AWS Systems Manager Automation can run scripts and workflows (e.g., stop instances in order) with error handling. Option A is wrong because AWS CloudFormation is for infrastructure provisioning, not ad-hoc operations. Option B is wrong because Amazon EC2 RunCommand is for individual commands, not complex orchestration. Option C is wrong because AWS Step Functions can orchestrate but is more suited for serverless workflows; it can call Lambda but not directly manage EC2 stop/start without custom code.

Answer

AWS Step Functions

Answer

AWS CloudFormation

Answer

Amazon EC2 Run Command

Question 3

A company runs SAP HANA on AWS and wants to implement a backup strategy using AWS Backint agent for SAP HANA. Which storage service is best suited for storing the backup files when using Backint?

Accepted Answer

Amazon S3. Option A is correct because AWS Backint for SAP HANA is designed to stream backups directly to Amazon S3. Option B is wrong because EBS volumes are for block storage, not the target for Backint. Option C is wrong because S3 Glacier is for archival, not for frequent backups. Option D is wrong because EFS is file storage, not the intended target.

Answer

Amazon S3 Glacier

Answer

Amazon EFS

Answer

Amazon EBS

Question 4

An SAP Basis administrator is troubleshooting a slow-running SAP HANA query. The administrator wants to identify which SQL statements are consuming the most CPU time in the HANA database. Which SAP HANA view or tool should they query?

Accepted Answer

M_ACTIVE_STATEMENTS. Option C is correct because the M_ACTIVE_STATEMENTS view shows currently executing statements with resource usage. Option A is wrong because M_SERVICE_REPLICATION is for replication status. Option B is wrong because M_TABLES shows table metadata. Option D is wrong because M_LOAD_HISTORY shows load history.

Answer

M_TABLES

Answer

M_LOAD_HISTORY

Answer

M_SERVICE_REPLICATION

Question 5

A company is running SAP on AWS and wants to automatically recover an unhealthy EC2 instance that hosts their SAP application. Which AWS feature should they configure to automatically restart the instance in the same Availability Zone if it fails?

Accepted Answer

EC2 Auto Recovery. Option B is correct because Amazon EC2 Auto Recovery automatically recovers an instance in the same AZ when it becomes impaired. Option A is wrong because Auto Scaling replaces instances across AZs, not necessarily the same AZ. Option C is wrong because a Cluster Placement Group is for low latency, not recovery. Option D is wrong because a Lifecycle Hook is for custom actions during scaling events.

Answer

Cluster Placement Group

Answer

Auto Scaling group

Answer

Lifecycle Hook

Question 6

An AWS administrator needs to monitor the CPU utilization of an EC2 instance running SAP NetWeaver. The instance type is r5.2xlarge. Which CloudWatch metric should the administrator use to track the CPU usage of the instance?

Accepted Answer

CPUUtilization. Option A is correct because CPUUtilization is the standard metric for EC2 CPU usage. Option B is wrong because NetworkIn is network traffic. Option C is wrong because DiskReadOps is disk I/O. Option D is wrong because Memory utilization is not a default metric; it requires a custom agent.

Answer

MemoryUtilization

Answer

NetworkIn

Answer

DiskReadOps

Question 7

A company runs SAP HANA on AWS and needs to perform a system copy from production to a test environment. The test environment is in a different AWS account. Which AWS service can be used to securely share the HANA backup files stored in Amazon S3 across accounts?

Accepted Answer

S3 bucket policy. Option D is correct because S3 bucket policies can grant cross-account access to the backup files. Option A is wrong because S3 Transfer Acceleration improves speed, not access control. Option B is wrong because VPC Peering is for network connectivity, not S3 access. Option C is wrong because AWS Direct Connect is for dedicated network connection.

Answer

VPC Peering

Answer

S3 Transfer Acceleration

Answer

AWS Direct Connect

Question 8

An organization runs SAP on AWS and needs to ensure that their SAP HANA database backups are encrypted at rest. Which AWS service should they use to manage the encryption keys?

Accepted Answer

AWS Key Management Service (KMS). Option C is correct because AWS KMS is the key management service for encryption keys. Option A is wrong because CloudHSM is a hardware security module, but KMS is the standard for key management. Option B is wrong because IAM is for identity, not encryption keys. Option D is wrong because ACM is for SSL/TLS certificates.

Answer

AWS CloudHSM

Answer

AWS Identity and Access Management (IAM)

Answer

AWS Certificate Manager

Question 9

A company is running SAP on AWS and needs to reduce the cost of their development and test systems. The systems are only needed during business hours on weekdays. Which AWS service can be used to automatically stop and start the EC2 instances on a schedule?

Accepted Answer

AWS Instance Scheduler. Option A is correct because AWS Instance Scheduler is a solution that automatically stops and starts instances based on a schedule. Option B is wrong because Auto Scaling is for scaling, not scheduling. Option C is wrong because Systems Manager Maintenance Windows are for patching. Option D is wrong because CloudWatch Alarms trigger based on metrics, not time-based schedules.

Answer

Amazon EC2 Auto Scaling

Answer

Amazon CloudWatch Alarms

Answer

AWS Systems Manager Maintenance Windows

Question 10

A company runs SAP HANA on AWS and needs to implement a disaster recovery (DR) strategy. The DR site must have a Recovery Time Objective (RTO) of 30 minutes and a Recovery Point Objective (RPO) of 15 minutes. Which two AWS services should be used together to achieve these objectives? (Choose TWO.)

Accepted Answer

SAP HANA System Replication. Option B (HANA System Replication) is correct because it provides near-synchronous replication with low RPO. Option D (Amazon EBS snapshots) is correct if combined with replication, but for RPO of 15 minutes, HANA replication is more suitable. However, the question expects two services: HANA System Replication (for real-time replication) and Amazon EBS snapshots (for additional recovery points). Option A is wrong because S3 is not used for HANA replication. Option C is wrong because DMS is for database migration, not DR. Option E is wrong because CloudEndure is for server-level replication, but not specifically for HANA.

Answer

AWS Database Migration Service

Answer

AWS CloudEndure Disaster Recovery

Answer

Amazon S3

Question 11

An SAP administrator is troubleshooting an issue where the SAP system is not responding. The administrator checks the AWS Management Console and finds that the EC2 instance status checks are failing. Which three actions should the administrator take to recover the instance? (Choose THREE.)

Accepted Answer

Check the system logs for errors. Option A (Stop and start the instance) is correct because it moves the instance to new hardware. Option C (Reboot the instance) is correct because it may resolve transient issues. Option E (Check system logs) is correct because it helps diagnose the root cause. Option B is wrong because attaching a new EBS volume won't fix the instance health. Option D is wrong because changing instance type might not help if the issue is underlying hardware.

Answer

Change the instance type

Answer

Attach a new EBS volume

Question 12

A company is planning to run SAP HANA on AWS. Which three are best practices for configuring the EC2 instance for SAP HANA? (Choose THREE.)

Accepted Answer

Enable CPU hyper-threading. Option A (Enable CPU hyper-threading) is correct for HANA performance. Option C (Use EBS-optimized instances) is correct for storage performance. Option D (Use placement groups) is correct for high network throughput. Option B is wrong because swap space is not recommended for HANA. Option E is wrong because T2/T3 instances are burstable and not suitable for production HANA.

Answer

Use burstable instance types (T2/T3)

Answer

Allocate swap space on the instance

Question 13

An SAP administrator attaches this IAM policy to a user. The user is unable to start an EC2 instance with ID i-0abcdef1234567890. What is the most likely cause?

Accepted Answer

The IAM policy is applied to a user who is working in a different AWS region than the one specified in the resource ARN.. Option D is correct because the resource ARN specifies us-east-1, but the user might be operating in a different region. Option A is wrong because the policy includes ec2:StartInstances. Option B is wrong because ec2:DescribeInstances is included. Option C is wrong because ec2:RebootInstances is not required for starting.

Answer

The IAM policy does not include the ec2:RebootInstances action.

Answer

The IAM policy does not include the ec2:DescribeInstances action.

Answer

The IAM policy does not include the ec2:StartInstances action.

Question 14

A company runs an SAP HANA database on an EC2 instance with EBS volumes. The operations team needs to ensure that snapshots of the database volumes are consistent. Which step should be taken before initiating the EBS snapshot?

Accepted Answer

Use hdbsql to execute BACKUP DATA FULL USING FILE ('/backup/snapshot_prep'). Option A is correct because running hdbsql with BACKUP DATA and USING FILE creates a snapshot-consistent backup. Option B is wrong because 'sync' only flushes OS buffers but does not guarantee HANA consistency. Option C is wrong because stopping HANA is excessive. Option D is wrong because EBS snapshots alone do not ensure application consistency.

Answer

Run the Linux 'sync' command on the instance

Answer

Stop the HANA database service

Answer

Create the EBS snapshot directly without any preparation

Question 15

An SAP system uses a shared file system mounted via EFS from multiple EC2 instances. The operations team notices that the file system is not performing well during peak loads. What is the most effective way to improve throughput without changing the application?

Accepted Answer

Change the EFS performance mode from General Purpose to Max I/O. Option B is correct because EFS performance mode can be set to 'max I/O' to increase throughput for parallel workloads. Option A is wrong because Provisioned Throughput is independent of General Purpose vs Max I/O. Option C is wrong because moving to FSx for Lustre is a different architecture. Option D is wrong because EBS is block storage and not suitable for shared access across multiple instances.

Answer

Enable Provisioned Throughput on the EFS file system

Answer

Replace EFS with an EBS Multi-Attach volume

Answer

Migrate the file system to Amazon FSx for Lustre
