PAS-C01 Practice Exam 70 — 20 Questions

Question 1

A company is running SAP HANA on AWS and wants to implement a disaster recovery strategy with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 2 hours. The primary site is in us-east-1, and the DR site is in us-west-2. Which two actions should the company take to meet these objectives? (Choose TWO.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Set up SAP HANA System Replication (HSR) in async mode between the two regions.. SAP HANA System Replication (HSR) in async mode can achieve an RPO of less than 15 minutes by continuously replicating log data to the DR region. Option E is correct because pre-configuring EC2 instances with the same SAP HANA software and configuration in the DR region minimizes the time needed to bring up the DR system, helping meet the 2-hour RTO. Option B is incorrect because daily snapshots cannot achieve a 15-minute RPO. Option C is incorrect because AWS CloudEndure Disaster Recovery is not optimized for SAP HANA and may not meet the RPO/RTO requirements. Option D is incorrect because AWS Backup does not support HANA log replication and cannot achieve the required RPO.

Answer

Take daily snapshots of the HANA volumes and copy them to the DR region.

Answer

Use AWS CloudEndure Disaster Recovery to replicate the entire server.

Answer

Use AWS Backup to schedule cross-region backups of the HANA database.

Question 2

An SAP administrator is troubleshooting a high CPU utilization issue on an SAP application server running on an Amazon EC2 instance. The administrator suspects a specific ABAP program is consuming excessive resources. Which AWS service can be used to capture detailed performance metrics and identify the process?

Accepted Answer

Amazon CloudWatch Agent. The Amazon CloudWatch Agent can be installed on an EC2 instance to collect detailed OS-level metrics, including CPU utilization per process, which can help identify the specific ABAP program consuming excessive resources. Option A is incorrect: AWS CloudTrail records API activity, not performance metrics. Option C is incorrect: AWS Config monitors configuration changes and compliance, not CPU usage. Option D is incorrect: Amazon VPC Flow Logs capture network traffic metadata, not CPU utilization.

Answer

AWS CloudTrail

Answer

AWS Config

Answer

Amazon VPC Flow Logs

Question 3

Which THREE of the following are valid considerations when designing an SAP HANA backup strategy on AWS?

Accepted Answer

Use EBS snapshots for backing up HANA data volumes.. EBS snapshots provide a consistent, point-in-time backup of HANA data volumes when the database is in backup mode (e.g., using hdbsql to create a snapshot). This method is supported by SAP and AWS, and it allows for fast recovery by restoring the entire volume without needing to replay transaction logs from a separate backup.

Answer

Back up HANA data directly to Amazon S3 using standard tools.

Answer

Replicate backups to another AWS Region using S3 Cross-Region Replication.

Question 4

A company is migrating a 10 TB SAP HANA database to AWS. They have a limited time window and need to minimize migration time. The database is running on a physical server with 1 Gbps network link to AWS. Which migration strategy is MOST suitable?

Accepted Answer

Use AWS Snowball Edge to transfer the database files offline. AWS Snowball Edge provides a high-capacity physical device for offline data transfer, avoiding network bandwidth limitations. Option A is wrong because AWS Direct Connect requires setup time and still is limited by 1 Gbps bandwidth, which would still result in long transfer times for 10 TB. Option C is wrong because AWS SCT is for schema conversion, not data transfer. Option D is wrong because AWS DMS over a 1 Gbps link would take too long for 10 TB of data.

Answer

Use AWS Direct Connect to increase bandwidth before migration

Answer

Use AWS SCT to convert the database and then use DMS

Answer

Use AWS DMS over the existing network link

Question 5

An SAP system on AWS uses an Application Load Balancer (ALB) to distribute traffic to multiple EC2 instances. The operations team wants to enable sticky sessions (session affinity) for the ALB. Which TWO steps are required? (Choose TWO.)

Accepted Answer

Set the stickiness duration in seconds. To enable sticky sessions on an ALB, two steps are required: First, enable stickiness (session affinity) at the target group level. Second, set the stickiness duration, which defines how long the session remains sticky. Option A is correct because setting the duration in seconds is a necessary configuration. Option E is correct because stickiness must be enabled on the target group. Option B (configure proxy protocol policy) is not related to stickiness; it is used to preserve client IP information. Option C (enable cross-zone load balancing) distributes traffic across zones but does not affect stickiness. Option D (create a custom cookie on the application server) is not required because the ALB can generate its own cookie (AWSALB) when stickiness is enabled on the target group.

Answer

Configure a proxy protocol policy

Answer

Enable cross-zone load balancing

Answer

Create a custom cookie on the application server

Question 6

A company runs an SAP HANA database on an EC2 instance with a large EBS volume. The volume is approaching its maximum capacity. The operations team needs to increase the storage size without downtime. What is the most efficient way to achieve this?

Accepted Answer

Use the AWS Management Console, CLI, or API to modify the existing EBS volume to increase its size while the instance is running.. AWS allows you to modify EBS volumes (including increasing size) while they are attached and in use, without downtime. Option B is wrong because using rsync to copy data would require downtime for consistency and is less efficient. Option C is wrong because it requires stopping the instance. Option D is wrong because it adds complexity and cost without being the most efficient method.

Answer

Create a new larger EBS volume and use rsync to copy data while the instance is running, then remount.

Answer

Stop the EC2 instance, detach the current EBS volume, create a new larger volume from a snapshot, attach it, and start the instance.

Answer

Add an additional EBS volume and use LVM to extend the logical volume.

Question 7

A company has an SAP HANA database running on an EC2 instance with multiple EBS volumes striped using LVM. The database is experiencing high latency during peak hours. Monitoring shows that the EBS volumes have a high Average Queue Length (avgqueue) and are frequently hitting the IOPS limit. The volumes are gp2 with 3000 IOPS each. The operations team wants to improve performance without increasing storage size. What should they do?

Accepted Answer

Change the volume type to gp3 and increase the IOPS and throughput.. Gp3 volumes provide a higher baseline IOPS (3000) than gp2 at the same storage size, and allow increasing IOPS and throughput independently without increasing storage. This addresses the high latency and IOPS limit issue without requiring additional volume size. Option A is wrong because io2 Block Express is designed for very high performance and may be excessive for this scenario, also likely increasing cost. Option B is wrong because instance store is ephemeral and not suitable for persistent database storage. Option D is wrong because adding more gp2 volumes would increase the total IOPS (since each gp2 volume has 3000 IOPS) and could help if the bottleneck is at the volume level, but gp3 provides a more cost-effective and simpler solution without adding more volumes.

Answer

Change the volume type to io2 Block Express with higher IOPS.

Answer

Migrate the database to an instance store-backed instance.

Answer

Add more gp2 volumes to the LVM stripe set.

Question 8

A company runs SAP HANA on AWS and uses AWS Systems Manager to automate patching of the operating system. After a recent patching cycle, the SAP HANA database failed to start. The administrator checked the logs and found that the HANA service was not starting due to a missing library dependency. What should the administrator do to prevent this issue in future patching cycles?

Accepted Answer

Test patches in a non-production environment and create a new AMI after successful validation. Testing patches in a non-production environment before applying them to production allows the administrator to identify issues like missing library dependencies. After successful validation, creating a new AMI ensures that all patches and dependencies are captured consistently, preventing the HANA database from failing to start due to missing libraries.

Answer

Use AWS Systems Manager Patch Manager to apply patches but exclude the library in question

Answer

Create a script to reinstall the missing library after patching

Answer

Set up a maintenance window that stops HANA before patching and starts it after

Question 9

A company is migrating a monolithic application to AWS. The application has a relational database with complex queries and requires low-latency read replicas. Which database migration strategy minimizes downtime and supports heterogeneous migrations?

Accepted Answer

Use AWS Database Migration Service (DMS) with ongoing replication.. AWS Database Migration Service (DMS) supports heterogeneous migrations (e.g., from Oracle to Amazon Aurora) and can minimize downtime by using ongoing replication to keep the source and target synchronized during the migration. Option A is incorrect because AWS Backup is a backup/restore service, not a live migration tool, and typically requires downtime. Option B is incorrect because AWS Schema Conversion Tool (SCT) is used for schema conversion, not for the actual data migration; it is often used alongside DMS. Option C is incorrect because Amazon Redshift Spectrum is for querying data in Amazon S3, not for database migration.

Answer

Use AWS Backup to take a full backup and restore to Amazon RDS.

Answer

Use AWS Schema Conversion Tool (SCT) to convert the schema and perform a homogeneous migration.

Answer

Use Amazon Redshift Spectrum to query the data in place.

Question 10

A company is migrating an SAP HANA system to AWS using a homogeneous copy. The source database is SAP HANA 2.0 on SUSE Linux, and the target is also SAP HANA 2.0 on AWS. Which AWS service can be used to transfer the HANA backup files to Amazon S3 efficiently?

Accepted Answer

AWS DataSync. AWS DataSync is the best choice for efficiently transferring large SAP HANA backup files to Amazon S3. It is a managed data transfer service that can automate and accelerate moving data over the internet or AWS Direct Connect. Option A (AWS DataSync) is correct. Option B (AWS Storage Gateway) is designed for hybrid cloud storage, not for large-scale file transfers to S3. Option C (AWS Direct Connect) provides a dedicated network connection but is not a data transfer service itself. Option D (Amazon S3 Transfer Acceleration) can speed up S3 uploads but is only an acceleration feature, not a managed transfer service like DataSync.

Answer

AWS Storage Gateway

Answer

AWS Direct Connect

Answer

Amazon S3 Transfer Acceleration

Question 11

Which TWO considerations are critical when planning a migration of an SAP system to AWS? (Choose 2.)

Accepted Answer

Storage performance and IOPS requirements. The two critical considerations when planning an SAP migration to AWS are storage performance (IOPS) and network connectivity/latency. Storage performance is critical because SAP databases require high IOPS for optimal performance, and insufficient IOPS can lead to significant degradation. Network connectivity and latency between SAP components (e.g., application servers and database) are also critical to ensure low-latency communication and avoid performance bottlenecks. Option B (AWS Region availability) is not as critical because SAP can run in any region that supports required services, though it may affect latency. Option C (database compatibility) is important but a separate migration decision, not a top-level planning consideration. Option E (number of security groups) is a security configuration detail, not a critical factor for migration planning.

Answer

AWS Region availability for SAP services

Answer

Database compatibility with target

Answer

Number of security groups allowed

Question 12

A company is migrating a legacy SAP ERP system to AWS. The migration must be completed over a weekend to minimize business impact. The SAP application relies on a custom kernel that is not supported by the AWS SAP HANA Large Instances. What is the best approach?

Accepted Answer

Use an SAP-certified EC2 instance with the existing kernel. SAP on AWS supports both HANA Large Instances and certified EC2 instances. Since the custom kernel is not supported on HANA Large Instances, the best approach is to use an SAP-certified EC2 instance that can accommodate the existing kernel. Option C is correct because it avoids the unsupported kernel issue without requiring a kernel update. Option A is incorrect because HANA Large Instances do not support the custom kernel. Option B is incorrect because contacting SAP for a supported kernel may not be feasible within the weekend migration timeframe. Option D is incorrect because re-platforming to a supported kernel introduces additional risk and complexity.

Answer

Migrate to SAP HANA Large Instances and update the kernel

Answer

Contact SAP to obtain a supported kernel version

Answer

Re-platform the application to use a supported kernel

Question 13

Refer to the exhibit. An SAP HANA system is running on an EC2 instance with the attached volumes shown. The HANA system requires high IOPS for its data volume. Which volume should be used for the HANA data directory?

Accepted Answer

vol-1a2b3c4d5e6f78901 (io1). The io1 volume (vol-1a2b3c4d5e6f78901) provides 10,000 IOPS, which is significantly higher than the gp3 volume's 3,000 IOPS. SAP HANA data directory requires high IOPS for optimal performance, making the io1 volume the best choice. Option A (using both volumes for striping) is unnecessary and adds complexity, while Option B (gp3) has insufficient IOPS. Option C (instance store) is ephemeral and not suitable for persistent HANA data. Therefore, Option D is correct.

Answer

Both volumes for striping

Answer

vol-0a1b2c3d4e5f67890 (gp3)

Answer

Neither volume; use instance store

Question 14

An SAP system on AWS is experiencing high latency between the SAP application servers and the HANA database. The application servers are in a different Availability Zone than the database. Which change should a migration specialist recommend to reduce latency without increasing costs significantly?

Accepted Answer

Deploy SAP application servers in the same placement group and Availability Zone as the HANA database. Deploying SAP application servers in the same placement group and Availability Zone as the HANA database minimizes network distance and reduces latency without additional cost. Option A is incorrect: Enhanced Networking improves throughput and reduces packet loss but does not eliminate cross-AZ latency. Option B is incorrect: VPC Peering is used for inter-VPC connectivity, not for reducing latency within the same VPC. Option C is incorrect: using larger instance types does not necessarily reduce network latency and would increase costs.

Answer

Enable Enhanced Networking on all instances

Answer

Create a VPC Peering connection between the application and database subnets

Answer

Use larger instance types for the application servers

Question 15

An organization is planning a migration of SAP applications to AWS. Which AWS service should be used to track and manage the migration project's tasks and milestones?

Accepted Answer

AWS Migration Hub. AWS Migration Hub provides a single location to track migration progress across multiple AWS and partner tools, making it the appropriate service for managing migration project tasks and milestones. AWS Config (Option A) is for compliance and resource tracking, not migration management. AWS Systems Manager (Option B) is for operational management, not migration tracking. AWS CloudFormation (Option D) is for infrastructure as code. Therefore, Option C is correct.

Answer

AWS Config

Answer

AWS Systems Manager

Answer

AWS CloudFormation

Question 16

A company is migrating an SAP HANA system to AWS using SAP HANA System Replication (HSR). The migration must have a Recovery Point Objective (RPO) of less than 15 minutes and a Recovery Time Objective (RTO) of less than 2 hours. Which TWO actions should the company take to meet these objectives?

Accepted Answer

Deploy the target system in a different Availability Zone. To meet an RPO of less than 15 minutes and an RTO of less than 2 hours for an SAP HANA migration using HSR, the company should deploy the target system in a different Availability Zone (option A) and configure SAP HANA System Replication in synchronous mode (option E). Synchronous replication ensures that data is written to both source and target before the transaction is committed, providing near-zero RPO. In the event of a failure, the target can be promoted quickly, meeting the RTO of under 2 hours. Option B (using EBS snapshots) would not achieve the required RPO as snapshots are periodic and not continuous. Option C (placing the target in a different region) would introduce higher latency and potential RPO/RTO challenges. Option D (single Availability Zone) does not provide redundancy and would increase risk.

Answer

Use Amazon EBS snapshots for data replication

Answer

Place the target system in a different AWS Region

Answer

Use a single Availability Zone for both source and target

Question 17

A company is migrating a 5 TB Oracle data warehouse to Amazon Redshift. They need to minimize downtime and ensure data consistency. Which migration approach should they use?

Accepted Answer

Use AWS DMS with ongoing replication and perform a cutover. Using AWS DMS with ongoing replication and performing a cutover ensures data consistency and minimizes downtime during the migration. DMS replicates changes in real-time, allowing a final cutover with zero data loss. Option A (Oracle UNLOAD and COPY) requires significant downtime for export/import. Option C (Amazon Kinesis) is for streaming, not bulk migration. Option D (AWS SCT for schema conversion) only handles schema, not data transfer.

Answer

Export data using Oracle UNLOAD and COPY into Redshift

Answer

Stream data using Amazon Kinesis and then load into Redshift

Answer

Use AWS SCT to convert schema and then manually copy data

Question 18

Refer to the exhibit. An administrator is trying to restore an SAP HANA backup from an S3 bucket but receives an AccessDenied error. The administrator has full EC2 and S3 permissions via an IAM role attached to the EC2 instance. What is the most likely cause?

Accepted Answer

The S3 bucket has a bucket policy that denies access from the instance's IAM role. The AccessDenied error indicates an authorization failure. Since the IAM role grants full EC2 and S3 permissions, the issue is likely an explicit deny in the S3 bucket policy that overrides the IAM allow. Option A (different region) would cause a redirect error, not AccessDenied. Option B (SSE-C) would produce an encryption-related error. Option C (wrong command syntax) would result in a syntax error. Therefore, option D is correct: the bucket policy denies access from the instance's IAM role.

Answer

The S3 bucket is in a different region than the EC2 instance

Answer

The backup file is encrypted with SSE-C and the key is not provided

Answer

The administrator used the wrong S3 command syntax

Question 19

A company is migrating a production SAP HANA database to AWS. The database size is 2 TB. The migration window is 4 hours. The network bandwidth is 10 Gbps. Which migration method should be used to achieve the shortest downtime?

Accepted Answer

Use SAP HANA System Replication.. SAP HANA System Replication can achieve near-zero downtime, which is critical for a 2 TB database with a 4-hour migration window. With 10 Gbps bandwidth, initial sync completes well within the window, and ongoing replication minimizes downtime during cutover. Backup and restore (A) would likely exceed 4 hours due to data size. AWS DMS with CDC (B) introduces overhead and is not optimized for HANA system replication. AWS Snowball Edge (D) is unnecessary given the high bandwidth and would add latency for initial load.

Answer

Use a backup and restore approach.

Answer

Use AWS DMS with full load and CDC.

Answer

Use AWS Snowball Edge for initial load, then CDC.

Question 20

Your SAP system on AWS uses a shared file system with Amazon EFS. The operations team notices that the SAP application is experiencing latency when reading files from EFS. Which action can improve read performance?

Accepted Answer

Enable EFS performance mode 'max I/O'.. Enabling EFS 'max I/O' performance mode increases the file system's ability to handle a high number of concurrent read operations by distributing data across multiple servers within the AWS region. This mode is specifically designed for workloads like SAP that require high throughput and low-latency access to shared files, as it scales I/O operations horizontally without the bottleneck of a single file server.

Answer

Use Amazon FSx for Windows File Server instead.

Answer

Move the file system to Amazon EBS with provisioned IOPS.

Answer

Use Amazon S3 with Transfer Acceleration.
