PAS-C01 Mock Exam 89 — 25 Questions

Question 1

An SAP system uses a secondary IP address for the SAP application. After an instance reboot, the secondary IP address is no longer attached. What is the most likely cause?

Accepted Answer

The secondary IP address is not automatically re-attached after instance stop/start. When an EC2 instance is stopped and started, any secondary private IP addresses assigned to its primary Elastic Network Interface (ENI) are automatically released and not re-attached. The SAP application relies on this secondary IP address, so after a stop/start cycle the address is lost, requiring manual re-assignment or automation to restore it.

Answer

The Elastic IP address was not associated with the instance

Answer

The security group removed the IP address

Answer

The Elastic Network Interface (ENI) was deleted

Question 2

Question 3

A company runs SAP Business Suite on AWS. The database size is 2 TB. They need to restore the database to a point-in-time from the last 24 hours. Which AWS service should be used to achieve this with minimal impact on production performance?

Accepted Answer

Configure SAP HANA Backup & Recovery using Backint agent to Amazon S3.. SAP HANA Backup & Recovery using the Backint agent to Amazon S3 is the native, AWS-integrated method for performing point-in-time recovery (PITR) of SAP HANA databases. Backint offloads backup and restore operations directly to S3, bypassing the EC2 instance's I/O stack, which minimizes performance impact on production workloads. This approach supports incremental and log backups, enabling precise PITR within the last 24 hours without requiring full-volume snapshots.

Answer

Use AWS Backup with a backup plan for the EC2 instance.

Answer

Use Amazon EBS snapshots of the database volume.

Answer

Use AWS Database Migration Service (DMS) for continuous replication.

Question 4

Answer

Establish VPN/Direct Connect, deploy EC2 instance, install and configure SAProuter, open port 3299, configure routing.

Answer

Deploy EC2 instance, install and configure SAProuter, establish VPN/Direct Connect, open port 3299, configure routing.

Answer

Deploy EC2 instance, establish VPN/Direct Connect, install and configure SAProuter, open port 3299, configure routing.

Question 5

A company is migrating a large SAP Business Warehouse (BW) system to AWS. The system uses SAP HANA as the database. The migration plan involves using SAP HANA System Replication (HSR) for near-zero downtime. During the initial synchronization, the network bandwidth is limited to 1 Gbps. The source database is 5 TB. How long will the initial synchronization approximately take, assuming no other bottlenecks?

Accepted Answer

Approximately 12 hours. 5 TB = 5,000 GB = 40,000 Gb (since 1 GB = 8 Gb). At 1 Gbps, time = 40,000 seconds ≈ 11.1 hours. This simple calculation ignores overhead, but among the options, 12 hours is the closest. The other options are unrealistic.

Answer

Approximately 2 hours

Answer

Approximately 6 hours

Answer

Approximately 24 hours

Question 6

Question 9

An SAP on AWS environment is experiencing intermittent connectivity issues between the SAP application servers and the SAP HANA database. Both are in the same VPC but in different Availability Zones. The network team has confirmed that the security groups allow traffic on the required ports. What is a likely cause of the issue?

Accepted Answer

Network ACLs are misconfigured, blocking return traffic.. Network ACLs are stateless, meaning they evaluate inbound and outbound traffic separately. Even if inbound rules allow traffic from the SAP application servers to the HANA database, the outbound rules on the database subnet's NACL must explicitly allow the return traffic (ephemeral ports) back to the application servers. Misconfigured outbound rules in the NACL can drop the response packets, causing intermittent connectivity issues between the application and database tiers across Availability Zones.

Answer

AWS Shield Advanced is blocking legitimate traffic.

Answer

VPC Flow Logs are enabled and dropping packets.

Answer

The VPC is using AWS Direct Connect, which adds latency.

Question 10

A company runs SAP ERP on AWS with an Oracle database. The architect wants to implement a backup strategy that provides point-in-time recovery (PITR) with an RPO of 5 minutes and an RTO of 2 hours. Which TWO solutions should the architect consider? (Choose TWO.)

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication to an Oracle instance in another AZ. AWS DMS with ongoing replication can continuously replicate changes from the Oracle source database to a target Oracle instance in another Availability Zone, enabling point-in-time recovery with an RPO as low as 5 minutes. This approach supports near-real-time replication and can be combined with automatic failover to meet the RTO of 2 hours, as the target instance is already synchronized and ready.

Question 11

A company is migrating its SAP landscape to AWS. They need to choose a migration method for each system. Which TWO factors are most important to consider when selecting a migration method for SAP systems? (Choose TWO.)

Accepted Answer

Source and target platform (OS, DB). Options C and E are correct. The source and target platform (OS, DB) and SAP release/database version are critical because they determine the availability and compatibility of migration tools (e.g., SUM, DMO, SWPM). Option A (total cost) is a business consideration, not a technical factor for method selection. Option B (backup frequency) relates to operational planning, not method choice. Option D (number of SAP users) affects sizing but not the migration method itself.

Answer

Total cost of migration

Answer

Frequency of database backups

Answer

Number of SAP users

Question 12

A company runs SAP Business Suite on AWS with Oracle Database. The system is experiencing high read latency on the database server. The current storage configuration uses EBS gp2 volumes. Which change would most effectively reduce read latency?

Accepted Answer

Migrate to io2 Block Express volumes with provisioned IOPS.. Io2 Block Express volumes provide consistent, high-performance IOPS with sub-millisecond latency, which directly addresses the high read latency issue. Unlike gp2, which relies on burst credits and has variable performance, io2 Block Express delivers provisioned IOPS up to 256,000 per volume, making it ideal for latency-sensitive SAP workloads with Oracle Database.

Answer

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

Answer

Configure a RAID 0 stripe across multiple EBS volumes.

Answer

Use EBS st1 volumes for better throughput.

Question 13

Refer to the exhibit. An SAP administrator is reviewing the EBS volume configuration for a SAP HANA /hana/data volume. The volume is 500 GB gp2 with DeleteOnTermination set to false. The instance is in us-east-1a. Which action should the administrator take to improve performance for SAP HANA?

Accepted Answer

Modify the volume to gp3 and provision 5000 IOPS.. SAP HANA requires a minimum of 5000 IOPS for /hana/data. The gp2 volume provides 1500 IOPS (3 IOPS per GB). The administrator should either increase the volume size to at least 1667 GB to get 5000 IOPS, or change to gp3 with provisioned IOPS of 5000 or more. The best practice for SAP HANA is to use multiple volumes in RAID 0, but the question asks about improving performance for this volume. Changing to gp3 with higher IOPS is a direct improvement.

Answer

Take a snapshot and create a new volume in us-east-1b.

Answer

Enable encryption on the volume.

Answer

Set DeleteOnTermination to true.

Question 14

Which THREE AWS services are typically used in the migration of an SAP environment to AWS? (Choose 3.)

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is correct because it enables the migration of SAP HANA, SAP ASE, or other SAP-supported databases to AWS with minimal downtime. DMS supports homogeneous migrations (e.g., SAP HANA to SAP HANA on Amazon RDS or EC2) and heterogeneous migrations (e.g., SAP ASE to SAP HANA) when paired with the Schema Conversion Tool (SCT). It handles ongoing replication via Change Data Capture (CDC), which is critical for SAP systems that cannot tolerate extended outages.

Answer

AWS Direct Connect

Question 15

A company is running SAP on AWS and needs to ensure that its SAP HANA database is backed up daily with minimal impact on performance. The database is 2 TB in size and runs on an r5.8xlarge instance. Which backup strategy meets these requirements?

Accepted Answer

Use the SAP HANA Backint agent to back up directly to Amazon S3. The SAP HANA Backint agent integrates directly with SAP HANA to stream backup data to Amazon S3, which offloads the backup workload from the database instance's CPU and I/O. This minimizes performance impact compared to local EBS snapshots or volume-based backups, as Backint uses S3's scalable throughput without consuming instance storage bandwidth.

Answer

Perform a full backup to Amazon EBS volumes attached to the instance

Answer

Use AWS Backup to create snapshots of the entire EC2 instance

Answer

Use AWS Storage Gateway to back up to Amazon S3 Glacier

Question 17

A company runs SAP on AWS and needs to implement a disaster recovery strategy for their SAP NetWeaver system. The primary site is in us-east-1, and the DR site is in us-west-2. They want to minimize data loss and recovery time. Which approach meets these requirements?

Accepted Answer

Use SAP HANA System Replication in asynchronous mode across regions.. SAP HANA System Replication in asynchronous mode across regions is the correct approach because it provides near-zero recovery point objective (RPO) with minimal impact on primary system performance, while enabling rapid failover to the DR region in us-west-2. Asynchronous replication is suitable for cross-region scenarios where network latency would make synchronous mode impractical, and it meets the requirement to minimize both data loss and recovery time for SAP NetWeaver.

Answer

Use SAP HANA System Replication in synchronous mode across regions.

Answer

Use AWS Backup to back up the SAP HANA database and restore in us-west-2.

Answer

Use Amazon S3 cross-region replication for SAP HANA data files.
